Show off some electronic art.

[ZeTeX]

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

Have fun 

[Mark]

That is awesome, I'm going to make one of those!

I made one a while back:



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

(Edit: Sorry for the image size)

Do it right and his head could light up   

[klr5205]

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.

Have a look at Mike'e Electricstuff

Another classic. Not mine:

9V are evil...
This is well known.

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

BTW I like it, and the others too. Good imagination and a little spare time for some fun.

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?

[SeanB]

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

[bktemp]

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.

[Stonent]

Wow, a CDIP dated 1997.

[rrinker]

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

[SeanB]

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.

Now you are giving me ideas. 

[rrinker]

 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.
