Tool Review: Q Knot Reusable Ties
I was very interested when I got the PR about the Q Knot reusable rubber ties from a company called UTWire. They work on the same principle as standard plastic zip-ties but they can be fairly easily pulled apart and reused. If you crossed a rubber band with a zip-tie, you’d get a Q Knot.
Arduino-Controlled CheerLight
CheerLights is a project whereby lights the world over respond to social media like Twitter hash tags, linking the real world to the online world. Pete Prodoehl created his own CheerLight with a ShiftBrite module and Seeduino.
Collin’s Lab: DIY Contact Mic
It’s amazing what a little disk can do … when it’s layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp – a basic circuit used to match the piezo’s signal to levels compatible with modern audio gear inputs. The resulting piezo/preamp combo can be used for electrifying an acoustic guitar or simply exploring the lesser-heard world of small sound around us.
DIY iPhone Remote Automotive Ignition
You’ll someday look back and think of how quaint it was to start your car with a key. With this clever hack, Will O’Brien shows us his working prototype for a remote automotive ignition controlled by an iPhone, an Arduino, and SMS text messaging. Source code and schematics are available on his site.

Collapsable iPhone Camera Handle
Almost every time I attempt to shoot video with a handset I end up inadvertently covering up the microphone or lens, which can be a real drag when I go to view it later on. This has led me to develop a rather cumbersome grip that I use when I film something with my phone. This collapsable iPhone Camera Handle from Chris over at TheNewHobbiest seems like the perfect remedy for this situation
