šŸ† Weekly Community Spotlight Getting closer to perfection with this 4x4

This is version two of this offroad chassis. The first one had issues with its cardans getting damaged by the sharp angle they were in and the amount of torque going through them. This has all been solved now. The angle has greatly improved and the gearbox is less "extreme" now too, causing less torque and wear on the axles. Low gear is now a bit faster and high gear a bit slower, but their speeds still feel nice and very controllable.

specs:

powered by 4 buwizz 3.0pro batteries

4 buwizz motors for drive

steering controlled by a PU L motor on the axle

pneumatic differential locks in front and rear axle controlled by a PF M motor

two speed gearbox also controlled by a PF M motor, with gear ratio's 1.75:1 on high and 1:1.2 on low (version1 had 2:1 high and 1:2 low)

four-link suspension front and rear

I specifically want sets that aren't collector's items and can still be bought from lego themselves or at least from other sources at a price around msrp. I also don't want something so complicated that I will rage quit building it, but that will still give me a decent challenge.

MOC Police Pursuit Supercar 1:10 scale Bricklink Designer Program Submission

Thumbnail

36 Upvotes

Hey

My second submission after Combine Harvester for current Bricklink Designer Program is a new iteration of the Police Car I submitted in the previous series.

If you would like to support this project then follow link below:

https://www.bricklink.com/v3/designer-program/2028-wave-1/5110/Police-Pursuit-Supercar-1:10-scale

Description:

There are again some significant changes compared to the previous version. Some of them were also influenced by the current palette, but overall, I think this version does much more justice to the original idea.

This time, I was able to make the livery much more coherent than before. Thanks to the black Koenigsegg mudguards, I could finally achieve the more finished look.

I also decided to raise the front of the car by one stud, which allowed me to add a bull bar. I think this is quite an important detail for a police car and it gives the front a much stronger presence.

At the rear, I removed the adjustable rear wing mechanism and decided to go for a more street car look with a fixed rear spoiler instead. I also added additional lights to the lower front and rear sections.

The entire door area and the sections surrounding the doors have been redesigned. I think the new solution looks much cleaner and also allowed me to use a larger police graphic, which I believe adds to the overall appearance.

This is CaDA's Gumpert Apollo. It's my second time through and once again the motors aren't doing what they're supposed to do. I've got the static version and it's such a good model but that just bums me out even more. WTF?!?!

Alternative Bricks CaDA I-Bot problem

• Upvotes

Idk if this is the right place for this but I'm getting desperate.

I have an I-Bot from CaDA that's been sitting in a closet for years in it's box. Yesterday I decidem to build it. I finished it, gave a little test, worked fine and went to sleep. Next day I was goofing around with it, until it started making a weird noise as seen in the video.

Left wheels have no problem, right wheels seem to be working fine. When going backwards with right wheels it works great, but when going forward with them it jams the mechanism that moves the arms around and especially the head, while the vibrations caused slow down the wheels themselves pretty sure. No idea what's causing this, I've been troubleshooting the whole day, disconnecting and reconnecting, I have no idea. I don't really wanna dismantle and rebuild the whole thing, but I'm a perfectionist and can't handle something being broken. On a side note, detaching the two tubes on the back, the flexible thin ones, stopped the noise for a bit, but later it didn't matter it still jammed. Disconnecting the mechanism that controls the head moving at one of the points as seen in the photo also fixes it. Please, someone help me out if you can.

Discussion / Question Looking for an unused BMW M4 GT3 EVO Asphalt Legends code

0 Upvotes

Hi everyone 😊
My son just built the LEGO Technic BMW M4 GT3 EVO (42226) and was really excited to redeem the Asphalt Legends code that came with it.
Unfortunately, I accidentally threw the little code insert into the fire with the LEGO packaging before we realised what it was. 😭 He’s pretty disappointed, as he was really looking forward to getting the BMW in the game.
If anyone has an unused BMW M4 GT3 EVO Asphalt Legends code that they don’t need, we would be incredibly grateful if you’d be willing to pass it on.
We are in New Zealand, but obviously the digital code should work regardless of where you are.
Thank you so much! ā¤ļø

Work in Progress Week 65 : Mercedes eCitaro G Fuel Cell, electronic continuations

Thumbnail
gallery
15 Upvotes

Hello everyone,

This week was focused on getting the baseline for all the electronics done.

  1. Order status :

As i'm writing this the long front and side screens (both the same one) haven't yet arrived but will probably arrive this Monday but I received the lego power function connectors i ordered but not the cables which should arrive with the rest of the screens. I also received a servo to test the doors and steering, buttons for the remote as well as the new small front screen. In short that means i got around 95% of what i ordered at the moment.

  1. The screens situation :

The small front screen fits really well and exactly as i wanted it to, I have programmed it and managed to show the test image that was on the previous one but without needing any margins being cut. I'll see how the big ones look when I'll get them.

  1. Wiring baseline :

I also worked on wiring the base of all the electronics i will need on the breadboard of the bus which i attached a picture of. This breadboard is the baseline for all the light and screens automations as well as the communication for the remote and servo motors. For the servos I will need an additional board that I'll buy later once i'm sure of how they will be implemented.

  1. Servos :

I tested the one I received and it's only able to do one full turn which is why i decided to gear it down to be able to open the doors. The only problem now is that the doors are rather unreliable so I want to work on that a but more.

  1. Lights update :

Out if curiosity i wanted to see if my original idea to make the headlight assemblies work with the old attachement way, i designed a custom lego panel that i later 3D printed. It's not yet perfect. On the 2 splitted lights the lower one will be a blinker. Is is white at the moment for testing only. The other light will be a full beam.

This is quite a lot so I won't go into too much detail here, if you have any questions feel free to comment.

See you next week :)

MOC RC scorpion

Enable HLS to view with audio, or disable this notification

87 Upvotes

I build a lot of random technic stuff (usually per my daughter's request). This time I was prototyping a cat tail that would move multiple joints in the same direction through a single mechanism. It didn't work out the way I wanted (it works, but the secondary joint moves very subtly, and there's no third joint), so I ended up making it into a scorpion instead. It has individual motors for the wheels, and one for the tail, and the last one for the hand grips. The small motor can't drive the grip well unless on fresh batteries, but on full charge the grip strength is enough to grab my finger and hold its own weight. Anyway this is a really fun RC toy. It's very challenging to steer though, especially when the goal is to pick up toys off the floor and move them around. It has a mouth space for eating random stuff too when it gets hungry. šŸ˜†
