As i couldn't bring myself to `splash out` on nice new plastic sheets to then cut and make into a lampshade i was interested in trying out "dan"s comment in his instructable that you could use plastic (HDPE) milk bottles.
I wasn't sure what it was going to go on then i got the idea of using it with an old led torch.
Then came the problem of running all night on batteries!
Along came an old motorola phone charger.
Being pretty illiterate about electronic compatability etc i thought "just give it a go, whats the worst that could happen?" I mean apart from burning my house down.
