I admit I’m still in recovery from the shame brought about by my performance at a recent holiday cookie decorating party, which may be why this project from JKBrickworks looks so magical to me.
I have put together building instructions for the EV Icer, along with the program file for running it, but be sure to read the operation notes below! The icing results can vary drastically depending on many factors. When everything goes according to plan it actually works quite well. All of the cookies in the picture at the end of the post were iced using the machine. To build the EV Icer you only need the LEGO Mindstorms retail set number 31313.
