    Just be careful of these cheap Chineseium gadgets especially the app might try and steal personal data and GPS location lol

    I have same one . How to re program it to handle a more extra little more voltage . It's a 30v and I need 10v more test so it can test 40v

    In case you never found the instructions for the Battery Discharger, hold down the tactile switch and then power up the unit and you'll get two Functions FUN1 and FUN2. Fun2 will log the Wh etc.

    I literally have hundreds of these USB phone chargers. They're free at garage and lawn sales. I glue them together and wire the AC parts together in a case of some kind.

    Hey Julian, did you ever use that 120505S isolator? I'm looking at the same thing but I cant find a video if you made one

    I have been a fan of old Casio watches for many years, and when I find a deal on one, I snatch them up. Here about 2 years ago, I found a Casio Tela-data solar powered watch for a very reasonable price, old stock new in box. Last year, I was wearing her, for probably about the 5th day since I dug her out from my packed back when we were on our Winter escape to Arizona. We stopped in a Denny's truck stop in Kingman Arizona, and enjoyed some of the best damn country fried steak I have ever eaten. When I went to pay, the lovely little lady, perhaps 19 years old and overall about a 9.66 on the gal scale saw my watch. She was amazed that they made a solar powered watch, I explained it was an old watch from a long time back. She said she would love to have one like that, showing me the band watch sort of like the one you have in this video, well with a black strap and perhaps a more expensive model, who can tell now days. She said her husband just gave her that watch and the darn thing must be charged EVERY DAY, such a pain, why don't they just make them like the one I had. She even offered to buy the watch, but I apologized and said it was not for sale, but she took down the make and model of the watch and was going to look for one on Ebay. Some times the old things are just better.

    Just wondering could you perhaps use the 2 five volters one for positive five volts, the other for negative 5 volts, giving you a power supply for an opamp?

  10. Avataaar/Circle Created with python_avatars Daniel Horne says:

    Power supply requirement : DC12V voltage (actual voltage 11-14V) for the 60w load tester in this video

  11. Avataaar/Circle Created with python_avatars Daniel Horne says:

    i got both the lcd 150w and that unit in the video but mine didnt have the stand offs

    That soc is pretty sweet. It's got more available features than a raspberry pi. It's be fun to hack it to do something cool.
