Garland with a heart on February 14
Soon, February 14, Valentine's Day, a Christmas garland is still hanging on the window with address LEDs, and I decided to diversify it a bit. I wrote a simple script and added a colorful heart to the firmware.
There was already a post and video about this garland , it works on Arduino with Alex Guyver firmware. I did not write something of my own, just supplemented the firmware with my new effect.
Watch the video, there is instructions on how to do this, the archive with my firmware can be downloaded from the link.
From the street, the heart looks generally awesome! :)
This article is about how I collect my robot vacuum cleaner. There are a lot of photos and videos for those who also have such an idea.
This is my first CNC machine assembled with my own hands from available materials. The cost price of the machine is about $170.
It has long been stored on the computer three photos of the vase, once found on the Internet.
A beautiful, voluminous heart of paper can be glued together in a couple of hours.
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.
