    New to this...I want to replace my car's mirrors with rear-view cams.

    Have you thought that the image will be backwards? You'l need to flip it horizontally

    New freeware to draw PCB

    Can it export the 3D view in a popular format like *.dxf *.iges *.sat *.stp etc?

    How to basicly use a STEPP MOTOR

    This is the simplest driver for bipolar (4-wire) steppers. I used BD239C and TIP30 transistors and all resistors are 1K. It uses phase drive instead of step-dir signals.

    relays - SPST, SPDT, DPST, DPDT?

    Well the power circuit is just a switch, the control circuit is just what moves the lever. Now think of a simple On-Off switch with two connectors. It's a simple throw (one On position) simple pole switch (SPST). Two such switches operated by the same lever would be DPST. If it was On-Off-On...

    IRDA MOTHERBOARD INTERFACE HELP!

    Here's the PCB, still looking for the schematic. It has SMD parts but it's simple enough. I can post in vector format if you want (*.eps etc).

    IRDA MOTHERBOARD INTERFACE HELP!

    1) It might. I bought a TFDU6102 for such a project and it looks identical to the unit I took out of a busted 6210. 2) I have one, let me dig that up. Funny thing is there's no IRDA plug on my new M/B. I was looking for one because the old one did

    Potentiometers with center detent?

    I've already done that. I got 3 slide pots with center detent from a busted stereo but I need rotary ones. I got one out of an old 14" monitor but need 3 more... I don't want to start dismandling working appliances... ;)

    Laser questions

    Ok, thanks. Next time I canibalize a CD-ROM I'll be more carefull... How yould a circuit that uses the photodiode look like?

    Laser questions

    I used the first. It's not a disaster if I burnt it, I'm just trying to understand lasers. How can it give light if it's burned? Can the "simple LED action" the guy describe be on if it's burned? Nikolas

    Laser questions

    So, I had this laser diode from a CD-ROM, with the help of this site: http://members.misty.com/don/laserdio.htm#diodct2 I was able to find the pinout. I powered it using this schematic: http://members.misty.com/don/laserdio.htm#diodct3 I pointed the beam to the wall and looked through my NVG. I...

    LED questions

    I've seen IR emmiters for remote controls, what's their difference from ordinary IR LEDs? Narrower beam angle?
