Project ideas…
- US range finder for ZBot
- US Phased Array
- 2d/3d phased array
- 2d phased array without beamforming
- stereo phased array? (2 tx’s, many recieves)
- Brainwave analyser to monitor my many moods!
My Blog, with Stuff on.
Just found this ECG circuit. What was of interest was the filter on the inst. amp’s reference.

Had a look round to try and find a front end filter that wont trash the input impedance. Cant find much, but I posted a few posts on forums, so we shall see what turns up there:

According to Feynmens lectures on physics (pp. 8-12), the electrostatic equations are not valid for close proximity electrtostatic forces. This leaves the equation field wide open to essentially use what I want. Playing with Excel found that the best (where simple) equation to use was 1/(1+2.7*(x^3)).
The graphed output of this equation looks like:
Still havent had any time to do anything yet but:
Ive decided to run multiple IR modules off one 18F pic then:
This does still mean that the I2C routines will have to be written (boaring!) since that was what my motivation was dreading before.
Also still love the idea of creating a phased array sonar system on it, but that will come later…
Could look for some code on the net, see if that will help/save a lot of time. Just depends how its been written…

Decisions:
There is no point using some complicated I2C when you can use a simple on/off line. Although
What about inter-IR communications?
And it should be independent and modular?
I think that I am going to bypass the I2C for now. Use the I2C bus as an On/Off for ALL Ir sensors to get things up and running.
