Its a good idea to protect your investment in a dvd burner diode by hooking it up properly.
Diy laser driver.
Constant current is just what it states a constant output level over time say 30 ma in theory forever if needed.
The potentiometer 10k and resistor are used as the voltage limiting circuit connected with the adjustable pin1.
Software for laser cutting engraving.
At a very general level there are a few classes or types of laser drivers which you will hear commonly discussed.
The second type is more easy to design and us.
For the driving of the laser diodes ld special drivers circuits are used.
They can work in two ways.
As battery start giving supply it first flow through the ceramic capacitor 0 1uf.
Useful software for lasers and laser engraving cutting machines.
2 produce constant current driven through the ld load.
