I made this prototype booster this weekend.  It's an inline booster using the TI 4050c.  It is not variable voltage, just a fixed 5 volts.  It works really good.  I wanted to make it portable so I could use it on any of my mods.  I used 1/2" coupler and end caps with just enough 1/2" pipe to hold it together.  It looks big (tall) but it's only slightly longer than an ego with an ego booster.  It hits like a champ.
