On Saturday I scored 6 metres of UPVC fascia panel for nothing. This is for a Dr who Prop See image -
This may become relevant if I manage to get my head around programming my Arduino to make the prop 'function'.
This will consist of counting from 8 - 0 rounds, detecting that the magazine then has been changed to begin again. Also each shot requires the gun to be 'cocked' using the pump action. Sound and muzzle flash will also be a part of the effect.
In theory Arduino will make this simple, in terms of component count and simplicity and allow for a realistic operation of the 'BFG'.
I have a circuit drawn up that uses 3 555 chips and 2 chips to drive a 7 segment display which will work fine. At this time this circuit has the upper hand......On the Arduino I can make the LED blink, several LED's blink but so far Mr Lightbulb hasn't gone 'DING'
