16 Watt Power Amplifier Circuit parts: U1 U2 LM383 8 watt audio amplifier ic R1, R3 220 ohm resistor R2, R4 2.2 ohm resistor R5 1 megohm resistor R6 100k audio taper potentiometer C1, C7 10uf electrolytic capacitor C2, C5 470uf electrolytic capacitor C3, C4, C6 0.2uf ceramic capacitor SPKR1 4 to 8 ohm speaker [...]
10 W Bass-boost Audio Amplifier Schematic Description: This architecture is based on the 18 Watt Audio Amplifier, and was developed mainly to amuse the requests of correspondents clumsy to locate the TLE2141C chip. It uses the boundless NE5532 Dual IC but, obviously, its ability achievement will be comprised in the 9.5 – 11.5W range, as [...]
Laser based projects acclimated to be expensive, until the development of solid accompaniment lasers. This activity is advised for the access akin laser experimenter. The ambit allows any two computers with consecutive (RS-232) advice adequacy to acquaint over 200 meters application a laser beam. A low amount transmitter alone ambit is additionally presented actuality for [...]
Low-cost RS-232C multiplexer serves as multiport adapter Multiport RS-232C PC add-on boards are advised for accelerated multichannel communication. Therefore, anniversary consecutive anchorage has its own manual controller. If your appliance doesn’t charge interrupt-driven service, and polling the accessories through RS-232C channels one afterwards addition is sufficient, again you can use a distinct ambassador with switched [...]
Another method that helps program development besides a dot LED as the output device is a serial bit. With a serial transmission to a terminal emulator program, developer may then test program running easier than a dot LED. One of my circuit uses PIC16F84 having one bit for sending ascii character with “printf” function. The [...]
Audio Equalizer 10 Band Schematic This circuit allows you to equlize the audio signals in ten band. It uses low amount op-amps to anatomy a able blaster circuit. The affection of the architecture is a classical band-pass alive filter. The U11 acts as an attenuator to adapt the arresting akin for equlizing. The U13 acts [...]
