i will take my emotional support rectangle (object i refuse to describe for now until i can reveal the truth) to the big soft rectangle (bed)

given the price of ram in today’s economy I am sort of wondering about picking up a dead no boot pi4 and transplanting parts across from the 8gb one until it boots. or emailing rpi foundation to see if they can suggest which parts went in the places where parts are now not. it’s mostly passives but a bunch do look load bearing from a quick eyeball of the circuit. I guess I could desolder some from the working pi and test them to get values, but they’re 0201, breathe near them and they are lost. I would need a good microscope too, but I think I have some chance of replacing some of the damaged pads. I guess I could always move the ram from the 8gb to 2gb one too. But I figure two working Pi is better than 1 working pi with the chance of 0 working pi…

Today I went through a pile of dead raspberry pis and did some triage on them.

Today’s subjects:

• rpi4,8g: damaged beyond current repair capabilities. missing parts, a wlcsp shattered, need to research the missing parts to see if there’s any chance.
• rpi4,2g: replaced missing oscillators, functioning again after eeprom recovery
• rpi3a(1): tested ok but seems to have larger than expected voltage drop after usb
• rpi3a(2): same as above
• rpi3a(3): tvs diode after usb seems bubbled - it flickers my usb lamp a lot during boot and gets very hot. lifted the failed TVS, no more extreme heat, but no sign of life. may replace PMIC, whatever hurt the TVS probably hurt the PMIC too. I have a few spare. They’ll need programming.
• rpi3a(4): PMIC missing, but I won’t do hot air work today.

well, I have three more “maybe working” rpi than I expected. I’ll take it.

I have the “I will make something” itch sans much direction

@diffractie@glitterkitten.co.uk I don’t know if anyone’s sent this yet becuase I don’t see much from my little instance, but there’s a photography book called fauxliage about fake plant shaped mobile infrastructure that I really enjoyed: https://atelierlemay.com/fauxliage/index.html

Has anyone figured out the login bypass for the 15C Enterprise yet?

credit card sized px-16c clone !

only one mistake on my pcb, i forgot to route RST to the tagconnect on the back. but easily solved with magnet wire. it’s alive !

@alifeee @solderandchaos my brain went 'right hand circular polarised helical antenna' at first

yooooooo how did i not know THESE exist omg ?!!!
