A few people i see have been trying to make a "stinger" for RQ out of dvd burner lazers i would be interested in learning more of this project as i am currently in the process of building a "shock Lance out of a $2.50 led Shock torch bought at a local jokes and gags store, a telescopic arial for the actual shocking lance and a slide on bracket for the back of RQ's head so far i have found the head is the most ideal place to mount the lance as u can move the head as much as you want via the remote, the joy of this mounting design it allows for rechargable detachable accessories that dont void warranty. Currently i have a headmount headlight for RQ on this connector style and a telescopic super magnet so he can collect my screws i drop lol and my shocklance (in Progress) another idea was mount on the front near the animation led so that accessories protrude out far enough that he can use them  with out tripping his sensors but eitherway the device will be published on here very soon by me complete with pics .......
