Featured Embedded Systemscategory FPGA Wordle: Building a Complete Game Console from Transistors to TouchpointsA deep dive into the design and implementation of FPGA Wordle, a fully hardware-implemented word-guessing game that runs on a custom five-stage pipelined MIPS processor, with real-time VGA display and PS/2 keyboard input — all built from first principles in Verilog and assembly.FPGAMIPSVerilogWebAssembly
Featured Biomedical Engineeringcategory Embedded Systemscategory EOG Sleep Mask: Detecting Secondary Sleep Strokes in Real-TimeA wearable, real-time stroke detection system disguised as a comfortable sleep eye mask. By utilizing electrooculography (EOG) to track eye movement and an onboard microcontroller to perform real-time signal processing, the device acts as an automated sentinel.ArduinoOp AmpEOG
Biomedical Engineeringcategory Embedded Systemscategory Isolating the Corneo-Retinal Dipole: Building a Robust EOG Analog Front-EndThe human eye is a natural dipole. The cornea carries a positive charge while the retina is negatively charged, creating a resting potential of roughly 10 to 30 millivolts. The raw voltage potential reaching the skin is attenuated to the microvolt range and completely drowned out by surrounding electromagnetic interference (EMI) and electromyographic (EMG) muscle noise.Intermediate29 minutesMay 30, 2025ArduinoOp AmpEOG
