Took me a couple of days to recombobulate after doing my thing at Makers Faire; well worth the time tho; got to 'proof' my new (used) RV B4 taking it to BM, etc. Main reason I went was to force me to get a Play-bound toy to a point where I could at least proove the concept; this was my Stamp-controlled flame calliope. Didn't get it entirely done but got it to a point where I could play an abbreviated scale with compressed air. Hope to spend the next few months perfecting the contraption.
If anyone's been dreaming of something similar I've been thru quite a learning curve and I daresay I could save the next guy some headaches! :-)
