Lights: Light & LED Flash Timer Circuits

Flash you car's headlights on/off, either together or alternatively, with this flashing lights electronic circuits. Don't know if it's legal but it's pretty cool :)

This timer kit contains seven different timing modes using only ONE IC and some support components on a single-sided PCB.

Set this relay-based timer for anywhere from a few seconds to about 15 minutes so that you can time on/off almost anything.

A circuit with 8 LEDs that flash in a somewhat random fashion (well it's not actually at random, but it does visually appear that way).

USB Flash PIC programmer

Timer kits are an ever popular item with the hobbyist. This uses a 555 timer IC and goes from 8 seconds to 8192 seconds.

A bright, variable flash rate strobe light. This is a 9 Volt battery powered xenon tube flasher. A small circut is easily transported for camping etc. Flash rate may be varied between 1 and 4 flashes per second.

The circuit flashes five LED's in sequence repeatedly until you turn it off. Flash rate is user adjustable. The circuit uses an IC chip on Board which you will then mount on the included mother board; battery holder is included. Powered by a 3 volt supply

Timer circuits are handy for many experimenters projects, not to mention the photo lab. This kit has three separate circuits that can be used individually or together. Each circuit has a separate 5 Amp relay. Circuits operate on 9 Volt DC.

An electronic circuit that uses a 556 (Dual timer) IC to produce a two-tone train horn sound effect. Equivalent circuit using two 555 timers (single timers) is given.

A simple circuit that flashes an LED when a cell phone has an incoming call. Uses a coil to pick-up the signal emitted during an incoming call event. Cell phone call detector.
