    PWM using 555 timer

    Darrin, I tested the circuit in Isis and it seems to work fine. The pulse width is variable from 0 to 100% by varying the voltage at pin 5 from ground to supply voltage. Ante

    PWM using 555 timer

    Darrin, It is very rare to use pin 5 on the 555, I can remember once I have used it and this was for the purpose of detecting missing pulses. However I found one example but it does not provide and formulas. Ante ::)

    Problem with LEAD-ACID Battery

    Rhonn, This is much too early to get this stuff on your battery terminals. It is caused by acid leaking round the terminals where these go through the top lid. The acid forms crystals, this is like highly concentrated acid. Don

    Mini golf cart from UPS batteries

    Darrin, The batteries are usually connected in series and not loaded individually (no tap on 12V) and should be equally in voltage. I think they are beyond salvation, but you can give it a try if you like. These UPS batteries have a tendency to dry out if not properly maintained. They are called
