Hello, my name is Krystian, and I will be completing my bachelor's degree in Information Technology Bcom next year. I have always been very passionate about technology and learning new programming languages. The first programming language I have learned is C in 2018 and since then I have learned a few other languages such as C++, Java and Python. After I complete my bachelor's degree, I would like to work as a data analyst at a large financial firm.

Overall, in this course, I have learned new writing techniques such as writing a reflection, writing about a device for search engine optimization and writing a repair guide for iFixit.

My e-portfolio shows what I have accomplished throughout this writing course. I now have extensive knowledge on how to write tutorials, guides and knowledge on search engine optimization. I’ve also learned how to reflect on what I’ve learned from this class and write about it.

I chose to write a guide for my Fast Fix Project on replacing a rear taillight bulb for a (2011 - 2018) Volkswagen Jetta. I chose to write this guide because driving with a burnt out taillight is a safety hazard for other drivers and it's important that a rear taillight bulb gets replaced quickly.

The device I chose for my device page project is the Hilti Diamond Grinder DG150 (2017). I chose this device because many workers in the construction trades need a device guide for when their tools break.

I started my Fast Fix project by first researching what type of repair would benefit the most amount of people. After doing some research, I found that most people had problems with the vehicle’s headlights and taillights. I then decided to do my Fast Fix project on replacing the rear taillight bulb for a 2011 – 2018 Volkswagen Jetta. I also chose two alternative topics in case my first topic doesn’t get approved by iFixit. The two alternative topics that I chose are: Lenovo ThinkPad T14 laptop screen replacement and Sony Vaio laptop screen replacement.

Next, I started doing research on how to perform the taillight bulb replacement. I found that many of the repair guides on the internet had photos with a dark background and with no markers. This made it very difficult to see precisely what repair was being completed and it took me much longer to complete this repair. I decided to take photo’s on a sunny day and include markers so when user’s view the image, they can precisely see which part is being repaired.

Once I had taken the pictures, the next step was to write a detailed description of each step of the repair process. In this step of the project I had learned that it’s important to use precise language, so a user will know exactly what action to take without needing to look at the photos. For example, if a part needed to be disassembled, I included the precise name of that part and also included the action a user would need to take to disassemble the part.

I started my project by finding three devices and choosing one for my device page project. The three devices I found were: Makita Chop Saw 2414NB (2010), Milwaukee Circular Saw 2530-20-G32A (2017) and Hilti Diamond Grinder DG 150 (2017).

I chose the Hilti Diamond Grinder as my device for this project because the manufacturer had listed detailed information on the device and provided user manuals. Next, I did extensive research on this device and found out it is an important tool used most often by concrete finishers on construction projects. Concrete finishers need to use this device to make a concrete surface smooth and aesthetically pleasing.

# data[].attributes.attachment_link.readable_text
The Hilti Diamond Grinder DG 150 was released in 2017 and discontinued shortly after the DGH 150 was released in 2021. The DG 150 is a special concrete grinder used in construction projects by concrete finishers for polishing hard concrete surfaces, removing paint and coatings. The Hilti Diamond Grinder is available in the North American, South American, European, Asian, African, and Australian markets. The retail price that was listed on the Hilti manufacturer's site in 2017 was CAD$4,000.00.

The DG 150 diamond grinder is more durable and has a larger motor compared to a traditional angle grinder which allows it to easily remove rough concrete surfaces. The Hilti diamond grinder has two speed settings: Setting I, has a maximum speed of 4700 RPM. This setting is mainly used for grinding soft materials such as paint coatings on cement rendering. Setting II, has a maximum speed of 6600 RPM and is used for grinding hard mineral materials such as concrete, screed or rock. It also has a built-in vacuum installed into the grinder so dust particles can travel away from the surface that is being polished.

The DG 150 device has no recorded failures or manufacturer recalls. Hilti provides a 20-year materials and workmanship warranty and 2-year wear and tear coverage. The component most prone to failure is the diamond cup wheel which will need to be replaced after extended use.

Identification
To identify the Hilti diamond grinder DG 150 (2017), it's important to look for a red colored device with a black handle and a white logo with Hilti DG 150 on the center of the device. The Hilti diamond grinder has a rectangular base with a side handle on the top used for controlling the device. On the rear of the device there is another handle used to hold the device, control its speed, and turn it on/off. The guard for the diamond cup wheel is located at the very front of the device and on the bottom of the guard there is a spindle and clamping flange which is used to hold the diamond cup wheel. This device has an LED indicator lamp located on both sides of the device by the main handle used to power the device. This special design feature makes it easy to distinguish from other diamond grinders. The dimensions of the device are: (L x W x H) 19.7 x 9.8 x 9.1 inches and the model number of this device is: 369388. The serial number can be found on the back of the device underneath the main handle.

The differences between the older model Hilti DG150 (2017) and the newer model Hilti DGH 150, is that the newer models are larger have a bulkier base with rough edges and a larger handlebar used for controlling the device. Also, the handle in the rear of the device has a connector for dust extraction.

I had no difficulty with planning and writing my repair guide.
However, the greatest challenge of this repair guide was taking good quality pictures. I had to choose a day where it was sunny, clear and had to choose good location with relatively few people around. My next challenge was to mount the camera in a position that showed a good view of the repair process. I did this by mounting the camera, taking a picture of the repair step being completed and checking if the picture was good enough to upload to the iFixit site. The whole process of taking photo’s took me about one and a half hours. Overall, I had learned from this experience that not everything goes as planned and that it takes time to carry out steps of a repair process and take good pictures.

Overall, the greatest challenge of this assignment was doing research on the device. At first, it was a little difficult finding information such as the retail price since the device was only manufactured from 2017 – 2020. However, I eventually found the retail price by contacting the Hilti corporation.
