I also gave our app developer an idea about about adding a speed gauge which would calculate the speed of the model with the help of the wheel diameter and gear ratio. The statistics and the speed gauge sounds great! 26 minutes ago, Zerobricks said: Inverse kinematics is a bit too much, especially since BuWizz is used more for MOCs than official models which have all the lever lengths predefined. I did not mean inverse kinematics, such as controlling the end point of an arm with 3 joints, I understand that that's complicated and not your target application here. I was only referring to controlling a single large LA within its full range, and the possibility of calibrating its range (to be able to stop at the ends without running on the built-in clutch). Would that be possible? For that no predefined lever lengths are needed, just to be able to search for the end positions by detecting that the motor has stalled. Quote

It's basically same as return to center steering but using a normal non-return slider. Should be easily possible. But remember the first release of the app won't probably include all the possibiilites, we are concentrating on simple motor control, return to center and feedback statistics first because these are the most needed and basic functions.

Should be easily possible. Sure, they are quite similar, the main difference I see (at least in case of the technic hub's FW) is that steering can use the absolute zero position of the motor (baked into the HW, small max angle), while moving the LAs uses relative positioning, which can be preset and has a large max angle range. Just wanted to know if both will be supported at some point in time. And starting with the most demanded features is totally fine and understandable. The applications that I have in mind would also target construction machines with LAs, so wanted to clarify if it will be supported at some point in the future. Also, more important for me will be the FW support for control commands, once the protocol is published, I could program all sorts of exotic control interfaces on top of it in my own app. Quote
allanp Posted February 7, 2021 Posted February 7, 2021 The ability to measure speed by inputting the gear ratio and wheel diameter sounds really cool! As you are already planning to measure things like current, voltage, rpm and so on, is there a possibility to display total power in watts or something? Quote

Maybe the community here can make a list of wanted functions and priorities we can use to help guide the app development. Quote
HectorMB Posted February 7, 2021 Posted February 7, 2021 Other question that comes now to my mind is how BW 3.0 compares, in terms of performance, with the PU box (like the one in 42100 and so on)? Is clear that BW 2.0 stepped up from the performance delivered by PF batteries, but I have no idea of how it does when compared to PU... Quote

The difference in speed and climbing ability is very obvious, I will post a video here once it's published. Quote

Also, PU seems like it has had little performance upgrade over PF, and the protections in the hub may even make it worse, so if we assume that Buwizz V3 improves on V2, while PU is similar to PF, the difference in performance should only increase!

pdw Posted February 9, 2021 Posted February 9, 2021 How does the on/off button work on the BW 3.0? On the website photos it looks like it's recessed into a stud. Quote

sephiroth117 Posted February 12, 2021 Posted February 12, 2021 Thanks for the mail heads up regarding B3.0, happy to see it’s on schedule and working well ! - regarding the battery are they custom made or it’s something standard we can easily find online ? - Also, any chance we’ll see the bluetooth specifications so that we can interface Buwizz 3.0 with any app when the product releases end of this month :) ? The app is great of course but for STEM/programming it would be cool to have those specs Quote

mudseason Posted February 24, 2021 Posted February 24, 2021 I was going to preorder the beast to power my modded 42099: geared up 2 times, but with 4 motors instead of 2 + an old servo for steering >> perfect match for the buwizz 3.0 I would also have a spare connection for the lights... ,.. then I crashed on the price, 181eur on pre-sale (sorry, but I have to include vat). does any pre-sale coupon for pre-pre-sale exist that I have missed? Returning customer loyalty something? That is going to be my 5th Buwizz ... Quote

mudseason Posted February 25, 2021 Posted February 25, 2021 yes, I'm sorry that my comment sounded a bit lame. I know very well that buwizz 2.0 is a great product and I expect buwizz 3.0 being even better. Obviously you did your evaluations to set the tag price, price that shall not only encompass the HW part, but also the SW one. I just had a "small" letdown moment after the excitement. So to switch to a more technical question: do you confirm that 1 unit can drive: 4 PU large motors + 1 PF servo ? thanks. Quote

BuWizz 3.0 can drive/read 4 PU/Boost/Spike, etc... devices and has 2PF ports to drive PF motors/Leds, etc... All the detailed info is in the tech specs: https://buwizz.com/tech-specs/ Quote
sirslayer Posted February 28, 2021 Posted February 28, 2021 (edited) Wow, check out this YouTube video of the new BuWizz 3.0 pro !!!! Edited February 28, 2021 by sirslayer Quote
Jurss Posted February 28, 2021 Posted February 28, 2021 Demand for different gears, u-joints etc. will grow frow now on. Quote

howitzer Posted February 28, 2021 Posted February 28, 2021 Looks great, but I wonder about the price. All those nifty features won't come for free so I'm guessing it's going to be a pretty expensive. I could see myself paying like 50-100€ for this but probably not something like 200€... Quote
sirslayer Posted February 28, 2021 Posted February 28, 2021 $149.00 USD in America for the BuWizz 2.0.. So I would estimate $200-249 USD range for the BuWizz 3.0 !! Quote

Not exactly cheap, but it seems to represent decent value compared to V2, because fewer models will need two buwizz to run at full power. Quote
