Using this equation you can make a spreadsheet with columns as ring sizes and rows as gear sizes to help you choose the numbers of teeth for the elements of your toy.
Excel has a function for least common multiple, and thus it's easy to write a formula this purpose:
=LCM(B$1,$A2)/$A2
where B1 contains the number of teeth in the outer ring and A2 contains the number of teeth on the gear; see the screenshot.
...Or just download the Excel file below.
As you might expect, for rings with a prime number of teeth, the number of points is always that number. For gears which have a prime number of teeth, they result in designs with a number of points equal to the number of teeth in the ring.
* Perhaps this value has another name, but I'm no mathematician; please let me know if there's a more simple name.
Android (Rooted): AirAudio is a utility that lets you Android phone or tablet play nicely with your AppleTV, Airport Extreme/Express, or any other AirPlay compatible device in your home entertainment system. Best of all, it's free.Your Android phone needs to be rooted for AirAudio to work, but if it is, you'll be able to push any audio from your Android phone—whether it's a streaming music or pre-recorded audio, to a set of AirPlay compatible speakers or audio devices. Once installed, all you have to do is select the available AirPlay devices on your network, set the output volume, and listen while your music comes out of the big speakers instead of the small ones. You can even play your Android's audio through multiple Airport receivers at the same time.The app doesn't technically require Ice Cream Sandwich, but ICS users will get the most benefit. There are two audio output modes: "system audio" and "microphone." Microphone is great if you want to speak into your phone and hear it through the speakers, but "system audio" is what you really want to use. On pre-ICS devices, "microphone" is the only option, and it essentially plays your audio on your phone and uses microphone mode to pass that audio to your AirPlay speakers. It's a little echo-y, but it works, even on unsupported devices.AirAudio is free, and it's a great option if you're rooted and running ICS. If you're not, it's still worth a try if you can't find another app that bridges the gap between your Android phone and your AirPlay speakers.
