    Adding a simple laser pointer to an existing project of mine...

    Well, the whole point of doing this is to have a laser built into the box that shines straight down. It has to be so simple that either a 9 year old or a 70 year old person can do it without much effort... As far as the laser module, I am going to use one very similar to the one you linked...

    Adding a simple laser pointer to an existing project of mine...

    Well, I decided to go with the other laser module. THIS one. Also going with a 12 volt PS with at least 1.5A to power it all. I may have to use different capacitors or resistors for the 3v output for the laser, depending on how it goes with my test breadboards, but here is my design... Here...

    Adding a simple laser pointer to an existing project of mine...

    Yes, my last generator was based off this same schematic, but I did it in a 1 gallon jar, with one 6 inch rod going straight down the center, and about 2 feet of silver wire wrapped in a large coil around the outside edge of the jar. The distance between the center rod and the outside coil was...

    Adding a simple laser pointer to an existing project of mine...

    Using 2 silver rods about 6 inches long in a standard wide mouth mason jar. The rods will only be about 1 inch apart. I'm wanting it to make around a 20ppm solution overnight. The Laser would only be used when you push the button to see how fine the "line" shines through the silver water. So...

    Adding a simple laser pointer to an existing project of mine...

    Must also keep in mind that the same 9v power supply is feeding the CS Generator Circuit... It is based off of the schematic pictured below, only there is a 1k ohm resistor on the output to the anode instead of a 75 ohm, and there is no meter,and Im using a 9v power supply instead of the...

    Adding a simple laser pointer to an existing project of mine...

    THIS is the diode I am wanting to use... But I have to build a driver for it. Its a LiteOn #LTLD505T laser diode. There is a spec sheet available on the page I linked too... With the way I am designing this box, it would be easier for me to add the diode and the driver circuit on the same...

    Adding a simple laser pointer to an existing project of mine...

    Maybe Id be better off just buying a couple of these and add a buck converter in my box to drop the power from 9v to 3v. I get confused real easy... Im good at following directions though lol.

    Adding a simple laser pointer to an existing project of mine...

    Ok, I think I understand... but I am HORRIBLE with math lol. Can you please tell me what resistor to use? Provided that the laser diode is 5MW 650NM. Using the calculator from that link confuses me because I dont know what "milli-amps" this diode requires... All I know for sure is that it...

    Adding a simple laser pointer to an existing project of mine...

    When I click that link, it shows me a diagram with only the lm317 and 1 resistor for the output. Everywhere I read it says that I need a driver. But from the diagram in that link it does not have the 2 capacitors, or one of the other resistors. I need a power output between 2.4 and 2.6...

    Adding a simple laser pointer to an existing project of mine...

    The 650 is what I have available... And I have also been using a pen laser for years to shine through the jar. However, I want this setup to have a laser built into it, so all you have to do is push the button and a laser shines down in the jar, rather than looking through every junk drawer in...

    Adding a simple laser pointer to an existing project of mine...

    I am in the process of designing a new CS Pulse Generator Machine for the use of making colloidal silver. I already have the pulse generator design made, but am wanting to add a simple laser to the box for testing/viewing the PPM or "strength" of the colloidal silver being made. My input is a...
