FlipKey:   Compact Key Organizer

Organize Your Pocket!

FlipKey is a new, affordable way to carry keys and other accessories without the annoying problems associated with the classic keychain. If you use a keychain, this product is for you.


The solution is a design that combines simplicity and function. FlipKey uses a bolt to keep everything in place, and small metal washers to prevent the keys from sticking together. It is compatible with almost all commonly used keys, plus many more. Uniquely sized keys will still work too, because FlipKey can come in any variation. Just measure the width and length of your keys, and we will do the work for you. In addition to keys, FlipKey accommodates other small accessories like USB drives, bottle openers, or screwdrivers. 

FlipKey feels good in your pocket. It won’t jingle or poke you in the leg. It’s cheap, it works, and it’s built to last. 

Modernize your life, and change the way you store, find, and use your keys. 

Soundbox Mini

The Soundbox Mini is a simple audio synthesizer targeted toward individuals who are interested in electronic music production and looking to get a start in electronics.


When purchased, the Soundbox Mini comes in a kit format and must be assembled by the user. In doing so, users will learn the basics of electronic circuit design. The kit includes: an Arduino Uno, a small speaker, five potentiometers, a simple switch, and a ribbon controller. It also includes a plastic enclosure to house the electronics, an aluminium panel to mount the controls and speaker, and an acrylic faceplate (Figure 1). Users can customize the face of the device by downloading the faceplate template from the Soundbox website (Figure 2). Using the template, the user can create a custom design for the device, for example an image of space (Figure 3). The sounds produced by the Soundbox Mini can also be customized using the downloadable software interface. The Soundbox Mini is powered by a standard DC adapter (Figure 5) and the sound is produced by a built-in speaker.


The Soundbox Mini features a power switch and five control knobs (Figure 4). There is also a ribbon controller along the bottom of the device. The ribbon can be thought of like a miniature keyboard. The user plays the Soundbox Mini by applying pressure to the ribbon to produce varying pitches. The two control knobs along the top are volume and rate. The volume knob is self-explanatory while the rate knob controls the rate at which sounds are produced when the user applies steady pressure to the ribbon controller. At the slowest setting, sound is produced at one tone every five seconds. When turned up to the fastest setting, the tone produced is constant. The LED above the rate knob flashes at the current rate, providing a visual indication of the current rate setting. The three knobs along the bottom control various aspects of the sound. By experimenting with different positions of the knobs, the user can produce an infinite number of sounds.


Since the Soundbox Mini is powered by an Arduino, advanced users have the ability to re-program the synthesizer to produce their own unique sounds by connecting it to a computer via USB (Figure 5). The controls can also be re-programmed to change the effects offered by the Soundbox Mini.
