Hi

Activities were held in late 2016 / early 2017 with the intention to amuse and involve my younger child. PCB layout makes Mike proud )

Video!

It works

Schematics is done in Eagle, it is really trivial:

• ESP 8266 module
• DC/DC module, so-called "mini-360" from a well-known store (either tune it for 3.3V output and fix it, or replace variable resistor with 2.2k one)
• switch and 3 PWM outputs to servo's

They call it BOM

Mechanical, OpenSCAD

Conventional 9g servos were modified to enable 360 degree rotation and imprinted into 3d model.

Enormous amount of time was spent to tune various 3d models with my imperfect printer.

Some are git-ed, other lost.

Finally, the software!

Sources of inspiration:

• A perfect http server by Jeroen is at the background
• Unfortunately I can't mention the author of javascript example..

Briefly, it's about embedded ESP8266 + html with javascript + websocket.

No need to setup any Android/IOS app

All sources is shared "as is", sorry for this
