If you are better at github than I (shouldn't be hard 
) a Fritzing part appears to be here (but I can't figure out how to download it from github the usual download button is missing):
found via google with search term "fritzing part EL Sequencer" which is always a good place to start especially with sparkfun. The rest of the stuff you need isn't that difficult to make the sequencer looked to be the most work and it looks to be done if you can access it. Ah, I may have been in the wrong repository, it looks to be here which is downloadable, what I was looking at was a fork from the main repository apparently:
The panel and inverter should be fairly easy to make (have a bash at it and post it here if you can't make it work and I'll fix it up for you).
