EasyEDA tips - edit components

EasyEDA like many other CAD allows to create your own components.
There are lot of documents and tutorials on the net, but still some information are often hidden or not easy to find.
Hopefully these tips can help.

Privacy anyone ?

I did find a project related to Amazon Echo or Google voice and is somehow interesting, under some points of view.
This project is basically a "piggy back" contraption  to be put over an Echo or Google device.
The gadget constantly send out noise to the "home assistant" until a specific word is said.
This supposedly should solve the allegedly privacy problem.

Storing projects - the idea

How to store a project to preserve it for the future ?
My project have up to three components.
A description/documentation. some code, schematics.

I like the idea to have my work not only stored in different servers like Bitbucket or EasyEDA or Blogger but also stored on my server, locally.

I left the geiger turned on for few hours in the same position.

Radioactivity measurements - introduction

Just for fun I started to collect some radioactivity measurements.
I did something similar 35 years ago in Italy with a DIY kit from Nuova Elettronica.
Why ? Well, as I said, just for fun and curiosity and don't forget we have a nuclear plant in Arkansas. Never hurt to monitor if something fishing is going on (and no, so far everything is fine for what I can say :) )
