Making an extension-PCB with capacitive buttons for FP2

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:

Anyone interessted to get a cap. touch PCB ? :slight_smile:
Code is fully working and touch is working smoothly :slight_smile:
Everything soldered up: 30 € (includes shipping)
With 3d-printed case: 35 € ( includes shipping, support not removed)

Text me if you want one and better be fast it’s the last one I have :slight_smile:

Hey, I received my parcel today! Thanks @Cherry97! :slight_smile:

It doesn’t work on my FP2 running Lineage OS, but I quickly assembled another FP2 from the austrian fairphoners’ #spareparts stock and there (with standard FP OS) it works neatly. Only after playing with it a bit the phone started to reboot periodically.

I haven’t gotten around to test this much further as I’m currently sick and also I didn’t want to strain the spare parts too much.

But I’ll definitely take it with me to the internal austrian fairphoners meeting in January, so the others can try it there.

I had the same problem with lineage but with normal OS it worked for me :dizzy_face:
I also tested it on my phone :thinking:
Hmm thats strange … :thinking:
I’m 100% sure that the hardware I send you is okey :thinking: maybe the otg-service of the phone is crashing ?
Can you check the log ?

I hope you convalesce!!
