I will not consider bids higher than $60.
Need a frequency detector designed to work with inexpensive parts from electronics suppliers in USA.
Source the proper cheap antennas to see all the frequencies I want.
It must work with a laptop computer.
The detector must work using multiple receiving antennas to increase receiver strength and accuracy.
It must have multiple receiving antennas.
Need 3d Software to run on laptop to map the frequency detection generation areas.
Must be able to map as many frequencies at the same time as I want.
Must allow me to enter in the frequencies to map.
Must map frequency location, distance, depth, height, and strength.
Must work with as many receiving antennas as I want.
Must allow me to save results.
Must be able to use photo/video overlay to show frequency areas.
You also have the option to redesign it if you have a better design, just as long as it works the way I need it to work, as long as it is cheap to build.
And make sure everything is designed and works they way I need it to work.
I will provide details to successful bidder that I choose for my project.
Existing Software, systems, and parts can be used as long as it will do what I need, and be inexpensive.
This does not need to all be hand designed from the ground up.
