Prototyping Brief Case Would Be Fun To Take Through Customs

By James Hobson

[Baldor] prototypes electronic circuits all the time, but unfortunately he doesn’t really have a dedicated work space to do this! Annoyed at having to get all his tools ready and then put them away again after every project, he’s come up with his very own electronics prototyping briefcase.

He started with a very old hand-made wooden tool briefcase and added some fun stuff. His case features four breadboards, all with individual positives, and each pair with common grounds. Banana clips allow for various setups with different wiring. He has 5 integrated volt meters, along with 5 buck-boost DC-DC voltage regulators, each set for 3V, 5V, 9V, 12V, and 18V. It’s an ingenuous setup and would make prototyping a breeze compared to most work benches!

In addition to the basic prototyping tools, he’s also got a development board and a place for his Pickit2. Underneath the main prototyping area he stores the power supply, and a veritable army of jumpers. We’re impressed.

Now all he needs is a portable electronics lab in a box once his prototypes are proven!

[Thanks Xavier!]

Electronic Monocle Uses Biofeedback to Track Your Favorite Websites

Electronic Monocle Uses Biofeedback to Track Your Favorite Websites

The internet is a fire hydrant of content. Keeping track of the pages you enjoy is a pain. A team of UK design students has a conceptual solution: Amoeba, an electronic monocle that files away the pages you find most interesting, as measured by your biofeedback response. It’s the emotion-tracking Google Glass you always wanted!

A Light Painting Infrared Ray Gun

By Brian Benchoff

gun

[Noe] over at Adafruit has a really great build that combines the Internet’s love of blinkey LEDs and rayguns with the awesome technology behind extraordinarily expensive thermal imaging cameras. It’s a light painting infrared heat gun, used for taking long exposure photographs and ‘painting’ a scene red or blue, depending on the temperature of an object.

While this isn’t a proper FLIR camera, with a DSLR and a wide open shutter, it is possible to take pseudo-thermal images by simply ‘painting’ a scene with the light gun. This is an absurdly clever technique we’ve seen before and has the potential to be a useful tool if you’re looking for leaks around your windows, or just want to have a useful cosplay prop.

The circuit inside this raygun is based on a contactless infrared sensor connected to an Adafruit Gemma, with the LEDs provided by a NeoPixel ring. There are two 3D printable cases – your traditional raygun/blaster, and a more pragmatic wand enclosure. With either enclosure, it’s possible to take some pretty heat map pictures, as seen in the video below.

Genetic Engineering Produces Desk/Computer Hybrid

By Rich Bremer

Desk Holds Computer Internally

Computers and Desks go together like peanut butter and jelly. After many years of modding computer cases with windows, lights and the like, [Cameron] decided it was time to try something new and combine his next custom case with a desk.

The main desk is from Ikea. The computer case portion is made from wood. No one wants to lose leg room, this case was made to be shallow and wide so it would be out of the way when bolted underneath the desk’s work surface. If any serious maintenance has to be done the case can be easily unbolted and lowered for easy access. Speaker grill cloth is used on the front of the case for 2 reasons; hide the case and keep out the dust.

Computer Desk CAD Design

This project wasn’t just slapped together, many hours went into the concept and design. There are 3 specially designed compartments to keep components separate and optimize the airflow. [Cameron] measured the pre- and post-build processor temperatures and found that the design of the new case resulted in a 15
