My adventure in making a furry VRChat avatar move exactly as I do. This video isn't intended as a step-by-step guide, but more of an inspiration for what kind of things you can do. If you're interested in building SlimeVR trackers, I strongly advise following reference designs in the SlimeVR Docs, and talking to the community on their discord to get the most up-to-date hints and tips! Also if you want to see SlimeVR FBT in action, join the SlimeVR discord and drop into a community meet to see it live. You don't need your own tracking to join, all are welcome!
Bro builds his own VR body tracking units records it all to help us out and edits it and uploads it to youtube and then calls himself LAZY for not shortening power leads. We should all be so lazy! 🤣
I like that you added a video with non typical subject matter, but still about neat tech stuff. I’m here for all sorts of your content, be it board repair, builds, 2.5 hour Saturday “waffles” or neat stuff like this. Great work!
My guy. You have been "thee" most adorable and entertaining person I have ever seen surrounding Slimevr demonstrating capabilities. Your journey towards your genuine personal interest and satisfactictory outcome was to pleasant to watch. I found myself smiling at the end and wanted to say thank you for that wholesome ass moment. Keep being awesome!❤
This is incredibly helpful. All my parts to build my own set of slime trackers just arrived, and it’s nice to have video of almost the entire process uses reference, even if I’m not going as minimal as you did here. That said, to anyone else, that is considering this,find a friend with a 3-D printer and print some of the community designed cases. They make mounting, and assembly so much easier.
Imagine telling Alexander Graham Bell that in the future people will strap phones to different parts of their bodies so they can control a giant fox that doesn't really exist.
There would absolutely be so many scientists who turn to philosophy (have a mental breakdown) just because technology is building on itself without anyone bothering to learn how it works in any sort of depth. People not responsible for making cpus just know how to quantity it's speed and not why but we still skip several steps above that to do anything. We describe AI as learning instead of whatever goes on to allow that in its components. Even just general purpose computers where things aren't hardwired to happen in sequence. We haven't had to know that since they were invented and quite early on we started working on a level without actual association with reality. Even machine code makes something happen past making physics take place then we've got actual coding which has to be interpreted into machine code and applications which don't directly need any code to be inputted at all and are on a more human level like 3d model rendering. And it keeps climbing. Where will it stop abstracting from physical reality? I think I might very well be a historical scientist having a mental breakdown.
I mean any clockwork machinery can be explained in 2 levels. 1st is physics. 2nd these structures can be strung together to make more complex actions. It would be the same with hardwired "computers" at least.

Yea, using one for the first time did make me think 'oh wow... DIY IOT widgets are actually really easy if you learn some basic code...' Obviously there's a lot to the data processing for SlimeVR, but just making gadgets that record and report sensors is quite interesting.
I really enjoyed this. Not just because it was VR stuff, which I find fascinating, but because I really like the electronics maker community. You should definitely do more of it :D
i knew that slime vr trackers would be easy to make but i didnt think its really that simple. compared to many of my other projects this feels plug and play
more stuff in VR pleaseee, this is my main area of interest rn, I am a a 2nd year Electronics student and was planning to do some hardware project regarding VR for my individual project so having more insights and resources to look forward to is gonna be so helpful!! love your videos!!!
this video definitely helped me! i was having trouble understanding and knowing what each part does/is, now i understand and i’m sure that will make this easier for me!!
it was a delightful surprise to see you cover a topic that I have such a vested and special interest in; I lit up like a christmas tree when I saw the regulus, haha. excellent demonstration of the differing levels of tracker integration, and a pleasant build for the trackers themselves. would love to see more like this! 🐾
Thank you for this! I already knew about SlimeVR for some time, but your video is what caused me get around to making some! I made a 7+3 set and it works very well :)
whenever i have the money to get into vr i plan to make a setup like this, except with AA instead of LiPo batteries so that i can swap them easily when they die
Standard AA batts won't cut it, as they're 1.5v, not 3.7. However, I had the same idea and built another set of trackers with 14500 size (AA) Lipo cells. They're not very high capacity, but still enough for at least 6-7hrs use, and quick to swap out and put in a charger. Problem is that genuine 14500 cells are difficult to find. I'm not sure I'd recommend them, but they are still easier than having a massive USB charger that can handle 4-8 trackers at a time.
oh my god this is the exact video I've been looking for! ive been wanting to make a DIY full body tracking setup for my Rift S for nearly a year but I'm not knowledgable enough about the whole thing. This is a godsend!
I've always wondered if this was possible. You proved that it is. Great job. Can always be improved upon. Would actually love to see a video that is more in depth to learn from. Thanks so much.
Great Video and wonderful idea for my next project. I was just wondering what to build next and here you go. Keep going with VR content... you have two hands up from me. Take care
I absolutly want to see more VR content from you. Please make more. I am an avid VRChat user (and a furry) and want to see more of your projects on this.
There's a design for this called the OctoSlime, where you have a central pack with multiple extensions going to tracking points. I think the advantage is that the trackers themselves are super small because it's just the IMUs, and all the bulk is in one place, and there's only a single battery to charge - but the down side is that the system is less modular, one breakage means the whole rig won't work.
This was a wonderful video to watch and learn through. Wonder if there's enough amperage in a USB battery bank to power a bunch of these trackers, one single plug for the lot of them...
Possible. The TP4056 charges at 1amp by default, but you could mod them (programming resistor) to charge at, say, 500mA, and then have like, 6 charge off of a 3amp USB port 👌
i love playing vrchat i use index with 3 2018 trackers for fully body i do have a quest 2 and use it sometimes when i feel like just watching a movie or explore worlds that can be seen on quest and pc
hey, i see you have the PCB boards already separated, we got them in bulk and we have PCB boards still together with the cut lines marked/carved in. how does one go about splitting bulk PCB boards into separate PCB boards
What would be a fantastic idea is to design a motherboard or better still a flexi circuit that both board could drop onto and be soldered into place without the use of Kynar wire?
Yea there's lots of folks designing PCBs where you can just place the modules on and solder all the pins. They're probably the best solution, but also require finding someone selling them directly, or you need to order them custom.
@@Adamant_IT I only dabble and by no means have the facilities to design something like this. Plenty of online designers out there do though. I'm sure maybe a few on your channel as well? Maybe something to look into? It would save a whole lot of time :) This is a fantastic idea BTW Kudos to the original designers SlimeVR & owoTrack and you for bringing it to everyone's attention :)
I would love to see you build a FPV drone. It's an amazing hobby for the flying aspect, but the building side of things is fascinating. Especially when you start looking into things like the open sourced ELRS...
Nice project! However, the antenna of that module should hang outside of the device for best performance. The battery below creates a capacitive load that changes the impedance of the antenna a lot and "eats" its power and visibility to the outside world. BTW, why don't you use floor tiles or anything like it under the PCB that you work on? This way you could avoid destroying the mat. Cheers!
I used only steam base station tracking with vive as slime is great but wish it was more mass produced. Thanks I can see lots of peeps making their own slimes for a lot less I would not think that you would ever play vrchat that surprised me a bit in a good way have a good day mate
Is a VR headset necessary (if yes, would it work if I only use the tracker from the headset and not buy a VR headset?) or can I use another one of these trackers to replace the headset?
Headset not required. You can use Slimes on their own for other motion capture as well, either for 3D animation or for Vtubing, or for anything else that accepts BVR motion data 👌
I've not tried VR myself but I imagine it could be an amazing experience. There must be dozens of useful applications but I also think there is a downside in that people, especially children, lose touch with reality where there are real consequences to actions.
Your missing out dude. It has many different functions. An "immersive escape" from reality can serve it's purpose in VR with a social platform such the likes of VRCHAT. However, the intricacies of what can be envisioned and implemented thru the artistic flexibility of AR/VR, far outweighs the minimalism that is your primary concern. This will be very much be the building blocks of what we can expect from the future. Especially now that APPLE has finally arrived (fashionably) 3 years late to the party.
While I do show a full build-process for my trackers here, I didn't follow the reference design, so this isn't a great tutorial. It's more intended as a concept video to show ideas on what you can do. I'm planning to do a proper tutorial at some point soon though.
Wondering if this could be used to replace the head tracking on the reverb G2... I only use VR while seated but I’m really having trouble with the tracking... I’ve come this close to throwing it out the window... Imagine trying to do sim racing or flight sims and having to deal with the headset losing head tracking all the time 😰😰
I've just upgraded to a Reverb G2, but very specifically, the v2 edition with improved tracking. It's still not amazing, but it's not "broken". Arm tracking would help keep a body model in-line, but it wouldn't be useful to solve tracking issues in other games.
@@Adamant_IT Mine is a V1 but i was pretty sure the actual headset was the same... It's only the cable that's changed... And i upgraded to the V2 Cable with the button... Maybe my unit is defective or my room isn't really helping? idk... I just know its completely broken most of the times... I only use it for sim racing and flight sim so i'm always seated... I need head tracking only... Arm tracking wouldn't work at all in Assetto Corsa or DCS :P Thank you for taking the time to answer though ^^
It's a recolour of "Regulus" but there's currently no public version I'm aware of, the version I was using disappeared not long after I published this video.
When you were calibrating the sensors does it just want any six random positions or does it need to be oriented certain ways, btw your SSID and ip were visible in the logs.
The six sides of the cube. Not a problem if it's rotated, as it will always see one side pointing up, and be able to calculate everything else. SSIDs are temporary, it was easier to change my SSID for this video and change it back afterwards than edit it out, and an internal dynamic IP address is also worthless to an attacker.
It depends on where you're starting from. It's a lot like when a cook says that a meal is cheap, but they already have a cupboard full of herbs and spices, and all the tools. I usually tell people to assume $20 per tracker, to cover all the small costs that experienced people overlook. But if you have any electronic parts in stock, or you're willing to wait for slow delivery times from china, you can easily get it down to $10-15 per tracker. You realistically want at least 6 trackers for a 'full body' set up.
@@Adamant_IT yeah I was actually thinking of buying parts from China, thank you so much for the detailed reply! I will definitely use your video as a help as well whenever I should start building
Approximately how long to do your DIY trackers last for? Just little question I'd like to ask before making a decision of my own. I'll even take an estimate if you aren't quite sure, if you respond to this comment.
The rule of thumb is 1hr per 100mAh of batt capacity. The recycled cells I used in these trackers are approximately 1500mAh, so would give around 15hrs between charges. But I didn't bother testing them, so they all varied a bit. These days I'd strongly recommend using the Hyperion Lite or MeowCarrier designs, rather than building 'ghetto trackers' like I did in this video. But also this video was a learning process for me, and ghetto trackers still work, even if they're not very slick. I'm planning to do a modern build video for the main channel as a "I know what I'm doing now, here's the 2024 Slime meta" video, but in the mean time I have a playlist for my recent Hyperion Lite builds on the second channel here: th-cam.com/play/PLNlzgNQGNMEaPrzo8RAQbrHvridCzoNrN.html
@@Adamant_IT You are a life saver, I really appreciate you sharing all this with me! You see, I always dream to build my own trackers and implement my own artistic designs when creating casing for them. Making them more visually appealing. As well as improving my virtual experience. By all means, I’m truly grateful for your response, and thank you for taking a moment of your time to aiding me! 🙏
Hi Adamant or an viewer. Where do you get BIOS bin files? Any websites you can recommend. I bought RT809F and CH341A+ programmers just as you recommended to me when I asked in one of your videos. Now I am struggling to find bin files for different computers.
Not my cup of tea but interesting nonetheless. Thank you. Might knees and elbows be more useful sensor positions? As for batteries, how long would cheap CR2032 batteries last?
Maybe an hour if you have two of them in series... CR2032s don't have the current or capacity. The estimate for Slime trackers is 1hr per 100mAh of capacity at 3.7v nominal, so with CR2032s being 220mAh, 3v nominal, it'll be bad. I used fairly oversize cells, I think mine are about 2000mAh, but that means I don't have to do the recharge ritual after every single use. It doesn't actually matter where the tracker is on your limb because bones don't bend. So long as slime knows where your thigh is, it knows where your knee is, because the knee _must_ be on the end of the thigh bone. Incidentally though, once SlimeVR passes the 'virtual skeleton' data to SteamVR, Steam interprets it as Vive trackers on the joints.
Honestly i Think camera based system in the future will be the way to go so no trackers just have like 2 base stations like cameras with some AI + decent computation = win. Meta is already doing it problem is cameras on headset cant view full body and probably still a bit too much latency without controllers.
The resistor line is for battery level monitoring. You can remove the wire and the tracker will work, but you won't have any way of knowing when the battery is low. Nothing terrible will happen, but it might shorten the lifespan of the battery if it gets accidently deep-discharged often because there's no warning or cut-off.
I bought the stuff for slime vr but i got mpu 6050s because they were cheap and they drifted so much that i didnt even finish the rest of the trackers. I didnt really want to wait the two months to get new IMUs either but this kinda makes me want to lol
It depends a lot on how much extra stuff you already have on hand (equipment, hookup wire, connectors, etc) but purely parts only I'd estimate £10-£20 per tracker. If you buy parts from Aliexpress, you can push the price down to the low end of the bracket, but you'll be waiting longer and potentially have to buy extras that you don't need. 3D Printed cases I'm not sure the cost of, since I omitted them. If you have access to cheap/free 3D printing, that's going to keep the cost down too. Either way, this is probably the cheapest effective FBT solution on the market right now. Other methods that use cameras, kinects, that kind of thing are more proof of concept and can't get anywhere near Slime's precision. Vive can be more precise, but is also vastly more expensive.
Yes, no major changes to how you build and setup. Most of the slime updates are quality of life tweaks and improving the auto-proportions system. There's also a BMI270 IMU around now, and is likely to be the next weapon of choice for trackers, but support for it is still experimental, so BMI160 and BNO085 are still king.
Awesome video, and Very interesting. I've never thought I would see this coming about in real time, from the movies I saw that talked about VR as science fiction. Though how did you get the software to lip sync so accurately? Cheers.👍
VRChat handles it very well these days. An avatar has pre-set mouth positions for aa oo ch mm, etc, and the game animates them in real-time. I'm not sure if it's accurate to the actual voice, but it looks convincing enough 👌
As you probably already know, you could get those tiny battery protection modules without the tp4056 charging chip but with the voltage protection mosfet circuit. They sometimes solder directly on those battery terminals. They're cheap too, if not cheaper than those tp4056 charging modules.
Yea, I forgot to mention that most lipo cells will come with basic protection boards on them, but also I feel like it's bad practise to rely on those, or rather, you can, but it's not something I should advise doing...
Those things were cool and imho ahead of their time. Now however it's obvious they have been supplanted with better and cheaper tech. I've wanted to get one for a long time and tinker with it, never got around to doing it.
Heheh, yea little bit ;) This avatar was 'free' when I was using it, but it got pulled down. I think it was a premium base model that had been recoloured and uploaded as public, which was against the license for the base. Base name is "Regulus" if you want to track down a purchasable version!
Really great video! I really love your avatar too! Personally, I use SteamVR trackers, but eventually I may switch to IMUs. Line of sight for base stations has some drawbacks.

Arm tracking would help keep a body model in-line, but it wouldn't be useful to solve tracking issues in other games.
@@Adamant_IT Mine is a V1 but i was pretty sure the actual headset was the same... It's only the cable that's changed... And i upgraded to the V2 Cable with the button... Maybe my unit is defective or my room isn't really helping? idk... I just know its completely broken most of the times... I only use it for sim racing and flight sim so i'm always seated... I need head tracking only... Arm tracking wouldn't work at all in Assetto Corsa or DCS :P Thank you for taking the time to answer though ^^
33:00 I'm on this step right now and whenever I select it it says unable to connect to serial. Can someone help please?
Which avatar do you use in this one? it's great
It's a recolour of "Regulus" but there's currently no public version I'm aware of, the version I was using disappeared not long after I published this video.
Graham is slowly turning himself into a cyborg.
When you were calibrating the sensors does it just want any six random positions or does it need to be oriented certain ways, btw your SSID and ip were visible in the logs.
The six sides of the cube. Not a problem if it's rotated, as it will always see one side pointing up, and be able to calculate everything else.
SSIDs are temporary, it was easier to change my SSID for this video and change it back afterwards than edit it out, and an internal dynamic IP address is also worthless to an attacker.
Do you know the size heat tubing you used?
What was the mAh of the battery i got 380 2ould that be enough
how much did one tracker cost in the end? it looks amazing
It depends on where you're starting from. It's a lot like when a cook says that a meal is cheap, but they already have a cupboard full of herbs and spices, and all the tools. I usually tell people to assume $20 per tracker, to cover all the small costs that experienced people overlook. But if you have any electronic parts in stock, or you're willing to wait for slow delivery times from china, you can easily get it down to $10-15 per tracker. You realistically want at least 6 trackers for a 'full body' set up.
@@Adamant_IT yeah I was actually thinking of buying parts from China, thank you so much for the detailed reply! I will definitely use your video as a help as well whenever I should start building
Really enjoyed this....Keep it coming.
Approximately how long to do your DIY trackers last for? Just little question I'd like to ask before making a decision of my own. I'll even take an estimate if you aren't quite sure, if you respond to this comment.
The rule of thumb is 1hr per 100mAh of batt capacity. The recycled cells I used in these trackers are approximately 1500mAh, so would give around 15hrs between charges. But I didn't bother testing them, so they all varied a bit.
These days I'd strongly recommend using the Hyperion Lite or MeowCarrier designs, rather than building 'ghetto trackers' like I did in this video. But also this video was a learning process for me, and ghetto trackers still work, even if they're not very slick.
I'm planning to do a modern build video for the main channel as a "I know what I'm doing now, here's the 2024 Slime meta" video, but in the mean time I have a playlist for my recent Hyperion Lite builds on the second channel here: th-cam.com/play/PLNlzgNQGNMEaPrzo8RAQbrHvridCzoNrN.html
@@Adamant_IT You are a life saver, I really appreciate you sharing all this with me! You see, I always dream to build my own trackers and implement my own artistic designs when creating casing for them. Making them more visually appealing. As well as improving my virtual experience. By all means, I’m truly grateful for your response, and thank you for taking a moment of your time to aiding me! 🙏
Hi Adamant or an viewer. Where do you get BIOS bin files? Any websites you can recommend. I bought RT809F and CH341A+ programmers just as you recommended to me when I asked in one of your videos. Now I am struggling to find bin files for different computers.
I started watching this and was like i know this voice, but i wont tell.
Not my cup of tea but interesting nonetheless. Thank you. Might knees and elbows be more useful sensor positions? As for batteries, how long would cheap CR2032 batteries last?
Maybe an hour if you have two of them in series... CR2032s don't have the current or capacity. The estimate for Slime trackers is 1hr per 100mAh of capacity at 3.7v nominal, so with CR2032s being 220mAh, 3v nominal, it'll be bad.
I used fairly oversize cells, I think mine are about 2000mAh, but that means I don't have to do the recharge ritual after every single use.
It doesn't actually matter where the tracker is on your limb because bones don't bend. So long as slime knows where your thigh is, it knows where your knee is, because the knee _must_ be on the end of the thigh bone. Incidentally though, once SlimeVR passes the 'virtual skeleton' data to SteamVR, Steam interprets it as Vive trackers on the joints.
Honestly i Think camera based system in the future will be the way to go so no trackers just have like 2 base stations like cameras with some AI + decent computation = win. Meta is already doing it problem is cameras on headset cant view full body and probably still a bit too much latency without controllers.
Great video. Please keep the vide's coming even if it is not computer repair related :)
What is the battery output?
seeing this 7 months after release, might make slimes aswell
Do you need the resistor for this build to work?
The resistor line is for battery level monitoring. You can remove the wire and the tracker will work, but you won't have any way of knowing when the battery is low. Nothing terrible will happen, but it might shorten the lifespan of the battery if it gets accidently deep-discharged often because there's no warning or cut-off.
Thanks Adamant! 🤝
Im not really interested in this type of thing. But it was very interesting to watch. Thanks Graham.
I bought the stuff for slime vr but i got mpu 6050s because they were cheap and they drifted so much that i didnt even finish the rest of the trackers. I didnt really want to wait the two months to get new IMUs either but this kinda makes me want to lol
So many folks bounced off of SlimeVR because of MPUs 😔
BMI160 and BNO085 are a different world 😌
That was great fun, quick question if you bought the cells too how much would it cost per tracker?
It depends a lot on how much extra stuff you already have on hand (equipment, hookup wire, connectors, etc) but purely parts only I'd estimate £10-£20 per tracker.
If you buy parts from Aliexpress, you can push the price down to the low end of the bracket, but you'll be waiting longer and potentially have to buy extras that you don't need.
3D Printed cases I'm not sure the cost of, since I omitted them. If you have access to cheap/free 3D printing, that's going to keep the cost down too.
Either way, this is probably the cheapest effective FBT solution on the market right now. Other methods that use cameras, kinects, that kind of thing are more proof of concept and can't get anywhere near Slime's precision.
Vive can be more precise, but is also vastly more expensive.
@@Adamant_IT Thanks for the comprehensive reply much appreciated.
1:44 I saw lofi beats in the background
Does this still work with the current version of SlimeVR?
Yes, no major changes to how you build and setup. Most of the slime updates are quality of life tweaks and improving the auto-proportions system. There's also a BMI270 IMU around now, and is likely to be the next weapon of choice for trackers, but support for it is still experimental, so BMI160 and BNO085 are still king.
I was allready to watch you break dance 🤣🤣
What ended up being the final cost ?
Awesome video, and Very interesting. I've never thought I would see this coming about in real time, from the movies I saw that talked about VR as science fiction. Though how did you get the software to lip sync so accurately? Cheers.👍
VRChat handles it very well these days. An avatar has pre-set mouth positions for aa oo ch mm, etc, and the game animates them in real-time. I'm not sure if it's accurate to the actual voice, but it looks convincing enough 👌
As you probably already know, you could get those tiny battery protection modules without the tp4056 charging chip but with the voltage protection mosfet circuit. They sometimes solder directly on those battery terminals. They're cheap too, if not cheaper than those tp4056 charging modules.
Yea, I forgot to mention that most lipo cells will come with basic protection boards on them, but also I feel like it's bad practise to rely on those, or rather, you can, but it's not something I should advise doing...
Bouta build 12 of these bad boys 😈
It looks damn exciting. I'd like to know more about that
Those are some nice results! But Adamant IT vTuber board repair when?
An xbox kinect and driver4vr can do this too and many more.
You’re lucky you could build that your tracking is so good I wish I could do that:(
I'm interested in any thing that you put out.
Made that SMD resistor look like child's play lol
i wish i knew how to do this
The shame is that not many games use this in VR as of yet I have the Vive ones
crazy sick that is sew it in to a boiler suit
Super cool love it
i came back to finish the graham
When i saw the thumbnail i thought you were going to make something from a microsoft kinect camera.
Those things were cool and imho ahead of their time. Now however it's obvious they have been supplanted with better and cheaper tech. I've wanted to get one for a long time and tinker with it, never got around to doing it.
never expected adamant to be a furry, thats p cool
TP4056 modules cost so little... I bought 20 of them for under 4 usd WITH shipping...
i love how you desperately try to avoid the word "furry" lol
loved your video
by the way, is that a free avatar ? fancy a link ?
Heheh, yea little bit ;)
This avatar was 'free' when I was using it, but it got pulled down. I think it was a premium base model that had been recoloured and uploaded as public, which was against the license for the base. Base name is "Regulus" if you want to track down a purchasable version!
@@Adamant_IT well it is kinda sad that it was taken down, but I hope you found an avatar you liked!
It blows my mind that we can buy Arduino MCs WITH Wifi for less than $2
Really great video! I really love your avatar too!
Personally, I use SteamVR trackers, but eventually I may switch to IMUs. Line of sight for base stations has some drawbacks.
