The Linux laser project aims to create a powerful, connected and scalable lasershow projector.<\/span>
\nThe goal is to lower the cost, like any hardware running Linux.<\/span>
\nA person known to Laserist community asked me “Why using Linux? While everyone is only<\/strong> using microcontrollers”<\/span>
\nThe answer is that Linux is used in many companies and even when you access your bank accounts there is a good chance it will work under RedHat Linux. Do you know that 75% of the supercomputers run Linux?<\/span>
\nClusters also run on Linux (like the Google search engine) and many other uses of everyday life…<\/span><\/p>\n

So it’s reliable.<\/span><\/p>\n

But the fact of using a SOC (system on chip) in 2020 allows to have a lot of power.<\/span>
\nIf we are talking about a connected system, we must be able to secure the data that is transferred over the network, for this it is transferred using a secure protocol using TCP \/ IP<\/span>
\nAlso, who nowadays would like to have an HMI interface with simple gameboy style graphics?<\/span>
\nIt needs graphic power to display screens, statistics graphs (etc.) and animate everything.
\nthe software uses fast multi-task C ++ code. In addition, the code uses 4 hierarchy levels (software architecture) to manage up to 3 lasershow projectors (currently)
\n<\/span><\/p>\n

The project was first developed with traditional electronics because I needed to be able to easily change the values of the components to make the prototype (click for link)<\/a><\/span><\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

Now the project is in industrial electronics (SMD)<\/span><\/p>\n

Special work has been done on the analog part.<\/span>
\nIndeed a specific power supply and an analog ground allow to have better results.<\/span><\/p>\n

Here are the tests for the SPEC REV6 (click for demo video)<\/a><\/span> of the electronic card they respond well to current standards:\"\"<\/a><\/span><\/p>\n

The latest hardware uses a new level adjustment chip.<\/span><\/div>\n
This is 2 times more precise (0.5%) and faster.<\/span><\/div>\n
\n

The software update is now done with Load \/ Save buttons.<\/span><\/p>\n

\"\"<\/a>Dark colors balance.<\/span><\/p>\n<\/div>\n

\"\"<\/a>\u00a0 Stunning laser effects.<\/span><\/span>\"\"<\/a>New statistics module show the regulated beam table temperature.<\/span><\/p>\n

(automatic backups and scales)<\/span>
\n\"\"<\/a>Hardware at Raspberry HAT standard \"\"<\/a> New daughter board with all the dedicated wires (AWG20) makes it iron soldering useless.\"\"<\/a>ILDA test frame (sorry for poor picture, i have to update it)<\/span><\/p>\n
