Give your gizmo the gift of sight
One question that keeps coming up is whether you can use an Arduino Due with the Stonyman chips, especially since the ARM processor on the Due operates at 3.3V. I don't have a 'Due yet, but we have…Continue

In our experiments with eyeballtracking we did some pc based experiements altering a off the shelf ps3 camera to specific instructions. The stonyman set up for tracking eyeballs turned out to be…Continue
Hi,I have a question regarding the calculation of the mask (I refer to the Stonyman/Hawksbill vision chip library “ArduEye_SMH.h”).The function calcMask finds the minimum (pixel) value of an image…Continue
I finally got a good LED strip to place behind the cameras, 300ma at 3.5volts. Makes a lot of difference in the calibration.
I am just playing with simple-solutions to 3D right now. It really is intriguing trying to figure out a non-moving picture way of getting 3D distances. It is really easy with a single item like a pencil on a plain background. But that's cheating. My attempt at subracting the left and right eye, then showing only the pixels with the same +/-3 of 16 brightness…Continue

SO>>> the LCD screen is 160x128, so some of it is not used. Movie updates are about 8 per second.. only EYE number 1 is shown. The text is my diagnostic readout.
The actual pixels are read using the amplifier on the Stonyman at max gain. The PHI times are 1us high/2.5us low (before A/D). The…Continue

We have updated the Stonyman data sheet to include software exemples (in Pseudocode). Version 1.0 is here: Stonyman_Hawksbill_ChipInstructions_Rev10_20130312.pdf

We have a small batch of ArduEye Aphids that are now available for serious beta users. An Aphid is essentially a clone of an Arduino Pro Mini but with a Stonyman vision chip and an external 12-bit 100ksps ADC added. For more details and for ordering, please visit the…Continue

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…Continue
Track, store & drive two motors in x & y plane untill the real time image on vision chip is tightly aligned with preset neutrl position. Can anyone help me build this unit?
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.…Continue
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,…Continue

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…Continue

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…Continue
