How Video Games Changed My Life

No one ever starts out super confident right?

Surely everyone has gone through a point in their life where they hate themselves, and feel lost about who they really are?

Well I don’t know the answer to that, but I do know that I used to be extremely insecure. I barely talked, and I could not connect with others. I was super weird and different from everyone else, and that really took a toll on my self-esteem.

But you know what helped? Online multiplayer video games.

Of course it wasn’t the only thing that made me more confident. But I don’t know, I distinctly remember playing Overwatch for the first time with other people. I was pretty nervous, but I soon warmed up to it and it became easier to talk to them. Suddenly, communicating in real life was easier as well.

I play Rainbow Six Siege now, which is a lot more intensive and teamwork is essential. I find that it actually helps me think more critically. If I want to do well, I have to plan out what to do before the action phase begins. No…before that, while I’m selecting my character. If my teammate is being difficult I have to figure out how to resolve the situation. If my original plan doesn’t work, I often need to come up with a new strategy on the spot. I learned how to communicate with strangers, as well as how to stay calm under pressure.

Video games used to get a bad rep. (Well…they still kinda do.) Of course it’s bad to waste your life away playing video games all day if its not your job. But I think it’s important to consider the impact video games can have. Such as improving one’s social skills and learning how to work better as a team.

Drone Modifications – Multi-Mode Hybrid Unmanned Delivery System (MMHUDS)

The 3DR drone was used because it is an extremely durable drone, therefore it can handle being roughed around and crashing several times. It can also be programmed using ArduPilot open source software (e.g. Mission Planner).

A downside to the durability of the drone, is that it is quite heavy. When flying the stock drone around, there was some lag which made it tricky to control and increased the learning curve.

To solve this, we took the drone apart and made some modifications.

 

 

The drone body needed weight reductions. A 1 inch hole saw was used to drill holes into the side of the body. These holes were carefully planned out to keep them relatively equally spaced. This got rid of excess material without compromising the structural integrity of the drone.

The plastic bottom of the drone was deemed unnecessary as well. This was cut out using a handsaw at first, which was quite difficult so we ended up using a Dremel tool instead.

Later on, we would end up attaching a metal plate to the bottom for increased structural integrity.

Groundbreaking Delivery – Multi-Mode Hybrid Unmanned Delivery System (MMHUDS)

Originally I was writing a post on drone modifications, but then I realized I was getting ahead of myself. I didn’t even explain the concept of our project. How inconsiderate of me!

Well I’ve already shown our starting points in my last post. I do wish I started these posts while I was working on this project, but I’ll summarize the best I can.

Millions of packages are delivered every day. Now that online shopping has become commonplace, faster and faster delivery is becoming a priority. Technologies such as drone delivery are being tested and could possibly be implemented into modern society. These strategies could even be better than current technologies. Consider delivery trucks having to make every single delivery by driving all the way to each destination, no matter how big or small the package is. Delivery trucks are incredibly bulky and slow, so each delivery route burns up a lot of gas and adds to the environmental damage to the Earth.

My group’s idea was similar to the blimp delivery concept done by Amazon. However, blimps are known to be quite slow, so we wanted to create a faster delivery system for smaller packages.

The issue with drone delivery is there has to be a compromise between weight and battery life. To resolve this, we came up with a drone and plane combo.

The plane acts as a “mothership” which the drone and glider will start from. Fixed-wing planes are flat on top which gives space for the drone to stay on. They are also good for flying longer distances. The plane helps with delivery by carrying the drone most of the distance to the destination. While the drone makes the delivery, it will circle around the location and wait for the drone.

The drone acts as a two-way delivery system. It can deploy from the plane with the package, fly the rest of the way to the delivery location, make the delivery, then fly back to the plane and reattach itself to the top using a simple mechanism.

The glider acts as a one-way delivery system. It will be made out of very light materials, and will be used to delivery very light packages. Since it’s “one-way” it must be made from cheap material, and must be easily manufactured. The plan is that the customer can either keep/dispose of the glider, or send it back for a minor discount.

This delivery system could be deployed straight from a warehouse, or combined with trucks which will work as base stations. This method is faster and more efficient than having large trucks delivering small packages, especially in rural areas.

Why do I feel so useless? – Post-Grad Depression

Upcoming content will be 2 posts in a row! Stay tuned…


 

I’ve been feeling weird these past few weeks.

Summertime always makes it hard to sleep for me, so it’s mostly likely that. But it’s also a minor case of post-grad depression.

It was rather freeing for me once I realized that I have no obligation to become an engineer. Sure I am extremely interested in engineering, and I would love to get a job related to my field. But if I can’t, then that’s ok. I took some classes in economics and found them pretty interesting, so I could definitely consider a job in that topic as well.

Also, I’m not useless. I live with my parents and I am helping them with cooking and housework. My life may not be not be the best, but with my dad being ill…I don’t care. I live a minimal life with a roof over my head and good food to eat. That’s enough for me.

While I’m applying for jobs, I will continue to improve myself by: learning different programming languages, working out, taking online classes, and creating things which I will post on this website.

Project Foundation – Multi-Mode Hybrid Unmanned Delivery System (MMHUDS)

Whew! I’m compiling a bunch of stuff about my project to post all at once and it is taking more effort than I thought. But I don’t mind because I want to include all the details.

Any project is made up of the basics or the foundation which one builds off from.

For my design group, our starting blocks consisted of a fixed wing plane as the mothership, and a quadcopter drone as the two-way delivery system.

The Piper plane is relatively easy to setup. The servos and the Electronic Speed Controller (ESC) are all connected to the AR610 receiver. This receiver came with the DXe transmitter and they arrived already paired, which made setup very simple, and the plane could immediately be flown once everything was connected.

The DXe transmitter can be programmed with the DXe Spektrum programmer. This program can be download on PC, or on mobile with the Spektrum DXe Programmer app.

As for the drone, the 3DR drone was part of a whole kit with the controller, extra batteries and propellers, and chargers. Flying is very stable, and it can be programmed with ArduPilot software.

Spider Leg Mechanism

This a project I worked on during Fall Semester 2017.

Class: Design of Mechanisms – Dr. Onur Bilgen
Project: Spider Leg Mechanism (Klann-linkage)
Purpose: Design and create a mechanism to emulate a spider leg walking movement

 

All white plastic parts were modeled in SolidWorks, then 3D printed at Makerspace. Metal parts were from a kit provided by my professor, except for white screws which I bought at The Home Depot.

The big plastic backing was necessary to keep parts in position. Mechanism was carefully modeled in SolidWorks to create the Klann-linkage, which was planned out using what was learned in class.  The linkage consists of one crank, two rockers, and two couplers.

The extra hole was originally used to hold a rod connecting a set of gears, which would be turned with the crank. This would’ve made it so that multiple sets of legs could be connected together. However, this idea was scrapped due to it taking up too much time and resources.

My Sleeping Issues

For a LONG time now (way too long), I’ve had a lot of trouble sleeping. Sometimes it would be hard for me to fall asleep, other times I would wake up hours before I should have.

I had the opportunity to do a sleep study after talking to my doctor last summer. However, it would cost at least several hundred dollars. So I didn’t want to because I thought I could solve it myself. I kinda did figure it out, but it wasn’t until months later. Meanwhile, I constantly felt tired and unmotivated.

So learn from me: Get your sleep straightened out as soon as possible. Even if it means spending money. It will be well worth it since sleeping is so important for brain function. You spend a large portion of your life sleeping, so INVEST IN IT!
