Do airgun mfgs measure this kind of thing? I feel like hammer bounce prevention should be built into PCPs.
I use a PC based Velleman PCSU200 that I bought about 10 years ago when I was doing my original electronic air gun control design. Its basically a little box 4x4x1 that plugs into the usb on your laptop, and has 2 sets of leads with clips on the ends to measure various voltages. The o-scope is just a fancy voltmeter that can read a wide range of voltages, and has an adjustable time scale, a memory, and with this one, 2 channels.... There are other cheaper equivalents to the Velleman out there if you look. To do what I have produced so far, I needed a pressure transducer (that I had already), the Velleman, a laptop, a few wires and jumpers, a 1.5k resistor, and a few batteries. The mechanical part is the most difficult, i.e., getting sensors to function reliably. The wiring connections and figuring the correct buttons on the display, are kind of hit or miss, but you get there eventually.
Boy, it's about time Lloyd does something beside spoil those darn grandkids!!! Thanks Lloyd, and I hope you're having fun!!!! I miss seeing you at the fun shoots.
OK, I thought Lloyd was trying to determine the slope of the pressure rise curve.It is all good, I appreciate his work.

I look forward to seeing what effect pellet calibre, weight and release pressure have on the pressure.
