[Highland Park] looking for used/broken electronics

I am freshman in High School and I will be attending SciTech magnet school. I have a real interest in computer sciences and engineering. I am looking for used/broken electronics that I can deconstruct and experiment with. I'm not interested in anything that is rusted, dirty, corroded, or anything containing toxic chemicals. Here is a list of example items I would be interested in: cameras, I Roombas, phones(cell or land), computers or computer peripherals, speakers, flashlights, CD players, watches, video game systems or controllers, Nintendo DS,or circuit boards. Call me at (412)361-4842 and ask for Sam or email me at cobra5707@gmail.com. Thanks
