Velleman MK173 Mini LED Chaser

You may have seen this type of lighting effect in classic TV shows (on cars, in robots and others). Now, you can have your own with the Velleman MK173 Mini LED Chaser. You can mount it in toy robots, RC cars mount one in your computer, or put one your Halloween costume. The scan rate is fixed at 0.5 seconds from side to side, but you also have the option scan in one direction just by adding a jumper. The six high intensity 3mm LEDs will draw about 20mA at 12 Volts DC.
