Newbie - potentiometer no voltage don't drop

Hello

http://screencast.com/t/NTI2ZDBkNjM

Please could someone explain why the voltage remains at 12v through the potentiometer?

Neither is there any voltage drop display when I change resistance.

Thank you.

You measure across the fixed part of the variable resistor.  Move one of the probes to the wiper (the Central Terminal with the arrow).

  • drop-down lists on the forms don't drop-down list

    I use Firefox 3.6.16 on Mandriva 2010.2 and for the last two months, the drop-down lists don't dropdown. I thought a patch would come out to fix it or it would be one of my modules cause. There was an update recently and it has not fixed. Today, I've disabled all addons and restarted, but still it does not allow me to make a choice with the mouse.

    There are many similar problems with FF4, but none of the solutions appear to be relevant.

    Anyone got any suggestions?

    < edit > I just disabled all the plugins too but still the same. What I noticed at the time, is that there seem to be two versions of Flash installed, but only the first shows under tools modules Plugins

    There is no need to create a new thread. You can edit your first post and change the title, if you want to change it or I can do it if you post a better title.

    Problems with a menu drop-down does not not can be caused by an extension.

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Tools > Modules > appearance/themes).

    See:

    If this does not work in mode without failure, then disable all extensions and then try to find out who is the cause by allowing both the problem reappears.

    • Choose "Disable all add-ons" on issues to troubleshoot Firefox in Safe Mode to set window to disable all extensions.
    • Close and restart Firefox after each change through "file > exit ' (Mac: ' Firefox > leave";) Linux: "file > exit ')
  • Not by selecting for viewing, but don't drop-down list box option

    Is it possible to have an option in a drop-down list box that is the first thing that people see, but not a selection? The field is mandatory, but I don't want the first option to be shown. For example:

    < select a >

    option 1

    option 2

    option 3

    Thanks in advance

    Nope.

  • Drop-down lists don't drop-down list in Firefox 5

    Since upgrading to Firefox 5, drop-down lists on Web sites, no longer drop-down list. They work OK in IE, Chrome, Safari, et al, and they worked in FF4 - simply no FF5.
    This seems to happen on all websites but I can't believe that something this blatant has not been noticed by someone else, so I think that something unique to my setup.
    I can't fill the box "It happened": the drop-down list does not work!

    Same problem here. Win 7 64 bit, after update to FF5 no Dropdown HTML more doesn't work. I try with all the addons disabled and with a new profile, nothing works for me.

  • Position the Panel - no data - don't drop-down gray

    Version: Captivate 8.

    This morning my Position Panel Virgin.  Yesterday it worked fine.  I worked with position properties in projects in reagent and traditional yesterday afternoon.  The window drop-down list currently shows "Properties of Position" gray and cannot (although controlled and visible tab on the right).  No information shown in Position Panel for all types of projects EXCEPT responsive projects.  The control panel features of position well for existing and new projects of reactive nature.

    Actions:

    The CP is closed and reopened.

    Deleted the project cache and restarted my computer

    Open to new and existing non-responsive type projects to test availability.

    Search preferences with open projects and any open project.  I can't find an option controls the properties of Position function.

    Any suggestions?

    Board position only should be used for projects of a reactive nature, makes no sense for traditional projects.  I'm pretty sure.

    Position and the size of the objects in the normal projects are available in the Options tab of the properties panel, not in the Panel Position.

  • Don't drop the 6s for MacBook iPhone no devices found

    Hello

    at first I wan't to apologize if my language is bad, I'm not very good in English.

    Now to my question. I have a MacBook Pro Mid 2009 running OS X Yosemite. I tried to send a photo from my iPhone 6 s more to my Mac via AirDrop, but my Mac does not show my iPhone in the Finder and my iPhone also does not show my Mac. This could be a compatibility issue? Maybe someone of you knows the answer?

    Greetings

    Hello Dominik,

    Welcome to the communities of Apple Support!

    We understand that you want to send a picture from your iPhone to your Mac via AirDrop, but the devices do not see each other.

    The reason for this behavior is because of Mac model you are currently using. You have the MacBook Pro (mid 2009) will not meet the requirements to use Mac to Mac AirDrop, but to send or receive with an iPhone, the Mac must be a Yosemite 2012 or later running or a later version.

    The following article explains these more detailed information:

    Use AirDrop to send the contents of your Mac - Apple Support

    Release system requirements

    Send items to an iPhone, iPad or iPod touch, or to receive these devices, you need a 2012 model or later Mac with OS X Yosemite or later version, except the Mac Pro (mid-2012).

    To send items to another Mac, you must:

    • MacBook Pro (Late 2008) or later, excluding the MacBook Pro (17 inch, late 2008)
    • MacBook Air (late 2010) or later version
    • MacBook (Late 2008) or later, excluding the white MacBook (Late 2008)
    • iMac (early 2009) or later version
    • Mac Mini (mid-2010) or later version
    • Mac Pro (early 2009 with AirPort Extreme card or mid-2010)

  • Drag &amp; Drop and start

    After the Fusion 8 upgrade, I noticed that I can not drag and drop between Windows7 and MacOS (10.10.5)

    MORE when I run Merge (automatic start of Windows), NOW I get a "Windows is not stopped... successfully." "whenever I start, even if operating manual.

    I did nothing else than to pay and install the upgrade of Fusion 8.1

    I'd like to go back the way it was... drag & don't drop between Windows and Mac... no error starting Windows... suggestions?

    Thought of her old post on a similar problem.

    Once the update of Fusion to the 7 8 tools VMWare had to be installed... Once installed the two drag & drop began work and error starting Windows stopped... would have been nice to know to reinstall the VMWare Tools.

  • How to get a water drop and rebound effect

    User newb here. I don't know if this effect is named, but I have a still image (a book cover) and I want it to appear in the frame (on top of the video) at the top, then bounce a bit, as if he were hitting the ground. I know how to drag in the framework using the Position and speed by the image, but I don't know how to do the effect bouncing. I'd be happy with a stock effect, if any. Thanks in advance.

    Hi Cheryl,

    This kind of thing is best done in After Effects, but you can get a decent effect in Premiere Pro. You must manually animate the position of book cover to get the rebound effect. Think what a bouncing ball looks like when you bounce on the floor - each new position where the ball reaches its highest point is a little more close to the ground, and when it hits the ground is a little further away from the previous position (except if it bounces perfectly right from top to bottom). The time between logs positioned continuously decreases because the ball is short of energy.  For example, create a keyframe position for each new post of top-of-the-arc and each new position of contact with the ground.

    You will need to change the temporal interpolation of keyframes to include an ease in or deceleration, which is best and gives smoother animation.

    See you soon,.

  • Can cancel you &amp; quot; acceptDragDrop() &amp; quot; using manual Drag-and-Drop?

    I have an AdvancedDataGrid (ADG) with the feature manually drag-and-drop in. The user can only and drag within one ADG. I do this in order to validate the elements that can be moved, and where they can be recessed. I ran into a problem, however. In my dragEnterHandler() replacement, I call DragManaged.acceptDragDrop () if the user drags an item on a valid element. However, be they don't drop off the item and continue to drag the element around the ADG and roll on an item that is not valid, there is no way to undo the drop.

    Does anyone have any suggestions?

    I thought about it... I use the itemRenderer to the dropIndex like the acceptDragDrop() target and add a dragDrop event handler/listener to the itemRenderer.

    Works like a charm now.

  • Measurement of resistivity with MyDAQ on TEC ca

    Hello

    I would like to ask for advice: we would like to measure resisitivity Peltier-elements. If we use the DC method, due to the cell voltage-Seebeck effect, we don't get the value of the true resistivity. The common method to use the measure of ca in the case of these devices. I would like to know if it is possible to use a device of MyDAQ for this task? As a first approach do us not need more precision, it would be more as a test of 'broken-element' (there is usually a significant change in the nominal AC resistivity value indicated by the manufacturer).

    What would be the best way to make a simple measurement? What if I use an analog output of the MyDAQ lets say at 1 kHz, and I drive the Peltier element with this AC voltage source? I connect a resistance in the series, and I measure the AC voltage on that drop. After the results, I could calculate the current and the resistance of the AC of the Peltier element? Of course, I choose a resistance so the MyDAQ can drive the network.

    What is your opinion, where to start?

    Thank you!

    Sounds like a good chance to learn more about these devices. In these conditions, I would do the same thing: try with what you have.

    A quick glance at the plug MyDAQ it is clear that the current of the AO is limited to 2 my. I probably set the zone of OCCUPATION for about 2 V and use 1000 ohms in series with the Peltier device. That will keep the current in the 2 limit my. Two lines of AI to measure the tension on fixed resistance and the Peltier device.  Then, you can calculate the unknown resistance.

    If you were doing a production test or did the measure with a DC bias, I advise to use a transformer to couple the AC component in the CC line. This becomes a little more complicated to implement, but has much to versatility.

    Please post after you have tried and let me know what you found.

  • Shadows look too solid printing

    Designer newbie here with a question of drop shadow.  I'm working on a project using the photos with a white line vintage style squares and a drop shadow.  It looks great on the screen but I come back just one page of the printer and the shadows are much too solid-looking on the paper.  Almost looks grey boxes around the photo.

    This is a personal project and whenever I print, I have to go to the FedEx Office to pick it up, so I don't want to just play.  I hope you can help me.  How to look more subtle?  I tried to lower the opacity and they looked like just more light gray boxes around the photo.

    I use Adobe InDesign CS 6Here are the settings that I use:

    Screen Shot 2015-03-04 at 2.12.04 PM.png

    Thank you!

    Here, Office of FedEx uses a few different brands of digital printers. And they have two ways to print, their own software and Acrobat. I never had great prints of their PPP software. Since Acrobat I, however. So I simply ask they do (and most of the time they do it anyway).

    I create files using the preset PDF/X-4 most of the time. Otherwise, I simply use the highest compatibility PDF version (if if the software I use PDF/X-4 or not in operation). My shadows come out as good as their different printers can print.

    Rob is correct. RGB is better for their printers if you are careful to stay in the range. Because this sort of thing I meant to printing at FedEx is not high-calibre (Hey, their practice, the only thing in their favor), I don't take the time to create RGB. They are circular quickie, flyers and other. Something of importance, I send to the local printer I used for eons.

  • Is there a way to 'smart move' a clip?

    So I'm quite a newbie here and probably don't have the right term for this...

    I have four clips-

    A B C D

    I just want to go D in order so that the new sequence will be:

    A B D C

    But when I do drag and drop it appears just beneath it.

    Sort to move smartly, it fits into the slot between the other two clips and push successive clips before the right amount?

    Try ctrl + alt while moving.

    1 problem is that my 15 000 pictures present date instead of filing in the events as they have always been.

    2 mail seems lost several mailboxes that I had installed in the margin to quickly drag and drop INFO and interesting technical questions.

    3. I have a stream of photos don't drop-down after a few days, which will not go away it just keep reappears not no this that I still need it for.

    4 never used the cloud but considering buying iPad and dumping of my old Apple laptop not likely with the capacity of 128 GB.

    A year ago, Apple went from iPhoto to the new Photos app. If you have questions Photos I would re-post in this forum. Can be found the link to it by clicking on the Photos for Mac

    About your mail, try to rebuild your mailboxes and if this does not work, you may have to re-create the mailbox store that you had previously.
