The most interesting aspect of the circuit is how an ordinary 555 is used to regulate the output voltage. Now, there are hundreds of switched mode controllers ICs on the market which are all better suited for this job than the 555. The problem with all these ICs is that if you build a nice [...]
This circuit effectively functions as a logic-level indicator or logic probe for TTL circuits. It gives an indication of any of the following four conditions that might be found on a typical digital circuit and thus provides a versatile troubleshooting aid:……………..

The Cmos 4060 is a 14 bit binary counter with a built in oscillator. The oscillator consists of the two inverters connected to Pins 9, 10 & 11; and its frequency is set by R3, R4 & C3.The green Led flashes while the oscillator is running: and the IC counts the number of oscillations. Although [...]
