If that scenario sounds all too familiar, consider PolyServe Matrix Server, which combines a robust cluster ...

Copied four-fold, this circuit joins the rows and columns of the 74HC595 to the keypad matrix. To scan across the four columns, the microcontroller performs an SPI transfer of the key value: 0x01.

[Faire-soi-meme] prettied up an 8×32 NeoPixel matrix with some diffusers and a grid bezel. It’s the ESPMetric , and it’s also an entry for this year’s Hackaday Prize.

Simple Matrix Multiplication Accelerator in SystemVerilog - Work in progress. An attempt to make a lightweight, FPGA-compatible systolic array-based matrix multiply engine inspired by Googles ...

This Design Idea demonstrates a simple way to turn a step input into a ramp of nearly constant slew rate. The basic circuit uses a single op-amp; a circuit built on an integrator will typically ...
