I am working on a project where I have to pulse a laser against a spinning, six sided polygon mirror motor.

(worth noting that i have them from china)
I am pulsing at the motor frequency x6 to get a single laser dot...
I recently took up a rather ambitious project for my skill level as I have never worked with almost all involved components before.
I would be very grateful if you could help me find the best components to hopefully make this work.
What I am trying to achieve is this:
A laser beam is shining at...
Hey all, Hope you're all well.
I've been looking over the past few days for a specific type of IR Laser detector system I require for a design project underway.
To explain quickly what I need is basically a system (as small as possible) that can detect an IR laser (in multiple wavelengths)...
i have a laser keyboard and the projector inside it is really weak I can’t see anything unless i put it’s really close to the surface that’s it’s at which makes it impossible to use , the projector used to work fine and it still works but it isn’t strong enough for the eye to see.
Any help or...
Hi,
I came across a circuit which can be used to drive a laser diode in continuous mode (CW) or modulated (<=100Khz).
A BFR540 (NPN) transistor is used to drive the laser diode and a photodiode (inside the laser diode package) provides an output current based on the optical output power, which...
Does anyone know if a Ricoh Alficio Mp 301spf laser multifunction is worth salvaging or re-furbishing for sale? I found it on side of road. Was wondering what power cord it needed too if anyone knows
