As I understand it he did finish it but came up against the limits of his testing equipment. He has since switched to the more accepted magnetron powered version. The magnetron he is attempting to use is from a microwave oven and suffers from "thermal runaway" and he resorted in his last...

The simplest explanation is it is a type of "Radiation Pressure" that is higher on one end of the cavity than the other. https://en.wikipedia.org/wiki/Radiation_pressure This is a diagram of a proposed "Optical Em_Drive" Note the lasers are at the same angle as the sides of the frustum...

My goal isn't to even get thrust. (What everyone else seems to be gunning for) NASA did one test and showed a distortion of the laser of 40x what ambient air (or heat from the test article) could account for. My goal is to develop a version specifically to warp spacetime as much as possible or...

Accelerating Universe: Not As Fast? A UA-led team of astronomers found that the type of supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before. The findings have implications for our understanding of how fast the universe has been...

Better? What say you guys on the possibility of this being a usable HeNe? Stabilized HeNe Laser Kit with Parts to build Arduino Compatible Controller The next step up is in the expected 2K+ range but I assume is much closer to "NASA" quality. SIOS SL02/1 Compact Self-Contained Stabilized...

Here are a couple of setups from NASA I (eventually) want to emulate and even surpass. I'm trying to learn the fundamentals before I put down big bucks on better equipment than NASA is using. So far the obvious component that never changes is the use of a He-Ne laser. If it looks like a...

I want to build a Fabry–Pérot interferometer in order to study and understand the equipment and technology. Fabry–Pérot interferometer Wiki It is also an excuse to buy my first "Lab Laser". I intend to use this device to attempt to measure gravity. (proximity or even orientation to a large...

Well my idea of "exploiting" the market would be doing a detailed build thread and pointing potential buyers to it as a form of advertising. I have no interest in taking $ for something I can't ship to a customer the next day. Besides, that is a ways off. I have at least one personal build to...

I have several friends very interested in this build. I will likely be doing more. A TNG phaser build might not be far off. Or a Klingon Disruptor. There seems to be a corner of the market for Star Trek builds that not many people are working on.

Alright guys, calm down. This is indeed "just" the host... So far. I am a complete noob to building laser devises and figured that posting the project early would be a good way to get advice and feedback. I am planning on using a 20mm or larger module (depends on the internal dimensions of the...

WOOO HOOO SUCCESS!!! I HAVE GOTTEN MY WAND PHASER APART WITHOUT DAMAGING IT!!! Alright I got it apart. The first step is to remove the "cooling fins" I used a pair of taped pliers to prevent marring and pulled firmly with just a little wiggle. Be careful to grip it about 2/3 back because the...

I was certified on "electronic warfare" equipment during my time in the .mil. That high power RF is no joke, some military hardware is a hazard from under 5ft away even fully intact. This is an issue when your supposed to have someone on a gun on top of the vehicle and the RF device has to be...

I think we need some driver tutorials in the "Tutorials, Help & Repairs" section, I'd like to wright them myself, but I have to figure out how to build the drivers first...

I really like Hiemals drives, I'll ask for his OK/Help in duplicating them. What do I need to be able to test the drivers and make sure they work like they should? All I really have for electrical testing is a multimeter.

Thanks red, and this is right where I'm at. I just can't wait to make solder fly and so I'm here... Hoping for a shortcut that will also lead to me making a step by step thread.

If it is a low current switch, it and the chip, would just fry right? Is there a way to determine this? I do have a multimeter. I wouldn't mind the challenge of modding the chip if I can determine exactly how to do it. Turning it into a proper driver would be great but I thought to keep it...

A - My soldering skills are basic, I've watched the "101" and searched (using the google bar) to see what advice I could find, I was left with (strip everything) or stuff specific to particular hosts. B - Of all the info I'm learning the drivers/boards/circuits are the most complicated. I...

I also have a 445nm version of this laser a "G303" in my sig. Mine has a halo defect (looks like a ring with the spot the diamond) but it burns (I use it to trim dead leaves from house plants). For the cost it can't be beat. Also, if you still have the dead host I would take it apart for...

I forget that higher mAh normally means more resistance. Here are the Batteries I'm looking at. I'll look at some 700mAh. 2x Efest 14500 800mAh Here is the host, I have one in hand (I can answer any questions) and I'm going to start a thread where I ask what parts to strip from the board. It...

Sweet. I was hoping I could get 1.5a to push a NDG7475 1 watt. (I want to build a matched set of 1 Watt Red, Blue, Green, Violet at some point) I have found a tidy side fire flashlight that will fit a 20x25mm pill. Would there be anything I could do with a pair of 14250s that I couldn't...
