Predictable Designs with John Teel

I teach how to develop and manufacture new electronic products. I'm a former microchip design engineer from Texas Instruments, where I designed chips used in millions of products, including devices from Apple. I also developed and launched my own hardware product which sold in hundreds of retail stores, so I understand the entire journey firsthand. On this channel, I share everything it takes to go from concept to production including prototyping, PCB design, enclosure design, certifications, and manufacturing.
