Even though the Halloween is already passed by, but it’s always fun to create a new open source project, especially when you do it with your family!

If you’re bored with the ordinary scanner, maybe this Jack-O’-lantern, “Larson Scanner” is going to light up your boring life.

For your information, the Larson scanner is named in honor of Glen A. Larson, the man who is responsible for making both the original Battlestar Galactica and Knight Rider TV shows (Sounds familiar to you, isn’t it?)

The Larson Scanner Kit

Have a detail look on the Larson Scanner. It’s based on the ATtiny2313 microcontroller and has a few advantages. Firstly, it’s a power efficient device, which is saving a lot more battery life. The new version uses a low power microcontroller and manages the power to the LEDs.

The Larson Scanner has nine LEDs. The “eye” scans from back and forth across the LEDs. In order to achieve the smooth scanning, you have to lit up to five of the LEDs to various its degrees at one moment.

One more thing, you should wire the battery box go up through holes in the board, before looping around.
