# Dollar bill yo-yo

Design: Jorge Jaramillo (georigami)

Modified from a square to three dollar bills.

This one was a challenge from Jorge to adopt his model to a dollar bill. The model is made from a square and was too complicated to adopt to a single dollar bill. After several attempts decided to cheat and instead of one dollar, use three. And it worked perfectly. This is a simplified version of the original model. Now that I figured it out, I will be working on the version similar to the original.

Thanks Jorge for the challenge!

1. Congratulations on this achievement, I'm pretty sure the hourglass would be a lot easier to do with a single bill than the yo-yo.

2. Thanks! I think the hourglass will be made with 9 dollar bills! I want to keep the same proportions as the original and working on the yo-yo gave me a good sense of how to complete it. Can't wait to see another great model of yours!

3. I have finished the hourglass adaptation, only trouble is, all banks are holding the new dollar bills for december!

4. He he he, I'll be patiently waiting for the final model.

5. Great news Jorge, got brand new crisp dollars bills today! I'll be working on the new models over the thanksgiving weekend.

6. Alguna vez terminaste la segunda versión de este modelo de la que hablabas en tus comentarios?

7. Jorge Jaramillo Hola Jorge! Si, pero no con billetes, lo buscare y haber si lo subo pronto

8. I could this in my sleep.

The height of the "hourglass" is a simple trig calculation.

The cap is the diagonal passing through the center of the polygon.
