>>This Independence Day I designed a couple of small cheap switching

I've seen a number of these designs on the PICLIST from time to time.
Why build this out of discrete components like this when you can buy
an IC based item?  Is it a cost thing, or does this give better results, or
is it just a "because I can" type of thing?

Not to undermine your work, mind you, I think it's just spiffy, but why?
