Well, generally when a deadline is approaching I tend to lose focus from work :D . Well having one close deadline, today I remember to refresh my BlitzMax knowledge! BlitzMax is a 2D game development environment that I bought some years ago. If you are interested on 2D game programming you should check it out. When I was doing my research, I found it to be at the exact abstract level that I needed it to be, hiding enough details from the ‘boring stuff’ and at the same time having great flexibility.

I read this today and I think it is pretty interesting.

Schneider Electric company have developed a new prototype switch for ZigBee networks that operates completely green! That means no batteries at all! This self-powered switch could be real useful in housing applications. Convenient, wireless and total green. What else could you ask for?

See more info here. It’s their press release.

Need motors for your robot? – Servo Motor Hack

Another quick post. If you are just starting on small scale robots you may wondering what motors to use for movement. A quick google search may scare you actually :)

I am telling you this because I had a similar experience when I was starting out. You see, if you look for ‘robot motors’ you are most probably be taken to a DC motors website. First of all a decent DC motor would probably cost more than a newcomer wants to spend just to test it out. And most important it is quite complicated as you need to mess around with DC motor controllers and other stuff like gearing. Read more…

Zigbee Networks – PIC Xbee project

Hello again,
Long time no see huh! Well I was pretty busy with many many things. I hope I can find more time to write more posts here. Today we are going to talk about PIC Zigbee projects.

Last year I was working on a PIC project that needed wireless communication and I made a little research on the internet where I came across ZigBee networks. Zigbee specification is ideal for low power applications. It is actually an offspring of the IEEE 802.15.4-2003 standard which is aiming low power wireless communications. Read more…

The 1-wire (o/w) Protocol – DS18S20

Hello again,

This post is actually going to become handy on the future posts I am planning for the DS18S20 thermometer. This is a well known and used thermometer as it simple to implement and quite accurate. I will do a brief description of the protocol it uses to communicate with our PIC. Through this protocol we can send commands to the DS18S20 and receive data and responses.
This is actually a brief review of the datasheet of the device which is already very simple to understand. This post is just to introduce the basics of the o/w protocol.

First you can download the latest pdf from here. Read more…

How high is too high?

Hello boys and girls.

A common question I come across quite often, is from a where a beginner should start his/her microcontroller programming adventure. I remember myself wondering exactly the same thing when I was starting out, not too long ago. So which is the best to program? Assembly or C or Basic or… ?

Well I am going to give you my opinion and how well it worked for me. Let’s face it, knowing what is going under the hood is the best experience anyone can get working on any kind of project. If you know exactly how the system works, then you will be able to squeeze every last drop of juice the microcontroller has to offer. Read more…

Hey! This is the first post of my blog. I am going to keep it a simple and hope that is going to grow larger and stronger!

So here goes the first post!
