This hands-on kit has experiments for investigating the following topics: Visible Effect of An Electric Current, Open and Closed Circuits, Switches Control the flow of Current, Series and Parallel Circuits, Short Circuits and many more. Grades: 4-8, Ages 9-13. Includes Teacher's Guide and enough material for five students.
This model SC-750R offers an in-depth exploration of the electronic components included with the SC-750 Snap Circuits Extreme. Ideal for use in home schooling, middle schools and high schools, where students will grasp the basic principles of electronics.
This is a handy portable power supply with a variable output voltage of 15VDC. Specifications: Output Voltage: 1.25 - 15VDC. Output Current: 0.5A @ 8V; 0.3A @ 12V; 0.2A @ 15V. Input: 120 VAC (line cord included). Short Protected IC Thermo. Includes rugged Bakelite case.
This is designed to test your nerves by causing a light electric shock when the probe plate is held and the wires connected. The potentiometer allows one to increase or decrease the level of the shock.
This is a combination of both transistor and integrated circuits (ICs) combined radio kit to teach AM/FM radio design and theory with its comprehensive manual. The unique design allows you to place the parts over its corresponding symbol in the schematic drawing on the surface of the printed circuit board during assembly.
The Mini LED Light Chaser Kit flashes 6 high intensity 3mm red LEDs sequentially in order.
Just 4 LEDs and 4 push buttons provide hours of fun. The aim-of-the-game is to repeat a pattern, which is generated at random. The pattern is played both visually and audible or visually only (selectable). It features 4 difficulty levels, which can be selected at start-up.
This is a great little symmetric power supply designed to provide plus and 1.2 to 24VDC regulated at 1A. Low cost universal symmetric power supply. Just add a suitable transformer and a heatsink. Ideal for e.g. op-amp applications, amplifiers.
This is a general purpose, easy to interface temperature sensor for your projects. The small board makes integration into your project or equipment simple, and the sensor device can be board mounted or remotely located from the board.
This changes your voice to a multitude of effects. Features: Make your voice sound like a robot. Add vibrato effect. Use the 'pitch'-buttons and make your voice sound lower or higher. Bbuilt-in microphone and power amplifier with volume control, just add a speaker. Hours of fun! For parties, plays, recordings, games, prank phone calls etc.
This is the assembled version of the Velleman K4001 7W Mono Audio Amplifier Kit. This small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4ohms. The IC is completely thermally and short-circuit protected. A conventional direct current can be connected as supply Exists also in kit version K4001.
This has a highly sensitive built-in microphone which picks up noises and makes the ghost dance with its built-in motor, make eerie sounds with the built-in speaker, and randomly blink. The unique circuit board design includes two ominous blinking eyes that change with various conditions, including sudden changes in ambient noise.
