Cool garland like Alex Gaiver (WS2812)
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. The garland is really very cool, it just causes a storm of emotions in the audience.
I soldered the garland myself, cut the WS2812 addressable LED strip into modules, soldered with the help of pieces of audio cable with a cross section of 0.25 mm. I got a total of 120 diodes. The power supply used 5 volts 5 amps. The garland is fastened to the window with an adhesive tape and it does not interfere with opening the window for ventilation. The Arduino board is connected below, there is also a common power bus on the bottom of the wire with a cross section of 2 * 0.75 mm. The maximum current consumption of about one ampere, judging by the multimeter, but the usual charge of 2 amps from a mobile phone I could not cope with this load.
The project is quite simple and it should be repeated. I spent a couple of evenings to solder everything, the setup took only a few minutes, and the effect is simply amazing! Congratulations to all the upcoming New Year! Creative success!

I present to your attention a homemade 3d printer. Assembled from plywood, aluminum, plastic and Arduino. This printer is unique in that its kinematics is peeped from Ultimaker, but done with quality modifications.
This device helped me to saw a bundle of rolled metal at an angle of 90 degrees without effort.
I made this CNC machine myself in 2015, videos of the same year. For a long time I was asked to make a video on the assembly of this machine, later my hard drive broke, by some miracle I found some materials on this machine on another medium. After almost 4 years I will publish the materials, as I did with my own hands a CNC machine tool from the available materials.
Today, instead of round guides, the printer received square, using a conventional aluminum profile tube with a cross section of 20 * 20 mm. Bearings roll along the pipe 623zz. All plastic parts were printed on the same printer before it was altered.
I had a new passion - brooches of felt. Such small, lovely - they can be an independent gift or an excellent surprise to the main.
