episode 43: DMM probes, laundry fix and light-hangout

CBA Podcast

Welcome to a pretty boring episode - just as you're used to by now!

Prepare yourself for epic or less epic talk about a mains test jig that proved very useful, some awesome Probe Master DMM probes well worth the money, and both me and occasional cohost Domen fixing household stuff, and the subtle psychology of starting a repair.

Homebrew-wise, the only thing I made was a smooth green LED under-plant decoration. For fun, I visited an informal light-art hangout and talked about adding DMX512 to my VGA generator board.

Relevant links:

• a potato quality animated GIF of the green plant-decoration LED thing (on Twitter)
• the Probe Master DMM probes that I got - they are excellent
• Wikipedia's entry on DMX512 stage-gear control network

Pics of things discussed:

The test-jig from episode 41.

Clumsily made LED strip using paper, glue and cursewords...

...and a simple PWM/MOSFET driver to control 3 such strips.

Let there be Light, and let there be a Plant!

Domen's epic Fireplace Fix: worn out film cap.
