A guy I went to school with made a liquid cooling heatsink with a peltier device. It was to keep a chip steady at a certain temp regardless of power consumption.<p>If I remember correctly, he use a small microcontroller hooked to both a relay (for the pump) and a couple temp sensors (one on the heat...

The 80 watt iron is for things like voltage regulaters that have their backs soldered to a power plane. Or pulling out large SMT or through hole capacitors. Those parts suck the heat out of the little irons and takes a minute or two to pull off.<p>Yeah, but most stuff gets done with the little guy. ...

It will be good to learn on them as far as PCB soldering goes. <p>for small resistors and most surface mount components, use a 25 watt iron with a fine tip. For through-hole or Planer componets, I use an 80 watt iron with a high density tip.<p>Make sure you have a clean tip on the iron. Either use a...

I'm thinking about making myself a wireless home security system. I was leaning towards a very small transmitter sits idle until a sensor (either laser or magnetic) detects a break. <p>The several transmitters would feed a central reciever that can be armed/disarmed and sound an alarm.<p>I've seen s...

Hello All.<p>I am looking for a laser sensor/detector that works similar to an IR detector.<p>I am using it in several projects that I've used IR in (like comm. hardware, laser tag w/electrostatic discharge notifiyer) and want the coherence and intensity of laser light (to fight ambient interference...
