Learn how to create laser graffiti

This week, I met with the gentlemen of Graffiti Research Lab Vienna, aka, GRLv, and they were kind enough to break it on down and show me how to set up a laptop, camera, projector, and laser to be a nondestructive and awesome graffiti tool.
The following is copied directly and without edits from the README file as found in the Laser Marker zipfile that you can find in the sidebar at http://graffitiresearchlab.at.

    Trigger Finger

    Stenosing tenosynovitis, commonly known as “trigger finger” or “trigger thumb”, involves the pulleys and tendons in the hand that bend the fingers. The tendons work like long ropes connecting the muscles of the forearm with the bones of the fingers and thumb. In the finger, the pulleys are a series of rings that form a tunnel through which the tendons must glide, much like the guides on a fishing rod through which the line (or tendon) must pass. These pulleys hold the tendons close against the bone. The tendons and the tunnel have a slick lining that allows easy gliding of the tendon through the pulleys (see Figure 1). Trigger finger/thumb occurs when the pulley at the base of the finger becomes too thick and constricting around the tendon, making it hard for the tendon to move freely through the pulley. Sometimes the tendon develops a nodule (knot) or swelling of its lining. Because of the increased resistance to the gliding of the tendon through the pulley, one may feel pain, popping, or a catching feeling in the finger or thumb (see Figure 2). When the tendon catches, it produces irritation and more swelling. This causes a vicious cycle of triggering, irritation, and swelling. Sometimes the finger becomes stuck or locked, and is hard to straighten or bend.…

    Laser Tag Research Paper

    By definition, laser tag is a team or individual activity where players attempt to score points by tagging targets, typically with a handheld infrared emitting targeting device. In indoor play, a visible laser combined with theatrical fog typically provide the visual effect of firing, while having no actual role in transmitting the fire signal. Laser tag is popular with a wide range of ages. When compared to paintball, people like laser tag better because it is painless and does not use any physical projectiles. Indoor versions of laser tag may be considered less physically demanding because most indoor venues prohibit running or roughhousing. Now whether the venue follows their own…

    Barbed Wire

    Joseph Glidden was born January 18, 1813 in Claredon, New York. He moved with his wife and two sons to Illinois. Soon after, his sons and wife died. He then remarried to Lucinda Warre who had farmland. Through his life, Joseph Glidden had many jobs within the government and teaching. In 1873, Joseph Glidden attended the county fair in DeKalb, Illinois. He saw a wooden rail with nails sticking out and decided to use this to start his design of barbed wire. His wife’s garden needed protection and that started his invention process. One year later in 1874, the barbed wire fence was patented. Glidden became a millionaire with assets. His company, with partner Issac Ellwood, The Barb Fence Company made 10,000 pounds of barbed wire the first year and 600,000 pounds by 1875. When Glidden died, he was one of the richest people in America. Although he wasn’t the first person to create the idea, he patented it, made it affordable, and made it a successful business.…

    dog tags

    Dog tags are required components of the military uniform. Dog tags are used to show a service member's name, social security number, blood type, and religious preference in case the service member becomes a casualty. Army Regulation 670-1 states that every service member must wear I.D tags at all times when traveling or overseas, even in civilian clothing, and that every service member in uniform must wear them in their everyday duty uniform. The importance and purpose of dog tags can be dated back to 1870 in the Franco-Prussian war. The Prussians issued them to their soldiers for the sake of identification; they got the nickname dog tag because dogs were issued matching tags in Prussian cities. The tags we use today originated in World War 1, and the purpose was that soldiers feared dying and being forgotten, so they created aluminum tags two of them, one to be taken when the soldier dies and the other to be left with the body, for easy identification.The importance of dog tags and origin, though, are two entirely different things. We have dog tags with just enough of our personal information necessary to identify an unidentifiable body. Even after one hundred years, our military uses dog tags for the same reason, identification.When a soldier dies, he or she buried with his or her dog tag around his or her neck so that even many years later that body will be identified…

    There’s a pause and every eye, that holds what feels like a laser beam, penetrates my entire being. Imagining throwing my freshly bought food into this rank garbage can, makes every part of me twist; I’d rather throw my coffee into this teacher’s face, but holding myself back from what is so tempting, I bite my lip, shed a tear and unwilling force myself to submit to this irritating and unnecessary suggestion. Waste of money, waste of time. Teacher’s like this have a cold-stone heart, if any heart at all and need to find a new time and place to take out their personal life on something else.…

    For years law enforcement has been searching for more effective less lethal options to apprehend suspects. One of the newest technologies available is the Taser, also known by industry standards as an electronic controlled device (ECD). The Taser uses electricity to override the central nervous system, an effect referred to as “neuro-muscular incapacitation (NMI), to cause temporary incapacitation to allow officers to gain control of a subject.…
