Greetings. Walter Martinez brought a Lego robot to one of the RSSC workshops a few months back, and demonstrated some NQC (Not Quite C) programs on it. I...

1-4pm, Saturday, Feb. 7th Hopefully we will have more than one competitor for the bump-n-go contest. Bring whatever you're working on. For directions: ...
SDRS Monthly Meeting minutes. Meeting held on February 7th, 2004. We had four new people show up, which is always good. Us regulars get to show off our robots...
Hi! I just read an article that said: "802.11g merged two incompatible wireless networking standards--802.11b (goes far but not fast) and 802.11a (goes fast...
Hi Bruce ! welcome back , glad to hear you're online again Briefly the 802.11x standards are a wireless ethernet or Local area network standard and are based...

Hi Steve! And thanks for the overview - this wireless stuff is all still new to me... but at least now I understand it a little better!! Bruce. ... From: steve...
I'm researching both and it looks like both detect tilt, what's the difference? This was probably explained during a club session but the research has got me...
During my demonstration at last months RSSC meeting I touched briefly on the hardware that I intend to construct for use with the Cerebellum compiler. The...
Hi, Acceleration is proportional to tilt IF the accelerometer is staying in one place and not actually accelerating along its sensitive axis. For example, if...
Hi Bruce, I wrote a detailed analysis of various wireless standards for my small robotics projects a while back. It should give you a decent overview of the...
... An accelerometer is sensitive to gravity, so if you mount it with the axis horizontal, you can use it to measure tilt. A gyroscope is typically sensitive...
The 2nd Mini-Sumo tournament will be held this Saturday at the RSSC meeting. The contest will begin at 12:00. There is a small prize for the winner. I'd like...
Thanks for simplifying it Alex. I'm back on track again. The way manufacturers write their stuff, you'd think the chips also does the dishes. I'm leaning ...
The problem with the ADXL250 is that it reads 50 g's. This means the normal kind of signal we get (+/- 1 g) makes very little change to the analog signal....
Cool, thanks again. ADXL202 it is then. Let me ask, what about RC Helicopter Gyros like the Cirrus MPG-6 or other sub $60 RC rate gyros? Probably a stupid ...
Hi Mike and all: I did a google search for the Accelerometers today and found Analog devices will mail free samples (2) ADxl202E just for filling out a form ...

I haven't used an RC gyro. You'd have to read the pulse width rather than an analog voltage. I think I became convinced that the technology used for their...
This gets sweeter by the hour. Now if they approve my request for the 2 free samples and I can order the PCB, the cash I'll save! I may still order an ...
I guess I'll back off the RC gyros. I'd love to get a rate Gyro for about $30. I guess that just doesn't exist huh? It's not bad spending the $50 for an eval. ...
At this point I have no idea as to the final cost as the specifications are not yet complete. The sooner I get the specs nailed down the sooner we can start...
Hi Robot Fans: This Valentines day , why not spend the afternoon with something that doesn't need you to buy it Valentines or Chocolate ? Come on out to the...
