Z-wave and python node discovery, more bitwise trickery

This post continues upon the last blog post, in the last post we looked at some z-wave protocol basics. At the same time we had a look at a bitwise operation (XOR), in this post some more bitwise tricks will be used to do z-wave node discovery. Node discovery is essential to get information about […]

Getting started with z-wave and python

I started playing around with my new z-wave kit. I ordered an Aeon-Labs Z-stick (series 2) and a Duwi dimmer module to start with. Here are some images of both devices:

Jeenode infrared project part 5: extending IR range

Ok, so my IR controller has been running for a while. Though I was only using it for receiving for now. The range of the IR LED was not sufficient enough to control my devices. Today I had a look into the hardware schematics. I increased the transmitting power by using a NPN transistor (BC549).

Jeenode infrared project part 4: a better home…

Agreed, a breadboard looks nice and “hacky”. But, it doesn’t really fit nicely into my interior :-) It’s time to give the Jeenode infrared sender/receiver a better home! The main ingredients to get this going are: Hot glue (love that stuff) Solder Some wires A Jeelabs carrier board with case A drill A lot of […]

Jeenode infrared project part 3: sending test

In the first and second part of this series I introduced my idea’s about the IR project.I also showed some basic receiving, and even receiving over the air.What was left out, was the sending part. Today I found some time to get a sending setup together.

Green Jeenode

I have just powered my first Jeenode with solar power.This node has been running for 5 days now. The solar panel is one normally used to charge cell phones.It supplies 5v and has a accu pack of 2800mah, this should keep this node running for quite a while…Click on “More” for a image of this […]

Jeenode infrared project part 2: going wireless

In part 1 of this series I blogged about receiving infrared signals using an IR led. This blog post will focus on getting the signals up in the air (and off course receiving them on the other side, in my case my home automation server with a Jeelink attached) The Jeenode’s have a HopeRF wireless […]

Jeenode infrared project part 1: getting started

Today I received new Jeenodes, so it’s time for more electronics fun :-) One thing that I head in my head for a while was an infrared receiver and sender. I want it to be like an advanced Logitech Harmony, the main downside on the Logitech Harmony is that there is no status tracking. What […]

Automating/reading sensorbin status using JeeNode/Arduino

I’m currently playing around with Jeenode boards. The JeeNode is a small wireless board with an 8-bit Atmel RISC microprocessor. JeeNodes are compatible with the Arduino platform and can be programmed under Windows, Mac OS X, or Linux using sketches created with the Arduino IDE. As a first test of it’s capabilities, I wanted to […]
