Here’s a circuit which stimulates nerves of the part of your body exactly where electrodes are generally attached. It is useful to help remedy headache along with muscular discomfort and bring back frozen muscles that impair movement. Though it offers muscles stimulation and invigoration, it’s mostly an aid in removing cellulitis. The device comprises 2 units: muscular stimulator and also timer.
Here is the circuit diagram of stereo digital volume control. This circuit could possibly be applied for upgrading your manual volume management within a stereo amplifier circuit. In this particular circuit, push-to-on switch S1 controls the forward (volume enhance) operation of the two channels while a identical switch S2 controls reverse (volume reduce) operation of the two channels.
The above diagram is a hierachical priority encoder circuit. Described on wikipedia, priority encoder is a electronic circuit or algorithm that compresses multiple binary inputs into a smaller number of outputs. The output of a priority encoder is the binary representation of the ordinal number starting from zero of the most significant input bit. They are often used to control interrupt requests by acting on the highest priority request.”
Here the simple traffic light controller which is could be used to educate kids rudiments of traffic light guidelines. The circuit utilizes easily available electronic parts. It generally consists of rectifier diodes (1N4001), a 5V regulator 7805, two timers circuit using IC 555, two relays (5V, single-changeover), three 15W, 230V light bulbs and also several discrete parts. Mains electrical power is stepped down by transformer X1 to provide a secondary [...]
