  1. After seeing @Sariel's post about the new 28 tooth gear, I created an Excel sheet that can be used to find the perfect (if existing), loose and tight fits between two Lego gears. It's only applicable to gears aligned along the same axis, so perpendicular and worm gears will not work - for now. Here is the link to the Excel file, located on Google Drive: https://drive.google.com/file/d/1FrAuXUNHenaWSZgvIRfyscusqirnu2Nw/view?usp=sharing I hope it's useful.
  2. Hello all, I have been working on a Lego EV3 calculator recently and have incorporated quite a few functions into it.However, there are two functions I would like to add that I don't currently have. The functions that are already in it are as follows: Add Subtract Multiply Divide Exponential Square root Factorial (this was a pain to make!) Sin ASin Cos ACos Tan ATan The two that I would like to add are an Xth root of Y function and a Log() function. If anyone knows any way I can program these blocks or any ways you have seen yourself, please post a reply! Thanks, Jim
  3. Hello all I just thought of an interesting concept for technic supercars, that could help compare them properly. As we all know, the real supercar world is a buzz about power to weight ratio figures and such. I know you would probably think this is pointless for a technic supercar, because you would expect its power to weight figure to be so low but, it's still a neat way of comparing them. Because some technic supercars are heavy but powerful and others are the opposite. So I have researched a formula to work out power to weight ratio for real cars, and thus used this for technic models, and have also worked out the power and torque of every modern technic motor: Xl motor, L motor, m motor and possibly RC motors. Here are some power to weight figures from 2 of my motorized supercars: My Lamborghini Huracan *1.3kg *0.004hp = 3.08hp per ton My Mclaren P1 *2.8kg *0.008hp = 2.86hp per ton. As you can see. eventhough my Mclaren has 2 Xl motors and my Lamborghini only has 1, the Lamborghini edges out a better power to weight ratio because its less than half the weight of the Mclaren. Which explains why my Lamborghini is almost twice as fast as the Mclaren (apart from the fact that the Lamborghini has a 3 speed gearbox, 4wd and better gearing, and the Mclaren just has 2 Xl motors powered to a differential.) Thank you for viewing this topic, if you have any questions feel free to ask. If you have any motorized mocs that you would like me to work out their power to weight ratio, just tell me their weight in kilograms, and how many motors it's power by e.g. 1 Xl motor or 2 L motors. I'm not sure about RC motors but if your moc is powered by RC motors I will try my best to work it out. LeocornoProductions
