StartUps Of Which I am a Principal Technical Designer
- Ubiquity Robotics:
I am the principal hardware/firmware designer for the Magni product which is a 100 Kg payload read to run OEM robotics workhorse so companies can start running and then add their own added value on top of Magni.   The platform is an open source ROS based platform so technical companies can easily save a year of development time and on the order of $60k to 300k development time by starting using our Magni Base. 

Zizmos Earthquake Sensor Network:
I am the principal hardware/firmware/software designer for the Zizmos hardware sensor.  Zizmos is building a system were large numbers of simple, low cost earthquake sensors can be distributed to sites in and around the many cities of the world where earthquake early warning can save many lives and lower the losses of major earthquakes.  

Creativity is the other side of boredom

Once people realize that and overcome the barrier of actually being motivated enough to be creative the world of creativity opens and bordom is put to rest. Try it ... you'll like it!
