Advice needed! Need to re-wire an air pump with special features...

ellbobeee

Hi there,

 

I have a technical 'problem' which a Farnell employee thought might be worth posing to the community on here.

 

I am an artist and I am looking to make a 'breathing' sculpture.

 

I have started by buying a battery operated air pump (designed for mattresses etc.) which has a power supply input bit so that the batteries (7.5V DC 300mA) can be re-charged when the pump is not in use.

 

What I had hoped to be able to do was re-wire the pump to include a) a dial which allows me to lessen the speed of the fan (or can this be done by using lower voltage batteries?) and b) to solder in a sort of intermittent timer so that the fan comes on and off every 5 seconds or so, giving the impression of breathing.

 

If anyone can help with this I would be very grateful! I don't have much of a budget... :-)
