A former President of the Magic Circle, three times awarded the International Award for Magic, commented when he saw this trick: “Absolutely incredible!”
It might be of interest to conjurers that it was a vaguely similar trick that gave rise to the idea. The trick, called the “Domino Box”, was published in the Magic Circular in [...]

The circuit comprises transmitter and receiver, the cable under test linking the two. The transmitter is nothing more than a “LED chaser” the 4011 IC is wired as astable and clocks a 4017 decade counter divider. The 4017 is arranged so that on the 9th pulse,the count is reset. Each LED will light sequentially from [...]

This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011. For the 4017 IC is a 16-pin CMOS decade counter. It takes clock pulses from the clock input, and makes one of the ten outputs come on in sequence each time a clock pulse [...]
