Tell us about yourself!
if you have a nice quiet place, how about using an oscilloscope to monitor the amplified mic. A properly calibrated scope should give you the accuracy you need.
Sorry the reply took so long. what I found is simple thermometer. It came however from Human Systems Measurement located in West Yellowstone Montana. I guess the bio-feedback device was too expensive to let me keep:))
Neat project. Years ago I had a little device that was a little larger than a flash drive that would warn me when clenching my teeth. It used a single electrode patch that I would stick on my cheek. Worked well, but it certainly didn't have the bells and whistles that your device has. My device didn't have any storage to save data. It would just beep at me when it detected electrical energy from clenching muscles. It was great for basic biofeedback.
Now, it would only wind my ol' pocket watch :)))
anybody know where you can download the Delorme Earthmate Serial Port Emulator, or does anybody have a copy the can post??? All links now go to the Garmin site and I haven't been able to find in on there anywhere. Is there a version that works on win 7???
Great project ! ! ! Great layout ! ! !How does it sound ???Perhaps a better schematic layout would be helpful.
how about a schematic ???
The ground wire from the pipe clamp to the ground rod should probably #6. This is same guage that utilities use to ground CATV, Telco and others to a ground rod at the base of the utility pole.
How can the capacitance range be expanded upwards??hoke
why didn't I think of that ????? :))))
