Phase 4 Analog Drive
About the Phase 4 Analog Drive PCB
Phase 4 Analog Drive is an open source PCB design by raffcorreia, published on GitHub under the MIT license. It is a 2-layer board measuring 85 × 45 mm, with 17 components from 11 distinct parts.
Other key parts include the MC74HC4066ADTR2G and 74LVC1G66LT05ARCQ. By type, the board carries 10 resistors, 3 capacitors, 2 ICs and 2 connectors.
From the project
REST API and local touch UI for invasive control of Samsung CJ791 monitors by electrically emulating the front-panel JOG button. Uses an inline hardware mod on the JOG harness and DDC/CI for feedback, status, and supported monitor functions like input detection and power control.
samsung-jog-api is a hardware-and-software project to make a Samsung CJ791 monitor locally programmable by electrically emulating its front-panel JOG control, exposing that behavior through a local REST API, and hosting a touch-first local control interface on a Raspberry Pi-based control deck.
This repository is organized around the Samsung LC34J791WTNXZA / CJ791 hardware in my setup. Related Samsung monitors with a similar multi-jog front-panel board may be adaptable, but the measurements and assumptions here are specific to this unit unless noted otherwise.
