DIY 3 AXIS CAMERA SLIDER | MOTORIZED CAMERA SLIDER

[@ChristophLehner]

Please note, as it is currently, the battery is not safe to use, as a fellow reddit user wrote: Please be aware that the lithium-ion battery you're using has *absolutely no* internal protection circuits, and lithium batteries can be severely damaged by draining them too low (around 9.5 volts for yours) or getting them too hot. "Severe damage" can, especially if done many times, can lead to the battery swelling or bursting into flames. Normally, the power tool has electronics that monitor the battery and will refuse to run the tool if the battery gets too low or too hot. Your setup has the opposite feature, where the buck regulator will work fine down to very low voltage, and the stepper motors will simply run with less torque as the battery drains to the point where it is permanently damaged. Your setup is unlikely to draw too much current at once from the battery, but I strongly recommend adding something to keep the batteries from being drained too low (over-discharged). The "correct" solution is a Battery Management System, a little circuit that goes between the battery and the electronics being powered. You can buy them inexpensively on [amazon] Alternatively, you could have the ESP32 read the battery voltage directly, or you could add a [volt meter] and run your slider with the understanding that you *really, really* should remove the battery when it gets down to 9.5V.

[@justanotherhumanlikeyou]

Any recommendations for what to use? I'm new to this and Amazon search (for me) returns solar battery management systems :)

[@full700kb]

Really REALLY well executed! I actually ended up here because I am working on a (kind of) similar project and am comparing different stepper libraries at the moment. Thank you SO SO much for sharing your code. You made a lot of really smart and inspiring design choices (using a battery pack for it - oh my!). Your editing skills are (almost :D) on par with your coding and MaschBau skills! Awesome work and thank you so much for sharing this with us. Subscribed!

[@SaikohTukay]

Dude, this is absolutely SICK! Well done!

[@themopeduniverse]

This slider is BOSS! Thanks for the video.

[@isaac879]

Awesome upgrades!

[@ChristophLehner]

But you did an outstanding job with the design,it's simple ,well thought through and easy to put together

[@samirale6774]

I made the entire slider, the only modification I have is that I am using TMC 2209 v3.0 instead of TMC 2208, and it turns out that the motors rotate continuously from one side to the other all the time, but when I move the joystick it does move Where I indicate it, what I'm getting at is that it never stays still, and the slide motor only rotates in one direction, the pan and tilt do rotate in both, what could be the problem?

[@hsnorh8180]

why i didn't discover this video sooner...😆 well done sir...👍 very good presentation...👍

I’m mentally almost done with my camera system, guess I’ll also be stuck for some time… Thanks for sharing your ideas and issues

[@MakenModify]

Great video. Many get the Hardware right but fail on the interface. This looks like a great implementation :) 👍

[@walterincardona4187]

I just love how you edited this video 😍😍

[@digitalbirdfilm]

Great work love the idea of using the PS3 controller.

[@mojomakesit6468]

It's so weird to see this video. I built essentially the same camera arm, also based on Attila's design and was also designing a slider to go with my 80/20 extrusion. I thought about using Issac's design and modifying it like you did, but ended up starting from scratch. My only regret is that I should have used three casters like you instead of four... Great project, well done!

[@ChristophLehner]

Hahahha what a coincidence. I upgraded my camera arm to 5 caster with a wider base, since it fell over onetime

[@mfx1]

Just a heads up an you may know by now but in the code you have lines that say thing like "slide_is_moving=true;" you can also get that value from the library with if(slide_stepper->isRunning()) note you can get a bit of drift if you ever decide to use closed loop stepper drivers as they can buffer some pulses so can carry on running for a short while after the library thinks they've stopped so you need to add a small delay to allow the buffer to clear.

[@randomprojectsxyz]

You are a legend. Thank you for sharing this.

[@samirale6774]

How did you achieve the connection between the esp32 and the ps3 joystick? I have the same joystick and I can't connect it!

[@GeekDetour3DPrinted]

Very nice project man! Yeah, sometimes, the secret is in the software! Congrats!

It were 6mm Plastic ball bearings. I don't think it will handle 4kg of payload, since it's not that ridigd. You are probablyy better off building one out off Aluminium

Absolutely brilliant work. May I ask where you used the 1xDC-DC Buck Converter for the ESP32 that you listed in the components but that is not present in the schematic.png posted on your github? I think I caught a glimpse at it at 6.24 on the right lower corner of the PCB but I can be wrong. Thank you.

[@ChristophLehner]

the buck converter is used from the 12v battery to power the ESP32 with 5V

[@louisroy3558]

Great video. I am doing something similar for a school project and your video has been very helpful. I have one question for you. Could you please tell me the specific versions of the libraries you installed on Arduino? Thanks!

[@xyzspec82]

[@DorfyBoi]

My guy, please tell us how you accomplished the 3 motors with different number of steps that are able to stop and end together. You don't talk about it at all and I can't figure it out or find anything online.

[@АлександрШевцов-ю4ц]

@Christoph Lehner , why do I need 6 magnets? Are they 2 pieces on top of each other?

[@mfx1]

A couple of other minor things since my last comment, there's a small typo in Serial.begin, it should be 115200 not 112500 also a way of setting a dead zone would be good as you can get a small amount of drift with the stick at centre particularly on older worn controllers.

[@triztoe]

Great work, thanks for sharing. What coding language did you use for this application?

[@ChristophLehner]

It plain old C++ on the esp32

[@elbarto919]

Hey Christoph, Great project!!! Are you planning on further improving the project (e.g. implementation of the hall-effect-sensors, more infos how you built the circuit board, more detailed parts list and the other feet you suggested)? I'd really like to built it myself but I'm not really into programming so I can't improve that myself. Since all the parts are about 200€ I'd like my slider to fully function if I built it, so it would be really helpfull and time saving if there'd be a little more info about the parts specs, wiring of the slider and dimensions of the circuit board :) Thanks in advance

[@ChristophLehner]

Check out the github link, in the description, there are the shematics and wiring diagram. I am afraid the development is complete...

[@gabrielwallinger3198]

hahaha.... I can soooo relate.... watching ToT, and building a slider with console-controller... I used an arduino and an NES controller, never got finished though...

[@mikelgomezdrummer]

Awesome! Im just building it! How do you get the ps3 controller and the esp32 linked?

[@ChristophLehner]

Via bluetooth, You need to tell the esp32 the mac adress from the ps3 Controller. I used an existing library for the esp32 to Connect to the esp32 and recieve the buttons.

[@proyectosbareloi]

Hello, could you help me, I don't know how to connect the Xbox controller to the Arduino. Could you tell me how you connected it or give me a link explaining how to connect it because I couldn't connect it and use it with the slaider. Please, could you help me?.

[@vex123]

Nice work! I'm hoping to build this as well. Can you tell us how much everything cost by the time you built it?

[@ChristophLehner]

It cost about 100€, most expensive part was the Extrusion

I need do this project but with an xboxone controller, how i can change to use this?

[@zaahirhamid8843]

Awesome video thanks for sharing.

[@philpavans3118]

Very impressive work. I would like to reproduce your project... I tried to copy the main.cpp in the latest arduino IDE and installed the two libraries FastAccelStepper and Ps3Controller. After a "verify" process I had a long list of errors concerning mostly those libraries, I even re-installed the 0.23.2 version of FastAccelStepper but I still got a lot of errors after "Verify". Impossible to copy here the log. Should I use specifically the libraries that are joined in your github folder and how ? Should I use another software than the Arduino IDE ?

[@philpavans3118]

OOOkkkkay I came to the conclusion that it may work fine with Visual Studio Code and PlatFormIO plugin .... results in a few weeks when I will receive the components

[@danieltorresblanco1053]

man you are my inspiration now... i cant sleep thinking about this proyect. But for my disgrace im from venezuela, and is a little dificult for me to buy the TMC2208. My question: Can i replace TMC2208 driver for A4988 drivers.. sorry im a newbie too... ps: forgive my english im doing my best!

[@ChristophLehner]

Thanks for the comment. It depends, functionwise it will be the same, but the a4988 are quite noise, so if you also want to record audio, you shouldnt use them.

[@Panals1]

The project looks very good and congratulations to its creator. I have drawn the circuit on a board and placed all the components. I uploaded the code to the ESP32, all the relevant leds (enable, step-led, the power levels on each driver) light up when I operate the joystick (SONY-PS3 the original one) but the motors don't move. They stay frozen in the enable brake. I uploaded the file with the Arduino IDE by renaming (not compiling) the (.cpp ) file to (.ino). The file loaded normally without the program giving me any error. On the serial screen the joystick seems to respond correctly. Is it because no compilation was done? Which I don't know how to do. If this is the case has a friend compiled the .cpp to .ino and can provide it to the community. Thank you very much.

[@ChristophLehner]

Well i think the issue is, you are missing the accel stepper library. You should try to get one motor moving first. You can also open the cpp file in text editor and copy the content.

[@Panals1]

@@ChristophLehner Thank you very much for the quick reply If you mean the library Fast AccelStepper.h I have installed it. I am also using board version 1.0.6 I also have to say that I have not connected the Hall sensors to the circuit and whether this affects the whole behavior of the project

[@АлександрШевцов-ю4ц]

Christoph Lehner, I have assembled a 3-axis slider that you have developed. When I don't touch the joysticks, the stepper motors move a little. What could be the matter? Or what to adjust in the program? Thank you in advance.

[@ChristophLehner]

It's probably the rest position of the joystick, if it's not perfectly 0, it will move the motor. You could add an if-statement, do block out any inputvalue from the Controller, under a certain trashhold

I never comment on KZbin videos, but this time is different. To anyone thinking about taking this up as a quick project - simply don’t. Everything about this is half assed. Starting with the “instructions” (if you can even call them so) and ending with the design. The instructions literally say ‘screw set’ instead of listing the screws that are needed for the slider. I guess pasting your PayPal link was more important than actually coming up with something worthwhile. 🤷🏼‍♀️🤷🏼‍♀️🤷🏼‍♀️
