MMCedu project - keyboard #1

This article is part of the MMCedu project (Magnetic Memory Core Education) and discusses about a keyboard to interact with the Magnetic Memory Core project.

Digital Encoder breakout

On many projects I use a digital encoder as input device (to set values, select, etc.).
In order to have more flexibility to put the encoder on panels, I usually manually wire it on a prototype board, every single time.

So it is time to have a standard way to deal with this.

Infinity Disney base

Information about the Disney Infinity base.
Going around antique mall I bough few bases.
I'm collecting here some information, would be nice to be able to use the NFC reader for other purposes.

EasyEDA

EasyEDA is a schematic CAD with PCB capabilities, like Eagle CAD, but running in the browser (I'm using Chrome).
For a project I started  I'm trying to use it for schematic and eventually for the PCB.
This is a brief review of my experience so far.

MMCedu project - Introduction

Time ago I wrote an article (Toroid tale) about my early experience in programming.
Electronics always fascinates me, especially digging deep about how things works, so ... here we go with some magnetic core explanations/experimentation and a retro-magnetic core building project, for fun and nostalgia lane.

Electronic components sources

I often need to buy some electronic components.

Where to look for components, tools, information ?

Teirmilab - final building

Ok, time to close the project.
This article will be updated to track the progress.

tRPOf with Trinket - updated

This article is about a RPOf circuit for the Raspberry Pi using a Trinket, thus the name  tRPOf.
The main difference from previous ones, is that this project uses a standard Adafruit Trinket as microcontroller instead the MSP430 in order to use "off the shelf" components with less effort of programming and a LiPo charger/USB DC/DC converter..

Texas Instrument TI Programmer

Often during the week ends we love to visit antique malls and similar places, looking for something to adapt to other uses or just strange things.
Sometimes instead I found things that .. well, something I can not just leave there.

DIY fume extractor

A quick DIY fume extractor.
Breathing fumes when soldering is not exactly an healthy activity.
You can buy a fume extractor but often they are quite expensive.
