Future Project Ideas
An Interesting Use of Ultrasound
I have thought of things like this in the past, and it looks like someone has taken the time to actually do it:

I think that they have gone down the wrong road for the mouse part though…
[ I chose not to make the reasons why it is not appropriate and what can be done to [...]
Non Existent Projects?
After months and days of searching I cant find any websites that are developing a hobby based phased array soultion for robots or whatever, so I am very very tempted to get to work on this straight away when I move in, rather than spending time on my robot like I had planned. Also, another [...]
T610 LCD Info
Just for future reference Ive found some sites with a T610 LCD pinout and some code and stuff. Links:

Sound Libraries for Qt
Just been looking around for some open source sound libraries to work in Qt, since Qt has no native support for low(ish) level access.
http://www.libsdl.org/Â - Looks quite complicated
http://www.portaudio.com/trac/wiki/TutorialDir/TutorialStart - Again looks quite complicated
http://www.music.mcgill.ca/~gary/rtaudio/ - Looks the best to me. Object oriented, simple, I’ll try this first.
Facial Recognition and NFX Software
I would like to have a play with facial recognition algorithms, so I had a quick sgeggy on the net to see what I could find. I found quite a few:
Face Recognition Workshop 1 and 2
Eigeface tutorial in Matlab
Face Detection in c# (CodeProject)
Motion Detection in c# (CodeProject)
Video Survelliance in c# (CodeProject)
Would be great if I [...]
Full wave rectification
Just looking into some full wave rectification without diodes and I have so far found 2 ways. One with 2 op amps, quite costly, or one promising one with just a transistor:
I do like the look of this, might be right up my street. It does look slightly jubious, but its worth a [...]
Update: Interactive Light Idea
I found this that is essentially what I thought of the other day, bastards, always knick my ideas (One must admit that they had the idea months ago :D). I personally think that mine would be better though, because it looks like they are using modulated IR face up to detect when someone goes [...]
Quick thoughts on the Ultrasonic Phased Array Project
Just been doing some bored research again, and I came accross this image:
This would be a good route to investigate when I do get it up and running. I Could initially scan for objects, then focus in using this technique. First seen here but there must be other sources out there. Hence, [...]
Few more ideas
Once I’ve finished with the current robot, I would love to get into some sort of UAV design, something like the 4 rotor Helicopter designs ive seen on the internet (see bottom for references).
I’d also like to continue building the EFPD. Possibly place it on a robot that would run away when someoe got close. [...]
