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 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.
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.
This is my first CNC machine assembled with my own hands from available materials. The cost price of the machine is about $170.
I had a new passion - brooches of felt. Such small, lovely - they can be an independent gift or an excellent surprise to the main.
Almost all toys bought for the daughter do not cause the child's interest, which can not be said about developing toys made by themselves. Below is a photo of the simplest developing mat, which the wife made for a couple of evenings from old buttons.
