Show overview
The CircuitPython Show has been publishing since 2022, and across the 4 years since has built a catalogue of 72 episodes. That works out to roughly 25 hours of audio in total. Releases follow a monthly cadence, with the show now in its 7th season.
Episodes typically run twenty to thirty-five minutes — most land between 16 min and 25 min — though episode length varies meaningfully from one episode to the next. None of the episodes are flagged explicit by the publisher. It is catalogued as a EN-language Technology show.
The show is actively publishing — the most recent episode landed 1 weeks ago, with 13 episodes already out so far this year. The busiest year was 2022, with 26 episodes published. Published by Paul Cutler.
