Alright,
I am working on building a 445nm 2w blue laser driver
I have some questions about some of the items i have purchased.
The laser diode i'm using from DTR's laser shop
http://www.amazon.com/445nm-Diode-Co...ilpage_o03_s00
The plan is to make a constant current linear driver using these parts:
RCL12251R47FKEG Vishay / Draloric | Mouser
--1.47ohm resistor 2W power dissipation (going to be in parallel to get the desired .735ohm resistance I'm looking for (i think))--
TEXAS INSTRUMENTS LM1085IT-ADJ/NOPB IC, ADJ LDO REG, 1.2V TO 15V, 3A, TO-220 (1 piece): Rf Transistors: Amazon.com: Industrial & Scientific
--The voltage regulator (LM1085)--
http://www.amazon.com/gp/product/B01...A3RD7YW5IJU8WP
--The power supply 7.4v 400mAh (going to hook 4 of them up in parallel to get the desired 1.6A (i think))--
Now of course i'm going to be adding capacitors to the circuit as well but have yet to figure out that part. I also have a heat sink for the diode and heat sink for the LM1085 and a small computer fan.
My desired output to go into the laser diode is 4.6V and 1.6A
Now for my questions
Is the power source i chose viable?
Will the resistor i chose work? (if so how would i go about soldering that?) first time using a resistor that does not have pins.
Am i going about this correctly?
