How does one create an altcoin?

[HDutchie]

Hello all. I'm looking to make a very simple SHA coin called TestCoin (for miner testing, etc.). How exactly would I go about this? I would prefer NOT to use a service like CoinCreator if possible.

Thanks,

Do what every other coin 'dev' does and copy the source code of another coin then change a few parameters, make sure you call it innovative and premine half the total coin supply.

Does seem to be lots of preminie going on, but not all altcoins have this issue

this is pretty much it: https://bitcointalk.org/index.php?topic=225690.0

then some find/replace:

find /root/newcoin/ -name "*" | xargs perl -pi -e 's/oldcoin/newcoin/g'

create new genesis block. go to town. rinse repeat.
