Two L.E.D.'s flash in unison when a 9 volt battery is attached. This kit includes a p.c. board, all the parts and instructions to make a simple flasher circuit. A quick and easy project for anyone with basic soldering skills.
Note: Kits cannot be returned or exchanged once assembly has begun.

Educational Kit
Buy 10 to 20 of these every semester for use in the "soldering" section of my basic electronics class. Very simple to construct but conveys the basics of p.c. board soldering and part placement. Kit has always worked and is now considered to be manditory for successful completion of class. In the semester ending in December, the Red and Green LED's give a nice Christmas touch.

Unusual design!!
This kit is easy to assemble. It uses a 555 but the circuit is not the usual astable design (with a resistor between pins 8 and 7 and a resistor between pins 7 and 6 & 2). Your design has a resistor between pins 8 and 6 & 2 and a resistor between pins 6 & 2 and 7.
Why is the design different?
Can I use the regular formulas to calculate frequency and duty cycle?
Thank you for nice product!!!

harder than sounds
it is a little harder to assemble than they make it sound. EDITORS NOTE:
This is a very basic kit with about eight parts to solder to the board. As with any other kit, part placement, polarity etc must be observed.

Holiday Lighting Animation
This is an excellent, and cheap, way to animate holiday wireframes. Example would be a waving Santa. Just hook a 9V transformer to it, attach it to a couple of ssr's, and you can have a 2 channel chasing circuit. If you buy one already made they can run as high as $50.

Easy and Fun
This was a fun and easy soldering project for the kids in the Kalamazoo ARC Youth Group. A fairly easy project, and a little more than basic soldering skills are required.
