I guess my thoughts are that i have 8 deep cycle batteries just sitting around that i could be useing for something. My wife and I have a small hobby farm with about 80 acres in north central Minnesota. I was thinking of maybe useing them to power greenhouses or the heater in the shop in the winter....

I have been pondering buying some solor cells for various projects. After alot of searching and finding the cheapest is about $4/watt I wonder, can they be built at home cheaper? Does anyone have any experiance in this?

You would do better by replacing that Chicago Electric motor with something like Dayton. You'll pay a little more now for it but it will last 10X longer. I swear they have small horses in china .

I'm wondering, did the old motor by chance have a start capacitor on it that just went bad?

I have a vampire model 4040 car alarm which i have been trying to get to work. It was working ok then for some reason it keeps trying to run through the start engine cycle (relays toggle on and off for about 45 seconds and the LED stays lit up solid). I can't get into the programing to reset everyth...

I would bet it's the motor capacitor.

thanks all. Edd the noise is in AM, FM as well as cd playing. It sounds like it comes from all 4 channels from the amp. I will try a few things you all suggested and see where that leads.

it still all boils down to the old rule. You can only convert it, not make it or destroy it. But you gotta love it none the less. :p

the pitch changes with the rpm's of the engine. It did not make this noise till i replaced an amp and added a passive crossover. I'm pretty sure it's picking up through the crossover but even teh filter i picked up at radio shack did not get rid of it. If it helps, when the lights are on or the air ...

I need to make a filter. My problem is i am picking up spark plug noise in my radio. I have a few large capacitors. What else would i need to make a filter? i think the capacitors are 9700 mfd. I purchased a filter for this and it did not work for some reason. Thanks for any help.

forgot to mention that i am trying to build a cnc wood router.

Thanks Don, that clears a little of the air. I did find two boards from an old optocopy camera my company was going to throw in the trash. The board is at MicroKinetics.com . Would these be overkill?

Ok let me try another question. How would one match a servo motor to a gecko driver G320 board? Thanks! Gecko Website

Hey Mike,
I just ran across this page while looking up info for my CNC router stuff. Stepper Info here!

I think it was well worth the price. Although i must admit i got it from Barnes and Noble for a lot less. For someone who knows nothing about building a CNC router i think this would help alot. Here are the contents by chapter: 1 Design 2 Electronics 3 Making a printed circuit board 4 Driver assembl...

I'm working on a CNC router and need info on servo's and steppers. I have the CNC robotics book by Geoff Williams, But is there a book on the advantages of each? Disadvantages? Wiring diagrams?
