Implementation of the tonuino project: https://www.voss.earth/tonuino/
Parts used:
Important since the original PCB didn't arrive in time a 70x30mm protoboard like this was used: https://www.amazon.it/Basetta-Millefori-Vetronite-piastra-Prototype/dp/B075W1H2TL
Also you may want to use a powerbank that is easier to misuse... I basically cut mine open
After assembly a piece of felt was cut to size and attached via double sided tape, on the felt a stitched cross marks the RFID patch
Update after a couple of months:
The author marked this model as their own original creation. Imported from Thingiverse.
