"got our thermal sensor (omron 16 pixel) and run the test arduino and processing program. Looks as thou it's gonna work overlaying with the stonyman chip as a dynamic reference and the omron as the absolute reference.

First of all, thanks for a very interesting site and product.
Second, how soon to you think the Aphid's will be on the street?
And third, after reading your comment about hooking the project up to a low power micro controller, I…"

I have a question to the Stonyman data sheet “10.5 Binning and reading a binned e.g. downsampled image (STONYMAN ONLY)”:If I use 4x4 blocks then the Stonyman chip is bin down to 28x28 and not 23x23?I refer to the „ArduEyeSMHClass“, Function setBinning:Why is for example (if I want to downsample by 4) hsw=0xEE and not hsw=0x77?Thanks for helping.MichaelSee More

Richard replied to Geoffrey L. Barrows's discussion Use of Stonyman chips with an Arduino Due (or other 3.3V ARM)"I just made a quick attempt to compile FirstApp on the Arduino Due. I connected the stonyman breakout board to the normal pins on the board as indicated by Geof:

D8 = RESP
A0 = ANALOG

Internet of Things (IoT) car traffic counter camera using an ArduEye and COSM
Eager to make a little foray into the "Internet of Things", I decided to experiment with the use of an ArduEye as an "Eye for the IoT". My house is on a fairly busy street, of which I have a good vantage point from my attic home office. A car traffic counter seemed like a good choice…

eye tracking experiment
Due to my need to develop some form of eyegaze mouse we have been (wife & I) using ardueye as an embedded first stage. Here is where we have got so far.
1) Hooked up camera at close to correct focal lenght to eye
2) Established that the eye will track left and right and display in some form that we can use.
3) Worked out the drift in the system focusing on the eyeball (similar to a gyro drift).
We have success in the above three.…

BCIT students make eye tracking computer input device, for ALS patients, using Centeye chip
This is the type of news that makes everything we do worthwhile! This past January, I was contacted by Alex Sayer, Alan Kwok, and Benny Chick, students at the British Columbia Institute of Technology (BCIT) in Vancouver, who wanted to use some of our Tam2 chips for a class project in which they would provide a human-computer interface (HCI) for people suffering from ALS (Lou Gehrig's disease) and could not operate a computer using their hands. Their idea: Use a low resolution image sensor,…

What can you do with an ArduEye?
We've had a lot of inquiries about our ArduEye system, plus we've just prototyped a smaller, completely self-contained ArduEye (more on this in another post). So I figure it makes sense to discuss what is actually possible with one of these devices. True, the ATmega328 processing engine of an Arduino is limited compared to more advanced DSP, but the reality is that for many applications you really don't need a whole lot of pixels. If you can get by with specs of the '328 (16MHz as an…

Low Cost Embedded Vision Module
Hello,
I recently stumbled upon this community and my current project is a perfect match. I am working on a low cost vision module, in the opposite end of the spectrum from CentEye.
Currently there are not many good options if you want a low cost vision module. CMUCam4 looks…
