Most custom steel rule dies are likely to run easily in the $50 to $100 range. Larger and more complex dies than the heart example below easily run several hundred dollars for a 1 up die. Actually cutting your project will range also in the $50 to $150 range per batch up to 1,000 units. There may also be additional design fees or prototyping fees required depending on the project. If that hasn't scared you off, you are ready to investigate a custom job involving a custom steel rule die.

We highly recommend you investigate your local craft store or scrapbooking club to see if they have some of the hobby die cutting tools that might meet your needs.

To decode what the remote was sending, I used an oscilloscope and a small photodiode. The photodiode generates a small amount of voltage when light hits it, and responds to changes in light level quickly enough that the oscilloscope can draw a really nice plot of the signal. I have a Parallax USB oscilloscope, which is perfect for showing the command pulses and is just fast enough to find the modulation frequency. As an aside, I’m really happy with the Parallax oscilloscope for projects like this. It is simple to use and I love being able to save images to share with people.
Here’s what two of the commands from the dimmer remote look like. The top signal is the “fade lights up” command, and the bottom one is “fade lights down”:

When I push [my toaster] lever down, if there's a crumb stuck in the coils, it isn't long before my fragile pre-coffee state is shattered by the piercing siren of my smoke detector. It doesn't know about the toast, but really it should. If it were sociable, as soon as it detected particulate matter in the air, it would query the toaster to see if it had been activated. That would tell it that in all likelihood, it wasn't detecting an unattended, middle-of-the-night fire but instead a benign morning meal. The price of low-power radio networking and the just-minted funding for smart home energy networks makes this sociable smoke-detector scenario entirely within our reach. I want one.

"Pre-Production Design (with an emphasis on project management) ------------------------------------ The following document steps through the pre-production process. The steps are roughly in the correct/ intuitive order, although some will overlap. If you manage to address each one, you should be able to generate a cohesive design document that will serve to provide an exhaustive reference for both technical design and creative direction throughout the production process. It will demonstrate your knowledge of the target demographic and will communicate your enthusiasm to the client. Define client goals"
