|Model Reconstructed by ~Zareste|
I went to the grocery store and found some models that I could hire for pennies an hour. I used Sculpey for the potato and GLaDOS, but I didn't want to bake it for four million years, and I needed a hollow inside for all the electronics so I made a potato-ish shape with aluminum foil. Keeping the outer layer of aluminum foil as smooth as possible will help when the foil is pulled out of the baked Sculpey.
As you might expect potatoes are particularly easy to sculpt. Imperfections are the main feature...trying to keep fingerprints and fingernail marks out of the clay is the most difficult part of it. I don't have a picture, but the large hole (through which electronics are inserted) was cut out of the clay before it was baked. Scupley isn't too brittle after baking, but I didn't want to take a chance cutting a huge hole in it... I also put the nails in before baking so that the puncture spots would look more realistic.
° F for 15 minutes per 1/4 inch. These parts took a little over 30 minutes. The clay wont be hard right when it's pulled out of the oven, but once it's cooled it will be pretty hard.
After baking the parts were sanded smooth and washed with a damp cloth before painting. Sharp edges can be removed by sanding or with a knife.The aluminum foil pulled out from the inside of the potato pretty easily, again the smooth outer layer of foil really helped.
For the smaller parts (the over-sized chip and the colored bangles on the alligator clip cables) Sculpey was used as well. Rather than fire up the oven again I just pointed a heat gun at them for 3-4 minutes (the temperature was 275° F-ish again).
I painted everything with acrylic paint. Sorry no in progress shots of that, I wouldn't be the right person to explain painting :). The Sculpey is very drill-able so after painting I drilled all the holes for the black wires and red LEDs.
Next (well actually first) came bread-boarding of the audio/LED circuit. Good luck figuring that out from the picture :). Circuit diagram below.

The red LEDs were put into their respective holes and the small wire used to connect them to the battery was super-glued to GLaDOS/the chip.
The speaker was sandwiched in between the control and LED boards and copious amounts of hot glue was applied.
The hotglue around the LEDs got some black paint layers to block out unwanted light.
The small wires to the red LEDs were also painted to match...sorta.
Apply power, cross fingers....
The alligator clip wires were super-glued into holes on GLaDOS. The yellow one in the model (first picture) has some extra bits near to GLaDOS. Those extra bits I made with heat-shrink wire wrap and another peice of Sculpey painted black. The six black wires around the circumference are all that is used to hold GLaDOS onto the potato. I think they're supposed to be staples, but whatever.
Completed GLaDOS portion.
The yellow wires that wrap around the potato were hot glued (on the inside) into place. The audio comes from an old mp3 player stuffed inside the potato.

The audio was pulled from here and spliced together in Audacity.
