Thanks a lot, I designed this just to involve more servos to the models, so I could show the capabilities of the bechele animatronics software. Building the lips involved a lot of manual steps to get the flexible rubber bellows. The core of the bellows was 3D printed, but applying the rubber milk using a brush was a manual process.

Hello, I admit, that it may be a little tricky to put all parts to the right place. If you have a CAD program, you may load the file Demohead.stp into it. Then you can see, where which part belongs. The zip file (demohead.zip) containins all parts and also the stp file (all parts mounted). You find on the following page: bechele.de/?p=1206 If you have no CAD Software, you may download and install FreeCAD: www.freecad.org Another source of Info how things are mounted is the video: ruclips.net/video/Qj-uKgw153A/видео.html. If you cant get ahead, just drop me a line and explain in detail what you need to know, so I can try to explain. Keep in mind, that the demohead I just made to show the capabilities of the bechele software. It was initially not intended to be shared, but because people asked for it, I decided to publish the parts for 3D printing. The red lips for example are out of red latex rubber I applied with a brush in serveral iterations onto the waxed "lip core".

@@Bechelede Thank you! the STP file did help a lot and I managed to identify most of the parts. I'm left with one part - 'Upper Jaw Axis' which I couldn't figure out where it should go, could you assist me with that?

One more question,,,,, regarding the 'latex_lip_core' part. I couldn't quite understand how it fits in. the CAD model file itself is a bit different from the one that is demoed on the videos (it has kind of a rectangle 'stand' which is not showing on the videos), and it is not clear how the lower & upper lip pieces connect to it

Sorry for the late reply. The upper jaw axis is the rotation point of the upper lever (jaw) where the upper lips are mounted to on the ouside. The upper jaw axis fixes the lever on the inner side, so the upper lips can move up and down. The rectangle stand I just made to prevent the heads from jumping around on the table. Some heavy weight on the stand would do the same job.

The lip core is just a form for the latex lip. After applying about 5 to 7 layers of latex milk, and complete drying, the lip needs to be powdered using french chalk or baby powder. After that the rubber lip may be stripped from the core. Two of the lip halfs may be glued together with a little latex milk. After drying again, I cut a hole in the middle (glueing point) of the lips, just large enough, so the front of the jaws fit inside. Then I put two small (4 mm diameter) glass pearls inside either tip of the lip. The pearls make sure, the lips do not slip out of the mouth edges during movement. Then I applied two more chain pearls onto the jaw lever ends. After carefully pulling the lips through the hole I cut into the lip middle over the jaw lever end and the applied pearls, the lip middle is fixed to the jaw. Because the lips are out of rubber, they can be stretched an squeezed as the levers move.

This makes me happy. If you need support, don't hesitate to contact me. Software and further information you will find here: bechele.de bechele.de/?p=814 bechele.de/?p=1053

Thanks a lot, It makes me happy you like it.

Thanks a lot. As indicated in the video title, this is just a demo of the bechele animatronic software. What would you like to see in detail ? Software details you can see on my web site: bechele.de and on my youtube channel: m.ruclips.net/user/Becheledevideos

Well, actually the model was just intended to show the capabilities of the new bechele software. However if there is an interest for the CAD data, I will publish that also. Please give me a few days time to prepare everything to make it "Public proof". By the way, the plate in between the two heads is just to make sure the models do not "jump" around on the table while moving ...

Today I published the puppet head model on Thingiverse: www.thingiverse.com/thing:6545436 In case of questions, don't hesitate to contact me.

Dear Jadson, many thanks for the question. Unfortunately that does not work, because 1.st The bechele software only runs on linux and 2nd a PC does not provide an i2c interface, you could connect an i2c PWM device to. So you need a computer that runs linux and that provides an i2c interface. Further to use all functions, the GPIO device of a RaspberryPI like mini computer is required. Many of the Boards listed here could run the bechele software: www.armbian.com/download/?device_support=Standard%20support&arch=aarch64 However, if you want it easy, I recommend to use whether a RaspberryPi 1b, RaspberryPi 3b or an OrangePi-PC, because for these boards exist ready prepared SD Card images. If you want to stay with PC, perhaps this Software may help you further: github.com/knee-koh/MarIOnette Both bechele and MarIOnette are open source. Bottango for example also runs on a PC, but the license is restricted to beta use for free. I guess one fine time the software will be sold ....

In case of trouble, let me know. I am curious to see your project - if you want to share.

@@Bechelede i would love to share my project with you, hoping you will be able to help me with it and installing the software and getting it up and running, im pretty good with hardware work, but software work i struggle on, maybe we could somehow have a call?

Why not, in which time zone are you located ? I am living in germany. In the impressum of my home page bechele.de you will find my mobile phone number. WhatsAppp would be another option.

@@Bechelede Thank you, my time zone is GMT, i live in the United Kingdom, i think WhatsApp would be better as i can send photos and videos easier, i will install WhatsApp and get back to you, thank you again!

You are welcome to contact me in either way.

Well I noticed, there was a need to explain the project better.

yes, the images contain all files needed - have a look at the following how to install: bechele.de/?page_id=1069. Hope you have fun with it.

@@Bechelede thank you, i noticed this website after i had made the comment sorry about that, but it looks a lot more complicated to the previous way of putting the image onto the sd card, my sd card is 32gb and is FAT32.

How the SD card is prepared is unimportant, because an image writer just copies all - including formatting. After installation of the image not all space of the card is in use - only about 2,5 to 3GB. Only if you want to use the rest of the card it becomes a little more complicated. But for starting, there should be enough space left on the file system. So increasing the file system size is just an option.

@@Bechelede Thank you, i already have a few test speeches and music mp3 ready that are abount 2 to 3 minutes long, would there be enough space for that? Or would i need to increase the file sisze? Also how do you put the mp3 audio on the sd card? Thank you again!

@@Tamla1959Sure, the file system (depending on which image you use) has still at least 350 MB free space. Two MP3s of 224 Kbit/s @ 3 minutes have perhaps 15 MB and the servo movement files are far smaller. So you don't need to worry about the space of the minimized file systems.

Thanks a lot for your positive comment

Yes, the code is available here: bechele.de/?page_id=73. The code is available as a tar ball, as a raspi image or as a OrangePi PC image.

Dear Simobomb6475, many thanks for the question! Yes, I have seen it already, it looks to me like animation in blender. I think it is very similar to blender's animation function. Probably it derives from that (that is just my guess). It is certainly a very nice project. However the approach is completely different, With bottango you define movements based on positions and movement curves from one to another position, but doing animation this way is quite time consuming: Assume you have a 3 minute clip ( a talking or singing puppet) and you have just 5 servos. And further assume you have just 3 movement changes a second, then you have to set 5 x 180 * 3 = 2700 curves to set. If it takes you just 10 seconds per curve, it sums up to 27000 seconds = 7.5 hours to set up a 3 minute clip. Using a joystick and my software it takes you only about 30 to 40 minutes to get a ready made animation for all five servos. This little calculation does not include the need to syncronise to music and the movement and the numberless repeats in bottango to see if all appears fluently fitting. The bottango demo video only shows the creation of a five second movement and therefore already needs two minutes, although it is clear that the demo video is a condensed view. My software does not claim to compete against such "huge commercial projects", but offers an easy to use, fast and open source alternative if you need to synchronize movement and sound. The "old mac donalds song" animation for example, took me about 1 hour to set up and the yellow head has 10 servos!

@@Bechelede nice

Let me know, if you need any help.

For my humble opinion it is not really worth to repair the unit, since you can get a new one for little money. Also there is not much you may do apart from checking if the contacts are proper. The chip is directly bonded onto the printed circuit board and covered with a droplet of sealing material.

Dear Andrew, the current software version allows to use a joystick, whether a self made or a standard USB joy stick. see: bechele.de/?page_id=82 and bechele.de/?page_id=73 In case of questions, feel free to ask.

If you look at my channel, you will find some: www.youtube.com/@Bechelede/playlists Further information is also available on Bechele.de: bechele.de/?page_id=70. In case of questions, you are welcome to ask.

unfortunaltely the Software I wrote only supports PCA9685 PCBs that are connected to the Raspi pin header via I2C. The Software could be relatively easy modified to allow several PCA9685 boards to support more Servo channels (currently 16), but I did not realize this up to now. The board you use, is surely quite good, but the price is at least 10 x the price of a PCA9685 PCB

@Bechelede thanks for getting back to me the board I have I paid 34 dollars which isn't bad but I didn't know what else to choose at the time. I was planning on using two of them because. I have 4 characters between the 4 for characters in total for 4 characters will be 40 servos and and sssc32u just one of them can hold 32 servos just in need now for a programming software. I currently almost have one of the 4 characters almost built and ready to start setting and testing servo movement and programming the movements. If I can't use my current board with your software. I'm very open to any suggestions to be able to use your software im looking forward to bringing these characters to life and watching them perform for the first time.

As you can see in the video, the teaching process to record the movements is quite simple. However currently you can use only 16 channels per RASPI. I think the decision which way to go is something you have to figure out. For all the software in my project you can modifiy the sources as you desire and all is free according to GNU V3.0. If you run into trouble I can give you one or the other tip. Perhaps you have already seen my web site: bechele.de/?page_id=70 I recommend to read the readme from the software package for more details: bechele.de/?page_id=188 I would be glad if you'd have a closer look, if this is sufficient for your purpose. However keep in mind, that this is a non commercial private project, so support in case of problems may be limited by the fact that this is just a hobby for me.

just re watched the video, and found link to software, thank you, if i come across any problems ill let you know, thanks again.

You are welcome to contact me, in case you need support.

@@Bechelede thank you, as it turns out, im just setting up the joy stick, but i cant seem to get it working correctly, in the joy stick arduino code its middle point is suppose to be 512 on both axis, but the joy stick keeps slightly shifting from 400 to 500, i think it has to do with noise, any idea on how i can fix this, reply when posibble thank you.

@@Bechelede hello again, i cant seem to find where you explain how to wire up the PCA9685, and i dont have a longer ethernet cable to connect from my raspberry pi to my router, what should i do?

@@Bechelede sorry to bother you again, but im having trouble understanding what i need to do, i have got servers the raspberry pi and the arduino, and the servo board, but your website looks very complicated and im having trouble understanding it, could we have a chat or a call of some sort, i really want to make this robot but i need your help with it, reply when posibble thank you.

Yes, the STL for this is available here: www.thingiverse.com/thing:5339697 Also you will find an OpenScad file, that enables you to customize the hose diameter.

@@Bechelede Tried to tip you on Thingiverse but your not set up until then I guess thanks will have to do. Thanks

Well, as I wrote on my web site, i disabled tips, because I take my efforts as a humble contribution to the community, and this needs no "tips". Thanks for the good intention anyway.

The tip function is blocked by purpose, but I am always happy to see, when one of my designs is appreciated. Many thanks!

Thanks a lot - have you seen the new software version ?

@@Bechelede I havent. Can you send me a link? Id love to see it! Thanks J

Sorry for not responding sooner, what does this mean ? I know FNAF as Animatronic puppets - do you need any support ?

@@Becheledeirl means in real life and im not sure if your dissing me

@AFKTheKing90 Sorry dissing was never in my mind. Keep in mind I am german so I did not understand the abbrevation. Thanks for clarifying.

Hello, the first question is easy to answer: That is what the software is made for - see: bechele.de/?page_id=73 The second wish is not so easy to realize, since sequences are usually started by a button press, so you need to find a way to trigger the movement sequence and even more difficult the voice needs to be translated into senseful movements . I think my software is not the right thing for that.

Gute Frage ! Die Primer kann man bestellen. Einfach nach Cyanacrylat Primer im Netz suchen. Leider sind die Primer nicht ganz billig. Braucht man große Mengen, am besten selber machen. Über eine Patentrecherche wird man fündig. Einige Patente dafür sind abgelaufen.

Sie haben recht, die Batterien halten rechnerisch ca. 200 Jahre, wenn man die unvermeidbare Selbstendladung nicht einrechnet. Dennoch können die Batterien schnell leergesaugt werden und zwar dann, wenn unbeabsichtigt Tasten gedrückt sind. Dass passiert leicht, wenn das Teil in einer Schublade liegt und andere Gegenstände auf die Tasten drücken. Insofern hilft die Modifikation schon. Leider wurde mir der Sachverhalt erst nach dem Video bekannt. Sonst hätte ich darauf hingewiesen.

Dann hattest du Glück beim Nachkaufen der Batterien. Ich habe Varta Batterien nachgekauft und weniger Glück, denn sie hielten nur 4 bis 6 Monate, wohingegen die originalen ein paar Jahre hielten. Ich habe das Problem mit allen CR 2025 Batterien in sämtlichen Geräten. Die neuen halten nur ein Bruchteil der Zeit der alten…

2-3 Monate, dann Batterien leer. Egal ob Energizer oder linglang.

Good to see your like it.

That is true, there are surely cheaper solutions. I think the advantage for my own solution is the possibility to calibrate it very accurately. After calibration I found for 3KG an inaccuracy of about 0.2 g OK, for food recipes it is not that important, but the project can be used for any other purpose and weight, since the weight unit in use does not matter. And the quality is just dependeing on the repeating accuracy, because it can be calibrated. So I think the good thing is not the design of the scale, but the software I wrote for the arduino.

Right, that will work also i learned. I came to glass sand because there was a time when I collected porcellain and often I got broken pieces caused by the transport. So I looked for something that allows to fill small holes and missing chips and which is partially transparent. So for porcellain it worked quite well. And then I had the problem that my lawn mowers zimcum tank broke off in the middle of the job, so I glued it using super glue and to make it a bit more stable I used the glass sand I knew form the porcellain repair to stiffen the structure. And believe it or not, since I fixed the tank with super glue and glass sand it didnt break again. Considering the vibration that led to the rip of the tank, this is surpising. So I thought it could be helpful to share the experience. Later other users informed me, that bicarbonate does the same. I cannot really tell which is stronger, but for me glass grain works well.

Yes that was pleasure, because all of the images are done within a few minutes and they develop in a certain way themself just by using some blender functions. I am often surprised myself about the results.

Thanks a lot - I hope you still enjoy my channel.

Thanks - Perhaps you have seen the new software i published.

Hello, this is a problem, since I do not own a business, I cannot sell parts. However you may use a 3D print service to order the parts. But still you need to post process the parts as described here: ruclips.net/video/U1c4R2EB83A/видео.html If you need support, let me know, so I can answer questions if you have some.

Thanks !

It makes me happy if you like them. Indeed I really use these images as a screen saver slide show on my PC. If people are interested I have no problem to provide downloads for such purposes. I was impressed myself how easy it is to create 3d objects using Blender, so I made some.

Die Leitungen sind einzelne Litzen aus einem sehr dünnen Steuerkabel.

Hat man so was nicht herumliegen kann man auch Dekoderlitze kaufen (0.05 mm2)

@@Bechelede Dankeschön, wie effizient ist der Umbau jetzt genau? Lohnt es sich denn die Litzen zu verlöten, oder bringt der Umbau nur sehr wenig?

@@RiptoRage Hallo, der Umbau bringt nur bedingt etwas. Nachträglich stellte sich heraus, dass der Stronverbrauch des Kobil nur dann extrem stark ansteigt, wenn irgendeine Taste permanent gedrückt ist. Beispielsweise wenn etwas auf dem Kobil liegt. Ist keine Taste gedrückt, hält die Batterie fast endlos lange. (Rechnerisch mehr als 100 Jahre)

If I would use some nice music I would perhaps have some trouble with licensing. So I had to choose something free. The idea I used this, is to show the possibilities of the eye mechanics in conjunction with the software: bechele.de/?page_id=55 www.thingiverse.com/thing:2781756 And I hope thats what it does. The video is intended for people who consider to use the software or the eye mechanics for their own project.

OK, the reason I used "Old Mac Donalds" is to show the possibilities of the eye mechanics. Its free to use it and does its job. It's surely not my favourite music....;-)

i liked the song ❤️

smile ...

Ist das nach den Umbau passiert oder hat es damit nichts zu tun ? Sowas hatte ich bisher nicht.

Das ist mir auch passiert, nach Anschluß an USB. Jemand im Internet meinte, an so Sicherheitsgeräten manipuliert man nicht, sondern schickt man an den Hersteller zur Reparatur. Allerdings war mein Generator schon älter, dass keine Garnatie mehr vorlag. Ich habe den damals auch gratis von der Sparkasse bekommen.

Yes, you can find it on thingiverse for example: www.thingiverse.com/thing:4934332
