Resistance substitution wheel (customizable)

This is a clone of the Tandy/Radio Shack resistance substitution wheel that they sold back in the '80s.

The device that inspired this design can be seen in [Big Clive's recent YouTube video](https://www.youtube.com/watch?v=ol-B5CQW3zo).

**This is a pre-release version. The code will see little change but instructions, etc. will be added. Watch this page to be notified when they are released.**

The device as modeled is 4" ∅ × 1" thick (101.6 mm ∅ × 25.4 mm thick). Per Clive the original device is 66 mm ∅ × 17.5 mm thick. In the final version of the code one will be able to generate a smaller (or larger) device but for now bugs prevent changing the size (in specific the thickness).

### Materials needed:
* A resistor for each value (either through-hole or SMD can be used; 1% 250 mW or higher recommended)
* 20 mm or ¾" nut & bolt (metric or SAE) – I used a #8 × ¾" SAE pan-head bolt as I had one on hand.
* Self-adhesive copper tape (50 mm or wider recommended)
* Wire leads with all
