Hobbyist Patrick Priebe’s inspiration was the comic book character “Iron Man”, who has “repulsor rays” in the palms of his armor’s gloves. Priebe’s device is self-contained, with the battery in a case that wraps around the back of the hand. Simply flexing his hand triggers the beam to fire.

His inspiration: Iron Man’s repulsor ray glove, as seen here in the motion picture with Robert Downey, Jr.
Priebe made a number of versions. He is selling limited numbers (not mass-produced) of kits and assembled gloves on laser pointer forums for $200-500 depending on the version.

Casio America, Inc. (“Casio”) has recently learned that potentially dangerous handheld laser pointer devices are being marketed and sold by Wicked Lasers, Ltd. (and possibly others) that are believed to incorporate laser diodes improperly removed from Casio XJ-A series projectors. Casio has never authorized this unintended and potentially dangerous misuse of the light source component of its XJ-A series Projectors.
Casio specifically instructs and warns purchasers of its XJ-A series projectors that disassembly or modification of the built-in laser module is “very dangerous and should never be attempted,” and would like to take this opportunity to remind the laser enthusiast community of that fact. The unauthorized, unintended and potentially dangerous misuse of the laser diodes improperly removed from Casio XJ-A series projectors for use in these handheld lasers, such as Wicked Lasers’ SPYDER III, may create a substantial risk of fire and injury to users and others. Casio intends to pursue Wicked Lasers and any other companies that violate Casio’s rights by misusing components of its XJ-A projectors or other products to the fullest extent of the law.
At the same time, Casio strongly urges consumers to avoid these unauthorized and potentially dangerous “laser pointers” such as the SPYDER III.
