I'm impressed. About 150 quid all in. DPA can't write a one-line email for that. How much do you think the project would have cost if they had been in charge? Plus, of course it wouldn't work half as well as this.
Now all we have to is hook it up to an explosives sniffer and stick them outside bus shelters and underground stations.
That's not a walt! That's a seriously intelligent kid having an interesting idea and getting off his arrse and actually making it a reality. Fair play to him, and I hope he ends up getting a well paid job contract out of the exposure he's getting.
On a note, I wish I had the brains to come up with something like that. I'd love to fit one of those to cover my driveway and stop the little chavs coming anywhere near the motor!
