It also handles the lower level playlist scheduling, reading of vector files, packing of the data for transmission, and streaming the packed data over a high-speed USB serial port. This Raspberry Pi board runs a multi-threaded Python/Tk application that handles the higher level Graphical User Interface to manage the laser show. The show-card is based around two main parts: A Raspberry Pi 3B quad core Linux single-board-computer, with 7вЂі touch screen (this is the brains behind it all вЂ“ the вЂshow controllerвЂ™ board) and a propeller micro-controller-based output board (spits the signals out to the real world вЂ“ the ILDA output card). To do this, I built my own custom show-controller, which is connected to the ILDA port of the projector.

Now, the harder bit! To keep the beam moving to form an image, the laser projector requires a continuous stream of X, Y & blanking analogue signals, updated in real time 25000 times a second. This means that the laser either вЂdrawsвЂ™ a visible line with the beam on, or an invisible вЂretrace lineвЂ™ to move between vector points with the beam switched off. This moves the beam, the safety inputs, and also the signalling that вЂbeam switchesвЂ™ (turns on and off) the red, green and blue lasers. This connector вЂbreaks outвЂ™ analogue signalling for controlling the projectorвЂ™s X and Y high-speed galvanometer-mirrors (galvos). The unit has an International Laser Display Association (ILDA) compliant 25-way D-connector interface on its rear. This is to counter the fact that the вЂspectral responseвЂ™ of the human eye is four times more sensitive to the green wavelength, compared to the red and blue. The 900mW is not split in equal proportions, and actually comprises of 400mW Red, 100mW Green, and 400mW Blue. We bought an off-the-shelf 900mW 25000 points-per-second RGB stage lighting laser projector. The laser show made its public appearance at our annual company summer party, Labfest, in August 2016, alongside an electronic test-your-strength machine and a robotic cocktail system.ДЇirst, the easiest bit вЂ“ the вЂlaser headвЂ™.

One such project is a full RGB (Red-Green-Blue) laser show, capable of displaying vector-based text, static images, and вЂvector-framesвЂ™ animated displays, for example an analogue clock, a bird with flapping wings, or a rotating LABMAN logo. At Labman, we also spend time developing personal projects with the companyвЂ™s support.
