Just entered a project for the hackster.io The Future of Smart Homes and Offices contest and applied for one of the MediaTek LinkIt™ Smart 7688 Duo HDK development boards they are giving away for the top 100 project ideas. Fingers crossed!

The Smart 7688 Duo is compatible with the Arduino Yún and features:

  • 580 MHz MIPS CPU
  • Single input single output(1T1R) Wi-Fi 802.11 b/g/n (2.4G)
  • Pin-out for GPIO, I2C, SPI, SPIS, UART, PWM and Ethernet Port
  • 32MB Flash and 128MB DDR2 RAM
  • USB host
  • Micro SD slot
  • Support for Arduino (ATmega32U4)

The LinkIt Smart 7688 Duo runs the popular open source OpenWrt operating system (often used on wireless routers), on the MT7688AN SOC. That powerful base means that you can build device applications for the LinkIt Smart 7688 Duo in several different languages, including Python, Node.JS, and C.

My project is a slack bot (written in Node.js) for each room in a venue, monitoring the environment (temp, humidity) and occupancy (PIR). One Smart 7688 Duo for each room, connected to slack and providing a simple web app for meeting rooms, etc that can be displayed on a tablet outside the room. The bots for meeting rooms have a room calendar so each room knows when it should be occupied and can detect no-shows.

Other possible sensor options include monitoring the power consumption of key equipment, for those times when you forget to turn off solder stations at the end of the day… Controlling smart lighting (WiFi, ZigBee, etc). A camera to remind the room booker when they forget to clear away coffee mugs, etc. Not running the AC when the windows are open…
