Micro Processor Chess Set





Introduction: Micro Processor Chess Set

Rather than play the computer chess, why not make a chess set out of the computer!

This is version 0.1 (beta). If I can get enough Pentium "586" chips, I'd like to make a regulation size chess set.

Any constructive criticism would be appreciated!

Step 1: Chess Board

The board is the underside of a mother board, and 32 black microprocessor chips.  This creates the colors Green vs Black.  Each chip was attached with epoxy.

The principal hardware was left on the bottom side.  Legs for elevation are bolts press-fitted into the chassis mount holes.

All subsequent pieces were painted green or black, if necessary, to indicate side.

Step 2: Pawns

The pawns are made from capacitors found on most CPU power supplies, with a plastic figure base attached with epoxy.

These were the hardest to standardize- 16 of the same parts was hard.  I salvaged through more than 12 power supplies to get the eight and eight matching parts.

Step 3: Rooks

The rooks are power transformers from CPU power supplies, with heat sinks cut to size for crenelations.

Step 4: Knights

I found some high-end power supplies that had nice relays encased in plastic.  These made good bodies for the knights.  The heads were fashioned from inductor coils, cut into a c-shape.

The top corner of the relay was cut off at 45 degrees, providing an attach-point for the inductor using epoxy.  After attaching, the connection was improved by wrapping additional copper wire around the joint.

Step 5: Bishops

The bishops are the armatures from hard disk drives, with green or black wire wrapped around the base.  The wire increased the base's cross section, improving epoxy attachment surface area.

Step 6: Queens

The Queens are (from base to top)-

1. Clock battery from mother boards,
2. RF choke filter ferrite core from data cable,
3. Electric motor core from pen-plotter motors,
      and crown made of-
4. Hard disk platter washer,
5. with 6 green/black (IR) LEDs for jewels.

Step 7: Kings

The kings bodies are made from motor cores of two paper shredders.

The crowns are hard drive washers, topped with the armature from old Zip drives- creating the holy seal.

    Very cool.

    GOnna have to empty out some spare parts bins this weekend and make one!


    It's almost more fun exploring parts to use.  Motor and the inner parts of drives are filled with interesting parts.

    A tip for the explorer: Since the electro-mechanical function is not necessary, I dropped each circuit board into the washbasin and cleaned the parts off with water.  This removed most of the dirt and residue common inside electric parts, definitely making the job nicer work for my hands.


    Board manufacturers wash boards after assembly in water. They expect new components to function after doing so as well. Place I worked for actually used a dishwasher to clean the water soluble flux off the PCBs after we ran them through our wave solder machine.

    Trick is to just let everything dry out and it is fine.

    how do you remove the microprocessor chips?


    I used a razor blade / skill knife. the tool you buy at hardware stores. Easiest way was simply cut through the feet connecting to the circuit board. Then I just trimmed off the stubble with the razor.

    To desolder quad flat pack packages you can just blowtorch the back of the board and they fall right off. It does stink to the high heavens when you do this though! So it isn't an indoors friendly activity. Some use toaster ovens or frying pans for doing this too. I bet even a barbecue grill would work. Then a big empty cardboard box to catch the hot parts is used. This method is called the, "heat it and beat it technique". Because after you get the boards hot enough you quickly slap the boards against the inside of the empty cardboard box to dislodge as many parts as possible into the box.

    It goes without saying you hold the board in big pliers and wear gloves to protect yourself from the high heat. Safety glasses are stylish as well to protect your eyes from molten globs of solder that can go flying. Most stuff ends up in the cardboard box though.

    Pro tip: after you've slapped the board a few times into your cardboard box transfer the parts to another box, or tray or something so the little molten solder balls don't end up on your parts so much.
