oh that was such a pain in the butt. the switches were really hard to clean and the spring action was just never quite right afterwards

what's the weirdest i2c device you can get

flux might help but this could be corrosion from a leaky cap. kinda miserable but the only way i've found to deal with it is scraping. sorry. 😐

aww

did they have ours?

yes, EDAC makes them, but they're expensive

it's just a digital comparator output, so not really all that useful.

i'm expecting to receive 29847538764 replies saying "RUN DOOM ON IT" but most of these MCUs only have around 8K of RAM. you could probably use the NOR flash like RAM but the result would be slow and would wear it out very quickly.

what could you make out of a disposable vape without any hardware changes?

* flappy bird game (one button)
* magic 8 ball (magic "vape" ball?)
* "flute" (using pressure sensor)
* temperature data logger with waveform display
* adjustable battery power supply

some fancy ones also have bluetooth and even a touchscreen! (i haven't reverse-engineered those yet)

a typical vape board has
* cortex M0 MCU
* NOR flash IC
* a pushbutton or slide switch
* li-ion battery + charger
* nice LCD display (sometimes LED)
* differential pressure sensor
* coil driver(s) with voltage feedback

many of these vapes bring the ARM SWD lines out through the charging connector's CC lines. with a simple breakout board and an SWD dongle you can reprogram the firmware.

huh weird, bsky moderation marked your reply as adult content. well, i guess we're both adults. 🤷
