The Jackup Neptune loads tidal turbine component for the Worlds first commercial scale tidal stream project - to be deployed in the Pentland Firth - at the Nigg Energy Park. One of my key projects for the past 4 years, delighted to see it at this stage.
NON-NUCLEAR COMPONENT STORES BUILDING 60 –
The function of the non-nuclear component stores was to hold the high explosive part of the bomb and its outer casing. The casing could probably be split into two units, the tail and forward part containing the high explosive and electronics. The bombs, minus their fissile components, were housed in three almost identical stores buildings 59-61, known as Storage Building Type 'D-D'. These are arranged in an arrowhead pattern, and are accessed from the internal loop road, and are all surrounded by 14ft 6in high earth traverses, revetted by a reinforced concrete retaining wall against the roadway.
The western store, building 59 was gutted by a fire during the 1980's and has subsequently been demolished. Its floor plan remains visible on the remaining concrete floor slab. The two remaining stores, buildings 60 and 61 are rectangular in plan, and are constructed from reinforced concrete columns and beams. Internally there are two rows of columns, 13in², which support the roof beams, 2ft by 9in, which carry the 9in thick reinforced concrete roof slab which is covered with bituminous felt. The rainwater gutters and down pipes are cast asbestos.
The wall sections are filled with 18in by 9in by 9in precast concrete blocks, internally the main storage area measures 190ft 2½in by 60ft. It is divided longitudinally into eleven 17ft by 3ft bays and cross ways into three bays the outer bays measure 17ft 6in and the central bay is 25ft wide. The maximum clear internal height was 12ft from the floor to the underside of the roof beams. The floor is surfaced with a hard gritless asphalt with the patent name 'Ironite'. The walls are painted pale green colour and the ceiling cream. in store building 61 the bay letters 0, N, M, and L are visible on the rear columns on the eastern side, suggesting the store was divided into 22 bays along the outer walls.
Abutting on to the front of the stores, and flanking the entrances, are plant and switch rooms, which originally contained heating and air conditioning plant to maintain a stable environment within the stores. A raised air extract duct is placed asymmetrically on the roofs of the stores. Entry into the stores is through a 10ft wide door opening with 12ft high doors. In the rear wall of the stores is a single door width, outward opening emergency exit. The first nuclear weapon the store was designed to hold was relatively large, a ''Blue Danube'' bomb measured 24ft in length and weighed 10,000lbs.
The problems of handling such large objects are reflected in the provision of substantial lifting gantries at the entrance to each store. Two variants are found, the simplest, exemplified by the middle store building 60 comprises a straight gantry. Over the roadway the gantry is supported by four 24in by 18in reinforced concrete columns, which support two 51in by 24in reinforced concrete beams. The upper beams of the gantry taper towards the entrance to the store where they are suppurted by two reinforced concrete columns. On the underside of the gantry is attached a 20in by 6½in rolled steel joist runway beam which runs to the entrance to the building. This was originally fitted with a 10 ton hoist. The gantry is covered by asbestos sheeting to provide a dry working area.
On the eastern and western stores the gantries were set at 30° to the front of the stores. In this variant an extra set of columns was placed at the 30° dogleg. Internally there is no evidence for a runway beam, so it presumed the bombs were lifted off a road transporter and loaded onto a bomb trolley for storage. It is not known how many bombs were kept in each store, or if the tail units were separated from the front part of the bomb for storage. Subsequent to the site being relinquished by the RAF a central corridor has been created in the stores by the insertion of breeze block walls. Doors in these walls give access to workshops along either side of the buildings. External windows have also been inserted in some of the bays.

Orford Ness is a cuspate foreland shingle spit on the Suffolk coast in Great Britain, linked to the mainland at Aldeburgh and stretching along the coast to Orford and down to North Wier Point, opposite Shingle Street. It is divided from the mainland by the River Alde, and was formed by longshore drift along the coast. The material of the spit comes from places further north, such as Dunwich. Near the middle point of its length, at the foreland point or 'Ness', lies the Orfordness Lighthouse.
Orford Ness is Europe's largest vegetated shingle spit. It is approximately 10 miles (16 km) long, and the site covers a total area of approximately 2,230 acres (900 ha). Forty percent of this (890 acres) is shingle, 25 percent (556 acres) tidal rivers, mud flats, sand flats, and lagoons, eighteen percent (400 acres) grassland, and fifteen percent (330 acres) salt marsh.
The spit formed almost entirely of flint deposited by waves through the process of long-shore drift. The main influence on its formation has been storm waves throwing shingle over the top of the beach crest, where it is protected from ordinary wave action. Over time, this process leads to the formation of stable ridges of fine particles, and swails of coarser shingle.
The size and shape of the spit fluctuates over time. Estimated growth rates range from 64m per year in 1962 to 1967, to 183m per year in 1804 to 1812. Between 1812 and 1821, the total length fluctuated by 1.8 miles (2.9 km). As a result of the dynamically changing nature of the spit, the true age of its formation is unknown. However, before about 1200, Orford is thought to have been a port facing the open sea.
The peninsula was formerly administered by the Ministry of Defence, which conducted secret military tests during both world wars and the Cold War.
The site was selected as the location for the Orfordness Beacon, one of the earliest experiments in long-range radio navigation. The Beacon was set up in 1929 and used in the pre-war era. In the 1930s Orford Ness was the site of the first purpose built experiments on the defence system that would later be known as radar. Having proved the technology on Orford Ness Robert Watson-Watt and his team moved to nearby Bawdsey Manor and developed the Chain Home radar system in time for its vital role in the Battle of Britain.
The Atomic Weapons Research Establishment had a base on the site, used for environmental testing. When a laboratory test is conducted to determine the functional performance of a component or system under conditions that simulate the real environment in which the component or system is expected to operate. Many of the buildings from this time remain clearly visible from the quay at Orford, including the distinctive "pagodas". Whilst it is maintained that no fissile material was tested on the site, the very high explosive initiator charge was present and the buildings were designed to absorb any accidental explosion, allowing gases and other material to vent and dissipate in a directed or contained manner. In the event of a larger accident, the roofs were designed to collapse onto the building, sealing it with a lid of concrete.
In the late 1960s an experimental Anglo-American military over-the-horizon radar known as Cobra Mist was built on the peninsula. It closed in 1973, and in the late 1970s and early 1980s the site and building were re-used for the Orfordness transmitting station. This powerful mediumwave radio station - originally owned and run by the Foreign Office, then the BBC and, after privatization in the 1990s, a series of private companies - was best known for transmitting the BBC World Service in English around the clock to continental Europe on 648 kHz from September 1982 until March 2011. The station has been disused since May 2012.
Orford Ness is now owned by the National Trust and is open to the public under the name "Orford Ness National Nature Reserve", though access is strictly controlled to protect the fragile habitats and due to a residual danger to the public from the site's former use by the military. Access is therefore only available by the National Trust ferry from Orford Quay on designated open days.
The next challenge is to replicate the equipment shown here on the rear deck such as the controller and meter housing. The right-hand box could house a knifeswitch or main fuse, I'm not sure.

Active components of the tireflies. The circular structure is a coil spring, which we are seeing end-on. When the structure is bumped, the spring bends until it hits one of the walls around it. When that happens, the circuit turns on and blinks for a little while. A neat trick is to instead force it to blink all day long by making the spring touch the walls all the time.

Project 'Sponsje'
This is a tool to hold electronic components on a PCB while upside-down. The tool is intended to assist while soldering parts in place. The pictures speak for them selfs I think
here's my old workspace.
sure, it was functional, but a little blah and lacking in the storage department.
so, i partnered with my contractor friend, and designed this custom desk/storage unit. it's still a work in progress, but i'm LOVING it so far.
i couldn't help but share a preview. this is the desk area.
The MSS first appeared in 1935 - a 500cc sports model designed to fit into the 'M' series comprising the 250 MOV and 350 MAC. As part of the series, it was an overhead-valve single with Velocette's own development of a high camshaft driven by intermediate gears, and short pushrods.
These were designed to give the low reciprocating masses of an overhead-cam model and similar reliability, and succeeded - giving the MSS a speed not too far short of the company's race-derived 'K' models.
Velocette MACs were among a number of machines produced for military use, but only one MSS was tested by the „,— army, and production ended for the duration. The 'M' series reappeared soon after the war, but as the factory were soon directing all their efforts into the 'revolutionary' pressed steel LE, all but the MAC were discontinued.
The MAC underwent a programme of development throughout the early 1950s. There were many detail changes to the engine, but the most important changes were to the chassis, with Velocette's own telescopic forks appearing in 1951 and a swinging-arm frame with Velocette's patented adjustable shock absorbers in 1953.
The year 1954 saw the relaunch of a model called the MSS, but in truth this was a very different proposition from pre-war days. The engine was of much shorter stroke, giving 'square' dimensions in its alloy barrel. The bottom end was similarly updated, and although the engine was softly tuned it was a modern design with considerable in-built strength. Despite the soft tune, the MSS was no slouch, being good for 80 mph or more, while the spring frame offered excellent handling.
It was no surprise, therefore, that it started to be tuned for higher performance. In 1955 a very rare scrambles version was offered, while 1956 launched the sports Venom model. This began a series in which higher and higher performance was achieved at the expense of the very flexibility and usability that had been the reason for introducing the pushrod models.
The underlying machine changed little, keeping outdated features such as the separate magneto long into the 1960s. It was such factors as the difficulty of obtaining supplies of components, coupled with the factory's ncreasing financial problems, that contributed to the end of the model in 1968. But its appeal lives on, with the qualities of the long-legged, economical single cylinder engine at the heart of the experience.

Aspirantex 2017
O Poder Naval do Brasil vai ao Mar!
_____________________________________________________________________________
Entre os dias 12 de janeiro a 02 de fevereiro, a Marinha do Brasil realiza a comissão Aspirantex 2017, um exercício naval destinado a aprimorar os conhecimentos e auxiliar nas escolhas profissionais de cerca de 200 aspirantes embarcados, entre homens e mulheres, egressos do 2º ano da Escola Naval.
Atuando na área marítima compreendida entre o Rio de Janeiro (RJ) e Mar Del Plata (Argentina), a comissão Aspirantex 2017 está nesse momento em visita aos portos de Mar Del Plata e Montevidéu (Uruguai).
Na sequência do exercício, serão visitados os portos brasileiros de Itajaí e São Francisco do Sul, ambos localizados no estado (província) de Santa Catarina, bem ao sul do Brasil.
Para a realização da operação, o comandante em chefe da esquadra, Vice-Almirante Celso Luiz Nazareth constituiu o Grupo Tarefa (GT) 701.1, designando o comandante da 1ª Divisão da Esquadra, Contra-Almirante Valter Citavicius Filho para liderar, coordenar e conduzir os exercícios que envolvem o emprego de diversos meios operativos da Força Naval Componente.
As metas do exercício envolvem o aprestamento dos meios da Esquadra e também contribuir para a escolha da opção de corpo e área de habilitação dos aspirantes do 2º ano da Escola Naval, sediada na cidade do Rio de Janeiro.
O GT 701.1 está composto, nessa primeira fase do exercício, pelo Navio Desembarque de Carros de Combate Almirante Sabóia (G-25), onde a reportagem de Tecnologia & Defesa encontra-se embarcada, Navio Doca Multipropósito Bahia (G-40), a Corveta Barroso (V-34), o Navio Tanque Almirante Gastão Motta (G-23) e as fragatas Type-22 Greenhalg (F-46) e Rademaker (F-49).
Na segunda fase, que começará dia 24 de janeiro, também irão se juntar ao GT 701.1, em apoio as operações, o submarino Tupi (S30), o navio-patrulha Benevente (P61) e unidades aéreas do Comando da Força Aeronaval e aeronaves da Força Aérea Brasileira.
Está prevista a participação do navio-patrulha-oceânico Amazonas (P-120), mas no dia 19 de janeiro esse meio foi destacado para auxiliar na recuperação dos destroços de um avião civil que caiu no litoral do Rio de Janeiro (região de Paraty, famoso balneário de luxo).
Entre os passageiros que faleceram na queda do avião está o ministro do Supremo Tribunal Federal, Teori Javascki, relator em uma das maiores investigações sobre corrupção já feitas no Brasil, a Operação Lava-Jato, que envolve diversos políticos, empresários e funcionários públicos da alta administração federal.
Aspirantes e as Operações Navais
Na desatracação do porto, no Rio de Janeiro, o GT 701.1 realizou a navegação em canal varrido (livre de minas) e enfrentou a oposição de submarino (S30) estrategicamente posicionado na saída para o mar aberto, sendo apoiados nessa tarefa por um helicóptero antissubmarino SH-16 Sea Hawk do Esquadrão HS-1 "Guerreiro" e aeronave de patrulha marítima e guerra ASW/ASUW Lockheed P-3AM da Força Aérea Brasileira.
Já em mar aberto, as operações aéreas dos helicópteros navais embarcados no NDM G-40 Bahia e nas fragatas Type-22 serviram para adestrar as tripulações dos navios dotados de convoo, nas fainas de lançamento e recolhimento desses meios.
Em paralelo a essas atividades, foram realizados treinamentos de CAV (controle de avarias), onde danos em combate e incêndios a bordo (simulados) foram combatidos por equipes compostas pelos aspirantes, orientados pelos tripulantes dos navios. Exercícios de Postos de Abandono , circulação interna a bordo e correta localização e operação das balsas salva vidas, dentre outros, demonstraram aos alunos da Escola Naval os perigos das atividades a bordo.
Em todos os dias de mar, durante a primeira fase, foram realizados inúmeros exercícios de Postos de Combate, visando verificar a prontidão operacional e aptidão das equipes de bordo, e tarefas como detecção de ruídos (A/S), Leap Frog/Light Line, manobras táticas e operações aéreas.
O tiro noturno contra granada iluminativa (GIL) e o tiro diurno contra alvo conhecido como "Killer Tomato" foi executado com o uso dos canhões automáticos de 20 mm, 40 mm e metralhadoras pesadas de 12,7 mm existentes a bordo dos navios. O NDCC G-25 Almirante Sabóia demonstrou excelente pontaria nas duas ocasiões, anotando diversos impactos certeiros nos alvos. Os outros navios do GT 701.1 não ficaram atrás, apresentando um desempenho satisfatório de tiro em ambas as ocasiões.
Os navios também se exercitaram no trânsito com oposição de superfície, a maior ameaça representada por mísseis superfície-superfície lançados pelo "inimigo". Do toque para Postos de Combate, passando pelo impacto do míssil (simulado) e o acionamento do CAV, é impressionante o profissionalismo e rapidez com que as equipes executam suas tarefas.
Esses eventos a bordo dos navios contam com a participação direta dos aspirantes, seja no preparo e planejamento, seja na execução como instruendos, ou indiretamente, como observadores, caso do tiro diurno e noturno com munição real.
Comandante de Operações Navais a bordo
O Comandante de Operações Navais da Marinha do Brasil, almirante-de-esquadra Sérgio Roberto Fernandes dos Santos, chegou a bordo do NDCC G25 Almirante Sabóia após transporte desde terra por um helicóptero UH-15/H225M da Aviação Naval (ver entrevista).
Na sequência das atividades, o CON realizou uma visita ao NDM G-40 Bahia, onde conversou com os aspirantes embarcados, mesma atividade realizada anteriormente no NDCC G-25 Almirante Sabóia, quando da sua chegada a bordo.
Light Line/ Transferência de Carga Leve
Uma das mais tradicionais fainas (tarefas) da vida no mar, o Light Line consiste na aproximação e lançamento de uma retinida (cabo leve), e na posterior troca deste por cabos cada vez mais pesados, capazes de suportar a Transferência de Carga Leve (TCL) entre os dois navios, que navegam lado a lado, mantendo velocidade e proa constantes.
Uma típica tarefa feita em equipe, é toda comandada através de toques de comando por apitos e emprego de sinaleiros, tudo isso enquanto os navios permanecem próximos.
A TCL dessa vez envolveu um marco histórico. Na faina realizada entre o NDCC G25 Almirante Sabóia e a fragata F-49 Rademaker, aconteceu a primeira travessia TCL realizada por uma mulher, a aspirante Amanda Passos. Primeiro, foi feito um teste com uma carga inerte equivalente a uma vez e meia o peso da aspirante, e após, a passagem real entre navios.
Na proa do NDCC G-25 e da F-49, tripulantes em linha ou dispostos em um "carrossel" realizaram a tração e movimentação dos cabos, a comando do Senhor Mestre do Navio, normalmente o militar de marinharia mais antigo. Comprovando a perícia das tripulações e a segurança dessa atividade, a aspirante Amanda Passos foi até a F-49 e voltou a bordo do G-25 incólume.
Mergulhadores de Combate!
O exercício denominado SURFEX 983 constou do emprego de um destacamento GRUMEC ao qual foi ordenado abordar um navio "suspeito", no caso o G-25, com o emprego da técnica Fast Rope, a partir de um helicóptero UH-15.
Em uma das portas da aeronave, um GRUMEC armado com fuzil sniper PGM Ultima Ratio, em calibre 7,62 mm, provê a segurança pelo ar do destacamento. Quando o UH-15 chega sobre o convoo, os GRUMEC descem pelo cabo e rapidamente assumem posições na proa do navio, avançando decididamente em direção ao passadiço. Do ar, e circulando sobre o navio, o UH-15 provê a cobertura aérea.
Após rápida subida pelas escadas externas, é dada a ordem para que TODOS no passadiço deitem-se no chão, para verificação (revista) e apreensão de armamento, caso seja encontrado. Na simulação, dois fuzis de assalto são encontrados com os "tripulantes", e o imediato do navio e seus oficiais subalternos são detidos para averiguação posterior, assim como os tripulantes que estavam armados. O material é confiscado e anexado nos autos de abordagem.
Os GRUMEC, tropa de elite da Marinha do Brasil, egressos do Batalhão Tonelero, apresentaram uma novidade nesse treinamento. Além do emprego de fuzis de assalto HK 416 em calibre 5,56 mm, foi possível observar os novos uniformes e equipamentos adotados (ainda em testes), como capacetes táticos, todos camuflados em vários tons de cânhamo e verde, bem diferente do material anteriormente empregado.
Após a finalização da apresentação, aconteceu uma palestra para os aspirantes a bordo, onde dúvidas sobre a carreira nas Forças Especiais da Marinha foram sanadas, e a vida desses militares foi apresentada pelo comandante do destacamento aos aspirantes. Por questões de segurança, nenhum dos GRUMEC pode ser identificado, e seus rostos nas fotos estão distorcidos intencionalmente.
GT 701.1 no Uruguai
Na chegada ao porto de Montevidéu, o NDCC G-25 Almirante Sabóia, líder do grupo de navios, saudou a terra com a tradicional salva de 21 tiros protocolares, prontamente respondida pelos uruguaios. Após a faina de atracação, que envolveu diversos rebocadores e um prático, foi realizada a bordo solenidade de recepção do Embaixador do Brasil no Uruguai, Sr. Fulano de Tal, e dos adidos militares, oficiais coronéis da Força Aérea Brasileira e Exército Brasileiro, além de autoridades uruguaias lideradas pelo Comandante-em-Chefe da Armada daquele País, almirante Fulano de Tal.
No dia 23 de janeiro, o GT.701.1 suspenderá de Montevidéu e Mar Del Plata, reunindo-se em alto mar para empreender a segunda parte da Aspirantex 2017, que envolverá treinamentos e exercícios como Transferência de Óleo no Mar (TOM) e reabastecimento de aeronave em voo (In Flight Refueling ou IFR) e Trânsito com Oposição de Submarinos, dentre outros. O destino final do GT 701.1 será a cidade do Rio de Janeiro/Base Naval da Ilha do Mocanguê.

A Beyer-Garratt is a type of steam locomotive that is articulated in three parts. Its boiler is mounted on the centre frame, and two steam engines are mounted on separate frames, one on each end of the boiler. Articulation permits larger locomotives to negotiate curves and lighter rails that might restrict large rigid-framed locomotives.
LANAI, Hawaii - Lt. Col. Julie Robinson, a dentist from the 176 Medical Group, works on a patient here June 5, 2013. Forty-five Alaska military personnel from Air and Army National Guard and active-duty Air Force traveled to set up and run medical clinics for medically-underserved Hawaiians on the islands of Lanai and Maui as part of an Innovative Readiness Training project June 4 to 12. The group joined about 500 other military personnel from multiple components of the Air Force, Army and Navy on four Hawaiian Islands at six sites as a joint training mission called TROPIC CARE 2013 – the largest IRT mission since the program began.

I love the way the colors came out on this one. It's sort of like a cross between terra cotta and maybe southwestern, but with a healthy dose of vintage antique paint layers. I have this one listed, but I might have to rescue it and make something for myself out of it.
