Great Kit
Just finished one of five I bought, took less than an hour to complete. I bought these to make railroad crossing signals , but am trying to figure out how to display them without the board showing?

R/c quad flasher
I purchased this to use as a flasher for the led modules sold here on my r/c quadcopter. I am running this on 12volts and bypass the 1k resistor since the modules can run on 12 volts. This makes the orientation of my quad much easier to see even in daylight, looks like a UFO at night. It always attracts onlookers in the dark.
