Hi, and welcome.

 

This attempts to be a free-form, (sometimes) co-hosted podcast about tech-oriented hobby-projects. Do not proceed if you're looking for a high-quality production. However, if you enjoy friendly chatter, read on.

 

On a semi-weekly basis, Michai talks about software, electronics and mechanical engineering from a hands-on point of view. Most of the time, that means giving excuses for not having done any work at all.

Lots of little topics this time, woven together by clever commentary. That's CBA Podcast for you. In the spotlight this time: a shout-out to the Quality Team behind this podcast, impressions from the recent Eindhoven Maker Faire, HCC Retro and Bonami Homecomputer visits, a look back at the current (finished?) RetroChallenge, how to learn Ruby, a DIY portable voltage-reference, the Open Bench Logic Sniffer USB logic analyser, and fun with my angle grinder.

Relevant links to the above:
