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
people want to know some of the channels i subscribe to, so here are a few:
12voltvids
adam savage's tested
adrian's digital basement
applied science
bigclivedotcom
cathode ray dude
celgenstudios
curiousmarc
fran blanche
LGR
mitsuru yamada
RMC
shango066
techmoan
8bg
videolabguy
vwestlife
bad obsession motorsport
bandersentv
baumgartner restoration
clickspring
cody'slab
dalibor farny
eric strebel
glasslinger
nurdrage
photonicinduction (plz come back!)
sam zeloof
sampson boat company
smartereveryday
strange parts
tech tangents
the proper people
the signal path
this old tony
traffic signals training
uniservo
and a few other random ones.
you'll notice it's a mix of a few big-name channels as well as some more obscure ones. i really enjoy some of the lesser-known creators.
anyway, in general i don't spend a whole lot of time watching youtube. i find electronics projects to be far more engaging!
i've also got a channel of my own, although there's not a whole lot going on there: youtube.com/user/TubeTimeUS

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!
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!
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?
it's not an electron gun -- this tube uses a penning source with a heated cathode to generate ions instead of electrons.
