Write secret messages to your friends. Find out how to use this ring on Youtube: https://www.youtube.com/watch?v=8-q2hLL3Fco


Write secret messages to your friends and decode them with this ring. The Caesar Cipher, or Shift Cipher, is one of the oldest and simplest codes. Simply shift the alphabet by some amount and use that alphabet to write your message, or in this case twist the rings so that the letters line up in the right order.

This is actually 2 nested rings that print interlocked but twist independently. It's big enough to fit on a finger tho it may be too big for regular wear.

How to use:


Both ends of the message chain will need a ring. To encode the message first choose a letter to be the key for the message. Then twist the rings so that "A" on the top ring aligns with the secret letter key. Write the key as the first letter of the message, then proceed to encode the message by looking for the letter you want to encode on the top ring, but writing the letter on the bottom ring.

To decode the message, twist the rings to that "A" on the top ring aligns with the first letter of the message (the key). Then find each letter in the message on the bottom ring, writing down the letter above it on the top ring until the message is revealed.

Just a few notes for anyone planning on printing this ring:
1) It must be printed like the picture above shows
2) After it prints you have to cut threw the ring on the top of the ring to enable motion.

I personally think this is a great product!

IT is a good ring for decodeing

Do you think a version with numbers could be made? It could work very well as a counter (up to 99), but there are only 10 digits rather than 26, so the spacing might not work as well I guess.

Could 26 complex shapes be replaced with only 10? Yeah, I think that'd be possible. Buf it you're doing a count I would develop something that could be viewed from above.

Neat! :-)

Sadly, my decoder earring did not print well (darn small letters...)

Perhaps I should print it at shapeways as well.

I have observed that with extrusion based printers letters like this print better in a vertical orientation. If you can rework your earrings to print vertically like I did on this ring you might be able to fix it.

Shapeways would probably work too, but it is a bit pricy. Then again it's cheeper than a $2k makerbot.

I printed it "standing" but .2mm text just seems to fine. I really can't wait for the Printrbot and try to print with thiner nozzle and layers... The UP is awesome, but limited to it's presets.
