Open hardware electronics

There are a good number of companies and enthusiasts who produce open hardware designs. These notably include Adafruit, Sparkfun, Olimex MLab Zio Plus a variety of individuals on Tindie , OSHWlab or Kitspace Using electronics typically involves connecting an MCU to various sensors, peripherals or actuators. There are a few standards that try to combine these Read more about Open hardware electronics[…]

Open Source Robotic Processing Unit

Inspired by the ‘proper’ Robotic Processing Unit I was curious what a truly ‘Open’ version of that might look like. The CM4 footprint seems to enable modularity so over on the Twisted Fields forum I did a bit of CM4 module research In 2023 the ‘openness’  always going to be imperfect, RISC-V is going to be Read more about Open Source Robotic Processing Unit[…]

Offline communications in 2018

Disclaimer – this is just some notes to help organise my thoughts. It might be of interest to someone, but it’s not a ‘proper’ blog entry. I’m particularly interested in a peer-to-peer mesh as a network for SSB messages: a decent(ralised) secure gossip platform It works, with a sufficient density of Read more about Offline communications in 2018[…]
