Rasputin201223 | Building a small travel computer.
Rasputin is the name of an ongoing project to build a keyboard only, low power, mobile workstation. It currently is in it's second prototype iteration. The third iteration will hopefully yield a case that can be used in a longer test production phase.
- Raspberry Pi 4B 8GB RAM (85 x 56 x ~20mm)
- 7" Waveshare Display (156.9 x 124.27 x ~15mm)
- Powerbank Green Cell Power Play 10.000 mAh 18W (140 x 72 x 14.1mm)
- EZ Planck Keyboard (233 x 80 x 30mm)
- Transcend RDF5K SD Cardreader USB 3.2 (24 x 56 x 9mm)
- Basetech Plastic Hinges (39 x 30 x 4 mm)
- Joy-it Armor Case BLOCK ACTIVE Heatsink
- DietPi (using Thomasorus guide)
- i3 window manager (config file coming soon)
Mounting the hardware on handcut woodden boards to test size and hardware setup.
The second prototype case was designed in Inscape and modelled in Blender and sent to a wood model store nearby that offers laser cutting services.

The case is not quite ready for a longer test run yet. Some things need to be adapted to make it usable.
- Plywood becomes fragile at this level of detail. Try to use solid wood next time.
- Replace hatched slots with a more stable pattern.
- USB plugs are longer and move less far into the slot than expected
- Reposition Raspberry Pi to better fit USB cables
- Long, skinny screws are hard to come by. Glue more next time and use shorter screws.
- Case top needs to be increased by two layers to fit heatsink block.
Prototype 3 is currently in development.
