    Double pull double throw switch

    First of all it's Double Pole Double Throw. A Single Pole Double Throw (SPDT) would only have pins 1,2,3. The signal you connect to pin 2 will be routed to pin 1 when you put the switch to one ON position and to pin 3 at the other ON position. When it's at the OFF position pin 2 won't be...

    Oscilloscope tube D18 141GH datasheet?

    How hard is it to make an oscilator if you have a tube? I mean just X-Y, no timing circuits. Nikolas

    3-Axis Stepper Controller

    RobiD you could try a flexible shaft to keep the drill furter away and to keep the spindle lighter. BTW any answers about this? I thought it was a cap (it says 0.33uF) but when I measure it it doesn't seem like one.

    3-Axis Stepper Controller

    Can somebody tell me what this part is? I'm using an AC motor from a busted drill for the spindle, and this was connected parallel to the switch. Is it some kind of a filter? Should I add it to the relay board I'm making?

    Program a menu

    In VB it's easy as cake: Tools -> Menu Editor Add your menu items, keyboard access etc. Then double-click the menu items you just created to assign some code to them. In C I have no idea, sorry.

    s-video to vga

    I'm not an expert but I think so. You have to extract Sync from the Y(Luminance) signal, divide it to H-sync and V-sync (using an EL4583C or LM1881) and decode the C(Chrominance) signal to RGB (no idea how to do that, sorry).

    PCB software

    I tested Target3001's IDF export feature: I opened one of the sample projects, exported to IDF ane opened it in Inventor. Several error messages came up, and the result wasn't high end 3D stuff, but it worked and it can be usefull. After finishing with the board design I can switch to Inventor...

    3-Axis Stepper Controller

    They are actualy seven 4k7 resistors with one pin of each resistor connected to a common pin. You can use discrete resistors, though I don't think there so hard to find. Don't search for the specific code, ask for a 1-7 resistore network.

    VGA splitter - cropper

    I made a litle graphic of what I want to do. To have the video card working at a high resolution and display four parts of the image on four small monitors at lower resolutions. E.g 1600x1200 ->4x 640x480 (with offsets) or 1280x960 ->4x 640x480 (no offsets, the image divided equaly to four...

    VGA splitter - cropper

    What I want Is the left part of the original picture to be missing! But if I send a H-sync to the first output wouldn't it start displaying what's there (having skipped the left part) right away? Why would it display black? Thanks, Nikolas

    VGA splitter - cropper

    I want to cut four parts of a VGA output and direct them to 4 outputs. That's what I was thinking of doing: Use a PIC to monitor the V-sync and H-sync lines and control transistors connected to the RGB signal. When the PIC detects a H-sync pulse it will wait for a set time (in order to create...

    3-Axis Stepper Controller

    I open them in Corel Draw. Adobe Ilustrator will do too, and many programs can import it (even Word if you added the appropriate filter during install).
