So I need the exact specs of the original one to find a spare one. :-/

Touch is working so far !! :slight_smile:

And by the way this project is one for a contest in Germany called "JugendForscht ", a contest for science loving young people. I also have to write a domcumentation and make presentation for this :slight_smile:

If anyone is interessted to get a PCB or the hole thing soldered up, please tell me. You can get it for the costs of materials and shipping :slight_smile:

I think it would be great to have one for the Austrian Fairphoners to show it to other people! What do you think @Stefan @paulakreuzer @werner_noebauer @EvaS?
But how much would it cost?

PCB costs about 10 € (Aisler), Atmega32u4 about 5€ (conrad) + caps and resistors + shipping => about 20€ ? :thinking:

That’s great work! Now with the released cover files you can easily create a fitting cover!

Great work! I enjoy following this development. :smiley:

I hope that the #communityportal will soon be able to promote these #hardware:diy hacks. Maybe you can even team up with @jayy and build a proper 3D-printed case for the QI charger extension.

Hey Cherry,
this project is really cool! If I would have a FP2, I would order one module from you, but I am still on FP1 :wink:
