OK, so what I want to know is... what do I need to build an IR transmitter - assuming that this is what I need to set off my lap timer.
At Brands in the pit garage, we could set it off with a TV remote.
So can I go down to the local electrical shop and buy some bits to make my own beacon??
If so, what will I need??
I can buy a 'proper' one for £40, but no doubt it's made from 50p's worth of parts.
Thanks ta
