Finally, today a little bag with some pogo-pins arrays arrived from China. Time to make my own USB charger for the tempest. Next step make a design to hold them and 3d print it. To be continued. [pogo]

I have some of those around as well… bought them in '19 thinking of doing the same thing with the SKY… :frowning: never got around to actually making it…

Next step, the basic design is done. Four holes for the pogo pins, and a usb port in the part on the right hand side, and on the left hand side a small column that pushes the pins into place, and a part where I can slide the pcb with the usb port in. Of course that is the theory. Experience tells …

So it can take either USB-A or micro-USB for input?

no, the pcb I used (because I happened to have it), is normally used to charge a lithium battery via the micro-usb, and the charged lithium battery is used to deliver 5V to the usb-A (a.k.a Power bank). In my 3d printed housing the usb-A port is covered up.

apparently the unit can accept 3-5V as a charging voltage (something I just learned today)

Wow - pretty nice looking. About a thousand people likely want to know where to get the board and how long it takes to charge from dead to full, and how many Amps/Watts the charger part is, and the cost etc. And I think it needs to shoot lasers up over the logo when it’s charging :slight_smile:

the board is irrelevant, you could use any usb charger and use it’s 5V directly to make a connection to the pins. I just happened to have this little pcb and it was an easy way to get usb inside. I’m waiting for the unit to drop to 2.39V before I start charging. So I can’t tell. But you could of cou…

Sunny, Great Job on the 3d Parts!
