Opening up a snowball USB microphone.
Fun fact: it's screwed and then TAPED together.
It's apparently an ICE-6327, or a P2FH31497A0
So the main chip is a Cmedia CM6327A, which is a USB Mono ADC with USB interface.
This thing is designed to interface with an external EEPROM to get configuration info like product string and USB VID/PID, or you can have another microcontroller talk to it over i2c
And the other chip is an Atmel 24C02N, which is a 256 byte i2c EEPROM.
The microphone itself has no info on it, but it's held in place with this silicone mount, which has room for two mics
the two pin connector is an LED for the front
Then there's a 5-pin connector which goes to the USB socket on the back. This is the part that's broken on this one, so I'm trying to get it out so I can replace it. So far, no luck.
It's just USB-B
FINALLY
ADVANCED PINOUT DOCUMENTATION
rather than mount a new socket I'm just splicing a spare USB cable
Interesting. It's working, but it's showing up as being from C-Media instead of from Snowball.
I wonder if the EEPROM broke and not just the USB?

Someone should make a compilation of people who did unaware playthroughs of The Outer Wilds and their reaction to what happens about 20 minutes into the game.
This thread will have spoilers when I go and do that
But for now, if you haven't played it, don't look it up. Just go play it. It's an amazing game of space exploration in a small scale
First Materwelonz. They didn't die before. My favorite part is "wait, what's that noise?"

That conspiracy about the vac cine making you magnetic is just the best. I love it, because it's just so left field and nonsense
BTW if you take too many Tylenol/paracetamol it will make your body emit radio waves in the 93.4 mhz range which may interfere with your reception of your favorite heavy metal FM radio station
Be careful doing electrical work if you're on antibiotics because they can cause your body's resistance to drop, which may increase the chance of a dangerous shock

I've argued about this before, damn it! Launching billionaires into the sun is a terrible idea.

It takes way more delta-v to get to the sun than it does to just fling them out into interstellar space!
And the reason is simple: you'd think it'd be easy to fall into the sun, and it is, if you're motionless relative to the sun.

You are very not.
You're already moving at about 30 kilometers a second, sideways, because YOU ARE IN ORBIT OF THE SUN ALREADY

Today I may get to document a previously unknown type of floppy disk.
It's a good day to be a Foone
Ever seen one of these before?
here it is next to an 8" (NOT a 5.25"!) disk
this is officially a Huge Motherfucker of a disk.

I MUST KILL THE PRIME MINISTER
This is software for the videonics DirectED video editing device. The software loads from vhs tapes, and consists of a bunch of flashing black and white rectangles.
I'm only like 90% sure it's not trying to hypnotize me

I think my 3d printer's camera may be misaligned
It just sent me an update saying that the print is done, and included this picture of the final print.
I knew it was a mistake to try to print on the ceiling
