Update

For the record (no one seems to read this anyways):

• I managed to produce high-resolution double-sided PCBs with solder resist mask.
• The Pill Reminder got a redesign using SMD parts and the hardware has been built. The PCB fits behind the pill box now.
• I got a workshop and therefore more space. Currently I am building a workbench. The landlord needs to fix electricity, though.
• I am still after that cyborg thing. I already got the most important parts and some basic tests went well.

More posts (including pictures and videos) are about to come when I got electricity in the workshop.
