Are you crafting your own gadget and want to add wireless networking to it? You'll want to look into Spark's new Photon board, then. The stamp-sized peripheral lets you add WiFi to many devices without requiring a lot of technical know-how; if you can design a gadget in the first place, you can probably get it online. Spark sees it as a relatively easy way for artists, engineers and students to make internet-savvy objects. It's cheap enough that it won't hurt to try. The regular Photon costs $19, and those who want to put it into mass-produced items can get the P0 or P1 at respective prices of $10 and $12 -- all of which are bargains next to the Core's original $39 price.
