ESP32 touchscreen and HMI builds, single board computer reviews, and the custom enclosures that finish them: 3D printed and CNC machined in aluminum.
I build real embedded systems start to finish and show every step: ESP-IDF and Arduino firmware, LVGL interfaces in EEZ Studio, CAN bus, custom PCBs in KiCad, enclosure design in FreeCAD, then 3D printing and CNC machining, including a DIY 4x8 LowRider V4. Code, wiring, and docs are open source on trailcurrent.com and GitHub.
Reviewed so far: Waveshare, Elecrow, Makerfabs, Radxa, Raspberry Pi, and Arduino. Every review is a real build, with honest results.
Home of TrailCurrent, an open-source platform that makes any vehicle smarter: displays, power, GPS, solar, and sensors on one CAN bus, tested in an RV.
Manufacturers: US-based and open to review units and collaborations on dev boards, displays, 3D printers, filament, CNC machines, and tooling. Some links are affiliate links.
