Is there a DIY way to use a Carnetix unit? That sort of is a DIY procedure.
Now, if you want to build your own, it's certainly possible, but you're better off purchasing one to save yourself some money and headaches.
So is checking the output voltage on your AC power brick. You have the power brick. You look at the label on it. You determine the output voltage.
Doesn't get more DIY than that.
