Android LEGO Gear Ratio Calculator app now available

Please, add meters per second when calculating speed.

Now there are km/h, mph, knots and machs (!).

Divide km/s by 3,6 and you'll have m/s.

Following your suggestions I have extended the list of speed units available for calculation. It now includes centimeters, meters, inches and studs per minute and per hour. I've kept the unladen swallows, of course ;)

Update to version 1.17 today: https://play.google.com/store/apps/details?id=pl.sariel.brickgearratiocalculator

I just install it.

Works pretty well. It will replace my excell file instantly.

Thanks for your time invested in this cool app.

You should be seeing version 1.18 already: https://play.google.com/store/apps/details?id=pl.sariel.brickgearratiocalculator

In this version there is a huge new functionality called COMBINATIONS FINDER. In it, you can specify the gear ratio you want to obtain, the number of pairs of gears you want to use, and the app will calculate a solution for it. If there is no exact solution found, you will get the closest result possible. If the given gear ratio can be obtained with several combinations of gears, all of them will get listed. I hope this will help you, just keep in mind that calculating solution for 4 pairs of gears can take 10+ minutes depending on the device. This is also the reason why I didn't add option for 5, 6 and more pairs of gears - this would likely melt your device :)

Great add-on! Thx!

Edit: Since you've offered your finger let me please bite off you whole arm : It would be really sexy if the results came out in gear pictures

Hi! 

Can you add worm gears to the "Gear Coupler" tab? 

Also there is absent an arm with gear (24014) in the gearcyclopedia tab. 

If you update the application, then I'll rate it 5 (!) stars on Play Store!

It would be cool if you could choose to have x amount of gears stacked on one virtual axle  then y amount of gears stacked on another virtual axle.

The axles can be spaced as multiples of plates or multiples of half beams.

But then you have to start handling gear combinations that will jam up.

But at least that will teach people about simple and compound gear trains, ratios, and if they will jam or not.

Example:

On axle A I could have a 12 tooth gear

On axle B I could have a 20 tooth gear then a 12 tooth gear

On axle C I could have a 20 tooth gear.

The axles are spaced 1L apart.

I could also however have them on 4 axles all in series rather than as a compound gear train.
