from CBA Podcast Hosted by Michai Ramakers
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: HCC Retro division meetings in Bilthoven, NL (page in Dutch) Bonami SpelComputer Museum in Zwolle, NL (page in Dutch) RetroChallenge, and my entry for that Rubylearning.com: a readable Ruby tutorial Ruby-doc.org core API reference Open Bench Logic Sniffer USB logic analyser Rigol DS6000-DK demo board for testing scopes/analysers PulseView GUI for this and other capture-devices (manual) Trotec PAGS 10-125 angle grinder (roarrrrrrr!!!)
