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.

There’s a problem with products geared towards building the Internet of Things. Everyone building hardware needs investors, and thus some way to monetize their platform. This means all your data is pushed to ‘the cloud’, i.e. a server you don’t own. This is obviously not ideal for the Hackaday crowd. Yes, IoT can be done with a few cheap radios and a hacked router, but then you don’t get all the cool features of a real Things project – mesh networking and a well designed network. Pinoccio is the first Thing we’ve seen that puts a proper mesh network together with a server you can own. The Pinoccio team were kind enough to let us drop in while we were in Rock City last weekend, and we were able to get the scoop on these tiny boards from [Sally] and [Eric], along with a really cool demo of what they can do.
The hardware on the Pinoccio is basically an Arduino Mega with a LiPo battery and an 802.15.4 radio provided by an ATmega256RFR2. The base board – technically called a ‘field scout’ – can be equipped with a WiFi backpack that serves as a bridge for the WiFi network. It’s a pretty clever solution to putting a whole lot of Things on a network, without having all the Things directly connected to the Internet.
Programming these scouts can be done through Arduino, of course, but the folks at Pinoccio also came up with something called ScoutScript that allows you to send commands directly to any or all of the scouts on the mesh network. There’s a neat web-based GUI called HQ that allows you to command, control, and query all the little nodules remotely as well.
In the video below, [Sally] goes over the basic functions of the hardware and what it’s capable of. [Eric] was in Reno when we visited, but he was kind enough to get on a video chat and show off what a network of Pinoccios are capable of by emblazoning their web page with Hackaday logos whenever he presses a button.

Wearable devices are all the rage in certain circles — looking for a project of his own, [Hector Urtubia] decided to give it a shot with this six-LED necktie.
It used to be pretty hard to make an Internet connected device without spending all your time and effort on making the Internet connection possible — until the Pinoccio came along. It’s a tiny Arduino compatible board which has wireless Internet connectivity built right in. It even comes with a rechargeable battery. If you have experience with Arduino programming, this little guy is a cinch to get running.
The tie itself makes use of six NeoPixels, which are chainable, addressable and current regulating RGB LEDs, which means the entire chain of LEDs only requires 1 digital pin-out on the Pinoccio! [Hector] has even written a library that will extend the Pinoccio’s scripting environment so that the pixels can interact directly from the web or API.
To demonstrate the tie, he decided to hook it up to his MIDI keyboard — enjoy:

Before assuming that the title should be “web crawler,” just shush your shussins’ and check out the video after the break. The Pinoccio, as previously noted, is a board in development as a sort of web-enabled by default Arduino. This makes it perfect for a project like this one where a little rover is controlled from 10,000 Kilometers away, or around 6000 Miles for those of us that dwell in the US.
This setup uses a cell-phone accelerometer in Brazil to allow control of this robot in Nevada. Although close, the control isn’t quite real time, so that has to be accounted for. Something like this could be easily used for a telepresence ‘bot.
If you want to build your own, the assembly time is estimated at 1 hour. Instructions, as well as source code can be found on their page after the video. Although the Pinoccio board won’t be available until at least this summer, maybe this will give someone inspiration to try something similar in the mean time! Continue reading “Pinoccio Web Rover”
[Pinoccio] is currently an Indeigogo crowd-sourced project that aims use the real-world programmability of the Arduino through the internet using a wifi connection. One could rightly point out that this can already be done through the use of a wifi shield. Before ruling this device out, just “shush your shussins” and consider that it’s designed specifically for interfacing with “things” over the internet. This can replace several components (see 1:10 in the video after the break) and should be less of a hassle.
Additionally, with a shield on one of these devices, several other [Pinoccio] boards can communicate with the Internet using this as a hub in a mesh network. This is similar to how the many “smart” electrical meters work, with a grid router being a central hub for communications. Additionally, this board has a built in temperature sensor and a RGB (instead of a single-color) LED, so you can do some interesting stuff with it right out of the box. Assuming this project gets funded, which seems likely at this point, we’re excited to see the projects that get built using it! Continue reading “Pinoccio – An Ecosystem for the Internet of Things”
