Hello everybody,
I have a nugm02 diode, and I want to make a circuit for it, but I don't really know how. if I use a 9v battery (or power supply), and I want to put 4,86v at 2A into the laser what kind of resistor do I need? Because I am very confused...
Thanks for helping😁
hello everyone,
two of my lasers don't work for the same unknown reason, its something with the batterys but i do not know what, because both the battery's make contact to eachother, to the spring for + and to the switch for -. they are fully charged and the host fully works as well because...
Hello everyone, I ordered some parts from DTR a month ago, and normally it would take 10-15 days to get to my house in the Netherlands. But it's a month later now and it still hasn't even been to a USPS facility, so does anyone know if this is only a problem that I have, or does somebody have...
hello everyone on the forum,
i just bought all the parts to make a NUBM44-v2 (with the money that i earned myself) which is obviously very expansive, when i told my parents they got mad at me because its so expensive, so does anyone have good arguments which i can tell my parents in order to...
okay, so i broke my driver from survival lasers and i wanted to make a blank circuit board so that i can hook it up to another driver that feeds my laser diode
but i didn't know if i did it right like this.
so can anyone tell me if i did, because i dont want another broken laser diode...
Okay...
Hello everyone, does anyone know a site where i can find a lot of Data sheets.
I don't know if such a site exists but if it does it is far easier to have all the datasheets at ones in stead of finding them one by one.
If you are wondering why i am asking this it is because i want to fill a map...
Hi everyone, im a newbie with lasers
i was making my first laser and i failed, can someone pls explain to me what i did wrong.
the things that i used were:
No-Diode Host Bundle from survival lasers
G-2 Lens Assembly from Survival lasers
Two Ultrafire RCR123A batterys
M140 M-Type 2W 445Nm
and an...
Hello everyone,
i'm new here and wanted to ask a question about making the same laser as styropyro in this video:
but i don't know how he powers 3 different drivers with one power supply, can anyone help me with this?
(this is my first post, and i hope to post a lot more and to learn many...
