Benchoff Design Portfolio

Hardware, Embedded Systems & Strange Projects

I design, build, and reverse-engineer hardware, embedded systems, and unconventional tech. My work spans low-level firmware, PCB design, industrial design, and creative problem-solving—whether that’s modernizing a 1970s electric car, designing a $15 Linux handheld, or reverse-engineering legacy consumer electronics.

What I Do Best:
✔ Embedded Systems (RP2040, STM32, AVR, Linux SBCs)
✔ Hardware & PCB Design (High-Speed, CAN Bus, DAQ, Power Systems)
✔ Industrial Design & Manufacturing (3D Printing, CNC, Injection Molding)
✔ Reverse Engineering & Hacking (Legacy Hardware, Retrocomputing, UI/UX)

Featured Projects

Coding

🔹OrthoRoute – GPU accelerated autorouting and it’s a KiCad plugin
🔹Babelscope – A massively parallel emulation framework that found absolutely nothing
🔹Finding Atari Games in Randomly Generated Data – 30 billion ROM files and only one broken game
🔹A port of Mbed-TLS for the Classic Macintosh OS 7/8/9 – SSL/TLS for something that was never meant to have it
🔹Embedded SSL and GZIP – Because you don’t need to run everything in Linux

Embedded & Open Hardware

🔹 Exaluminal – An IoT device to detect supernovas up to an hour before the Earth is destroyed
🔹 Multi-Stop Bus Tracker – When is the next bus coming to many different bus stops
🔹 The $15 Linux Machine – A fully functional Linux handheld for under $15
🔹 Isolated Thermocouple Reader – A low-cost alternative to a $2,000 industrial module

Reverse Engineering

🔹Reverse Engineering Nvidia’s SXM2 Socket – Because I had to do it for another project
🔹Copying 20 year old USB devices – When you can only find one on eBay

Restoring & Modernizing a 1970s EV

🔹 The Citicar Restoration – Bringing a vintage electric car back to life
🔹 Car CAN Bus Conversion – Replacing all relays & analog systems with a CAN-based network

Retro Tech

🔹 BaudBox: A 256-Key ASCII Keyboard – A serial input device for manual debugging & obscure ASCII characters
🔹 Rebuilding a Zip Drive Tower – Stacking fifteen ATAPI Zip-100 drives into a USB RAID array

Industrial & UI/UX Design

🔹 Custom Silicone Keyboards – Designing low-cost, high-durability keyboards
🔹 Full-Color Circuit Boards – Experimental multi-color PCBs beyond standard manufacturing
🔹 Portable Dumb Terminal – A VT100-style ANSI terminal in a pocket-sized form factor

About Me & Work

I specialize in building functional, practical, and sometimes ridiculous hardware. My goal is to design great products, solve difficult engineering challenges, and push the boundaries of low-cost, hackable, and open-source hardware.
