duffman said:fascinating!! so a 555 timer circuit at 6 volts, uses the same components at 3 volt?! thats awesome. But doesnt the rate of flashing and all that rely partially on voltage?
The problem is overcoming the LED forward voltage drop while using a 1.5v (or less) supply.bogdanfirst said:LM3909 is not intereting...
for a 1.5V flasher use a COMOS 555 like ZSCT1555(works down to 0.9V).
also try LMC555, TLC555 ICM7555
I found **broken link removed** in a quick search.... four transistors and a few resistors.alanzhao said:Does anyone have LED flasher circuit diagram using 1.5-3v battery and 555 timer?
