Al Jazeera’s Investigative Unit enters the secretive world of the surveillance industry. Interesting documentary on some of the shady deals that go on behind closed doors. Watch this (about 48 mins) and draw your own conclusions. A good enough reason to look at using encryption etc, not to stop governments, but to stop…

Raspberry Pi and RealVNC
You can now remotely connect to your Raspberry pi with RealVNC. There are more details on the Raspberry Pi website blog post. After a little bit of experimentation. I have got this working, still needs a few tweaks, but I have now enabled the option to allow Minecraft pi to be displayed inside…

My latest arduino project is based on the IR sensor Tom is using as part of his IR robot project. However I don’t want to go down the same route of building a robot that just follows an IR LED around. Bottom is a IR led and a switch connected to a CR2023 cell…

The November issue of Linux voice (soon to be integrated with Linux Magazine) had a tutorial on creating a simple IRC bot. (ircbot1.py) I have been experimenting with this and have put the code on github various irc chat botshttps://github.com/zleap/irc_bots1 forks.0 open issues.Recent commits: add comments re webcam, paul Sutton Merge branch 'master' of…

I seem to have been busy with a few things over the last few days. Firstly as my Arduino clock has failed (basically the time needs re-setting ). I decided to therefore use the breadboard for something else. I also need the LCD display for another project. I found instructions for a HC-SR04 triggered alarm…

Further to my previous post on this. Pin headers are now soldered on to the motor board, and the project is rebuilt. This works much better. A bit of re-wiring was needed but it is complete and does find objects and turns to avoid them. The code probably needs a little more refining. I…

Busy(ish) day today. I have now fixed my robot, Initially I powered the motor shield and Arduino from 2 separate 6v Supplies, then after talking to Tom on IRC looked closely and some of the pins were out of alignments so the power was not getting from Arduino to the motor shield,. I fixed that…

I have recently replaced my broken Arduino UNO R3 with a new one. I am now experimenting with a HC5883L 3 axis magnetic compass module. Details here With the official page here. (recommended) You will also need to download libraries.rar from http://www.ardumotive.com/digital-compass.html and extract it in to your libraries folder, then restart the Arduino IDE….

Today I soldered up the LED mood light I build and blogged about in Part 23 of this series. However I made a few changes to this Soldered 2 x Tri-Colour LEDs connected a 15 pin header to the top, as I have done with other projects and a 3 pin header for ground. I…
