sorry for asking this but I'm 13 and I am really into stuff like this but have no clue where to get any of the following stuff: 1000uF 35v Capacitor 5K Variable Resistor IC Board N3904 Transistor 3.2v AC Adapter I know that I can find most of the other stuff at radio shack have the photo cell (from a nightlight) and a laser pointer which I can wire up rather than using batteries.

Radioshack is probably the first thing that comes to mind, but really, don't buy there because it's really expensive; you should probably look around on the internet(: amazon.com, ebay.com, etc.), it's a lot cheaper.

radio shack or ask around town i know in my city there is a great place where u can get resistors and stuff for like 1 penny each while radio shack is like 5 bucks for a 5 pack
Feb 17, 2010. 8:12 PMcdousley says:

Jan 8, 2010. 8:03 PMcdousley says:
try allelectronics.com im 13 too you should buy a lot cause there is 7 us dollar shipping
Jul 27, 2010. 10:25 AMwillow20 says:
try rapid, http://www.rapidonline.com/ , rapid is good if you what a lot of something and cheap, often the more you by the cheaper they are but you want a big order to get he p+p price down, (share with a friend?)
