    Laptop's Extra Heat Issue.

    I once watched an episode of Bang Goes the theory, he used Polystyrene and a 60 watt bulb, the laptop could do it if you spent say an hour gaming on the laptop lol.

    Laptop's Extra Heat Issue.

    I don't have a laptop lol, but I can't help but feel that heat could easily be used for something else.... ah yeah, how about a metal plate that attaches nicely to the laptop base, that base is actually now a little metal box you can place your dinner, after 40 minutes, it goes ping, you...

    LED Lighting Project

    if you use an LED, be 3.7v or 12v, a Regulator is highly recommended to keep it at a constant 3.7v or 12volts.... and either PWM or a nice juicy resistor to keep it from burning out.

    Batteries Discharge and Recharge time.

    Moha, the more energy you push into the battery the more heat produced, the heat produced is simply wasted energy, so slower the charge the better and the battery will last longer as a result. eg, if a battery is (1.2v 1000mah ) (with exception to the tapering off near full charge) if...

    Smart Card Hacking.

    No, i'm not interested in doing it, but I found 'how' very fascinating... check out this video... (p.s, not that I could do it, i simply don't have the money, and yes it's legal providing you hack your own card and anything you find you don't distribute) Interesting video too...

    Bluetooth arduino

    you gave me a good idea to think about though (for weightwatchers, having all their members (for a price) have internet connected scales and have the data flow directly into their servers so come next visit they can pull up the stats on them etc.... :) - so thanks lol

    Bluetooth arduino

    http://code.google.com/p/casainho-projects/wiki/SdCardBathroomScale You may be dealing with something other than bathroom scales, but i figure reading the data is going to be similar?

    Bluetooth arduino

    you have a bluetooth device connected to a pc. you have a bluetooth device connected to arduino (2 digital io pins to read/write data) The scales i assume interface with the Arduino somehow? have you done that? you are able to read the data?.... i'd probably hijack the data lines to the...

    Generators/Solar Cells in series or Parallel?

    can you imagine 3 240v AC generators all passed through a diode and rectified and then placed in series...... Jacobs Ladder anyone? :D

    trying to regulate dc voltage

    You may need a step up / down regulator... only because of the fact when you idle it hits 11volts, with a regulator there's going to be a certain voltage (depends on which regulator) where by it will drop out, eg, if wanted to power a 12v modem and i stick a 12v regulator from a 14.5v supply no...

    A machine to measure resistors...

    I can't help but think a modified printer to do this would be better, but it's still a lot of manual labor involved... a machine that can measure them and spit them out would be much more superior :D

    A machine to measure resistors...

    I don't mean paying someone to go through 500 resistors with a multimeter... (although that's what I tend to have to do when looking for 1) Could a hall sensor be used? Throw a resistor into a magnetic field then somehow measure the resistance based on how the magnetic field changes? I'm...

    I just had a vision of the future of TV.

    lol,,,, my mind is constantly coming up with new things, I have lots and lots of new ideas and concepts coming to me all the time, but 9/10 way out of my skill range to develop myself, i'm all for Open-Hardware and open source (meaning, providing some company does not patent something and then...

    I just had a vision of the future of TV.

    your room becomes part of the movie experience not something you put up and down once a week, once installed it's done until upgraded type of thing, what next, don't want the sound system, it's a bit clunky like 3D?

    I just had a vision of the future of TV.

    3D? .... been tried many times, i doubt it will ever take off... this however I think has the potential.....

    I just had a vision of the future of TV.

    Really, TV has always relied on Sound and Video interleaved which does a very nice job, esp with the high end sound systems... but I've just had a vision of the future in home entertainment and here's how it works.. Reality meets TV, what i hear you ask. You're watching a scary movie, a...

    Conductivity and Energy storage?

    Batteries came through inspiration from mr volter, using a stack of plates (1.3v each) a capacitor came much sooner through a Laden Jar ...

    Conductivity and Energy storage?

    Supercaps may vary between manufactures, you'd need specs of the actual cap to determine that, i've seen some large caps including ones that act almost like a battery in flashlights... My only concern with supercaps is charging them, take a 2amp/h AA battery, let's suppose you could charge it...

    DC power supply

    People always oooo and arrrrrrr over anything that shows numbers and stuff, buy a Digital Ammeter / Volt Meter wire them up and people will think it's special lol
