Finished “A canticle for Lebowiz”, the ending was tough, and for some reason i decided to listen Endless Nights by Agatha Christie, and wow, talks about double whammy, both were very bleak…
I have a macropad8, it’s nothing special, it works, the provided “case” is somewhat lacking (just two sheets of lasered acrylic with spacers), but there are 3d models for better ones online.
I appreciate the fact that everything they do is released as open hardware though!
Oh, and I just head about the fork that reached 1.0 recently. Not that I use it or Zed in the first place, but I’m glad people have options to escape enshittification!
Uh that is unfortunate :/ battery protection circuits do not usually care about capacity directly, but just about max currents (which is usually related to capacity), so… unless you need a lot of current, get a 2A limiter and you should be good.
Try not to short anything else, like the battery terminals though! It may weld stuff into a continuous short and start a fire.
That looks like a battery protection PCB, yeah. It usually does three things:
over voltage protection
undervoltage protection
overcurrent protection
reverse polarity protection
Bypassing it would be a bad idea, but it’s also pretty rare they fail. Maybe it’s just in undervoltage protection mode. Try to hook up your variable power supply with 4.2V and a 50-100mA current limit to the battery tabs (check polarity!) and see if the cell takes current. Above 3.6V the battery protection should lift and you should see voltage on the battery output terminals.
Back to classics: I’m listening to “The moon is a harsh mistress” by Heinlein. After that I’ll go back to the Terry Pratchett saga, which definitely scratches the Douglas Adams itch
With displays like these, it’s either parallel or SPI. Try to find a chip in the kapton circuit, that is the actual display driver.
Try to find out the FPC pinout, there should be two pins for backlight, find out of there’s any GND, etc… my gut says this is some kind of SPI based controller, 24 pins is too little for a parallel one.
