Goal
A simple terminal to allow people to select & play music.
Down the road it might be nice to use the device to accept koha - or event be combined into a Freedom Toaster
Requirements
Skills
- Electronic & Mechanical
- Computing
Resources & Equipment
- 1x x86 PC
- Monitor
- Sound card
- Speakers
- Input device
- Storage
- Audio equipment
- "Pokie" slot machine
Basic Design
The design should be centred around simplicity of use
v.0.x
- x86 running Ubuntu & MPD as a service
- Skinny X
- use ~/.xinitrc to autoload Sonata or another MPD client
GMPC seems to work well; hooks self-defined keys well - dealing with resizing issues Jaco
- Serve up MPD client web interface for network control
v.1
- Integrate buttons on Pokie machine, mapped to basic keyboard media keys, to control X-based "fat-client"
- Play 8-bit MIDI sound & flash some lights for Koha dropped in slot
Controls
Pokie has 5 pairs of buttons + 2 extra
- Up & Down keys (2)
- Page-up & Down (2)
- Search, pop-up keyboard
- Select / Add to queue (1)
- Play/pause, Next (2)
- Volume Up & Down (2) (optional)
v.2+
Monetize device to rent out (events, etc), to raise revenue for space
- Random visualization on a separate screen
- Commercial library
- Money for tunes
- Plays Creative Commons music when "idle" - available for free donwload
- Track plays for direct payment to artists
- Ability to play from external sources:
- Auxiliary analogue input (minijack)
- Removable media over USB interface (security risk)
- iPod's, etc
- The "Cloud"
- SoundCloud, Jamido, GrooveShark, etc
- iTunes account (pay by voucher)
