Timer Circuit Answered
I found this simple circiut on jamesyawn.com, and was wondering if and how to change it so that it could time in the minutes, longer than it does already. I don't know anything about electronics, aside from soldering, and basic connections, so try to give a simple-ish answer. I also wondered about what transistor to use (like a radioshack part number). The circuit I was talking about is under "discrete timers".
(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.
