Engineering Contracting Services
About Us
We are a father-Son team of Electrical engineers with experience working on all aspects of electrical product design from concept to production with a focus on Circuit Design & Embeded Firmware. We take concepts and requirements and make them reality.
Capable of doing prototyping and bringup and have our own lab & equipment.
We have a great deal of experience with:
- Control systems
- Motor controllers; drones, ebike
- Automotive Electronics & protocols; CAN BUS, UDS, ISOTP
- Booloaders and secure firmware update
- Automated production testers & PCB diagnostics

Compensation Model
Depending on the nature of the work and the type of project, there are a number of possible compensation models we have used and are willing to discuss, including some combination of:
- Fixed Price Contract - Full-project work with defined requirements and deliverables over a duration of months.
- Hourly/Daily Rate - Small designs, occasional piece-work, consulting, etc.
- Royalty - Working without upfront payment but with the guarantee of profit-sharing if the product goes to mass production. Only for products we believe in.
