I'm looking to create an IR Transmitter like the tv-b-gone.
Does anyone know what parts or a schematic would look like.
It would blink at 14Hz or 14.33Hz.
Of Course Use IR LEDs or a combo of them.
How would I make a Infrared Transmitter.

I would look at the TV-B-Gone schematic:

The source code can be changed to suit your timing needs.

A pot is not a timer, it's simply a resistor with a value that can change. If you were to use a timer chip such as a 555 timer, then a pot would probably be a good choice to fine tune your flash rate, but using an AVR chip (like the TV-B-Gone uses), you don't need that, as the microchip handles all of the timing issues.

Ummmmm....
Probably use a 555 timer:
http://www.uoguelph.ca/~antoon/gadgets/555/555.html
Use T = R*C to find the values needed for the resistors and capacitor... (Described more on that page)
Hook up your LEDs in 3 rows of 24, the rows are need to be in series to get 4V a piece... or 4 rows of 18 to get 3V a piece... Then the 18/24 LEDs in each row will need to be in parallel
And you'll need to use a lot of transistors.
That may or may not work/be the best solution if it does work...

The LEDs don't really matter to me.
I'm just going to use this

Why not this one and save yourself 9 bucks?

Ooh, I forgot, the kit was updated, it's $22 and you need to solder it, but, believe me, it will be the greatest investment you make:

Otherwise eBay "AVR programmer", they're as low as $12ish
The one I linked to is by far the best available, though
