This module simulates an Arc Welder in a maintenance shed.
The random flashes from the 20,000mcd white LED appear very realistic.
The module contains 2 microcontrollers and a white LED on 300mm supply leads
to connect to a 9v to 12v DC power supply.
Two opaque panels are also provided for the window of the model shed to
provide the realistic flashing effect.

Question from a customer:
Can I add a BLUE LED?
The module is supplied with a 20,000mcd white LED but you can add a blue LED
too. The module is supplied with 2 diffusion screens spaced apart at 5mm to
give a diffused effect.
All the LEDs on the board are in series and absorb 9v so if you add a Blue
LED you will need a 12v supply. 2 LEDs have micro-controllers and the white
LED drops 3.2v and a blue LED will drop another 3.2v - making 12v needed to
get the full brightness and about 10ma to 20mA current consumption.
