    • "We've put it in a user-installable module. The user buys the card and just plugs it into any device that has a slot," Fiennes explained." All a developer needs to do is add a socket and a 3-pin Atmel ID chip to their product. That's 75 cents: 30 cents for the ID chip and 45 cents for the socket." This assumes the availability of 3.3 V. "But given that most things you want to control from the Internet are electrical, we think that's reasonable," he said. If not, developers can include a battery.
    • Fiennes demonstrated a power adaptor with an Imp socket. He installed a card and an appropriately labeled block appeared in a browser window. Fiennes plugged in a chain of decorative lights and we clicked on the box on our browser. After clicking, the box text went from "off" to "on." Over Skype, we could see the lights had come on.

      Fiennes emphasized that control need not be manual and could be linked to other Internet apps such as weather reports, or to Electric Imp sensor nodes that monitor conditions such as humidity.

      A second example is an Electric Imp enabled passive infrared sensor. Fiennes demonstrated how it could be programmed to report the time and date of detected motion to a client's Web pages on the Electric Imp server. In turn, those pages could be programmed to send an alarm to a mobile phone. The alarm could also be triggered if no motion was detected, allowing the sensor to serve as a monitor for the elderly in their homes, for example. If there is no activity before 9 a.m., a message is sent to a caregiver.
    • The final example is an Electric Imp washing machine. Machine operation can be made conditional on a number of variables, including the price of electricity. "Every washing machine has microcontroller and that microcontroller has a lot of data," said Fiennes. "That data could be sent back to a washing machine service organization that could call the client up before the washing machine breaks down."
    • The cards will be on sale to developers by the end of June for $25 each and Electric Imp will also supply development kits that include a socket, ID chip and power connection on a small board for about $10. While these are intended for consumer electronics developers Electric Imp is happy to sell them to students and non-professional developers. "Hobbyists can play with it and tell us what they think."
