RasmusB on Hackaday.io is resurrecting a Psion Series 5 PDA:

Psioπ

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:

USB keyboard adapter for Psion Series 5 keyboards

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:

Building an ATmega328 uploader

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:

Arduino Pro Trinket – bubble display

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

Max.K designed this low-power, Arduino-based smartwatch:

Chronio

Arduino-based 3D-printed Watch. By not including fancy Wifi and BLE connectivity, it gets several months of run time out of a 160mAh button cell. The display is an always-on 96×96 pixel Sharp Memory LCD.
