Technic 2018 Set Discussion
suffocation replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Guys, please help out a partly colour-blind bloke with a lousy monitor. Are the cab panels DBG or LBG? And is that 42008 green I see on the crane arms? -
Someone may have posted this already but it's worth pointing out: you can actually use the Buwizz unit as a battery box, couple it with at least four IR receivers (can someone with more see how far they can push it?) - i.e. 8 independent channels - and have all the motors running at slow, normal or fast speed. All you need to do is run the app, set it up to run at the desired speed, give any one slider an input and it's done. I'm not sure how healthy the fast setting is for the IR receivers; in any case, it's a cheap albeit less effective alternative to the SBrick-Buwizz combo. Edit: obviously, if you're content with the slow setting then you needn't run the app.

Tried with an array of Android devices - no luck. What DID improve things - more or less - was switching on the location device along with the BT, which for some reason greatly improved responsiveness. Now I'm facing another issue, though. When I have three or more active sliders, I can only use two at the same time. This is pretty frustrating because if I'm driving a tracked vehicle with a subtractor I want to be able to run the two tracks independently (2 separate XLs in my case) as well as the subtractor's motor (1 M), all at the same time. I wonder if this is a deliberate software limitation to limit battery drainage or something like that, and if that's the case if it can be overcome using SBrick.

Let's try once more before I see myself forced to return what seem to be two dud units. I'm using a Samsung J3. No way to update the firmware, and the lag between the controls and the motors is unnerving. I've tried all the tricks given in the thread but none of them seems to work. Has anyone else had a similar experience, maybe using the same smartphone?
-
Same here. Migros had it going for 181 Swiss Francs (156 Euro) this week but I just don't think it's worth it - lousy design, lousy assortment of parts.
-
What an awesome model! And Blakbird's renders are top-notch. Thanks to both of you for sharing.
-
Would be nice to see a full video and a few belly shots, which always seem to be missing.

There's always pendular suspension if you want. It's the least sophisticated but it beats solid axles and probably takes up the least space of all. Or, if you're willing to go a more complex but highly rewarding route, you could replicate Pipasseyoyo's brilliant springless multilink suspension. There's an LDD file out there somewhere; if you can't find it I can send it to you as soon as I find it on my hard drive.

I like it a lot - it's got a nice aggressive look. A real-life version of something like this would look terrific in a post-apocalyptic film. You're improving in leaps and bounds!

Love it, especially how all the studded parts make it look so imposing. Do you have a link to the string you used?
-
Thanks @Anto I bit the bullet and ordered a couple yesterday. Got a mail today telling me they're already on their way

42055 already had all the parts you needed to get two functions through a turntable. One thing that might not be clear from the pictures is that the driving ring ( ) going through the turntable must be without the driving ring connector ( ). This way the driving ring and clutch gears spin freely around the axle, giving you two independent coaxial functions. Of course, you can replace the driving ring and clutch gears with a 4L differential - the end result is more or less the same.
-
Can anyone confirm that the prices listed on the BuWizz website are without VAT? I was kind of shocked to see the quote for 2 units shoot up from $220 to $268 (plus $20 shipping).
-
Exactly - one input, seven outputs. You can arrange it to have more or fewer outputs, of course. You could also have the input in the middle and three (two, four, whatever) functions mounted vertically on either side, like this (sorry about the hideous pics):
-
This is a very basic setup (you'll need much stronger framework, of course) that gives you seven independent, two-way outputs. Don't cringe at the three 8z gears - they can carry more than enough torque for an excavator.
-
Indeed @Mechbuilds - Once you've cracked the coaxial conundrum, I recommend having a look at the substructure of 42042. It's much lighter than 42055's but still very robust thanks to the use of diagonally placed beams.
-
This ^^^ You'll want a sturdier undercarraige than 8043's, though. As for the gearbox, how many functions would you like to implement and using how many motors?
-
It does turn 360°. Both the red and the green function pass through the turntable coaxially.
-
You need a configuration that looks something like this (I think it's one of Sariel's builds):
-
Really looking forward to the instructions for this. Using Buwizz would take some weight off while providing more power, so you could probably get the model to drive without having to ditch the whole gearbox.
-
I used the low-speed value from Sariel's gear ratio calculator, which gives me 2.48 N/cm. But yeah, it's just inconclusive theory
-
I think the average price of diffs (second-gen ones, at least) is lower on Bricks and Pieces now than it is on Bricklink. In any case, the former ensures you're getting new, original parts. I'd get a handful of second- and third-generation diffs - they have plenty of uses that transcend traditional vehicle drivetrains.
-
The friction induced by planetary gears does indeed eat up a ton of torque. Your theoretical output is around 500 N/cm, which is roughly the equivalent of 34 XLs; of course, practice is quite a different kettle of fish. It'd be nice to measure the effective output at one of the axles to see how much torque is lost along the drivetrain.
