Sometimes you just want to do a little heart monitoring without going into debt for the rest of your life (yes, that's a not-so-subtle jab at our wonderful healthcare system). When you can't afford the real thing, this $1 home made electrocardiogram will allow you to monitor your heart as you go into cardiac arrest while opening bills from your previous hospital adventures. This is much simpler than our previously covered homemade ecg, and probably about as accurate (read: not very). [via]
Notice: This ECG cost less to make than an artery clogging burger from your local BK. Therefore, we do not recommend making medical decisions based off of the data received from it.
