THE EDISON CELL
Rediscover the secrets of a 100 year old battery whose time may finally have come. With the wild fluctuations in fuel prices over the years, world concern over global warming, and simply the idea of creating new and more sustainable technologies, immense interest and progress continues in the world of battery development. Perhaps one day soon we'll have a battery that displays no "memory" effect; can be completely discharged or overcharged without harm; and require no complex computerized management system. This battery could even prove so durable it will be immune to damage from vibration and not break down chemically over time. In operation, such a battery might also routinely outlast the very vehicle or machine it was designed to operate in! Lastly, we could complete our wish list by adding in the impossible: low materials toxicity, simple construction, and, of course, good energy density. Does such a battery sound like too much to hope for? Thomas Edison didn't think so. |

TURN A BROKEN LAPTOP INTO A DIGITAL PICTURE FRAME Give an old laptop a new life by turning it into a digital photo gallery. As a techie, I have accumulated a lot of hardware over the years, and it pains me when I have to get rid of things that are old but still potentially useful. Such was the case with a laptop computer that had a broken hinge, broken Wi-Fi, and a broken sound system. It seemed destined for the scrap heap, even though it could still function as a portable computer. Because of my desire to recycle, I decided to give the laptop a second life inside a shadow box picture frame that I could hang on the wall. |

EXCELLENT CIRCUITS WITH EXCEL
Using spreadsheets to simulate digital circuits.
I recently read two articles about linear-feedback shift registers, which are shift registers with some of their outputs fed back to the input for generating cyclic redundancy check (CRC) bits or random numbers. Short of actually building these (and other digital) circuits, it's sometimes hard to check that they do what they claim to do. Here's an interesting and simple technique for simulating these circuits on a computer using a spreadsheet program like Excel. |
