Arduino-compatible Rox1 shield - Interface any current Centeye chip to an Arduino.

I like Arduinos. They are inexpensive, open source, and insanely easy to program. The Arduino environment also comes with a nice little serial monitor making it easy to monitor what a program is doing and "debug" if necessary. So in the past we decided to hook up an Arduino Pro Mini to a FireflySmall sensor, to make an optical flow sensor. This worked, and we received a…

Turn your Arduino into an blazing image processing machine! (Tam2 and Tam4 chip shields available at Centeye)

(Left: Arduino Duemilanove with Rox1 shield and Tam4 chip, Middle: Arduino Pro Mini with Rox1 shield and Tam4 chip, Right: U.S. Quarter for size comparison)

Well this might be a slight exaggeration- As neat as they are, an Arduino isn't exactly a supercomputer. But we did manage to use an Arduino to grab imagery and process optical…

XMOS board update

 

I got the PCB's today, and cut some out with a table saw. They came out great, and I started populating it. Right now I am having trouble with the voltage regulator actually regulating to 1v vs. to some other random voltage (.2v, and .6v so far). I suspect I have the LC matching wrong, as the datasheet calls for 10uf with a 2.2uh inductor, but I have 200nf at the moment. I will try to get the whole board…

Open Source Hardware (OSHW) Definition, version 1.0, has been released!

On the 23rd of September, early in the morning, I took a taxi from my home to National Airport (DCA) here in DC, and boarded a flight to Laguardia Airport (LGA). The airplane went up, then went down, and a short while later I was in a taxi, trying to find this "New York Hall of Science". The cab driver had no idea where it was, but with GPS we managed to find it. I met up with Alison, who lives in Brooklyn (she biked over; I had to fly) and we entered the Hall of Science to attend an event I…

Introducing the new CYE32 open source sensors

Hello Everyone,

Below I've posted layouts of the new CYE32 open source sensors, based around the Atmel at32uc3b1256 32-bit microcontroller.  The CYE32 line offers a significant performance increase over the CYE8 line of sensors, features an external 12-bit ADC, and uses the same microcontroller that we are using in the vision-based hover-in-place demos…
