Once all tests have been successfully completed, a new card USB for servo motors is available in opencockpits.http://www.opencockpits.com/images/USBServosp.jpgLike with the other cards, you can order just the PCB, the assembly kit or the card completely finished and tested.It controls up to six servo-motors (10 bits of resolution) and 4 A/D converters using USB port.Another items are available now :new circuit for 6 display digit 7 segments.http://www.opencockpits.com/images/pd6.jpgYou can choose now for 3,5 and 6 display digitshttp://www.opencockpits.com/modules.php?name=get_iocardsi

This servo thingy .. is that stand alone ? Or does it require a IO master card ?

This new USB servo-motors card not require Master card. You can connect to USB directly.

>This new USB servo-motors card not require Master card. You>can connect to USB directly.Ferdie, these standalone things are very cool. Instead of doing a master card with interface circuits, just using usb is very clever - and a very good way to start small and expand as you go!Nice!//Tuomas

Hi Ferdie,Correct me if it is not possable.Simple auto-throttle/speed-brakeconnect pots and servos on each throttle to card.Use SIOC to read and compare n1% to pot position% and adjust servo up or down as needed.(FS or PM should keep n1% correct for commanded speed without intervention)Repeat as long as auto throttle is engaged.For speed brake/spoilers:-Connect pot and servo to cardUse SIOC to determine when spoilers are armed.If spoilers armed and aircraft touches ground move spoilers to extended.when on ground and speed below 60Knts retract spoilers.(Probably would need to set SIOC variables as flags to keep track of transition from air to ground etc.)Hope you can understand what I am trying to askSimonwww.desktopflying.co.uk

Yes... You can build autoTH with servo-motors and this perfect logic !But, if you want to retract Throttle when autoTH is engaged you cannot use servo-motors because you have a fix position.In this case you need to use DC motors or stepper motors.
