Oscillator update

The prototype Oscillator is complete. The resulting frequency is around 3 kHz, and required some trial and error to output a relatively clean sine wave. Figure 1 shows the final oscillator design, and figure 2 shows the resulting waveform. There is still some distortion as the oscillator reaches the upper rail voltage of the op amp, but it shouldn't affect the rest of the detector system.

Output Signal

In yesterday's update, I mentioned that I would be re-coiling the transmitting coil to boost the output signal of the metal detector. I re-coiled it and found that the change in strength was pretty much non-existent, and after a few experiments I found that the operational amplifier I am using in the Wein-Bridge oscillator is the culprit. The output current is limited to around 50 mA, which doesn't supply enough power to operate the metal detector beyond very close range. I have ordered some new op amps ( OPA 548)  which have a maximum output current of 3A. This should be more than enough to power the oscillator. The new components should arrive early next week.

Pre-Finals Update

Image
Now that our capstone projects have finished up, we have found some more time to work on the metal detector. The prototype coil isn't going to be sufficient for testing the circuits on because it has a different inductance than the final coil, so our current priority is building the final coil.  We modeled the coil housing in SolidWorks and will be 3D printing the final design. Figure 1 shows a model of what the coil housing will look like. Figure 1: Model of Coil Housing The receiver coil will be wound around the inner cylinder and the transmitter coil will be wound around the outer surface. The inner cylinder and outer cylinder have a 4 cm and 8 cm diameter, respectively. We do have to keep in mind that this housing will be mounted on some sort of detector shaft. To speed things up, we will be working on building the oscillator while the coil housing is being printed. The oscillator works independently of the coils so we have the option of building and testing it...

New Coil Model

Image
After sitting down with someone who has a bit more CAD experience, we were able to come up with a better model for the detector coil. It features concave surfaces to ensure that the coils don't move around too much after coiling. It also has holes for the wires to go through to enhance the stability of the coil. The new model can be seen in figure 1.   Figure 1: New Coil Model
