@openhardware-io That looks great! - Perhaps they could make a version for the UK market called "regnsyn" ??? ;0

@tlustoch The node is a very simple one. So I never considered boot loaders, as the node would not need changing sketches during it's lifetime. I have boot loading functionality on my other designs, this one is a minimal board. Any extra chip would beat the purpose of the word "minimal". It's a dumb node for a reason

@KevinT every time, yes. I don't know the relation to processing.

Lovely work. Are you proposing to sell the boards? SMD looks too hard.

To provide a large enough pulse to drive the ceramic transducer , you need a lot of energy, so they pump up the 5v with an inductor/transformer to provide a high voltage pulse. This is 60v or more… The more Energy you produce the farther the pulse will travel…. Everything thing else on the board run at 3.3 to 5V. Add a large Capacitor of 100 µF are so between the 5v and ground on the device, this may clean up your problem.. Some CPU modules just can’t supply enough current quick enough that’s needed when the pulse is triggered. These are very inexpensive device, we’re luck to see them work at 1/2 the spec range.

Hi! I have the same problem as terxw. allpcb.com is missing the "NC drill date". Unfortunately I am not able to create this on my own. Can anybody upload this file? Thanks

Awesome project, I wish I made something like this. (I actually wanted to make something like this when I was in school) Very clean and nice presentation and realization, with a lot of attention to details. All is very realistic, I can imagine that it took quite some time making it. Thanks for sharing the details!

With how long max tape you test it ? I have a living room and i need control RGBW with about 16 meters.... I can use your controller ?
