Volt meters & ampere meter with PIC can be used to measure voltage and current simultaneously. The series of volt meters & ampere meter with PIC16F876A PIC is used as a data processor voltage and current are measured.  This circuit uses the viewer in the form of 16 × 2 LCD used for the data display voltage and current measurements. In the article volt meter and ampere meter with PIC are discussed kerannya limited to devices only. More detail can be seen from the image sequence volt meter and ampere meter with PIC below.  The images of Volt Meter & Ampere Meter With PIC Circuit Volt meters & ampere meter with PIC  

This is an amplifier circuit based on IC AN374 which has a 1 Watt output power with supply voltage and a maximum of at least 8 volts to 16 volts with the DC current. Following amplifier circuit 1 Watt l 8 - 16 Volts Audio Amplifier. 1 Watt l 8 - 16 Volts Audio Amplifier

This 16 LED Chaser Circuit Diagram is a double direction flash. Similar to Digital Ping- Pong 1, there is a movement of a lit dot, up and down along the LED's length. 16 LED Chaser Circuit Diagram When the D16 lit the situation changes and there is a reverse movement. Lit D15-14 ……D16, is lit making circles when the circuit is under power. The IC1 is an unstable flip- flop supplying with stable frequency pulses (the frequency can be changed by TR1, adjusting the velocity of the LED's up and down). This frequency supplies the IC3 (which is a 4-Bit UP and DOWN counter) through 2 gates A-B of the IC2. The output counter supplies the IC4 that is the driver of the LED's. The parts C- D of The IC2, make a R-S flip- flop, that changes situation, when the edge LED's D1 and D16 lit. We have an electronic limit for the situation change. In proportion the shape we make with the LED's, we can have the proportionate optional result, making various effects. Part List R1= 100Kohm...

In the last blog post, we made a new nut for our vintage Hofner Colorama II. Also needing doing is an improved bridge. The original one should've looked like this: However, here's the (replacement) one I got on THIS guitar: Apart from looking wrong (not necessarily a big problem), it has the wrong radius, wrong string spacing, and is not compensated in any way for proper string intonation. The base is almost correct, dimension- and look-wise, so I'm going to keep it and make a new top. First I get a brass bar: Cut it to length to match the base: Mark the position of the holes and hit them with a punch: Now the tricky part for me, since I don't have a drill press - drilling the holes perfectly straight: Holes done: Now turned over to check how close I got. Not bad. Quick check with the base before taking this any further: Sides are now marked with a 9.5 radius gauge to match the neck: The brass is now filed to shape, checking constantly with the radius gauge to make sure...
