Node red

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.

Head of to http://nodered.org if you have yet see this.

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.

PCB design

Fritzing is a useful PCB design editor and on their site (http://fritzing.org) you can as well find a lot designs shared by others.
I haven’t yet tried the Fritzing fab, to turn you design into a real pcb, but will put it on my wish list.

Väggarna monterade

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.

Inför montering av väggar

Nu är det förberedelser inför monteringen. Jag tar ut samtliga element och ställer ut dom på prov. Bestämmer mig även var jag skall starta och gör lite extra mätningar.
