If you're using a microcontroller, you can use multiple sensors in tandem. Say an object is registered 6 cm from proximity sensor A, and 4 cm from sensor B when the clash is triggered. Assuming...

There are numerous tutorials online. Two good ones are Erv's video tutorial on YouTube, and this one here. If you've got some old junk electronics, you can rip them apart to practice soldering and...

Though I haven't built my first yet, I've been thinking of different ways to join two hilts.

The most obvious way is with some kind of threaded coupler, but this isn't exactly quick-release. ...

Here's a possible idea. Those sites that sell robotics stuff on the web often have various sensors you can purchase, such as infrared proximity sensors. I'm not sure if the polycarbonate blades are...

I was actually looking at some attachment kinda like this, except it held your drill horizontally. The idea was to use it as a lathe, but on reading reviews, it sounded as wobbly as it looked.

On...

Looks pretty good, particularly for a second (I'm still working on my first, myself). I have a few questions, though. First, why did you put your retention screw as far away from the emitter end as...

I'm pretty new around here, but not in forums in general, and it seems to me like you're taking offense where none was intended. Just because someone doesn't agree with you and gives different...

I realize this thread hasn't been posted to in some time, but I figured I'd post this here because a) it's a sticky thread, and b) it might help some electronics newbies (such as myself).

I was...

Actually, if memory serves, that was Cyberdyne.

I don't think the main problem is with this Hyperdyne guy, though it certainly seems like he's part of it (particularly if he's making IP violation...

More or less, yes. It's a little finicky to get some of the buttons and stuff to align properly (plus some of these aren't available in the builder), but for the basic hilt parts, it's fine. You do...

As mentioned, sometimes language differences can make things a lot more confusing than they would normally be.
Generally, you drill a hole that is slightly smaller than the threads. You then use a...

It may be possible to use a 500mA micropuck and a 1000mA buckpuck. I'm not sure if the mixing of different outputs would cause a problem when wiring the pucks in parallel, but if it works, it would...

Another technique I was thinking of would be to wrap tape around the hilt, angled (picture a corkscrew or screw thread), and use the edge of the tape as a guide to score lines. Repeat as necessary,...

Somewhat related to supertrogdor's suggestion (in that it helps the viewer know the specifics of how the color and light level was produced) is my suggestion that posters specify how the LED is being...

I know that with some plastics, they use a bath in a chemical such as acetone to smooth out signs of grinding and such. I seem to recall seeing it on some TV show (if I recall correctly, it was...

Welcome to the forums, AardvarkSagus. I'm brand new here too, and I would agree with the recommendation to look into PVC sabres, for several reasons:


The materials are a lot cheaper. A metal...

Well, I haven't done a lot of research yet, but I am one of those people who learns by doing. I tend to consider what I want to do, plan out to the best of my ability (including trying to anticipate...

Hello, everyone. I'll try to keep this brief (I'm usually quite verbose), as I have to get up for work in less than four hours. :)

Anyways, I'm from Canada, eh, and I've long had a fascination...
