The following is adapted from an Instructable I wrote, with a few added photos here.
The Party Animal dancing speaker is a hilarious but awful product. For this project, I’m going to show you how to make it twice as funny and half as crappy by integrating a music player, connecting it to a real speaker and rewiring it for push-button play. I have mine dancing to Too $hort, but you can have yours dance to whatever you want.
[Editors’ note: This same tutorial was originally published as an Instructable. I’m publishing it here for posterity.]
The quality and design of project boards has become so good in recent years, that I almost feel bad putting them together. In this guide, I’m going to show you a simple soldering technique that can make the back of your boards look as nice as the front. You’ll learn how to make perfectly smooth, consistent solder joints that look impossibly tidy.
