This is a Simple Electromagnetic Ring Launcher Circuit Diagram. The electromagnetic ring launcher is comprised of.four sub diagram: a clock schema (built around U5, a 555 oscillator/timer configured for astable operation), a count-down/display schema (built around U3), a 74190 synchronous up/down counter with BCD outputs that is configured for countdown operation; 

U4, a ECG8368 BCD-to-7-segment latch/decoder/display driver; and DISP1, a common-cathode seven-segment display), a trigger schema (comprised of U6), an MOC3010 opto isolator/ coupler with Triac-driver output; TR1, an SK3665 200-PIV, 4-A Triac; and a few support components), and a reset schema (comprised of Ul, a 7400 quad 2-input NAND gate U2, a second 555 oscillator/timer configured for monostable operation; and a few support components). This schema is that of a repulsion coil (LI) used to demonstrate the principle of electromagnetic repulsion by propelling a metal ring around the core of LI through the air. A countdown schema is provided to count seconds before launch.
