CBA Podcast

Release Date: 04/12/2020

episode 45: glucometer, fuel consumption and vacuum cleaner

CBA Podcast

(Michai is too lazy to make shownotes now, check again later. :-)

episode 44: DMX512, ground reference and LED decoration stuff

CBA Podcast

Hi, and an extremely good 2021 to all of you.

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 42: exploding cap, 3D-printing and planet decoration

CBA Podcast

The thrilling tale of 4 months of doing pretty much nothing interesting is coming to a podcast near you today!

episode 41: oversized test-jig, spiky LED ball and knowing your equipment

CBA Podcast

In this time of global turmoil, the CBA Podcast once again proves to be your one-stop source of distraction and meh-grade information.

episode 40: xmas smoothness, deadlifts and resistive load

CBA Podcast

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.

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

CBA Podcast

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

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.

More Episodes

In this time of global turmoil, the CBA Podcast once again proves to be your one-stop source of distraction and meh-grade information.

We start off by a quick list of how to keep busy in a sort of useful way, followed by a short talk about a 230 Vac test-jig and designing for test-jig repairability.

Already mentioned in a previous episode, I finally got around to building a digital driver box consisting of push/pull FET and open-drain drivers for a low-voltage digital input-signal. And that's not the only thing that got finished: I also got around to make mechanics and software for a spiky icicle LED ball decoration thing, which worked out quite well.

A fuzzy talk about getting to know your electronics equipment more intimately concludes this episode. If you are looking for useful things to do there, perhaps this is worth a shot.

some podcasts I listen(ed) to, in random order:
- Eaten By A Grue (Carrington Vanston & Kevin Savetz), about Infocom text adventures (even if you never play(ed) those, like myself)
- DoubleTake (Carrington Vanston & Shari Creamer), where 2 people review 1 mystery movie each
- Henry & Heidi Podcast (Henry Rollins & Heidi May), true stories from the past. Most have to do with music/punkrock, but probably accessible if you're not 100% into that.
- SledgeCast (Gerry something and Iain something), talking about "Sledge Hammer!" TV-episodes, one each episode. I binge-listened to these while driving to Hannover and back.
- The Amp Hour (Dave Jones & Chris Gammell), about electronic engineering. Occasionally have interviews that go off on a tangent, which I like.
- Rationally Speaking (Julia Galef), about the borderlands between reason and nonsense (unquote). For some reason I can't listen to this while driving, but while walking on a treadmill everything's fine. Go figure.
- Damn Interesting Podcasts (Alan Bellows), true stories, told in fitting atmosphere. Creepy. Weird.
- Retro Computing Roundtable (Paul Hagstrom, Earl Evans, Carrington Vanston, Michael Mulhern, etc etc) about retrocomputing
- Welcome to Night Vale (Joseph Fink, Jeffrey Cranor and others), imaginary weird reports about an imaginary desert town. Recommended to me, I like it, haven't heard more than the first few episodes, and as with Rationally Speaking, I can't seem to listen to this while driving. :-)
- Joe Rogan Experience (Joe Rogan and guests). Sit down for an hour or two to get to hear about people you might not even have considered otherwise. Or skip to the next episode, of course.
- You Don't Know Flack (Rob O'Hara), telling stories about his own life. This guy can really tell a story, very funny and entertaining, even if you're not really into the subject at hand.
- Multiple Sadness (Rob O'Hara), about B-movies that are so bad they're good. Very funny and entertaining.
