    Infra red LEd's for night vision, "color"

    I see a lot of Ir Led's that are 870nm wavelength and 940nm wavelengths. How does it affect what a digital camera sees? I understand color and wavelength, but never compared the 2 side by side. Thanks Jeff

    Latching Device

    The clutch mentioned is only to protect the motor from stalling when the actuator reaches the end of its travel. Typically, the door lock is done by time from an alarm or body control or even your finger. If you kept power on the door lock all the time it would eventually fail. Tell us more on...

If I disconnect power the program is still there, even after months. I can't remember but I think the liscence was on one of the discs and had...

    Hi I have one of these at work still from an ole project. We keep it around for R&D. I have good news and bad news. The CPU fault usually means that there isn't a program installed in the CPU. The Prom that is missing isn't a big deal because there is a battery backed RAM. The bad news is...
