Almost exactly a year ago I published a blog post introducing an open source application for calculating cycloidal gears. The response was very positive but the fact that the tool depends on a specific version of .Net makes access a bit cumbersome. Also the tool does not immediately show the resulting gears. Instead the user has to save the output as an SVG file and then display it either in a browser or an SVG editor like Inkscape. No instant gratification there.
All these issues are addressed in my new Online Cycloidal Gear Builder. Check it out!
