I've been trying to design a very simple repeating timer without an IC555. Unfortunately, I'm not versed in electronics enough to fully design it myself. The concept is similar to an astable multivibrator and goes like this:
A cap charges off of a battery, and as the capacitor nears fully charged, the circuit switches and allows the cap to discharge through a secondary device (LED, relay, etc) until the capacitor is discharged. The circuit then switches back to charging the cap.
Any help would be appreciated.
