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)

Nice filter for Inst. Amp
Just found this ECG circuit. What was of interest was the filter on the inst. amp’s reference.index.php (PNG Image, 841×468 pixels)
Nothing found that will filter out my mains!
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:

Data prediction equations
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:
More thoughts, keep changing my mind!! - Inked
Still havent had any time to do anything yet but:
Ive decided to run multiple IR modules off one 18F pic then:
I can have a proper multi-master I2C configuration which means proper interrupts.
The IR module will now be smaller/cheaper because of the lack of another pic
Could put some extra fuctions on it too, like voltage/current monitoring [...]
ZBot want to get something working! Inked Thoughts
Decisions:There is no point using some complicated I2C when you can use a simple on/off line. AlthoughWhat 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.
