Have had this turntable forever and just now got around to uploading pictures. it's a Technics SL-D202 I think, too lazy to go check. sounds decent, still working out some gremlins in the system though.
General View of the Llywernog Silver Lead Mine Museum at Ponterwyd near Aberystwyth in Ceredigion, Wales.
From left to right - the Jigger House, The Crusher House and the Mine Offices. Between the Crusher House and Mine Office is a waterwheel pit. It had been the intention to erect a Cornish waterwheel in this location which had been loaned by the Trevithick Society. However, it was not installed and taken to the site of the treatment floors of Snaefell Mine at Laxey, Isle of Man where it was erected as the "Lady Evelyn" wheel.

Llywernog Silver Lead Mine and Mining Museum is located close to the A44 road.
Known locally as Gwaith Poole. (Poole’s Minework), the original discovery of the mineral vein was made around the year 1742, during the reign of George III.
By 1790, two ‘adits’ or levels were being blasted into the hillside using techniques of hand-drilling and gunpowder charges. Both of those original tunnels are now accessible to visitors. One tunnel struck the ‘Main Lode’ of silver-lead ore (technically known as (‘Argentiferous Galena’) at a depth of 17m below the surface outcrop and a productive period of activity began. The other adit, driven further to the east was a disappointment, and cut only a minor lode with little or no ore visible. This tunnel now forms part of the ‘Miners Trail’ and is known as ‘Balcombe’s level’, named after James Barton Balcombe, Managing Director of the Llywernog Silver-Lead Mining Company in 1870.
Between 1824 and 1834, Llywernog Mine was leased (along with many others in the district) to Cornish ‘Mine Adventurers’, the Williams family of Scorrier House, Gwennap, near Redruth in Cornwall. This was the start of a long association between the Mining Districts of Cardiganshire and Cornwall that was to continue until the 1900s.
Astronauts from five space agencies around the world take part in ESA’s CAVES training course– Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills.
The six cavenauts of this edition of CAVES are ESA astronaut Alexander Gerst, NASA astronauts Joe Acaba and Jeanette Epps, Roscosmos’ cosmonaut Nikolai Chub, Canadian Space Agency astronaut Josh Kutryk and Japan’s space agency Takuya Onishi.
The three-week course prepares astronauts to work safely and effectively in multicultural teams in an environment where safety is critical.
As they explore caves they encounter caverns, underground lakes and strange microscopic life. They test new technology and conduct science – just as if they were living on the International Space Station.
The six astronauts have to rely on their own skills, teamwork and ground control to achieve their mission goals – the course is designed to foster effective communication, decision-making, problem-solving, leadership and team dynamics.

NGD_GD01 / "Genesis"
When you're as famous - or infamous - as the Nyrah Ghosts, whose engineering prowess produced the Fohrok and the Ghostblaster, it's only a matter of time before over-ambitious customers think money can make the impossible possible.
The Order of Mata-Nui, a returning customer, once placed a pretty tall order - an autonomous army made up of machines which, unlike the dull Vahki, can think for themselves, reason, and even learn by editing their own programming.
The weapon builders constructed a highly advanced machine, but struggled with the programming. They eventually devised a "drone-chain" concept, where the units would be networked and added to the network sequentially, and each new drone would learn from the experiences of the one before it. Unfortunately the system proved too complex, and the Ghosts failed in making it work. After several missed deadlines, the Order retracted the project, and instead bought 600 crates of Zamor launchers.
However, one among the Nyrah, who was more motivated by academic achievement than profit decided to continue developing the idea. The first unit, the "genesis drone" of the chain, was already build, so he decided to created a self-enclosed system requiring no further units. Eventually he succeeded, and the drone was given an adaptive program capable of dynamically rewriting itself. The unit was given a strict ethical subroutine, disallowing harm to be done against any innocents and a strong simulated sense of justice. Finally, the creator gave the unit a purpose - to observe and study living biomechanical beings to alter his program accordingly and achieve sentience - be become "alive".
By now, Genesis developed to a point where he's chosen a name for himself, and added certain beings to his list of high priority (something these beings insist on calling "friendship").
During his travels, he's helped several Matoran communities who didn't have their own Toa protectors, and strives to once have his deeds recognized with an honorary Toa title.
---
The build process for Genesis was spawned by an idea that came to mind while building another MOC, and I ended up tossing this guy together in a few hours as opposed to the usual ~1 month build period. There is plenty to improve on him, and when I get the time, I will.
The idea was grabbing a set from just before Bionicle G1 - a Roborider - and something just after Bionicle G1 - Hero Factory - and mashing them together with the goal of getting a result that is Bionicle-y.
Built off of my white pickup v2, this technical feature the addition of a Soviet DShK heavy machine gun in the bed. It is inspired by Toyota Land Cruisers used in the Chadian-Libyan conflict of the late 1980s. Please leave any thoughts or suggestions in the comments.
Here is my latest motorbike moc/ mod, you can call it whatever you like.
The goal of this project was to modify my old 8051 set and try to find a good match for my beloved knobbed tires from set 42007 and basically with the combination to transform it into something more classic – Brat/Tracker bike.
Let me clear it for you, I think that 8051 set is a good source of ideas and a role model of efficient, compact design.
I love how the original frame of the 8051 was constructed, so I didn‘t need to put a lot of effort in this component. Pretty much the same principle goes with the front fairing. Yes you may say that it can look quite weird with brat/tracker, but these bikes are made for customizing for a reason I guess. I like the original dual round headlight, so I didn‘t bother to change it.
I had to pick a different set of handlebars. I love the look of the old triumph bars. Here I tried to use the clubman bars instead of flat track handlebars that are highly used with the trackers.
Now lets get to the features of the bike. The bike features a [fake] inline twin engine with a chain drive, front and rear suspensions, a kickstand followed with some details. That is about it, no fancy features at all. Everything is tend to be Simple yet effective. You may already noticed that this bike has a bitfewer lego system bricks than in my previous ones, well that is because I wanted it to be an extremely solid model, knowing how sturdy the frame already was made. That‘s why my decision was clear, if I can‘t combine both technic and system together properly, I will try to use system bricks at minimum. I think I did a good job accomplishing both of these things. With that being said, the hardest component was non other then the tank.. You may wonder why? I guess I had too much different variants of how a proper tank should look, that‘s why I had to put some time, many resources (and nerves) to get the one I felt was the right.
This is it, I‘m glad I was able to sharet this build with you guys.
This was the original rear suspension for the Sports Car. Supple enough for the weight of the car. Provided a great base for the rear of the car. Linked with two trailing arms connected to the car to manage fore and aft movements, and Watt's Linkage (http://en.wikipedia.org/wiki/Watt's_linkage)to manage lateral movements.
I was quite pleased with the result.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The Yokosuka J1Y was a land-based interceptor for the Imperial Japanese Navy Air Service (IJN/大日本帝國海軍航空隊, Dai-Nippon Teikoku Kaigun Kōkū-tai) that was based upon a research aircraft and introduced into service during the final months of WWII. Work on the J1Y commenced at the Yokosuka Naval Air Technical Arsenal (海軍航空技術廠, Kaigun Kōkū Gijutsu-shō) during 1942 and 1943, in the midst of the Second World War. The J1Y was initially intended to test the benefits of different aircraft layouts in order to exploit the available engines’ potential further, albeit the aircraft had been designed from the start in a fashion that was suitable for combat and easily adaptable into a light fighter aircraft. It would eventually be developed into Yokusuka’s only fighter project.
The J1Y was an unorthodox twin-boom pusher configuration fighter aircraft. It featured a mid-mounted wing, a tricycle landing gear arrangement, and was furnished with heavy forward-firing armament. The fuselage was primarily composed of plywood for the forward section and aluminum throughout the aft section, in order to save critical war material. The advantages of the pusher design were of an unobstructed forward view for the pilot, while the armament could also be concentrated in the nose, so that most of the aircraft’s heavy elements were concentrated around the mutual center of gravity. However, a major drawback was difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades, and the tail surfaces posed an imminent danger, too.
The J1Y1 test aircraft was powered by a 700 kW (940 hp) Nakajima Sakae 12 engine. A pair of intakes in the wings’ roots ducted cooling air to the engine, which was mounted at the egg-shaped fuselage’s tail, as well as to a pair of oil coolers that were buried in the thickened wing roots. Despite the aircraft’s tubby shape, it was a very clean design with an excellent weight distribution.
During the ensuing tests and flight trials in late 1943, the J1Y1 proved to be superior to the comparable Mitsubishi A6M2 “Zero” in many respects, so that the Imperial Japanese Navy Aviation Bureau (海軍航空本部, Kaigun Kōkū Hombu) became interested enough to eventually order a fully capable combat aircraft variant in early 1944: the J1Y2.
Development of the J1Y2 lasted until mid-1944. Outwardly, the aircraft differed only slightly from the J1Y1 test aircraft, of which four had been built. The internal structure was strengthened, esp. around the engine mount, because the fighter version was to be powered by the Mitsubishi Kinsei Model 48 radial engine which delivered 1,080 hp (810 kW). Since this engine had a slightly bigger diameter, the tight cowling had to be modified and now featured small bulges for its fourteen-cylinder heads, creating a characteristic ring of small bumps around the rear fuselage. The dorsal carburetor air scoop had to be enlarged, too.
The J1Y1’s four-blade propeller was replaced by a six-blade propeller – a measure that was necessary to convert the engine’s raised power output into sufficient propulsion, while exploiting the limited possible propeller disc diameter between the tail booms and keeping sufficient ground clearance.
Armor plates were added to the nose section and behind the pilot’s seat, but protection remained relatively light. In order to extend the J1Y1’s limited range of only 750 km (470 mi, 400 nmi), two additional 150l fuel tanks were added to the inner wings behind the landing gear wells, partly extending into the tail booms, even though they were not self-sealing like the main fuel tank behind the cockpit. Tilting air brakes were installed on the wings, enabling the J1Y1 to manoeuvre into a stable firing position behind slower aircraft. Armament consisted of a pair of 20 mm Type 99-2 cannon, flanking the front wheel well, supplemented by a pair of 7.7 mm (.303 in) Type 97 machine guns, which were rather intended as spotting rifles: they fired tracer rounds with the same trajectory as the 20 mm rounds, and gave off a flash and puff of white smoke on impact, so that 20 mm ammunition could be saved. Upon IJN introduction in August 1944, the J1Y was christened “Akaei” (アカエイ, “Stingray”). The Allied reporting name was "Ron"
However, teething development problems stemming from the Kasei engine cooling system and the main undercarriage members led to a slowdown in production. And when the Boeing B-29 Superfortress appeared, the J1Y2’s performance, esp. at height, was not sufficient anymore. Being not suited for high-altitude operations, and lacking internal space to accommodate a turbocharger, the IJN’s interest in the aircraft waned and resources were rather allocated to more promising types like the Mitsubishi J2M, despite its development problems, too. However, the J1Y2’s heavy gun armament supplied effective firepower and the use of dive and zoom tactics allowed it to score occasionally. It was also a very agile aircraft, esp. at medium altitude, so that production switched in January 1945, after 75 J1Y2s had been built, to the J1Y3.
The ultimate variant of the “Akaei” featured a new, even more powerful Mitsubishi Kinsei 62 engine with 1,163 kW (1,560 hp). Outwardly, this variant differed from its predecessor by a different exhaust arrangement: instead of the J1Y2’s two exhaust pipes, the J1Y3 featured individual exhaust, hidden under seven aerodynamic fairings, in order to exploit residual thrust and therefore further improve performance – resulting in even more bumps and fairing around the engine cowling. For the more powerful engine, and also because of cooling problems, the carburetor scoop was enlarged even more, so that an auxiliary cooling intake could be integrated.
Even though the armament nominally remained unchanged, supply shortages and field modifications in order to lighten the aircraft saw many J1Y3s with only two Type 99 cannons installed and the empty machine gun ports faired over. Some J1Y3s also carried gun 13.2 mm (.51 in) Type 3 heavy machine guns instead of the cannons, becoming designated J1Y3a. Due to ammunition shortages, some machines were converted in field workshops to this standard, too.
The J1Y3 arrived at IJN units in March 1945, but only a few were operational until the end of hostilities in the PTO, probably only around 40 aircraft were eventually delivered.

The kit and its assembly:
This build followed a spontaneous inspiration, and it became another contribution to the “in the navy” group build at whatifmodlers.com in early 2020. I actually had the Vampire kit already stashed away for a while, and the plan to convert it into a propeller-driven aircraft with a radial engine and a pusher configuration à la Saab 21 had been there – but I lacked an idea for an operator, so that I could build the background story around it. With the “in the navy” theme, it suddenly clicked – why not the IJN? The Vampire is a rather compact and slender aircraft, so there’s IMHO some Japanese “style” in the design, and after the torturous build of HMS Cerberus I wanted some kind of relief.
The Vampire kit is the vintage Heller mold from 1979, but actually in a mid-Nineties Revell re-boxing. Like many other Heller kits, it comes with raised panels, but detail is sufficient (nice dashboard, landing gear is O.K., and the kit comes with separate air brakes) – the molds seem to be a bit worn, though, I guess a “true” old Heller kit is more crisp and would be the better choice.
At the core of the conversion plan was the implantation of a radial engine in place of the jet exhaust. I found a donor part from a Hobby Boss MC.200 Saetta – a bit vintage, but it had the right diameter and I actually liked the ring of bulges on the cowling. Internally, a styrene tube adapter was added for a freely spinning propeller.
While adding a prop to a jet seems to be an easy task, the real challenge behind such a conversion are the many other changes that have to be made to the airframe. This includes a (considerably) longer landing gear and the respective wells, but also the tail surfaces. There’s also the question how the new radial engine actually breathes, where exhausts can be located, and a cooling system is necessary, too.
Work started with the search for new landing gear struts, and I also used different wheels – for instance, the main wheels come from a Hasegawa F9F Panther, while the front wheel comes from a Frog He 162 and is probably 35 years old(!). In order to make the longer struts fit into the airframe, I elongated the wells in the wings towards the fuselage, so that the track width was reduced – but with the Vampire’s small airframe and original wide stance, this was no serious problem. From the inside, they were faired with styrene profile material, and the extended covers were scratched – esp. the parts for the wings, with their bulges for the tail boom tips, were fiddly.
In order to move the overall look a bit further away from the Vampire, I completely changed the fin arrangement. The original, rounded and rather small fins and the bullet-shaped fairings that hold the stabilizer outside of the original exhaust blast were deleted. Once the wings and the tail booms were added to the fuselage, the stabilizer was mounted between the booms, in a slightly lower position. For the new fins I wanted a layout that would, beyond a more squarish shape that would better match the wings, protect the propeller. Therefore, I used stabilizers from a KP Yak-23; each was cut into two pieces, tailored further to match the rest of the aircraft, and glued in positions above and underneath the booms. Looks quite weird, as if the aircraft had been designed upside down, but it’s a rather pragmatic solution that has already been used on some pusher designs in the past.
The six-blade propeller was scratched from a spinner, carved from a thick piece of sprue, plus a metal axis and six single blades that were taken from the rather wacky one-piece propellers of Airfix’s Ki-46 kit.
Hollow steel needles were used as barrels for the Type 99 cannons in the lower fuselage.
Painting and markings:
Once more, a rather conservative approach – and the IJN was not creative when it came to liveries. Almost every aircraft carried a typical dark green over light grey scheme, with minimal individual markings or tactical codes. I wanted to stay true to this concept but decided to simplify the scheme even more since this would be a late-war aircraft, pressed into service under rather dire supply circumstances. This resulted in a NMF livery (basis is Tamiya XF-60, which turned out soemwaht grainy, plus some Polished Aluminum Metallizer from Humbrol on top), with only the upper surfaces camouflaged with IJN Green (ModelMaster) without primer underneath, resulting in a somewhat flaky and worn look. Since they are rather slender, the tail booms were completely painted in IJN green, too.
The yellow ID markings on the wings’ leading edges were created with decal material (TL Modellbau), the cockpit interior as well as the landing gear wells were painted with a mix of silver and blue, mimicking the typical “aodake iro” protective clear lacquer of Japanese IJN aircraft. The struts were painted black, according to A6M museum exhibits. The propeller blades ware painted in a red-brown primer, a mix of Humbrol 160 and 180.
Markings were taken from a PrintScale Yokosuka N1K2 decal sheet and mixed from two aircraft. Placing the fuselage hinomaru was tricky – the natural choice would have been the tail booms, but they’d be very small, so I rather put them on the fuselage under the cockpit. With the individual aircraft number added to the meatball, it looks now like a racing aircraft, though...
Finally, the kit received some soot stains and dry-brushing with aluminum, and everything was sealed with semi-gloss acrylic varnish from Italeri - even though the result is a little too glossy for my taste, but I left it that way.
A rather quick build, but structurally not much from the Vampire was changed. The new engine was relatievly easy to integrate - the other small bits like the fins, the propeller and esp. the landing gear took more time. The result looks quite odd - the whole thing has also a certain German touch? Could have worked well with a BMW 801 engine, too!
