Self-described creative technologist Thiago Avancini hacked this Atari 2600 joystick into a shutter release cable — complete with an autofocus control for his Canon T2i. The controller is considerably larger than the average cable release or remote control, but it’s a pretty nifty. Avancini has more photos of the contraption on his site, but so far, no DIY instructions.

If you’re itching to save a buck and make like MacGyver, Instructables has a handy how-to for a Canon cable release — though it doesn’t look nearly as geek-chic as Avancini’s mod.

It’s pretty amazing how many free learning resources are available on the web for photographers. Recently, BBC Wildlife opened their Masterclasses, and Tamron launched a video series for newbie photographers.

Tripod manufacturer Manfrotto is also dipping into photo education by hosting the Manfrotto School of Xcellence. The program started last Thursday with a webinar led by Bill Frakes, and will continue this Thursday from 2-3 EDT with a lighting webinar held by Joe McNally.

Future class leaders include Roberto Bigano, Ami Elsius, Drew Gardner, Joe McNally, Marc de Tollenaere, Kristoff Ramon, David Duchemin, Jim Oltersdorf and Cliff Guy.

Topics and difficulty may vary, Manfrotto announced, but they will cover tips on video and photo.

The program is free, but requires pre-registration by email.
