EW Project 2: Presentation and conclusion

So the presentation went pretty well. After a little calibration with our 'garbage simulation ballasts' the system worked extremely well. It worked consistently and reliably. Here's us tinkering with the system with our chosen ballasts, cans of cool refreshing Coca Cola™. Here's us doing some last-minute tinkering:


And here's a link to the presentation: http://goo.gl/NW0Hgt

Overall I felt the presentation went really well. I think we conveyed the idea fairly effectively and the demo went off without a hitch. One thing we probably should have elaborated on a bit more was the reward system. 

Some future improvements to the system include:

  • Weekly or monthly scores. While doing it live is pretty cool, it can be wildly unreliable as it relies on the trash currently in the bin, which can vary so much. However averaging it over a longer period of time would produce a nice average score over the course of a longer, more representative timeframe/
  • Developing further on the first point, a semi-live system that only updates with full binloads. For example the weight of the bin only gets measured when each bin is about to be emptied. The score is then generated from the total weight of waste and recycling over the course of a timeframe.
  • An implemented government-sponsored rewards system providing tax breaks and other bureaucratic rewards to the companies that have the highest scores.
  • A third bin for compost. While recycling is great, composting is also another great way of saving the planet. The score would then be a lot more awkward to work out because compost biodegrades, however using some more advanced sensing systems i'm sure it would be possible.

Here's a render Stylianos made of what the system could look like:


The screen in the middle could be used to to display a number of things including the leaderboard of other local companies, incentivising the user to score higher than the other local companies on the through healthy competition. It could also be used to display statistics about the user's disposal/recycling habits. 

I felt the project went really well, I learned a lot about Node Red and I'm convinced that that is something I'm going to be using for my final year project along with the MQTT protocol. Node basically does almost exactly what I need for my project, albeit with a little hacking here and there.

Logitech G502 Proteus Core Teardown & Scroll Wheel Replacement

Image
So I recently acquired a Logitech  G502  mouse, and I have to say I absolutely love it. It's a beautiful mouse, and a worth upgrade to my old G500s mouse. However my one gripe was the new all-metal scroll wheel. While the weight was nice, I missed the rubber ring around my old 500s. This led me to attempt to replace the new 502 scroll wheel with the old one from my busted 500s. So let's get started shall we? So as you can see, these are what the mice look like side-by side. While they look drastically different, the ergonomics are actually very similar among the two. The first step was to take the mouse feet off and unscrew the screws that hold the chassis in place.  Lever the feet off gently with a flathead screwdriver. And they just peel right off. There's four screws on the underside of the mouse.  So the feet are layered. There's double-sided adhesive foam, with the feet on top. On the back foot, I managed to peel off...

Turning a laptop screen into an external monitor.

Image
So my old Dell L502x died. However most of the components were fine, it's just the motherboard that seemed to be down with a case of water damage. So along with turning the chassis of the laptop into a dock/stand for my new laptop I wanted to turn the laptop's screen into an external monitor. So the first thing I did was extract the panel from the housing to take a look at the model number and the interface. If you're looking to do this yourself just look up the documentation for your laptop or go to ifixit.com  and look it up. Fortunately Dell has excellent documentation and a pretty straightforward teardown process.

FYP: Accessibility, and Justification of Equipment

The next step was hooking up the master arduino to Hazel and have it listening out for the webapp's messages. This wasn't that hard as I'd already done it as part of my prior development in December. Unfortunately I was lacking a WiFly shield I had borrowed from the university at the time, and the university had all of the WiFlys booked out.  However part of the intention of this project was accessibility, the components needed to be cost effective and easily accessible. This cannot be said for the WiFly shield as it costs around $70 . The official Arduino WiFi shield costs around the same . Instead I actively opted to use an ethernet shield for a number of reasons: Price. A new third-party ethernet shield can cost less than £10 on ebay. The one I bought for this project cost £12.49 . I selected that one because it had UK distribution. Standardization. Nearly any third-party ethernet shield can be used with the Arduino's default Ethernet library. Ano...
