IPhone 4 Steadicam

July 20, 2010 by 25 Comments

It’s been a while since we’ve seen a steadicam, and to quench our thirst is this  iPhone 4 steadicam. The system does use the typical 3 axis PVC gimbal and heavy weight setup that we’ve seen before, but (why has it taken so long to get this implemented?) the addition of a hand grip means you no longer get blistered fingers. The tutorial recommends the use of an expensive cup holder mounting system, but we think making your own epoxy one might save another dime and allow a wider range of cameras or phones.

The whole process is also wrapped up in a quick and simple how-to video (after the jump alongside an in action video), which goes to show even though a hack may have been done several times before, presentation can make a big difference and impact.

Rapid Furniture Prototyping

July 20, 2010 by 11 Comments

SketchChair is a piece of software that takes the engineer out of engineering furniture. In a child’s-dream-come-true you draw the outlines you’d like to have, add some legs, and the software pops out a design ready to be laser-cut. The finishing touch of adding palm fiber and felt produces what we imagine is a moderately comfortable place to sit. Now the hard part will be convincing your spouse that you should spend the money building an industrial grade laser cutter because of all the money you’ll save on furniture.

We’re still holding out for furniture that is 3d-printed from rock to match our Flintstone’s motif.

Oh, and as always, video after the break.

IPad Arcade Dock Has Hidden Projector

July 20, 2010 by 18 Comments

This iPad dock is a well-executed gaming accessory. [Linkreincarnate] used a Hori Wii fighting stick as the controller. In his hardware explanation he outlines several benefits of this choice including built-in support in most of the iPad emulators, as well as foregoing the need for a wired connection. Just above the controls there is a standard docking connector which holds the iPad in place and patches through the audio to some external speakers. But  that’s not all that is included in the build, the final touch is a pico projector that can be used if you want a larger gaming experience. Video of the hardware and a gaming demonstration can be found after the break.

Hands-free Input

July 20, 2010 by 8 Comments

This is a concept input device that [Tech B] built for disabled users. The device uses an accelerometer along with a piezo sensor (right click) and a push button (left click) to function as a mouse. The Arduino that resides in a breadboard on the side of the hat communicates with the computer over a serial connection, using PySerial to translate the microcontroller data into cursor commands with the power and ease of the Python programming language.

During development [Tech B] made a proof-of-concept video using a Basic Stamp which you can watch after the break. He found that this input device was less complicated, more accurate, and much less resource intensive than his webcam IR tracking system.

4-player SNES And More

July 20, 2010 by 18 Comments

[Mr.X] added support for four controllers to his Super Nintendo (Google translated) by internalizing the multi-player adapter. In the video after the break you’ll notice that he also added some bling to the case by positioning the power LED beneath the logo and adding a two-digit display. There is a switch on the back that allows him to choose PAL or NTSC standards with the current setting shown on that display. While most people are going with emulators, [Mr.X] ended up with a custom piece of hardware with a clean finish.

Wifi Hotspot Powered By Wind Turbine And Solar Panel

Students at the Rochester Institute of technology have put together this WiFi hotspot that is powered by a wind turbine and a solar panel. It gets its signal through a parabolic antenna pointed at a near by building and repeats it for use in the vicinity. They are using a 30W solar panel, along with a 1/4 horse power 90V DC motor to charge two 6V batteries in series. On a windy day, the turbine has yielded 120W. Something interesting to note is a comment they made about blades. Though the ultimately decided to mimic a commercial design for wind turbines, they found the most efficient to be a single wood prop. Unfortunately, that prop was destroyed.
