Sirs2k,

check out IrScrutinizer [Link: harctoolbox.org] and the capturing hardware it supports (IrWidget, GlobalCache, IrToy, Arduino).

@mdavej: For a short time, the Texans in your link offered IrWidgets -- for quite a price (USD 40 or something, considering the cost of the parts, possibly 3 USD). But not now any longer.
