    high powered LED project - newbie to electronics

    Well this website is obviously the only one you should be using :) So do you have an LED in mind? Surface mount or through hole version? 100 lumens isn't that bright, FYI they do a lot brighter LEDs but white LEDs are currently the brightest and the brightest module I have seen is 6000 lumens...

    Basic LED help please!

    Yes good idea as long as he has the space for this. He might also want just one LED for a reason. Maybe he can let us know. Adam

    Basic LED help please!

    The OP asked if 10W were available.

    LED viewing angles?

    Good Idea Harald

    LED viewing angles?

    You can get some very wide angle LEDs now the widest I have seen is 150deg. Try some wider versions and also move the LED further away if possible. If you can't do that then have a look at LED collimators. Adam

    Yeah they have come down in price a lot. You can also get Dremel type tools for less that £30

    Yep they do exists. Here are a few. http://uk.rs-online.com/web/p/through-hole-fixed-resistors/6661724/ http://uk.rs-online.com/web/p/panel-mount-fixed-resistors/6835997/ http://uk.rs-online.com/web/p/through-hole-fixed-resistors/6253402/ Adam

    Paid electronics simulator

    Under £20.00? Don't know of one that cheap. Tina from design soft do a student version limited to 100 nodes for a reasonable price. But beware the trial version is likley going to be the full version. You need to check out the options for each version. Adam

    A dremel type multi tool in a drill press is good for small to medium holes. For drilling larger holes a standard 3/8 inch chuck rechargable drill is what I use. Adam

    Audio aplifier with faulty 12VDC Power supply

    Ok cool. I am guessing it has some sort of transistor/s to switch the coil of the SMPS. Could that be the issue?

    Control the amount of current

    Why would taking a motor up a hill cause it to draw more current?

    Control the amount of current

    If you did it in software and measured the peak current and then worked out the average time from your duty cycle. That would work Adam

    Hello all

    Hello Kad

    Need a wireless monitoring solution.

    Are you looking at making something or do you want to buy something. How many sensors are you going to be using? How far do you need to transmit? Adam Edit: Found this website http://www.ni.com/example/31452/en/

    Help requested for a circuit design

    My word they do start young these days, and he types better than I do :)

    Control the amount of current

    For the current to change in the load you would have to do one of two things, change the applied voltage or change the resistance. I don't see how this can be done with a transistor being operated from a micro. The micro will output the same level regardless of PWM duty cycle and the transistor...

    Control the amount of current

    This sounds interesting. Can you explain a bit more about what you want to do and circuitry you want to control. Adam

    Troublesome powersupply

    Good work mate. I hate circuits without any values, I am sort of lost without them.
