Maker Faire Project Update: Grow Lamps![]() Over at Darker Technologies they're making good progress on the Maker Faire projects that we're exhibiting in the same booth this May. The first LED grow lamp array has been built and tested. It uses red and blue LEDs, since those are the wavelengths plants absorb (they reflect green, so no need to waste power emitting that color). He'll be testing the arrays on live plants this month, using other light sources as a control. If you're in the SF Bay Area this May, stop by the Maker Faire in San Mateo and check out all the great projects and exhibits! There's a lot to do! It's fun!

I built a device that has the potential to drive a computer user insane. This device plugs into a USB port and implements a USB HID keyboard. Instead of doing anything useful, it waits between 30 seconds and 8 minutes and sends the scancode for the Caps Lock key. This will toggle the Caps Lock status on or off. Since the operating system controls the LED on the keyboard, the Caps Lock light also toggles. This makes it appear the user has accidentally pressed the Caps Lock key...until it happens 20 or 30 times and they get suspicious. Then they might see the Caps Lock light turn on by itself. Next is a sequence of reboots, bashing the keyboard on the desk, clicking through the Control Panel, possibly even replacing the keyboard. Unless they notice the tiny little device sitting in one of the USB ports on the back of their computer, nothing will help. Read more» Submitted by Garrett on Thu, 04/03/2008 - 16:02. Ball throwing robotI like this ball throwing robot and the dog operating it. Unfortunately I can't find any build details, it looks like a lot of work was invested in the mechanism and controller.

Project: 16x24 RGB LED ArrayThis project is an array of LEDs, sized to fit an alcove in my apartment living room, about 35 inches wide by 58 inches tall. The LEDs will be RGB, with fullcolor pixels arranged 16 wide by 24 tall. Each pixel will be 2 1/8 inches square. There are a total of 384 pixels, and 1152 individually controlled LEDs. The array will be used to display informational graphics, audio visualizations, and tunable ambient lighting. Read more» Submitted by Garrett on Sun, 03/09/2008 - 18:49. Project: ShiftBriteShiftBrites in stock now. Click here to purchase online.
ShiftBrite is a simple device I am designing and producing. It allows easy control of a bright RGB LED. The interface is a straightforward clocked serial data line and a latch input. All signals are buffered and passed through for good performance over long cables and daisy chaining many devices. Many ShiftBrite devices can be controlled from any type of controller that supports clocked serial data output, which is practically all microcontrollers and even PC parallel port or FTDI bitbang adapters. The above images are renders of the revision 1 design. These were created by exporting PCB images from Cadsoft Eagle, and using the images as textures in a Sketchup model.

Lots of interesting parts, gizmos, tools, and random clutter. Click on the photo above to view my Flickr set of the event! Submitted by Garrett on Sat, 03/08/2008 - 20:25.
