Will do!

My knowledge of electronics is fairly limited, so I've been approaching this project with google in one hand and community help in the other. The information given about the diode stated it had a "working voltage" of 1.9-2.2 so I had assumed applying that potential across the pins would be...

I'll do that then. Thanks for all the help guys!

I wasn't entirely sure how to go about making the driving circuit, and I saw a lot of people using voltage regulating circuits to drive their diodes so I just went with that. It looks like I could convert my circuit relatively easily to regulate current instead of voltage.

I don't, the best I could find is the pinout posted in a review on the site I purchased it from which claims that the third pin isn't used. Lack of information seems to be the trend when buying cheap laser diodes.

Hmm alright, that's what I was afraid of. I can probably find something to replace one of my resistors with if I dig around enough, maybe it's about time I just order an assortment of some shiny new resistors. Thanks for the advice.

Hey everyone, this is semi-related to electrical engineering and a quick search didn't appear to turn anything up regarding this question specifically so I figured this is an appropriate place to ask this. I've bought this laser diode rated for 1.9 - 2.2 volts for a project I'm working on. I've...

Perhaps we found attractive and repulsive forces a bit more intuitive due to it being something we were taught at a much younger age, as opposed to cross products not being introduced until freshman physics. At any rate, this certainly helped me redefine my question so that google may be of more...

So, correct me if I'm misinterpreting your response, this becomes a question of how a force is exerted on a particle in a generalized sense?

I suppose that the force being subject to a cross product is what sparked his curiosity revolving specifically around charged particles in magnetic fields. You're right though, that is another question that came to mind and made an appearance in our conversation. Perhaps I need to work on asking...

Ah ok, that explains why I wasn't really able to find anything regarding the interaction beyond the resulting forces we observe. Thank you for the quick reply!

Hi everyone, I was talking to a friend of mine today who's studying electrical engineering and he essentially asked me why a charged particle feels a force when moving through a magnetic field. I thought about it for a moment, and realized I didn't have a good answer for him. Would anyone be...

Hey everyone, just introducing myself here. My name's Travis and I'm an astrophysics student at the University of Minnesota. If all goes well I should have my degree in about a year! Cheers, Ravenous Travis
