I2P: Pecha Kucha Development

For the interview project that I had to conduct, I decided to choose a topic about the food at HKIS and the pricing. My partners for this project were Sheel, Carlos, and Olivia.

Before we even started this project, we decided to brainstorm some ideas for what bothered us. Even though I came up with many ideas and wrote them all down on sticky notes, something I was really annoyed with at this school was the cafeteria. Because I kinda had a passion for food and the food at this school, I decided to work in the group that would be conducting interviews with people concerning the school food here at HKIS.

One of the first tasks that the four of us had to complete was to create a questionnaire with the questions that we wanted to ask people so we would be prepared when we actually went to interview the person. Ms. Mok advised us to try and have open ended questions that would require an abstract answer, as opposed to a closed question that had a ‘yes or no’ answer. This way, we could have more specific opinions rather than just yes or no.

Even though this was the first and probably one of the easiest tasks, our group still struggled with coming up with good questions. We also did have some disputes within the group, which meant there was some misunderstanding as to what questions were good and which ones weren’t. Also, at one point of our development, our group values quantity over quality, so there were a lot of questions in our questionnaire; but they were all yes or no questions.

After Ms. Mok’s opinion and further revision, we finally got a decent number of questions that would help us to have more useful results. Instead of having yes or no answers, these questions asked for answers that students had to come up with themselves.

In order for us to try and interview multiple people at the same time, we decided to pour all of our questions into one common google doc. This way, we can all use our phones and laptops to go out and ask people questions separately. This way, we could have more results that would give us a more clear and detailed end result and consensus.

We also ended up recording the results on the same document, so we could easily access out results and the questions at the same time on the same document.


We took full advantage of being able to interview many people at the same time, so we decided to split into pairs of two so that we can interview more people.





When we interviewed people, we made sure that we took good detailed notes and quotes from their answers. When I was making my Pecha Kucha, I realized how important it really was to keep quotes since they are more reliable and are the exact answers that were given by people.


When I was making my Pecha Kucha, I also faced many difficulties. One difficulty that I had to overcome was to be able to include all my content on my slide that was only 20 seconds long. This proved to be hard for me because I usually like to add extra details and descriptions in order to make it more clear. With a timed presentations for only 20 seconds, I was not able to add these details because I wouldn’t have enough time to address some of the real issues. I also had to find a way to write a script that was easily memorizable as well as practicing many times so that it was consistently at the same pace so that the timing would always be 20 seconds every time I practiced.

After reviewing my presentation many times, I realized that I had too many slides concerning what the likes and the dislikes were towards the cafeteria food here. I spent most of my 20 slides on addressing what the problem was, and not how to solve them. In the end, I only had one to two slides that I could use in order to tell my audience what my proposal was to solve the problem.

I found out what I needed to work on in my presentation, so I decided to solve the problem. I decided to summarize my points more concisely so I could combine two or more slides into one. This way, I could have more slides in order to tell the audience what I plan on doing in order to solve the problem with the food at HKIS.

IMI Reflection SUMMATIVE Post

This is the sequel part to the formative post.


For the main screwdrivers, we had 2 sizes and 3 colors. We had red, blue, and green screwdrivers. We also had two sizes; one size with a hole diameter of 5mm and the other at 9mm. Here are the pictures of the different colored and sized screwdrivers:

Screen Shot 2015-12-08 at 10.06.38 AM

After measuring the dimensions, we decided that we could print the same design for the 9mm screwdrivers and the same design for the 5mm screwdrivers. The same size would have the same design, but they would be colored according to the color of the screwdriver.

Second Draft

(This post skips directly to the second draft, as the first post already covers the first draft) After we realised that the holes for the screwdrivers were too close together, we proceeded to move the holes farther apart so that all the screwdrivers could fit inside. We designed them again, but ended up with many failures before we got the ‘perfect’ model. One of them had a big triangular hole in it, the other one just didn’t  print holes for the screwdrivers at all. They are shown below. Screen Shot 2015-12-10 at 9.51.20 AM

After revisiting the design many more times, we finally got the working model and printed many copies of it in different colors for different screwdrivers (pictured below). Screen Shot 2015-12-10 at 9.56.13 AM


For the scissors, we used sketchup (again) and designed two poles attached to the backboard which will have each handle of the scissor go in one pole. Here is what it looked like on the computer:

First Draft

For this project, we only had one draft since we design and measurements went along together. We printed it out using the 3D printer, which took 5 hours; 3 hours longer than the screwdrivers. This is what it looked like when it was done:

Screen Shot 2015-12-10 at 10.01.23 AM

As you may see above, we had to use the hot glue gun to re-glue the poles to the base board.

. Screen Shot 2015-12-10 at 10.03.44 AM

This is because the bond between the base board and the poles wasn’t strong enough, so they broke off. We couldn’t really do much with the design either, because if we made the poles thicker, the scissors wouldn’t be able to fit on the holder.

In the end, this scissors holder works and this is what it looks like with the scissors on it.

Mistakes Made

When we printed the scissors, we did it afterschool. When it came to the time to leave, we decided to turn the printer off whilst it was printing, causing us to lose one and a half hours worth of printing. At the end, we were only left with a unfinished portion of the base board.

Another holder we designed was the matrix screwdriver holder. The matrix screwdrivers are screwdrivers designed to be used for the matrix robotics system. Here are what the screwdrivers look like:

We printed a similar holder as the normal screwdriver holder, but we made the holes wider in diameter to be able to take in the blue area since that would be where we would hang it by:

Screen Shot 2015-12-14 at 11.01.48 AM

Designing the matrix screwdriver on sketchup was probably one of the hardest things we had to design in this project. We had multiple revisions:

Screen Shot 2015-12-14 at 11.03.42 AM

Screen Shot 2015-12-14 at 11.03.15 AM

In the end, the matrix screwdriver didn’t turn out well when we tried to print it, so we are currently revising the design so that it will print out normally on the printer.

Zipties and Stationery Holder

The last thing we decided to design was a holder for stationery (pens, markers, pencils etc…) and zipties (cable ties).

We first designed it out on the whiteboard, having the same design for both the stationery and zipties but just with different dimensions:


We basically decided to make it a box that is split into three different compartments:

Screen Shot 2015-12-14 at 11.11.08 AM

The design looked good on sketchup, so we proceeded to print it out.

We were obviously wrong, because this is what we got when we printed the zipties:

It was weirdly printed, with one compartment a triangle instead of a rectangle and another compartment that was completely gone. We knew that something was wrong with the design, so we started to redesigned it. We are currently redesigning it, so it isn’t finished yet.

Moving on to the stationery holder:

The stationery holder also looked good on sketchup, so we proceeded to print it. Screen Shot 2015-12-14 at 11.11.20 AM

This was expected to be finished within 20 hours spread over a 2-3 day time period, since we had to stop the printer afterschool as 3D printer fires may start.

At lunch time on the second day, I went in to check in on the progress that it had made since PCG. I discovered that someone either pulled the plug out of the socket, or turned the machine off. When you turn off the MakerBot during printing, you will not be able to resume, meaning that Naomi and I lost nearly 16 hours of work due to one person’s mistake. We never found out who did it. We are currently printing another one to replace it.



Overall, this project was a great success even though we didn’t finish our project wasn’t completed (printing, all designing was done). I am proud since students in the next semester and after that will be using the organizers that Naomi and I designed for a very long time.

As for the printing, Naomi and I will take turns coming Wednesdays after school during ‘The Mess’ in semester 2 to finish the printing. Mr. Lea will get the aluminium parts to fit to the organisers so they can hang on the wall.

I believe that by February, we will be done with printing and the organisers will be hanging on the wall for usage.

IMI Slack Wall Organisation Formative Post

Its My Idea: Re-organisation of the slack wall in room 315B


For my project, I decided to redesign the organisational structure in room 315B.

This is the current slack wall that is used to store tools:

We saw that this type of organisation wasn’t ideal, so Naomi and I decided to redesign the boxes and bars that were used to store the items.


First, we had to make our plan.

We drew out our possible designs on a sheet of blank paper, brainstorming ideas that we could use in our final designs.

Then, we used a tape measure to precisely measure the measurements of the tools so that we could design our pieces to fit the tools.

First, we decided to measure screwdrivers.

Screen Shot 2015-11-30 at 9.44.17 AM




Then, we used our design from the paper and the measurements we took to create a model on SketchUp.

SketchUp is an app that you can use to make 3D models. It is a 3D modelling software.

After putting the model that we drew onto the laptop, this is what it looked like:

We then continued to export this into an .x3g file, the file format that the MakerBot could read so it could print.

This is a video of the MakerBot printing the first draft of our screwdriver holder.


About half way through the printing of the first draft, I realised that we had some design issues.

We measured the diameters of the holes, but we didn’t consider the fact that the spacing of the holes would be an issue. We wanted the screwdrivers to hang by their handles like this:

Screen Shot 2015-12-01 at 11.46.04 AM

Our issue was that the distance between the holes (depicted by the green arrow above) was too small, and that the screwdrivers couldn’t fit since the handles would clash against each other, even though the blades of the screwdriver could fit.


We learnt from our mistakes, and spaced the holes 4cm apart, more than enough space for the screwdrivers to fit. This is our second draft:



Afterwards, we again exported it to an .x3g file, placed it on the SD card, and printed it out.


This is the part one of the IMI post series. The second will be posted later as a summative.
