Multiple flickering flames circuit using LEDS

This circuit randomly flickers 8 yellow LEDs to simulate multiple flames. This circuit can be used to simulate old style gas lamps or a burning building. Selectable mode selects between continuous running or one by one start up and shutdown. Using the one by one startup / shutdown mode allows you to simulate a burning building starting on fire then being put out. Read more....

Multiple campfires circuit using LEDS

This circuit has a total of 4 random flickering campfire scenes. Each of the 4 campfires contains one flickering yellow LED for the flame, and one pulsating red led that simulates the glow of the embers in the fire. Read more ...

Police or emergency vehicle lights circuit using LEDS

This circuit has outputs for 2 red LED strobes and 2 blue LED strobes that simulate a modern police car, fire truck or emergency vehicle strobe lights. The red LEDs strobe quickly 3 times, then the blue strobe quickly 3 times. The circuit also has outputs to drive tail lights and headlights as well. The headlights can be set to be always on or have alternating wig-wag flash pattern.  This circuit can be set for either random or continuous operation. Read more...

Welding and industrial scene circuit using LEDS

This circuit contains an output for a LED that simulates welding, a LED that glows like glowing iron , a campfire/barrel fire, a blinking LED that can be used for a neon sign simulation, and a flickering LED output that simulates a burning out neon or fluorescent sign. All 4 circuits are contained in one chip! Read more...

Airport beacon circuit using LEDS

This circuit contains 4 outputs that drive 4 LEDs with one of the following selectable beacon looks; Fast strobe, slow incandescent beacon look, double blink beacon look. This circuit is used to simulate the look of lights on the top of TV towers, water towers or buildings by an airport scene. Read more...

Animated house lighting circuit using LEDS

This circuit drives 6 white LEDs, with each one periodically turning off to give a lived in look for model railroad buildings. Use this circuit to drive the white LEDS that light up the inside of your buildings on your model railroad layout. The circuit also drives a blue LED that simulates the look of a TV inside a building. Read more ....

Simulated Fireflies Circuit using LEDS

This was based on a project I did a while ago to simulate the look of fireflies in my garden. This circuit drives 8 yellow-green colored LEDS to simulate the look of fireflies. Each LED randomly blinks on quickly then slowly dims out to simulate a firefly in the evening. This is a very slow effect as only 1 or 2 LEDS blink at a time. The time between blinks can be greater than 30 seconds. Recommended to use small 3mm LEDS. This circuit is perfect for a forest scene near the campfires on a model railroad layout. The circuit can also be used outdoors in a garden when weather protected properly. Read more...
