A few years ago, I bought this glue called "welding glue", which was a tube of super glue and a box of black powder. I don't know what it was, but it has a same effect as baking soda. Anyway, good job on the power supply, these DIY projects are gold 🙂.

When I look at the reaction, the powder that are used, have a really large surface. And the thinner the super glue is, the faster it dries and get hard.
Are cinnamon not more fine in grain size than baking powder by the way?

Anyway. I actually managed to produce smoke from the use of cotton. I have no idea if that is too dangerous.
Also, the fumes hurt the mucous membranes in the nose and makes the eyes burn.
So getting too close are not adviceable at all.

The dark or black powder in that kit you wrote about, might be powdered graphite. I might look for some of it and give it a test. Or perhaps toner from laserprinter.

And thanks regarding the PSU. I have no idea if it is safe enough, with my job on the 240v line. If insulation are good enough or something.
I just used my knowledge from electrician ground school about safety, and increased insulation and that stuff. Even modern PSU's with that switch, leaves the leads unshielded inside.
So I hope it is safer than generic factory made, CE labeled stuff.

I guess getting shock by live wire is part of the job 😅. Last year repairing a dryer, and it has a broken solder joint and piece of a plastic (for holding the heater in place), so I grab the heater thinking I was unplugged it and I got zapped 😁. And that was one of many incidents 😅.

The live wire looks the same as the others, it just has a different grip 😀

I mostly finished setting up a DOS sandbox for running a wide variety of games (just a couple of the mixer shortcuts left). Mostly to make it much easier to adjust the system configuration in LaunchBox for each game as needed.

was given an ancient box by wife's family. I was just curious what it was. I didn't want it, and I said so.

Anyway, it's an ancient VLB 3/486 mobo with TI 386 and FPU, and I think 8mb of ram.
Quick wash, and it looks surprisingly ok.
Battery was changed out decades ago to a couple of long wires and a CR2032.

Next... wash the PSU and monitor guts.

Then... does it explode?

How many tantalum’s does it have 😉

LOTS!
iirc those yellowy-orange plastic things are tantrums, right?

May the force be with you….🤣🤣

Repaired my Saitek X35T flight throttle. Some plastic piece inside snapped, which caused the throttle to slip and lose all tension. I glued it back together, scanned the outline and measured it carefully with my calipers, and then 3D printed a replacement. It works great!

That's it, or near enough

Half wondering if there is a way to... Add voltage to them slowly

If there is a bad one then best case scenario is it shorting and the PSU catches it. Worst case is it blowing a chip like with what happened to me Smoke coming from PAS16 [FIXED]
