September in Brief


   Early in the month I finished the half of the south wall that I had started. Then I stapled on some "Tyvek". This oddly made HDPE sheet or fabric is supposed to not allow liquid water through, but to allow water vapor to pass. That way, the house shouldn't get wet from the outside, but if a wall does get damp, it can dry out. It sounds like aluminum foil, "crinkley" quite loud, when flexed.
   I had given no thought to such a "hyped" modern building material, but my neighbor took some rotten cedar boards off at the bottom of the windward/seaward face of his cottage, exposing the tyvek. Then he took the tyvek off expecting to also have to replace the boards behind it, but was amazed to find that they were still in good shape. So I decided it must be worth putting on.

   I did get it up on the gable end section. Seems I didn't take a picture. Both windows are in, but I don't yet have a door. Somehow I haven't had time even to continue with the other half of that wall!

"T-Plug" Connectors

   Sometime early in the month I made a shell to enclose the cord wires for appliances, and a socket-pin holder in order to replace the cheap plastic ones with higher temperature nylon. Then, losing 1.6(?)mm in the wall plate and .8mm in the shell (2.4mm?), the plug and socket didn't fit together very solidly. I redid the wall plates so the sockets were only recessed by .8mm.
   Later it occurred to me that if I was making [nylon] socket shells anyway, I could make their shape a bit different, putting a lip around the back edge so they would fit into wall plates flush with the front, without danger of them pulling out through the front when a cord was unplugged. Then only the plugs (no lip) would need the .8mm face in front of the wire enclosure shells.

   On the 18th I checked for a picture of loose T-Plugs on AliExpress (for the August newsletter, still not quite finished) and found "mini T-Plugs". They had a nylon shell, that already had a lip! Perfect! But I found a dimensional drawing. "Mini" was a very small size! I couldn't find the regular size with nylon shells or lips. Rats!

Next Change of Plans...

   Hmm... Well, in order to further simplify, perhaps "mini T-Plugs" could be the 12 volt size, and "regular T-Plugs" could be for 36 volts? Since the "mini" came in nylon (and had a lip!), I wouldn't have to 3D print bodies, or cover the ends to put them into outer housings like wall plates and cord covering enclosures - they could be inserted flush. They were rated at 10 amps, which seems (if only just) large enough for lighter loads like 12 volt lights and things. In fact they were smaller than USB plugs and sockets, often used as 5 volt connectors. I think for a 12 volt standard plug, people would like that. If some heavier connectors for high current applications (heavier appliances and inverters) were also available, they could be just what was wanted for most 12 volt wiring, and I ordered 60 pairs. (for about 25$C)

   I also found the original WSDeans.com designer company. But they were rather costly compared to any store on AliExpress, and being (presumably) in USA, they would probably insist on courier shipping which would entail higher customs charges. And they didn't have any with nylon shells either. It seemed unfortunate that it looked impractical to work with those who had designed the connectors in the first place.

   I had already designed nylon shells for these "regular" T-Sockets, and could easily add a lip to them. So if the "mini" ones could be for 12 volts, and the "regular" ones for 36, that should pretty much solve both connector systems. All that would still be needed would be "maxi" size "T-Plugs" and "T-Sockets" for higher amperage appliances - in two different sizes, for 12 volts and 36.

[19th] Still it was aggravating that there seemed to be no regular T-Plugs in a high temperature material. In the morning I looked again "plastic" - "plastic" - "rubber" (huh?) - "plastic" - "plastic" - but finally at "Fanjay": "nylon". (I'll assume it's true. You never seem to be entirely sure with some of these Chinese companies.) Yay! So I ordered a bunch of their sockets (30 or 40) and 10 of their plugs. (all under 20$C) They turned out to have several ridges intended to give a better hand grip, but one especially wide one could be considered to be a lip to hold them in an outer shell, fitting flush at the front. (I won't have to keep swapping filaments if I didn't have to print anything in nylon. ...Maybe I should get a second 3D printer anyway? or even one for each type of filament I want to print? 3 or 4? That would make it all easier, but I would have to justify the cost of the printers, which would at least mean I'd have to be selling things. But of course that is exactly the intent of making 12V and 36V off-grid infrastructure equipment.)
    All this T-Plug connector shopping not only wasn't breaking the bank, but it seemed like it would save an awful lot of time over making my own pieces.

The New Lithium-Ion 3.7V, 120 AH Batteries

   I had ordered 35 of these cells and got them in August. I'm not sure why I picked that number - at first I was just going to get 20. My friend Jim Harrington in Victoria who had told me about them had bought 10 for 36 volts. In mid September he decided he wanted to go up to 48 volts, but BatteryHookup.com didn't have them any more. So I sent him three in a swap/buy arrangement wherein I got a 24 volt balance charger and some money. So I had 32.
   (He also sent me the balance charger for the 11 Lithium-iron phosphate cells that he had given me some years ago, that I had thought I didn't want at that time. Now I could put these same 11 cells together in their original 36 volt configuration as 36 of the 72 volts for the Miles truck. Thanks Jim for saving it all this time!)

   3.7 volt Lithium-ion cells need just 10 cells for 120 amp-hours, 36 volts (actually 37V). Ten of them in a cardboard box weighed just 44 pounds. How best to utilize them?
   Using seven for 24 volts for electrifying the lawn tractor would leave 25. That would be awkward unless it was to be three sets of seven and one set of ten for 36 volts.
   Twenty would give the Miles mini cargo truck 74 volts at 120 amp-hours. That would leave twelve. Ten was really too few for the Sprint car - it would only provide 120 amp-hours, which isn't much at just 36 volts.
   Using all thirty of them (with two spare cells) for the Sprint car (should I ever get it going) would provide 360 amp-hours at 37 volts: 13,320 watt-hours, for just 150 pounds weight. But the Sprint, running or not, can be plugged into the adjacent solar battery backup power system for the house, to provide that energy and recharge from solar if the grid goes down.

   This seemed like the most practical use. (With the old ones it was 36 lithium-iron phosphate 3.2 volt cells giving ~38 volts and 300 amp-hours: 11,400 watt-hours for 270 pounds weight.) I would just have to run the other 36 volts of the truck off 11 or 12 the leftover 'misbhaving' Li-Po batteries, giving it just 72V, 100AH or 7200 watt-hours. Enough to get to town, I should think, but needing a recharge to return home. I think I've spent all I want to on batteries for a while!

   To get 12 volts for the car's lights and all, instead of another battery I would simply use a DC to DC down converter that turns on with the key. That will also provide an even drain on the whole 36 volts, instead of the previous simple setup which ran the lights off the lowest 12 volts of the 36.
   On the 16th the three 10 cell balance chargers arrived. I still need some aluminum bars to tie the "sliced off" power tabs together on these new but surplus cells removed from EV cars. (On order.)

A 12V LED "COB" Light

[Sept 4th] I had some months ago bought some 12 volt "COB" ("Chip On Board") flat LED modules. It had occurred to me to make some 12V lights with CAT - now T-Plug - plugs on the end of the cord as plug-in lights. When I took the clamps off the older batteries (TE News #147), it occurred to me that the aluminum ends looked just about right to be heatsinks for these COB light 'sheets'. Even the screw holes were in just the right place.
   It now - perhaps long belatedly - occurred to me that an easy way to make LED light housings would be to 3D print them. In fact, that proved almost dead simple, especially compared to cutting and gluing pieces of flat plastic as I had done before. I just had to put a diffuser piece on the front. Why hadn't I thought of it before, long ago?
   The housing, printed out that day, looked perfect but it had a serious flaw: in spite of the open back, once the diffuser was glued on there would be no way to get the LED and heatsink assembly in.

(Sept. 5th] I cut one end open with a hacksaw and a thin blade ("coping"?) saw. I decided that these housings would have to be made in two pieces, with an end that screws or snaps on. Given that, I finally have an LED light design that isn't a pile of work to put together. (I suppose it's still simpler to order existing lights from China. The COB plates come from there anyway.)
   I was about to cut the diffuser plastic, then I remembered that methylene chloride doesn't solve PLA. Hmm. What about MEK? It would glue somehow... but for a final design maybe a slide-in diffuser? I printed an unsuccessful and then a mediocre but workable housing with a slide-in diffuser slot, in which I also added space for a three-position switch (bright-off-dim) and a couple of current limiting resistors. That was much better, with good access front and rear to the screws to fasten the LED/Heatsink assembly to the housing. One screw can hold the diffuser from sliding out after assembly.

First try at a 3D printed housing

LED COB panel shown facing the rear.
The LED/heatsink assembly won't fit in from the rear.

Third try enclosure with high-off-low switch,
current limiting resistors, slide-on diffuser.

Turned on "low".
The two previous attempts are on the right.

The Time, the Time!

   Next I was going to do a housing for the down converters, the DC to DC version of universal power adapters. And maybe print some actual nylon T-plug sockets (before I found some nylon T-plugs on line), and then wall plates and wire shells to match them. These little things didn't seem like a tall order.
   But somehow after designing and printing just these three items, I didn't seem to have any more time for even the smallest renewable energy project. (How could I not have pulled that shaft out of the truck and balanced it yet?)

   One day I simply took three hours when I should have been doing something else and put the batteries into the model ground effect craft. This time the motors had plenty of power to slide the model across the floor and it was evident it had lots of power to take off. But it still needs a control to steer using the two motors, and anyway the 'throttle' needs to be reversed so if the model loses communication with the transmitter/control, it stops instead of going to full throttle and hitting a tree or vanishing into the distance. (I cannot for the life of me imagine why they are made that way.) I've ordered some CA3260 OpAmps for that, on discovering that I can't find the tube of them I thought I had.

   It seemed my nephew was never going to make it up here after all (I was hoping that if he visited as he had said, he would like it and decide to stay, at least for a summer), and I had decided to rent out my travel trailer. A lady who says she wants to garden and is bringing chickens and ducks wants to rent it, and on top of trying to put up walls on the post-and-beam house frame (presently enclosing that trailer) and everything else, I had to get some things ready for her.
   Where are all the days, weeks and months going? I'm starting to despair of ever finding time to complete any of the major projects like the everlasting nickel-manganate-zinc batteries, the 100% efficient variable torque converter, the unipolar, permanent magnet assisted ultra efficient BLDC motor and controller, a rotary air compressor-decompressor for open loop air heat pumping, 'free' electricity from HE rays, and so on.
   But perhaps there will yet come a time when at least some of these things can be brought to completion - and hopefully commercialized.

"New" Nissan Leaf Batteries

   My friend Tom, now back in Victoria, found a source for supposedly "reconditioned" Leaf batteries for around 2000 $ each. Nissan refuses to produce new batteries for older Leafs, eg, 2011.
   They took a couple of months to deliver, and it turned out to be something of a scam. They were just old Leaf batteries with deteriorated range. However, it did provide Tom with three 'extra' cases, into which new batteries could be placed, and he's working on finding new cells that will fit, and in touch with a Chinese manufacturer. If that works out, he'll be able to make up batteries to give the cars back their full range. (or even more?)
   And he's selling one of them to a Leaf owner whose battery has become so poor he can hardly use the car - so it's still an upgrade!

   It appears that electric cars are likely to last for decades except for the batteries, and apparently there are hundreds of thousands of older Leafs that will be needing new batteries, so he may yet make a good business out of it.

   I've put about 30,000 Km on my own 2015 Leaf (total ~65,000), with little sign of battery deterioration. Sometimes I think it's averaging a couple of percent lower charge remaining than it used to have when I drive to town and back - something like 53% instead of 55%.
   (Maybe someday I'll get the "ultra efficient" Chevy Sprint project working, sell the Leaf, and be able to put in whatever batteries I please -- maybe even my 'everlasting' nickel manganate-zinc ones!)

Eliminating Skin Moles - It Works!

   Something I have continued experimenting with for some time is elimination of moles on my back and chest. Moles mostly seem to be caused by scratching. Being allergic to various pollens, my back can get horribly itchy. I gradually learned to put calamine lotion (or other anti-itch cream) on it, and never to go outside without a shirt on even in the warmest weather. In the meantime, having at one point in my late 20s had my doctor remove three I'd had since childhood, I had been free of any major moles. But in my 40s and 50s I gained several new ones, including some on my chest.
   And now the memory occurs that when I was about 4, my dad (then about 31) had found a wooden back scratcher with a long handle and was using it lavishly in the kitchen, saying "Ah, at last a back scratcher that really works!" Then when he was 70(?), I saw him with no shirt on and I was shocked: his whole upper and mid back was a mass of moles and skin lesions! I'm sure they were a major contributor to his ill health and death, although he lived to age 84. And that the scratching all those years ago was the cause of the later appearing moles.

   Perhaps a year ago I switched to using the same thing I have used before for skin tags and an occasional wart: a mixed paste of castor oil and baking soda. I simply keep it in an old jar lid on the bathroom counter. It doesn't stay mixed very well, and one uses a finger to pick/mix up an amount for a good paste at the time of application.
   My doctor once surgically removed a mole (one of the three originals), and some years later the whole area flared up into major problems, sometimes becoming a giant "spider" of red lines. (I recall that being 2004.) I had to have cool showers because any warmth would trigger it. A treatment of boiled mullein leaves ("mullein stupes") taped on would bring it under control and (I suspect) prevented it from killing me. I finally killed it with lavish applications of Compound W, finally burning pretty deep into the skin to at last get rid of the root that kept coming back time after time. (At least, there's been no sign of it since.)

   So, knowing that agitating moles can make them worse - even much worse - my technique was somewhat different. Instead of massaging the moles with the mixture, I only rubbed - almost dabbed - it on very gently, just to soak the mole in the mixture.
   I had one "crusty", rough mole growing on my chest, and one that had been on my back for some time, a few dark ones with smooth surfaces, and various small bumps from almost colorless to darker. For quite a while, nothing seemed to be happening, and I only treated them once every two or three days. Perhaps that wasn't often enough.

   I had a dream in which there were some little dark scorpions sitting on my chest. They were just sitting there doing nothing, but being scorpions, they probably had potential to be dangerous if disturbed. I simply pointed a finger at one and it fell off. In the intricacy of details I was sure that the "scorpions" were my moles, and "pointing my finger" at them had to be the dabbing of the castor oil and baking soda mix onto them - but without agitating them.

   So then I went at them a bit more often, every day or sometimes two days, but even more gently than before. I had become fairly skeptical about actually getting rid of any as there had been no discernible signs of changes. They didn't even seem to lighten up in color as well as when I was using "Atoma Triple Antibiotic cream" or hydrocortisone cream. But I kept at it.
   Suddenly one day, the one on my chest started crumbling off in little pieces as I applied the paste, over a very few days. Of course that made me more enthusiastic than all those many months with no apparent results, and I started doing it daily for sure (I usually did it before bed) or even an extra one on the two rough moles in the morning. Soon it was gone, leaving a patch of dark but smooth skin that was smaller in extent than the mole had been. (image, right) That has been lightening up. I don't know if it will disappear or not.

   Next, near the end of September the crusty one on my back started to disintegrate. Of course I started giving it two soakings a day. At this point - which was really some ways into the disintegration - it finally occurred to me to take photos.

(It was hard to hold the cell phone behind my back, aim it, and press the right spot on the screen to get these pictures, and the focus especially on the second one is poor in spite of several attempts. The orientation or camera position may be different too.)

 By October 3rd there was just a bit of it left and I trust that won't last much longer. (mostly just smooth skin by 6th. I may have gotten a little overzealous and irritated the last bits, causing them to fight back.) With this one I don't see a patch of dark skin.
   The smooth surfaced moles don't seem to have changed much. Perhaps they aren't amenable to this particular treatment or mixture, or perhaps they'll gradually become more rough surfaced and then start to vanish like these two did. But these two always seemed to be rough.

   I will say that rather extreme patience is required. I've been trying three different substances on the moles for maybe 3 years now. My best idea of what seems to be a "winning" formula is now to wet the mole(s) with castor oil and baking soda paste at least daily, or maybe twice daily, on crusty, rough surfaced moles. Very gently, without physically/mechanicly agitating the mole.
   I will continue to try on the smoother moles and see if I can eventually eliminate them. At least I have two fewer to do now!

Explaining Those Nasty California Fires

   In 2018 a couple of fires in California were so bad and so hot, and spread so fast, that people were led to speculate that foul play was afoot - that it seemed like some sort of bizarre conspiracy. The worst of it was that suddenly an area would be ablaze when there seemed to be no way the fire could have spread to there so fast from where it had been. I fell for these ideas for a time myself. Now the 2020 California fire season has been even worse, replacing 2018 as the worst in recorded history.

   An article I read somewhere recently gave the real reasons, which are multiple. First of course is the inherently hot, dry summer climate of California. This turns flammables into matchsticks waiting for a source of ignition. California will always have fires.
   Second is a century and more of putting out fires. Normally fires burn up whatever there is to burn, which in California was often but not big fires, for the very reason that it is so flammable. What these rather successful firefighting efforts have done is cause more and more flammable material to pile up. Now when it ignites, the fires can be huge.
   Third is the population growth. People unable to afford homes in the existing urban centers go farther afield and build new towns such as Paradise in the margins between fields and forests, next to all those flammables. That makes the fires more devastating to more people.
   Fourth, global warming with excessively high temperatures and drought contributes its part. The main effect is to exacerbate the dryness, but it probably also makes it easier to ignite whatever there is to burn.
   (I will comment here that long-persisting jet trail clouds covering the sky at high altitudes, damping the natural convective forces that cause global wind circulations, whether incidental to jet air travel or created deliberately, are the obvious cause of both extra heat and of greater drought in many areas.)

   In all this some critical threshold has been crossed, that has set everything up for the recent cataclysms. When (it was never "if") a fire starts, it has far more dead, flammable wood to burn than ever before, piling up in some places for a century. So instead of just burning the understory and not getting up to the crowns of the trees, the whole forest soon blazes up. When the fire reaches a certain size and intensity, everything flammable anywhere near the fire ignites ("flashover"), and a "firestorm" or "fire tornado" develops. If I understand correctly, this phenomenon had never been seen since the firebombing of (eg) Dresden and Tokyo in world war two. It now started occurring in California.
   In this, a vortex of tornado or hurricane force winds develops and sends flaming debris far up into the sky - I recall seeing the figure 17,000 feet. This debris, still burning, can come down miles away - downwind or upwind - and ignite whole new areas that no one thought the fire could possibly reach so fast. It can destroy power lines and knock out electrical stations.

   Here then are explanations for some of the strange phenomena that were being attributed to some mad arsonistic conspiracy: the savage winds that come up out of nowhere on a fairly calm day that seem to rapidly spread a fire that otherwise should have been controllable, and the incredibly fast spread of a fire, with fire suddenly raining down from the sky in a new area, for example on (eg) a town like Paradise that just minutes before had seemed to be a still a good distance from the fire, and perhaps, inside the fire tornado, the sudden ignition and fierce burning of guard rail posts and sign posts (not to mention parked cars) over a considerable stretch of road or highway.

Gardening & Chickens

Wheat Growing Experiment

   On the 7th I harvested the wheat from the open garden. The stalks of the first planted kamut and red fife were yellow to brown. The later planted ones were turning but most of the stalks still were or still had some green.
   But I snipped all the heads off with a pair of scissors. My little by-hand harvest took half an hour. I'll save most of it for some future planting, perhaps next year.
   Later I bought a 10 Kg bag of kamut seeds/kernels from a health food store. I may plant my front lawn next spring. (Hay, that's less to mow!)

Other Vegetables

      Blueberries - Half picked before I thought to take a picture
   I had planted 4 blueberry plants in 2018. One had lots of tiny berries that year but died at the end of the summer in spite of receiving exactly the same treatment as the other three as far as I could tell. The other three had fewer but much larger berries - more the size one finds in groceries. I thought one of those had died at the end of 2019 - I almost yanked it out. It came back but had no berries in 2020.
   In late August I had picked around 1/2 a cup of blueberries from the other two. (I used them in cookies and pie.) There were still unripe ones. On the 8th, to my surprise I got another full cup, which weighed in at 140g. So probably somewhere around 250-300g total. Not bad for two little bushes! And apparently they grow bigger than I thought, and I should have planted them substantially farther apart -- and not under my livingroom bay window. I was more expecting good harvests of cherries, apples and pears by now from trees planted in 2017, but I'll go with what's working, and plant more blueberry bushes!
   From the characteristics, the similar stems, leaves and berries, I would guess blueberries and salal are pretty closely related. But this year the salal berries are all but refusing to come off the stems for some reason, instead squishing if tugged at too hard. They haven't been worth trying to pick.

The corn that the plastic protection soon ripped off
of didn't grow very well or produce any corn.
When small, half of it was shaded by the dirt pile behind
the fence, and it didn't even grow out of that shadow.
I did get a dozen delicious "half cobs" from the
at-first plastic covered patch by the house.

The Chickens

   I think I made a mistake when I fed the chickens - just two now - some bird seed which had been lying around in a plastic bucket with a lid. After that, they wouldn't eat chicken feed any more. On the 15th I checked the chicken penthouse and found two small green eggs. My almost 5 month old hen was laying!

Small Thots


* Why does the "new year" begin at such an arbitrary time? Why shouldn't it be right on the winter solstice, presently called December 23rd? Pretty much move everything ahead by 9 days. Then the summer solstice and the two equinoxes would also fall on the transition dates between two months. The whole calendar would make much more sense.

January, February, March: Winter Solstice to Spring Equinox.
April, May, June: Spring Equinox to Summer Solstice.
July, August, September: Summer Solstice to Autumnal Equinox.
October, November, December: Autumn Equinox to Winter Solstice.

* And while I'm at it, Why is February shorted by two days while January and March each have an extra? If they each donated a day each month would have: 30-30-30-30-31-30-31-31-30-31-30-31 days. Since that's a bit lop-sided (which it already is - 181 days in the first half, 184 days in the second half - oscurred by February), to even up the two halves of the year, perhaps the day should be taken from August instead of March, making it: 30-30-31-30-31-30-31-30-30-31-30-31.
   The leap year day could be added to any month - February for tradition, or perhaps to June, making it the exact middle day of the year.


* Why were banks and other money lenders about the only commercial institutions not included in the CoViD-19 shutdowns? It would have been only reasonable that interest on loans should have ceased to accrue for the same periods as all the other businesses were shut down and their customers weren't permitted to go about their lives and occupations. The same "time out" everyone else had to endure. Why was this one blood-sucking piece of non-essential economy permitted to freely collect? They are starting to find out that one can't suck any more blood from the corpse of an economy that these utterly unequal terms have very much helped to kill.

* From certain statistics it would appear there is a second wave of CoViD-19. In fact, it's in large part an illusion derived from the fact that the tests aren't perfect: there are about 2-1/2% false negatives and 2-1/2% false positive results. In the spring, only people going to hospitals were being tested. By the end of summer, tens of millions of people (UK example) were being tested. If for example 20 million people were tested, there would be about 500,000 "positive" "cases of CoViD" even if NO ONE AT ALL ACTUALLY HAD CoViD. This might be funny except that it's being used a reason (or pretext?) for a second "lock-down" (also in Victoria, Australia), even while only a small number of people are actually getting the disease, entering hospital or dying.

Covid Testing: Bad Science Worse Policy
Dr. Chris Martenson Sept 22nd 2020

Actual CoViD deaths.
There does seem to be a bit of a "second wave", but not as
serious as the first. Probably Ivermectin treatment helps.
Geographical distribution might also be interesting to see.
(The very end of the graph drops off because data isn't in yet.
I don't know the URL for the graph, or I'd get an update.)

   More and more doctors are warning that the health problems accruing from the simplistic focus on one virus are starting to result in far more medical deaths from various other causes than from the virus. (And that's without considering the economic calamity and disruption to the food supply chain!)

* Anyone who still thinks Palestinians are just rabble-rousing terrorists who have little real justification for hating Israel should probably look at this set of maps. It is awful what the Nazis did to the Jews in World War Two. Has Jewish treatment of the Palestinians been morally superior? Is Israel practicing their own "final solution" to "the Palestinian problem"? Last I heard they were still continuing to bulldoze Palestinian homes and "settle" their land with Jews. As I understand it, "Palestinian lands" are now little more than concentration camps.

* "Stop Procrastinating!" Isn't there something ironic about that order? Isn't stopping exactly what procrastinating is? (I guess that makes it a double negative.)

* I am a procrastinator. I crastinate much better than amateurcrastinators.

* The new version of OpenSCAD offers two views: "Orthogonal" and "Perspective". I wonder what an "Orthogon" is?

* Militium: a one man militia.

   "in depth reports" for each project are below. I hope they may be useful to anyone who wants to get into a similar project, to glean ideas for how something might be done, as well as things that might have been tried, or just thought of and not tried... and even of how not to do something - why it didn't work or proved impractical. Sometimes they set out inventive thoughts almost as they occur - and are the actual organization and elaboration in writing of those thoughts. They are thus partly a diary and are not extensively proof-read for literary perfection, consistency, completeness and elimination of duplications before publication. I hope they add to the body of wisdom for other researchers and developers to help them find more productive paths and avoid potential pitfalls and dead ends.

Electric Transport

Ground Effect Vehicle (1/4 scale model)

(24th) Someone wrote and asked me when the launch date would be. Busy as I was, it was really bothering me that I wasn't getting at my energy and electric transport projects except for the shortest and easiest things.
   I pulled out the old battery and set the new ones in, using epoxy and styrene foam to make padded comparments for them. There was lots more room for these smaller but more powerful batteries. I wired one up and tried it out.

At last, success!: the ducted fan blew up a storm. It had a ferocious, loud whine. It blew a calender off a nearby wall. And it slid easily across 3 different surfaces and then even a carpet, which was anything but slippery, twisting in sharp turns since only one fan was running. It looked like it would have plenty of power with two to get airborne with a very short take-off run.

   Again I note that after most of the first tests, I would absently turn the handheld transmitter/control off, and instead of stopping when it lost signal, the motor would rev up to full power and the model would start racing off. Heartstopper! I would quickly turn it back on and then turn off the circuit breaker in the model to turn off the motor power.
There's no way I'm letting this thing loose outside without reversing that! If I ever lost control, it could be gone out of sight and far away in a flash, or else ram into a tree or rock at high speed. It is a complete mystery to me why they would make the throttle controls backward like that. It seems to make no sense at all.

   I wired up the other side, then moved the receiver across and switched the control over. It ran and had a loud sound, but the model didn't move. It was turning in reverse. I swapped two phases to the motor and it worked great like the other one.
   It was nice to have the batteries plug in with the T-Plug connectors so they were easy to remove for charging.

   Well, I got something done. Then I went off to other things that were calling me. Hopefully I can put in some more short work sessions and get it all done ...soon.

(Next jobs:
 * More mountings (styrene foam blocks) to hold the batteries, and maybe the circuit breakers, in place.
 * Make the controls for the two motors operate in some rational way. (Note it steers by adjusting the two motors.)
 * Wire up the 7-wire socket to connect the balance charger's 7 wires to the battery's 7-wire plug.

   Later I remembered I had some mixed epoxy in the freezer from gluing my cracked shovel handle two days previously. It sets in hours at room temperature, but takes the better part of a week in the freezer, getting a little more viscous each day. (And I had then used some of it to make an epoxied 'sleeve' of polypropylene strapping for my epoxy-repaired wood-handle splitting maul. I had been meaning to do that for a long time.) I thought I might as well put the small remnant back in the freezer "just in case" I found a use for it. If not, it would simply set, as it would quickly do anyway if not kept cold.
   I cut some styrene foam blocks to fit and I managed to 'squeeze' out enough epoxy to glue them inside the foam hulls.

[26th] Surely the best way to make the control circuit would be with operational amplifiers (opamps). Since the power was just +5 volts and the control signals were 0 to 5 volts, obviously a 5 volt opamp with rail to rail outputs would be needed. No need to look that up - the obvious choice would be a CA3260 dual opamp, in the 8 pin DIP package.
   Now, where were they? I looked around my shop and racked my brain... where were the tubes of IC chips I used to have? I started to have a bad feeling they must have been thrown out when I moved. I got on line and ordered some via AliExpress.com . (And some heatsinks for LED COB lights while I was at it.) But if I couldn't find any kicking around somewhere, it meant yet another delay waiting for parts on the slow boat from China.
   Regardless of that, I had yet to lay out the circuit in EAGLE PCB, too, and make the PCB. With renting out my unprepared travel trailer the rest of the month (and well into October) was too busy for words, let alone for working on an energy project.

Things Noted - September 2020

* As the sun got lower, both the maximum generated and the daily totals kept dropping. Fully sunny days made over 11 KWH instead of 18 (the early summer best). If the panels were tilted farther to the south, say 30 or 40° instead of only 15, it would obviously make a big difference all year except during the summer.

* And the days got shorter fast. The equinox (Sept. 21st) is of course when the rate of transition from long days to short is greatest, and at 53.4°N, that change is from about 18 hours daylight in June to 6 in December.

* The string of bright days early in the month looked so promising. Alas, it didn't last. Like August, it was cloudier than September last year, which was cloudier than 2018.
