wow, means a ton. my daughter has actually been insisting that I sell them and had to get her approval to open-source the code this week.

Code and materials are on my github: https://github.com/pneedleman/reclaim-spotify-clock The off-the-shelf hardware runs around $60.

If enough folks would rather have a pre-assembled plug-and-play kit instead of soldering it themselves, I might seriously look into doing a small-batch run or Kickstarter.
