  1. Thanks Gareth, much apreciated.

  2. Bonus! What a great way to visualize how the standard astable mode works!

  3. It would be a truly epic memorial for thousands (dare I say millions) of these to be made by diy’s worldwide… I don’t suppose Gareth Branwyn would consider posting the circuit? (Yeah, I can figure it out, but I would still appreciate a circuit diagram….) Or creating an Instructable on http://www.instructables.com?

  4. Schematic please.
