Focus a beam of sound at objects or into your head!
The Soundlazer directional audio project is the continuation of my first and very successful project here on Kickstarter. I developed the Soundlazer “Snap” during my quest to lower the cost of this amazing technology and give backers the opportunity to explore new possibilities in directional audio.
Parametric speakers like the Soundlazer are directional speaker systems. They use ultrasonic carrier waves to transmit audio to listeners in a focused beam of sound that acts like light from a laser. Generally speaking, only the person standing in front of a parametric speaker can hear the audio being transmitted. People to the sides of the directional audio source hear little or no sound.

If Arduino is your development platform of choice the tiny self-contained MicroLink board offers some interesting features. At just 50 x 32 mm it contains an ATmega328, an SIM800H quad band GSM module and on-board USB and battery charging capabilities. It has all the peripherals necessary to allow wireless remote control and monitoring and can use any standard 3.7 V LiPo battery for power which is charged when the USB port is connected. The charge state can be checked at any time from a remote location.

Ever been looking for your keys, and wanted to call them, before you realize that they are hideously analog pieces of metal? Or wanted to let someone into your house when you’re not at home, without having to lend them your keys?
Lockitron was the solution that descended from hardware heaven – a device that fits over the lock on your door and that is controlled via an app. It raised $2.2M on Kickstarter but missed its original shipping deadline by 1.5 years, leaving its backers in a deadlock (pun!). Are you one of them? Stop glaring at your empty mailbox and channel all your frustration into making your own awesome smartphone connected lock – The Bean Lock.

Open Analog is an organization dedicated to exciting makers about analog hardware. We make popular ICs into transistor level kits!
The first Open Source analog IC kit from Open Analog has been created, assembled, and verified. We call it the SevenFortyFun and it is a transistor level op amp kit. You can finally get the chance to understand whats going on inside those ICs! Now we need your help to proto the next revision (I gotta eat somehow!). This Kickstarter campaign is to raise money in order to print the first batch of PCBs and order parts for production volume.

When you think Raspberry Pi and camera you probably already know the score; a small camera board that plugs into the Pi’s CSI connector fitted with a fixed-focus wide-angle lens. This versatile setup has been the basis of all sorts of homebrew applications. The SnapPiCam takes the Pi down a different route and converts it into a 5 MP digital camera with interchangeable lens.
Gregory L Holloway is the brains behind this idea, he developed it as an entry into an Instructables competition (which he won) and the response he got encouraged him to launch it on Kickstarter. The design uses the lower spec RPi A without an Ethernet port and with 256 MB of RAM. The camera includes a LiPo battery and DC-DC converter to make it truly portable and different versions allow you to add a rear touchscreen and various interchangeable, magnetic-mount lens ranging from wide-angle to telephoto zoom.
