You sound like a parts hoarder like me. lol! Im bad!!!
I'm sure you already know this but you can buy a TECs dirt cheap on Amazon or eBay. This is just the ceramic junction itself, no driver, heatsink and or fan.
Years ago I bought a dozen just to play with, cost was like $30. They worked for a bit but eventually burned them all up, didn't know they had to be current regulated. Lol!
Unfortunately i can't answer your question. I'd consider myself nothing but a beginner. And i know little about TTL.What is the meaning of TTL slot on this driver? If I do not have 5V but apply 10V there - what happens?
Does anyone know solderless plugs which could fit to the contacts (diameter ca. 0.4mm) of these butterfly arrays?
TTL control is a quick-n-easy way to switch the laser on and off quickly. Very handy for CNC use. In a projector setting this diode is more likely to be used in this control can be used for interlocking the laser, shutting it off if the case is opened as a safety measure.Unfortunately i can't answer your question. I'd consider myself nothing but a beginner. And i know little about TTL.
As a temporary solution, perhaps you can just solder the TTL control wire directly to the TTL socket.
I understand a fair bit of chinese, and according to what the description says
" 0V is off and 5V is on, the frequency of input will dictate the pulsing frequency of the laser. "
Honestly i don't quite understand the need for TTL, isn't it just another way to control the brightness of the laser using PWM switching?
Why do we need TTL if we can adjust the current output by turning the potentiometer?
Anyone else with the right knowledge, please feel free to chime in.
