Not everything in my lab runs in a virtual machine. Some of it has a soldering iron involved. This is where the hardware projects go: things I design and build myself, what I learned along the way, and what I’d do differently.
What also might creep in are electronics repairs, fixes, and builds not related to my home lab or computer systems.
What you’ll find here:
- DIY battery packs: designing a standard pack I can reuse for different projects, and salvaging, testing and sorting 18650 cells from old laptop batteries to build it.
- Safety first: lithium-ion cells store a lot of energy, so every build comes with the checks and precautions I actually use.
- Small builds around the homelab: radios, sensors and other gadgets that don’t fit anywhere else.
The DIY battery pack series picks up where the 2021 design post left off, starting with harvesting the cells in March 2027.
