Hi! So, I had wanted to build a working example of the double-slit experiment. Yes, I suppose that diffraction and the wave nature of light is easy enough to demonstrate, but it's always better when you use lasers, am I right? But even beyond a simple double slit experiment, I found this article...

Has anyone attempted a build with the (expensive) IR filtered modules? They seem to be larger than the standard modules... And if someone has, what kind of host did you place it in? I apologize if this question has been asked before... I tried searching for something of this nature, but I...

Sorry for this noob question. I understand that normal rectifier diodes (i.e. 1N4001) have a forward voltage drop of about 0.7 V. And when connected in series, the drops in voltage should just add up, correct? Well, I've got two 3.0 V Soshine CR123A's (which are incredibly overcharged...

Okay, so, this has been bugging me for a while. Whenever I'm discussing anything electronics-related with my friends, we inevitably come across the topic of batteries, and when asked which type I have in a flashlight or something, I just say the first thing that comes to mind. But then I wonder...

Hey guys, I've been doing a little research and I decided it was time to attempt at a laser build. I'm going to use the DX 4171 host (I'm assuming it's the new model, since I just ordered it), and I was going to use a PHR-803T diode. What I can't decide is to use a FlexDrive or rkcstr driver. I...
