- Codewheels are used by software publishers to thwart piracy.
- It's a great system, assuming nobody can read or write. With
- any form of writing, it's possible to transmit the specs for
- the wheel along with the game. Wheels of cardboard are lined up
- according to keywords on the screen, to reveal the password on
- the wheel.
-
- When I wanna play a game, I wanna play NOW. So spending a few
- minutes figuring out the password from the docs is too long. I spent
- 15 minutes making the wheel instead, which will save time in the long
- run and was fun too. Here are some construction tips:
-
- Paper plates make great code wheels. They're stiff enough to last
- awhile, and easy to write on. Plastic is tough to write on, and cut.
- If you make the circles (where the words go) all the same size, it will
- line up right. To do that, draw them with a compass or use one pencil
- to point the center, with the other held still. Spin the paper while
- holding the pencils still. You also have to devide the "pie" into
- sectors. If the docs have 12 columns, you make 12 equal pie slices.
- 360 degrees (circle, remember?) devided by 12 columns is 30 degrees ea.
- Can't guess 30 degrees? Devide a 90 deg into thirds. If you cut each
- wheel (bottom, mid, top) just a little smaller than the last, you have
- a little room for the keyword, at top of column.
- By drawing the sectors first, and labling the columns, you can
- figure out where the windows get cut. After cutting the windows, use
- them to write the codewords in the right places. You can't mount them
- permanently till they're finished. Use a nail or something to fasten
- the bottom plate, which I leave whole, to the second. Fill out the
- code words through the window in the second, so you know they'll line
- up. Then do the same with the third wheel on top. Just copy off the
- docs the Pirate included.
-
- Now you have to fasten the three finished wheels together.
- you can use a tack or a pin. But to really look slick, find a
- pop-rivet tool, and use the biggest pop-rivet you can find.
- Pop-rivets hold the wheel together tightly, while letting them
- rotate. And it looks great. The bigger pop-rivet spreads the stress
- over a larger area and lasts longer. A smaller screw or rivet is OK
- if you use metal or fiber washers.
-
- It cost a dozen paper plates to perfect this technique. But I can
- spin them up quick and cheap now.
