Show off some electronic art.

One day I will make my own, but in the meanwhile, you can share here some electronic art like this:

Have fun  :)

I made one a while back:



The CPU is an AMD Phenom II X4 945 from a previous home pc build.

That actually occurred to me as I went ... I hid a black power resistor on his back, you can see one of the leads hidden behind the right-hand leg diode as you look at your screen.  (Actually I shouldn't have said that, because in the pic you wouldn't think it could work, judging by the orientation of the diodes  ::) )

It was meant to get power through its feet, with current flowing into the resistor shunting around the left leg, and returning through the right), however what I didn't account for was the fact that I apparently got one or both of the power rails when I soldered the feet down, so the legs are actually shorted together! I was just killing time on a Sunday so I didn't bother fixing it - its just a decoration after all - but now the only way to light him up is to power him through his arm as though he's being shocked!

My wife's handiwork.  I think I might have another at home as well.

And you were wondering "where did I put that TO126 Transistor?"  :D.

BTW I like it, and the others too. Good imagination and a little spare time for some fun. :)
The odd multimeter or 2 or 3 or 4...or........can't remember !.

Not mine, but a recent favorite find.  High Voltage EPROM Man.

This is awesome!!
How did he got the HV inside the EPROM? just finding the right pins?

He is applying it to power and a non ground pin, so it will arc over inside pretty well.

It looks like he burnt the bond wires, otherwise they would short the high voltage. Now the high voltage is arcing from the pins to the chip.

Wow, a CDIP dated 1997.

 I don't think that's what they mean by burning an EPROM.....

Thought I would show this, which I made when I was in training. Had another project, along with a power supply, but that sadly was stolen at some point.

I think it basically finds it's own way.  :)  As long as you are on opposite sides of the chip -- same side and it might arc across the edge of one side of the window.

Wow, a CDIP dated 1997.

I was going to post that DigiKey has 27C512 UV EPROMS in windowed ceramic package, but now I see that they are all listed as "non stock."  I wonder if any are still being manufactured.

I don't think that's what they mean by burning an EPROM.....

Now you are giving me ideas.  :)

 Hmm, I have one or two of some sort of windowed EPROM sitting around - no idea where I even got them or what sort of code might be on them, I should see if they are still readable before sacrificing them to high voltage arcs. Given that I've always kept them with an 8085 CPU and some support chips, if I had to guess it has the code to run whatever I pulled it all from - I think it was some sort of home brewed interface to a Teletype.

Didn't think to post this before.  A couple years ago I made this little cube out of some worthless 28 pin PLCC chips.  I soldered 4 together in a square, made 6 squares, and built a cube.  Because I put the bottom of the chips out I couldn't solder the edges of the cube together, so they are actually glued to a cube of wood inside that I painted black first so it would show through any cracks.
