As my family's computer guy, my dad complains to me about this. And there's no satisfactory answer I can give him. My mom told me last year she is "done learning new technology" which seems like a fair goal but maybe n

I think everyone builds one of these little camera cars at least once. I made one when I got my NTC CHIP[0] in 2015. This was a pretty big deal at the time because Raspberry Pi were still months away from releasing a model with integrated W

If you're looking at the "how" specifically: This would play MIDI files, not MP3s. Midi files are the digital version of that book with the punched holes, it's a sequence of note events over time. The physical book with

Makes me wonder how many living people on earth have seen a nuclear explosion with their own eyes. It can't be very high, maybe 1-10 thousand? Not a number you would want to see increase, to be sure.

My dad always pronounced it a-luna-min, so my whole life I thought that there were 3 pronunciations, and the fact that there are only two correct ones feels strange to me. Not sure where he got that from, maybe he had special metal from the

Most of them weren't, but some were. If all you were doing was looking at screens of text, a long persistence phosphor could be desirable[0]. I've got one that is inside an Apple II monitor. Can confirm, the image looks very flick

In my eyes it's quite the opposite: there is almost nothing that exists as a complete product on Amazon. Faster and cheaper? Yes. Better and more complete? Not a chance. But you have to want it bad enough, and have enough skill to do

Reminds me of when I first started learning computers, there was a version of Windows 3.11 that fit on a single 1.4M floppy. Some of them fit even more stuff by uncompressing the floppy into a ramdisk. You could even make your own, starting

Our best answer might be film. Some of it has already survived 80 years. (Micro)film is supposed to last something like 500 years, and it's what Github picked for their Arctic Code Vault. I was curious one time so I looked into it, bu

Texas also has a lot of wind power. I was driving though at night one time and there were turbines on either side of the road as far as could be seen. Thing is, they are tall so they have those red airplane warning lights on top - which wou

Your mom was probably thinking along the right lines haha. But don't worry, TV tubes are practically worthless. I've been to swap meets for an antique radio club in my area. Sometimes, there will be a few boxes of tubes from TV se

I continue to be skeptical of text to CAD, because to make it work, you're going to be doing a whole lot of this [0]. This is an extremely high bar to clear to be better than even the most basic of CAD skills. I'd wager that for m

Growing up in the 2000s, I've come to associate blue LEDs with tacky cheap garbage appliances, as no sane manufacturer would treat their customers with such contempt. The brightest LEDs were always in the cheapest, lowest quality stuff

I'm sure part of it is that EE claims probably the widest range out there. You can have kilovolts or microvolts, but mostly the same rules apply. Or you can learn how to power a small sensor for years off one small battery, or how to p

Nobody believes me when I say that soldering SMD with an iron is easier than through hole. You don't have to keep flipping the board over!

I run into this problem so often that I've been experimenting with rendering all the PDF pages to png images first, and a program that loads all of them on screen at once. The upside is that it is extremely fast, there is no loading ti

Wow, I'm clearly behind on my flickering candle LED technology knowledge. Thanks!

To continue this tangent, legend has it that some of those battery powered tea candle lights actually reuse the chip from cheap music playing trinkets. If you replace the yellow LED with a speaker, you might hear beepy christmas music or ha

I came to FreeCad with some years background in Inventor, NX and SolidWorks. The jump from any of these to FreeCAD is not very big; you're doing a lot of the same things. But, most of the problems FreeCad has are solved in those, so yo

Also a good example at how technology has made things slower. An analog TV can change channels mid-frame; try that on a digital TV and you're met with a 0.5 to 1 second delay, just like on this site. It's not much, but it adds up.

I agree, we have Bambus at work, and they are an outright pain to fix compared to my Voron. And things do break. On our new H2D, we had some filment get jammed in the extruder. Fixing it basically entails taking the entire front of the to

Not IP related, but I built a Voron printer a while ago, which is sort of the last word in DIY printers. It's not so much a printer as a parts list and set of instructions, but something that's not lost on me is that most of the c
