Electronic Kits & Circuits for Hobby Electronics Builders!

What is Electro Kits Electronics?

ElectroKits (short for "Electronic Kits") is a comprehensive database of electronic circuits and kits. In the blue navigation bar to the right, the electronic "Circuits & Schematics" section features circuit designs and plans for constructing your own electronic circuit projects. The "Hobby Electronic Kits" section features kits that come complete with circuit designs (schematics), PCB circuit boards and electronic components so that you can solder together your own electronic circuits, with minimal effort. Both the Kits and Circuits are of the highest quality.

Control RC motor speeds with this 10 amp adjustable motor controller circuit. Uses a total of 5 2N3055 high power transistors.
A small motor control electronic circuit schematic. Control the speed of your motors with this low rate speed control electronic circuit.
This smoke detector acts as a fire alarm by setting off an alarm when smoke is detected. It uses a very simple bulb and LDR approach.

Electronic kits are packages that come complete with the required PCB (Printed Circuit Board) and electronic components (resistors, transistors, capacitors, etc..) in order to construct an electronic circuit that performs a specific action. A typical example of an electronic kit are Audio Amplifier Kits – which will provide an audio output signal greater than that of the input. The kit constructor usually needs to solder, cut and connect these electronic components, so there is usually a need for a soldering and associated tools.

About our Electronic Circuits

Currently, there are are about 240 products in our database, ranging from simple electronics kits consisting of just a few passive electronic components up to complex microprocessor controlled kits. We also list some of the more popular FM broadcasting radio transmitters don't ask why, we just have an interest in these! We also have electronic reference guides, such as Morse / Moris Code.
