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.
enjoy
