Yeah, I have a few detectors, but do not really know all the details when it comes to good coil design. I am sure there are numerous factors that will help with depth issues. I was just wondering if anyone had any ideas. I have a house out in the desert and thought it would be fun to just run around...

I recently read an article in wired as well as seeing 'best places to find treasure....' or something like that where this guy towed a huge search coil for a metal detector behind him on a quad. Anyone have an idea on how I could make a large search coil, maybe 5x5 or so to tow behind my quad to loo...

I need a simple interface that will allow you to record 'routines' that control up to 4 low volt/low amperage devices through a serial port. I have some existing software that will give you an idea of what I am looking to do as well as a bunch of these controllers. I imagine you can use them for alm...

Thanks everyone for all the input. The old motor actually states that it is reversible on the plate by reversing the wires. But on this second motor, it does not state the same information. They are both from the same company, same HP, etc... <p>The old motor appears to be in better condition, but i...

The last motor I had on my table saw went bad and the industrial parts liquidators by my house only had 1 that rotates the opposite direction for what I need. It would be a major hassle to remount the motor, so I am trying to find out if I can rewire it to change the rotation from CCW to CW.<p>It is...

I would like to pay someone to send me a working example for a 7x7 matrix bar graph display. Each bar would respond to a different frequency with input through a mic. I would like to use ultra-brite LEDs for the project. Any advice would be greatly appreciated as well. Please contact me for more det...

I am trying to make an inexpensive sound to light modulator using LEDs. Anyone know of any kits, or how I can make this? I would like a 7x7 matrix. 49 LEDs... <p>Thanks!<p>Bryan

Thanks guys! I have tested a few of these in the past and they seem to work out fairly well in my larger project... What I am looking for now is to get the most torque with the smallest amount of room... <p>I need some type of small gear box so I can use some inexpensive hobby motors geared down to ...

I can't seem to find the time to do this myself, so I am looking for someone to help me build a device that will control up to 4 low amp motors with varying sequences. I would like a fairly simple way to select different pulsing patterns or select a 'random' way of going through the different sequen...

I need an inexpensive way to get about 1" - 2" of linear motion. I have a few ideas on how I can do this, but was hoping to find some inexpensive pre-made components with gear boxes or whatever. Would need to push/pull approximately 5 lbs of pressure. <p>I am currently using a cam driven s...
