  1. I was quite pleased with the 2020 H1 line-up as someone who prefers the small to mid-range sets. It was nice to see the pull-backs had enough pieces for a proper B-model and some original and playable models in the smallest sets. It got me wondering if any of them could be built as C-models of existing sets. It turns out the Container Yard in combination with the Arctic Truck (42062+42038) have all the pieces need for a Beach Buggy, and the Chevrolet Corvette ZR1 (42093) plus a pullback motor can give you a Racing Truck.

    [C-model] Yoda's Mech (alternate build 75168)

    I got Yoda's Jedi Starfighter a while ago as a gift from a friend. I normally make c-models of Technic sets, so initially I wasn't sure what to do with this after building the main model (other than a Tulip!). This set has a range of Technic pieces so it was familiar but also a nice change. There no ball joints that are usually associated with Lego mechs but I thought I could still manage a range of motions. I built the frame first using the Technic pieces before adding the decoration. In the end I managed to create knee, hip and shoulder joints and the model is reasonably stable and pose-able. The Mech is equipped with missile launchers, force blasters and can transform into a flying mode, allowing Yoda to soar over rough terrain. It can crouch down for easy access to the cockpit.I quickly settled on the design for the feet and arms which shaped the way the build turned out. The knee and hip joints were revised a couple of times before settling on the current version. The wings are actually an important part of the model to ensure it remains balanced.

  3. I'd like to share with a quartet of c-models which are based on A-models from 2018-19. There has been no model since the Racing Yacht and Heavy Duty Forklift that had that special something to make me want to buy it (the Car Transporter came very close). I typically stick to buying the low/mid range sets and now have around 20. I enjoy the challenge of C-model creation as you can see on bricksafe, and using Rebrickable.com I looked at which of the 2018-19 line-up I could enjoy the building experience for using bricks from my existing sets. I initially was going to make the First Responder from the Airport Rescue Vehicle but the similarities with the B-model for this set ruled it out. Turning the Racing Yacht into the Powerboat was a logical next step. I tried to follow the instructions for 42089 making substitutions and skipping sections as required. Once that was done, I went back over the model with the remaining pieces to try and find a way to complete it whilst keeping the vibe of the parent model. This process made me very familiar with the instructions for 42089 such that I tried again with the Heavy Lift Helicopter and Airport Rescue Vehicle. Having woken up my brain to the possibilities, I went back to Rebrickable.com to look for a bigger challenge. Comments in reviews about the chassis for the Rally Racer put me onto the 24 Hours Race Car being a good candidate. This followed the same basic process as before but this time need much bigger reworks. I often realised the piece I really need to complete the bodywork of the model had been used elsewhere in the chassis, and a swap would be needed. I'm pretty pleased with the outcome. This idea of recreating an A-model as a C-model is not new (https://rebrickable.com/users/klimax/mocs/ has a number of examples). More pictures of each model can be found on Bricksafe (https://bricksafe.com/pages/TheKitchenScientist). This version of the Rally Car has kept the suspension and HOG steering but lost the opening front/rear. I managed to add steering via the steering wheel. The brick built 3-cylinder engine is not linked to the wheels but turns with the propeller. Using a worm gear I was able to link the propeller to the wheels but there was no engine this time. This model had all the parts to recreate the engine/wheels/propeller functionality but lacked some of the panels needed to keep it power-boaty. As a compromise I took the arm mechanism from the Airport Rescue Vehicle and mounted in the extended boat.

    Pin Sorting Machine

    I would suggest a vibrating table feeder to move the pins to the colour sensor. Could something like the sail from the recent technic yacht give you a smooth deformable surface as an alternative?

    [REVIEW] 42079 - Heavy Duty Forklift

    I bought this set out of nostalgia for the forklift model 8835 which I enjoyed building as a teenager. When I opened the box and found instructions for the B-model, I built it first. It is a very nice build, not too much repetition, good use of parts and the tow-hook lift mechanism is very smooth.

    [MOC] Ocean Racer

    @TechnicSummse no progress since September. I barely got a replacement TC12 entry finished before a bunch of work/social commitments took over. Now the contest winners have been announced, I plan to get back to building.

    [MOC] Ocean Racer

    One of the aspects of the wacky races which I liked the most were the vehicles which were a mash-up, like the boat/plane and steamroller/tank. In that spirit may I present my prototype entry to the TC12 competition: Your eyes are not deceiving you, I have mounted the Ocean Explorer within the 24h Racer. Thanks to the standard LEGO sizes it is a perfect fit. Even better the HOG steering in both models was in the same place. I removed the boat rudder and the control on the rear of the tower now steers the front wheels. I had to lock out the suspension due to the extra weight and the car rear and boat tower required some rebuilding. It still has the crane functions, motor in the racer and the 3 drive points for the functions of the 24h racer. I hope to use these to add more wacky features. Currently the only weapon is the bulb of the boat hull for ramming other racers. It took an evening of building to blend the models whilst retaining their functionality.

    [TC12] Kid Cash's Caster Cube

    After my previous attempt at entering this competition was ruled out, I made sure my new idea wouldn't suffer the same fate before starting to build. So what makes this entry wacky? All the wheels will be mounted as casters to give omnidirectional steering. Like a hovercraft the vehicle will be blown along rather than having driven axles. As is my creative strategy at the moment my build will be limited to the sets below. I am sticking to the pocket money range for my parts. This also keeps the larger sets free for my other build. It remains to be seen if I can manage casters on all sides of the vehicle. I'm thinking only two wheels on each face need to be casters as long as the remaining two have independent axles.
  9. 25. Kid Cash's Caster Cube Kid Cash has been brought out of retirement, after a successful career racing for Shell in the 80's, to compete in the Wackiest race this year. The vehicle is of lightweight construction and has been designed to out-race rather than smash the opposition. HOG steering and flight. Fan propulsion. Slicks for street racing as well as a separate set of all terrain tires. The wheels are caster mounted for better manoeuvrability. Always up driver's seat with front & rear lights. Can flip the fans from back to top (flight) or front (rapid reversing) by rolling the entire vehicle. The video below shows how the Wacky features allow it to fly over obstacles and up cliff faces. There is space in the cube for a trusty backup vehicle. It is built from the LEGO Technic pocket money sets 42010, 42011, 42020, 42026, 42033 & 42044-47.

    [TC12] Kid Cash's Caster Cube

    With the deadline approaching I have found time to edit a short video highlighting the main features:

    [TC12] Kid Cash's Caster Cube

    I think it is close to being finished. I've reworked each face to make them more distinct. The engine now has a fuel tank and quad exhausts. The blades now rotate in opposite directions to enable a hover mode, to get out of trouble. It also means I can drive straight up walls and cliffs. The third mode is back to being offroad or rapid U-turn depending on the situation. There is potential for a bit more greebling but I think the concept is complete. It is clearly a Racer and has some interesting features. Much to my surprise it ended up being the less popular sets that have contributed most to this model (stunt plane, record breaker, twin rotor helicopter, hydroplane racer).

    [TC12] Kid Cash's Caster Cube

    Thanks @Saberwing40k. That was how I originally built it, but it didn't look as pretty as both turning the same way. @mocbuild101 as you say, does it matter? I guess I was trying to give it a shred of believability.

    [TC12] Kid Cash's Caster Cube

    Finally made progress and got the driver and propulsion system mounted. As you can see I have reworked some of the colours to give each face a more consistent feel. The rear outriggers prevent the vehicle from rolling on its side. If trouble is spotted ahead the front brakes can be applied to flip the vehicle onto it's face. The driver seat also pivots and the racer can now operate in heli-mode and fly over the trouble. I'm still trying to decide if I should make the third mode all-terrain by swapping the top set of slicks for off road tires? Any helicopter experts out there tell me if the blades should rotate in the same or opposite directions?

    Lego EV3 Program blocks help

    It should be a pretty similar program to the ones for finding the ir beacon. I would suggest you use a couple of array blocks to hold data from the light sensor. Pick a random direction (left or right), lock the steering, drive forward and collect a dozen readings to one array. Back up the same amount as you went forward. Set the steering to opposite lock and repeat into the other array. Whichever has the highest brightness is the direction to head. If no flashlight is detected perhaps steer a random direction to turn 90 degrees and repeat. I guess you will need touch sensor to locate the wall. The light sensor can also do this to give front and back coverage.

    Mindstorms EV3 reference guide?

    This is probably one case where what you are planning to build will drive the learning. I have found if I can write it in suedo code then I can translate to EV3 (or realise it is beyond what can be done with the supplied software). Blue Angel on YouTube has a good series of videos. Also the PC software tutorials are helpful in introducing the blocks logically.

    Need some help with programming LEGO mindstorms EV3

    The Programmer app or PC software will be required for what you are asking. You can create a loop that checks if the colour sensor has detected red, stop the motor, play a sound and then end the program. Once the program is on the Brick you can start it and also use remote control (IR) not sure about Bluetooth.

    [MOC] Ocean Racer

    There have been a few issues with the blending process and I had to let the model sit for a week whilst waiting on a solution. First I tried adding the rotor blades but the balance wasn't right. I had tried to include the tail section also but this didn't help. The solution seems to be to chop out the orange tinted sections and restore the control tower rather than use rotors. The deck crane had to go to make enough space. Now the real hard work begins. I need to restore steering, get the jaw working again and restore as much cross bracing as possible. It is the first thing to go in the blending process but in its current form the model is very fragile.

    [TC12] Kid Cash's Caster Cube

    The low profile tires have driven the next phase of this build. It may not look much different but the casters are now aligned on the non-panel faces. This has given the model a more defined front and sides. I had wanted to build a cube 30 studs to a side. This would have offered the driver a better view but I'm not sure it would be very strong. One of the things I like about this smaller design is the rigidity. You are indeed seeing my plan. I am working on this at the moment. Getting the balance plus style is not so easy. I was going to mount the fans in a gyro housing inside the cube with the driving seat in front. As other TC12 entries have found, such a mechanism takes up lots of space. I will mount the driver inside the cube and think again about how the fans might work.

    [TC12] Fire Ant - One-minute pitch

    Looking at the rear of the vehicle it seems like it could perhaps have a manual wheelie function, or fold up so the wheel base shortens. You have a good eye for clean lines.

    [TC12] Kid Cash's Caster Cube

    A short building update. There were sufficient 15 stud beams in the sets to create a cube. My original idea was going to be more bowl like. It was to be made of triangles with a caster at each point. In the end the parts didn't speak to me in this direction. A range of casters have been fitted to four faces. The low profile tires allow for panels and lift arms to be used as axle mounts. Having two fixed, two rotating casters is more stable and not much less manoeuvrable than four rotating. I think I may go with this design for all the faces.

    [MOC] Ocean Racer

    A few people have shown an interest in the building process, so for this blend I've taken some mid-blend pictures. The ocean explorer is now completely gutted. The deck crane was easy to relocate but I have lost steering control temporarily. I didn't get far into building the next model to blend before realising it was going to need some serious modding. The function I planned to use was right in the middle of the model. As you can see above the central section of 42052 is mounted where the control tower was. Above the bow is where the pf motor and tail section should be. I'm going to have to work out how to swap the tail structure for the cockpit. And as to the wacky function, that this blend provides? The bow now raises so it can take a bite out of cars in front.

    [EV3] Fully Automated Candy Warehouse

    Have you considered mounting a roller on one touch sensor in the tower? You could have a corresponding vertical track which kept the sensor depressed between levels but allowed it to spring out to signal a stop. This could have the added benefit of being able to count the 'clicks' so you know which position you are in. Speak of clicking, could you use an NXT sound sensor to sense/count clicks. Could the protective gear from the power functions provide the noise?

    [MOC] Ocean Racer

    I only have 420xx series sets that retailed for under £100. I also decided only to use those in the £40-100 range for this project, since they have similar geometry. I started collecting with the release of the Mindstorms EV3. I made ~15 models using only the 31313 set before I started getting technic sets as gifts (which opened the way to buying them for myself). I've used this building technique before in combination with the EV3. In some ways it's an extreme kind of C-Modelling. Can you retain the recognisable form of the original design whilst creating something definitely new? I actually bought 42023 specifically to build Diggatron in the picture above. As soon as I saw the set, I just knew what it wanted to be. It required hours of reworking the same bit of the model over and over to extract the pieces you need elsewhere but retain the functions. Other than the sensors, motors and power brick everything else is from the 42023 set.

    [MOC] Ocean Racer

    Hi @BrickbyBrickTechnic, I am glad you asked. I realize that having some kind of side arm or dumper are wacky features that other TC12 entries have used and so perhaps I need something more original. I hope the next blend will power the model to new heights. If that doesn't give it enough lift, I hope to add a bit of bite and perhaps something interesting to grapple with. I expect this next phase may take a week or two as I first need to reroute the crane controls and steering. Once the tower is removed I can then consider the blending process. Currently my blend target is not even built, so that alone will take a couple of evenings.

    [MOC] Ocean Racer

    Thank you @TechnicSummse, @msk6003 and @mocbuild101 for your encouragement. I have decided to continue and below is the result of blend 3 after adding the tracks from 42038 (Arctic Truck). It required a complete rebuild of the rear for the 4th time. It doesn't come out well in the pictures but I was able to retain both sets of rear lights from 42039. Single width tracks looked a bit small so I mounted them in pairs. They are on independent axles so the turning is unaffected. In profile the model reminds me of the Thunder Tank from Thundercats.
