The CHIP/MQTT Broker features an early CHIP computer module, uses a tri-color LED as a user interface and is wrapped in a decorative Steampunk-inspired ticker-tape glass dome and base. The CHIP has on-board WiFI/Bluetooth, lots of GPIO pins and Linux in flash-memory. It’s set up as a local WiFi access point and runs the Mosquitto MQTT broker. The LED responds to MQTT messages from the network and other WiFi devices through Python programs and regular Linux scripts.
The 5th-generation conference badge sports a 3.5″ color TFT touchscreen and a Raspberry Pi 3, wrapped in a decorative brass and leather Steampunk-themed package. An additional Arduino Pro Mini manages the ultrasonic range finder, with an “ozone tube”, photocell and digital temperature sensors, in the works. The device plays promotional .mp4 movies using mplayer, on the display and runs for about 2 hours on a 2200 Ah cell battery. There were a lot of “Wow, what’s thats?” when I wore it to a recent conference in Santa Clara.
I recently started a brand new column on TheNewStack.io about hardware hacking. The series walks through tips, techniques and projects for the physical computing hardware hacker.
The first edition, Off-The-Shelf-Hacker: The Physical Computing Stack, introduced the reader to the exciting new world of off-the-shelf microcontrollers, sensors, actuators, Linux/Free software, NanoLinux systems and companion topics like the Arduino, Raspberry Pi, ESP8266, and other tools and designs of the DIY (do-it-yourself) and Maker movement.
Future stories will take readers through hands-on fabrication tutorials, using various programming tools/frameworks and discussions on using sensors, micro-controllers, nano-Linux systems and interfacing to various electronic/mechanical devices.
The articles will appear weekly, typically over the weekend.
If you want to get into hacking hardware and building physical computing projects, be sure to check it out.
