a friend of mine is looking for a weller 12 volt soldering iron and the serch hasnt turned up anything. if any one knows where to order on it would be a big help. 73 kb9yet

Unless I'm mistaken (I'm still learning here), the rails are the maximum and minimum voltages the amplifier can go to. Whether it's single ended or double ended (one transistor, or two doing push

What does "rails" mean? For example: "5V at the rails" "rail to rail amplifiers" "As for current delivery, most will do a few milli-amps, but typically not near the rails" "an opamp with a

Yes you must use the resistor having the same color codes but you must be aware of the power passing over the resistor. I think you must choose a power resistor which can be used at high watts,

Check it out... http://www3.ncsu.edu/ECE480/ I also put it in the "Bookmarks" section of egroups/Electronics_101 along w/ another link. Dan - you might want to stick your circuit page over there

the resistor should have a set of bands in a color pattern on it, just get one that matches that color pattern and replace. Joshua ---- "A meow massages the heart." Pulse 8 -

i have a black and decker 12v cordless drill and a resistor burnt out in the charger and i need to know what kind of resistor is needed. if anyone knows what i need please get back to me.

Hello everyone, I have created a website, called the Public Electronics Circuit Archive, where people can submit their own electronics circuits, designs and ideas for others to look at, build,

Hi Thomas, have been using EAGLE 4.01 light for quite some time. It is excellent, with extensive symbol libraries, together with DRAFTCAD from "http://www.illuminated.com.au", [not available in lighy

Thanks for the information. They are also in the Radio Shack catalogue (I didn't think of looking until you posted your message). They might even have them at their web site (which

Where can I get BoardMaker? I found software from http://www.cadsoft.de/http://www.cadsoftusa.com that has a program called Eagle CAD. It was free for/to hobbiest. Have you heard about/know anything

Dear Thomas, You can use BOARDMAKER Program to convert schematics to a circuit board. You must modify the board because it doesn't work properly and can't give the right answer. But it can give a

So I'll just get right into it. I'm currently on transistor amplifiers. We haven't gotten to push-pull stuff yet, or any IC opamp stuff, so I'm sure my questions will be answered in class later.

Hi, I just joined this group. I was actually thinking of starting my own, but I found this one. I'm taking electronics classes and learning a lot, but have found very little tutorial information

I'm glad to see some people joining and using the group. As you can see, things arn't exactly super busy yet, but spread the word, I'm sure we can get some discusion going, and thats what it's all

Is there software that can convert schematics to a circuit board design? I have some schematics that I want to see if I can make a circuit board from (perhaps to 'recreate' the device that schematics

Is there a book on schematic symbols? I have schematics for a TI-99/4A and trying to create a circuit board using software from exprespcb (http://www.exprespcb.com [IIRC]).
