Hi Brett, I've been using your site for a while now. It's fantastic. I own several slave clocks from Siemens, Bürk, RFT, Peweta, and Pragaton. The slave clocks all require 24 volts. I've recreated the Arduino Pragotron Master Clock with a UNO, and it works perfectly. It's great for the second clocks, but how do I get the code to output minute pulses? I've already commented out and re-commented the sketch, but I haven't gotten anywhere. Perhaps you'll have the time to help me.

Best regards, and thanks for sharing your projects.

Hi,just seen your awesome cyclotron clock.It is absolutely amazing. Would like to know how much it would cost (if applicable) For you to build a unit for me?

I entered the wrong email address.
Thank you for this DIY project.
Is the programming switch a push button or a switch? Is the pin permanently grounded when the watch winder is running?
Thank you in advance.

Greetings Brett, Enjoy the LED Wordclock. I made it with a fully 3d printed front diffuser. Printed it on a Bambu with an AMS for two colors. I would be happy to share it with you if you wish.

I do not have a local NTP and it appears one is required to have the clock update each minute. Also, the seconds display along the bottom does not work. It appears to be stuck on the seconds when the clock reset.

The RTC synchs and sets the clock when reset by power or 2 second button push but does not update the time while running. I selected animations and seconds update on the website when I set it up so I would expect the seconds to update.

Any help would be appreciated. Thanks.
