We remember making pinhole cameras as kids out of cigar boxes. The Focal Camera website wants to enable you to make sophisticated cameras from a selection of building blocks. We’re talking cameras with film, not digital cameras (although we wondered if you could mount an image sensor… but that’s another hack).
The modules do require access to a laser cutter, and you’ll need to scrounge or otherwise acquire things like mirrors and lenses. The site has advice on how to hack things like first surface mirrors out of cheap items like acrylic mirrors.
The intent is to be able to build up your own cameras from the modules. They do have a pinhole camera, in case you are nostalgic, but you could also build SLRs, large format cameras, or even stereo cameras. Not all the modules are ready yet, but there are several example cameras and pictures taken with them on the site. Like most building blocks, the real treat will be when users begin to combine them in unexpected ways.

[Kyle] teaches photography and after being dismayed at the shuttering of film and darkroom programs at schools the world over decided to create a resource for film photography. There’s a lot of cool stuff on here like mixing up a batch of Rodinal developer with Tylenol, lye, and sodium sulphite, and assessing flea market film cameras. There are more tutorials coming that will include setting up a dark room, developing prints, and playing around with large format cameras.
[hifatpeople] built a binary calculator out of LEGO® bricks or toys. It started off as a series of logic gates built out of LEGO® bricks or toys in the LEGO® Digital Designer. These logic gates were combined into half adders, the half adders combined into full adders, and the full adders combined into a huge plastic calculator. Unfortunately, buying the LEGO® bricks or toys necessary to turn this digital design into a physical model would cost about $1000 using the LEGO® Pick-A-Brick service. Does anyone have a ton of LEGO® Technic® bricks or toys sitting around? We’d love to see this built.
Think you need a PID controller and fancy electronics to do reflow soldering in a toaster oven? Not so, it seems. [Sivan] is just using a meter with a thermocouple, a kitchen timer, and a little bit of patience to reflow solder very easily.
The folks at DreamSourceLabs realized a lot of electronic test equipment – from oscilloscopes and logic analyzers to protocol and RF analyzers were all included a sampling circuit. They designed the DSLogic that puts a sampler and USB plug on one board, with a whole bunch of different tools connected to a pin header. It’s a pretty cool idea for a modular approach to test equipment.
Adafruit just released an iDevice game. It’s a resistor color code game and much more educational than Candy Crush. With a $0.99 coupon for the Adafruit store, it’s effectively free if you’re buying anything at Adafruit anytime soon. Check out the video and the awesome adorable component “muppets”.
