Good to know Mike put it on his website... Thanks for spotting it! -
Motor driver inside hubs is current limited to a fairly low value (400mA continuous). So using 0.7/0.8 A per port is really safe. 1.5A for a pup hub, 3A for a C+ one.
-
Took me a while to find... go to the white tab, first is an "expander" block to add under motor selection.
-
The wait is over, thanks ;)

Using Relays With Lego PF
Philo replied to MaxBrix's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Chance is pretty low: motor driver inside receiver does include flyback diodes (see datasheet). After all, LEGO motors are also inductive devices! -
??? https://www.bricklink.com/v2/catalog/catalogitem.page?P=3065#T=S&C=17&O={"color":17,"iconly":0} (Granted, that's the version without bottom tube).
-
Does anyone know if it is possible (and how!) to access the rotation encoder of Control+ motors? I'm trying to create a movement sequence for the Liebherr... Thanks in advance!

General Part Discussion
Philo replied to Polo-Freak's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Not that well, and it grinds quite a bit. But it's a fun finding ;) -
Simply copy again the folders of the archive in the same place as you did first. Connectivity is stored in another folder so no risk of losing it.
-
Yeah, already had this issue, part designer completely botches the parts. After adding connectivity, overwrite the parts with the untouched LDraw parts from the archive.
-
Dunno what's wrong with my file, when I open it as a zip I see the custom folder with parts inside, like in yours. Anyway... other method that I know to work fine, here is the custom parts folder containing the 42100 parts (and a few recent other ones you could find useful...). https://drive.google.com/open?id=1BY2kstW74rRNR5g5gWL1syaIEgePtIMl Add the contents to your CustomParts folder (located in C:\Users\<your user name>\AppData\Local\Stud.io) I haven't tried to add connectivity on these parts, but you seem to know how to do that
-
Did that (https://drive.google.com/open?id=1n7vUdkB4xFNDfEslgqdk-qAfXiQjP--b) but when I try to open it after removing my custom parts folder it doesn't load. Did you do something special for your LA file (which opens fine)?
-
You know that the "real thing" is available on PT with all gory details, don't you? https://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/46891.dat (actually all 42100 parts are available).
-
Interesting cable generation method... I would suggest to make your segments a tad longer than needed to avoid the gaps (Studio renderer shrinks a bit everything to create fake seams between bricks)
-
I wouldn't expect weird behaviour. IR receiver "idle" power consumption should be very low anyway (about 17mA, see http://philohome.com/pfrec/pfrec.htm ). Motors themselves are much more tolerant and have no intrinsic voltage limitation. The main problem is overall power dissipation for a heavily loaded motor (dissipated power raises as the square of voltage...). My motor tests are done up to 12V (http://philohome.com/motors/motorcomp.htm).
-
Theoretical value is pretty low: the motor driver inside the IR receiver (LB1836M) has a 9V rating, with a 10.5V AMR (absolute maximum rating). So if you want to be on the safe side, you should never ever exceed that 10.5V limit.
-
This happens with that kind of switching power supply. Aluminium capacitors used often have a poor life time, shortening even more as temperature raises (divided by two for a 10° temperature increase!). Their electric losses raise, and finally they explode...

42100 - Liebherr R 9800 (Technic 2019) Download MPD (OMR compliant) Known errors: No stickers. Done with LDCad 1.6c Rendered with Studio 2.0
-
Here it is... https://drive.google.com/open?id=1AFjca46Tns4JiXwK2WUcATmUuVGWvVp- To use it, unzip it and place its contents in your C:\Users\{your username}\AppData\Local\Stud.io . BuWizz and PF connector parts will then be available in Custom Parts palette of Studio.

@Tommy StyrvokyI hope you don't mind me highjacking your thread (and somewhat stepping on your toes ) ...and Sbrick already exists in LDraw, so I made a little parts pack with S-brick, S-brick+ and PF connectors, it is available here: https://drive.google.com/open?id=1zqznTvpj8voAT7_kCGyAlut-QjTVkCk2 To use it, unzip it and place its contents in your C:\Users\{your username}\AppData\Local\Stud.io . Sbrick and PF connector parts will then be available in Custom Parts palette of Studio. More details on custom parts in Studio forum: http://forum.bricklink.com/viewtopic.php?f=4&t=965&p=2615&hilit=customparts&sid=a0487a9d7213c77248f4ce56001e5072#p2615 The parts pack method is a bit less intuitive than distributing .part files, but it avoids the materials issue mentionned by @Tommy Styrvoky. Some rendered results:
-
A note to people wanting to document their 42100 modifications: all the specific new parts are now available in LDraw format (linear clutch, long LA and bucket ). Of course Control+ motors and hub are available too.
-
AI can do wonder from a simple photo... I often use Plantnet app to identify plants I see during my walks, and I am always amazed by its performance! Now I guess this is less useful for an expert!
-
Yes, but that's not an option for a 42099 B-model

Whoops, thanks for the heads up! A cut&paste error, this value applies to motor PWM signals, but VCC on the Pup connector is indeed 3.3V. Corrected! http://www.philohome.com/wedo2reverse/connect.htm
