Push-Button Opening Mechanism for countspatlua's Ghostbusters Trap

I am rubbish with electronics and couldn't afford the full system anyway so decided to design a push-button mechanism for countspatula's amazing ghost trap model instead, so my 8 year old son could enjoy it a bit more when he's catching his ghosts.

I have revised a few of the original parts and made some new ones.
You will also need a few screws and 4 springs (detailed in the instructions pdf included.

Please post a make if you decide to make ti too. I'd love to see others enjoying my creation :)
