It's not really electronics in the same way that learning to hold a pencil isn't really calligraphy.

Both my parents run on Microsoft Excel. Neither of them care much for phones or tablets, but if there was an ExcelDeck running ExcelOS and it had a web browser and worked like the desktop version of Excel does, maybe they would go for it. A

David of the Usagi Electric youtube channel received an LGP-21 computer (not Mel's LGP-30) a while ago which will become a future channel project. But along with it, he received a binder of LGP-30 code... with a bunch of programs writt

On the '65 beetle we have, I always heard that the main culprit wasn't the fuel lines themselves, but the brass flange for the fuel hose being a (not great) press-fit into the zinc carburetor. And that's after the fuel pump,

This reminds me of burning scrap VW engine blocks or transmission cases. It can be done on an ordinary wood camp fire. You'll probably want to cut up the scrap into more manageable chunks rather than go for the whole thing at once. The

In parallel, learn to modify stuff you don't own so that you do own it.

Hardly. This seems like the opposite alternative, something that has minimal or no mechanical hardware provisions, and few ways to interface with external motors and sensors.

I had a 5A inexplicably develop a crack in the screen literally before my eyes as I was holding it. I watched it propagate from left to right over about 6 seconds. If I hadn't seen it, I would never have believed it. Not even worth arg

I'm afraid we have far more basic problems than that - illiteracy in their fingers. We have people who can't use a knife or scissors, let alone a power tool. 3D printing is an excellent introduction to just making an actual object

To be able to design any manufacturable item, you have to know that a wrench is used to tighten bolts, and a screwdriver must be able to reach the screw. There are people who don't. Some of them graduated engineering school with me.

I know a couple people who are exactly this brand of weird. One of them owns the domain onepartwords.com. The other wrote a one-syllable dictionary. It has about 2500 one-syllable words, defined using only other one-syllable words . Here&#

Side note, but if you're trying to sell off this stuff, you better do it soon. Train nuts like this are a dying breed. Probably will all be mostly worthless in a couple decades, along with commemorative plates, or the "good china&

Reminds me of an estate sale I went to one time. Unassuming place, one of those tiny postwar homes about the same size as the one in this article - but with at least double or triple the density of this train layout in the basement. The own

Early 2000s. My family used VHS until after the switch to digital TV. Not that we would buy one new, but if we found one at a garage sale for a couple bucks we would take it. Used to have a stock of 2 or 3 on hand at a time. They were all l

It's more impressive that Apple was able to do this. Apple had a couple dozen people. Radio Shack had thousands of stores and their own factories. And Apple's computer was better (though more expensive).

The TRS-80 is what a computer would look like if you only had a CB radio factory to build it. I think they designed it to be cheap enough to do that first production run, but then they were stuck with it since it sold so well. When they wen

If you've never FDM 3D printed anything before, you'll probably find it about on par with most other plastic objects in your life, even if it is technically weaker (for the most part). Most things aren't particularly fragile

Altium, Solidworks. Altium is "go and get coffee" slow! Kicad loads in 2 seconds, and FreeCAD in 7 seconds though.

Nice, it took less than a minute to find a PDF of the docs. That's already more seriously "offline" than the alternatives.

You would hardly believe they once made top of the line voltmeters, oscilloscopes, atomic clocks, calculators - even their printers were once the best.

I'm not sure if there's any material limitation to it, but every PETG roll I've used has come out with a very glossy finish, which is probably not what you want here.

One time, I was driving across New Mexico, and we heard something break under the hood. No point in stopping to see what it was; we might as well drive it as far as we can until it stops. All was fine, going along the same perfectly straigh

Normal on anything that has to work outside. Also, hardly an impediment to repair. I've done it myself on a car ECU: open case, scrape off conformal coating, desolder blown IGBT, replace with IGBT salvaged from junkyard unit, spray on
