episode 39: crossing borders, intensity curves and anti-theft socks

CBA Podcast

4.5 months is still not enough to make you forget this podcast, is it? (And also, sorry about the long gap.)

Another mixed bag as usual. 2 meetups with the CBA Quality Team for some Quality Time.

Eindhoven Hackerspace Hackalot moved to a new location, and I put some LED decorative stuff there, making use of a light intensity curve for a better visual result.

Furthermore, a trip down memory lane with an old elevator mock-up project, tests with 2 potting-materials, a hot glue meltdown, and taking a look inside an older anti-theft clothes tag.

• video of Weekend Of Science (Weekend van de Wetenschap) solder-yourself kit
• video of LED-effect at Hackalot hackerspace (Eindhoven, NL)
• video of an old elevator mock-up project
• random info about perceived vs measured light intensity
• the polyurethane potting compound I used for waterproofing
• RetroChallenge 2019/10

Inside the anti-theft tag:

At the bottom right is the mechanical lock. A pin is locked inside the brass-coloured cylinder by metal balls. Applying magnetic force will unlock it (although I didn't try here).

No RFID with this one, just an LC tank circuit. I think these were similar tags they already used when I was a tiny kid.
