God strewth my allergies are suddenly much worse. 22
Innards of an HP 6624A power supply. GPIB stopped working. Guessing this is 5-10 years worth of build up.

You should open a few elementary school computers after 5 years….
Take it outside and grab an electric air blower. A can will not cut it.
So a case of canned air and a shop vac. Agilent in the back ground, power supply?
Strewth.
You should open a 20y old CRT TV which was common in the 90s/early 20s and earlier… This here is quite clean compared to the TVs. I dit this as my Job till 2000 ad still I do some time but rarely (repair)
Not too bad. I can still see individual components on the PCB. 😉
I’ve brought home a few vintage electronics that had mice living in them. Fun times.
Follow up, dust is all that was wrong with it. Vacuumed out the giant dust bunnies, brushed it off with an ESD safe brush, and blew it out, and the GPIB came back. Testament to mid 90s HP industrial build quality I guess.
This is why getting a mask for COVID wasn’t a big deal for me. I already had several 3M respirators for dealing with shit like this and I just started wearing them when going out. I never had to buy masks for COVID because I already had what I needed.
They are also super handy for doing yard work, cleaning with spray chemicals, and doing anything else nasty.
Fucking up your lungs is for life. What’s left of it anyway.
It looks familiar but I cannot place it.
“You got a cooling problem, ma’am?”
That’s why you should clean your PC, even laptop, at least yearly.
Too bad a lot of modern laptops are no longer easily cleanable. This should be considered during design.
I have terrible dust allergy, which forced me to build a water filter for my PC. Basically all exhaust is circled through a replaceable tank with water. It filters the outgoing dust, lowers temperature & moisturizes the air in one go. It requires external AC fan to increase the flow, which is controlled through a simple triac-based circuit hooked up to the PSU ON signal.
You seem to have some electronics in your dust.
That’s when I put it in the grass and hit it with the leafblower
It’s things like this that make me wonder if electronics are dishwasher-safe.
That thing is so old, the Flintstones threw it away.
Jesus. Christ, might as well just get a new… whatever that is.
Yikes! That thing is filled with RIFA capacitors. Ticking time bombs man. Old HP gear is great but their RIFA capacitors are only good for about 20 years before they start spontaneously burning up.
Seriously, replace them. I see at least five. You do not want to wake up to the smell of burning RIFA electrolyte and circuit boards.
“God strewth my allergies”
I ran it through Bing AI images, and here’s the result!

more or less the same as in my laptop lol
Yeah, this is why I keep a bottle of nasonex in my kit bag with my snips and crimper. Oh, and that reminds me to charge my dustbuster.
I can smell and feel that in my nose just feom looking at this picture! Get a good esd safe vacuum and go to town imo
It’s just some insulation
