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

episode 38: LEDstrip fun, rand, and voltage drops
CBA Podcast
Hi there! Thanks for tuning in (or reading this text and then deciding not to tune in at all). Another episode with a mixed bag of semi-interesting topics. Thanks for the feedback - the inter-segment jingle will be a bit less loud from now on. Poor ears. We start off by counting pass & fail on this year's new year's resolutions, followed by mentioning a small inline PCB for driving LED-strips and so on. The PCB was used for 2 light effects so far - links to videos of both are given below. Ran into a "gotcha" when dealing with LED-effects: intelligent LEDs stuck in "full brightness"...

episode 37: past events, lasercutting and fear of breaking the rope
CBA Podcast
You thought that we finally learned from our mistakes and abandoned this podcast, and you thought wrong. Once again it's time to lower your standards, and enjoy a new episode of the CBA Podcast. We start with some PCB failures and flaws, followed by a very brief review of the Hackalot lasercutter & vinylcutter workshop. We attended T-DOSE, which is a Dutch open source event hosted in Eindhoven. Then for something slightly out of the ordinary, we talk about back-of-envelope calculations about whether a climbing-rope can actually break if I fall. (Spoiler alert: it cannot.) Some...

episode 36: triple screw-up, LED lamp biopsy and bodyfat measurement
CBA Podcast
After more than 1 month of laziness, let's kickstart this episode with some failures and apologies. Next up is a summary of Hackalot's part in the Open Hackerspace Day 2019, and a teardown of a cheap and somewhat boring Aldi 230 Vac LED lamp. Finally, some very-voodoo and somewhat-less-voodoo methods of measuring the percentage of bodyfat in humans are briefly discussed.
info_outlineAfter 5 weeks or so, we're finally back! You'd think this episode is filled with 5 weeks worth of exciting techie stuff, but don't get your hopes up yet. Because it's not.
Domen joins in to talk about his experiments with home automation, and a sowing exhibition lacking electronics and software. Furthermore, we talk about a disco LED box hack, and briefly list the difference between WS2812 and WS2813 intelligent LED.
