(update, more questions)
What kind of timing (like how many seconds) would I get with this?
Using the same stuff shown on the schematic?
Also, how do I pick a transistor?
Are they interchangeable?
What specs should I be looking for?
If this seems like too much, could someone give me a link to a site that would be willing to help with (very) beginning electronics?
AND, how would you recommend making the transfer schematics for home-etched circuit boards? I can't get the component spacing right.
