Hi, and an extremely good 2021 to all of you.info_outline episode 43: DMM probes, laundry fix and light-hangout
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.info_outline episode 42: exploding cap, 3D-printing and planet decoration
The thrilling tale of 4 months of doing pretty much nothing interesting is coming to a podcast near you today!info_outline episode 41: oversized test-jig, spiky LED ball and knowing your equipment
In this time of global turmoil, the CBA Podcast once again proves to be your one-stop source of distraction and meh-grade information.info_outline episode 40: xmas smoothness, deadlifts and resistive load
Welcome to the first and so far best episode of 2020, the third year of this podcast. Thanks for sticking around and making this happen, or alternatively, thanks for just tuning in - hope you like it.info_outline episode 39: crossing borders, intensity curves and anti-theft socks
Another mixed bag as usual. 2 meetups with the CBA Quality Team for some Quality Time.info_outline episode 38: LEDstrip fun, rand, and voltage drops
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"...info_outline episode 37: past events, lasercutting and fear of breaking the rope
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...info_outline episode 36: triple screw-up, LED lamp biopsy and bodyfat measurement
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_outline episode 35: home sensors, disco LED hack and airplanes
After 5 weeks or so, we're finally back! You'd think that means this episode is filled with 5 weeks worth of exciting techie stuff, but don't get your hopes up yet. Because it's not.info_outline
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.

- 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!
