For my new part of final project “the coffee table”

I changed the idea of my final project to a Smart Coffee Table

before I begin I would like to acknowledge and thanks again the main source and the designer of the table Rob Hemsley where I used and developed the design that he started with. For more details on the additions I made to the design please visit the following link Week8 "Computer-Controlled Machining"

To see how I created the table and the first skitch of the coffee table you will find it in the link provided as well .

Well, I added the lower part of the table to strengthen the joints of the table so the table.
Another thing why I decided on that lower shape because I didn't want to change the look so I went for a design like another shelve for the table.

Ok, the new part which I already gonna add is in this skitch.
I used Fusion 360 to draw the lower part as I did in first parts as well.

design ready for the ShopBot

I changed the lower acrylic part of the table because I needed to change the slots size and I changed the vector design of the acrylic part as well.
What happened?! I chose an Islamic vector design but I wasn't aware of whether its open resource or not. After Wendy and Hashim checked that and asked me to check the license of that image I discovered that I can not take that design.!!!

I took another design which is free open source vector from freepik

Editing the image using CoralDraw to create a vector.

This doily will be engraved by laser machine on a transparence acrylic material.

Adding a new joint to the table for better holding of the table's parts.

Some changes have been made to the additional part of the table or the joint as it will greatly help to fix the rules and parts of the table. Editing in Fusions 360 and adding some fillets in the corners for batter finishing.

ShopBot, operate the machine where it starts by changing the tooth

Sanding the edges of the joint

The electrical part of the final project and making the circuit board using Eagle. Well, I designed the board with both input and output in one board because I wanted to save the space used in the table and not showing a lot of electronic parts in the table.

The image has been saved at 2000 pixels resolution.

I added the circles on the outline layer to help me put the board in the appropriate place easer.

I began to solder the parts of the board and connect the wires of the neopixel strip.

I began testing the board at the table and focused on the frequency range of the ir sensor. I did the test in a different light environment "room with ligh and without light" so I have good readings to select the correct reading for the sensor before I move to the programming part of the board.

Test NeoPixel Strip

So, what I am doing here to test the RGB LED for my final project, I used an Arduino Uno for testing first, NeoPixel Strip, 3 wires to connect. visit the output week to see some tests I did with RGB LED

The neopixel and ir sensor are working successfully togather :) ..

I began programming the board with help of my colleagues in the lab .. Hashim and Salama, where I learned a lot of things in programming and electronics from them. So, I used Arduino software and by connecting my board with Wendy's ISP which most of us used it to programme their boards actually. I used her ISP because mine wasn't working and did not have lote of time to do new one again.

Placing the board in the 3D case I made to attach it under the table. This is the first box I made and then I did edit because I added some part to hold the acrylic cover and I made some open spaces for the FTDI and the headers as well.

This is the finished box fot the boared.

So this is how the table will look like and the way the sensor works in its final form.

Thank you very much Darshan for the interaction and cooperation with me in taking this nice photo.

Another thank you very much to Abdullan for the interaction and cooperation as well.

Final Project Presentations slide and video in 20 Jun 2018


- Modifications and changes developed after the presenting my final project -

I liked to add to the table some adjustments that I took into account after the final presentation of my project. As I have cut another new table with the additions of the slots on the legs of the table to hold parts more stronger than before and make it press fit which made a huge difference. This design of the proposed openings was with the help of the instructor Wendy. Also changing the area under the piece of acrylic smaller to stuck the piece from moving.

-As you can see, this is the part that has made a big change in the cohesion of the table parts.

- You can also see the addition of the curve/ fillet at the edges.

-The final shape of the table where the bottom can be used as a small carve means more beauty.

The design file is already included in the previous zip folder.

The coming update will be on the displaying the table in our lab with LED, All will be in function mode.
