For this: fifty bucks.
- I would write the code for a 24-pixel ring (which is what I have). Changing it to 32 would be a matter of altering one const variable.
- the code would be hosted on github with an "unlicense" license - effectively making it public domain
- pay me via paypal after you have the code and are satisfied with it.
- I prefer not to provide ongoing support for sketches I do on this forum. If you get this, it works, you pay for it, that's the end of the matter for me.
Actually - here it is. If you decide that this is what you wanted and use it, kindly drop fifty bucks into my paypal pmurray@bigpond.com . Heck - make it 20.
