Building a 1 meter tall RGB LED tower

<< < (3/3)

spuddevans:
Here's the latest episode in the build, assembling all the completed LED PCB's using 16 fiberglass rods and 16 lengths of tinned copper wire. I made up a 3d-printed spacer to help with getting a consistant spacing ( thingiverse link - https://www.thingiverse.com/thing:4910229) and then soldered the 16 copper wires on each PCB, then moved the spacers up a level and repeated until done!!

Once they were all soldered up I went back and superglued about 4 or 5 spots of the fiberglass rods where they go thru each PCB, and this stiffened up the whole structure quite a lot.




Next up will be wiring 3 links (Red, Green & Blue) from each of the 32 "rings" and soldering them to the interconnect PCB.

Thanks for watching,

Here's the next episode in this 1 meter tall saga!!

This time I wire up all the LED PCB's (about 96 wires) to the Interconnect PCB, and also wire the speaker and the Tower-Top LED's to the main PCB.

Then it is time to hold my breath and power it up for the 1st time  :zap:



Next up will be a detailed check that every RGB LED is functioning properly (and then fixing those that are not!!), then tidying up the 98 wires that drop down the center of the Tower. Then a better capture of the various display modes including playing some music-type sounds through it and seeing how it responds to the audio.

Thanks for watching,

So I have finally got this project finished, or at least it is completely built as-per-the-instructions supplied.

The eagle-eyed of you will have noticed that when I tested it on the last video, there was one "ring" of LEDs that was not always showing the right colour, and there was also at least 2 LEDs in another "ring" that were not lighting up in any colour!!

So that's where I begin this time, with fixing those problems/mistakes. Then I tidy up the wiring a bit before testing it again. While this kit is complete, I have got an idea  :proj: to make it a bit better, (which I mention at the end of the video) but that will have to wait a little as there's a couple of other projects I want to do next.




I also made a video just showing the various display modes



Thanks for watching

So I just couldn't leave it be, but hopefully this is the last of this Banggood Canton RGB Tower construction series. (albeit in 4 parts!!!)


In this first part we see what I don't like about the original "as per the instructions" build, and discuss the concept of what I'm going to do. Then we start on bending some LED leads for the very tip of the tower and soldering them up.





Link to the Thingiverse page for the LED rings :- https://www.thingiverse.com/thing:4948458

In this next part I insert the RGB LEDs into the 3d printed rings, and then bend the LED leads to form a circuit.




In this next part I solder wires onto, and then assemble all the levels of the new RGB Tower Tip and glue them in place on the support fibreglass rod.





In this next part I wire up all the connections between the new tower top, and the top existing LED PCB of the main tower. Then after some tidying I show a comparison between the new top and the old one.





That should be the end of this project, thanks for watching.
Tim
