Square gears from plywood
A friend said like acoo kie, his wife said some windows :) And yet they spin!
I did not come up with square gears, I just repeated. Recently I collected a CNC machine tool and I really wanted to cut out such gears from plywood.
For those who want to cut out such gears, I attach g-code for the machine. In the archive there are two versions of the gears and the source files dxf.
This is my first CNC machine assembled with my own hands from available materials. The cost price of the machine is about $170.
I decided to update the old, already charred stand for the soldering iron. Simple and does not take up much space on the table.
A dancing robot with a height of 60 cm. You can use costumes and accessories. There is wireless control, you can control the movements of the robot.
It all started with the fact that I had a daughter :) Now she is 1.3 years old and she has already learned to deftly sit down to her daddy on her knees and read a book. Each child, like an adult, should have his own chair. Searches in children's shops were unsuccessful, the chairs are all plastic and large or with a hole for the pot. We needed a normal chair for sitting, for a very small girl.
This small turntable is needed when you need to photograph something or shoot a video in 360 degrees. For the assembly you will need an old CD-drive, a couple of pieces of plywood, a box for batteries, a switch, wires and other trifles.
