Flutter: $20 Wireless Arduino with 1 km range
- AdamFernandez 13y agoI'm imagining quadcopters carrying these out to far flung geographical locations and creating a 'drone net' anywhere (hazardous terrain, repressed nations, etc.).
- jeffreyg 13y agoYou should google for 'wireless sensor networks'. There are some really cool research projects in this field.
- gdc 13y agoI wouldn't be putting too much money up for this until it's clear what frequency they'll be using and what (if any) FCC certification is finished.
- Sparverius 13y agoI'm not clear, what type of bandwidth can we expect from this? I can see this being useful even if it's very low bandwidth, but I'd like to know what I'm getting into. How does it handle interference? I'm assuming 1 kilometer is optimal. How does the encryption affect transfer speed? There's a lot of important questions that need to be answered before I'd consider putting down money on this.
- freehunter 13y agoThe Kickstarter doesn't directly say this, but it uses the ISM band (900mhz in the US). The chip they're using has a maximum throughput rate of 500kbps. They're combining the features of wifi and bluetooth for fast speeds over short distances and supplementing it with an ISM radio for slower speeds over longer distances. Since it has 256-bit AES encryption, I would guess they are basing it off something like an XBee/ZigBee/RFBee.
- solistice 13y agoSeeing this made me think of the exact same question. Also, what bandwidth do you get at 1km distance? By the way, for lower ranges, there are allready solutions out there, like the TI CC3000[1] and the electric imp[2]. They use wifi though. On a related note, don't put weird antenna spouting rat nets projects into central park if you're not looking for some fun with homeland security.

- juliusdeane 13y agoThey're saying max 1.2Mbps on the press page http://www.flutterwireless.com/press.html http://www.flutterwireless.com/press.html
- TaylorAlexander 13y agoIt's been a hectic few days organizing all that information, but here's the lowdown: Currently we are using the CC1101 Radio, which maxes out at 600kbps. It's an excellent radio, but has been basically unchanged since 2006, when TI bought chipcon (who made the CC1101). The CC1200 was recently announced as a successor, and it looks pretty amazing. The max data rate of that chip is 1.2Mbps, and it has increased transmit power and sensitivity. The chip is priced roughly the same as the CC1101 and is based off of the same code, so we should be able to port everything to it quickly and pick up development with it. There is a possibility that the chip will have some flaw that makes it a show stopper, but it's intended by Texas Instruments to be a nearly drop in replacement, and if it does what the datasheet says it should handily work for us. There is a possibility that we will end up not being able to use the CC1200 though, giving us a max data rate of 600kbps in that case, and I realize I need to make that clear, so I will go write up that copy on our Kickstarter page now. I definitely don't want there to be any confusion about what we're selling, so I apologize for not making that clear to any backers, I'll mention the change in our coming backer update, which will largely be directed at international backers, who we are working to accommodate!
- noonespecial 13y agoI'm encouraged to see that projects like these are at least becoming aware that they will face challenges getting FCC certified as intentional radiators (and are required to in the first place!) but I still think they might be underestimating this difficulty. I've seen projects burn $90k going back to the testing lab over and over tweaking this and that to get within acceptable specs only to find when they went to production that a few key things on their BOM were discontinued by suppliers and they essentially had to start over. Best of luck to them.
- ambirex 13y agoIt looks like they are using TI chips for the wireless (CC1101 for prototyping but it looks like they are targeting the CC1200 for release). The have a little more technical information on their website - http://www.flutterwireless.com/press.html http://www.flutterwireless.com/press.html http://www.ti.com/product/cc1101 http://www.ti.com/product/cc1101 http://www.ti.com/product/cc1200 http://www.ti.com/product/cc1200
- noonespecial 13y agoThats actually a really good choice. Like choosing the LTS version of your distro to develop on. Things have definitely gotten better than the "bad old days" my war stories are from. These new integrated radio-on-a-chip are much easier to deal with and manufactures are taking their reference designs seriously with an eye toward helping smaller projects clear these hurdles. Using TI instead of obscure-asian-manufacturer is also a good choice. That said, if they're depending on ($80k - kickstarter fees) alone to get off the ground, I think that's a bit sparse. Then again, they seem to have done an above average level of pre-campaign development.
- rauar 13y agostill waiting for chips which do DSSS (http://en.m.wikipedia.org/wiki/Direct-sequence_spread_spectrum http://en.m.wikipedia.org/wiki/Direct-sequence_spread_spectr... ).
- devindotcom 13y agoVery cool. The type of thing that could be used to set up a nice little mesh network, although I'm guessing it would have to be restricted bandwidth-wise, which is kind of what I always envisioned anyway. Nice that it has that on-chip crypto. Would be good to see how it performs as a mesh in an urban area, though. Would these need to be mounted atop buildings? On eaves? On light poles? Definitely needs a weather-proof enclosure, too!
- xSwag 13y ago1 half mile = 0.804672 kilometres
- aray 13y agoTested to 1 kilometer, mentioned in the Features section at the link.
- joelhaasnoot 13y agoWhich in the end is the range you can get from Wifi line of sight with the right antenna but with much higher bandwith.
- walshemj 13y agoAnd you are allowed to pump more power through 2.4GHZ as opposed to 900MZ and 2.4 antennas have better gain properties.
- devx 13y agoSeems great for meshnets, and I think this is only the beginning of such technology.
- lcasela 13y agoDeff. I'm actually seriously considering starting a meshnet in my neighborhood.
- jjsz 13y agoI'm considering it for my university-it doesn't have a mesh net yet. Like someone said in here, autonomous, self sufficient quadrocopters that power mesh servers is also my dream. What stack and chips / devices are you going to use?
- kgmpers 13y agoI'd give $100 to the kickstarter that has a meshnet node in a box that's basically plug and play.
- benkillin 13y agolook at project byzantium - depends on a regular computer to use or a raspberry pi but the whole goal of the project is "plug and play" software that will allow you to at the push of a few buttons get an ad-hoc wifi mesh set up. http://project-byzantium.org/ http://project-byzantium.org/
- TaylorAlexander 13y agoDo it! As soon as we have the new hardware up and running we're going to play with mesh nets ourselves!
- jws 13y agoARM, IO pins, on board antenna. $30 adds an external antenna and battery charging circuitry. ISM bands, mesh networking. The chip they are using do 1200bps and 2400bps at low power, but the data sheets talk about 600kbps capabilities of the modem. I'd plan on the 1200 or 2400 if you are thinking 1km. Look to IEEE 802.15.4-2003 (Low Rate WPAN) for more information. (TI CC1200, or currently TI CC1101). They are aiming for strong cryptography. Keys are kept in a dedicated crypto IC. (Atmel ATSHA204) Shields planned for RC servers, LAN, and bluetooth. This could be my new favorite Arduino class board.
- swah 13y agoI thought Arduino = ATMega, is any ARM coming close in terms of power usage?
- stbtrax 13y agoArduino due is an ARM cortex m3 (microcontroller ARM). ATmega's aren't particularly known for their power consumption, you have always been able to get lower power ARMs.
- TaylorAlexander 13y agoThe plan is for it to be my favorite, and I'm designing it, so I hope so! I'm trying to design the system I've needed for years, because the problems I've had building robots generalize to nearly all the problems that Arduino users have. We are aiming to nail this.
- eterm 13y agoThis is the first time I've tried to back something on ks but sadly I've hit a wall, "us shipping only" on every level of funding. Can you add a tier for euro/intl backers? I'd love to see this product.
- jpitz 13y agoFor a KS with a goal this low, they likely aren't targeting anything but US-approved radios.
- Someone 13y agoHave you read the FAQ? http://www.kickstarter.com/projects/2021474419/flutter-20-wireless-arduino-with-half-mile-1km-ran#project_faq_66117 http://www.kickstarter.com/projects/2021474419/flutter-20-wi...: "Currently, Flutter only operates in the 915MHz radio band, which is US only for consumer electronics. Our boards support the few other bands used throughout the rest of the world, so we can design versions for Europe and other regions, but unless our campaign is well over-funded, we're not able to commit to international versions. Spread the word and maybe we can!"
- eterm 13y agoThanks, in my hurry to back I had not, I was going to say that there could at least be a t-shirt tier which didn't appear backable from the 'checkout' screen but actually it looks like it is, so I'll go for that. edit: Kickstarter is preventing me from getting the $25 t-shirt tier, asking me to say I'm in the US and otherwise looping back to the same page.
- TaylorAlexander 13y agoEeek, good catch! Now that the level has backers I can't change it, but we are working on a better plan for international backers, and I will contact Kickstarter and see if they can open up the shipping option on that reward! I'll post an update for international backers soon!
- oftenwrong 13y agoI wonder what the power consumption is like, and if it would be practical to run one off of solar power.
- agumonkey 13y agoExactly my question. I `dream` about an autonomous wireless mesh.
- TaylorAlexander 13y agoyes you absolutely can do this! We will have ultra low power sleep modes, and the radio can turn on briefly to send status, or listen in low power mode for remote communications.
- jstsch 13y agoIf you want something similar but simpler, take a look at the JeeNode: http://jeelabs.org/ http://jeelabs.org/ (Arduino+RFM12B)
- swah 13y agoOther advantages: already exists and costs 22.50 USD. (http://moderndevice.com/product/jeenode-v6-kit/ http://moderndevice.com/product/jeenode-v6-kit/)
- KaiserPro 13y agoand comes with an excellent set of libraries.
- TaylorAlexander 13y agoInteresting. Does our product not seem simple? We're working on some fancy mesh protocol stuff for making DIY projects easy, but those features don't have to be enabled at all. You definitely could use this just like an arduino with a radio attached, we'll have full libraries for sending data to any device directly, and our code will have copyleft licences (thinking GPL, haven't decided yet) and we will encourage forks. You can look at them as basically just compute and radio modules - they can be used however you'd like!
- jstsch 13y agoWith simpler I meant: something if you just want to do some RF within your home using Arduino. But Flutter looks very exciting if you want to do something more fancy :)
- vmarsy 13y agoAbout high range antennas, I'm more excited by the sigfox technology (25 miles/40 km range) : https://news.ycombinator.com/item?id=6285796 https://news.ycombinator.com/item?id=6285796
- bnejad 13y agoDoes anyone see what are the range differences between the two models? (basic and pro)
- TaylorAlexander 13y agoWe rated both as 1km max, but the basic will have an integrated antenna, with reduced performance. The current radio chipset theoretically maxes out at 3km though, and we haven't actually maxed out range ever, before maxing out distance (we have to use google earth just to find places!). Pro will have better range due to the antenna, but the basic will get a pretty high-performing antenna too.
- bnejad 13y agoThat pretty ambiguous. If they don't have the same range, then you shouldn't just ballpark them as both "1km max" because that doesn't really tell me anything.
- biturd 13y agoWhy are they able to be able to get so much more range out of this product than regular Wi-Fi is able to get?
- lutusp 13y agoMuch higher radio power level.
- TaylorAlexander 13y agoactually not at all, we have less TX power than most wifi devices. The data rate is inversely proportional to range, as is the frequency. We operate at a lower frequency than wifi (915 MHz), and a much lower data rate (your Arduino probably does not need a 100Mbps connection). This gets us range without blasting people with radio or having trouble with the FCC.
- lutusp 13y ago> actually not at all, we have less TX power than most wifi devices. Another post in this thread says 16 mw, compared to about 50 mw for an 802.11 class device, so that's rather low and I'm somewhat surprised by the range claims. I suspect the chosen antennas play an important part. > The data rate is inversely proportional to range, as is the frequency. Unless I have misunderstood the above sentence, it implies that the range increase as the frequency drops. In a word, no, because among other things, thermal noise increases as frequency drops. A low data rate will buy you more range, but range doesn't increase as frequency drops. > This gets us range without blasting people with radio or having trouble with the FCC. Maybe. It turns out that 915 MHz is a pretty busy area of the spectrum in many places -- successful communication might be harder in practice than the ideal case.
- rauar 13y agoLower bandwidth... and from one other comment they could be using lower frequencies as well.
- walshemj 13y ago
- nathan_f77 13y agoPerfect. Exactly what I've needed for a lot of project ideas.
- swamp40 13y agoHow come it says $20 in the title, then doesn't let you buy anything for $20?
- mryan 13y agoIf the KS is successful they will sell boards starting at $20.
- salemh 13y agoFrom the KS page: "Flutter Basic ($20) Still under development, the Flutter basic is tiny and simple. You get all the features of Flutter in a circuit board with an low-profile integrated antenna, rather than the large antenna shown in the video. Featuring micro USB for power and programming, components on both sides to reduce size, an LED, and a button, as well as plenty of digital and analog I/O."
- icebraining 13y ago"$5 shipping to anywhere in the US included."
- PStamatiou 13y agoI want to buy a bunch and build an alternate internet mesh network a la https://twitter.com/Stammy/status/372450697742008322 https://twitter.com/Stammy/status/372450697742008322
- gboudrias 13y agoIt probably doesn't have good enough range, especially through obstacles. Most of the nodes in our mesh use 15dbi antennas for that reason.
- outside1234 13y agoThis looks promising but two questions: 1. How do new nodes authenticate into the network? 2. Is it possible to get a USB version that could hook into a higher powered device, say a Raspberry Pi, that would act as the gateway to the internet for this mesh network.
- EdwCoady 13y agoCan someone explain how this is any different from electric imp or Zigbee.
- TaylorAlexander 13y agoI'll try! (I made it) Electric imp is Wifi and does not function without an internet connection (at least, thats what they told us at the first hackathon). It also doesn't function without a router. We're a lot closer to Zigbee - basically the same idea. We send data directly from board to board, unlike wifi which always runs through your router. We basically use every board as a router. The advantage over zigbee is price, Arduino, openness, and range. We have 10 times the range of $22 zigbee modules, and 5 times the range of their $50 modules, all in an easy arduino package. Does that answer your questions?
- AnIrishDuck 13y agoI see encryption everywhere in the pitch, but nothing about authentication. Doing a little research, the datasheet indicates their crypto module [1] does support HMACs. That said, I'm a little leery of a pitch that (a) doesn't appear to understand the distinction between encryption and authentication and (b) doesn't state they plan on providing both. Just my 2c. [1] http://www.atmel.com/Images/Atmel-8740-CryptoAuth-ATSHA204-Datasheet.pdf http://www.atmel.com/Images/Atmel-8740-CryptoAuth-ATSHA204-D...
- TaylorAlexander 13y agoHey there! I'm the designer of the product (and co-founder). Totally understand, we've been working as hard as we can to provide clear information, and I had a lot more written about encryption and cryptoauthentication before I realized it may be too focused (we want to get regular people excited about building projects). Cryptography is incredibly important to me, and my ultimate plan is for these boards to be useful in creating dark mesh nets so people can communicate freely even when others try to cut them off. The protocol will be lightweight and we support sending arbitrary data, so it shouldn't be hard to patch it into a network. I still remember the cryptocat articles from a couple months back, and the snooping from the NSA has turned me into a crypto evangelist, so I absolutely intend to provide real strong cryptography. I also understand how skeptical people are (and should be) about crypto systems, so as I'm still learning about this stuff I've been careful not to boast too much before I've got the exact system sorted. Currently the plan is full support for multiple master keys for different purposes (one for firmware updates, one for data, perhaps one for trusted guests, out of 16 total possible keys), per-packet session keys using AES-256, and I'm very curious about ECC, which it appears our system might support, since the encrypt/decrypt are software (though the new radio has an AES-128 hardware engine too). We'll give a LOT of detailed information on the development of this system as it happens (after the kickstarter). My plan is to design a system that any HN reader would be proud of. We're not going to "let open source do it", we're writing it ourselves and I've loaded my tablet full of crypto e-books so I can genuinely learn from the ground up how to do that. Even if ultimately I don't write the software, I absolutely will not sell a system as cryptographically secure unless I personally understand how it is built and why it is secure.
- chrisfarms 13y agoI want a UK one! Damn those poorly distributed airwaves. The EU allows the 136Khz band for amateurs I believe. It would be like communicating via semaphore in the fog and would probably need pretty large antenna, but we could be talking some serious arduino <--> arduino range... 50km+ I'd expect.
- leepowers 13y agoAwesome project. Reminds of SparkCore which was on KickStarter earlier this year: https://www.sparkdevices.com/ https://www.sparkdevices.com/ I wonder if it would be possible to wire an antenna to the Spark and match the 1km range of the Flutter....
- aray 13y agoSparkCore uses TI's CC3000 unit (http://www.ti.com/product/cc3000 http://www.ti.com/product/cc3000) which is a 2.4GHz wi-fi module. Flutter is using CC1001/CC1200, which are 900MHz radios. 900MHz (as a longer wave) will travel much farther to begin with, plus the module is designed for longer-range use :) (Also if you put a 900MHz antenna on a 2.4GHz radio you're gonna have a bad time)
- TaylorAlexander 13y agoYeah, they're in the same space as us. We hope that our range, low price, and extreme flexibility will really win people over. Wifi is not really a good protocol for Arduino. If you just want to send a few bytes (like "On", "Off", or sensor data like "215"), then wifi is across the board many levels more complex than is needed. Flutter isn't the minimum needed, but it's essentially the minimum needed to build a secure mesh solution. And unlike wifi modules, we have bare metal control over our radio chip, which gives us a lot more room for doing interesting things, like indoor 3D positioning (which we haven't tested yet, so I have no statistics on the accuracy... yet). The cool thing is, we will research indoor positioning, and every other use of this board we can. I think an open radio and computing module with encryption, long range comms, and ultra low power usage (sleep modes should allow for a year on a coin cell, though again, that has not been verified yet).
- chrissnell 13y agoLots of misinformation in these comments. For those dreaming of building a mesh Internet alternative, consider that these devices are not being designed for TCP/IP. From the looks of the KS page, they are going to speak a mesh protocol but likely something proprietary, perhaps similar to ZigBee, that is designed as a wire-replacement protocol for Arduino-to-Arduino comms. That's a long way from Internet routing. They are offering a WiFi shield but it's backed by the Arduino. Not really something that you want to mesh-route TCP/IP, in my opinion. There are more suitable choices. I'm also a little concerned about selling a device that is so high-powered by default. I'm assuming that they're using 900 MHz here. Is it really necessary for everybody to transmit with enough power to reach 1 km? In the US, there's a FCC rule that says that amateur radio operators use the minimum power necessary when transmitting. I'm not sure if it applies to a device like the Flutter but it probably should.
- TaylorAlexander 13y agoWe are definitely designing these to support mesh networks, and though I haven't written it down anywhere yet, we're not going to default the radios to full on, that will either be automatically configured (probably too difficult, but I'll look into it) or just manually specified. I would really love to make it automatic though, and for anything under constant comms they could easily communicate their signal strength in the ack if needed to coordinate that. The mesh protocols are still under development (that's what we need Kickstarter for!). Our wifi + ethernet shield makes it easy to have an always on device that routes traffic for home Flutter networks, but you can also just plug the board into your PC over USB and feed it traffic that way, you can run arbitrary data of any size over the link and all communications are guaranteed (or explicitly timeout), so I think piping TCP/IP over it will be easy. You can also use a raspberry pi and one of our boards to accomplish what the network shield does (for roughly the same price) but the network shield is designed for exactly this purpose, and many people will find value in that. It's tough to pitch an Arduino with lots of highly technical capabilities - Arduino users just want to know "but can i make a wireless beer brew setup?" That's the kind of information we try to speak to on the KS page. We're also still learning what questions people have!
- 13y ago
- TaylorAlexander 13y agoHey HN! I'm the creator and co-founder of this project. I've been designing robots since I was 15 and hacking on electronics since I could hold a screwdriver. What I think you'll like most about this project is the open source long range encrypted wireless link our mesh provides. I discovered Hacker News about a year ago and have been a regular reader since, so I remember Cryptocat, the NSA, and all the other things that reminded us why cryptography is important, and why implementing it is critical. So, a few answers: Yes, you can do encrypted mesh networks over long range. I'm a hardcore robotics guy at heart - the name "Flutter" was chosen exactly because this protocol is designed to be as lightweight as possible, and though the mesh protocol itself is still being developed (basically, that's why we need kickstarter, aside from the fact that I'm tired of ramen), I really intend for the protocol to stay out of the way. You'll also have full control over what happens, so you can always turn meshing off and use hard addressing. It's still really simple to use that way and cheaper than everything else I've seen that compares. I absolutely will not sell a product as "cryptographically secure" unless I believe it is, and I understand that the "smallest" flaw in a cryptographic system can render the entire system worthless. I am learning everything I can about cryptography, starting with some amazing e-books I have found on the subject, and just like wireless Our data rate is proportional to our range (this is generally true for any radio system), so we get 1km range at low data rates (1200baud tested, but we physically ran out of test room and had a strong signal). Theoretically this radio can do 3km at 1200 baud and it looks like we should be able to do 1km at 30kbps at least. Also I think the new radio chip doubles all the data rates in these cases (I would have to confirm), and I do know the new chip has higher transmit power and higher sensitivity, so range should be even better. There is a cheap radio amplifier (PA and LNA) called the CC1190, and texas instruments has all kinds of datasheets on using either of the two radios we are working with to give us 10km range, or much better data rates at 1km, etc. We're going to design the protocol with expansion in that direction in mind, if people really dig the range thing (it's a bit much for a beer brew setup, but if you want dark meshnets, lets do it!) I'm a hacker at heart. I first learned lockpicking at the old Noisebridge location (the original one). I love 3D printers and open source, did a rant/thread about open hardware on the Ultimaker mailing list a year back (I was one of the first in the bay area to get an Ultimaker too, and designed a new mount for it that I have on thingiverse). I got on hackaday for some 3d printed helicopter blades, and have been building robots since I was 15. There's a longer bio about me on our site, at flutterwireless.com See also me ten years ago talking about robots (and I feel silly for the "few people do" comment, but I was 15 and trying to keep it simple). http://www.youtube.com/watch?v=8FJu1eL_dYs http://www.youtube.com/watch?v=8FJu1eL_dYs Please ask me anything!
- tarekmoz 13y agoThe first app that comes to my mind is using those for a secured messaging protocol.
- songgao 13y agoLong distance is tempting, but it isn't necessarily a good idea. All kinds of wireless interference/collision will make available bandwidth really low. For example, on 2.4 GHz 802.11 protocols, there are 11 channels from 1 to 11. All wireless routers operating in US have to be on one of the 11 channels. When there are other wireless APs within the range, you and others share the channel. There's a limitation on how much bandwidth a channel can give in total. That's the hard limitation, given that CSMA/CA works well. That's why channel 3 and channel 8 often work great (most wireless routers have default channel choice 1, 6, or 11) - they are far away from defaults that others are using. Same thing applies to 5 GHz 802.11 networks. Now back to this project. 1 km is really long distance. You get communication range as large as a circle with radius being 1 km. There are a lot of wireless devices that fall in this range. You might not get affected by them since they don't have that powerful antennas, but your signals will effectively lower the bandwidth of all routers in the area.
- joenathan 13y agoFor 2.4Ghz only channels 1, 6 or 11 should be used as those are the only interdependent non-overlapping channels. http://www.cisco.com/en/US/docs/wireless/technology/channel/deployment/guide/Channel.html http://www.cisco.com/en/US/docs/wireless/technology/channel/... http://blog.saddey.net/2007/07/08/wifi-insights-why-you-should-avoid-using-channels-other-than-1-6-11-and-14-like-the-plague/ http://blog.saddey.net/2007/07/08/wifi-insights-why-you-shou...
- songgao 13y agoThat's interesting to know! Thanks for the link.
- SilliMon 13y agoWhat band is it using?
- TaylorAlexander 13y ago915 MHz ISM. We're working on international support. I made it, so ask away if you have any other questions!
- simonebrunozzi 13y agoThere's an Italian company called ForiniCom that built its own devices; they are around 40-50$ to produce, but they truly provide a Mesh network. Unfortunately it's only in Italian: http://com-com.it/ http://com-com.it/ I know they are managing more than 4,000 nodes now, and it works great. I also know that offering a service like this is hard. A kickstarter campaign sometimes makes things look too easy.
- TaylorAlexander 13y agoDon't worry, I know this isn't easy, but I don't like easy things, they're boring. My last project involved hand-winding motor coils for a linear motor I built from scratch, along with a 24v 10A per channel driver board & ARM CPU mainboard I designed and built. It was a pretty neat system, but robots are complicated, so I'm going to sell circuit boards for a while and dive into software development some more.
- Ecio78 13y agoSimone you can't compare the two things: they are an ISP and according to their tech pages it looks like they're using linux-powered devices in order to create an Hiperlan mesh network for internet access. It's like comparing.. a Raspberry PI with Telecom Italia/T-Mobile/Verizon deploying their own home routers for Internet access... You're also saying "offering a service is hard", Flutter is not offering a mesh service, they're trying to provide an Arduino compatible electronic board with long range wireless communication and with mesh and crypto features.
- gugol 13y agoHalf a mile is not a kilometer...
- cupcake-unicorn 13y agoSo this is really great, with the range, but I'm still looking for a decent wifi range, low powered wireless tag network. The closest I can find is http://www.mytaglist.com/ http://www.mytaglist.com/ , but I think the price is too high for the tags (used to be lower and then they jacked it up, on the hub as well), and they're creepily restrictive with their source code. The short lived GreenGoose looked like an option but is dead now. Anyone have any ideas of other solutions?
- tehwalrus 13y agoSuch a shame the first device is US only (although I understand why, regulation, etc...) I guess I'll have to wait until they hit a stretch goal for an EU design!
- thisthis 13y agoWhat happened to the claims of open source? Their github page ( https://github.com/flutterwireless https://github.com/flutterwireless ) is empty!
- kbart 13y agoAnyone knows what band is going to be used for wireless communication? And are there any plans for the certification in EU?
