Hello,
Can you give me more details about the laser device?
I have many years of experience with Python application development and I'm also an experienced Linux user.
I have been using the Raspberry Pi for quite some time now and I've made various applications with it including home automation, video surveillance, media center add-ons. Among the hardware I've used with it are EnOcean devices, GrovePi sensors, HAT boards (GrovePi, SenseHAT, UnicornHAT, PiFace relay), picamera, magnetic card readers, Modbus devices, servo motors and many others.
Best wishes,
iticus
