Have to agree with cheenoonions on this one. Great little mashup of some classic tunes. Really good to see someone build a MIDI device then properly demonstrate it with something that actually sounds good.

cheesenoonions:

His choice of what to mashup is awesome.

I love this little scale model. I should probably prototype something similar myself to begin programming our 16x16 RGB matrix.

carbonworkshop:

I put this mini-booth together in order to start programming interactions for our Burning Man installation “Excellent Adventure” while the actual PCBs are being fabricated. The scale figure of me was actually something I made back in college for a large-scale model.

Here’s a quick video of the LED Driver board I posted about previously. This video shows the driver board controlling 16 RGB LEDs cycling through the HSL colour space.

Getting the HSL to RGB conversion to work on a PIC proved a little tricky (most examples on the web assume floating points, or 32bit integers). But after much fiddling I got it working fairly well, though I suspect many improvements can be made yet.

Next we need to make another copy of the board using a PIC with hardware I2C support to help speed things along, and get it made professionally to confirm the design. Then we make a master board to control all these slave LED drivers, and away we go!

There’s some additional videos below:

Just finished making the PCB for a little LED project I’m working on with a friend for BurningMan this year. Didn’t turn out as well as hoped, had some problems with undercutting, and lost a few tracks.

Definitely need to improve the technique. We used the Toner Transfer method to move the toner from a piece of glossy photo paper to the board, then etched with Ferrich Chloride solution.

Initially didn’t heat the etchant but tried to use a sponge to agitate it, I think this probably didn’t help with the undercutting. Plus I accidentally rubbed off some of the toner.

Still, it’ll work for our initial prototype, and give us enough feedback to modify the board before getting it professionally printed.
