I love that I can just think of something, decide to do it, and a bit of time and money later, that thing exists

@karb maybe! It really depends on the project x3

I have been reminded again that not everyone knows about the difference between old tantalum capacitors and modern tantalum polymer capacitors.

the whole "tantalum capacitors catch fire" thing occurs due to oxygen production at internal fissure boundaries in the dielectric during breakdown when exposed to overvoltage. heat + oxygen = fire.

tantalum polymer dielectrics absorb oxygen at fissure boundaries instead of producing it, self-healing them against this effect. no fire.

@cato@chaos.social avatar

@gsuberland interesting. We had a catastrophic failure at a customer caused by a tantalum shorting and blowing up. Looking at the datasheet (it's a Vishay Tantamount series cap), nowhere does it mention "polymer", even though Vishay is a pretty big manufacturer... I guess we should look around for safer alternatives

cato,
@cato@chaos.social avatar

@gsuberland the caps were new, but I think I misunderstood, thinking that tant-poly would not fail short. I just remember those tantalum caps we are using failing pretty violently if they do fail, but then again, no idea if all I've seen so far were actually tant-poly and the older ones would be even more violent?

cato,
@cato@chaos.social avatar

@gsuberland hmmmm right, probably plain old tantalum then haha

I saw an ambulance on the road the other day that had its lights on continuously instead of flashing. It confused the heck out of me, I didn't even know that was possible!
There is a small chance that it was something else (it was dark and I only saw it passing by like hundred meters away), but the shape, hue and intensity of the light sure looked like an ambulance 🤔

cato,
@cato@chaos.social avatar

@xor ah! I do CANopen stuff at work and I came across CiA 447, wondering if that was actually being used widely, so nice to hear that at least some of those lights use it. But yeah, feels weird. I am not sure, but I think it was flashing shortly before it went solid, but I'm sure there isn't just one controller for all the lights that could crash or hang? 🤔

cato,
@cato@chaos.social avatar

@xor interesting! :D oh well, I guess it was just some weird occurrence

jesus christ telegram

cato,
@cato@chaos.social avatar

okay so Telegram made a blog post featuring the following:

  • A group called "Flat Earth Forum"
  • Tucker Carlson
  • The number 1488 (neonazi dogwhistle), later changed to 1391 (a year in which an antisemitic pogrom took place)
  • The date 4/20 (might be a weed joke or might be Hitler's birthday)

seems awfully hard to believe this is a coincidence

I ordered acrylic plates in the hopes that I could have them today and take them to my bf to laser-cut. The shop sent the shipping confirmation on Wednesday evening, so I expected it to either already be handed over to DHL or get picked up on Thursday, so I would have it today, but it seems they only just now picked it up... why send the shipping confirmation so early then 🙃

cato,
@cato@chaos.social avatar

But luckily it's not a big problem. I'll just head over to @schaffenburg on Tuesday then, with the added bonus of seeing some nice people :3

Also, my old credit card, which was discontinued, has been in a weird limbo state for a few weeks now. I had an expense shortly before the cancellation date, but it only got booked after that date. Now my third-party banking app says the card is at zero while the official app says the card is deactivated but it says I have -72.69€ available. I hope they don't come around the corner with a demand note in a few months lmao

@lunareclipse yeah even though they have no basis to claim fees, I sent them a message out of courtesy

My new credit card has a cashback program and I absolutely hate how they implemented it. It subtracts the cashback directly from every expense, which fucks with my expenses tracking. When I buy something and pay with the card, I usually enter the expense right away, but then I look at the transactions and of course it actually cost less due to the cashback. I wish they would just bundle the cashback and transfer it once per month...

cato,
@cato@chaos.social avatar

@karb I used to have the Amazon VISA card and they offered a similar contract with Berliner Sparkasse so I just went with that because I didn't wanna spend too much time on looking for alternatives tbh ^^''

I wonder if in the future, furry stuff will be normalised such that they attribute inventions or discoveries to the fursona.

And I don't mean things like "John Doe who discovered the unifying theory of physics has a dog fursona", but more like "Blue Pupperton discovered the unifying theory of physics".

Like idk, some furry philosopher who writes down some interesting theory just like how we refer to Plato or Aristotle today.

cato,
@cato@chaos.social avatar

@AlgorithmWolf weren't Plato and Aristotle their actual names back then?

cato,
@cato@chaos.social avatar

@AlgorithmWolf do you mean that the names Plato and Aristotle have become so normalized that we don't even know if they did have a different name?

cato,

@AlgorithmWolf hmm right, I see, yeah that'd be awesome

Was visiting friends yesterday and they showed me two card games they had bought on their trip to the US. My initial thoughts were - as always - "ughhh I hope they don't want me to play with them", because I have this weird initial dislike for most board/card games. They did want to play though, so I went with it, and of course - it's ALWAYS like this - it was fun and I had a good time. I really need to be pushed over the edge first apparently

cato,
@cato@chaos.social avatar

That initial dislike feeling was heightened when they mentioned that the game they wanted to play was a deck-building game, but it turns out I apparently just had the wrong idea in mind. :D (the game in question was "Here to slay")

Just got a spontaneous idea for a nice thing for ... let's see if this can become reality

cato,
@cato@chaos.social avatar

So far, already spent nearly 450€ on this project... this happens every time :D

But it's going to be good. Here's some of the parts involved 👀 (the train display in the back is not a part of it though)

cato,
@cato@chaos.social avatar

@Karb_Derg
50m of addressable RGB LED strip - 100€
600W power supply - 50€
Wood, mounting brackets, latches etc. - 195€
Power jack - 20€
Acrylic plates - 50€

More like 415€, I accidentally added something unrelated to the calculation :D

Then I still gotta pay for an milling bit and probably for a painter to properly paint it the way I want 🙃

@cato@chaos.social avatar

Visited a friend yesterday to do some CNC routing on the front board :3 the result looks great, but I'm not gonna show it, I don't wanna spoil it just yet :>

Gonna laser-cut some more parts this evening, excited to see how it'll turn out. I also bought supplies yesterday for painting the thing, which I'm probably gonna start doing tomorrow.

Today, my lawn tractor seat arrived and I mounted it to my kart. It's really nicely cushioned and dampened and despite being way too large, you can drive comfortably. You just shouldn't go fast, otherwise you'll fall over.

I'll keep the seats swappable, so I can use this seat for e.g. camping events, to drive slowly across uneven fields, and use the classic seat for going fast :D

The entire Kettcar. Instead of the regular hard plastic seat, it has a big, yellow lawn tractor seat.

cato,
@cato@chaos.social avatar

This should be acceptable in practice, since the 50ms Tx interval is still pretty quick compared to the possible speed change of the kart. (if the speed changes significantly within 50ms, you have other problems)

cato,
@cato@chaos.social avatar

@garfieldairlines :D yes!

@garfieldairlines what a nice decorative sticker, I sure hope nothing bad will happen to it
