Welcome to the holidays, where nostalgic aromas float through the air and remind you of good times #ElectronicsRepair #happyholidays
Working on an #IBM5150 for #DOScember. Following troubleshooting guide on MinusZeroDegrees.net. PSU seems good (stays on when plugged into board), but no beep code from speaker.
Does the T1 Trimmer look ok? It could be broken as mine doesn’t look like the one in photos online.
No obvious damage, no exploding caps, and voltages look good coming off PSU at P8 & P9 connectors.

Probing the hive mind for a gift for my brother. His hobby is refurbishing vintage electronics. I was thinking about a lamp that can be positioned to light up the innards of devices while he's working on them. Does anyone with a similar hobby have any suggestions?

With my impatience being the real issue, I finally popped in my HD DVD copy of Nine Inch Nails Beside You In Time to see its top-level menu.
Again, since I don't have a remote yet, I have no ability to proceed from here.
So, that's the end of this saga until I can emulate the Toshiba HD DVD Player remote (model SE-R0285, I believe). With how slow this player is, I'm not sure this will ever find a permanent home on my shelves. But it's been fun to get explore the inner workings, even if that was totally unnecessary.
The dozens of other owners of this HD DVD player may already be aware of my issue and laughing at me. Reading the manual revealed a hint with this block of "keep your expectations low" wording. The problem isn't hardware at all. Though I'd still argue it shouldn't be as bad as it is. (Why can't I eject the disc until it's fully booted!?)
Hooking it up to a display for the first time, it eventually showed the clock setting page. (The equivalent to blinking 12:00 on an old VCR, I guess.) This page took probably 30 seconds to show up on my TV's HDMI input. At this point, you can finally eject the disc tray.
Of course, since I don't have a remote, I have to skip this.
So, the initial symptom was that it wouldn't eject the disc tray. At the thrift store, first it would just say "Welcome" forever and the eject button just beeps. After unplugging and trying again, the eject button doesn't even beep.
Being me, my first thought was to take it all apart to make sure it doesn't have any obvious physical obstructions. Took it down to being able to see inside the drive, but nothing obvious causing issues (and no free disc this time).
A while ago I got this dead Orange Pi Zero 3 for parts. Turned out to be a dead PMIC+CPU combo. No wonder they sale this exact combo on AliExpress as a replacement parts set 😊.
I bought it and got both chips replaced - it all worked except no matter what I tried it won't output anything over HDMI.
Last night I decided to reball and resolder the CPU - and voila - now I have a fully working board 🏆.

So I ordered more VL805 from #Aliexpress and those turned out to be exactly the same - fake chips that either do not work (do not get detected by Raspberry Pi 4B) or some of those were even shorted out of the box. Wow.
Also the marking on the fake ones gets washed away almost instantly with IPA.

What I really like about @arduino is that even after the merge with #Qualcomm they remain open and true to their vision.
Proof?
Here’s a schematic for the new #ArduinoUnoQ publicly available on their website:

P.S.: how about following this amazing example, #RaspberryPi?

It's funny how these days I find BGA reballing a rather soothing and meditative practice instead of a stress factor it used to seem not so long ago 😊.

As a tool reads the #EEPROM, in a #Circuitboard, power reaches other #ElectronicComponents 🫣!

So, #HapaUjanjaTu, without removing EEPROM off from out of #motherhood, readers introduce voltage changes' ujinga, insufficient voltage, this all f*ks, corrupting the data needed in a chip!

Lately I started to encounter the rare cases of shorted capacitors on Raspberry Pi 5 - and I actually love it, because it's a quick and easy repair 😊.
