Oh man ... no, I haven't. But now - thinking of it ... it would mean that the 89 can go forward in an indefinite loop - made from straight track only ... Best, Thorsten

But this could do the trick - as I believe the issue is not the City hub's firmware but the communication between hub and app, as other controlling BLE software using the LWP3.0 commands (e.g., Legoino, VB6 with BLE stack) work flawlessly. Best, Thorsten

Very nice run down, a lot of information, good judgment, this is a true educational thread. I will closely follow what you publish here! Thanks a million for doing all this work. This is true, valuable EB superior content. All the best, Thorsten

Very well said. I completely agree. Me too - I am out of my dark ages a little longer but EB helped me a lot, helps me a lot and is my "single point internet interaction interface" for interacting with all you brilliant and fantastic folks! For me there is YouTube as video storage facility and there is Brickshelf for pictures and other stuff like LDraw files. I know that Brickshelf is from yesterday, but so am I. And it has served me very well from the day I joined - some 10++ years ago. Oh yes, why not, it will be fun. All the best, Thorsten Oh yes, and this one. For sure!!!

Holy crap, I forgot!!! @zephyr1934 - Benn, I completely forgot (and this is terrible), that the making of the coupling rods of the 89 is >heavily< borrowing from your design; this is what I used as reference, i.e., your Brickshelf repository: https://brickshelf.com/cgi-bin/gallery.cgi?f=510263 Let me explain: I happen to have a mechanical engineer in my research group, who is currently doing his PhD thesis in mechanical engineering, however, for designing/making things for our group, in projects that are dealing with advancing metrology for crazy things like wafer scanners; @JopieK certainly knows which company in Veldhoven is meant here. He is jointly paid by me and my colleague in mechanical engineering. My group has a Tractus3D printer at hand, and my colleague has a bunch of others; one can actually handle 1x1x1 m3 large "things". So he looked at your Brickshelf and told me that he needs some more data. I told him that that is also available somewhere else (the technic hole dimensions etc.) and he used that. To be absolutely clear: The shape of this rod is close to what you designed and offer in your shop. I sincerely hope this is OK. The connecting rod is his design - I told him, it would be nice, to have a small diameter "round" rod. The reason was that a first attempt using the flat design was absolutely OK, but did "hide" a bit the coupling rod, as it is attached to the rear wheel set. The original BR89 has flat rods, but rather "tiny" ones. Again: I hope this is OK. If not, please let me know. All the best, Thorsten

Says the one, who can make an 8-wide Intercity train running on a DBG R40 9V circle in pentagon geometry Here is to insanity! All the best and keep up the insane thinking, trying and making! Thorsten

Update (I did this now on three different posts - hopefully I don't get mod-flak ... for that) Video is available here:

I'd say two more? They maybe fit in - making a train pentagon. Best, Thorsten

I do 100% agree! Also, Google has apparently very nicely indexed the entire EB content. Searching on EB for EB content is really tough (at least for me) - but searching for EB content using Google is working very well. Best, Thorsten

So finally I made a video - and as I said: I suck at making videos: Bad lighting, bad focus, bad whatnot. At least I updated my license for the VSDC editor Whatever, here it is, make sure you focus on the turntable and other LEGO stuff visible and simply ignore the 89 (@JopieK let me know if I need to move this to the Community forum) Best regards, Thorsten

@Hod Carrier: I have just published a video on YouTube showing two City hubs with attached PUp L-motors (one in the turntable, one in the BR89). Both motors are operated using the speed commands of Legoino. https://www.youtube.com/watch?v=0iUaD10OPnk (Link only, as there is evil content in this video) Example code for the turntable, when using the PUp remote (manual control): TTH.setAccelerationProfile(portA, 10000); TTH.setDecelerationProfile(portA, 10000); TTH.setTachoMotorSpeed(portA, updatedTTHSpeed, maxTTHPower); TTH = turntable hub; 10000 = time to reach target speed, as per LWP3.0 protocol; updatedTTHSpeed = 0 ...100% speed; maxTTHPower = 0 ... 100% power to be used by the hub to maintain target speed setting. I am using 40% power max. as the L motor easily rips the turntable drive apart when blocked, but 100% power max. on the BR89. You can put these commands into a loop with a 100 micro second delay (to complete each BLE transmission) - no problems found, just tested. Best, Thorsten

The City hub is as is: Current LEGO firmware installed. As @Lok24 said: It may be the PUp app or the communication between app and hub. However, I doubt that the cause is the (original) hub's firmware, as the (original) firmware works flawlessly with Legoino. Legoino is calling up all the stuff that was documented years ago in the LWP3.0 protocol files on GitHub. With Pybricks I believe more is going on regarding hub firmware changes, others will know much better (I have not used Pybricks, as Legoino with the original hub firmware does all I want). So yes, all PUp components are untouched And sure: TLG could very well address these issues- to be honest, I believe they have to, as they offer a product that does not work correctly. Best, Thorsten

True. Well, I am using PUp all over the place - with ESP32s/C++(ArduinoIDE)/Legoino. So far I didn't have any issue. The good thing is, that Cornelius is still actively working on Legoino on Github - each time some weirdos bring up issues (rarely the case!), he fixes it - usually during his vacation time or on holidays ... also his library is written in superb C++ code. Best, Thorsten For exactly what?

And I do appreciate that very much! I believe we should know how TLG is handling their very own software applications: Worse than apprentices. And how their always praised customer support is informed, when it comes to non-100%-plastic pieces. It tells a lot about their status of electronic hardware and software development. BTW: The City hub is not the source of the erroneous behavior: With an ESP32 and Cornelius' Legoino installed, controlling speed, i.e. using the tacho of all PUp motors, everything runs flawlessly. You can set the #degress of rotation, you can use speed settings as often and fast as you want: Works. I have retrofitted a 10-wide BR89 with a PUp L-motor and the City hub, and it is beautiful to watch her going through curves and straights without notably changing speed. The same holds true for this turntable., operated by a City hub and PUp L-motor. It is the PoweredUp app, not the City hub's firmware. Best, Thorsten

So - I don't. I do reply in this thread to those who are not looking at numbers. At exposure. At "worth". I do reply to those who still wish you well @JopieK, @Feuer Zug, @XG BC and those who still value the reply of just one member - or the feeling that someone may actually read my post. That's all there is. You know, when I lecture really tough stuff in a masters class - let's call it "Molecular reaction dynamics" - there are sometimes less than 5 students enrolled. Because they don't have to suffer through that one - they can elect other classes as well; and apparently these are less ... time-consuming. But you know, I have SOE, and I could let people know, that due to lacking enrollment, I cancel this class. No one would complain. I am saying this: As long as one student is enrolled, I'll teach this class. And I can even do that in my office. So, to all the folks making EB great: Here is to you I have a different take in my life - even when an entire planet is going downhill: " Wenn ich wüsste, dass morgen die Welt unterginge, würde ich heute noch ein Apfelbäumchen pflanzen". Yes sure, dreamer. What is wrong with dreaming? Should this site go down, it goes down, as many things go down. But leaving? No. Not for me. So ... time to finish my video on a turntable turning a BR89 - I suck at doing videos. Even knowing that no one will watch it All the best - and folks - rock on. Thorsten

Made my day as well - and these are 9V R40's! Not the plastic stuff Best, Thorsten

I totally agree. Unfortunately, I had the dinosaur exposed to Southern California sunlight for more than two years (it looked so cool though, even without any "programming" action) - and that turned the tiny flex system cables into non-flex system brittle pieces of stiff ABS. Photochemistry at work. Yes. The dinosaur. So cool. Best, Thorsten

I have one (from BL) - and I can confirm that you can tell this motor to move xyz degress and it does. Best, Thorsten

I guess so ... and nicely supported by the brilliant naming of all the PUp devices, TLG came up with! Best, Thorsten

And that is the most powerful and reliable way to do it - nice. I really appreciate this way more solid information as compared to what is out there. (Well, as far as I searched!) But again (sorry for being slow): I believe PUp M is relative only, PUp L and XL is on you/us. Is that correct? Best, Thorsten

Hee hee - you know, I was born in "very" Northern Germany - never felt the difference between Slesvig and Schleswig - 45 years of enjoying vacation on the most beautiful island in the world - Fanø - yes, I feel up to the challenge. Thanks a lot! All the best, Thorsten

Absolutely, really. What I find challenging though is to live up to what the original designer did. When you throw in a PUp L motor and the City hub, the going gets tough, 10 wide or not. When you design bottom up - with these feature in mind up front - it >may< be easier. To be honest, I had a terrible time modding @Ben Beneke's BR23, but only before he told me it was more than OK. He encouraged me to do so. With the BR89, I have trouble reaching out to "Alex", the BB designer, to ask for permission on messing with his design. I sure hope, this is OK with him. All the best, Thorsten

Well - that is the problem: Upon modding her, I used > 50% of LEGO pieces. However, that caused a heavy left over of BB pieces. I then fired up MLCad - "recorded" everything - and then reverted as much as I could to the BB parts I had. After all - it is their very set. I'd say I am now on a 80/20 BB/TLG ratio, and that renders moving this post to TT - far less favorable. Thank you very much! I do think so as well, as you can do every single change brick/plate wise in LEGO world - and actually there is more you can do with LEGO stuff as you can do (currently) in BB world. But it is, what it is - and it is no problem at all. Oh yes - oh yes. But then, you'll need to fan out at least three - four times what BB asks for - the "stand" alone is accounting for about 1/3 of the piece count not even explicitly shown here . This is just so nice to watch: You know, when I drilled my first hole into a LEGO plate, I thought: This will be the end of the universe. Well, it was not. For my Croc I literally drilled through a couple of plates - and now I can fire-up the City hub inside by pressing a tile on the roof . Skillfully (!) cutting down a flange like that, when you don't have the blinds - just perfect!!! All that surplus ABS flying around - my world. Thank you all for the very nice replies - here in the Community Forum. BTW - as this is also the forum hosting the "What are you listening to " thread: I am listening to: "Wer wartet mit Besonnenheit Der wird belohnt zur rechten Zeit Nun, das Warten hat ein Ende Leiht euer Ohr einer Legende." Well, and then all hell breaks loose ... Thanks again for finding me here. All the best, Thorsten

I believe linear medium PUp motors do have such a rotation sensor inside with 1° degree resolution. They don't have an absolute position encoder, which means that when you power on the electronics within the motor (i.e., plug them into a hub and turn the hub on), it does not know where absolute zero is, it just counts degrees up/down from its current position. Linear L PUp motors, according to Philo's motor page know both the relative (as per relative to the position they have when powering them), as well as absolute position, however they have no position zero mark on the case/shaft, which is weird but ... so you have to find out, where that zero position is. Hmm. I don't know - when it is like that, then you should be able to get the abs. zero info from the hub. Never tried that thought ... Best, Thorsten

For me, it is not only another level - this was built in another universe. Completely unbelievable. The video is also excellent ... Wow.
