KeKePad is a plug-and-play platform that replaces conductive thread with tiny connectors and thin cables.
Like most Makers, Michael Yang enjoyed using the Arduino Lilypad for his wearable and e-textile projects. However, he discovered that conductive thread has a few drawbacks: it is expensive, it has no insulation and its resistance is quite high. Plus, in order to achieve a tight connection, the wires need to be soldered (which means that it becomes rather difficult to remove if there are any mistakes).
So, as any DIY spirited individual would do, he set out to solve this problem. The result? KeKePad, a new modular platform that’s 100% compatible with the Arduino LilyPad USB and can be programmed using the Arduino IDE. The board is based on the ATmega32U4 — the same chip that can be found at the heart of the wildly popular Adafruit FLORA — and features built-in USB support, so it can be easily connected to a PC. Like other wearable MCUs, the controller boasts a familiar round shape (which measures 50mm in diameter) along with 12 tiny three-pin Ke Connectors and 11 sew tab pins.
What really sets the platform apart, though, is its unique wiring and connection method. The KeKePad entails a series of small sewable modules that link together via the Ke Connectors and special cables, or Ke Cables, with crimp terminals. This eliminates the frustration often associated with using conductive thread. With a diameter of only 0.32mm, the wire is extremely flexible, super thin and coated in Teflon.
At the moment, there are approximately 20 different modules to choose from, including sensors for detecting light, UV, sound, barometric pressure, temperature, humidity, and acceleration, as well as actuator modules for things such as LEDs, MP3s, OLED displays and vibrating buzzers.
Intrigued? Head over to KeKePad’s Indiegogo campaign, where Yang and his team are currently seeking $2,000. Delivery is slated for April 2016.
