    Thanks Gareth, much apreciated.

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

    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?

        Jim. Thanks so much for the schematic. Would you mind if I post it on Facebook and http://www.instructables.com? I will be sure to prominently ID you as the designer… I think it would be wicked cool to see this go “viral.” I’m going to mount a solar powered one in a jar on a base with appropriate label (etched brass maybe). “Hans R. Camenzind (1934-2012), designer of the 555 chip, (555 memorial design by Jim Frize)”

          Sure no problem, glad you like the circuit. Send me a link of your post/s too so I can check it out (jim@sonodrome.co.uk)

            Thanks… and Will Do… and thank you for thinking up such a nifty memorial…

          We’d love it if you posted this to Make: Projects (makeprojects.com). I was thinking about driving a “campaign” to have a bunch of these memorial circuits made. If you put it up in M:P, we can promote it through all of our channels. Should get a lot of interest/attention.
