Step 1: Get the Ingredients
For this instructable you will need:
- a computer running Windows, OS X or Linux
- a webcam
- a printer (ink-jet for best results)
- A4 paper
- 5 or more A4 sheets of thin printable cardboard (e.g 180 g/mm2)
- 4 pieces of size A4 or bigger of corrugated cardboard 3-4 mm tick; this can be obtained from used cardboard boxes
- paper & cardboard cutting tools (scissors or knife)
- paper & cardboard glue
- adhesive tape or masking tape
- the d-touch drum machine software downloadable for free from http://www.d-touch.org/audio/
- a network connection (this is for our research, see above)
- lentils or other small beads
Step 2: Download & Print Blocks
Download the d-touch drum machine blocks pdf: http://d-touch.org/files/drum_machine_blocks.pdf.
Print it on thin cardboard. For best results use an inkjet printer.
Step 3: Cut & Fold the Blocks
Cut along all dashed lines, paying attention to the small segments.
Fold each block along the solid lines.
Step 4: Glue and Close
Glue the flap and close each block.
Step 5: Fill With Lentils
Fill the blocks with lentils to make them more heavy.
This step also augments the blocks sound making potential.
Step 6: Print the Camera Stand Files and Glue to Corrugated Cardboard
Download the camera stand pdf file: http://d-touch.org/files/drum_machine_stand.pdf and print it on normal paper.
Glue each of the pages to a piece of corrugated cardboard about 3mm tick.
Step 7: Cut the Stand Parts
Using a knife cut the cardboard along the dashed lines on the printout. Make a half cut along the solid lines, so that it will be easier to fold along them.
Assemble the camera stand as shown in the photos.
Step 8: Setup Camera on Stand
Place two heavy books, or other heavy objects, on the flaps at the bottom of the stand to make it more stable.
Attach the webcam to the stand using an elastic band.
Step 9: Print the D-touch Drum-macine Board
Download the drum machine board pdf file: http://d-touch.org/files/drum_machine_board.pdf.
Print it on normal paper. For best results use an inkjet printer.
Step 10: Download and Activate the Software Application
Create an account on http://www.d-touch.org/accounts/register/.
Download the d-touch drum macine installer from our website, here are the links:
Windows installer: http://d-touch.org/files/D-Touch_Drum_Machine-0.1.exe and
OS X installer: http://d-touch.org/files/D-Touch_Drum_Machine-0.1.dmg.
Installing should be straightforward (if it's not please let us know on our forum! http://d-touch.org/forum/audio/)
Launch the configurator application. Go to the activation tab, enter your username and password and click on "activate". Make sure that the "activated" message appears under the password field.
If appropriate use the other tabs in the configurator application tune the parameters for your audio card (otherwise leave the default values).
Click on OK to close the configurator.
Step 11: Start the D-touch Drum Machine Application
Start the d-touch drum macine application.
On OS X a configuration dialogue for the camera will pop up, please select the appropriate options or leave the defaults, and click on OK.
You should have a window showing you the view of the webcam (in grayscale).
Adjust the paper and the webcam so that the four corners of the board are in view.
Step 12: Fix the Board to the TableI
If possible, fix the board to the table using some tack, or some masking tape.
Step 13: Adjust Focus and Light
Adjust the camera focus and the light in the room so that the four calibration markers at the corners of the board are recognized and highlighted.
It is best if they are stable, but it can be ok if they blink a little.
If you see a large rectangle in the centre of the image, this means that the application does not see anything :-( please try to adjust light and focus until the rectangle disappears.
Place some blocks on the board and check that they are recognized and highlighted, if not try adjusting the focus and light again. It is best if they are stable, but it can be ok if they blink a little.
