    Siemens screen pinout?

    I'm looking for a datasheet or just the pinout of a C60 screen (model LM15SGFNZ07). It might be made by Sharp but I can't confirm that. Thanks

    WTB TFT controllers

    I'm looking for 17 TFT VGA 640x480 contollers. All I can find online is contollers that can do 640x480 but go up to 1024x768 so they are expensive. I've bought two Digital View ones from ebay for ~45$ over a span of a year but don't want to wait 17 more years for the rest  :P . Doesn anybody...

    HP VL-609 Motherboard manual or any ideas?

    I saved a motherboard from the trip to the dumpster. It's from a HP machine and I can't find no info for it. What puzzles me is the front panel connector. It doesn't have the usual PWR LED, PWR SW, HD LED etc, pin header. There's only a six pin header labeled "FRCNT CABLE". So, does anybody...

    Camcorder viewfinder

    Are camcorder viewfinders (or LCDs) easy to connect? Do they just have video-in or some more complicated format? Nikolas

    Hard dsk motor

    I dismantled a dead hard disk and I can't figure out the main motor. Is it a stepper? It has 4 contacts so I thought bipolar stepper. However if it was so, the two pairs should be isolated to eachother which is not the case. I tried to apply voltage in a sequence, it acts kind of like a low...

    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

    Ok, guys, I made the attached circuit and is working. I substituted the red LED with an IR one and it's still working. Should I change anything? Am I pushing the IR too much or on the contrary not getting all I can out of it? If I want to use 4 LEDs I guess I should change the 1K resistor...

    Which program saves *.pcb files?

    I have a zipped project (can't remember where I found it) with the boards in *.pcb format. Which program opens them? Any way I can import them into Eagle? 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...

    Force sensors

    Me and my crazy ideas again! I want to make a realistic replica of the F-16 SSC (actually a joystick which doesn't move). I found these sensors:http://www.tekscan.com/flexiforce/specs_flexiforce.html I want to make some changes: I want 2 sensors per axis. When the stick is centered both...

    PCB software

    1. I'm giving Eagle PCB a second chance. This time I managed to get something going but have some questions. Most important is how do I print just the pcb traces (something with layers?). 2. Anybody knows anything about the IDF standard? I'm working with Autodesk Inventor and it is supposed to...

    Variable Freq Drive

    I'm building a CNC mill and need a way to control the spindle speed from the PC. I've found circuits to control DC motors from the software (TurboCNC). That is OK for my "test vessel" but later I'm gonna need something to control a 2-3HP 3phase AC motor. I've seen commercial VFD's but no...

    CD changer protocols

    I would like to interface an mp3 player to the CD changer bus of a car stereo. For the time being I'm using a portable mp3 player with a casette adaptor. I would like to be able to use a player with a huge hard drive and keep out of the way. I found a this site (http://www.k9spud.com/vwcdpic/)...

    Hello everybody!

    I just registered and thought I should introduce myself. I'm Nikolas from Athens, Hellas (Greece) I'm a Mechanical Engineer and a newbie in electronics. I find them very interesting, though and I'm seriously thinking of going for a second degree on that. Hope I can pick your brains from time...
