The kickstarter satellites. Sandy Antunes, the author of the blog post has built his own picosatellite Project Calliope. A project he also chronicled in his blog Satelite Diaries. NPR story.
Sandy Antunes has also written a book, DIY Satellite Platforms. Via Cool Tools.

Yes, we need more space debris.

That said, given the height that those cameras on balloons get, could you build a 2 stage balloon + rocket to get you to a stable orbit? I suspect not, otherwise it would have been done already.

These ultra-LEO (Low Earth Orbit) satellites barely qualify as debris. The orbit probably decays on the order of months.
After a bunch of searching, I found this on his site: I'm doing music from space, using a 200 gram instrument in a half-kilogram case launched 312 kilometers up. What 200 grams would you put into orbit?
A little more googling turned up this paper on an orbital decay rate simulator which happens to have a sample run for a 300km orbit on page 5. Decays after 46 days.
