Rui here,

I’ve created this page to share some awesome messages that I’ve received from people all around the world which I’ve helped with their own projects… I’ve tons of messages to share but i’ll only post a couple of them!


Hi Rui, thanks for this great led cube tutorial.

I have just finished building the 3x3x3 led cube, I used the smaller 3mm ones because that's all I had and it was very tight inside that cube 🙂

Many thanks again.


- John Berry


you're a geneous! Followed your instructions and my Cube works like magic! Thanks a million. All I need to do now is learn how to program my own patterns, then I'll move onto a 4x4x4 cube. Lot's to keep my 75 year old brain active.

Thanks again,


- Ray Gascoyne

Hello Rui,

I am so pleased to tell you that I tried

your new code in the Arduino distance

project and it works great. It does everything 

that I wanted and I really appreciate all your help.

 I plan to go through it and try to understand the code.

 If there is anything I can do to help you out,

just drop me an email.

Thanks Again!
