Need A Little Lap Time?

This little electronic marvel is for timing your speed and counting laps on "S" scale (1:64) race cars. Think Hot Wheels®. Think Pinewood Derby. Made for Radio Shack as ZipZaps Micro RC", it uses infrared LEDs and sensors to measure speed in ft/min or mph, and records individual lap times for up to 6 laps, calculates total time, and stores the fastest lap time and speed. The main unit shows speed and time on 1-1/8" x 5/8" LCD displays, and has a red indicator light to show that the sensors are aligned. (Sensors will work best in a room that isn't over-lit). Measures (1) car at a time, and takes a total of (2) "AA"s, and (2) "AAA"s.

Plasmagorical!

The perfect nightlight for the laboratory or for the mad scientist at home, each heart-shaped plasma bulb screws into a mini-socket (1/2" dia) in the included, switched, wall-outlet adapter, or can be unscrewed and moved to any candelabra socket. It strobes happily along by itself, but will follow your finger, or the cat's paw, like good plasma lights everywhere.
