README
README.mdtd-crt
This repo contains work-in-progress electronics to control a CRT monitor (aka a CRT chassis).
It is divided up into several separate projects, as follows:
-
td-deflect - Main PCB, containing microcontroller, horizontal and vertical deflection circuits, RGB amplifier, B+ power supply, 12V and -12V power supplies, and heater power supply. Functional with an enormous amount of rework.
-
td-hv - Regulated HV/focus/screen power supply, based on K7000 clone flyback. Currently marginally functional, demos were done with the original monitor's HV.
-
td-rgbinput - Poorly named RGB amplifier that replaces the version on td-deflect, using more modern parts. Currently untested.
-
td-180v - 180V (and heater) boost converter, designed to be installed on a neck board to provide an optional dedicated power supply for the cathode amplifiers.
-
td-rgb - Old RGB mod PCB, I should move it to a separate repo at some point.

Questions
How big is the Td deflect PCB?
It measures 174 × 104 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Td deflect use?
175 parts, built around the R-78B3.3-2.0, IRS2005SPBF, BD9G341AEFJ-E2 and MIC4427ZM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Td deflect KiCad files?
From the tdaede/td-crt repository on GitHub, at the commit this page was made from: the board is td-deflect/td-deflect.kicad_pcb and its schematic td-bplus-psu-gan/td-bplus-psu-gan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Td deflect design in my own project?
Its repository states no licence, so its author keeps all rights: ask tdaede before reusing the design.
