Surely figuring out home made pcbs is easier than that. Based on things I’ve made that don’t work very well on a breadboard but work better on a pcb, this guy is likely working hard not smart. (I’ve gotten 2 layer homemade pcbs to work before but stopped when pcb fab services became more affordable to hobbyiests)
I mean, if you put in the work to figure all the stuff out when the alternative is to pay $400 for 5 pcbs that take 2 month to get delivered, then yes it is a more viable option. Luckily that’s not the case anymore, but if things so south in China I imagine the only hobbyiest pcbs you can get will be via this method again.
You’ll have to modify or build a heated laminator until it can apply photoresist film perfectly to a sheet of copper clad fr4. The you’ll have to build a uv exposure chamber and a light diffuser (I used a picture frame and a shower curtain). Then put that on a turntable for even light distribution like in a microwave and figure out some way of pressing all the layers together tightly enough so it turns out right and light doesn’t get under the clear stencil you printed the pcb layout to. This will take a lot of trial and error to get right. Then you have to figure all the variables to get it to etch properly through even more trial and error.
Once you have all this stuff figured out, you have to figure out a way to deal with vias. The best way I found was to manually solder a wire or pin for each one and make sure to make them big enough that this can be done by hand. Keep in mind that regular through hole pads won’t be connected on both sides so you need to solder the unused ones for your design to work out.
I wouldn’t go as far as to call this “worth attempting”, especially if you’re trying to make stuff more complicated than an 8 bit computer but for really simple stuff that doesn’t require high precision, super thin traces and lots of vias, it’s not too bad. Simple designs won’t require the same levels of process perfection as trying to make something like an atx motherboard.

While a Trump presidency couldn’t slam the brakes on the E.V. transition, it could throw enough sand in the gears to slow it down. And that might have significant consequences for the fight to stop global warming.
Even if you don’t care about electric cars this is still bullshit. Let them innovate, maybe they’ll make them better and cheaper, then more people will start caring about electric cars.
Ebikes would’ve been great in like 2018 before governments started regulating them to make them not as good. I don’t even know what’s going on these days in ebikes politics but I dismissed them as something I’ll never buy when they started putting remote speed limiters in them. I’ll just peddle myself on a cheapo bike.
I’m installing Debian next time. Arch is OK but it breaks too often and keeping everything working in an Arch installation is a full time job. Void Linux is like Arch but more stable. Voids weakness is that some of the underlying libraries are different (something about multilib and glibc I think) and there are certain Linux programs that can never run in void and you can’t get them. Monodevelop and virtual box for example. I might have to switch to something else soon just because I need this stuff. (yes I know about qemu and bochs, yes I know about compiling basic c# programs via the command line, and all of that is unsuitable for my use case). Void seems to be a great choice as long as you don’t need to use Monodevelop or virtualbox though. It’s great at gaming once you switch to x11.
There’s a good chance Debian will have a harder time playing steam games due to older mesa drivers or something but it might be a necessary tradeoff.
Edit: also, WTF is the font situation in Void Linux? Half my webpages are have some shitty font front the 90s instead of whatever the normal font is and most of my pdfs look weird and can’t be printed because of it. I have just about every single thing in Void repository with the word “font” installed yet I still have to get out my Ubuntu laptop every time I want to print a pdf.
I’ve had a Debian server in my basement for 4 or 5 years. I’ve encountered a total of 2 entire issues the entire time I’ve had that running. One of which was actual bullshit that I’m still pissed about but the other issue I eventually fixed on my own. It has worked well enough that Debian deserves a go at being a daily driver next time I do an os reinstall.
I really really wish I could come up with a command line script way to issue a command that makes the computer reconnect to the wifi without human intervention of any kind, without so much as even a single ui password dialog, but that’s not a distro specific thing. I use iwctl right now, it seems to be the most reliable and I’ve tried them all.
In the past I’ve been able to lose weight by limiting myself to 1 meal a day + exercising but its really terrible that all is what it takes to stop gaining weight. The human body is too goddamn efficient to the point it’s fucking everyone over.
The problem with losing weight the healthy way is this. Go look up how many calories you burn per hour on various types of exercise. Now look at how much calories different food has. That’s a lot of time you have to give up just for exercise. I have a hard time justifying eating lunch for example if I’m going to have to exercise for 2 hours to burn that off. I don’t doubt there are all kinds of good reasons to not attempt to lose weight via restricting food intake but at least it’s passive and it does sometimes work for some people.
Clean the dishes while waiting for your food to cook and then leave the remaining dishes you didn’t clean because you were still using them until the next dish run.
I did nothing but shitpost for the last 4 or so years of my time using reddit. I posted shit just as dumb as putting glue on pizza. I was such a prolific troll that I’m expecting to see something I wrote show up on Google ai some day.
If rather replace a $5 pair of earbuds every year or so than a $30 pair of wireless earbuds that lasts a year if you’re lucky and only works if you remembered to charge them. Also, I hate Bluetooth because its unreliable and a pain in the ass to get stuff to actually connect. It takes 1 entire second to plug an audio cable into an audio port. You can’t beat that.
I would be hesitant to get on a teleporter even if they were proven “safe”. It could be possible that from my point of view, that’ll be the last thing I ever see. But from everyone else’s point of view Im alive and I walked out the other end without breaking a sweat. But this is a different instance of “me”. From my point of view, would I be “dead” forever or would I be able to witness myself going out for drinks later that day?
Maybe it turns out that if you make an exact backup of a brain, reconstruct and restore the biologic equivalent of ram and system registers back to their original state (sort of how operating systems do multitasking), then it all works out. But maybe turning the brain completely off or whatever is enough to put the “system” in an “off” state and when it restarts, it’ll be a new instance. Maybe you don’t remember the part where you stopped existing so it doesn’t matter.
That would likely also destroy the entire indie dev economy. I highly doubt Microsoft would price things in such a way that continues making it viable for small or single person development teams to make profit.
I’m sure the biggest reason they want to buy it is so they can try to put a stop to gaming on Linux. The prospect of putting windows-only anticheat in the steam client and steam runtime probably has Microsoft executives foaming at the mouth.
A long time ago being a centrist or a libertarian just meant you support gun ownership and also weed rather than only one or the other. Seems times have changed.
