    Luxeon star LEDs - heat dissipation?

    heat resistant epoxy is NOT a good idea. you need something that CARRIES the heat through to the heatsinks where it can be dissapated. as for using them I would assume it depends on your intentions, have you factored in the need for a regulator to be used? also it depends on the aount of...

    Squeeze that battery

    ok let me putit very simply watts =amps *volts. if you increse the amps you half the volts.if you increase thevoltsyou half the amps. the thing youCANNOT do isincrease the watts without increasing either the volts (withoutdecreasing the amps) or vice versa

    build a sensor that can calculate distance between itself and sub sensors

    well if you are using the same length of wire put it on a reel. get one of the countless ways to count how many times you wind it out. if you use this approach you MUST factor in the fact that the outer layer will be much wider that the inside layer. edit you could also use a "pulley" and...

    build a sensor that can calculate distance between itself and sub sensors

    ok think of it like this. the sensor prime sends out a little packet of data. the subsensor simply recieves it and sends it back. when the sensor prime recieves it back it simply does the following equation speed of transmission / time it took to get there and back / 2 (as it travelled to...

    build a sensor that can calculate distance between itself and sub sensors

    simply put all you do is calculate the speed at which the transmission goes, then divide that by the time(this is nanoseconds) this gives you your distance.

    Can you help me develop my invention?

    the issue here is that we have a rough idea of the loc8tor system. we cannot give exact details without getting one, pulling it apart and going through it piece by piece. but to answer the first question they don't use as much power as most other items on the market..... to answer the second...

    USB Extension

    use a usb male to usb female... there are various lengths. the issue however isthe length. as wire is a conductor not a superconductor it has resistance. the further the distance the more drop in voltage and therefor the signals get lost. A trick you can use to extend this is to buy a USB hub...

    Can you help me develop my invention?

    just an addition here. poorfornow I work security while on a patrol of a construction site I noticed I was walking long distances to monitor this site. I came up with a simple sensor that would detect motion on the temporary fencing, a break in said fenceline(they are panels pretty much which...
