How software can solve hardware problems

I’ve developed my own sprinkler system and my own humidity sensor. This sensor is extremely simple as you can read in my article. The main problem of this sensor is that the data to be read is an analogic data and the length of the cable is very long. There are lots of problems implied…

A soil low cost humidity sensor (moisture) and .NET Micro Framework (NETMF)

I’m working on my own sprinkler system which I can pilot thru Internet wherever I am. I can add programs and also open and close sprinklers when I want. I recently build a prototype of a humidity sensor. Now it’s time to implement this humidity sensor in pre production and see how it is working…

A low cost humidity sensor for my sprinkler system

I’ve developed my own sprinkler system which embed a web server and allow me to control it remotely where ever I am. I can program when and how long I will sprinkler on which circuit. I have 3 circuits but my system can work with a large number of circuits. What I want to do…

Using XMLHttpRequest to pilot a Lego train dynamically in HTML 5

It’s a long time I did not write a blog post. I was very busy and had no time to write and code anything in the last weeks. I still have a lot of work but I need an intellectual break for the evening. So I do not write this post from a plane but…

Creating an efficient HTTP Web Server for .NET Microframework (NETMF)

That’s not the first post I’m doing on incorporating a Web Server in .NET Microframework (NETMF). In some of my previous posts, I’ve explain how to do it using the existing .NET classes for this. And it is working very well! The main concerns I have is that I’m using a netduino board. This board…

Using a SPI device with netduino and .NET micro framework

After playing with I2C, with various IO, I’ve decided to play a bit with SPI The real project behind using a SPI device is to be able to use it a a multiplexer/demultipler of IO. I want to pilot lights for my Lego train. The idea is to have the ability to switch a signal…

Managing my Sprinklers from the Cloud

I’ve started a project to pilot my sprinklers remotely and make them smart almost 9 months ago. The idea is to be able to remotely open and close my sprinklers but also be able to launch automatic sprinkling cycles. After some software and hardware development, I now have a fully working solution: You can see…

Using netduino and .NET Microframework to pilot any Lego Power Function thru Infrared (part 2)

In a previous post, I’ve started to describe the Lego Power Function protocol and how I’ve implemented it on a netduino board using .NET Microframework. My work is based on ideas and implementation Mario explain in his blog. We’ve exchange couple of emails to make both our projects work To continue where I stopped, The…
