So far electronics were made of commercial parts like the Raspberry B type<\/span>
\nit’s time to boost up the project and use the hardware that is intended for the industry<\/span><\/p>\n

For this, the project is now done with a Compute Module (3B + which is well suited for the necessary power)<\/span>
\nIt doesn’t use SD memory card (the card is limited in terms of access) but an look-alike SSD type memory (emmc)<\/span><\/p>\n

Obviously a micro-controller of the latest technology (2020) is used<\/span>
\nThis in order to use the interrupts (for the security part, among others)<\/span>
\nIt also use the watchdog (this one performs a reset in the event of a bug)<\/span><\/p>\n

It has a 10-bit DAC (REV8) which allows us to make a simple (but better<\/a><\/span>) internal laser tester<\/span>
\nit’s able to generate frames with X\/Y move for 4 primary colors as well as blanking @ 80 FPS (REV8)<\/span><\/p>\n

Filter coils and suppression elements (TVS, etc.) are now part of the project<\/span>
\nThe multiple power supplies have been changed by modern DC \/ DC converters with efficiencies of +\/- 95%<\/span><\/p>\n

New menus will come soon …<\/span><\/p>\n

To be continued<\/span><\/p>\n
