We recently learned that Tindie suddenly blocked sellers from Ukraine, so we can't sell anymore. That's why the shipping options don't work.
So we reopened on Etsy: Ultimate Robotics Etsy Shop
Here's the link to uMyo: uMyo on Etsy
Sorry for the wait and thanks for being so patient!
New (small) batch of uMyos is in stock while we wait for a bigger one!
New batch of uMyos is in stock!
uMyo v3 is officially out and in stock! It is now smaller and has separate battery charger. Release notes:
It's a first ever open source hardware wireless EMG wearable device with hybrid wet and dry electrodes - as far as we know of. We've been working on uMyo for some time, and we know a lot of people have been waiting for it. Well, the wait is finally over! You can read more about uMyo development on our Hackaday blog. It's also our second device that we will be selling, besides uECG.
There were open source EMGs before (most prominent example is Sparkfun Myoware), but they weren't wireless, which is absolutely critical for signal quality. And there were wireless EMG devices (like Myo Armband), but they weren't open source. And none of them had possibility to work with dry and wet electrodes on the same device.
One uMyo device is a single-channel EMG. It's lightweight and inexpensive, and it's also modular - you can combine several devices and get multi-channel EMG. It can be used as a development platform for projects using muscle signals, for research, rehabilitation, or to control things on a computer or in the real world. It would be most useful to researchers and students, makers and hardware/software developers, and medical professionals, especially the ones working with physical therapy.
We are launching sales of another 50 devices.
First orders may be shipped with a slight delay, but normally we will try to ship them within 3 days.
The pricing can change a bit on further batches. It can go up or down, but we do not expect it to be radically different, as our goal is to make uMyos affordable. Our priority right now is that everyone who has been waiting for a new EMG sensor for their projects could get a device (or two) to test and experiment with. You can actually order up to 3 devices, and we even lowered base shipping rate for that, primarily because of Europe customs limit, but also for the rest of the countries. However, for testing purposes it would be best if more separate people could order and experiment the devices. And also, we don't really have tutorials for multiple devices yet. So it's best to only order 2+ devices if you know what you're doing.
Please don't order more than 3 devices to Europe, as this will go over 150 EUR customs limit! If you do that, we will refund the order, as we can't ship them for now. For UK: additionally, please don't order more than 2 devices to the UK, as only EMS shipping is available to your country and shipping with it will go over the customs limit. Please read general disclaimer about Europe below.
Feedback: We have a Discord server! We will be very glad if you share your projects and feedback there. Also, you can receive support from the team and community there. If you don't have Discord, you can also contact us here on Tindie, on any of our social networks (links are here), or by email: firstname.lastname@example.org
Disclaimer about batteries: uMyos are sold without the lipo or CR2032 batteries! You can use ones you have at hand or buy a new one from somewhere. You'll want the ones with 2 mm JST connectors - we have some product links on this Hackaday post. Because of this decision, we were able to lower the device cost and sell it to you cheaper, and it greatly simplifies the logistics. This is because we have to ship batteries to us by sea and it's very slow, and then there are some issues with shipping them to buyers by air, because postal services don't like to ship batteries inside packages, especially more than one. Besides, a lot of people already have lipo batteries at home from other projects. Also, as of v3, you can power a single uMyo from a CR2032 battery. They're easily available and you can test uMyo with them until you get lipo ones. One CR2032 can last for about 3 hours of testing.
Disclaimer for buyers from Europe: 1) You'll have to pay VAT when receiving the package. Tindie doesn't have IOSS yet (like eBay, Etsy and other major platforms), so we can't collect VAT when you order. Sorry for that! 2) For now, please don't order more than 3 devices to Europe so the total order (including shipping) doesn't go over 150 EUR. We adjusted the prices so 3 devices can still fit, plus shipping. Also, because of that, we currently only offer standard air mail for Europe, as to not go over the limit. It should be still rather fast these days, at least until New Year.
Disclaimer for buyers from the UK: The above rules about Europe apply. Additionally, please don't order more than 2 devices. Because standard air mail does not track reliably for the UK, we can only ship to you with EMS, and this will make the order amount go over 150 EUR limit.
Sorry for all of the limits! Hopefully it will change in the future, but we have to set them for now.
If you're not from Europe, proceed normally.
Now that the introduction is over, here's more details about the device!
You can either order uMyo full kit with a bracelet, or just uMyo, or mix those two options. If you want 1 uMyo kit and also want to add some more separate uMyos, make sure to put them into cart one by one! You can also buy 2x or 3x devices kits. If you order several 1 device kits, we'll make sure to put them into separate boxes in case you need them separately for different people, for example. Otherwise, it's cheaper and easier to buy 2x and 3x kits if you need more than one uMyo.
Standard kit includes:
uMyo only includes:
Bracelets: 25x380 (longer) option is for average and larger arms, 25x290 (shorter) is for smaller arms. Smaller arms are roughly the ones around 25 cm (10 inches) and down in circumference if you measure right below the elbow. If your circumference is over 25 cm, probably choose the 380 option. We didn't know how many bracelets to get of each color, so we're testing for now. We're very interested to see which ones you like! The smaller bracelets don't have orange color cause our supplier run out of them suddenly.
If you're adding into cart "Just uMyo" option, please also choose "No bracelet". If you forget to change it, don't worry, in this case we'll just not ship it. We can't change the bracelet options automatically depending on kit unfortunately, sorry for that :(
Looks like that's it. We're excited to see you test uMyo!

We recently learned that Tindie suddenly blocked sellers from Ukraine, so we can't sell on Tindie anymore. That's why the shipping options don't work.
So we reopened our shop on Etsy: Ultimate Robotics Etsy Shop
