I keep this site as a record of a project I am proud of. In my early twenties, while I was skydiving myself and long before AI tools, I reverse engineered Sony's LANC protocol to build K-Mojo, a remote control for helmet cameras, as a side income. There were similar products on the market, so I set mine apart with extra features like a preset zoom position and low battery and tape warnings. It was used in skydiving, snowboarding and other sports. I wrote the firmware in assembler for an 8-pin PIC microcontroller and handled every step of the product on my own: building and soldering each unit, debugging, casing, packaging, the manual, the website, marketing and shipping. I sold about 60 units to customers around the world, and in 2007 I released the firmware and parts list as open source.
