there is a whole calibration process that happens BEFORE assembly. If you've not done that, and have anxiously assembled already, you may have to start again. Servos have limited movement range, and must be homed and installed aligned to start. There are a few videos specifically about this process in Nova's collection to guide you.

there is no documentation on size of screws - can you tell me which part(s) you are talking about? Most should be pretty obvious, I hope.

First of all thank you so much as I told you before, i am completely new to this things. If you are telling me that it is obvious it means that i have to figure it out measuring the fit of the screws 😅 by the way thank you so much for your answer and for the great work you are doing. Ps: sorry if i commented on other videos with the same request. @@ChrisLocke1969

unfortunately, yes, its a bit of guesswork with the screws. I don't think any are really critical lengths, but the receiving holes in parts should help you determine the length needed. Size of screw (ie: 3mm, 4mm) should be very obvious. If you run into any specific part / screw, let me know and I can look at Nova and tell you most likely. Good luck, and you're very welcome!!

check out the 3d assembly view, of which you can blow up and inspect all parts... maybe that will help a bit: novaspotmicro.com/parts-list.html

google would probably work better than randomnly making a mess of the comments section ;P

Feel free to ask specific questions, sure... otherwise there are 70 videos, a website, git repo, and discord channel to help you. Its a daunting project, so be sure you're up to the task first, and good luck!!

so glad it helped you, thanks for watching and pardoning the blurry camera work! ;)

yes, I scrapped both and eventually built my own remote for Nova... keep watching newer videos to see! ;) Enjoy!

JST themselves don't have designation of wire - so whatever device you're working on did it that way for a reason. I probably wouldn't do that without tracing each ground to be sure they are the same voltage line to start with. Otherwise, if they are all the same, it shouldn't be an issue to tie them together.

@@ChrisLocke1969 Thank you. It is to charge 3S batteries in a combat robot

for the final project, I used PETG for all of the black structural parts, and the yellow body parts are just PLA. Also, a tiny bit of TPU is recommended for the footpads, but not required. Checkout my channel, there are 70 videos detailing everything ;)

@@ChrisLocke1969 Thank you! I will watch them, and in your opinion PLA or PLA + would not be strong enough for this project?

@@Renfotzer you could get away with it, yes... but expect parts to fail and sometimes requiring lots of disassembly and rebuilding. Its not worth it, use PETG unless your printer doesn't support. PLA is just too brittle... PETG has more strength and is more flexible / giving.

@@ChrisLocke1969 Ill just use PETG then, thanks for the advice!

glad it was helpful, and thank you for being kind about the focus issues - I wish I could replace this video, but youtube doesn't let us :(

unfortunately no, it has no IK, its all scripted movement, sadly. If you or anyone you knows has that coding capability, I'd be happy to work on it with them! :)

@@ChrisLocke1969 I could help, but you just need to explain your script. How it works. The rest is mathematics. AutoScript...

@@robn2497 ya? ok, maybe email me and we can work together on it a bit? Too much to explain here lol cguweb at gmail

@@ChrisLocke1969 Never heard back from you, you ok?

Nice catch! But shhhhhhhhh :) lol

Welcome back!

My pleasure!

Glad it helped, despite the blurry video ;)

practically non-existent. the coolest part I will show in an upcoming video - the software control of these motors is unreal - every parameter you could imagine. Impressive.

thank you, kindly!

that's a good question, according to digikey -it says "the mating housing has crimps", but doesn't say much about attaching wires except "have poke contactors", which sound to me like just wiring piercing connections, like a ribbon cable maybe. Sorry I don't know anything more about these particular JSTs: www.digikey.com/en/product-highlight/j/jst/sh-and-sr-series-connectors

nah... they are cheapo $30 servos

35k views, I can handle apologizing again to the few you who cared enough to mention the focus problems. All apologies. You could also help us creators by contacting youtube direct and ask them why creators aren't allowed to edit or update video uploads, then this issue wouldn't exist along with many others of different types. We try, thanks for noticing. ;)

Well said.

sure, you can use whatever technique you'd like - the JST connectors just make it easier to remove the head, tail, and top covers when needed. But if you are using the PCB, it may not be easy to skip using those JSTs, unless you're going to solder directly to JST pads on PCB.

the thermistors was the last piece of hardware I was working on, but never completed, so you won't find any code on github for them, nor wiring. I never even got to the point of integrating them with Nova, still on a breadboard, sorry.

and good luck with your build! join discord if you haven't, lots of great helpers in there if you get stuck any where.

Aha ...ok....thank you for your answer....i think i van start soon. Ordering things first and then.....HARAKIRI...😅👍...or something like that...😛

can*

awww... yes, I had trouble with Green Terrors and bladder disease, as well. Same process, Quarantine it if you can, add Magnesium salts to water and stop feeding dry food. Slightly warmer water temp can also help. If you can feed organics, like peas or frozen fish, that'd be best. Then hope for the best!

@@ChrisLocke1969 I have him an epsom salt bath yesterday and now tonight I'm setting up a 20 long hospital tank. Question, should I use epsom salt in the hospital tank and how much? Thank you for answering by the way this is my first time having a fish with this issue in 5 years of having these guys! I got them all when they were lil minnows lol

@@wisconsinaquatics hopefully on the way to recovery. Yes, continue the sakts, however, remember salt doesnt evaporate, so every couple days, do a 30% water change, replenishing salt. The amount is debateable, i wouldnt do anymore than a tablespoon per 5 gallons.

that's exactly what gave me the idea!! :)

lol I wish... and that would surely be my top video if it could. Not possible with servo motors regardless.

And walking slope and other inclined surfaces

@@tiagoferreira1169 I think you're expectations may be a little too high for projects at this level, my friend. Its definitely more of a research / concept model than a functional robot.

Sorry i just want to use it as a guard n attack hound by puting a homebrew nerf blaster

and i think my that uses raspebrry pi can walk slopes if i try hard

y splitter? do I do that somewhere? lol the hood sensors maybe? Anyway, all you have to do is splice the wires, not try and get multiple wires into the connector pins - that's not possible.

I suppose it could, doesn't sound that heavy or large.

that'd be a great idea, though I haven't given it much thought beyond some vision capabilities, perhaps.

could very well indicate swim bladder disease. This could be from a number of things like water quality, age of the fish, but most commonly their diet. Watch my previous video on the topic for more help and good luck!

It has an IMU that provides the data needed. I have implemented one balance mode, but not integrated with any walking gaits.... yet. ;)

sorry to say, that was pretty much the last progression of the project. There are a few hardware things I would still like to finish, and obviously improve the walking gaits... otherwise, if you made it this far, shouldn't be a huge challenge to attempt at polishing it off in your own ways.

Thank you for the kind words! Enjoy your robot!!

referring to the diagram, R1 and R2 are for Button 3 and 1 respectively. R7 is 2.2k and R8 is 1k. The code for the battery voltage is on the teensy in the main code, have a look at the battery_check() function github.com/cguweb-com/Arduino-Projects/blob/main/Nova-SM3/Remote%20Control/Wiring/Schematic_NovaSM3_Remote_v1.png

@@ChrisLocke1969 so the voltage divided should be using 2.2k and 1k resistors? The broblem is that in the diagram the divider is connected to a wire coming from a button, and its connected before the pulldown resistor so 1k resistor of the divider is in series with the pulldown resistor. Making it basicly 2k resistor in the voltage divider circuit

@@TheSaukkio incorrect... 1k resistor is sent to ground (that yes, is connected to button, and every other component in the system). Please refer to the diagram and the correct resistors pointed out in my last comment.

the ACS712 was removed from the build back at version 5.0 - its in that diagram if you're still interested in implementing it: github.com/cguweb-com/Arduino-Projects/blob/main/Nova-SM3/Wiring/5.0/wiring_diagram_teensy_v5-0.png

this diagram shows the NRF wiring: github.com/cguweb-com/Arduino-Projects/blob/main/Nova-SM3/Wiring/5.3/Wiring_NovaSM3v5-2b_pictogram.png the address will depend on your situation / environment. In most cases the default will work, but it may interfere with the OLED. I set mine to the max address, don't recall offhand, but its the less commonly used address.

Well there it wass the whole time 🤣🤣 thanks again for saving me

its a big project, I'm glad your navigating it pretty well considering the holes in my documentation ;)

correct, it is not time, but the PWM signal that the adafruit PWM Controller board expects. Its dependent upon the frequency setup in the driver. learn.adafruit.com/16-channel-pwm-servo-driver I just used the setup they suggested for servo motors, so the range for 180 degrees turned out to be around 150-650 for min-max, but even less for Nova with mechanical constraints. Hope that helps.

Thanks. This explains it😁

thanks, and as was your late-to-the-party comment, since I apologized and explained in both the video and description and comment section.

email me and I will share it with you

crud, I guess I never got around to making Part 2, sorry about that. There are a couple of older videos reviewing the software, hopefully those help: kzfaq.info/get/bejne/rsxohMeq0sWckas.html kzfaq.info/get/bejne/eZhjdribv9fVo4U.html

@@ChrisLocke1969 thanks ..

quarantine if you can, add 1 teaspoon epson salt (no additives like perfumes!) per 20 gallons of water, light feedings, try frozen peas, and the cleanest water / frequent water changes is about all you can do and hope for. The alternative is surgery (ie: poking a syringe in their belly to degas their bladder... not something you want to try without a professional, though. Good luck!

these videos may help a bit more: kzfaq.info/get/bejne/rdt5o5pquM6uoIk.html kzfaq.info/get/bejne/iqd3htiIv92nl6M.html

you remember correctly.... and made me realize its buried in an unrelated video... that's surely messing lots of people up. Ooops. But here is what you were looking for, if its not clear, let me know, I will shoot another video and post it asap. kzfaq.info/get/bejne/fstgns2a0Jydl40.html

@@ChrisLocke1969 Thanks. That’s what I needed to see. This may be a big ask but is it possible to number or show the dates the videos were posted? I would really like to see the whole project.

that's an easy ask... if you go to my channels videos page, you can sort them by popularity or "latest". Yes, that'll be the opposite sort order you're asking for, but I cannot control the sort order anyway, so just start from the bottom up, there are about 70 videos, I believe... many of the first ones are nova SM1 and SM2, which are still partly relevant, but as you probably know, the microcontrollers, remote control, and other things changed along the way. Hope that helps!

@@ChrisLocke1969 Thanks again. I’ll get busy.

yes, I realize that and apologize. I wish youtube would let us edit / replace videos - I would reshoot it. :( To "fix" it, I would have to repost a new video and delete this one - I'd rather not do that. :(

@@ChrisLocke1969 Understandable. I always wonder why they don't allow it. Perhaps because they fear that misuse would ensue.

I'm not an expert by any stretch of the imagination but enjoyed your video and agree about the focus. I note the black dimensions on the die were in focus the entire time. Maybe a small silver object against a black background might be better for focus because of the contrast? Only constructive criticism as I loved the video - was exactly what I was hoping to find and found your presentation/time excellent. Looking forward to future videos.

This is much more concise and in focus... kzfaq.info_zl28E2urEU

yes, most components are larger / higher capacity in larger servos, including mosfets, coils, and even gears and bearings to support higher voltage / currents, and obviously to create more power / torque. I am playing with 12v 150kg servos currently, they're quite fun!
