Portal Turret Plushie

By: kurt

Deadly, yet adorable, this plush turret from the game Portal talks and responds when you play with it. It senses when you pick it up, knock it over, or walk in front of it. The stuffing and soft fleece skin make it super cuddly, too!
Inspired by Up, not North.

Steps

31. Insert buffer

Insert the SN74AHC125N in the slot for IC4. Again, line up the dimple on the IC with the markings on the circuit board. See how my IC didnt lay flat on the board because of R6. This is why I recommend you solder down IC4 before R6.

32. Solder buffer

Solder down IC4. The SN74AHC125N integrated circuit has a description of "Buffers & Line Drivers Tri-State Quad Bus".

33. Insert regulator

Insert the 3.3V regulator next. Make sure that the package lines up with the outline that is printed on the circuit board.

34. Solder regulator

Solder it and clip the leads.

35. Insert header and button

Inser the 6-pin ICSP header and button next. The button is symmetric and can go in either way. The same goes for the header.
