I love how "shotgun debugging" works.
Let's say the microwave doesn't work. I put my burrito in it, press buttons. Nothing happens.
Any sane person would trace the possible cause: Check if it is plugged in, maybe the fuse is blown? Nah, we don't have time for this: Let's try shotgunning it!
- Turn the burrito upside down.
- Try aligning the burrito in different cardinal directions.
- Press random buttons
- Remove burrito wrapper
- Separate burrito into single components, sort them onto a plate in a nifty layout and try microwaving that.
- Remove each component of the sorted burrito plate and try microwaving the plate with less and less items.
- Try microwaving each separate item and then later reassembling them back into burrito to see if it gets heated after the act.
- Try putting a cat on top of the microwave.
- Pour water on cat
- Notice a strong reaction involving water and the cat.
- Try catching the cat for additional testing.
- Go to the hospital to get stitches on your open wounds.
Later write a bug report to the maintainer: "Microwave doesn't work. Tracked the issue down to the moisture level of the cat, additional testing needed."7 -
Alright. Two dead Commodores.
Over 15 years before I was born? ✅
No idea how BASIC works? ✅
Internet at the ready? ✅
So far I've checked various chips for visible damage, and nothing except a blown fuse on both machines. Apparently it takes dual 9vAC and single 5vDC. The 9 powers the SID and the video output, the VIC-II heatsink is off, and I've tested the PSU voltages and one of the 9v's is dead. I'll be getting new fuses and a new PSU soon. Any recommendations on other things to check or things to do when they're done? Pic included because why not.

Concerning my last post on the two Commodores, (https://devrant.com/rants/963917/...) here's the great story behind the boxed one.
So at the place where I interned over the summer, I helped the tech dept. (IT herein) move to a new bldg. We had to dismantle most of the network infrastructure stuff, so we were in the server room a lot. First day on the job, Boss shows me server room, I'm amazed and all because this is my first real server room lol.
We walk around, and there's a Commodore 64 box on a table, just kinda there. I ask, "Uh, is that actually a C64?" B: "Yeah, that's E's." Me: "E?" (name obfuscated) B: "Yeah, E's a little crazy." Me: "Is it actually in there?" B: "Absolutely, check it out!" *opens box and sees my jaw drop* Me: "Well, alrighty then!" So that lingers in my mind for a while until I meet E. He is a fuckin hilarious guy, personifying the C64, making obscure and professionally inappropriate references. Everyone loves him, until he pranks them. He always did.
We’re in the server room, wiping some Cisco switches or something, and we have some downtime, so I ask him about the 64, and he's like "Yeah, I haven't had time to diagnose her issues much. If you want her, go ahead, see if you can make it work!" Me: "You're kidding, right?" E: "Nah, not at all!"
That day I walked out with a server motherboard, 2 Xeon CPUs and some RAM for the server (all from an e-waste bin, approved for me to take home from boss) and a boxed C64. Did a multimeter test on the PSU pins, one of the 9vAC pins is effectively dead (1.25v fluctuating? No thanks.) but everything else is fine except for a loose heatsink and a blown fuse in each C64. Buying the parts tonight. I wanna see this thing work!1 -
Seeking help from anyone able to read Laptop motherboard semantics sheet
In short: Looking for a blown fuse on Laptop (Dell Inspiron 7547) near LCD cable connector, as not getting backlight after a new screen installation. Screen is functional and is detected properly and the device is passing all the diagnostics tests.

Was doing some chill programing when all of a sudden we lose power in the entire fucking house! So not just a blown fuse or something, but looks like the entire street has it, so no telling when it'll be back on either -_- Also I reaaaallly need to buy a UPS for my server, this is happening way too fucking often.5

Bought a cheap coffee maker a few weeks ago (only 22 bucks). Worked just fine.
Now it stopped working and I debugged it, the thermal fuse is blown and the warranty is gone too..
A small price to pay for knowing what the problem is though 😅2
