What does an engineer do when one of the Christmas decorations chews through batteries? Buy more batteries? Definitely not! S/he finds a more efficient solution. Our LED star ornament plugged directly into a 4.5V battery pack comprised of 3x AA batteries. There were no resistors or switching to reduce the current flow. As a result the batteries ran full pelt all the time and were nearly flat in around 24 hours. Plenty of room for improvement, I thought. I've replaced the original power supply with an Arduino Due, a 9V battery and a program that sleeps the entire microcontroller for 15ms then turns it back on again to flash the lights for 1ms. Persistence of vision means it appears not to flicker at all and the lights are still very bright. My back of the envelope calculations show that power draw is down from ~800mA to ~60mA resulting in an approximate 1200% efficiency gain. Even if we leave it on permanently, we would still save over £20 in batteries between now and New Year! I could still do better than this and break out the 555s and bread board but I feel like I've already smashed the ROI curve on this one.
