- Maybe my questions may sound noobish, but...
1. There seem to be many variations of the common Herbie circuit
around the Internet. Of course Randy's original version:
http://downloads.solarbotics.net/misc/herbie.txt then there's the
http://downloads.solarbotics.net/misc/herbie1.gif and some other
variations. Usually there are slight differences in the arrangement of
the photodetectors. So, my question is, which one of the many Herbie
schematics do you prefer? Or, which one have you built, how does it
2. Can LDRs used instead of photodiodes without any modifications?
3. Which voltages have you driven it at? I've got some nice small 3.6V
rechargeables and I would like to use them. Perhaps two in series?
Thanks for your patience!
