An integrated circuit called the IC L8038 is used to produce somewhat twisted waveforms such as sine, square, and sawtooth waves. It functions by adjusting the frequency, which is adjustable between 0.001Hz and 300 KHz using an external timing capacitor and resistor. It is able to modulate and sweep frequencies using an external voltage input. […]

How To Test a Multi-Core Wire using Cable Tester Circuit
A cable tester circuit is a tool used to confirm that a cable is functioning, usually by looking for shorts (wires that are connected incorrectly) and continuity (open wires). A cable tester circuit is particularly helpful when working with multi-core wires, which are cables that have numerous insulated conductors bundled together. This guarantees that every […]
Simple Tachometer Circuit
A basic tachometer circuit is a DIY electrical instrument for determining a shafts or disks rotating speed. We need a tachometer to determine the rotation speed or revolutions per second RPS of a rotating shaft or wheel. This basic tachometer circuit was created using two seven segment display units and a slotted opto isolation module […]
Simple Cable Tracer Circuit
A cable tracer circuit is a two part electronic device used to locate and identify specific cables within a bundle or behind walls. It consists of two main units: a transmitter and a receiver. Cable tracers are commonly used in various applications i.e telecom and networking, electrical troubleshooting, security and alarms and audio/video Installation etc. […]
Simple Hand Grip Strength Tester Circuit
Do you you want to test your grip strength, like a mini hand wrestling match with yourself? This hand grip tester circuit acts like a fancy meter. It uses a mix of common electronic parts to measure how hard you squeeze a handle. The harder you squeeze, the more lights turn on showing off your […]
Simple Transistor Tester Circuit
Transistors are tiny electronic switches, but how do you know if yours are working or which kind they are? This tester circuit is like a fortune teller for transistors. It is a simple DIY project that uses just a few common parts to check if your transistor is alive and tell you if it is […]
