This estimates that at 4.5 GH, 19339258.2724 difficulty and $108.55 USD/BTC, the jalapeno will generate 3.56 BTC/month or $386 in month 1. Even at 10x difficulty, that's $38.6 per month.


another, more extensive calculator, http://www.bitcoinx.com/profit/

This one reports 0.13 BTC/day.

i haven't a clue what the final power numbers are for the jalapeno, but if it draws 100w and electricity is $.15/kwh, then what, power will cost a whole 36 cents per day? Not too bad...  so yes, even if difficulty goes up by 10x, i'll be well past paid back for the unit and will bring in $35+/month...
