Meeting finished at: 10.05pm Date of next meeting: 12.30pm on Wednesday 2nd November 2011

Minutes of the meeting of the Engineering Education Scheme 12.35pm on 2nd November 2011

Present: Farran Elvidge , Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Mrs. Charlesworth, Steve, Darren Apologies: 0

1. We discussed our ideas with Steve and Darren. We will be drawing these ideas on A4 paper, separately, instead of drawing it on the A3 paper. We would then further develop our own ideas. Action: FE, SA, AF, IP, VL

2. We asked questions from previous minutes such as the ‘twisty’ things, laser beam heat, dimensions of the shield and about the vacuum. Darren will give us a book about vacuum and will give us the dimensions of the shield and cut out hole next meeting. Action: DN

3. We went through the project brief and specification. We will be changing the format to. The format layout will be: - Brief - Introduction to the design - Problem - Talk about materials, what vacuum is, what material to use etc. - Specification We should also set it under aesthetics(which is functional) and environmental(the vacuum pressure is 1.0 × 10-6 millibar). Action: FE, SA, AF, IP, VL

4. To know more, we should go on the STFC website, then central laser facility to research about Astra Gemini. The Gemini target area is where the mirror would be. (Here’s the link: http://www.stfc.ac.uk/) Action: FE, SA, AF, IP, VL

5. We talked about the maintenance of the shield. We thought of using a plastic cover on the shield and to peel it off and replace it when it gets dirty.

Meeting finished at: 1.30pm Date of next meeting: 12.30pm on 9th November 2011 where we will be having the tour.

Minutes of the meeting of the Engineering Education Scheme 8.05pm on 4th November 2011


1. Started writing up the time plan, but we still need to fill in the blocks next meeting.


2. We talked about the project brief, we will need to finish it next meeting.


3. We also talked about our ideas. We will need to draw it on a separate piece of paper, neatly.

Farran has the original drawings of the ideas.

Action: FE, SA, AF, IP, VL Meeting finished at: 8.30pm Date of next meeting: 7.30pm on Tuesday 15th November 2011

http://www.stfc.ac.uk/


Present: Farran Elvidge , Sophie Atkins, Amber Farrow, Vanessa Leung Apologies: Isobel Powell

1. We discussed everyone’s design ideas and further developed it. We went through and discussed the design brief. As for the time plan, the weeks/blocks needs to be filled in. We still need to further develop our ideas and combine ideas together. Action: FE, SA, AF

2. As Issy was not in the meeting, please could you type up 2 paragraphs of what a laser is, what it does and what it will be used. The second paragraph about what a shield will do, what our shield will do and achieve. Action: IP

Meeting finished at: 8.15pm Date of next meeting: 12.00pm 9th November 2011


Present: Farran Elvidge , Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Mrs. Charlesworth, Steve, Darren Apologies: 0

1. We visited the lab today. The parabolic mirrors are focused by the beam. A slight adjustment will cause the beam to produce a cloud of rubbish and each time there has to be a clean, clear surfaced mirror for the beam to focus on. The shield will rarely move inside the vacuum chamber. It is adjusted outside before placing it in the chamber. So we have to rethink our designs and combine ideas together. We have to draw new ideas before next meeting. Action: FE, SA, AF, IP, VL

2. We also visited the target area. It would be better not to attach anything on the walls or on top while designing the shield as the pressure in vacuum chamber would cause changes to the walls so it would affect anything attached to walls. There is also a small lense which is similar to a CCTV on one corner of the chamber.

3. We got the book about vacuum and the dimensions of the mirror. It will be very useful when designing the shield. Bring the book to the next meeting while discussing our ideas. Action: FE, SA, AF, IP, VL

Meeting finished at: 2.15pm Date of next meeting: 7.30pm on 11th November 2011


Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Apologies: 0

1. We thought of new ideas as our old ideas were designed to move inside the vacuum chamber. We thought of using screws and the shield should be manually adjustable, such as using screws. The adjusters of the shield should be closest to the window as it will be easy to reach for it and not be in an awkward position. By next meeting, we should research 2 ways of manually adjustments and come up designs which can be adjusted outside the vacuum chamber. Action: FA, SA, AF, IP, VL




1. We corrected and finished the brief and specification. We still need to know the movements of the mirror and shield in the chamber once it’s closed. Will it be moving sideways, upwards or tilting?

2. We need to draw at least one design by tomorrow meeting. Think about adjustments of the shield outside the chamber and screws needed etc. Action: FE, SA, AF, IP, VL



Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Darren, Mrs Charlesworth Apologies: Steve

1. We have to design ideas and finish the agenda by next meeting so we can develop two ideas on the meeting. And on Wednesday’s meeting, we will finalize one idea. Action: FE, SA, AF, IP, VL

2. Amber discussed her idea, which includes a pointer on the mirror, it can prevent scratching between the shield and mirror. There should be 2-4 point of contact.

3. We asked about the dimensions of mirror and the degree that the mirror will tilt. Action: Darren

Meeting finished at: 1.15pm Date of next meeting: 7.30pm on Tuesday 16th November 2011

Minutes of the meeting of the Engineering Education Scheme 9.20pm on 22nd November 2011

Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung 1. We discussed our designed ideas and proposed 2 ideas by Farran and Sophie/Amber which

we thought were the best. We will choose a final idea at tomorrow’s meeting.

2. We also completed the agenda.

Meeting finished at: 9.40pm Date of next meeting: 12.30pm on 23rd November 2011

Minutes of the meeting of the Engineering Education Scheme 12.35pm on 23rd November 2011

Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Steve, Darren, Mrs Charlesworth

1. We discussed the developed ideas and decided to combine all three concepts if

necessary. We thought contact points may not be necessary as the shield will rest on the

mirror and may not scratch the main part of the mirror. We could use Sophie’s idea as a

prototype and Amber’s idea as a development idea. Also, if we have any questions, we

can Skype with Peta and ask her.

2. We should check the delivery dates for parts/materials required as they take about 6

weeks to be delivered. As for Farran’s design, could she research about threads.

Action: FE, AF, SA, IP, VL 3. As for the time plan, some dates should be changed as there are some errors and to

include some more tasks. Also, tasks should be broken down to: Start, Middle, End.

Action: FE, IP, SA, AF, VL

4. We should draw up 2D drawings/sketches by the meeting on Wednesday with top, side

and front view.

Action: FE, AF, SA, IP, VL

5. Steve will send the dimensions of mirror, drawing of the holder and check debris.

Action: Steve

Meeting finished at: 1.15pm Date of next meeting: TBC


Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Vanessa Leung Apologies: Isobel Powell

1. Farran brought a simple model of the design. We still have to think about the shield tilting as

the current model can only go forward/backwards and up/down. We looked at Amber’s

gear, which can go 360 degrees and can be useful. We will draw the dimensional drawings of

the ideas on A3 paper next meeting (Tuesday).

Action: FE, AF, SA, IP, VL Meeting finished at: 8.10pm Date of next meeting: Tuesday 29th November 2011


Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Mrs Charlesworth, Steve, Darren Apologies: 0

1. Issy: Ondrives website would be a better website to find gears.

2. We discussed Sophie and Amber’s ideas. We would need to draw an orthographic drawing

of the design and produce a cutting list as soon possible before the workshop. We also need

to write a flowchart.

Action: SA, AF, FE, IP, VL

3. We need to think of a way to measure the degree when the shield tilts, and know the exact

dimensions of the gear. The ball and socket idea is an alternative idea.

Action: SA, AF, FE, IP, VL

4. We need to discuss workshop details on 8.30am on Saturday with Mrs Charlesworth.

Meeting finished at: 1.15pm Date of next meeting: 7.30pm Friday 2nd December 2011

Minutes of the meeting of the Engineering Education Scheme 7.40pm on 2nd December 2011

Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung Apologies: 0

1. We decided not to use the gear as it takes too long to be delivered. It takes approximately 3

months to be delivered and it is too complicated.

2. We designed a simple mechanism to tilt the shield and measure it at the same time. It is

similar to a ball and socket, which can be tightened and adjusted easily. There are 2 rings

which are connected to the stick and can be adjusted when loosened. We have drawn out

the basic idea of the design, with basic dimensions. We still need to produce a cutting list

and flowchart.

Action: SA, AF, IP, FE, VL

3. We are not sure of the angle of the shield and need to ask Peta about it.

Action: VL

4. Issy would be scanning our initial ideas which will be drawn with pen over it and to be put in

the file.

Action: IP


Minutes of the meeting of the Engineering Education Scheme 12.45pm on 11th January 2012

Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Steve, Darren, Mrs Charlesworth Apologies: 0

1. Farran and Sophie to transfer CAD drawings.

mechanically and inside the chamber on 1st Feb and 6th Feb in RAF.

Action: SA, AF

3. Amber to send the specification to Farran to be included in the report.

Action: AF

4. We must collect all information together and email everything to Steve, including the

logbook.

Action: FE, IP, AF, SA, VL

5. The Design Process in the report should include analysed ideas which include time,

complexity, time and why we did it. Initial ideas should be included in the report as well. In

the report, we have to include ‘How to test it’ where we suggest ideas such as alignment

lasers. We should start thinking about the finance, such as the hours of the technician and

materials etc.

6. On 21st March, we should practice presenting our presentation which should be 15 minutes

long. We could include videos.




1. Amber to send specification to Farran by Monday and Issy to send the appendix to Amber.

Action: AF, IP

2. On Monday meeting, we should start writing the design evolution (processes) which can be

written as a score chart. We should also alter anything on the time plan if necessary. We

should discuss about how to test ideas. The minutes should also be included in the appendix.

There will be memory sticks to collect all information.

Action: AF, IP, FE, SA, VL

3. Steve to send costings to Amber.

Action: Steve

4. We should include a working instruction for the design. For example how to use and do it. It

can be made into a video which can be then embedded into the presentation.

5. On the 21st of March, we will be practicing our presentation as we will be working on our

presentation for the last 3 weeks of the term. We will hopefully finish everything by half

term in February (in 3 weeks), it includes the design, testing and the report as this will leave

us time to change anything if necessary.

6. The schedule (deadlines) which will be sent by Steve should be included in the presentation.

Action: Steve

Meeting finished at: 1.00pm Date of next meeting: Monday 23rd January 2012



1. We have to make sure there is a school logo and engineering logo on each slide of the

presentation. We may have to think of a project name and find pictures to include in the

report.

2. Amber to type out costings on a spreadsheet and email it to Issy.

Action: AF

3. We have to finish the final design before half term (in 2 weeks). And when the design is

completed, Steve will come up with the pieces.

Action: SA, Steve

4. As for the Design Evolution, we have to evaluate each step such as the idea’s function,

achievement, ease of use etc. and give a score. We must reference each design. Issy will

organize all the ideas/designs.

Action: AF, SA, FE, IP, VL

5. When all the parts of the design are assembled, we will then have to making the working

instruction.

6. We should send the report and time plan to Mrs Charlesworth and Steve to see if there are

any mistakes and alterations needed to make.

Action: FE, AF, SA, IP, VL Meeting finished at: 1pm Date of next meeting: 9pm Friday 27th January 2012

and costings to both Mrs Charlesworth and Steve.

Action: FE, VL, SA, AF

3. As for the meeting of Friday, remember to bring USB stick to do the presentation. We will

write up a method statement for testing, which includes how to achieve it and a plan of

what to do. The testing will be part of the evaluation. We also have to discuss what to have

in the display, which includes props. We will also be discussing the evaluation analyses and

progression(where to go next).

4. Steve to send in the logo.

Action: Steve

Minutes of the meeting of the Engineering Education Scheme 9.05pm on 3rd February 2012

Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung Apologies: 0

1. We discussed the testing of the design. Using a laser to show the holes are aligned and using

different distances to test it. There will be a screw at the back to hold everything together.

We will soon make a dummies video guide.

2. Sophie’s design is deleted. We also decided that in the presentation, Farran would read out

the research part as she quite a lot of work in it and Issy would read out the introduction

part.

Meeting finished at: 9.20pm Date of next meeting: Wednesday 8th February 2012

Minutes of the meeting of the Engineering Education Scheme 12.40pm on 29th February 2012


1. Farran to email the report to Sophie and Amber for the design and we have to add

orthographic drawings in the report as well. We may have to print 12 copies of the report

when it is completed.

Action: FE

2. At the moment, we are still meeting the evaluation, design, appendixes and bibliography in

the report. We also have to add modification (detailed) in a separate section. Also, when

the criteria of the design is completed, it should be sent to everyone else. We should include

problems such as finishing before the end of term rather than the final date and delay dates

for the design.


3. For next week, Issy should complete a risk assessment for the test and we should pass the

reports around and comment on it, and start working on the presentation.



Minutes of the meeting of the Engineering Education Scheme 12.44pm on 7th March 2012

Present: Farran Elvidge, Sophie Atkins, Amber Farrow, Isobel Powell, Vanessa Leung, Darren, Mrs Charlesworth, Jonathan (adviser of the product) Apologies: Steve

1. We should include what the mirror does and the reason for it in the report/presentation.

Also, the laser scientists control the laser and install it.

2. By next Wednesday, the report should be completed (except testing and evaluation). There

are still some sentences that need rephrasing and words that need to be defined. We also

need to include problems that might come with the design, such as the design has limited

movement and the shield may crash into the mirror. As for modification of the design, we

can include Amber’s previous design with gears and development + improvement of

Sophie’s design.


3. We will be testing in the optics room next Thursday (15th March) at 12pm.

4. Steve to re-send drawings to Sophie and we still need brackets from Steve and Darren.

1. We did the presentation and it was around 15 minutes and received some

feedback.

- We need to speak slower

- We only need notes and not read it out from the paper

- Make sure what we are saying matches the slide from the powerpoint

- We should give more examples, especially for initial and final design

- We will need to add more about the design itself and less on research,

emphasizing how important the design was. Also, we need to include a slide

for manufacturing along with the design.

- We have to explain more clearly about the aim of our design and explain

what RAL is.

- We were not clear enough about the design and the testing. Also, we will

need to describe what our test was and how to test it etc.

- Abbreviate PEEK and find out what its structure is.

- We will need to add another slide after conclusion for acknowledgments and

give an ending.

- We need include project planning in the time plan.

- We may have to change/delete some slides to make sure the presentation fits

in 15 minutes.

- All props out for the presentation.


2. We have decided to put the slide ‘STFC’ and ‘Astra Gemini’ together, take away

the research slide about ‘high vacuum’ and ‘gas flow in vacuum’. ‘Initial ideas’

should be more detailed and should be placed before ‘materials under vacuum’.

We have to add manufacturing with the final design slide.
