Which of these two PLC vs PAC & PC vs PLC videos do you like the the best? (Please vote thumbs up on the one you like best.)

Feel free to share with buddies too. :)

Or do you like this one best ...

Hi,this is Daniel,i am a engineer professional in prototyping and
tooling in China.Hope we could learn more each other in here and also
hope have an opportunity to work with you. (Prototype and Tooling life in Shenzhen)

By the way, I was successful at networking all those process automation controllers via wifi. It was cool. If anyone needs details how I did it, just ask.

To James Jones:

I know a couple of companies in the micro-machining area that have already been adopting micro linear motor for their applications. In addition, do you consider peizo-electrical stages for this type of applications?

Have a project comming up where I need to set up 4 laptops to connect to 1 Allen Bradley controlLogix via wifi and a linksys wireless router. If anyone has any advice, tip, links to instructions that may help wirelessly connecting all classroom laptops to a PLC (ControlLogix PAC actualy:>), let me know. Thanks

Capacitive sensors give very high performance. Unfortunately, they require a driver system and generally some tuning. Optical reflective sensors can require a bit of dong to make work well for a gear, but they are very cheap, come in a number of packages/voltages/logic rules, and do very well if they are able to be kept clean. Some models can discriminate distance surprisingly well, and this means even smaller teeth can work.

To state my objective more plainly: does anyone in this community have an opinion as to the difficulty or feasability of designing a linear motor that can be built using a coil winder and a small, light CNC mill? TIA, James

An often overlooked encoder for some low to moderate speed applications is the optical mouse chip. It can work with performance similar to a 1024 cpi linear encoder, can provide feedback for multiple axes (the output is a vector rather than a simple quadrature or count/speed), and is relatively easy to implement. Surface characteristics are important but can be very flexible. They tend to get contaminated in dusty environments. They also have trouble with cumulative accuracy and require an independent home system of some sort. It can only handle several inches per second well. But the shortcomings can often be addressed for a variety of applications. A $3 to $7 chip with built-in serial capabilities that accomplishes what a lot of encoder strips, packaging, and software development would normally do is an attractive option.
