Schematics

BlueMatrix is made by some different modules I’ve already presented and used in previous tutorials on my blog:

The modules are connected as follows:

BlueMatrix is powered by a Li-po battery (1 cell). The battery’s state of charge is monitored by Lipo Fuel Gauge, which sends the actual SoC (State of Charge) value to Arduino via I2C bus.

The Lipo Rider module rises the battery voltage to 5V to power all the other modules and allows to recharge the battery using a simple, mini-USB power supply.

The HC-05 module manages the Bluetooth connectivity: after having established the connection with the remote device, it transparently transport the data received/transmitted by Arduino via serial connection.

An Arduino Uno is the hearth of the project: it manages the display, checks the battery status and talks, using a simple protocol, with the controlling device (Windows application or Android app).

Here’s a photo that shows the different modules:

As you may see, connections were made using jumper wires:

Enclosure

The enclosure for BlueMatrix is made by 5mm plexiglass, thanks to the laser-cutting service by Vectorealism:

 

The vector file is available in my Github repository in svg format (I used inkScape to draw it). Vectorealism is a Ponoko partner; therefore the file is compatible with any of the Ponoko’s factories.

The modules are joint to the enclosure using supports, these too made by plexiglass:

The special design of the supports let you slip off the modules if you need.

In the next page, the software…

Hi Luca,
Blue Matrix is nice!. FYI, Plessey is now manufacturing one of the smallest, thinnest LEDs we call the “dotLED”. It is only 1mm x 0.5mm x 0.2mm and is available in white and blue. You can see it on our web site at http://www.plesseysemi.com. Let me know if you would like to receive some free samples for your evaluation.

Innanazitutto complimenti per il sito pieno di idee e progetti molto utili ed interessanti.
Tornando al progetto Blue Matrix volevo chiedere se è possibile avere il layout dei sostegni di base del contenitore.
Grazie.
Antonio

Ciao Antonio, tutti i pezzi di plexiglass inclusi i sostegni sono nel file per il taglio laser (formato InkScape):

Luca,
da https://github.com/lucadentella/BlueMatrix/tree/master/Case mi fa solo scaricare il file in html. Dove sbaglio?
Grazie.

Luca,
ho risolto :).

Luca,
ho aperto il file “case” con inkScape ma è un template e non riecco a trovare i sostegni. Dove sbaglio?
Grazie anticipatamente.
Antonio

probabilmente è nascosto il “layer” Your Design, selezionalo in basso e premi sull’icona a forma di occhio…

Ciao Luca, vorrei acquistare il display a matrice per costruire una sveglia bluetooth. Ho visto il display sul sito di sure electronic ma non si capisce molto bene i costi delle spedizioni, da dove spediscono e se ci sono eventuali tasse doganali. Potresti dirmi come è stata la tua esperienza con questo sito?
Grazie mille e complimenti per il progetto e per il sito!

Ciao Davide, quando ho ordinato io il display le spedizioni erano incluse; per le tasse doganali è sempre la solita “scommessa”, a volte fermano il pacco a volte no…

Grazie mille luca, tenterò la sorte! 🙂
