Cyclical Electromechanical Programmer School year 2017/18

One more school year comes to its end. Despite the fatigue and stress of these last weeks, we must congratulate ourselves once again for the effort made to get the end and reach our goals

In this second year of giving our subject in English, it has been time to experiment new methodologies and processes, trying to overcome some problems detected last year. For example, leaving the workshop for the last term prevented us from developing those more practical contents with the necessary calm and attention. The same happened with the contents of electricity.

So, in order to try to solve this, we started working on project from the first term, every Friday. However, finally we have had the same problem. Many of the groups have finished their projects late, fast and running. Sometimes the perspective that there is a lot of time left for the end lead students to invest too much time in the accessory (such as sanding and painting) and little for the essentials (mounting the mechanisms and the electrical circuit). This is known as "Procrastination" and there are interesting theories about it. I'm afraid I'll have to tighten up on the deadlines next year.

Nevertheless, all the groups finished their projects, so we can feel satisfied with the result.

This year, and following the idea of "Continous improvement", we have introduced new steps in the process of designing the project:

  • Analysis of similar cases: studying projects of other years (online and in the workshop)
  • Ladder of feedback activity: expose and discuss initial designs with other groups to clarify and improve them
  • Draw plans of the project using a software for Technical Drawing: Cadstd
  • Self and Peer assessment: intermediate and at the end of the school year.
  • Intermediate assessment for the report: before building there has been a break to check our designs and improve them.
  • Rotating roles in the groups throughout the school year.
  • Final exhibition of projects, explaining how they fulfill (or not) the compulsory and optional conditions. First we have exposed in class, and later to the groups of 2nd of ESO trying to prevent our schoolmates from making the same mistakes we made.


All of them have been very satisfactory but it is true that they consume time, which in this case has had to be detrimental to other parts of the subject. This year we haven't had time to study the unit of hardware and operating systems. Instead, we have gone much deeper into the contents of electricity.

Here you are the description of the main elements of projects of this year:

- Transmision of motion

Most of the groups used a simple worm gear system to reduce the speed of the electric motor














There were groups that added an extra reduction system to their projects to get more control to the final result. They have used pulleys with belt and gears with chain.







- Moveable element and switches


Most of the groups chose cans as moveable elements, and metal sheets as switches




But there are groups this year that chose disks as moveable element. It was a bit more difficult to adjust the wires to keep in contact with the disk.



- Receivers

This is the space for creativity!

- Cinema:


- Car race:



- Don Quixote and windmills



- Stars in the sky



-Clock towers and cars








- A house: 


- Or the habitual traffic light





My congratulations to everybody. I am sure it has been a great experience of working together, in a common project and with a product to show and be proud of it.



Finally, here it is the video with some of the projects working. Despite all the problems it is necessary to face, everything is compensated by the feeling of seeing the project working

Julie Newmar: Inventor of the pantys

Biography


Julia Chalene Newmeyer was born in Los Angeles, the 16th of August 1933. She is now 84 years old.

From an early age, she studied piano, classical ballet and dance. She graduated from high school when she was 15. She became prima ballerina for the Los Angeles opera.

She entered the university of UCLA scoring a 99 in the entrance exam. There, she intended to study piano, French and philosophy. But she stayed there for only six weeks because she switched to Universal Studios to be a choreographer, teacher, and dance double.  
Julie Newmar acted in Broadway musicals, which made her famous. That allowed her to obtain the role of "Cat Woman" in Batman.

Invention


In the 70s Newmar invented the pantys and in the 80s she started selling them.


She needed tights that looked good on her, that didn't flatten her bottom. Her solution to that was inventing some tights herself. She cut the panties diagonally to the fabric thread and turned the central seam into elastic.

PASTY O'CONNEL SHERMAN     

BIOGRAPHY

Resultado de imagen de patsy o'connell shermanPasty O'Connell Sherman was born on 15th September 1930 in Minneapolis. She studied in Gustavus Adolphus College. According to the results of her tests, people thought that she must be a housewife. She asked to do the tests for boys and that results showed that she was really good in science. 

Later she became a chemist and joined to a company called 3M. In 1952 she co-invented Scothgard with Samuel Smith. They received their first prize together in 1972. Along her life she received seventeen prizes, thirteen of them shared with Samuel. Pasty worked for forty years in 3M and she was a managerial in the company. 

In 1992 she stopped working. Pasty married and had two daughters who loves the science too. One of them is a chemist and the other is a biologist. Pasty died on 11th February 2008 in Minnesota.

INVENTION

Resultado de imagen de scotchgardPasty was in a proyect to discover a resistant rubber material to the deterioration of plane fuel;but instead of this she discovered a new fluorochemical compounds.

In 1956 3M company took to the market "scotchgard protect".It's a polymer that repels spots and water in waves. This product makes a invisible obstacle which protects it from possible spots, it keeps the same waves's properties,and it's ordoress and particular because is the only one that resists oil spots. When some liquid falls down but there is scotchgard you can clean it with a towel and without leaving remains.

Resultado de imagen de dishwasher of cochraneJoe Houghton designed a dishwasher that worked due to the movement of a handle.
In 1860 L.A. improved the device, these were particularly effective.
Josephine designed the first model of her dishwasher on the hut of her home. George butters,
a mechanic, helped her with the construction.

To make it, she measured plates and cups, then, she designed its compartments and, 
finally, she introduced an engine which moved the mechanism. This dishwasher was the first one 
that use pressure water.

She showed her invention at "The Universal Exhibition of Chicago" in 1893, and it won the price of 
"The best mechanical construction, durable and adapted to the pace of work"
Her factory business began in 1897.
It was an innovative invention that had many reputation and it influenced a lot in that time

Daughter of Seth and Elisabeth Babbit who were members of Shakers comunity.

She was a weaver and member of the community .

She invented the spinning wheel , false teeth and the most importantly the circular saw. 

One day while she was weaving she saw two man cutting wood and she realized that half of his moves were wasted.


three years later in 1813 she made a circular saw this saw was connected to a water powered machine to reduce the effort of cutting wood.

But she didn't legalize a man did it so there are assumptions that she didn't make it .

Thanks to the invention of the circular saw made the trade much easier.
