This is a hobby project by Martin Harizanov. A small Arduiono with usb and radio module.
This is v3 of my “Funky” Arduino clone, specifically designed to be small, with on-board radio module and for low power applications.
- Board size is 20×21.2mm (0.78″x0.83″)
- Weighs 3 grams (0.11 oz)
- Compatible with Arduino IDE
- ATMega32U4 MCU, the same as processor used in the popular Arduino Leonardo
- No need for external programmer to upload new sketch – just use micro USB cable
- Equipped with 433/868 wireless RFM12B or RFM69CW transceiver module
- Runs on 8 Mhz and can be powered from 2.7-3.3V power source, including coin cell battery
- Low power operating mode

IBM is very active in both open source as well as in IoT. Here is a very nice tool for anyone into integration of any sorts of data flow.
I have it installed on one of my Raspberry Pi’s and it allow me to visually create integration mixing hardware and software.

Update, 25 Jan 2016: Node Red is included in the Jessie build for Raspberry pi. After struggling to get the GPIO to work with my old build, I decided to start from scratch. It was worth it. Node red is now only a menu option away, works like a sharm.
Extra benefit: The new GUI in Jessie (if you don’t decide for the slim down version) is very nice.
One example of what I included as my first experiment:
I have motion running with a camera overlooking my garden and street. As soon motion is detected it sends an event to a MQTT broker I’m running on another Pi. Then I have a node flow that subscribes to that topic and makes a http against my Sonos system to play a short notification indicating ‘car is arriving’. The Sonos api is based on node (min version 4) by jishi.
Förra helgen var det isbeläggning i botten men idag bättre lämpat väder. Ca 9 grader och lite dugg regn.
Alla väggelement är nu fastsatta med fogskum (Sika Boom S All season). Skönt att ha passerat detta momentet. Jag kommer täcka alla pelarhål för att inte få dom vattenfyllda inför nästa moment som är att gjuta pelarna.
Here is a nice Tork EasyCube enabled dispenser
