I take on a few hardware projects a year.
What I do
Preparing a design for mass production. I change a design so a factory can build thousands of units the same way every time. I run tolerance analysis so the parts still fit when each one is slightly off. I choose factories and hold them to the drawings. I have run builds in Shenzhen and Taiwan and worked on the production line during them.
First working prototypes. Mechanical design, how the parts fit together inside the product, and building the prototypes.
Wearables and head-mounted devices. Mechanical design and optics, including waveguides, small displays, flex circuits and heat management.
Interim head of hardware. For software companies building their first hardware product. This is a longer engagement.
End to end
I can run a product from first prototype to mass production. I do the mechanical design, manufacturing and optics myself. For electrical design and firmware, I either do the work or bring in engineers I have shipped products with. I stay responsible for how it all fits together.
If a project needs skills I do not have, I will tell you early and recommend someone who has them.
Confidentiality
I do not share who I have worked for beyond what is on this site, or what they are building. I worked on an unannounced product at Apple for nearly five years without discussing it. I treat client work the same way.
Contact
Tell me what you are making, how many units, and when you need them. I reply within two days.
