Awesome Stuff: A Mesh Network For Your Things

from the never-forget dept

Plenty of people have tried to market various devices for keeping track of your keys or never losing your wallet, but they’ve tended towards the cumbersome and gimmicky, and have always been pretty limited in their function. This week, we’re taking a look at a much cooler approach to the same problem: little computers called Trakkies that attach to your things and link them all up in a mesh network.

The Good

Trakkies are a great example of innovation at work. The problem — people losing their keys, forgetting their bags, etc. — has an obvious solution in a world of wireless technology, but implementing that solution in a functional and stylish way that makes people say “wow, I want that” is another challenge altogether. Trakkies go beyond a simple proximity or location system, and instead make all your stuff smart. The little node tags come in two sizes, each with a bunch of sensors and a big configurable button; they locate each other and form a mesh network with Bluetooth and NFC connectivity, and begin learning what you bring with you and when. Your wallet can warn you if you’re leaving the house without your keys, and vice versa — or you can tap the button on any one tag to find out if all the others are with you. The associated mobile app is optional (a beautiful thing) and brings your phone into the mesh network without the need for an an attached node tag, plus provides additional tools like looking up the last known location of all your tags on a map.

The network can communicate with lots of other smart devices and can be hooked into IFTTT for programmable behaviours based on a wide variety of factors. And the buttons on each node can be set up with context-sensitive functions — so the button on your coat could be set to tell you if your phone isn’t with you, but serve as a music skip control if it is; it could check for your wallet and keys when you’re getting off the bus, but turn on and off your smart lightbulbs when you’re at home. Trakkies take a big leap beyond solving a simple problem, and actually spark excitement about the new things they could enable.

The Bad

Truthfully, at this stage, I don’t have much bad to say about this project. I’m looking forward to seeing where it goes. The price isn’t cheap, but it isn’t prohibitive either, and the designers have made what I’d consider all the right choices. The “internet of things” has been looming on the horizon for some time now, and a device like this could represent a meaningful step in that direction.

The Background

There’s an interesting bit of backstory to the Trakkies on the Kickstarter page: the whole thing actually started as a software pursuit. The original team was a research company at European Space Agency BIC, and was focused entirely on the data science and machine learning aspects of the project. The switch to a focus on hardware only came when the team realized that nobody was making hardware capable of doing what they wanted their software to do. That’s the path innovation often takes, and beautifully illustrative of the fact that the simplest problems — people sometimes forget their keys — can yield the most interesting and groundbreaking solutions.

Re: Re:

Something like this maybe useful for a car or a dog I suppose (assuming the dog doesn’t destroy it or figure a way to remove it). There was another similar interesting tracking device that was mentioned on Techdirt at one time, I can’t remember. However, IIRC, the other one didn’t allow you to change or charge the battery and so you had to replace the device every so often (I believe it was every two years or so). It synched to an app on your phone and it synced to anyone else who has the app on their phone so that if your car gets stolen, for instance, and it gets in close proximity to someone else who has the app the app will notify the network, which will notify you, of your car’s location.

So does this one allow you to charge it? How often must you charge it. Or does it allow you to replace the batteries? If so what kind of batteries does it take and what is the battery life? Or do I have to get a new device every once in a while, how much will they go for and how often must they be replaced?

Also it would be interesting if someone could create an app that could turn an old unused cell phone into something like this. Something that can synch to other cell phones via an app notifying them of its presence. So, for instance, if your car gets stolen if the cell phone encounters another phone with the app the app will then notify the network, which will notify you, of the phone. Perhaps if there was a way to hide it in the car somewhere so that it can draw power from the car.

Re: Re: Re:

The key difference between this and other such devices is that these tags for a mesh network. As far as I know, nobody else has offered that. Systems such as the one you describe use the phone as a hub — it locates all the various devices that are tagged. That is not the case with Trakkies: each device is independent and they all form a network, and each one is capable of locating and interacting with all the others. There’s no hub, no centralization. That’s what makes this stand out to me.

As for the charging, I’m not sure if they are chargeable or not, but they DO have replaceable standard flat batteries that you can pick up almost anywhere.

From the actual page, they expect an 18-month battery life using CR2450 (630mAh) batteries in the .micro tag (⌀29x12mm), and an 8-month battery life using CR1632 (130mAh) batteries in the .tagg tag, user changeable. Those batteries seem to go for about a dollar each, from a quick search.

I think it’s awesome what they’re squeezing out of the tech – the devices contain multiple LEDs and the page mentions triangulation, which may mean that they’ll be awesome for locating your wallet when it’s fallen behind the sofa. I think they have an uphill battle convincing people they need the devices though – As Leigh mentioned, people are used to being disappointed by these things.

Re: Re: Re:2 Re:

I agree that having the missing device make a noise is likely to be more practical in most situations, but if I dropped my wallet while jogging in a park I might prefer it not to call out to other people. Also, if buried under sofa cushions sometimes it can be hard to hear small speakers.

Also, there’s nothing wrong with a signalling mechanism that’s accessible to the deaf 🙂

That’s the problem I’m having with my software project. I wrote a program to control warp drive engines on starships, but so far I haven’t been able to find anyone making hardware that can run my software.

Re: Re:

Yeah, at this stage in development they should switch from 802.15.1 to 802.15.4 so they can’t talk to your phone any more, they have to find a new SoC and probably redo a whole bunch of the design work that they’ve already completed.

Not saying that this kind of device using Thread wouldn’t be a good idea, but what would this particular group possibly gain that would be worth switching to Thread?

Trakkies’ mesh topology is a step in the right direction, and the use of Bluetooth/NFC is good when you know you’re only a short distance from your devices. What I wonder about, though, is the potential use of a system that can track an item — let’s say, a corporate ID card — across a large area through a WAN. Maybe something like Symphony Link for corporations, or ZigBee?
