Saw at an angle (device for Bulgarians, Fortune, USM)
This device helped me to saw a bundle of rolled metal at an angle of 90 degrees without effort.
Now I'm building a second CNC machine, the working field will be 1050 * 1050 mm. For the frame, I needed to cut a profile pipe and corners. I had a Bulgarian, but I did not want to saw manually, this would lead to big errors. For half an hour I built a simple device that allowed me to cut the metal exactly at an angle of 90 degrees.
I need a tachometer to calculate some mechanisms. For example, to calculate the speed of a robot vacuum cleaner, you need to know the rotation speed of the electric motor and, based on this, calculate the gear ratio of the gearbox.
I thought for a long time to print the case on a 3D printer or to do it manually. It’s easier to print, but I decided to do the first boat with my own hands. I used cardboard as the main material.
I decided to try how my homemade 3D printer will cope with small models, for this I chose mini-toys and printed them.
This cool garland is assembled according to the design of Alex Hyvera using Arduino and an address LED strip. The garland has many interesting effects, a running text, several games and the ability to control all this from a mobile phone.
I had a new passion - brooches of felt. Such small, lovely - they can be an independent gift or an excellent surprise to the main.
