Step-by-Step Guide to Building Your DDR Dance Pad

Follow these detailed instructions to assemble your own high-performance ddr dance pad.

Preparing the Base and Sensor Locations

  1. Mark Guidelines: On the plywood base, mark a margin at the front edge. Divide the remaining area into a 3×3 grid of 11″ squares. These lines will serve as guides for sensor placement and component alignment for your ddr dance pad.

  2. Apply Copper Tape (Bottom Layer): Cut 11″ strips of copper tape and apply them to cover each sensor location within the marked grid. Overlap the strips by 1″ to ensure consistent electrical conductivity across the sensor areas of your ddr dance pad.

  3. Create Common Contact: Run two long strips of copper tape to connect the Left/Right and Up/Down sensor locations. Add two more strips to connect the Start/Select sensor areas. These strips, along with the Start/Select sensor copper, will form the common ground contact for your ddr dance pad.

Assembling the MDF Frame

  1. Glue MDF Corner Supports: Using wood glue, attach the MDF pieces to the plywood base in the non-sensor corners. Place the larger squares in the back corners, the smaller square in the center, and the rectangles in the front corners. Position them 0.75″ from the marked guidelines. Clamp or weigh down the MDF with heavy objects (like books) for at least 30 minutes to allow the glue to set properly, forming the structural frame of your ddr dance pad.

  2. Add Upper Corner MDF Strips: Glue the MDF strips along the edges of the upper corners. These will frame the Start/Select buttons and create a defined area for these controls on your ddr dance pad.

Installing Velostat Sensors and Metal Contacts

  1. Place Velostat Sheets: Position one Velostat sheet over each sensor location, ensuring it covers the entire copper contact below, except for the copper strip leading to other sensors. Gluing the Velostat is optional. Leave a small gap between the Velostat and the MDF frame, exposing a bit of plywood. This margin helps prevent accidental shorts and ensures proper sensor function in your ddr dance pad.

  2. Position Sheet Metal Contacts: Carefully place the sheet metal top contacts over each Velostat sheet. Crucially, ensure the sheet metal does not directly touch the copper tape. Verify the Velostat is free of tears and bunching to prevent shorts. The cut dimensions are designed to provide a margin of safety for your ddr dance pad sensors.

  3. Connect Top Contacts with Copper Tape: Attach copper tape from each sheet metal top contact to the inner cable channel area of the ddr dance pad. This will be the ‘hot’ connector for each sensor. Absolutely prevent this copper tape from contacting the common ground copper layer underneath the Velostat. If any copper is exposed where it shouldn’t be, use electrical tape to insulate it. It’s acceptable for the top copper layer to touch the Velostat.

Securing Sensors and Weather Stripping

  1. Duct Tape Sensor Sandwich: Use duct tape to firmly secure the sheet metal, Velostat, and copper tape layers together as a single sensor ‘sandwich’. Tape down all four edges of each sensor thoroughly, but avoid placing duct tape directly over the copper tape contact points. This creates a robust and sealed sensor unit for your ddr dance pad.

  2. Glue MDF Corner Mini-Strips: Glue the MDF mini-strips into the corners, leaving a small channel for wire routing. These strips ensure clean separation between the main step panels and contribute to the tactile feel of your ddr dance pad.

Wiring and Electronics

  1. Route Internal Wiring: Solder one end of a white wire to each ‘hot’ copper tape contact on the sensors. Route these wires through the internal channels of the ddr dance pad and out to the top side. Choose one side (left or right) for wire exits for cleaner organization. Leave ample wire length (8-12″ recommended) for connecting to the Teensy board.

  2. Connect Ground Wire: Choose a convenient point to connect a ground wire to the common ground copper tape layer and route it out to the top alongside the sensor wires.

  3. Secure Wires with Hot Glue: Use a glue gun to strategically place blobs of hot glue along the internal wires to secure them in place and prevent movement. Keep the glue away from the sensor areas to avoid interfering with step registration on your ddr dance pad.

Final Assembly and Testing

  1. Apply Weather Stripping: Split the weather stripping, cut it into 11″ pieces, and apply it to the top and bottom edges of each main sensor (excluding Start/Select buttons). Position the weather stripping on top of the sheet metal and duct tape, right at the sensor edges. This provides cushioning and defines the step areas of your ddr dance pad.

  2. Align Lexan and Drill Mounting Holes: Place the Lexan sheet down, ideally elevated slightly. Carefully position the pad (MDF-down) on top of the Lexan, ensuring proper alignment. Clamp all layers firmly together. Using a 1/4″ drill bit, drill holes through all layers in the four corners of the ddr dance pad. Marking the Lexan’s orientation at this stage is advisable for consistent reassembly.

  3. Install T-Nuts: Hammer T-nuts into the drilled holes on the plywood side of the ddr dance pad.

  4. Secure Lexan Top: Flip the assembly face up. Thread M5 screws through the Lexan and into the T-nuts to securely fasten the Lexan top to the pad base.

  5. Initial Testing: Your ddr dance pad is now mechanically complete! Test the step feel by pressing on each sensor. They should have a distinct, clicky feedback. If the steps feel too deep, adjustments can be made later.

Connecting the Brains: Teensy Board Setup

  1. Wire to Teensy Board: Cut new white wires and solder one end of each to the Teensy board’s analog input pins (pins 14, 16, 18, 20, 22, and 23, corresponding to A0, A2, A4, A6, A8, and A9). This pin configuration provides spacing for easier soldering. Solder the other ends of these wires to the internal wires coming from the ddr dance pad sensors. Use heat shrink tubing to insulate the solder joints.

  2. Install Arduino and Teensyduino: Install the Arduino IDE and Teensyduino add-on, following the instructions at https://www.pjrc.com/teensy/td_download.html. These are necessary for programming the Teensy board to function as the controller for your ddr dance pad.

  3. Upload Code to Teensy: Create a new Arduino sketch and copy-paste the provided code (link in original article – https://pastebin.com/Y1vNZ56K) into it. In the Arduino IDE, go to Tools -> USB Type and select “Serial + Mouse + Keyboard + Joystick.” Run the code to upload it to the Teensy board.

  4. Functionality Check: After uploading, test the ddr dance pad by stepping on each sensor. The on-board LED on the Teensy should light up when a sensor is pressed and turn off when released. If the LED stays lit when no sensor is pressed, check for shorts in your wiring.

  5. StepMania Testing: Connect the Teensy-equipped ddr dance pad to your computer via USB and launch StepMania. Test the pad thoroughly in-game to ensure all sensors are registering correctly and the pad is functioning as expected.

Finishing Touches and Graphics

  1. Apply Non-Slip Layer (Optional): If using a non-slip layer, cut it to size. Apply spray glue to both the non-slip layer and the plywood back of the ddr dance pad, then adhere them together.
  2. Install Graphic (Optional): Unscrew the Lexan top and remove the protective film from the inside face. Place your printed graphic face down on the Lexan, ensuring correct orientation. Apply spray mount adhesive evenly and glue the poster to the Lexan.
  3. Final Assembly: Use a utility knife to carefully cut notches in the poster for the screw holes. Reattach the Lexan sheet to the top of the ddr dance pad with the screws.

Your DIY ddr dance pad is now complete and ready for countless hours of DDR and StepMania enjoyment!

Tips for a Perfect Build

Here are some helpful tips to ensure a smooth and successful ddr dance pad build:

Cutting Sheet Metal and Materials

  • Sheet Metal Cutting: The easiest method for cutting sheet metal is to use a carbide blade utility knife. Clamp the sheet metal between a plywood backing and a yardstick. Score along the cut line repeatedly until the metal bends and breaks cleanly. File down any sharp edges, directing any burr upwards away from the Velostat layer to prevent damage.
  • Circular Saw Tracks: Consider using DIY or commercial circular saw tracks for precise and straight cuts on plywood, MDF, and Lexan. Ensure materials are securely clamped during cutting.

Accurate Cutting Techniques

  • Blade Selection: When using a circular saw for Lexan and plywood/MDF, use a blade with a high tooth count (at least 40T, ideally 60+ teeth) for cleaner cuts and reduced chipping, especially on Lexan.
  • Sacrificial Plywood for Lexan: For the cleanest cuts on Lexan, sandwich it between sacrificial plywood sheets. This minimizes chipping and cracking.

Customizing Your Dance Pad

This ddr dance pad design is easily customizable to suit your preferences.

Adjusting Sensitivity

  • Cardboard Shims: To increase sensitivity and soften the step feel, cut cardboard sheets (approximately 10″ x 11″) and place them on top of the Velostat sensors, underneath the weather stripping. Experiment with different thicknesses and layers of cardboard to achieve your desired sensitivity level. Double-sided tape can help secure the cardboard shims in place.

Fine-Tuning Step Feel

  • Weather Stripping Adjustment: Adding more weather stripping around the sensor edges can alter the step feel, making it potentially softer or more defined. Experiment to see if this suits your play style, though the original design found this less desirable for precise play.
  • Internal Foam or Rubber: Inserting thin rubber or foam sheets inside the sensor sandwich can dramatically increase sensitivity, creating a very soft, “ignition-style” feel. However, this can make precise play more challenging. Proceed with caution if considering this modification for your ddr dance pad.

Future Improvements and Wireless Dreams

  • Copper Tape Top Layer: For enhanced sensitivity, consider using copper tape on Lexan squares for the top contact layer instead of sheet aluminum. This “V4” sensor design improves responsiveness. You’ll need to adjust the trigger threshold in the code accordingly.
  • Lower Cost Lexan Alternatives: Explore options for reducing Lexan costs by using it only in the step areas. Developing a design that maintains proper step movement and edge-to-edge sensitivity with less Lexan is a future design goal.
  • Wireless Connectivity: Future iterations aim to incorporate Bluetooth wireless connectivity using boards like the Adafruit Feather HUZZAH32, creating a truly wireless ddr dance pad.
