When it comes down to energy management, having real-time data is key. But rarely is up-to-the-minute kilowatt hour information given out freely by a Utility company, which makes it extremely hard to adjust spending habits during the billing cycle. So when we heard about [Jon]‘s project to translate light signals radiating out of his meter, we had to check it out.

From the looks of it, his hardware configuration is relatively simple. All it uses is a TSL261 Light-to-Voltage sensor connected to an Arduino with an Ethernet shield attached. The sensor is then taped above the meter’s flashing LED, which flickers whenever a pulse is sent out indicating every time a watt of electricity is used. His configuration is specific to the type of meter that was installed by his Utility, and there is no guarantee that all the meters deployed by that company are the same. But it is a good start towards a better energy monitoring solution.

And the entire process is documented on [Jon]’s website, allowing for more energy-curious people to see what it took to get it all hooked up. In it, he describes how to get started with MQTT, which is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol, to produce a real-time graph, streaming data in from a live feed.

Now, with all this valuable information, other applications can be built on top of it. Interfacing with something like the Pinoccio microcontroller system can allow for devices to be turned off during peak-power times, helping to reduce the billing price at the end of the month.

Energy-intelligence platforms like this assist in conserving electricity while keeping the rate-payer consistently informed of their power usage habits. A real win, win. However, we still need to figure out how to (legally) extract the data from other types of meters.

One example is to harvest the information wirelessly with a special USB dongle to gather the data emitting from the Utility meter. But this only works for that brand of meter. Another solution is to read infrared flashes with an AVR, a resistor, a capacitor, and a phototransistor, which is similar to what [Jon] created above.

So, what kind of meter do you have? And, do you think there is a better way to extract the kWh data? Let us know in the comments, and let’s see what we can come up with.

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

It's been said that imitation is the sincerest form of flattery. Improving on a good idea, however, is truly the ultimate homage, according to the makers of the new Pinoccio microcontroller. Inspired by the Arduino, the brain trust behind the Pinoccio decided to take the stuff they liked about the popular platform -- ease of programming and low cost -- and add some features to make it even better. These include a rechargeable battery, a temperature sensor and a built-in radio that allows one Pinoccio with a WiFi shield to communicate wirelessly with other Pinoccios. The microcontroller also delivers performance that stacks up well with an Arduino Mega but at a smaller size -- the Pinoccio only measures a couple of inches long and an inch wide. The project is currently trying to raise $60,000 at Indiegogo, with supporters netting the standard Pinoccio by pledging $49 and a microcontroller with a WiFi shield for $99. For more details, feel free to check out the video after the break or peruse the project's Indiegogo page by clicking at the source link.

Previous project update: The Lomography Smartphone Film Scanner was apparently ready for its closeup. The Kickstarter project more than tripled its $50,000 goal with two more weeks to go.
