This website has articles and links to some of my open source software projects, as well as some older endeavours:

  • DoBB

    The "Doodling on breadboards" section has some tricks and ideas to explore electronic circuits on breadboards.

  • JeeH

    JeeH is a hardware abstraction layer and multitasker library for STM’s 32-bit ARM Cortex microcontrollers.

  • Retro

    Various articles about my travels in retrocomputing-land: PDP, Z80, CP/M, BCPL ... that sort of thing.

JeeLabs

This was a daily weblog from 2008 to 2019 about my adventures in Physical Computing and JeeNodes: low-power ATMega's with a built-in ISM radio module for use as a Wireless Sensor Network in and around the house.

"jeelabs.com", "jeelabs.org", and "jeelabs.net" are no more

Those domains are no longer owned by me and as with so many things on the internet ...
... that opens up the floodgates to some fairly idiotic stuff.

A snapshot of the JeeLabs weblog is available at https://jeelabs.wippler.nl. Most links have been updated.

An archived copy of the old JeeLabs site can also be found on the Internet Archive's WayBack Machine.
