I would bet that David is the first to publish plans for a DIY Laser Beam Analyzer. “The laser beam spot is the tool in laser welding cutting. Industrial lasers are really great, but there’s a huge problem when it comes to knowing the state

Making of CoilOsapien - Robosapien Coil Gun

Remember the video we featured last week? Well the CoilOsapien (Robosapien Coil Gun) is done, look here for all of the details. “When the servo is activated it turns the disc inside the housing, with each spin it will pick up one BB and drop it into the firing chamber. The coilgun will need to be on a slight angle whilst reloading to allow the BB to roll to the
