i'm super curious about the electronics hobbyist community in China. perhaps a good place to start would be the Chinese equivalent of YouTube, bilibili. bilibili.com 🧡 Image
only problem is that i don't know Chinese. (i really ought to learn one of these days.) good thing there are good translation tools out there. oh yeah and browsers can translate on the fly, so that's nice. Image
ahh there we go, soldering videos! hopefully bilibili has a good recommendation engine that will lead me to more electronics hobby videos. Image
this guy can solder with his feet. Image
the recommendations so far. i uhh think i'm going to start using the phrase "spicy eyes" πŸ˜‚ Image
oooh drag soldering pr0n. the secret, of course, is a good solder mask. Image
25 million views for a video about an electronics assembly line? incredible, absolutely incredible. Image
here's the link if you want to go down the rabbit hole with me. bilibili.com/video/BV1gZ4y1…
it looks like various inspection stages, these boards have already gone through wave soldering. Image
now THIS is some circuit art! 😍

wow, check out this nixie tube clock! bilibili.com/video/BV11h411… Image
there are quite a few reposts of youtube videos as well, interesting. Image
hahahha good to see the comment quality isn't that different though.

"Your complicated facial features cannot conceal your simple IQ." 🀣 Image
bad apple on an oscilloscope screen. this "EE does not lose power" guy (EEδΈζŽ‰η”΅) has a pretty cool channel Image
ε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆε“ˆ
whoops got lost there for a minute
oooh a 555 timer Image
wait 18 million views for a "DIY oscilloscope"
🀯 Image
hmm, it uses a microcontroller that seems to be pretty popular. STC? hmm Image
it's an STC8A8K64S4A12, hmm, 8051 core. Image
welp Image
enhanced with security features. runs a lot faster than a regular 8051. Image
interesting, WD-40 has a contact cleaner product Image
yep, it's a simple oscilloscope using the ADC in the microcontroller. Image
hmm, looks like there are rumors that fab houses will rat you out to Altium if you pirate their software Image
"99se" is referring to Protel 99se. this is the predecessor to Altium Designer. the "99" refers to the fact that this program came out in 1999. yup, more than 20 years ago, and people are still using it.
oh yeah 99se was my gateway drug to Altium.
on a totally unrelated subject, there are some interesting retrocomputing videos as well!

ooh there's a video about an Apple I. but it's from YouTube. ok. Image
and people thought it was just a video about bad apple. but there's this chinese idiom "face painted miserably, legs carved straight" that i am very curious about Image
θ„Έη”»ζƒ¨οΌŒθ…Ώεˆ»ζ­£. "the face is drawn badly but the legs are right" hmm more or less "no that's wrong but the basic idea is correct"
i, too, use my umm large intestine to listen. πŸ€” Image
several chinese friends of mine say that yes, this literally refers to the large intestine and that it is probably some weird slang πŸ˜‚
also the commenter's name is ε°εΈη›˜ε€§η« ι±Ό which means "small suction cup, big octopus" which i'm pretty sure is dirty πŸ˜‚

here's a weird object! it's some kind of foot pedal with an IBM logo. is it for a sewing machine? electronic synthesizer? what do you think? 🧡 Image
it's got a cursed connector! what IS that? Image
amazingly enough, I found something with the mating connector on it! but what is it? Image

hey so remember the world's cutest oscilloscope i picked up last year? i think it's time to fix the probe socket issue.
i printed a new panel insert that has two BNC sockets on it (the original probes would have had captive cables)
the tricky part is that this oscilloscope has a 333K ohm input impedance instead of 1M like umm every other scope on the planet. fortunately someone designed a little conversion circuit...

in honor of Sim Wong Hoo, here's a quick historical review of the Sound Blaster! 🧡
but first we have to go back to their first sound card, the Creative Music System from 1987. (image credit: Bratgoul on Wikipedia)
this card has some special "CMS-301" chips. if you peel back the sticker, they have had their top marks removed. they're actually SAA1099 synthesizer chips made by Philips. Creative wrote music composition software for musicians on the PC.

Tube Time: a 2022 retrospective 🧡
(and stuff you might have missed!) Image
starting things off in january, i found a tube of super old 555 timer chips! i also decapped one of them.
i also started fixing up an old HP 150 computer. it's not PC compatible but it runs MS-DOS--how odd!

today's mini project: fixing this Radius Thunder IV GX daughtercard. it looks fine, but... 🧡 Image
one of the chips has some broken pins! Image
looks like two of the pins got mashed and broke right at the plastic package. Image

on the bench of healing tonight: my coffee grinder which decided to bite the dust. Image
symptoms: i push the start button and the motor just bumps a little bit and stops.
how to take it apart? hmm, i bet there are screws under the rubber feet. Image
