Say Yes to the Dress(ta)


This is a Dressta TD-25M bulldozer, and it’s about as good a Lego creation as you’ll see this year.

Built by Bricksley of Flickr, this incredible model blends Model Team aesthetics, PoweredUp motors, pneumatics, and Mindstorms to create a perfectly working 1:18 replica of the Polish crawler-dozer.

A LEGO Mindstorms hub can be operated by an Xbox controller to remotely drive the four PoweredUp motors that power both the tracks and the pneumatic system that provides movement the front blade and rear ripper, whilst LED lights and even a working horn and back-up warning sound feature.

It’s an amazing build and one of which you can see more at Bricksley’s Dressta DT-25M’ album on Flickr – Click the link above to say yes to the Dressta.

Dozing Cat

Cats are best when they’re dozing. Because then they’re not scratching something, killing wildlife, or crapping on your lawn.

Dig at cats in general complete, we can tenuously link to this Cat ‘dozer, a Caterpillar D6N LGN as built by regular bloggee Damian Z. Building instructions are available and there’s more to see of his wonderfully detailed creation on Flickr via the link.

Crazy Cat

This magnificently obscure vehicle is a 1910s Holt 75hp Caterpillar, a part-track tractor produced by the company that would later become the world-renowned Caterpillar brand. Powered by a 23 litre 4-cylinder gasoline engine, and weighing 10 tons, the Holt Caterpillar was quite fantastically slow, but was reliable and could haul almost anything almost anywhere.

With war raging in Europe and limited photos of the newfangled British ‘tanks’ operating in the mire, Holt even converted one of their 75hp Caterpillars into a ‘tank’ as a PR exercise to parade to U.S citizens with the phrase ‘America First’ painted on it, dubiously attempting to take credit for something they had nothing to do with. Make your own Trump link…

This charming replica of the Holt 75hp Caterpillar (in conventional tractor form) comes from previous bloggee Nikolaus Löwe (aka Mr_Kleinstein), and includes BuWizz controlled drive and steering, as well as accurately reflecting the bizarre exterior of the original.

There’s more to see of Nikolaus’ Holt 75hp tractor at his photostream via the link in the text above, and if you think this is weird here’s a bonus link to the ‘tank’ version, which might just be the oddest thing you see today….

What a Knob

A lot of knobs. No, not TLCB Staff, nor the summation of your Mom’s summer, but this properly mechanical Technic skid-steer excavator by Flickr’s Thirdwigg.

There are knobs for the boom arm, knobs for the bucket, knobs for the blade, knobs for the turntable rotation, and very possibly other knobs we’ve not spotted too.

It’s a wonderful reminder of old-school mechanised Technic, and you can see more of all the knobs in question at Thirdwigg’s ‘Skid Excavator’ album on Flickr. Click the link above for more knobs in one place than your Mom’s beach-house parties.

Flattening Alternative

TLCB staff know to wear shoes in the office. No, the Elves don’t make that sort of mess, but their shenanigans do make barefoot walking of the halls hazardous. Today, this TLCB Writer forgot that rule.

A sensation of something both gloopy and slightly crunchy underfoot drew a sigh and a weary look down, upon which the Elf, smeared into the carpet, became apparent. Another sigh.

And another Elf too, as a second was in a similar predicament a few yards down the corridor.

Further again, and the strange sound of a motor whirring followed by repeated crunching could be faintly heard. A third sigh.

Rounding the corner and the source of the smushings revealed itself; a large unusual-looking tracked vehicle was stomping upon a flattened Elf with a stabilising foot, much to the glee of the Elf at the controls.

Said controls were quickly grabbed and we could determine the steps the Elf had taken to mete out violence on its colleagues.

Firstly, they were run over, thanks to the skid steer of the two suspended and motorised tracks, before – admittedly rather cleverly – the Elven psychopath at the controls compounded the misery of the victim by either stomping upon them with the vehicle’s stabilising legs or dropping a brick-built ‘diesel generator’ onto them via the fully motorised crane.

Which – Elven carnage aside – is seriously impressive. TLCB Master MOCer Nico71is the builder behind this curious (and stunningly engineered) creation, which is constructed only from the pieces found within the official LEGO Technic 42100 Liebherr R 9800 Excavator set.

All seven Powered-Up motors from the set have been redeployed to the purposes above; with remote control drive and steering, crane rotation and two-part elevation, four stabiliser legs, plus a motor spins a piston engine for added realism.

All of that can be controlled via the LEGO Powered-Up app, and if you’d like to convert your own 42100 Liebherr R 9800 set into an unusual Elf-smushing machine you can, as Nico has made building instructions available too.

There’s much more to see at Brickshelf, Nico’s excellent website or via the video below. Take a look whilst this TLCB Writer cleans the corridor carpet. And puts on some shoes.

Clearly Roving

2022’s Febrovery is drawing to a close, in which Lego builders from around the world have united in their creation of other-worldly transports. Today we round out the roverest of months with four intriguing space-based builds, each of which has deployed a few of LEGO’s more unusual pieces in the pursuit of roving brilliance.

First up is Robert Heim‘s ‘Spaceport Fire Rover’, which features so many LEGO pieces of which we know nothing it’s making us doubt we can do this job. The wheels look like cupcake cases and the rotating cockpit appears as if it’s made from a kid’s sand bucket. We have absolutely no idea what sets they’re all from, but you can find out more at Robert’s photostream via the link.

Next we have martin.with.bricks‘ impressive eight-wheeled rover, which actually looks rather like something we could well see in our lifetime. A determined-looking mini-figure sits at the controls inside the same clear buckety-brick cockpit, whilst a minimalist brick-built lunar surface passes beneath the tyres. Centre articulation and an opening rear hatch add to the fun and you can see more of Martin’s rover on Flickr at the link above.

No longer used as the cockpit, but still featuring prominently in the design, Frost‘s colourful ‘Biotron Corp Spaceplant Relocation Rover’ utilises the same transparent buckets, this time for some sort of lunar re-wilding project. A trans-lime half-dome continues the funky cockpitting however, and there’s more to see of Frost’s space-based conservation via the link above.

Today’s final Febrovery creation takes a rather more utilitarian approach, and is very possibly the reason that Frost’s ‘Spaceplant Relocation Rover’ above is required. Andreas Lenander‘s ‘Dome-rover’ is smoothing its way across a lovely brick-built moon-scape, thanks to some genius tracks and a wonderfully pink classic spaceman sealed within a transparent orb. Andreas has used said orb in other cunning ways during Febrovery ’22 too, and there’s more to see of this and his other Febrovery builds at his photostream via the link above.

And that completes our Febrovery 2022 round-up, which took on quite a transparent theme this year. Febrovery will be back in 2023, but until then there is still a whole month to go in TLCB and Bricknerd’s ‘Festival of Mundanity’ competition, in which we’re looking for vehicles that are rather more earth-bound. What better way to move on from other-wordly oddness than a white Toyota Corolla looking for a parking space…

LEGO Technic 2022 | Set Previews! (Pt.2)

It’s been two months since the survivors of the select group of Elven ‘volunteers’ tasked with uncovering the new-for-2022 Technic sets returned from The LEGO Company’s HQ. We were down a couple of Elves of course, but you don’t make an omelette without a few Elves getting eaten by the guard dogs. Or something.

But no! Some eight weeks later three very bedraggled and rather thin Elves have made it back! Which means we have three more brand new Technic sets to share with you – huzzah. So without further preamble, here are the final* three new additions to the 2022 Technic line-up.

42140 App-Controlled Transformation Vehicle

The first is this, the ‘Transformation Vehicle’, which is a title both rather meaningless and wrong, as it doesn’t transform at all. What it does do is flip upside-down, revealing another body underneath, and we’d be lying if we said we weren’t properly excited about this!

Controlled by LEGO’s new Control+ app, 42140 can skid steer after the cat via your mobile phone, and if you accidentally turn it over against a chair leg, you can simply carry on using the blue body rather than the orange one shown here, thus continuing the pet torment.

It doesn’t appear as if 42140 does anything else, but nevertheless it looks great fun, although – full disclosure – we may have been influenced heavily by adverts for the Tyco Rebound as children. And yes, toy commercials really were like that in the mid-’90s.

The 42140 App-Controlled Transformation Vehicle includes 772 pieces, is aimed at aged 9+, and is expected to cost around $130/£115 when it reaches stores in March. Your cat’s definitely going to meet its match.

42133 Telehandler

From $130 cat-chasing devices to a 143-piece pocket-money starter set. The 42133 Telehandler is one of the smallest Technic sets in the 2022 range, costing just $13/£9, and – as starter sets go – it’s perfectly good. There’s working steering (although at the front rather than the rear), and a boom that can raise/lower mechanically too, whilst keeping the fork level. A decent entry point for the Technic range.

42139 All-Terrain Vehicle

The largest of the final three* sets to join the 2022 Technic line-up is this, the 42139 All-Terrain Vehicle. We’d call this a ‘quad’ in our home nation, which of course it isn’t as it has six wheels. All six are suspended, with a pendular axle on the front and shocks at the back, there’s working steering via the handlebars, a tipping load bed, winch, and a piston engine with a high/low range gearbox.

Which all looks rather good we think, although the stickers are probably unnecessary, plus there’s a chain-saw and a few logs so you can pretend to be a lumberjack.

42139 is aimed at ages 10+, features 764 pieces, and is expected to cost around $80/£65 when it reaches stores. It’s also probably our favourite of the bunch. Unless we want to chase cats.

*You may have noticed a few asterisk symbols in this post. That’s because these aren’t quite the final three new Technic sets. There’s one more to come, and it might just carry both ‘McLaren’ and ‘Formula 1’ licensing….

Green Slopes

Technic creations don’t have to be ginormous piece-hungry behemoths. Sometimes small and simple can be good, as proven here by Zsolt Nagy’s ‘Mini Snow Groomer’. Stick to the green slopes via Eurobricks or Flickr.

Surprise Squashing

‘Huh…’ thought this TLCB Writer as he entered the office today. The cause of the casual surprise was a weird yellow vehicle, trundling up and down the corridor with a gaggle of happy Elves in the back.

Seasoned readers of this crumbing ruin in the corner of the internet will know such peaceful interaction between TLCB Elves is seldom seen. The Elf at the controls was smiling, the Elves in the back were smiling, and for a moment we thought that 2022 could be the dawning of a harmonious new era for our little workers.

Was it balls.

The Elf at the controls, knowing its find was too slow to mete out any smushings, had ingeniously offered its colleagues rides in the back. After a joyful excursion around the TLCB Towers the aforementioned little psychopath then deployed the model’s tipping bed, tumbling its Elven cargo onto the ground before immediately reversing over them.

To compound the smushing it then spun the vehicle on top of those trapped underneath via the skid steer system, smearing quite a few into rather artful arcs in the carpet.

Of course the controls were swiftly were taken away, a meal token and yellow Smartie begrudgingly awarded, and the victims either patched up on site or taken to the ‘Elf Hospital‘, depending upon their triage assessment.

We’re really not sure how we’re going to get all the Elf bits out of the office carpet, so whilst we figure that out you can check out Arie’s Morooka MST 2200VD tracked dumper with SBrick control, twin L Motor drive/skid-steer, and linear-actuator operated tipper at both Eurobricks and Bricksafe.

Perhaps we should install lino.

Building Big

Really, really big.

The human in the above picture is Beat Felber, a Lego builder of gigantic proportions. His models we mean.

Surrounding Beat are ten spectacular fully remote controlled pieces of mining equipment, many of which have featured on these pages over the years, including the Komatsu D575A-3 Super Dozer, the Marathon LeTourneau L-1200 loader, the Marion 204-M Superfront cable-operated mining shovel, the Terex 33-19 Titan mining truck, and the astonishing Marion 5760 ‘The Mountaineer’ 2,750-ton mining shovel

Beat’s assembly is even larger and more impressive than your Dad’s collection of speciality magazines, and we suspect it makes Beat more than capable of tunnelling underneath his own house should he choose to.

Head to Beat’s photostream via the first link for a closer look at the jaw-dropping image above, and you can check out some of the individual models pictured within it via the links in this post or via the search function on this page.

Twiddling Knobs

We like a good knob twiddle* here at The Lego Car Blog. Get your minds out of the gutter – we’re talking hand-powered mechanical functions.

This is one such creation imbued with knob twiddling goodness, and it comes from previous bloggee M_Longer, who has repurposed the pieces found within the LEGO Technic 42121 Heavy Duty Excavator set to create it.

Loosely based on a JCB skid-steer loader, M_Longer’s 42121 alternate utilises a pair of knobs to mechanically control the arm and attachment tilt, so you’ll need to play with the knobs a bit before you can get forking. Ask your Mom.

There’s more of M-Longer’s B-Model to see at the Eurobricks discussion forum, where links to both further images and to building instructions can also be found. Twiddle your knob via the link above!

*Except in this case. As it’s ridiculous.

Rope & Bucket

Today’s post sounds like an English pub, but it is in fact a fully operational recreation of the Caterpillar 7295 rope excavator, as built by Ivan_M in a spectacular 1:40 scale.

Inside Ivan’s model are six Power Functions motors that drive the tracks, superstructure rotation, and the winches that lift, extend, and open the bucket.

It’s a complicated movement but one that Ivan has managed to replicate beautifully, with his model demonstrating some of the most impressive action on video you’ll see today. Ok, we can’t guarantee that – the internet’s a big place – but it’s nevertheless properly good.

There’s more to see of Ivan’s stunning Caterpillar 7295 rope excavator on Flickr and at the Eurobricks forum, plus you can watch that impressive action in the ace video below!

Dananananana Bateman!

This is a Bateman Assault Bridge Carrier, an experimental tank-bridge-laying-combo based on the excellently-named ‘Medium Dragon’ Mk.1 artillery tractor that was trialled by the British Royal Engineers in 1926.

It’s one of the more obscure vehicles to appear here then, and it’s been recreated brilliantly by Tarix819 of Eurobricks in a colossal 1:8 scale.

Weighing almost 10kgs, Tarix’s creation features two coil-sprung tracks, each with its own mechanical tensioner and independently powered by an SBrick and three XL motors.

A working V8 engine lives within the armour, and a functioning searchlight is able to light up the obstacle ahead in need of crossing.

And cross an obstacle the Bateman can, as Tarix’s model can deploy the huge bridge mounted on the top of machine. The real Assault Bridge Carrier relied on hand-powered winches (which are also recreated here), but Tarix’s build utilises a Power Functions Medium Motor to complete the model’s suite of remote control functionality.

It’s a monumentally impressive piece of Lego engineering and you can see how Tarix has done it at the Eurobricks discussion form here, and via the brilliant video below.

Brick Built Bucket

LEGO’s new Technic 42131 App-Controlled CAT D11 Bulldozer set revealed here earlier in the week is a spectacular (and spectacularly expensive) way to push LEGO pieces around your floor.

Of course the online Lego Community has been building super-sized RC bulldozers for some time, and this magnificent Liebherr PR 776 by Flickr’s Dawid Szmandra is one of the best we’ve seen yet.

With four motors, a Mindstorms EV3 for control, and perhaps the best brick-built bucket we’ve ever seen, Dawid’s creation gives LEGO’s 42131 set a run for its (considerable amount of) money, and it’s a creation you can build for yourself as he’s made building instructions available too.

There’s more of the build to see at Dawid’s ‘Liebherr PR 776’ album on Flickr, where a links to building instructions and even to the custom decals can also be found.

Technic 42131 App-Controlled CAT D11 Bulldozer | Set Preview

Household pets and TLCB Elves don’t usually get on. From October 2021 however, we expect they might share a common nemesis; this is the brand new LEGO Technic 42131 App-Controlled CAT D11 Bulldozer. All 3,854 pieces of it.

Measuring 57cm in length and 37cm wide, 42131 brings the Caterpillar brand into LEGO’s burgeoning array of official partnerships – alongside equipment manufacturers such as Volvo, Claas, and Liebherr.

Four ‘Powered UP’ motors and a Control+ hub enable the set to be controlled via your mobile phone, with the huge yellow tracks, blade elevation and tilt, and ripper height all powered and remotely operable.

Those yellow tracks are new for 2021 too, making their debut on 42131, and featuring a tightening/loosening mechanism that we expect will make them highly sought after for builders’ own tracked creations.

A working piston engine complete with details such as brick built turbo-chargers, realistic (and – we must admit – rather excellent looking) decals, and a high level of visual exterior detailing including rails, ladders, exhausts, and lights, make for very impressive looking set, and one we expect will become mighty popular.

Aimed at ages 18+, the new LEGO Technic 42131 App-Controlled CAT D11 Bulldozer is expected to cost around £420, which – much to the relief of our Elves – is comfortably outside TLCB’s budget. If it’s within yours you can get your hands on all 3,854 pieces from October 2021, and your cat will never be able to relax again.
