    thermistor

    also the coding. I find giving yourself a couple degree between on and off a good idea. say for example make it turn the fan on at 40 and off at 30 even lower if you wanted. also you can have the fan going constantly just pwm it as the temp increase.

    i need some help

    hey ogulergun. aside from the witch debate I will help you out. for starters NO you cannot hook up a 12volt panel to a 220v line and expect it to do anything. it requires 220v AC. so for starters it will not have enough juice and its not AC. what you can do though is depending on the battery...

    Walki Talki's

    working in security I will confirm this. we have Icom, Motorola and they walk beautifully. with the more advanced models you can get in and set channels. with the basic models there are preset channels. the only thing that might hinder you is if the model you have has a basic encryption on it...

    Car battery and amps

    the only thing I can think is that when you hooked it up to the transformer a wire came loose or you shorted the transformer. the way you describe is a version that should not hinder the operation of the device. I would however put a simple fuse in the way to be safe but having said that its...

    am I in the right place?

    is the OP after dimming? or is he/she after the ability to make lights go on/off in a line? The way I read it it looks like its a line of LED's that he wants to turn on and off each one individually. so that you have a row of 5 LED's and the bottom 3 are on pressing the + - buttons will make...

    New Career?

    I have seen fruit bats fried on the power lines..... maybe it isn't to do so much with the wires but the part of the body it touches. bats wings are a soft tissue they use to jump between items. a bird uses its feet and last time I checked not many birds are big enough to stand on both wires.
