Looking for: Advisor, Biz developer, Designer, Developer, Engineer, Marketer, Product manager, Sales person, Other
The idea is to develop fearly simple products made out of metal scrap. For example you can buy old electrical headphones and develop quite simple new headphone boxes out of it. You would only need a few transistors to build an amplifier.
