This point-of-purchase prototype never made it to production, but I’m still darn proud of it. I conceived it as an in-store promotional sign that would use motion sensor technology to light up and sizzle with sound as shoppers walked by.
I actually prototyped this sucker myself in Arduino with a PIR motion sensor. I copy/pasted open-source code and manipulated the light signal to pulse from orange to red. And then I bolted everything into a mini Weber Grill and presented it to our client for some surprise and delight in a stale status meeting. Cost and logistics prohibited us from manufacturing the concept, but the client loved the passion we showed for their business. So I’d call that a win.
