<< Hello HF,
Attached find the D1_Reg_Flasher (pummer) circuit which I build a few months
ago. After a sunny day, it happily flashes one LED about once per second,
dusk to dawn (8Hrs). The solar cell is a Sunceram BP 373334, courtesy
Solarbotics, which charges the 1F memory cap (high internal resistance no
object). The brightness is uniform throughout night. Unused inverter inputs
must be grounded. Up to 6 LEDs can be used but use different resistor values
to avoid phase locking. Fine tuning one or two frequencies with pots can
lead to interesting random or long period patterns.
>>I've got a question about this D1_Reg_Flasher circuit. Actually two.
1.) What are the slashes in the "powersaver 2v flasher" all about? Those
aren't caps are they?
2.) I'm assuming that you can add more than one "powersaver 2v flasher"
circuit to this pummer, so you don't waste a bunch of gates. How would you do
this? Any special way?
Thank you a ton Wilf, it looks like a fun circuit to try!
not a robot scientist
not a college major
not a grad student
not a professor
not a very organized person
just Spencer (isn't that impressive enough?)
I didn't write this!
