I am new to process control software. We are working on a solar steam project that will require some form of automated control. We need suggestions for software (preferably open source and will run on a windows pc) that will handle temp and pressure data aquisition. The software should also be able to affect small electric motors based on the data parameters. Also any recommendations for temp and pressure (psi) sensors would be greatly appreciated. Thanks for any suggestions

Can anyone help, RC control problems

I have these controls http://www3.towerhobbies.com/cgi-bin/wti0001p?&I;=LXLDP9**&P;=MLOn the receiver end each channel has 2 negatives and one positive so you can switch polarity. My transmitter is not doing anything on any channel and I get constant current flow in one direction even when the transmitters off. I don’t know much about these types of controls and I looked through the manual and can’t find anything to help. Is there something wrong with the controls or is something else going on?

Basic RF control transmission

My goal is to press a button on my transmitter side and have the receiver flip a relay - that's all.  It's probably the simplest possible use of RF technology...  and it's almost impossible to work out on google.  I am trying to transmit and receive just a simple control signal about a range of 300m, so dismantling 27Mhz toy cars is not an option.   Has anyone successfully made a simple RF circuit before? I can buy a 433Mhz transmitter with this range, but they take FSK or ASK modulated signals.  From what i can tell, there is nothing simpler than the 'OOK' version of ASK modulation for transmitting signals.  If I'm wrong, please correct me.  Otherwise, if I'm stuck with FSK or ASK.  I found one site (bottom of PDF: http://www.edn.com/contents/images/101101di.pdf) providing a simple circuit to produce FSK.  I was hoping for something simpler, but if you think this is the easiest way, i'll give it a shot. Can someone guide me towards the correct ICs and circuits to create this project? Thanks in advance for your help

How can I sequence several small motors. Answered

Wife approved Home Theater ​I plan to build raised panel cabinets that also hide home theater speakers and 60" screen. Open display/bookshelves sit between the speaker garage and the 60" screen. The raised panel (I'll make with my 5hp shaper) covering the speaker will roll over the display cabinet allowing the speakers to move out into the room on motorized platforms. Then, the speakers will rotate on a motorized turntable  to the desired position. Next, the two panels covering the screen will move under the speaker panels and also cover the display cabinet plus a little of the garage space. I want this to all be initiated with the push of a button. The motors will all be sequential in the above order. First, the speaker panel can roll until it hits a button, next, the speaker platform movement could be controlled by motor revolutions as in a stepmotor and would stop the platform at the right spot. When this action is complete, the speaker rotation could also use a step motor count. Next, the two screen panels will roll under the speaker panels until they hit a final stop button. I will need a central controller to manage the sequence order. I am familiar with Fishertechnik robotics controllers but I'm hoping that someone here can give me some suggestions to make this work. Thanks for reading. Chuck

Easy/cheap way of halving the mains fequency in order to halve the speed of a single phase electric induction motor?

The problem is to slow the speed of an electric grinder down so that it does not burn woodturning HSS chisels during sharpening. I thought of full wave rectifying the mains and feeding it to a so-called "H-bridge" consisting of four SCR's. The SCR's on the top and bottom opposing sides are triggered together as pairs. Each pair of SCR's are triggered for two consecutive half cycles and so on. Might this work?
