littleBits o18 IR Transmitter

My kid figured out in about two minutes that pressing the button bit makes the IR transmitter fire a pulse across the room to trip the AC switch, and now the whole hallway light setup is his. The little pulse window is tiny but it reaches way further than I expected. Honestly the most satisfying bit

Paired this with a button bit and it fires my AC switch from across the room every time. The trigger response is basically instant, which surprised me for something this small.
