Led indicates wallet is empty - Wallet Idea ! Answered

I had an idea for a wallet instructable, In the section of the wallet where you put the notes there are two metal connectors that touch when there are no notes but the connection is broken when a note is inserted, when the circuit is completed (wallet empty) a red led on the outside lights up indicating you need to go to a cash point and get some more money. Do you think this is a good idea ? should i make it ? What extra features or improvements would you like to see ?

Ok, perhaps it is not done in the UK, but in the states, the ink is slightly metallic i.e. conductive in nature.....something would need to be done differently (on this side of the pond), so your batteries were not in constant drain.

Ah yes. Kiteman's law. Say, how much are those t-shirts with that printed on it?

Sounds like a neat idea for sure. I'd put a fake petrol meter on there, with a needle from "Empty" to "Full".

This sounds great. Add a small piece of metal as a spring to put pressure on the contacts and you have a very functional product. Then market and sell, sell, sell!!! I get 15%
