Re: multiple conductors?
Beginner, If your wires are all insulated, then the current through each wire will vary directly with the wire diameter (inversely with resistance). The potential difference across the branch from supply to load will be the same across each of the individual conductors. In short the current will be ...

Re: ground chassis to neutral?
Gentlemen: Thank you for your answers. Here is what I understood: 1. Neutral to ground could get disconnected or opened somewhere along the circuit,therefore a redundant grounding conductor is necessary. 2. Neutral and hot could be wired incorrectly at locations (e.g., a light switch cut in on the n...

ground chassis to neutral?
Like many power tools, my 120V electric drill has a 3 wire connection: black is hot, white is neutral, bare copper is the "ground wire" for the chassis ground. My question is: Why not connect the chassis to the white neutral wire and eliminate the redundant "ground wire"?. The sa...

Re: robotics information
Emad, I am not even close to being a genius but you can't go wrong with building Boebot by Parallax as your start. It comes with a Basic Stamp II and all the stuff you need to build a robot. You can either use the chasis and drive that comes with it or build your own. It is very easy to program. Bes...

Re: Data Logger
Chris,
Is there a non-Apple near equivalent to the Ipod? Does the Ipaq do the same stuff or am I way off? I still use my old m125 Palm Pilot so I am way behind the times on all that stuff.

Circuit loading
Dear forum members: I built a square wave generator which over heated when I ran it through an amplifier and speaker. I solved the problem I think, but am now trying to get a better understanding of loads, overloads, impedance etc. Please read the two quizes I prepared below. I have answered my own ...

Re: DIY Punk Ethic and Culture
Philba,<p>Thank you for clearing that up! I like using wikipedia, it is free, but as you have pointed out so well, some of the entries could be B*llSh*t. I agree with your assessment.

Hi,<p>I've noticed that the expression "DIY" is starting to appear more and more on recent posts. <p>I looked it up on wikipedia where I learned that the expression is about the DIY (do it yourself) movement in the UK. Here are some excerpts from wikipedia:<p>"The DIY ethic is loosely...

Re: Radio Shack getting out of parts supply
Matt,<p>The books your talking about were written by Forrest Mimms and are still readily available. It would actually be a real loss if they weren't. The Radio Shack near my house still carries some of the books, reprints of the rest of them can be found at Fry's Electronics and at on-line bookstores.

Re: Radio Shack getting out of parts supply
I have been buying small electronic components from Radio Shack since I was a boy. I have many fond memories of going to Radio Shack with my dad to get electronics parts for robot projects and other neat stuff back in the early 1970's. <p>There are several very convenient Radio Shacks in my neighbor...

thielenm,<p>If you like Jolly Roger's idea about using IR,
here is a neat project that you can use
IR Remote<p>It is cheap and relatively small and you build it yourself. I bought this kit several months ago.
