Time Interval Relay Circuit for the clock circuit above This is a programmable clock timer circuit that uses individual LEDs to indicate hours and minutes. 12 LEDs can be arranged in a circle to represent the 12 hours of a clock face and an additional 12 LEDs can be arranged in an outer circle to [...]
13.8V 20A Transformerless Power Supply Circuit This PSU has been abnormally advised for current-hungry ham radio transceivers. It delivers cautiously about 20Amps at 13.8V. For lower currents, a abstracted accepted attached output, able of 15ma up to a absolute of 20A has been added. Let us see what we accept got here. The ability agent [...]
Mini FM Received Circuit TDA7021T chip radio receiver ambit is for carriageable radios, stereo as able-bodied as mono, area a minimum of ambit is important in agreement of baby ambit and low cost. It is absolutely accordant for applications application the low-voltage micro affability arrangement (MTS). The IC has a abundance bound bend (FLL) arrangement [...]
