Build your own a cheap simple Microcontroller learning board S-52. The board is based on ATMEL’s new ISP chip AT89S51, AT89S52, or AT89S53. This board can be used by beginners for learning Assembly and C language programming. Single sided PCB file included. Introduction I have designed this leaning board to be used as a tool [...]
50 Watt apmplifier with TDA1514A Here is circuit audio amplifiers for car, which use it only number Transistor Circuit of IC, simple Circuit (and Top Popula) Use TDA1514A transistor at low cost. It best Idea Circuit. It’s receive a handful of additional external device in comparison to the generic diagram. Remember that there’s a simple HF filter on input signal. [...]
Lightning Detector Circuit and schematic This Do-it-yourself lightning detector circuit can be a especially sensitive static electricity detector which can supply an early warning of approaching storms from inter-cloud discharge properly prior to an earth-to-sky return strike takes location. An aerial (antenna) formed of the brief duration of wire detects storms inside a two mile [...]
120watt power amplifier circuit This should be the main power amplifier OCL circuit 120Watt using devices pillar is the integrated circuit LM12 and diode BY229. This interesting routes many good bass and treble alive. convenient to pretend main amplifier. If a friend is the CD therefore has a beautiful voice and Pre Tone Control is [...]
