How to build a replica DSKY unit using an electroluminescent driver circuit and screen-printed conductive ink.

This is VT-100 and XTerm compatible video terminal implemented on the PIC32 microcontroller. It has a serial interface with TTL or RS-232 signal levels, input from a standard PS/2 keyboard, and output to a VGA monitor. There is also a USB interface that supports serial over USB and acts as a USB-to-serial converter.

This is the Juuke box. The Juuke box is your own musical friend, made to be as easy as possible to use. It is especially designed to be used by elderly and kids, but can of course be used by all other ages. The reason we created this, is because of my girlfriend's grandmother.
She told me that her and her grandma sitting in the kitchen, listening to music, dancing and laughing. Sadly, through the last years, her grandma has been in and out from hospital. On her worst days, however, music is one of the few things that still makes her smile. And music players like CD players are just too hard to use for her. That’s why we created the Juuke.

The Juuke Box works by using RFID cards to play specific songs from an SD card. You could also play the songs randomly using the green button, or play and pause with the red button.

saw this cool project a little while ago right here on Instructables. The author Ananords created an RFID music player that could be used by children or people who might not have the capacity to be able to operate a normal mp3 player/device. The original project is called Juuke can be found here. He created this project for his girlfriend's grandma and it is the perfect project to make for someone with Alzheimers or Dementia. This bit really hit home for me, as I lost one of my grandparents to this awful illness and I know that she would have loved something like this.

The basis of the project is that the player has two buttons, one to play/pause the music and one to shuffle all of the songs. You can also select an RFID card and place it on the reader to play that particular song. It therefore takes some of the nostalgic parts of listening to music (like choosing a physical CD or cassette to play) and combines them with new technology making it accessible for those with certain needs.

Even though my Oma (Grandma) is no longer with us, I still wanted to make the project and when my parents were cleaning out some old things from their house, I came across my mum's old cassette player, and thought 'this is it'! I've used the cassette player as the basis for my very own Juuke. I put together everything as per Ananords' instructions and it all worked well, but I had a couple of other ideas that I wanted to incorporate including:

The ability to play an entire album from one RFID card,
The ability to skip to the next song,
The ability to play a 'side B' of the card, just like the side B of a cassette tape, and
Utilising the same amount of buttons, but incorporating long/short press functionality.

Spiel 1
Das erste Spiel ist für 1-4 Spiele gedacht. Es handelt sich um ein Spiel indem man einen festen Punkt „fangen“ muss. Es gibt eine laufende und einen stehende LED. Man muß jetzt mit seinem Taster genau im richtigen Moment, wenn die laufende LED die stehenden LED kreuzt, seinen Taster betätigen.
Wenn man alleine spielt, bekommt man einen Punkt, wenn man daneben liegt, bekommt man zwei Punkte abgezogen.
Wenn man mit zwei, drei oder vier Spielen spielt, ist das Punktesystem das selbe, es bekommt aber nur der den Punkt der auch als erstes gedrückt hat. Sollte der erstgedrückte daneben liegen, bekommt er natürlich auch die zwei Punkte abgezogen.
Dies geht über 30 Runden, die immer etwas schneller werden. Wer am Ende die meisten Punkte hat, der hat das Spiel gewonnen.

Spiel 2:
Das zweite Spiel ist ein reines Spiel für zwei Personen. Dabei handelt es sich um eine Art Aufbauspiel. Man hat gegenüberliegend seines Knopfes einen seiner Farbe entsprechenden eine farbige LED. Rot oder Grün. Daneben ist jeweils ein Blauer Punkt und viele Weiße. Die Weißen markieren das jeweilige Spielfeld. Sobald man das Spiel startet, kommt ein weiteres Licht hinzu welches die ganze Zeit von links nach rechts und zurück läuft. Man muß jetzt immer im blauen Feld drücken um sein Rotes oder Grünes Feld weiter aufzubauen. Wenn man an der falschen Stelle drückt, bekommt der Gegner 5 Züge Vorsprung. Wer als erstes das Spielfeld voll hat, hat gewonnen.
