RasmusB on Hackaday.io is resurrecting a Psion Series 5 PDA:
Bringing a Psion Series 5 into this decade by replacing all the important bits.
The completed result will (hopefully) be a portable modern Linux system with all the connectivity options expected in a modern device.
The keyboard adapter board is available on Tindie:
This is an USB interface for Psion series 5 PDA keyboards. Plug in a keyboard and a USB cable, and use it with any modern computer!
The design files and source code are available on GitHub:
Carlos of GlowSaber wrote a great blog post on how we built an AVR programmer shield:
As I learned more about Arduino, I realized that it is possible to redesign the GlowSaber around the ATmega328 chip [..] I designed an Arduino Shield that can be used to burn the bootloader and upload programs to an ATmega328 chip.
Here’s a example of an ATmega328 in a custom board:
cvadillo shared the board on OSH Park:

With 4 of HP QDSP-6064 bubble displays in a drawer I felt ready to do something with them and the “Clocks for Social Good” – call on hackaday.com finally got me going
