Rub the plastic cover with fine sandpaper.
HI, would it not be possible to make a simple voltage regulator cut off circuit with a zener diode and a mosfet on the supercaps that would switch the batteries charging it on once it falls below a certain voltage and then turn off when it hits its limit?
This way you could have a power source with the battery for energy storage and supercaps for power delivery all the time if you have something that needs high surge current for short periods.
With those black croc clips that slip just put a drop of super glue on the lever arm on the croc clip. Slide the silicon sleeve over quickly and that will solve all your problems. Hope that helps.
Great video as always Julian 👍
Muppet ready for launch, was as excited watching this as seeing the first moon landing, or exciting episode of original star trek. Hey jim the mosfet is on full power, the di-lithium crystals cant take the strain captain. Give it all the power we have got Scottie, Captain the mosfets are white hot and they are going to blow.
Sitting on the edge of my seat or what!
i have learnt a lot here, that my multimeter is right and the solar charge controller is wrong? multimeter said 15V charge controller shows 12V
same problem with the alligator clips, i cut a cris-cross pattern onto the metal-clip – top and bottom. i suppose filing/sanding could also work
I have experienced the same problem with those slippery insulated clips. They're maddening to use but is there a better inexpensive alternative?
Yes, it seems to be an issue with the clips that are coated in chineseium…
power source -> power sink
Remove capacitor between atmega Reset pin and DTR pin of COM port chip on Arduino board. This will fix atmega restart on usb plug.
My goal before I croak is to make a surface-mount 'MuPPeT', about the size of a postage stamp. I did some 'work experience' for an environmental measuring company a couple of years back (still friends with all of them). They stick their machines in the middle of very cold, remote places (think Siberia here…) – hence lead-acid batteries – charged by a 10W solar cell. But they rely on the battery to supply all winter, when up here (North Finland) there is precious little sun. They charge the battery DIRECT from the panel, and wonder why they are seeing 18V on the 12V battery, and they have to replace them every year in the summer when they can get to the site, at great expense!! A 'MuPPeT' would solve their problem, augmented by a Joules Thief when it gets pretty dark. It needs – averaged over a day – only about 1-2mA .
Was that light running just to extend the time of the video ?
