Thank You to everyone for the PID info. I ended up using Bruce's suggestion: learn directly from Alex! Alex gave us a tutorial on how he implements PID control...
Hi, first time poster; has anybody here ever worked with a capaciflector (proximity detector device based on using capacitance to sense distance)? It seems the...
This is a very interesting idea! A quick Google search turns up a number of relevant references. However, the range seems to be quite limited - apparently...
Happy New Year SDIEEE-RAS Members and Friends ! Please join us for a great kickoff meeting for 2005 ! An announcement for our first meeting of the year is...

I am preparing three vehicles for the DARPA Grand Challenge Field Test and need your help. Can you help me gather the Manpower, Materials and Money needed to...
... capaciflector (proximity detector device based on using capacitance to sense distance)? It seems the concept has been out there for a while but it does not...
To add to Gordon's comment about different capacitances, when Jim Ubersetzig brought his theremin in to the RSSC meeting, we did some rough testing to see...
Alex and Gordon, thank you for your replies and observations regarding the use of capaciflectors...maybe i should play a little with a sample to get a feel for...
... For a DIY robotics club, I do not think SD is that big on volunteer projects. Earle __________________________________ Do you Yahoo!? Yahoo! Mail - Find...
Unfortunately my schedule prevented me from attending the last few meetings, it’s about that time of year when we elect our club officers. Has this happened...
Hi Jerry : Thanks for your help with the website: Yes we held an election yesterday. By Unanimous vote: Russell Newman was elected President. Bill Douglas was...

Hi All, I've been teaching Leaf to detect faces. The good news on this is that the same software should be able to detect things other than faces, possibly...
Hi Robin, Looks pretty good. I've downloaded three more samples to the file under "Alex samples". A little darker background (and foreground for that ...
Thanks Alex! One thing, though, it seems the photos didn't get stored. At least, I'm not finding anything new under photos>faces. Would you mind posting them...
Thanks Bruce! Bruce1.jpg is the most useful. It's something an indoor robot might see and which we'd expect it to recognize as a face. - Robin ... you. And...
... capaciflectors...maybe i should play a little with a sample to get a feel for it. Think "sensor fusion." As long as the sensors aren't topo expensive or...
In my consulting work for Technicolor I've had to learn a lot about DirectShow and other media technologies. For those unfamiliar with the term, DirectShow is...
Hi Gordon, That would be cool. I use DirectShow for frame capture in Leaf, and it works very well -- fast and low cpu overhead. Anything you come up with ...
Hi all I have a 12 volt lead acid battery and a 5V 10 a DC-DC supply from Jameco. However, I found that some of my electronics needed 7.5 volts. I did not...
I'll second that! Anything that can be added or integrated into Leaf's existing capabilities is more than welcome!! And I can immediately see the "motion...
Gordon McComb wrote a great article in January's Servo magazine on searching the internet. Here's my challenge: There are researchers out there writing...
Very easy. Just use a 7805 voltage regulator. While not overly efficient it is probably your best bet. Anyway the trick is to raise the ground level that the...
Hi, Actually, the Sharp IRs generate some large current pulses when they fire their LEDs which can cause spikes on the power supply. See my website at...
You could do this but it would be waist full, take a look at this part, very simple to implement and it’s a switching regulator, you can adjust it to any...
