I cant give any really helpful advice but a couple of comments

Don't get too precious about keeping the equity. Obviously don't just hand your idea over but a mass producer might want a cut

I don't know where you are but in the UK is a programme called Dragons den. You could go on this although I think your idea might be a bit too techy but at least if you watch a few episodes you will get an idea of the questions they will ask what the money peoples thought process is etc. (Dragons Den was originally Japanese so I assume its world wide now)

Congrats- you actually have something that works!

Here are some suggestions (in order):

1. Protect the IP.

2. MAKE SURE YOU HAVE A MARKET AND CUSTOMERS WILLING TO PAY!! (especially true for this economy)- if you can get conditional orders- so much the better. If you are trying to "push" a technology, it will be a great deal more difficult to get started or even attract an investor or bank.

3. Bring on someone who will help in operations- you might approach high-tech incubators for assistance.

Good Luck
