We’ve all been there. You’re sitting at a pink gentle, ready. Waiting. Waiting.

You start mentally writing your will, ready for hunger to set in, when an ambulance creeps up in your rear-view mirror.
Suddenly, the sunshine is inexperienced. The ambulance, by its very arrival, surprised your immutable site visitors gentle into permitting protected passage to your lane of journey. “How did it do that,” you surprise, “and how can I do the same?” As it seems, the reply is refreshingly easy — and deeply unlawful.
The form people over at The Drive turned us on to the exploits of Peter Fairlie, a hacker and tinkerer on YouTube. Fairlie’s finished numerous tasks involving the Flipper Zero, a kind of Swiss Army knife for digital experimentation — RFID, infrared, radio transmission; you identify it, the Flipper can do it.
But the Flipper, by itself, can’t management a site visitors gentle. Rather than radio waves, emergency automobiles use gentle to speak with site visitors lights — infrared lights, with sufficient luminance to chop by means of even the sunniest of days whereas remaining unseen by the human eye. The Flipper’s infrared LED is highly effective sufficient to manage close by units, however Fairlie realized {that a} site visitors gentle would require way more.
So, Fairlie wired within the infrared LED array from a safety digicam. He knew what flash frequencies the site visitors lights close to him would search for — 10, 12, and 14 Hz — so he set the Flipper to generate that frequency and despatched it out over GPIO pins. With the extra highly effective infrared array biking on the correct price, Fairlie had constructed a DIY emergency car transmitter — he may snap his fingers and switch pink lights inexperienced.
