This 16x16 LED Matrix has a newly designed 3D printed grid. Compared to my previous 32x32 LED Matrix the grid is improved to separate the light of each pixel. Standard WS2815 LED Strips (60LEDs/m) are used. The diffusor is a Polypropylene foil and is slided into the grid.

This is lovely, the production, the everything about this. The music has me in my zone right now.

Thanks 🙂

Wow! Thank you. I'm thinking about buying a 3D-printer and make this my first project. Thanks!

@yotudero 2 месяца назад

Thanks! A 3D printer is a really nice tool. There are so many cool things to print.

@wasdaletimelapse7658 2 месяца назад

Exquisite as always. I really like the solution for the diffuser, well done. I wish I could justify a 3D printer...

@yotudero 2 месяца назад

Thank you! I thought a lot about the grid and the diffusor and came up with this solution. I refused to buy a 3D printer for a long time but now I can't stop printing. It is so much fun :D

@mikes78 2 месяца назад

@@yotudero The number of times I've thought "I really wish I could do . . . " and then remembered I can make something with a 3D printer that if it doesn't fully fit the bill of what I want, it can come awfully close is something that I have lost count of. From replacement brackets in kids toys, through statues, mounts, ducting for fans, hinges and countless other things, having a 3D printer has proven itself invaluable..

Nice work. Please make a video on how you generated the patterns

@yotudero 2 месяца назад

Thanks! These are the standard animations available in WLED. Just programm your controller with the WLED Firmware and select the different animations. Check the link in the description for the WLED web page and the installer web page.

Honest question: is the aluminium base plate, heat-sink necessary, or extrusion along the edges necessary?

@yotudero 2 месяца назад

I think the aluminum base plate is necessary. Without the heat sink the temperature slowly increases to roughly 40°C in 30min. After 30min it gets really hot. That's why I added the heat sink. The extrusion along the edges is not for cooling. I just like the clean look, it makes it easy to mount the LED Matrix to the wall and it protects the electronic parts on the back.

@SeanLumly 2 месяца назад

@@yotudero Thank you for the thoughtful reply. The plate and heatsink seem to be good design choices, as does the extrusion given its aim.
