FAB TABLE


Even though there were a few ideas & the thought of a lab-group project were there I finally decided on the first idea I thought of. Making a FAB-Table. Over the period of the course after every week, new ideas were coming to my mind. From just a dismantlable table, after every week I decided to add other things as well. Usage of other machines in the lab. Some smart furnitures has inspired me in the process of choosing this as my project.

What will it do?


Fab Table is a multipurpose table. As the name suggests, the table will have various features which can be developed in the fab lab. The table with the help of a PIR sensor detects movement of the user and switches on the LED strip once the user apporaches the table. It'll also have a plug point on it so that devices could be connected to it for charging and powering other things.
Future Scope - with the same concept I'm planning to make a table with movable parts for keeping the monitor and add a book shelf on top of the table etc.

Who’s done what beforehand?


I've watched a couple of videos online, which has various features on multipurpose SMART TABLES.
Reference1 Reference2 Reference3
I referred that for getting some insights. I'll be using my own design I'll be designing my own boards.

What materials and components will be required?


18mm Plywood 1800 Sensors and circuits 150+200+2500 LED Strip 3-D printed cases/handle 745 Laser-cutted boxes for keeping the sensors and battery 700

Where will they come from?


Most of the components are available in the lab itself. Might have to get the power transistor from the electronic component dealer in the local market as its not available in the lab. Or I might use motor controller board as the driver which is still not fixed. I'll discuss the same with my instructor and finalize this.

How much will it cost?


As of now I cannot estimate it accurately. Though it could be between INR 7k and 10K.

What parts and systems will be made?


A Table, board with PIR sensor, a 3D printed holder to hold the LED strip and small boxes to keep the boards inside. I've already made the table during the Computer Controlled Machining week. The box was made during the laser cutting week but the box was not a press fit, so I'll have to make slight dimension changes to this and make it a press fit. Other process remaining includes milling and programming of the boards, creating the LED strip holder, upholstery works and other creative final touch ups.

What processes will be used?


  • Computer Controlled Machining - For making the table.
  • Computer Controlled Cutting - For making the boxes to keep the boards.
  • 3D Plotter & Electronics work bench - For milling and soldering the boards.
  • Embedded programming - To program the boards.
  • Ultimaker 2 - To 3D print the LED strip holder.
  • Vinyl Cutter - To cut stickers to stick on my table.

    • What tasks need to be completed?


    Design, Mill, Cut and program the boards. Laser cut acrylic for press fit boxes to keep the boards 3D print the LED strip holder. Vinyl Cut the stickers.

    What questions need to be answered?

    The Threshold value to be found out from PIR Sensor. How to power the LED strip - as there is no power transistor here in the lab. Will I be able to use the use motor controller board successfully. Programming the board

    What is the schedule?


    Design works: June 1st,2nd & 3rd Circuit Milling and stuffing: 5th & 6th Programming the board: 7th June Computer Controlled Cutting: 8th & 9th June Final touchups, Documentation and remaining works (if any) : 10th to 14th

    How will it be evaluated?


    I'm not exceptional in coding. Fab academy is my first experience in CAD(Designing), milling, soldering and mainly - programming, so the project might have some drawbacks. Being said that, if the project is to succeed, then it should be a working prototype.
