Parts missing for easier assembly

Reviewer: from Medford, MN US

This kit, though is great, could use some ic sockets for the chips so they can not be wrecked by heat from soldering. Also the kit could come in different color leds like blue and green.

Back and Forth Scanning LEDs Are Possible with this Kit

Reviewer: from Los Angeles

Get a bag of ten 2N2222 NPN transistors. Connect the Base of transistor as the anode lead of the LED onto circuit board, and the Emitter lead where the cathode of the LED is supposed to go on the circuit board. The Collector leads of the transistors and the positive supply now become the two point where you should now connect the LEDs instead - with anode of LED to the positive supply and the cathode of LED to the Colector leads of each transistor. To make the high tech back and forth scanning of LEDs rather than the monotonous one way running lights, you will need only 6 LEDs. Just short the transistor collector leads of 7th output with the 5th, the 8th output with the 4th, the 9th output with the 3rd, and the 10th output with the 2nd. The ten transistors will activate the Collector current sequentially all the time, but in this instance the 6 LEDs will be lit 10 times in a back and forth manner in this sequence - 1, 2, 3, 4, 5, 6, 5, 4, 3, 2 and cycle repeats back at 1 giving a back and forth scanning visual. If you need to control light bulbs, instead of LEDs, get the reed relays instead. And BTW, if you are using a 5V supply instead of 9V batteries (which I tap the 5V from my PC supply), short the 330ohm resistor to activate the reed relay switches.

OK kit

Reviewer: from DRESHER, PA US

The flashing lights look pretty cool when finished. It was easy to put together, except for the IC's. They fried when I tried soldering them. While you're paying the shipping,you might as well buy two cheap IC sockets.

Great Circuit!

Reviewer: from Conestoga, PA USA

I don't know what the IC problems were with the other reviews, but I had this circuit together, soldered, and fully functional in less than 5 minutes! Great circuit & easy to follow instructions. This can be assembled with very little electronics knowledge!

not bad

Reviewer: from Minnesota, USA

The 555 timer didnt have the notch in it, so i had to experiemnt to find the correct way to install it. The LEDs flash from the first to last, then start from the first one again. Wish it was a BAFF (back and forth flasher like from knight rider)...
