oh wow i hear there's a new development board from a hobby electronics company, and apparently they did their own custom chip! it even has multiple CPU cores!

can't remember what it's called but the name starts with a "p"

anyway it's cool because this has never been done before, it's totally new!

some people are wondering why the flash is external. well, the RP2040 is probably made on a process that does not have embedded flash. this saves a lot of money! a flash process has >25 financial moves added compared with the base process.

financial move: a semiconductor processing step that costs money. could be a diffusion, a mask/etch/strip, metal deposition, or whatever.

i ought to do a whole separate thread on the chip stuff...

why are chips often so expensive? how do chip companies determine the prices of their chips? a thread... 🧵

first thing chip companies do is to figure out the COGS - cost of goods sold. this is how much it costs them to produce a chip--not counting profit or anything else.

but before we can calculate that, we need to know The Life of a Chip, start to finish!

do you watch YouTube? i have a suggestion for you... 🧵

don't give in to the tyranny of The Algorithm, and don't let it choose which videos you watch.

here's a few things you can do:
✅no autoplay
✅run adblock/script block (ad networks often run malicious javascript!)
✅subscribe to YouTubers whose content you enjoy
✅click Subscriptions, and only watch that. no home page, no trending, no "up next"
✅support them on Patreon

there's a tiny round circuit board underneath the sealed part of it! but i want to get to the LEDs.

OK, wow, that bulb made a loud pop when i cracked it open with the help of concrete and a screwdriver.

ever have a hard time finding NE558 quad timer chips? i have a solution for you!

it's a tiny circuit board with four NE555 timer chips mounted on it along with 16 tiny pins so that it can be plugged into a DIP socket.

here it is in one of my Snark Barker sound cards.

here's an unusual vacuum tube! it almost looks like the truncated neck of a CRT, but there are some important differences... 🧵

for one thing, it's a bit larger, and the "electron gun" seems to be quite heavy duty. there's also a metal cylinder right in front of it. what's going on?
