Hello Everyone...
I am trying to make a Low Voltage Buzzer Warning that beeps on and off, without a microcontroller....
I have a latching detection circuit here that puts out about a 6V signal until the battery is dead, then it drops off and latches off until it is reset....
This is the...
I have this circuit built, and the first batch of 6 pieces all worked.
Now the second time, I made 4, and only 1 works, the others all do the following.
When the voltage goes below 16.2V, the output drops to 7.8V and something buzzes softly. The voltage then after a bit, does go down to zero...
heres my project and or idea.... im trying to use a two way radio to signal another two way radio. i have 12 VDC magnetic solenoid thats hooked to a bird launcher(big sling shot used for training retrievers). when solenoid receives power it retracts in turn releasing the latch.... i have done...
