Hi Frederic, I'm curious as to where you purchased the Annax panel? Thanks for the awesome contribution and write-up.

  Are you sure? yes | no

Frederic L wrote 07/14/2021 at 07:50 • point

Got them on eBay around 3 years ago. Not sure if there have been more for sale since.

  Are you sure? yes | no

Great work on the flipdots. You might want to look at On Semi P/N NCV7719 half bridge drivers - it may help you reduce driver complexity. I use these for my 16x28 flipdot display.

  Are you sure? yes | no

Thanks for the tip, I'll have a look. I slowed down project development since September due to a job change but will soon get back at it !
