I’ve been doing some pretty heavy reading and writing for the last few days, so I took some time “off” this afternoon to work on a mini project that I had been thinking of for awhile. I wanted to write

Current Sensing with the ACS712 Hall Effect Sensor
After a conversation with JD Warren, one of authors of the excellent Arduino Robotics book, I decided to try the ACS712 hall effect current sensor. I soldered one to a surface mount to breadboard adapters and plugged it in with
Continue readingDigital signal processing and filtering – motor current sensing
After a recent post on current sensing, I talked to a couple of friends at NYC Resistor (my usual sounding board) and got some great advice (as usual). One thing I didn’t remember was the difference between passive and active

In my last post, I talked about using an RC filter to get rid of some of the noise in the current signal I was getting from the Arduino. While this worked okay, I still wasn’t super happy with the

I have been working with Greg Borenstien for a while now on creating an open source tool for visualizing human movement data. You can see all his code here on github. We needed some data that had x, y, and

Greg, a former student of mine and current friend/colleague/author/resident researcher at NYU ITP put together this animation within hours of meeting with him to talk about the human movement visualization work needed in the Applied Dynamics & Optimization Lab at
