Sariel's custom LEGO Technic creations
My online tools for AFOLs are now available on GitHub for anyone to download their source code and run them independently or modify them. The tools I have developed for LEGO builders remain popular and needed by many AFOLs. Having recently experienced some health issues, I realized that the availability of such a crucial tool […]
A compact 2-speed transmission design focused on durability and smooth shifting. Free building instructions available. Having experienced a physical damage to a LEGO clutch gear from a LEGO transmission driving ring in my Pinzgauer 712 T 6×6 model, I have tried to find a solution for a durable transmission that doesn’t use clutch gears or […]

A transmission concept focused on flat form factor, with 3 speeds available from a 3-studs tall mechanism. Free building instructions available. LEGO transmissions come in all sorts of form factors, but sometimes you’re limited in using them in your build by one particular dimension. To address that, I came up with a 3-speed transmission that’s […]
A mechanism that transforms a PF Servo motor into a stepper motor that can rotate infinite number of times left or right. Free building instructions available. Stepper motors are essential in operating many LEGO mechanisms, for example remotely controlled transmissions, and the only ready-to-use LEGO stepper motor is the Power Functions Servo motor. The problem […]
