What a long story iStrohm is dirt cheap!

But the phone isn't, and these are alternatives for those who don't
have them.

For those of us who still have slide rules, this shows how to
calculate power by timing the meter rotor:

The Kill-A-Watt EZ can predict the cost of using an appliance for a
month from a typical day's use, such as making coffee. It breaks down
electricity use to the level where you can make choices, unlike
measuring the entire house. It won't help with wired lights or 240V
loads, but you can capture infrequent short-duration ones like a
clothes dryer from meter readings.

The KWCalculator does miscalculate completely
600 r/kWh at 6 seconds rotation = 360 Watts?
This is completely wrong!!!

iStrohm only costs 1 beer for crying out loud and is mobile and does the
job correctly and in a user-friendly and fun way!

Hmm - I don't have an iPhone. How about I send you the beer, and you
send me the iPhone with app and service?

OTOH, I have a free Arduino app for controlling and acquiring all the
data you might ever want for a small portable nuclear power plant. To
get your copy, just e-mail a photo of your reactor. :-)
