Unique design allows you to place parts over its corresponding symbol on the PC board. Teaches the basic theory of AM radio operation. Detailed instructions and illustrations make it an easy and educationally sound project. This kit requires soldering.
The Crawling Microbug Kit is always hungry for light, it drives towards it. Features include: Two open chassis sub-miniature motors. Adjustable light-sensitivity suits almost any light condition and allows to control it's 'bug-like' behavior. Adjustable speed. Choose between two different walks. And more.
This is a high quality power supply with a continuously variable regulated output voltage adjustable from 0 and 30V DC. Its design is based on three Op‐Amps and incorporates anelectronic output current limiter that effectively limits the output current to from 0 to a maximum of 1.5A.
This has three fully regulated DC supply outputs and two AC center tap outputs. Same as XP-720 in Kit Form. Two DC outputs are continuously variable and one is fixed. Both AC outputs are fixed. Specs: Output DC: 1) 1.5VDC - 15VDC @ 1Amp, 2) -1.5VDC to -15VDC, 3) 5VDC @ 3 Amps. Output AC: 1) 6.3VAC @ 1Amp, 2) 12.6VAC @ 1Amp. Input: 110VAC (line cord included). Includes full enclosure and knobs. Features short circuit protection on all supplies. Variable DC outputs can be stacked to get 3-30VDC @ 1Amp.
This kit has signal output: sine wave, triangle, square wave and integrator (selectable through jumper). Also: signal frequency: about 1kHz (fixed) and output level: adjustable from 0 to 100mVrms (LEVEL potentiometer).
This power supply kit provides regulated 0 to 9 volts up to 100mA. This compact power supply is great for low current applications. Components: 2 resistors, potentiometer, 4 capacitors, 4 diodes, 3 transistors, transformer, slide switch, line cord. Principles taught: rectifiers, voltage regulation.
Bright red, green, and yellow LEDs are positioned just like a 4-way signal. Miniature traffic light as used on four-way junctions. Realistic operation with adjustable delay. 12 LEDs. Great for model railroads, exhibitions, as a toy, ...
This kit alternately flashes two super bright red LEDs with a built-in adjustable light sensor that automatically turns it on at night and off at dawn.
The kit allows you to create your own message for personal advertisements. 12 self definable characters, which are made by the customer. 150 bright LEDs supplied with the kit. Many spectacular light effects on the message, (scrolling, blinking, rolling, panning...). Adjustable effect speed. Vertical or horizontal position possible. Fixed displaying is possible (no effects). Different displays can be synchronized, to create longer messages, or to create giant advertisements.
The kit has adjustable flashing speed with two potentiometers.
8 LEDs. Different LED running effect are selectable (PROG push button).
With the White LED Flashlight Kit you can build a super-cool high-powered LED flashlight that is small enough to fit on your keychain.
This is a more basic self standing kit with a green PC board and 16 bright red LEDs mounted in the traditional tree pattern.
This kit has 16 flashing red LEDs with extra green and yellow LEDs provided to customize your tree. This Christmas tree has 4 branch sections giving it a 3D depth look. It holds a standard 9V battery at its base and will stand with or without the battery.
This kit produces flashing colored LEDs and three popular Christmas melodies! Makes an excellent ornament. Educational kit complete with PC Board and detailed instruction book.
