Hello,
First I apologize for the delay in responding here.
good at first the idea is to use only analog components, leaving only the two poles (positive and negative) to better teaching and learning, have a better basis of how things work as well as having a wide range of electronic garbage reusable components that can be used.
My project will begin testing with high school students stage, as it's just me in the project, apart from my mentor teacher, this just delaying in a way the project because besides this I have other projects in my university.
this link Instructables I comment on one of my projects: E-waste Project
In the future I plan to go on that side of digital circuits .... but the idea is to take components of e-waste to teach physics to students in both schools and in university and foster their creativity so that they feel up to play and avontade simplebits create new modules, since most of the components are derived from junk mail access to these components will be easier and lower cost of production.
Here a module example I've done, is the coherer module, which functions as an alloy key when it applied an electromagnetic pulse to turn it off should only take a small hit.

Among other possible things with junk mail, how to create a mini Slayer Exciter
Or an Electromagnetic Train
Also interact with other devices and / or equipment that already exist on the market as the conductive ink 'CircuitScribe'

I think this is it haha 
If you need anything, I'm at your disposal
