Above that there is a memory cell for X,Y coordinates. Send a dot signal to this to reset it. Necessary if you want to reduce R (reducing by 1, step by step after it has generated at least 1 point on the current R might work though). If R is increased you don't have to reset this memory cell.
The big power pole on the right is connected to the output red wire. The output also contains a construction bot signal because I've debugged this with Recursive Blueprints.
No mods are necessary for this. The Nixie tubes (Santas simplified ones) and the pushbuttons are just for debugging and control and it works without them. Pushbuttons are neat if you want to test this though. Makes it easy to configure R and reset X,Y memory.
The top constant combinator (next to a lamp) that outputs a check=1 signal is used to run/pause the generator. No state changes and no output is given unless a check=1 signal is sent in. This can be useful if you are using this with big blueprints and Recursive blueprints mod if you need to slow things down.
That's all for how to use it.
TL;DR
Input R gives coordinates out (while check=1) every 16 ticks.
Reset X,Y memory cell (with dot in) if R is reduced.
It works by measuring squared distance of some points nearby current X,Y values and moving to the next point from one of the valid on-circle points "in front of" the current location state. I'll write a more detailed description of how it actually works, what each group of combinators do and how it was designed if someone asks for it.
Edit: blueprint updated with automatic radius increaser, or "spiral" generator. When it reaches top part of the circle radius is incremented by one so it can make larger and larger circles.
