Putting together the emergency power box. Using the 18650 battery banks from my past videos for power. Here we see the charging circuit setup and the digital volt meter. I can now charge the whole battery bank at 12.6 volts with the 3 cell setup. I had to add a fan to the voltage charge regulator. I used 3 -10 amp diodes in the charge circuit so there is no back feed from battery bank. The batteries are labeled as 3000 mah. I will assume 2000 and if that is used for the math at 3.7 volts that is 7.4 watt hours. That would make this unit an 1100 watt hour unit. 1.1 kwh COOL! This can run a tv for weather information, or news, with some lighting with no problem. So this will charge at 300 watts with any voltage over about 15 VDC input. This will handle up to 40 volts input. I can use this for portable power on my land where cords won't reach or, whatever I need some portable power for...fishing and camping etc.

This is how I make shelf stable butter so I do not need to rely on refrigeration. Ghee, or clarified butter costs about $8 per container. I can make 4 containers for just a few bucks. I may over stir just a bit but it works for me to help keep it from burning. I do wait for it to cool down so I can just touch the jar, then I lock down the rings so it will pull a bit of vacuum when it cools. I understand it is healthier for you than having all the sugars and milk solids in it. I really think it should cook for 25 to 30 minutes, or just a bit more even sometimes. It seems different with different brands or weather/humidity might play a part too. Regardless, there is a small bubble frothy foam at first, then in about 10-15 minutes, it changes to bigger bubbles so you know its working if you see that, and it will clear up like a light color oil under the foam when it is done. This has no shelf life limit! Just keep it in a cooler and darker place, like under a counter or in a pantry.

I had some old glass that I used to make a solar air heater. The downspouts cost about $9 a piece so with tax about $40 for 4 tubes cut in half. The AC insulated vent tubing to run from house to the heater cost $27 for 25 feet. The rest of the wood I had on hand. I used 3/8" OSB and its ok but not for the baffle section...I should have used plywood..but it will be just fine like this. I cracked the glass when it was in the sun for a while and then I turned on the fan to test it. The cold air blast caused the crack. It should never happen again since the fan comes on while it is just starting to heat up now. I used an old 12 volt computer fan for air circulation. I added two cutoff tubes at top and bottom to add a bit more heat. The thermal images at the end show first, two pictures of temperature in open air with no glass on it yet. Next two are of first warm-up at 9:30 am with outside temp of 60 degrees. The first is out going from the house, then the input to house from heater after fan started running. The next picture is at input from heater, about 10AM and 62 degrees outside. Then at 11am nd 64 outside temp. The last one is from about 12:30 and 67 degrees outside temp. It really blows some ice hot air, and a nice breeze too. It IS VERY worth making one of these !!!

A clean up of the 413 Coleman camp stove. This is much bigger that the 425 style. This is not to restore to like new condition, just to make it nicer and last longer. It is nice to know it will work at a moments notice. What a great find at the flea market for $5.00! This would make a great survival stove and with a steel box on top, it would be a good oven for bread.

I got this from an e-sales company. The cost was $150 with tax and shipping. I was viewing this, melting things, with some shaded safety glasses...I think the shade was maybe a #3, not 5, like I said in video. These generators are advertised for melting the edges of plexiglass for artistic work, making the edge clear from saw marks, etc. I was supposed to use a solution of 15% LYE. I would then have to use 150 grams of lye for 1 liter of distilled water. I only used 100 grams. I like the amps and resulting flame right there. So I will just run it like this, I believe. No sense pushing the power supply, I feel. This is way more efficient than the one I made. I was running 12 volts at 80 amps with a smaller flame. I love this thing. I am only hooking up the red gas hose on my torch, the green hose has nothing on it. And as a bonus I can use it to make hydrogen rich water for health...so that is a subject all it's own. This will weld or solder or braze aluminum, copper, stainless steel...etc, with a very clean flame. There is ZERO carbon in water, so no CO2 or CO or any soot from flame. The only by product of burning this fuel is water. Yes, fuel from water will save me a lot of money from having to buy any butane and propane, and acetylene from now on. This is "brown's gas"... hydrogen and oxygen both, are sent to torch head mixed together. Melts rocks too...so cool! Just another scrap of NON-dependence !!!

Please be aware that these acids and chemicals need extra caution when working with. Put this in a plastic sink basin or something that can contain a spill if it would happen. So do this ONLY if you are sure you can handle this. I found this recipe from a Robert Smith. I used 5 grams of copper carbonate and 50 grams of 75% phosphoric acid. This can react with a lot of foam if you mix it too fast. Use safety eye wear and rubber gloves for sure. This is not critical on the weights, just close is fine. I had 5.1 grams and 50.05 I believe, so don't panic...close is fine. Clean your metal with sand paper and or scotch bright like pads, and use acetone or the like, to get rid of all oils, before you solder. Having these skills can get you out of a jam when you need to repair things or build with stainless steel. Welding stainless is useful but if you just need to contain something liquid for low temperatures, this will work all day long. Good luck!! And ... good safety !!!

Just a quick video of a simple add-on for old radio test equipment. You CAN NOT use an LED on AC voltage. I am using a 12 volt DC LED, that can be purchased almost anywhere on line. Just doing what I do. Always use a diode with a greater voltage rating than what you are hooking it too, and the same goes for the capacitor voltage especially! DC capacitors tend to explode if they are subjected to AC voltage or under rated for the voltage applied.

I had a box of 26800 Li-Ion 6800 mah batteries for this project. I bought them at $5.00 each direct from the manufacturer in another country. That included shipping. I, of course, tested them when I got them. Yes, I have an appropriate tester for these kinds of batteries. Man I am so happy with the results. 42 batteries in this power bank. The UPS was a dumpster dive. Since I used 7 cells, the voltage is added at 4.2 volts per cell as the charging voltage which is 29.4 volts maximum charge voltage. This unit was set up to charge two 12 volt lead acid batteries, and had a maximum voltage of 27.4 volts into the battery bank. So that is why the voltage is 27.4 volts when fully charged. Therefore, I did not need to add any components to alter the charge voltage or run voltage. This is well worth the cost and effort to do, in my opinion. These 'uninterruptable power supplies ' are well built and cool running. I love having it switch automatically when power goes out...not even a blink in service. They do not need an internal fan. They are quiet running because it has no fan. I have other videos on building battery banks like this.

A totally useless wheel barrow, turned into a useful tool again. These used to cost about $35 plus tax for the cheapest model. So you can save yourself $40 or more, plus a round trip in the truck to town, by fixing it. I used some salvaged wood from the throw away strapping boards used to transport lumber. You may be able to find these from a lumber store when they un-strap the bundles of lumber, for free. I keep a stack of these at all times here. Is it a perfect job? ... no. It doesn't have to be perfect to be able to work again for years. Although I will say, the new handles are much easier to use because of the curve in it now. I did have to counter sink the bolts for the wheel mounts because the "new" wood was a bit thicker than the original wood. I used the old wood to place my new drill holes. Total time to fix this was about two hours. I just got a free wheel barrow.
