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.

Interesting, hand-drawn schematic for a PLL FM Stereo Transmitter, with approximately 5 Watts RF output power.
Complete instructions and circuit diagram for a Geiger counter meter device, which will allow you to measure radiation levels.
Schematic, circuit design and comprehensive details about a SUPRX FM radio receiver, featuring high sensitivity and very low noise and distortion. [PDF]
Variable-voltage DC power supply circuit. The output DC voltage is adjustable from 0.7-24V, with current limiting range from 50mA up to 2 Amps. Main transistor is the 2N3055.
Schematics for electronic circuits that detect lightning in the sky by sensing signals at approximately 300kHz. Circuit theory of operation is discussed at length. Easy to build!
The Veronica 1 Watt PLL FM Transmitter is a pretty decent broadcast PLL exciter or transmitter that can be used alone or with an RF power amplifier for high power radio broadcast.
Flash you car's headlights on/off, either together or alternatively, with this flashing lights electronic circuits. Don't know if it's legal but it's pretty cool :)
An electronic circuit that uses a 556 (Dual timer) IC to produce a two-tone train horn sound effect. Equivalent circuit using two 555 timers (single timers) is given.
Circuits that operate just like the real gameshows, where a light shows up for the first contestant to hit their answer button.
This super cool circuit behaves as a clapper-switch. You clap and the circuit turns on. Clap and it turns off. Great as a light clap switch.

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.
