For http://letscodejavascript.com, I spend about $1000 per month on various services. The biggest expenses go to PayPal, credit card processors, and Recurly, which all charge a percentage of revenue. Other than that, it's SendFaster, which hosts my videos ($200); Heroku, which hosts the site ($66); and Pingdom, which monitors my sites for uptime ($9). I also spend a small amount each year for TypeKit (fonts).

Edit: I should add that Let's Code JavaScript isn't a side project; it's my primary revenue stream.
