My old man used to have one of those. Maybe it could be hidden somewhere on his massive stuff stock. Those are common in Cuba too
How does he not suffer some sort of severe burns .
It looks weird. When I made my first home made soldering gun, secondary was in the center over the primary. That was 50 years ago.My Excalibur
I think this is very weird.......my two Excaliburs........and my source of flux.
It's a genuine DeWalt adapter but yes, they work great.Hehe John. Those Ebay battery adaptors work like a charm. I have them on all my older tools.

I thought you were running the nailer on themBtw, I hope the D cell batteries in the background doesn't confuse anyone.
You may use CVBS board LCD Screen instead of photoframe.I would like to know if anyone has taken out an LCD screen from one of those incredibly cheap digital picture frames? If so, what kind of interface does it require?

I inherited from my grandfather an amazing power transformer with multiple low-voltage taps. I have no idea what its original purpose was, but at the time I was interested in what effect electricity would have on ordinary tap water. IIRC, I was maybe seven or eight years old at the time and living with my grandparents in Tennessee while my mother recovered from tuberculosis at an army hospital in Aurora, Colorado. This was about the same time that the "miracle drug" streptomycin was first used to treat TB patients, but in the year or so it took to kill the tuberculosis bacteria in her lungs, I got to play with electricity as taught by Grandfather, a retired coal mine electrician.To show my electrician apprentices the danger of fire from, say, car batteries, I would sharpen a half length H pencil at both ends and connect it with crock clips across a 12V car battery or similar, capable of supplying a couple of amps. The pencil would be about 6 to 12 Ω and about 1 or 2 amp would flow resulting in a power dissipation of 12 to 24 watts. The graphite in the pencil would heat up and after 30 seconds or so the paint on the pencil would start bubbling and lovely delicate smoke spirals start to emit from the pencil ends. Then the pencil would issue small flames from the ends, with the wooden body of the pencil finally and dramatically bursting fully into flames and falling off the graphite in two halves, leaving the graphite itself glowing red hot.
My apprentices were happy to accept the dangers from electrocution but not all of them seemed to understand the dangers from low voltage high current until this brought it home to them.
Two things worried me about the demo though. The first being that they would go and show it their friends and burn down their car, house or garage! The other was that the burning paint can be quite toxic and can certainly set an asthmatic off. I would stage the demo outside or in a fume cupboard if I could get hold of one.
Well, a lot of the components we are discussing have the potential to create corpses. Is that any good?I came here to find some components to reanimate corpses, and all you guys got are vintage computers. Where is the arcane tech? This thread is making me want to hit some junk yards.
Not "basically free", but I did buy something like this for an old PC PS.I was actually thinking about taking an old power supply or two (probably pulling from computers found at the local dump) and modifying them for use as power supplies, I mean it would be basically free, just need a little modification
