Electronic kits provide useful electronic devices, teach electronics theory and are a relaxing, fun activity. Some kits produce complete products while others are designed to be be used as circuit building blocks for robots, alarm systems, P.A. systems or almost any other electronic project that crosses your mind. Its hard to build one of these kits without learning something about either electronic theory or the practical aspects of circuit building. Each kit comes with a circuit diagram and an explanation of how it works. Electronic kits are also a lot of fun -- some of us find that spending an evening huddled over a warm soldering iron is good mental therapy. Don't forget to check our Soldering Robot Kits and BEAM Robotics sections for more soldering projects!

18W BTL Audio Power Amplifier Module from DIY Electronics



This is a class AB audio power amplifier using the Hitachi HA13118 module. It is easy to construct and has a minimum of external components. The module has a high power output from a low voltage supply using the bridge tied load method, and a high gain of 55dB. This will be especially useful in applications where the input signal is a low level, without requiring the use of a separate pre-amplifier, eg. a guitar practice amplifier. Full current, and thermal protection is provided by the IC, making it extremely reliable. Catalog number: 1732. Brand: DIY Electronics. Brand's Part Number: K105.

Bidirectional DC Motor Speed Controller Electronic Kit from DIY Electronics



This kit allows controlling the speed of a DC motor in both the forward and reverse direction. The range of control is from fully OFF to fully ON in both directions. The direction and speed is controlled using a single potentiometer. Turningthe pot in one direction causes the motor to start spinning. Turning the pot in the other direction causes the motor to spin in the opposite direction. The center position on thepot is OFF. This design avoids the need for a direction reversing switch and avoids mechanical and electrical stress by forcing a smooth transition from one direction to the other. Catalog number: 1742.

It produces standard ChA/ChB raw quadrature outputs, as well as decoded clock and direction signals. The clock signal produces 25 us pulses at each transition of ChA or ChB, providing a 4x increase in resolution - 128 clocks per servo rotation. The direction signal indicates the decoded direction of rotation. Wheels and servos sold separately. Catalog number: 1940. Brand: Tinkering Supplies. Brand's Part Number: WW-01.

Logic Probe Electronic Kit from DIY Electronics



A logic probe indicates the digital signal level (one, zero or pulsing) at a test point. While a standard digital or analog voltmeter can be used to show steady state signals, it can't respond quickly enough to show the short pulses that are common in digial circuits. When using a volmeter most digital circuits appear to be idle or locked-up. Logic probes are small and cheap enough that you can generally afford to have several clipped into a troublesome circuit to simultaneously monitor its overall operation. The logic proble you build with this kit is switch selectable for either TTL or CMOS signal levels and can detect very fast pulses. It gives both a visual (3 LEDs) and audio (piezo buzzer) indication of circuit activity. Catalog number: 1240. Brand: DIY Electronics. Brand's Part Number: K024.
