You should know that there are a large number of tutorials online for ways to make a handheld EMP (electromagnetic pulse). They will disrupt electronic devices in your vicinity and would be very useful if masked men approach you and try to photograph you with a potentially illegal biometric collection application. If made correctly they are harmless to people, and if made incorrectly they are most likely harmful to the operator. It is a non-violent defense device.
So any mention of an actual tutorial? Link? Any information?
I thought the post was junk but it seems true https://hackaday.com/2016/10/12/become-very-unpopular-very-fast-with-this-diy-emp-generator/
Fun idea but it’s not powerful enough to do anything meaningful.
There are plenty of actually handheld ones powerful enough to disrupt small electronic devices like cell phones. Enough to make them fault and reboot.
Same thing that eventually happens in every What If? when more power is added
