Nick, This is a great idea for a discussion group. Thanks for creating it. I'm having issues with a GPS receiver, so I'll post my plea for help soon. chris...
Nick, very good idea for a group. I'm also involved in acoustics, day job and serious hobby. For fun I'm doing an acoustical study of snapping shrimp in...
I was looking for a sensor-related forum on the web, and I couldn't find one. So, I've decided to start this group. Since sensors are multidisciplinary...
GPS is, probably, the sensor that I've studied the most with. I've worked for the GPS lab at Stanford. Right now I work for one of the GPS startups. I've...
Well, as there seems to be quite a few members registered, and noone is talking, maybe someone would like to chime in on this one. I've got an existing panel...
Here's a great "touch sensor demo" http://ted.com/tedtalks/tedtalksplayer.cfm?key=j_han <http://ted.com/tedtalks/tedtalksplayer.cfm?key=j_han&flashEnabled=1> ...
Looked up the IP67 on Google and found that it means 2 things: - Totally protected against dust - Protected against the effect of immersion between 15cm and 1m...
Thanks for your input Nick, ... Industrial ... In this particular application, it won't work, but it's an interesting idea nonetheless.. I'll have to remember...
I ran accross this a couple of days ago. I don't know what it would take to make a working one. It's an LED touch panel. The video is kink of big. I have no...
... Very interesting. I wonder if the LEDs are switched between emitting and sensing, using neighbors as sources when sensing. The startup shows a row scan,...
Yes, that's how they are doing it. http://motestruments.com/led-touch-sensor-circuit/ I just threw it out because it's different. I don't know if it would work...
The LEDs reminded me that I have an optical flow meter here somewhere; the sensor is a paddle wheel in liquid flow that interrupts an optical path between the...
May be, each pixel has a pair of LEDs with a common lens. Like the 2-color LEDs. There might be a more brute-force approach to a reflective optical touch...
... would work? That's the path I've been experimenting with recently. Emmitter on one side, receiver on the other. I've casted some small prisms from ...
Wow! That's a neat pressure sensor! Although, it's kinda unfortunate that there's no breakout board for the I2C version. May be this article will help you get...
FYI, I just started a forum to help Micromega support their uM-FPU math coprocessors that I want to use. Selfishly, I want others to work with these things,...
Hi, I do a lot of commercial marine robotics and sensors. I am looking for a better way for a robotic vehicle to track its position when its wheels are...
One thing you might consider, is to use the snesors from one of the new laser mice--they are designed to be able to work at a faster rate, and from what I have...
... over a longer distance... Perhaps, but focus is critical and the depth-of-field of the HP lens that is supplied with the sensor is very narrow (+/-0.2mm). ...
... I have quartz halogen lights for video on the vehicle. I just have to get the grazing angle right for the tracker. Do the laser chips need laser light to...
I have the uM-FPU V3 running on a BX-24p via fast SPI. Cam Thompson (of Micromega) has been very generous with his time helping me get a fundamental...
... That is all handled internal to the sensor chip. It has some sort of specialized DSP core so the chip outputs X and Y displacements as well as a light...
With an optical sensor, do you have to make sure that your rover doesn't lift the silt from the bottom? Alternatively (and obviously) you could use non-driven...
... With free swimming underwater robotic vehicles there is something called "dustout" when you kick up seidment which blinds the cameras, and therefore...
Doug, What part of the world are you in? I'm located in CA near Sacramento and have a Seabotix LBV150. I have some future plans that may call for a positioning...
... Doug, I am on Cape Cod Mass. Imetrix, the company I worked for when we designed the Lampray went bankrupt about three years ago. Now two Lamprays exist,...
