Jokes aside, I've always been curious how much you could accomplish in this direction by driving a microwave magnetron into a horn antenna using an old pulse forming network off ebay... Hell, even travelling wave tubes are getting affordable these days.
a grill lighter or modified milty zerostat can easily inject faults, albeit more manually and less precision than one of these timed devices. but it's also an order of magnitude or two cheaper...
Modern plasma antennas are much more advanced than the traditional spark gaps.
I’ve built a rather complex robot with Nema steppers. Now something is messing with the control board and causing the CPU to glitch. Physically apart from the robot, the CPU board works fine for weeks. It also has a completely separate power circuit with optocouplers. So my guess is that it might be the power supply or one of the motors emitting electromagnetic interference. But how would I measure that?
So to me, it looks like the glitching happens exclusively inside the CPU. It appears that I’m randomly experiencing the exact same issue that the PicoEMP in the original article can induce.
1. Stepper and CPU use separate power supplies and are optically decoupled.
2. I’ve monitored min max voltage on the CPU caps and they are fine the entire time, even during glitches.
