A Quick Piece About The TV B Gone On Stripboard

Well as you may or may not know i dabble (and fiddle) in Electronics & Microcontrollers so after having met the US hackers Mitch Altman/Jimmie Rodgers at a Fizzpop workshop and successfully built a AVR ISP programmer i thought i'd have a bash at making a TV B Gone on stripboard from scratch. Here it be (well attempt #2 t.b.h) , the main circuit was pretty much built 'on the fly' with a homebrew LED driver being a PNP transistor powering 2x IR emitters in series (my calculations are a bit ballpark so it's probably under powered). Does the job though, just a shame the 3xAA batteries that power it dwarf it and spoil the illusion hence them being cropped out the picture.

(PS: The ongoing competition in geek circles with these things appears to be in ever increasing the range, so hang around for the TV-B-Gone bazooka, coming to a Nielsen box near you soon!)
