RE: https://mastodon.social/@iFixit/116755674669127290

I think this is hilarious. I run a very small scale electronics buisness in the US and all of the new tariffs really hit me hard. I've searched high and low, and the ONLY electronic component that I've been able to find from a domestic manufacturer that is competitively priced is whole rolls of surface mount resistors. Everything else, I order from China. The tariff is usually about 33%, give or take. Nobody from china ever offers to pay it. I guess the makers of this phone couldn't find domestic parts either.

One of the most annoying things in #electronics: you can run a trace under a 0603 resistor, but you can't do that under a 0603 capacitor. The IPC footprints are slightly different, taking the height of the capacitor body into account.

It seems to me to make intuitive sense that electrons would not easily move from p-type semiconductor to n-type semiconductor.

After all, the n-type already has an excess, and the p-type has a deficit.

So you must REALLY FLOOD the p-type with electrons, before the current spills over.

This would be the breakdown voltage of the diode.

Does this make sense?

This is one of my circuit board beetles. The beetle is a custom made circuit board that I designed. Actually, it's 4 different circuit boards, including the wings that are made from flexible kapton circuit board material. Inside the beetle is a 555 timer oscillator circuit that fades the LED on and off, like it's breathing. The eyeballs are USSR vintage AL310A red LEDs. The circuit board in the background was a scrap board from a really old tape drive, and the frame is made from recycled pallet wood.
@alpenglow Thanks Carrie! You're too kind! I'm all in on this Mastodon platform, it's cool.

Here's what I'm working on today. It's a tree that looks like it grew from circuit board traces. It starts with a solid block of walnut. I machine the tree out, pour epoxy into the hole, sand it and stain it, and put an LED backlight in the back.

I've always been fascinated by the idea of the singularity and what the world will look like as the line between nature and technology eventually gets blurred and disappears. This piece is one of my many interpretations of that idea.

I made this guy from metal oxide varistors, also known as surge suppressors. It's a murder hornet. The inside is a wire frame and it's all soldered together with #electronics solder. The wings are made of flexible kapton circuit board. There's also a cool old gold plated EPROM chip on the hornet's back. I have many more sculptures like this that I'll be sharing here in the coming weeks. Follow me to see more!
@gloriouscow I'd assemble the first one yourself, then have them assemble a batch. I've found that no matter what, I've ALWAYS got a bug of some sort in the first board.
