Project Voxel are displaying a prototype device at ARM's TechCon event in Santa Clara from the 1st - 3rd October. The device is a demonstration of using the Nordic nRF51822 as a mbed target, specifically an mbed target that is capable of controlling Bluetooth Low Energy connections.
The current device includes:
- NXP LPC11U35 - as the mbed interface
- Nordic Semiconductor nRF51822 - as the mbed target and BLE interface
- Dual full RGB LEDs - to allow for bright and customisable notification
- Dual power supplies (either USB or rechargeable battery) along with USB charging support for the battery
The list of sensors that we are currently looking to support in our hardware design include:
- Light level
- Temperature & humidity
We are also looking into the possibility of developing a wearable device using the same basis technologies from the larger development board. This wearable will be targeted at event and gig settings where the crowd can become a giant lighting system. Unlike a few other technologies that currently exist within the market, we will be specifically looking to create a reusable device that can interact with other people's devices and its surroundings. We will be posting much more information about this project on our blog.
Our team consists of three, third-year engineers studying at the University of Cambridge. We have received both financial and technical support in our project from both ARM and SPIP (a project sponsorship system setup by the Engineering Department), and through this project we aim to help others learn the basics of surface mount circuit design and soldering. Before we started this project, our team only had a very small experience of circuit design and had never worked with surface mount components - so we really appreciate the assistance we have received.
