Hyperionus: First Thoughts on LED Strips

So, I got the LED strip I ordered from SparkFun that I mentioned in my last post.

Turns out, its really cool and pretty damn bright.  Pictured at the right are full-intensity brightness representations of Magenta, Yellow, Cyan, White, Red, Green, and Blue as captured with my Motorola Razr’s camera phone.

It took about an hour or so to get blinkin’ lights with some electronics I had laying around.  Fully illuminating the strip takes 1.8 amps at 5 volts!  And, it seems super bright.  I’m actually not sure it will be bright enough to project on a white canvas in a lit environment, though, so I may have to use two or three of these.

I’ll be moving into the DSP stuff next now that I have a platform talking to the strip making it blink for development.

Oh! And, Raspberry Pi, the $25-$35 ARM-booting-Linux board project has announced that boards will be done soon:

…the boards will be finished on February 20.

Somehow the project managers convinced Broadcom to release a peripheral datasheet for the BCM2835 SoC that the Raspberry Pi is built around, enabling legitimate kernel drivers to be written for the peripherals!  Just imagine… a development kit/embedded computer that comes with a datasheet for the SoC?  Unheard of!

    Thanks Amanda! I’m working on it this weekend and this week, so we’ll see how it goes!

    There’s actually this hobbyist competition at work for R&D folks coming up in April I’ve entered it in. So, I don’t really have a choice for it to be good or not, now!
