    How can i fix fan in my new home

    In the states, the black is supposed to be the 'hot'. But this can get a bit tricky if someone has wired in a switch, etc. So it is best to test the wires with a MM, with the electric on.

    Electric Grill

    Yeah, a 1200W transformer is gonna cost you probably $200 or more. Get a refund! :) http://search.digikey.com/us/en/products/12.8-100/12.8-100-ND/1984719 These aren't even the correct V, but a ~1200VA transformer is easily $200

    Electric Grill

    1. Yes 2. If the stove is purely resistive in nature, then not a whole lot.

    Electric Grill

    So I take it you have no way to get 220V in your dorm room? Any heavy duty appliances around with a 4 prong plug?

    Please Help!

    Well it has to be powered by something. If it has been over a year I would think the batteries would be dead by now, so you could start by unplugging everything.

    Please Help!

    So there was a felony crime committed and you didn't think to call the police?

    Can you help me find these parts?

    Can't you buy some heat shrink tubing and just slip it over the cable and fix the insulation?

    transformer or converter

    I will assume with no certainty that the converter you bought at walmart is nothing more then a step-up transformer. Do you have any information you can provide us with on the light?

    Which Dev Board to Buy?

    I bought my arduino on ebay for dirt cheap from china. I wasn't in a hurry and didn't really know if I would even use it. Well I found a use for it and it works perfectly. So now you have another option.

    Atmega8L using 3v Battery

    don't blame me, the datasheets lied. To be honest, the datasheets give worse case scenarios, the uC probably consumed less power then its max is my guess. Did you read your battery voltage when you where at 20 hours? What did you do with the uC for those 20 hours, was it in idle mode?

    A realization

    Yes, and in the states it is a crime to call the emergency hotline as a hoax. These are all good things because it keeps people honest and as helpful as they can be. Because I do not want a computer telling me how to help an unconscious child. Emergency operators need to help as much as...

    C programming on PIC16F877A

    vick, I was doing some digging today and found out that you can simulate C code in proteus isis. It actually works out pretty well. Have a look at this tutorial here. http://smainj.free.fr/tutorial/ Tutorial1.rar contains the flash files, video you can watch in your browser. 7mb's I think...

    C programming on PIC16F877A

    You probably need to disable one of the other functions on that pin to use it as an I/O From the datasheet So I would try first CMCON = 0b0000111 If that don't work, look at OPTION_REG<5>

    Simple AC transformer question

    I know where you can find a 12VAC transformer that is plenty big enough for what you need. Old battery chargers, Even the smaller ones will put out 10A. Some of the big guys will be capable of 50A.

    NE 555 timer

    Put a transistor on the output to handle the current for the load. Also, you need to add in a diode to the 555 astable circuit if you want a <50% duty cycle. this should help you choose your values. http://www.kpsec.freeuk.com/555timer.htm#astable Without doing the math, the table on that page...

    AWESOME TESTING TOOL!

    I didn't really read everything you had to say, but based on this I wonder why you even brought it up? :D edit: and yes, you might as well offer up a link to something we can look at. I, like most people, like pictures...

    C programming on PIC16F877A

    From the video it is working just like you coded. The reason 1 and 3 come on after all 3 are on is clear. You never set it's state here. LED_1=1; LED_2=0; delay(100000); LED_1=0; LED_2=1; delay(100000); Of course this is only gonna happen after your main{} function runs the first time through...
