Is anyone working on the use of the Raspberry Pi Camera module as a heart rate sensor?
I am new to using Raspberry Pi. I want to build a non-contact real-time heart rate monitoring system using Raspberry Pi 3 Model B and Pi NoIR camera.
I found two related projects which are...
I would like to make a metal detector strong enough to detect a piece of stainless steel tape in the cable that we make.
We make electronic/electric cable, for example, sometimes this cable is bad and from the 50,000 feet we make, we have to cut it 3 times (we call that splices)...
Thank you very much Brian, for your time and consideration.
The drawings was just an example. I need to make it activate with an RF signal 1- 3 feet away.
Accuracy is not important, just as long as it operates when the device is near it.
I dont mind the size of the wand, I can work around...
I want design this project for magic shows, and I would like to include this in the act.
How Can I design a circuit so I can make the ball move? I need to design circuit for it.
The wand will have the transmitter.
The ball will have the receiver in it.
I want to make it stop when the wand is...
I'm working on a simple short range AM radio transmitter , and I faced some problems which I hope to find solutions here :-)
1st Problem : I designed 1MHz wein bridge oscillator and it's Pspice model works like a charm . so what is the problem ?? :evil: ... the problem is that I was...
