Hi, and welcome.

 

This attempts to be a free-form, (mostly un-cohosted) podcast about tech-oriented hobby-projects. Do not proceed if you're looking for a high-quality production.

On a semi-biweekly basis, Michai and optional cohost talk 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.

Another cohostless(tm) episode, talking about assembling and debugging a digital logic PCB using the Rigol DS1054Z's segmented memory ("waveform recording"), the need for an actual logic analyser, possible clipping of silkscreen layer when having PCBs made, DIY PCB-stencils using lasercut removable label-sheets, the Gigatron homebrew TTL-computer, and dual fail getting a LED-driver to work and actually making planned software.
