If the UK authorities adopted the same mindset and paid a visit to my spare room (aka 'workshop'), they'd find several Raspberry Bombs, Arduino-grenades and nano-grenades, ESP8266 IoT wifi remote detonators, antistatic bags full of I/O bombshields, trays of PIC Microbombs, Serial Flashbang RAM, 7-segment LED countdowntoarmageddon indicators, LCD bomb displays ('your bomb temperature is ...nDegC'), USB-Serial TTL bomb interfaces, a 1979 Acorn System 1 6502-trainer-cum-bomb, some old EPROMS (EBOMBS, more like, eh!), ultracapacitor detonators...
The other week, while browsing through a computer and electronics surplus warehouse (aka bomb factory), I even picked up what can only be described as a hardly-used Sinclair ZXeightybomb.
The dead giveaway is the storage drawers containg piezo sounders and LEDs, which I use to make sure that all of the IoT...er...bombs that I construct make a telltale bleeping sounds accompanied by blinkenlights to ensure that they can be easily spotted under vehicles and in the noisewheel compartments of passenger aircraft. Hell, I even have WIRE.
I'll get me coat and turn myself in right now.
