RSSFlickr user solipsistnation created this rather awesome sample sequencer using Meggy Jr. and an Arduino WaveShield -
The Meggy Jr RGB from Evil Mad Science running MeggySeq, driving a Wave Shield from Lady Ada. MeggySeq is a pattern-based drum machine sequencer. It has 8 patterns of 16 steps each and each step can play one of 8 samples (the colors are hard to tell apart on the video). Next steps: Saving patterns to the eeprom, sending MIDI (currently it just sends single characters over serial to the WaveShield) and possibly syncing to external clock sources. Or, you know, changing the tempo at all.Agh - such coolness! No sign of source code as of yet, but the setup apparently uses another Arduino along with the aforementioned WaveShield.

Yep, one Meggy Jr RGB and one arduino with a waveshield, connected over serial.
Run the MeggySeq.pde code on the Meggy and the listener on the arduino/waveshield.
Last night I rearranged the code a bunch, added a tempo display, and fixed the timing so it's more flexible. I have another thing to add, and I'll upload that code (and possibly a movie of it running) later today... I need to write up the cable, too...

I just finished implementing and testing pattern copying (and clearing) and saving to and loading from the EEPROM.
Tomorrow, more flexible looping and better switching between patterns. I think that plus swing quantization will be about the point where the interface will get too crowded to be usable.
This weekend, a writeup on what goes into it, with photos.

very excellent - thnx for keeping us updated!

I got a couple of other pieces set up. Once I have looping implemented, I'll release it!
