[APP] BrickController2
JayDee96 replied to imurvai's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
It’s just a bug with dark mode that has been implemented in iOS 13. Turning off dark mode allows the app to appear properly. It seems to change the background to black but your app doesn’t adjust the text colour accordingly. -
[WIP] Ute supercar

I'm currently driving a 2017 Redline four door sedan in Light My Fire paint just as your inspiration photo. Your progress looks great. -
[APP] BrickController2

Gamepad support is implemented in iOS13 which is currently available in beta. Like AVCampos said, I assume Control+ might use some PID. Which could explain the behaviour of the XL motor when used in servo mode with the Control+ app, as the PID values won't be tuned to its heavier armature. Otherwise I am extremely impressed with your app. From downloading the app to driving the set took almost no time at all and was extremely simple to set up. -

I too am experiencing stuttering with the L motor in servo mode on iPhone with DualShock4 controller (iOS13 beta). Im using it in the stock 42099 set and with the model on the ground and load on the motor it works as expected. But with the model in the air the servo (L motor) repeatedly overshoots its position which results in jerky movements. And when returning to centre it overshoots and stops off centre. I think this could be a symptom of the motor trying to move at full power, even for small movements. Using the LEGO Control+ app the movement is buttery smooth. This seems to be because the LEGO app ramps in motor power over time. So for small movements or slow sweeps from left to right the motor is ramping up slowly to each encoder position, as opposed to full power until it hits each position, resulting in an over shoot and then over correction and ultimately a violent stutter. -
Price drop in Australia to match Disney Castle pricing (like other areas). LEGO just refunded me the AU$50 difference as I ordered on VIP release.

Two Powered Up motors for the 60198 cargo train engine
JayDee96 replied to legotownlinz's topic in LEGO Train Tech
I was testing this last night. Except I crossed over the input pins. I connected in1 to in4 and in2 to in3. This resulted in the motors turning opposite directions which is exactly what we need for trains with twin motors. It worked great. Using the 88010 remote if an input was given to both channels with the input pins shorted together in this way, the motors just stopped. There didn't seem to be any negative affect on the system. However this was tested with two 45303 Simple Medium Motors and only for a short time. Here is a small data sheet of the motor controller if anyone is interested: https://www.onsemi.com/pub/Collateral/LB1836M-D.PDF -
Limited Slip Differential
JayDee96 replied to Storext's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Typical mass produced LSD actually have clutch packs under heavy spring tension holding the centre gears to the centre casing, giving them the limited slip quality. This is why OEM limited slip diffs require special friction modifiers in the diff oil to stop the clutch packs "sticking" (causing a clicking or jumping while cornering), the friction modifiers actually reduce the LSDs effectiveness. So typical LSDs are never actually completely open, its engine torque that's helps the diff lock (as best it can), however if one wheel is in free air, no torque can actually be applied to the diff because there is no traction to apply it to. This is where the spring tension helps apply some torque to the non lifted wheel. I have built a makeshift LSD by inserting a thin rubber shim behind the three centre gears in a LEGO diff. However this virtually locked the diff and makes cornering as hard as with locked diffs, but will let the diff distribute torque enough to not break parts. I think the idea is sound if more effort is put into finding the correct thickness and friction of rubber used. -

Dawid recently posted the full configuration test to his youtube channel. Its nothing short of amazing. -
BrickTracks: R104 Switch Kickstarter is LIVE!
JayDee96 replied to coaster's topic in LEGO Train Tech
Im glad Kickstarter doesn't have a 'flexible funding' option like some other crowd funding platforms, but in this instance it'd be comfortable with it. Coaster seems more than committed to producing these track pieces and I assume if the kickstarter doesn't reach its goal it'll only delay the project, not stop it. If the goal isn't reached id be happy to preorder the switches from brick tracks and help the project that way. -
I know this is off topic to the post intention, but there is lots of good discussion here. At the risk of scaring off LEGO with third parties, I think releasing their protocol would be great for companies like Sbrick, and BuWizz. I have invested a fair amount into Sbrick and very much like their solution and the profile designer. It'd be perfect if those profiles could then run both LEGO PU and Sbrick. at the moment im on the fence determining if ill have to abandon one for the other. If I can run all my "old" PF stuff from an Sbrick and buy into the new PU system and have them work in harmony that'd be my perfect solution.

I can only echo what the others are saying and this is amazing. Your smaller models (if they can even be called that) are also outstanding. On your YouTube channel you’re pretty firm about not having instructions for any of your models, but I have seen members here help out many builders with producing and selling instructions. I have a big catalog of instructions im waiting for the space and funds to work through. So if your courisoty peaks you’re in the right place. -

Love how well you captured all the centre entertainment controls. -
I once found a modeller online that completely rebuilt the Bronx terminal in HO scale. All track hand laid, bent, filed and soldered. All the frogs hand built, ties laser cut and copper coated. Give me a moment and I'll supply a link. He had a YouTube series. Edit: links http://www.bronx-terminal.com - Blog - VideoTrack work is beautiful.

Having them stored away definitely isn't my ideal. Since having made my last post I have been inspired to make room and force them into a spot. I have no set budget currently so money out varies a lot, it stretches a lot further when not purchasing at retired prices though. Try to get what I can while they are still retail, even if they can't currently be displayed. My Town Halls I found in a local toy shop after being retired, had I properly missed them and had to pay what they go for now, it may be the only regular building in my XL modular collection.

Sets get retired too quickly for some of us to build everything we like. I too have a handful of sets I couldn't imagine passing up, but currently dont have space or time for. Seeing my twin Town Halls still in their box bothers me less than paying $700 plus for them when I have the space.
