    I first thought this to be a problem too. But after a little thought, that gives us kind of a load-locking differential as some people hoped it would be

    Welp, that didn't help. Even with extensive firmware updates, Brickcontroller2 doesn't work on my GT-i9195i with Lineage OS 16. Now i don't know what to do of this excercise. AVCampos' and my experiences didn't show any data deciding whether a smartphone does or doesn't work with Brickcontroller2. I guess i'll search for a cheap used LG G2 on ebay now...

    We found the culprit: i can't. According to nRF this is not supported on my device. This list of "Device Support For Beacon Transmission" kind of confirms it (only for GT-i9195, mine is a GT-i9195i) Unfortunately i couldn't find any information whether newer versions of lineage are able to fix this. Although it may be, as @AVCampos's LG G2 (i guess LG-D802) shouldn't support it either, according to the list. I'll try to install lineage OS 16 and see if that changes anything. Skimming through the xda forums, i've got a little bit of hope

    Thanks for the input. That's very intresting as the G2 only has Bluetooth 4.0 as well. Have you been able to connect to a C+ hub in another version of BC2 ? @imurvai, are you sure the S4 Mini is a lost cause, even though nRF Connect was able to connect to the hub?

    I'm going to search for used phones tomorrow. (I couldn't find anything about a Galaxy A4 series) As this will be used exclusively for Lego i'm not willing to spend more than 50€. (Especially as my daily used phone cost only 100€)

    A friend just gave me the idea to use a BT dongle on the phone. I'll try that when i'm back home. By the way, is the version 2.3 on apkure the most current apk?

    Buwizz seems to have the same problems. I tried the Buwizz2 app version 1.0.3 (i couldn't find an apk vor v1.0.4) and it too didn't find the hub or anything else. The official Control+ App doesn't get further than the Start-Up Screen. I could test the hub with the Galaxy S7 of a colleague and it works. So the problem lies definetly in my phone. Is there any way to debug apps on android via some form of command line or something? The four IR receivers brickcontroller always seems to find are most curious. Maybe this helps to locate the problem in the code? Maybe my Hardware just isn't up for the task, the S4 Mini only supports Bluetooth 4.0 but i couldn't find any data on the Control+ Requirements. Powered Up needs 4.0 and higher. [Edit:] I just found out that the official app needs bluetooth 4.1 or higher It would be incredible frustrating if this was the problem as the difference between bluetooth 4.0 and 4.1 is only a software update. It's just that no company provides the necessary update to their old hardware @imurvai, do you by chance know the cheapest phone that can run Brickcontroller2? It seems i have to buy a new phone just to play with my lego.

    It does:

    Yes, i gave it every permission possible.

    Before building 42100 i wanted to try the brickcontroller app. While i succeded in connecing a XBox One Controller, the app can't seem to find the control+ hub. "Scanning" just returns four times "PF Infra" recievers, no matter how i try (the c+ hub should blink like a strobe, right?) I tried Version 2.3 and 2.0, rebooting also doesn't change anything. I'm on Android 7.1.1 with LineageOS 14.1 on a Samsung Galaxy S4 Mini with no Google Apps. I'm pretty sure i'm doing something wrong, could you please enlighten me?

    Seems like a great project, i'm curious what speeds you will achive. Although I understand the space constrains, i suggest to support all gears on both sides and to turn the motors 90° so you only have one bevel gear connection. Supporting the gears on both sides greatly reduces the bending forces in the axle (and possible gear misalignment) and removing a bevel gear reduces friction as they introduce axial bearing forces.
  12. schraubedrin
    That's a really good write-up, thank you very much! On a side note: i personally don't like to use 8-tooth gears in drivetrains as they seem to add friction. (unfortunately i couldn't use my testing stand to test this)
  13. schraubedrin
    That's just sad. Your reviews have been a part of the reason i became a forum member (and i've always been part of the "stay up till midnight"-crowd) There are very little reviews that convey the feeling of building and understanding a model as good as yours. As you're describing and picturing the model during the building one gets to know the model well enough to be able to discuss it with members already owning it. (The only increase in detail being @grum64's projects) As the next best thing, i would enjoy those too :-) I really hope you can sort this out with LEGO. With the designer interviews by @Sariel, there seem to be more communication channels open than before, maybe they'll hear it this way...
  14. schraubedrin
    That's an ingenious solution! It took me embarrassingly ling to spot the 7L gear rack.
  15. schraubedrin
    Can you show a detailed picture of the steering mechanism? Based on the current pictures i'm unable to reconstruct it.
  16. schraubedrin
    That's a really nice and clean build. I like that you didn't use too many parts. How's the steering angle? I always have trouble building a good mechanic with the small steering arm.
  17. schraubedrin
    I should have guessed that you already optimised this drivetrain to death Another idea to reduce the torque on the shifter rings would be to double them. But this would be a huge step-up in complexity with questionable outcome. Whatever you do, i'll follow this thread closely
  18. schraubedrin
    This will hurt the efficiency a bit, but have you tried running the complete gearbox at higher speeds to reduce the torque?
  19. schraubedrin
    Since the motors are strong enough for the 4th gear, why not raise all gear ratios? So the gears go from 1.00 to 3.00? In the end i guess you'll mostly use the first and last gear, so the gear jumps in between only help smoothen the transition.

    Wow, it's awesome what people are doing with this set. Thanks for showing me! Unfortunately my dark age began just before this set was released, that's why it took so long for me to acquire it A good idea, as the necessary parts are pretty generic so quite a lot of people will be able to participate. Except for the steering rack, it needs another solution using current parts It's my pleasure I'd be interested what you think of it. I'm happy about your feedback, it seems to be not a bad idea to take another look on older sets.

    After finally getting the 8081 Extreme Cruiser and enjoying the build, i just had to make it remote controlled. There's so much space in this chassis! And small offroaders are always a win (Unfortunately i neither have a good camera nor a nice photo-studio, so the pictures aren't that nice.) Everything fits nearly seamless, except for my horrendous cable management: (original on the left, MOD on the right) For propulsion i used two L-Motors geared 25:28 to the wheels, steering is done by a servo. As i built this mod from my own parts, i didn't use the original Technic Gear Rack 1 x 2 with Ball Joints. The result is a convoluted mess with far to much slack. But it works well enough to drive over other peoples feet Here's the belly shot: The servo is located above the L-Motors. To insert my steering solution, i had to ditch the original fake V4. The Battery Box fits perfectly in the boot. And replacing it doesn't take more than opening the boot lid. to take it out. (It's positioned on short axles) And finally i remodelled the front a bit, closing some gaps and installing glowing lights In the end i'm really glad, that i searched for this model even though it's relatively old. It's a nice build, a good parts pack, very modable and still nice to look at. @moderators: i started this thread because no such topic existed and i didn't knew in which of the other 8081 topics i should put my post. Feel free to move/merge it.

    Incredible, that you made this a working detail. Now i'm really looking forward to the video "WIP LEGO Technic replica of the Liebherr LTM11200 crane, part 3/3" to see the boom in action. Because with the pictures i can't figure out how this will work, everything seems connected...
  23. schraubedrin
    I'm in awe of the size and complexity of this model. There are so many ingenious details! Until now i didn't understand every part of it, are the ends of the blue 3L pins at the tip of the boom for an extension? And what are the linear actuators on the boom for?
  24. schraubedrin
    Because i have a hard time seeing those perfect fits, i recently build tools to help me find them: It's a collection of Pythagorean triples and multiples of those with axles in the corners to point at/insert in stud holes. They make building stiff constructions a lot easier and faster.

    The new Ninjago Set 70670 introduces gears that look to me like the old style gears: (timestamped video)
