Engineering Roundtable Episode 15 - Infrared Shark Project with Chris Taylor 

was the dude that invented the tv-b-gone working at a bestbuy and wanted to make his job easier?

Thanks for explaining this - saved me a heap of time! Cheers!

Does anyone know where the Arduino source code for the IRShark is?

I would like to contact Chris Taylor about this project and helping in another.

Hmm, how long has 38kHz been used? I recall a few instances years back where devices would do some random things, maybe in direct sunlight but if it's discriminating to 38kHz you wouldn't think the sun could trigger it.

Good video! I've been wanting to make something like this for a while, and that library is exactly what I needed.

how to modulate IR signal to 38KHz with ardino ?

when you have a high voltage that frequency is IR? I'm having trouble to relate the 38Khz with the IR frequency which ranges from 300GHz to 430THz

You are such a good guy...plz shear us the skitch

Just a point to make. There are infrared receiver diodes, receiver transistors, and receiver diodes, etc with extra circuitry built in. The one he is talking about is the later. It has a circuit for doing functions such as gain control, band pass filtering, and demodulation. So what you get out is logical ones and zeros. If however you try to use just a basic IR diode detector or IR transistor detector that doesn't have that circuitry then some, if not all of those function must be done either in hardware or software. If you don't have one with the built-in circuitry then you need to know how to deal with those issues. Best bet is use one with the circuitry built in. A lot of the hard work is done for you and they do a nice job.

excellent explainations of ir protocol

ok wait, does anyone see that this can be used to get into a car ? That is bad, cars use IR. unless the car's code is too complex for the ardunio ?

Is there a way I can buy that case for that project

You saved my life..

mkay.
