Juha was in his perfect mode of innovation. An empty office. He could listen on to the relays, which would make a small clacking sound, if he moved. Infrared controlled lights in the building. He could hold still as many minutes as the sensor needed, in order for it to think there was no one present anymore. Ordinary people couldn’t do this. In fact, they didn’t know how IR-controlled lights work. Juha knew the details down to a PCB’s optimal SMB placement level. Juha – TechnoWhiz.
