I would disagree with everyone who thinks PIC discussions doesn't belong to this group either. I think we're beyond the times where you could do everything with discrete components. These days

Yeah, solar...wind...geothermal. But what does this have to do with electronics? I suggest an alternative energy group/website. _________________________________________________________________ Get

You'd get a better answer on the PIC group.

I agree.... I am not a fan of proprietary hardware or software for that matter

aconite, Yes, both were startup companies, HP in the thirties and I think Compaq in the seventies. Both had a good rep at one time. Right now those HP boxes are the ugliest things I have ever seen. A

I read an article where compac and hp are merging...crazy

Daniel, If that is the case I doubt that they are using very old computers. And it would seem wiser to dump everything but the system board. A few larger power supplies are better than many small

manifold, Yes, just design a system with multiple (not just dual) CPUs. Of course the system to manage the programs among all those chips is still going to be a bear to design. Jim

hey , try and read RS485...that will help you have digital signal speed of about 2Mbps... and believe me Digital is easy and better when it comes to working with signals and you can control them

Here is a link to the SciAm article - http://www.sciam.com/2001/0801issue/0801hargrove.html - mark Beowulf supercomputer) existence. One linearly, so specific task. projects 486's read about shelf PCs

I read about a major company, I think it was HP, that has created a Beowulf cluster (a group of cheap PCs linked together to create a supercomputer) that qualifies as one of the more powerful

Yes you could but it would be faster better and cheaper to build the super computer from faster CPU's.

Are you considering designing an ASIC to communicate with the parallel port of a PC? snip %<-------------------- We are involved

No, a multiplexer doesn't combine signals. A multiplexer simple allows one signal to pass while blocking another (simply said).For a complex robot like that, I would most likely use digital

I want to make a complex robot. To keep it simple right now I just want the robot to send video, temperature, and altitude. Maybe even some other things later on. I was thinking I can go digital or

I have used a LM140 temperature sensor, whose output in 10 mV per degree Kelvin. I ran the output to a 10 bit A/D converter input on a PIC microcontroller. After scaling the data I then output it from

Optical Isolators can be used for analog or audio signals. You just have to understand the charactoristics of the device you are going to use. A photodiode/ phototransistor pair functions much like a

verhap, Did you have the scope in DC mode. If it was in AC mode the input capacitor might DC shift the voltage. That's. what the capacitor does, it removes the DC component and 'averages' the output.

Just Catching up on my old email reading so someone may have answered already .... Yeah ... what happening is the the oscilloscope is probably set to "AC" coupled instead of "DC" coupled input. It's a
