It looks like the Arduino-compatible PocketStar has reached the funding goal on Kickstarter.
The matchbox sized handheld looks pretty cool but I feel like the "neat" but too tiny to actually be useful device trend needs to start slowing down. While it is pretty amazing to see this much tech in a tiny device, I don't see much need for them.
If It does interest you, you can fund one for around $50 and Up...
I definitely think this device is cool and might be a nice addition to a collection for anyone who hasn't already jumped on board with similar devices. What does make this one interesting is that it has built-in WiFi.
