…dress up the project, a favorite photograph can be placed in the heart, and a frame can be made to fit the circuit board. Complete explanation, please visit this page…

…first project” for your students… 🙂 and the result should be like this: Replace the Resistor 10K with variable resistor 20K or replace the electrolytic capacitor 100uF with other value…

…input level is also suitable for use with the TDA7000 receiver. All components are easily to buy on the market. Naturally, the project will be built on a PCB which…

…colours); and black and white. It’s will be very useful for robotics project. The circuit is based on the fundamentals of optics and digital electronics. The object whose colour is…

This 300W OCL power amplifier -i’m sorry for the blur diagram, but it should be readable- use 4 pairs of 2N3055 dan MJ3055 transistor as the main power components. This…

The following diagram is the Theremin music instrument effect. A guitar or instrument amplifier is an ideal companion unit for the theremin; either one allows bass or treble boost, as…

…pretty impressive and perhaps a bit complex, it’s actually not difficult to understand. The circuit needs to be hooked-up to a DC supply voltage of between 16.5 and max 17.5…

…burglars / intruders. The following is an example of a touch of alarm circuit which is designed by Tony Van Roon. Components List: R1 = 100K R2 = 56K R3…

…and comes with fairly good quality output. Each IC contains dual op-amps circuit, so you will need 4 ICs of NE5532 or LM833 to build this 5 band graphic equaliser….

…and toys but, applying a high output energy audio amplifier IC, it could be implemented as well in further complicated projects. Circuit operation To receive a realistic automobile horn sound,…
