In my early 20s I had a part-time job as a pizza delivery driver. When there were no deliveries, I would answer phones or take orders at the counter. One day one of the touchscreen monitors at the counter stopped working. It was just black all the time. So we were told not to use it.

A few days later I was on lunch shift and bored, I was trying random things to see if I could fix the monitor. Switched the inputs, switched to a different VGA cable, etc. At one point I discovered the touch panel was still working, I could interact with the OS, even though nothing was displaying. I was pressing around different areas of the screen and I accidentally found that pressing right in the centre of the screen caused the display to re-appear! It would disappear again after a few seconds. Press that spot again, it came back. I was fascinated by this, I showed some coworkers, they didn’t care.

Over the course of the day it was getting harder to make the display re-appear. It gradually needed to be pressed quite forcefully to come back. I stared using my knuckles to knock sharply on the spot, and that was working.

When my manager arrived for the night shift, I was excited to show him my discovery. I said “hey man, I kinda fixed this monitor, watch this!” And I enthusiastically knocked hard on the centre of the screen with my first. The LCD lit up and showed the display, but at the same time shattered in a rainbow ring the shape of my fist.

The look on my manager’s face was of awe and horror. I was trying to explain what I had meant to do, but I realised what it must’ve looked like to him. “Hey man, watch me fix this monitor!” Before smashing the screen with a swift punch. It wasn’t possible to explain it a way that didn’t sound crazy.

In the end I convinced him that the monitor was faulty anyway, and we were going to replace it anyway, so my accident breaking it more is not a big deal.

An ice tray to cold down a router.

I changed ISP, the new one told me that it would take like a week to send me the credentials to use my own ADSL router 🙄, in the meantime I had to use the cheap-ass one they provided.

The new service crashed like after five minutes of use, after some some back and force with the technical support unsuccessfully I notice that the router was extremely hot when the connection crashed and normal when it started to work again.

It has not any cooling system, and being in the middle of the summer didn’t help either.

So…. I tried to put an ice tray from the freezer on the router and it worked. To be “safe” I put a plastic bag between them to avoid any condensation dripping onto the device.

I have a pixel 8 and had a faulty screen caused by poorly installed latches that held down the screen. Slapping above the power button seemed to fix it for about 20 minutes.

Took an angle grinder to a mini-ITX case to fit a full ATX size board in it.
The board is resting unsecured on an anti-static bag and has a few mm of wiggleroom.
The powersupply is resting, unsecured to anything, on top of the PCIe lanes.
The rear fan is pressed up against the back grill by cables.
The harddrives are just kinda chilling where-ever.
The cables are routed with hopes and dreams.

This is a hypervisor and is the backbone of all my infrastructure.

Shorted the center pin of a transistor in the numerical display of one of those giant build a stack game at Dave and busters. Literally the first thing they had me look at after starting, and that that no one could figure out, I was testing various points with a multi meter when it slipped and bridge two of the legs. At first I was worried a really messed something up, but the dude that had been there forever was like “what’d you do‽ It’s working!”. Definitely a fix I wasn’t expecting.

I’m a web applications developer…. So a lot. But here’s the king of dumb shit fixes I’ve done. Back in the days off VGA a few friends and I met up with some other dudes for a counter strike LAN party. Everyone’s hauling their towers in and if you were lucky, your heavy as fuck 17” CRT. So I set up and my monitor won’t work. Has power, no signal. Switch from the gpu vga port to the integrated one and it works. Switch back to gpu and it works as long as I hold it in a weird position. So it’s all fine, just the connection is massive wearing out. For some reason I figure a little moisture will help so I lick the vga plug, reattach it and it totally solved the problem.

So yeah, I licked a gpu into working again.

I’m not sure if this counts because it wasn’t intentional on my part, but… When I was a kid, my mom had a digital camera. The lense on it would extend when it was powered on, and then retract when it was powered off.

At some point the lense got stuck, which caused the camera to not turn on properly and made it useless so she ended up getting a new one. I had gone to take the old/broken one to mess around with it and accidentally dropped it.

Apparently the angle that it fell at was just enough to “lodge” the lense back into place yet the fall wasn’t high enough to cause it to shatter or break. It worked perfectly after that, and while my parents were a bit upset they needlessly bought a new camera, they ended up letting me keep the old one.

(Later on I figured that was their way of justifying not returning the new camera that probably had nice new features or something)

I also vaguely remembering them saying something along the lines of “That’s probably the only time in your life dropping a piece of equipment will actually fix it and was just luck - don’t go trying that on other things randomly”.

For starters I’m old enough that if your TV or monitor was fuzzy or blurry you gave it a good bang on the top. This worked 50% of the time and was considered common practice but it sounds stupid in retrospect.

But wait there’s more: I boiled a demo disc (videogame magazines used to come with a disc of demos for new or unreleased games). During a particular print run of Official Xbox Magazine many of the shipped discs would skip or fail to read and dropping them into boiling water for about 30 seconds was a way change the refractory index of the plastic and fix something that was causing the laser to be unable to read them.

I guess this is my jam because that last one reminded me of another hilarious practice from that era: “Toweling” an Xbox. First generation hardware of the Xbox 360 we’re prone to detecting an overheat and sometimes entering a state where they wouldn’t boot up anymore and display an iconic “Red ring of death” where the LEDs on the front would light up red and it would it never finished booting. But it was running, just it wouldn’t continue. While it was getting a little warm, it seemed to be more a failure of the sensor rather than a catastrophic overheating. So naturally the solution was… Get it hotter. Wrap it in towels blocking all of the fans from doing their job and get it hot enough that the sensor would seem to go out of range and reset itself. This returned it to normal operation for hours or days, for some people indefinitely. Fortunately I haven’t “toweled” any electronics lately.

I wanted to install an extra hard drive in my computer, but the power supply didn’t have enough connectors. I actually had a spare power supply unit, but upon testing, the 24 pin cable was too short to reach the motherboard.

I ended up using both PSUs. Only one had a power switch on it, so that was connected to the hard drives. I had to use a paperclip in the unused 24 pin connector to make it output power. The 2 PSUs had a wire running between the ground pins of a random unused connector, and they were on the same phase circuit.

The hard drive PSU had to be turned on first at the switch. Once that was on, I could press the power button to turn on the computer. I think I used it for about a year before buying enough upgrade parts to effectively replace the entire computer.

I stabbed a router with a knife twice and it worked. It knew I wasn’t fucking around now.

Friend’s desktop was so fried from Kazaa and Limewire, that he couldn’t even open a Windows explorer window. Ended up opening Notepad and copying all of his files to a thumbdrive using the file open dialog box before reformatting.

Turned it off … and then turned it back on again. It feels stupid, but it fixes way more issues than it should.

Early in my career (a long time ago), I was tasked with ordering replacement chargers for some laptops. I ordered several off Amazon and even though they were labeled as being what we wanted, they were apparently bootleg and were not, in fact, the correct charger. Fried a few laptops before I realized Amazon wasn’t the “Amazon” of yore selling first-party parts and I was ordering from random third party sellers. (That was all relatively new at the time. Amazon was a bookstore branching out in my head.)

In fairness, I was a programmer and not an electrical engineer. And chargers back then weren’t exactly USB-C level smart. The barrel charger fit. I just thought “Oh, what a great deal. I’ll order these and get plaudits from my boss for saving money.” It wasn’t even my money.

The other one is that when I was learning to code — I’m self-taught because everyone was back then — I used Vim and invented my own style. All my code was basically unformatted or, at best formatted consistently in a very non-standard way. That’s easy to fix nowadays where I can hit save and my code gets formatted automatically but it wasn’t so simple back then. I still feel bad for the engineer who followed me who had to fix that shit.

I just spent the better part of the day trying to get a “music archival tool” to work, but I wasn’t able to get my Spotify account to connect.

The eventual solution I ended up with was to spin up a Windows VM, get the tool connected to my Spotify account there and copy over the config file from the Windows installation to my (Linux BTW) actual computer.

Of course, I’ve never really dabbled in emulation past old video game consoles, so getting a Windows VM up and running involved its own troubleshooting… The whole thing felt absurd, especially since there are so many easy ways to download music, but this was one of those times where I didn’t want to let the computer best me.
