I always mused that Maths is short for Mathematics. Just use the ESD-zapper gun, crank it’s voltage to around 15kV (thats a bit more than the standard asks, but usually what we test our devices with) and do air discharge on the vertical coupling plate or the reference plane below your device. I saw those on ebay a while back. ]:op, We’ve seen the chip whisperer so is this the chip shouter? This isn’t the home shopping network. It would make EMPs that actually ruined electronics,not reset them.
I’m not an engineer, but I am really good at following instructions.
A design like this, does a similar job, but repeatedly and at high frequency, so it can certainly disrupt normal operations if it gets close enough, but it’s not an EMP at that point, just electrical noise, you can get the same effect going close to an electric motor, even worse if it has a bad cap. Using emp jammer diagram of lakewood, with pools emp schematic emp slot machine jammer diagram casinos must await the reels.
Shoddy wiring, Chinese ebay HV generator and Li-Ion cells – that’s a recipe for a Darwin Awards takedown. Take it a step further – my MIG, TIG, stick AND plasma cutter are all very high power spark gaps! This project is not an EMP generator, it’s just a pretty weak and random EMI generator. Most Tig welding, save aluminium and magnesium, is done with DC. Part of the reason the magnetic field is strongest between the magnets is because the magnetic shielding shunts the other half of the dipole. You read a story on the Internet. Looks to me like a design that works by accident and not in the intended manor It would be interesting to see some measurements of peak E & M field strengths at some interesting distance to determine the effectiveness of the design. Funny he can build a little EMP generator but can’t properly bias an LED. This is bad mojo… using spark gaps have been outlawed in the US for almost 90 years now for good reason. Kinda disappointed he didn’t try this on a Galaxy Note 7.
A spark gap oscillator works by either the capacitor charging up, then discharging through the coil with the spark acting as a switch, or by dumping power into a capacitor/inductor circuit with again the spark gap acting as a switch.
well . That must sound wierd.
So – 1 MV. Who knows what frequencies the spark gap is emanating, but I’m sure is would at least jam someone’s Blue Tooth headphones from right beside them – until they notice the loud sound coming from the strange gadget in your hand. isnt a welder practically a spark gap? The spark gap he is referring to is used by the high frequency start circuit…it uses a low power high voltage arc to start the high power voltage welding arc.
It actually works on some slot machines. This device makes a 1cm spark, it’s more like 20kV.
It is not required in this application due to the heads only sensing sharply alternating fields, and the head coil amplifiers rejecting low frequency changes. Recognizing those cut-rate slots.
1×10^6 V? Ah, I hadn’t considered that. There is no other shielding except a quite close magnetic circuit made of steel.
