Engineering services

Electronics, firmware and the software around them, designed by the engineer who builds the VHRD products.

Availability

Right now most of my time goes into our own products: Donguru, rePort, the CAN line and the software tools. I take on outside work only when a slot opens up, so I can’t promise a start date.

You are still welcome to get in touch. I answer every message, even if it is “not right now”. Sometimes a short call or a pointer to the right part is all a project needs.

What I do

  • Board design. Schematic and layout in KiCad: mixed-signal, power, USB, CAN FD, Ethernet with PoE, isolated interfaces.
  • Embedded firmware in Rust. Bare-metal drivers and real-time firmware for STM32 and other microcontrollers, no-std and no-alloc.
  • Device communication. Typed, versioned protocols between a device and a PC with WireWeaver, my open-source protocol and code generator.
  • Desktop and test tools. GUIs, test jigs and production flashing for your boards, built on the same stack as IOWeaver and RockFace.
  • Power and motors. BMS, power stages, 6-step and FOC motor controllers.
  • Design review. A second look at your schematic, layout or firmware architecture before you order boards.

Examples of this work are on the work page.

How I work

  1. You tell me what you are building and what you need.
  2. I answer honestly: whether I have a slot, a rough estimate, or who else could help.
  3. If it’s a fit, we agree on scope and milestones. You get the design files, the source code and the documentation.
