An Arduino based weigh scale controller for HX711 modules.
https://maker.pro/arduino/projects/an-arduino-based-weigh-scale-controller-for-hx711-modules
A digital Arduino based weigh scale controller for the commonly available HX711 modules and a load cell. The weight is displayed on a 5 digit display capable of indicating up to 99.999Kg. It uses a TPIC6B595 to drive the LED displays with multiplexing for lower component count. Can be assembled on Veroboard.

Brushed DC Motor Programmable Speed Regulator
https://maker.pro/custom/projects/brushed-dc-motor-programmable-speed-regulator
This article explains how to design, build a low noise high performance low cost brushed DC motor programable speed regulator. The regulator is immune to the temperature, voltage, and motor load variation. Also, this circuit does not care about the motor coil resistance which allows using different motors in one application without any adjustments.
