Hardware product developer. Founder of Arc Instruments. Team Lead Software Developer at Nocland. Computer Engineer. Design, prototyping and manufacturing.
I've worked for three years to bring a new concept for an electronic music instrument to market. I've learned the hard that while the broad lean values hold true for hardware products - many lean tactics do not directly apply. I can guide you in creating conceptual 3D drawings, assembling a team, creating working prototypes quickly and cheaply, usability testing, reliability testing and designing for manufacturing.
HAXLR8R would be my pick (http://www.haxlr8r.com/). 111 days in Shenzhen, a San Francisco launch day and reasonable funding (25k-100k) for a small equity stake (6%-9%). The time in Shenzhen would be very valuable if your team doesn't have experience manufacturing in China.
