I've recently realized that several of the little things I've done here and there, are actually worth going back and documenting and sharing with the world. And so, without further adieu, projects I've worked on:

• MP3 Car Stereo
  
• Electronic car start
  
• Firework launcher
  
• Cellphone interfaced to Arduino
  
• Car repair (attempts and successes)
  
• Wireless E-Stop
