Mpeg 1 layer 3 compression based portable jukebox - Started at the begining of July 1999
The idea was to build a box for use at parties which was more portable than the full size jukebox.
This was for a lot of parties, and lent out many times, but was really heavy, and even when painted didn't look too good.
- Hardware :-
- A Pentium motherboard with on-board audio and video (no plug in cards means it's less than 70mm high).
- A Cyrix 225MHz processor (a PR300) (although a Pentium P120 just about works).
- A pair of 4.3G drives, on rubber mounts (to protect them a bit more during transit).
- A standard PC power supply, removed from it's original case, with heatsinks modified to fit.
- Shares the mpeg 1 layer 3 decoder from the Mark 2 (Source code).
- Enough disc space for over 2000 tracks.
- Best next track search from the Mark 2.
- RS232 (any VT52 or VT100 terminal) or keyboard/VGA menu driven interface.
- The PC/PSU/HDD is built into 2U 19" rack mount case. with the display and key selection built on top.
- The HDDs are on rubber mounts, to give them some shockproofing during transit.
- Designed to be idiot and beer proof, so only has a few buttons.
- The menu display presents a few lines of instructions, a status line and 21 lines of tracks.
- The tracks are listed in "artist" or "track title" order
- The cursor keys scroll through them.
- Point to a track and press "enter" to add it to the play list, it's as simple as that.
So I went on to develop the Mark 4 - AKA Portable V2
