No, I haven’t burned my 512 RGB LED coffee table (yet)..

No, I'm still alive and no, haven't turned my coffee table into a big camp fire (yet) 🙂 I was just busy with renovating my flat and some other projects that I'll show you in some future blog posts as well. Therefore I didn't had too much spare time left that I could invest into my 512 RGB LED coffee table project lately. Still I want to give you a brief update what has happened in the meanwhile: I closed my last blog post with basically having the table hardware-complete but still not finally assembled to be able to fix any hardware related bugs that might show up while continue testing it. For some weeks I've left the table in that state, did test various things and fixed some bugs before I put it together and moved it over to my living room where it just does it's job as a good looking coffee table. Since I can't use my notebook to connect to the Rainbowduino V3 controllers any more I had to spend some time on getting my Java software easily deployable to the tables PC and to add a hook into the Linux installation so that it starts up while the PC is booting. Feel free continue reading if you're interested in the details on how I did that and to get some additional insight in the current state of the tables Java software.

The first test assembly of my 512 RGB LED coffee table

After being busy for almost one year with constructing my RGB LED coffee table it has finally happened: The almost complete table assembled in its full beauty! Wow! Pretty impressive to see everything together working for the first time. Okay, some hardware isn't fully done yet, the software is in an early prototype stage and still some bugs have to be fixed until I'll move to table from my shop to the living room. Nevertheless I'd like to share this moment and the current state of my project with you.

A closer look at the RGB LED coffee table internals

Since my last post about the audio system installation of my 512 RGB LED Coffee Table project I've spent my time finalizing the table internals needed to operate the eight LED arrays inside the coffee table. This includes the power supply, the micro controllers used to operate the basic table functions, the Mini-ITX PC that generates and distributes the to be shown images to the eight LED arrays as well as the needed wiring between the individual components and the front panels used to operate the table.

Soldering 512 RGB Leds: Pure fun… Not!

Finally! After hours spend with fitting LEDs into reflectors, preparing cables, cutting shrink tubing pieces and soldering everything together to 8x8 LED arrays: It is done! And I'll never ever do it again this way. 🙂 As I already stated in my first blog post about my 512 RGB LED Coffee Table project I was a bit too optimistic in the planing phase regarding the wiring effort needed to get all LEDs working.

Howto waste your spare time: Build a 512 RGB LED coffee table

"Wait.. What?! Are you serious?" "Yes, I am!" "Why do you want to do that?!" That's actually a very interesting question - and it's the usual response I do get if I explain what it's about those weird pictures I post on Facebook about prototyping loudspeakers or drilling 2,560 holes into plywood boards. Also people don't quite understand why I've spent hours and hours with constructing a 3D model of a coffee table. This is a first attempt trying to explain myself why I'm spending my free time for this project since more than 6 months now.
