HOWTO defeat the DRM on your coffee-maker

By Cory Doctorow at 1:42 pm Saturday, Feb 19

If you've got a Senseo coffee maker -- the kind that takes little proprietary, pre-measured coffee "pads" and converts them to hot mud -- then you've got a DRMed kitchen appliance. Those little pads contain countermeasures to keep them from being refilled and/or replaced by third-party coffee delivery-systems. This HOWTO explains how to circumvent your coffee-maker's DRM and roll your own pads.

Step 1: find the right glass
You’ll need a glass with a round bottom that’s just the size of a Senseo coffee pad. This shouldn’t be too difficult.
Tip:It doesn’t really have to be a glass, but it helps if you can see what you’re doing. Go out and buy a glass of the just right size if necessary.

Step 2: draw the filter shapes
Lay the tea filter bag flat on the surface. Place the Senseo-sized glass on top. Use the pencil to draw a circle on the filter. Read step 4 to help you decide where to place the glace and draw the circle.
Tip: Do not substitute a pen or marker instead of a pencil. You do not want ink or mystery chemicals in your coffee. Even so, use a soft pencil to avoid ripping the fine filter fabric and don’t push too hard. You do not want graphite in your coffee either.
