The folks at The Geek Group built a camera crane for less than $1000. In the video embedded after the break a presenter takes you through the different parts that make up the boom and how it is operated. This feels like something from a Junkyard Wars challenge as most of the parts are scavenged or from an industrial surplus store. Don’t let that sour your opinion, what they’ve ended up with is amazingly functional.
The base of the unit is a rolling tripod used for television cameras from around the 1960’s. The aluminum boom attaches to the base with a few large bearings and features a fine tuning balance system. The camera mount is motorized and can be moved using a joystick or set to scan automatically. It’s nice to see more examples of custom camera mounts. Obviously this isn’t a build for everyone, but as cameras and camera equipment become more readily available it makes high quality video production available for the masses, not just the networks.

[Satiagraha] let us know that Texas Instruments(TI) has given out a neat “LED Reference Design Cookbook” PDF. The document contains 17 some odd little projects featuring different TI ICs and ways of using them to control LEDs in things from backlights to torches to solar lanterns to advanced PWM control! Sure the document is biased towards using TI equipment, but that shouldn’t stop you from recreating, modifying, and generally just having fun with their designs in your own productions.
mbed is a next-generation 32-bit microcontroller platform. It’s a prototyping and teaching tool somewhat along the lines of Arduino. On steroids. With claws and fangs. Other contenders in this class include the MAKE Controller, STM32 Primer and Primer 2, Freescale Tower, and Microchip’s PIC32 Starter Kit. The mbed hardware has a number of advantages (and a few disadvantages) compared to these other platforms, but what really sets it apart is the development environment: the entire system — editor, compiler, libraries and reference materials — are completely web-based. There is no software to install or maintain on the host system.
