Volt Cyclone

Volt Cyclone

High-performance embedded firmware, FPGA gateware, and hardware tooling — from concept to production.


Who We Are

Volt Cyclone builds low-level systems where hardware and software meet: bare-metal firmware, FPGA designs, and the host tooling that drives them. We focus on the hard parts — USB, PCIe, and real-time input paths — with an emphasis on quality, speed, and reliability.

What We Do

  • Embedded Systems & Firmware Engineering
  • FPGA & Gateware Design
  • USB & PCIe Tooling
  • Product Testing & Validation
  • IoT & Connected Devices

Featured Projects

Project Description
Hurra USB HID firmware for capturing, replaying, and injecting humanized input. Documentation
hurra-fpga HID injection using fpga devices.
hurra-app The host-side companion application for the Hurra device family.
PCILeechFWGenerator Generates PCIe DMA firmware from real donor hardware. Documentation
Input-injection-testbench Tooling for evaluating input-injection device behavior.

Technologies We Use

C RISC-V ARM Verilog Python Cloudflare Workers
