The 2Square2 model

The first development prototype model is a panel of four squares. This is the proof of concept for my final project. The game’s board is lighted with leds. A hall effect sensor reading an analog voltage is changed by the relation to a magnet. The distance of the magnet defines whether the leds are on or off.

Who's done what beforehand?
  1. board games project:
  2. Hall effect sensor project:

For the 2Square2 model:

The prototype model measurement is about 30*30*10cm, therefor I reused materials from the fablab. All the electronic components were available from the fablab stock with the exception of the led’s strip.

    Materials and components of the board:
  • 8mm Polyethylene
  • 2 layers of 8mm plywood
  • 1 layer of 3mm plywood
  • 4 hall effect sensors
  • 1 strip of 20 WS2812 Leds
    Materials of the game’s unit:
  • 2 layers of 18mm birch plywood
  • 4 disk made from 3mm plywood
  • 4 ball wheels
  • 2mm PVC
  • 1 industrial magnet 15mm diameter 3mm thickness
    Materials of the frame:
  • 4 layers of 18mm birch plywood
    Electronics BOM:
  1. 1x ATtiny44
  2. 2x 2x3 pin header
  3. 1x 20MHz resonator
  4. 1x 10kΩ resistor
  5. 1x 100kΩ resistor
  6. 1x 1uf capacitor

    Cost estimation for the full scale model:


***All the materials and components are from local suppliers except of the hall effect sensors which will be order from Digikey***

    For the prototype model I need to design and fabricate:

  1. The game’s board made out of different layers. A base layer laser cut for placing the leds and the sensors. A lifting layer laser cut so that it will insure the wires passing beneath the dividing layer. A dividing layer laser cut for creating the squares and the internal division. A top layer milled for light spread and for placing and navigability of the game’s unit.
  2. Bottom milled and top vacuum formed for the game’s unit.
  3. Four layers frame milled for the model.
  4. Circuit with output and input, milled PCB and soldered components.
  5. leds matrix.


The assembling of the game will be completed step by step. First testing the leds division and lights. Then, reading the analog voltage with the sensors, placing them and the magnet and finishing the game’s unit. finally, framing and packaging. I will develop the software for the game with accordance to each step.
