Aerospace and defense have historically been dominated by large contractors focused on big budgets and long timelines. Recently, companies like SpaceX and Anduril have shown that speed can be a more effective strategy.
inspectAR brings PCB data into augmented reality, making it accessible on any device. In under two years, we were acquired by Cadence Design Systems, gaining key insights into building, selling, and scaling software for hardware.
Makelab provides on-demand 3D manufacturing for parts, prototypes, and production runs.
Doss builds software to manage your operations from PO to POS all within a single platform.
Steer-by-wire replaces the traditional mechanical connection between the steering wheel and the wheels with electronic controls.
Former founder of Ronin Product Development and current founder of Catalyst Introductions.
Hiring design evaluation engineers is challenging due to the complexity of the technology stack and the diverse skill set required. Engineers must handle chip evaluation and characterization, develop and automate tests, and analyze data to ensure chips meet customer specifications.
Founder of Northwest Engineering Solutions, a PCB design consultancy that also produces excellent content on electronics engineering.
Before the 1990s, the power density of hydraulic motors was approximately a 100 times greater than that of electric motors. Today, that gap is just a factor of 10 with advances in the strength of permanent magnets like Neodymium (Nd-Fe-B).
