This is the “HobbyKing Quadcopter Control Board V2 (Atmega168PA)” [QUAD-CON16K] board. It’s bases on the KK control board. It contains three Japanese Murata piezo gyros for roll, pitch and yaw that are meant to be less sensitive to vibration than other gyros. The board has an Atmega168PA micro controller.
The board is meant to stabilise the quadcopter during flight. While there is documentation and I understand some of it I’m still struggling with this board. Adjusting the pots for roll, pitch and yaw is proving difficult but may not be the cause of my failing to fly.

Denver, CO -- The control tower is one of the last prominent features remaining from Stapleton International Airport. The tower now stands center of a residential and park redevelopment project. The last flight controlled by the tower was on February 25, 1995, when a Continental flight departed for London.

The control board is a go between. The radio receiver passes on the signal for the control board to interpret which passes on a signal to each of the electronic speed controllers which controls the speed of the motors.
If the control board detects the quadcopter tilting down it counters it by speeding up the lowered motor and slowing down the raised motor.
Controls on the Coral Monorail. Tempted to sit down and take it for a spin. Hey, they did give me a license signed by Mickey himself. :-D

Motion control head I designed around a pair of surplus precision worm gearboxes. The vacuum infused carbon fibre covers are largely superficial/protective, they were my first experiment in directly CNC machining a mould. I machined the aluminium parts on my CNC router and anodized them at home.
Because the head was constructed around existing gearboxes its a little larger and heavier than I would like, weighing around 5KG but supporting loads upwards of 10kg.
Easy Birding Peru offers tours from Cusco to the Manu National Park or to the Manu Biosphere, including our private Reserve Maquisapayoj, adjacent to the National Park.
- A trip to the untouched rainforest with plenty of undisturbed wildlife! EBP also offers various trekking tours, the Classic Inca Trail to Machu Picchu as well as several alternative treks.
For details see 'Cusco, Trekking and South of Peru'. The Manu National Park was created in 1973 and established a Biosphere reserve in 1977; in 1987 it was declared a World Heritage Site by UNESCO, due to the world´s highest biodiversity in Manu.
It is one of the largest and most important conservation units of the world, it protects an entire virgin watershed, covering altitudinal ranges from 200 m to 4100 m above sea level.
Amazon Travel Why go to Manu?
• Amazon Travel Ecotourism and Conservation
Manu is a very rich/ biodiverse but fragile ecosystem. Being home of several endangered species, e.g. Giant Otter, Harpy Eagle, Giant Anteater, Ocelot and Wooly Monkey, ecologically sustainable tourism in Manu is imperative and a low tourism flow is favourable.
Visitors should be informed about rainforest conservation and favorabletourism activities have to be controled ( e.g. don´t get too close to the animals). Ecotourism also is an important economic activity for the inhabitants of the rainforest that permits its use without distroying the rainforest resources.
That´s why it´s very important to involve local people in Manu tourism!

The alignment algorithm evidently knows to sacrifice those control points that it considers hopeless. This view indicates the discrepancy between the control points. Those that align well are shown as dots. Those that could not be aligned are connected with lines showing the residual distances.
This begs a question: why didn't I ditch the second frame? I tried. The result was even worse. However awkward its orientation seems to be, it helps to join the frames 1 and 3 where it matters most — at the skyline.
The distance view makes it easy to understand the orientation of the original frames. For example, it shows very clearly that point of view of the second frame (of which only a portion is visible) was a few steps away from the more-or-less shared point of view of the other frames.
This screenshot is best viewed in the original size because the dots and lines are one pixel wide. They vanish when the image is scaled down.

Timber is planed and shaped by machine but each item is fed by hand to enable quality control at the same time.
Working on attaching the control rod to the lower leg: tried a fixed joint, but the control rod always seemed to be in the wrong place, so I rigged up a flexible joint. There was a lot of strain for my wrist lifting the leg in certain positions, so I started playing around with this fore-arm brace, which seems to be helping (needs a little more hardware)
Not quite finished yet, will need some more programming and cable routing, but the proof of concept was successful.
Uses two modified Cyborg V1.1 flightsticks, plus three ministicks like in playstation controllers - one of them modified, too. The ministicks are attached to the flightsticks, on the back panel (visible in the upper shot) and where the trigger usually is - somewhat visible in the shot below - they are the orange parts.
The control centre is the Dalek's stronghold. It is scratchbuilt from card, although the 'authentic' Dalek bumps that make up its decor are humble lentils.

The voltmeter and ampmeter are clearly visible, with their respective scale.
Another one from the archive. This was a part of the upstairs control room. To my left, out of frame, was a massive wall unit that curved from one end to the other. Lighting was really low up here.
This is the button array on the right handlebar of my 1966 Sears Gold Seal Vespa. This is one of only a very few scooters sold by Sears, but NOT called Allstate. Just Sears.
But I don't know how all of these buttons work. It won't start, but it could be because one of these buttons is in the wrong position. The top button is a 3-position rocker, the left button is an off-on switch, but no clue as to which is which. The bottom button in for on, and out for off, as is the one on the extreme right. Any clues will be appreciated. This is a zippy little bike with 4 speeds and 125 cc's, and I really need to be riding it.
Trabajos realizados por Regeneracio Forestal S.L. en el sellado de vertedero y creación del Parque Forestal de Valdemingomez (Madrid). Colocación de redes orgánicas de Yute por personal de REFOR S.L. para la fijación de taludes y sobre las cuales se realizara la hidrosiembra, estas redes que tienen una permanencia sobre el terreno de aproximadamente dos años ayudaran a mantenerse el terreno reduciendo la erosión del mismo y favoreciendo la sujeción de la hidrosiembra hasta que las semillas germinen y la vegetación se fije al terreno.
REFOR S.L. coloca mantas, mayas y redes orgánicas y hidrosiembra en distintas obras para controlar la erosión del terreno, obras como la estabilización de taludes y terraplenes en distintos tramos de AVE Madrid – Valencia, Madrid – Alicante y Madrid – Barcelona, así como distintas obras en líneas convencionales de ferrocarril de ADIF en que Regeneració Forestal S.L. realizo la restauración medio ambiental de los mismos. El sellado y estabilización de vertedero como las tareas realizadas por REGENERACIO FORESTAL S.L. para la creación del Parque Forestal de Valdemingomez en el antiguo vertedero de Valdemingomez (Madrid); Fijación de Márgenes de ríos, barrancos, acequias, balsas y otras obras hidráulicas, estabilización desmontes y terraplenes en carreteras, autovías, caminos y pistas forestales; estabilización de taludes y restauración medioambiental de canteras; estabilización de taludes de pistas de aterrizaje como en el aeropuerto de Alicante …
Las áreas inclinadas son propensas a la erosión a medida que el agua frecuentemente se mueve pendiente abajo, lavando suelos y vegetación. Para controlar adecuadamente la erosión REFOR S.L. utiliza varias opciones de mantas, mayas o redes orgánicas que pueden ser compuestas por yute, paja, heno, coco, esparto, paja de arroz … dependiendo de las características del terreno donde se colocaran y de las exigencias técnicas de la obra. Estas redes o mantas ayudan a obstruir el flujo de agua y mejorar el ambiente del suelo. Todos estos componentes son materiales naturales y biodegradables, por lo que son ecológicos y se descomponen con el tiempo. Todos ellos, cubren laderas empinadas y pequeñas pero perturbadas. Son combinadas sus instalaciones con las hidrosiembras realizadas por los equipos de trabajo de Regeneracio Forestal S.L. con lo que se facilita la instalación rápida de la vegetación sobre el terreno con la fijación del mismo y la disminución de las escorrentías reduciendo la erosión.
MANTAS ORGANICAS
Las mantas orgánicas son elaboradas con distintos elementos orgánicos : paja, heno, yute, esparto, paja de arroz, coco … y se utilizan unas u otras dependiendo de las características del terreno en que se instalaran y de las exigencias técnicas de los proyectos.
Las mantas orgánicas son utilizadas para el control de la erosión, las partículas del suelo quedan retenidas entre los huecos de sus componentes, uniéndose a sus fibras durante su descomposición. Mejora la conservación del suelo y de las plantas, disminuyendo los daños por sequias o lluvias torrenciales.
Las funciones de las mantas orgánicas son:
-Aumentar la rugosidad del terreno.
-Disminuir la velocidad del flujo.
-Facilitar la infiltración del agua en el terreno con lo que se aprovechan mas las precipitaciones o aportaciones extras.
-Aminorar la escorrentía de agua sobre el terreno.
-Actúa como acolchado vegetal que se fija e incorpora al suelo aportando materia orgánica al suelo pasado un tiempo.
-Regula la temperatura del suelo reduciendo su exposición al frio y al calor, protegiendo las semillas procedentes de la hidrosiembra y facilitando la germinación.
-Disminuye la evaporación de agua retenida.
-Aumenta la actividad microbiana y de intercambio cationico.
-Favorece la implantación de la vegetación.
REDES O MAYAS ORGANICAS
Las redes o mayas orgánicas son elaboradas con distintos elementos orgánicos : paja, yute, coco … y se utilizan unas o otras dependiendo de las características del terreno en que se instalaran y de las exigencias técnicas de los proyectos.
Las funciones de las mayas o redes orgánicas son:
-Ayudan a sujetar o reforzar los suelos con problemas de erosión en suelos granulares de pendientes acusadas.
-Disminuyen la energía cinética producida por la partícula erosiva de las gotas de agua, copos de nieve o acción del viento.
-Aumentan la capacidad de campo o retención de agua por el suelo, disminuyendo la perdida de agua por escorrentía y evaporación.
-Regula la temperatura del suelo reduciendo su exposición al frio y el calor, protegiendo las semillas aportadas por la hidrosiembra y facilitando su germinación.
-Son materia orgánica que se incorpora al suelo.
-Facilita la implantación de la vegetación.
