"Oh hey I've never heard of "Coarse" interesting. " Hey man anytime you need to brush up on electronics give me a shout. I am always there to help out. hehe Light filtering, as in a prism?

http://www.fiberdyne.com/products/multiplex.html#top also this one,

That link has some interesting stuff. Check this out: http://www.fiberdyne.com/products/cwdmintro.html Precisely what you brought up first.

Keith Applications will vary, but the concept I build will be based around the Propeller multiprocessor. Others will have their own interests as well. I have several uses in mind, but nothing nailed down yet. Possibly a continuation of the small business and hotel scenerio we discussed...

itsmoked got me thinking about looking into the idea of running a fiber with two trancievers at each end. I am searching for hardware that could filter the colors right now. Most likely that route will require major hardware and cost, but is worth a slight departure to get some basic...

I thought that the modem limitation was more of a wire length/noise problem. The speeds can vary, this is just for experimental purposes at this stage. Your idea is interesting Keith. I assume you are referring to full cycle sine waves. Would a half cycle sine wave function as well in this...

http://circuits.iwarp.com/fulldupidea.jpg I am just getting into serial communication and was discussing Full Duplex on a single wire with someone, neither of us had a good solution, so no better place that Eng tips to find out whats the story! Q. Is it possible to have a single wire(not...

For video applications, have you checked out the Parallax Propeller? It does video easily. There are objects already written for it as well. http://www.parallax.com/propeller/index.asp

Photos on the way in the near future!

That is an excellent point about the resolution. I appreciate the reply. I am ordering the part below which decodes the quadrature into up/down clocks on separate outs, but I'll look in to using the additional absolute output at well. Out of countless hours of digging I haven't seen any...

Hello I posted to another forum but probably should have posted here instead now that I am a bit more informed: Could someone please describe what the concept is for using a shaft encoder on a stepper for tracking with a controller? I want to learn what is the most accurate way to track...

This is not the best are to have posted the question, I am rephrasing and moving to Electric motors and motor controls, as that seems more appropriate for the content. Thanks

Thanks for the info. I am currently programming on the Parallax Stamp BS2P40 as it is easy enough to program with no lower level skills. After I get the project totally coded I am going to have someone transfer that Pbasic to the SX chip for which there will will only be minor syntax changes...

Thanks guys I'll read up on those products. The 2 part epoxy I am using is not working out as expected, it stays somewhat flexible when it is cured, it is a thermal potting epoxy, so it really isn't designed for a robust hold. The epoxy has to be carefully poured into a mold and cleanup is...

Hello all I have a pretty simple question (I think) for guys that are familiar with steppers and encoders. I am getting a nema 23 stepper from US digital with an E2 encoder, that will go into either a LS7183 or LS7184 "Encoder to a Counter Interface IC", then output a clock and direction to...

I have been trying experiments with various epoxies, and under heat in the anodizing process, the part has been bending slightly without the use of a jig attached. Using a jig means creating the same number of jigs for each part sent to the anodizer, plus the anodizer has to take it off to sand...

Hello, I am looking for some advice with gluing some metal together with a black epoxy or plastic that will sand nicely, and support heat to 300 degrees in an anodizing vat. I have a product that requires several pieces of small machined aluminum rectangles to be assembled together with .05...

The AC convention is interesting, but In the event of power out you are not going to communicate unless AC methods can talk when the AC is down just as well (excepting the case of an AC backup). My system is battery operated and will run for days on its own, so I'd like to consider a system to...

Ha! Well It must be the sleep deprivation? A "unit" would consist of one complete door system operated by a microcontroller and touch interface. In the above example of a home or small business concept, 16 or less "units" are connected to one master processor attached to a PC for monitoring...

Hey I got a question now that I am underway programming the thing to replicated the logic stuff. When you are programming, to what extreme do you go towards building the ins and outs to demontrate the real project? I have maxed out this little built in bread board on the demo kit and am...
