I made a totally from scratch version that should fit in nicely - everything the original already had should fit into this one - including the screws. So there are no additional parts to buy, just print and away you go! Great upgrade for the SV06 Plus.

This is a small project I did with my daughter to make a functional set of traffic lights using an ATtiny chip. If I find the code, I'll add it to this project. However the code was very simple just to change to the next light (like real traffic lights do) when the button is pressed.

This was a full 3D model to print. The creator had the full solid design as an STL, however it wasn't broken up into pieces to be able to print them out. So I set about breaking up the parts, and then printing it out. It was a fun project me and my 7 year old daughter did together! Three months later, and this cute robot has kept her plant alive! She fills up the tank once every 2 weeks or so, and has been great learning experience. Highly recommend it for everyone!
