Nice toys, Archangel.

I was also inspired by the JDM post. Problem is, I tried to get smart and substituted the zener for a 7805 (have a bunch of those).
Maybe it's better to try the wheel round first before testing if square works!
On that JDM post again. How in the world does he get such a nice PCB using the iron-on process. I was doing that years ago and even started using magazine paper way back as my own idea(now suggested all over).
The color fliers dished out at traffic intersections also work well.
