Sariel posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingNo, I'm not back, have no fear, just passing through sharing something that may benefit some of you, and then I'll be out of your hair. Long story short, I have reworked the few online tools I have created previously, updated them, upgraded then with extra options and added a few new ones. Some of them were written 10+ years ago and it was showing, so now they're all standarized, built around the same core using Bootstrap Shards, which ensures good cross-browser compatibility, decent handling of mobile devices and optimization for use with touchscreens, plus some modern bells and whistles that just make everything better. There are now 11 tools total available for you at tools.sariel.pl and here's a complete list with updates. Enjoy! Gear Ratio Calculator: overhauled layout with tabs checkbox for adding planetary wheel hubs to the final gear ratio updated list of motors option to select not only type of a motor but also number of motors new 'Gears and numbers of teeth' tab helping to identify which gear has how many teeth all gear images rendered anew for more clarity planetary gear ratio calculator now calculates ratios for all three possible setups detection of incompatible gears and warning when you select them (this mainly applies to 14t gear and worm gears) annular 60t gear added to both standard and planetary calculator updated, clearer images in the gear coupler gear coupler now includes combinations involving the 28t gear Pulley Ratio Calculator: overhauled layout added images representing parts updated list of motors selecting a motor now provides calculation for torque too, not just for speed Model Scaler: overhauled layout adjustable canvas size to accommodate really huge images all boxes can now be collapsed to save screen space solved the issue where the canvas with lines would move up/down the screen but labels stayed in place Unit Converter: overhauled layout Angles Chart: brand new tool, lists angles created by single LEGO pieces; every piece can be zoomed in and the list can be filtered by categories Wheels Chart: overhauled layout the list can be filtered by categories up/down indicators added to column headers to make sorting clearer Monorail Network Planner: overhauled layout code fixes for modern browsers Town Plot Planner: overhauled layout code fixes for modern browsers Bricksafe Thumbnail Helper: overhauled layout clearer indicators for selected images single button to mark & copy the generated code Brickshelf Thumbnail Helper: overhauled layout clearer indicators for selected images single button to mark & copy the generated code Brickshelf Stats: overhauled layout code fixes for modern browsers If you encounter any issues with these tools and you have used them before, try clearing your browser's cache.
BusterHaus posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAfter 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/1HbPf6p3Jrai7kZgvk_BcaS5grUOOpE4q/view?usp=sharing I hope it's useful.
Technic Jim posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHello 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
LeocornoProductions posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHello 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
