Nexus One/Arduino SmallSat satellite test launch video

Nexus One/Arduino SmallSat satellite test launch video

Matthew Reyes sent word that the RocketMavericks launch event on Saturday in Nevada’s Black Rock desert was a resounding success. Traveling 28K feet aboard James Dougherty’s Intimidator-5 rocket was a payload consisting of a Nexus One/Arduino SmallSat. Matthew and his cohorts Chris Boshuizen & Will Marshall are championing the use of smartphone components to lower the cost of deploying a satellite and expect it to become even more affordable with every revision.

Open-source, software-based GSM cellphone network

Open-source, software-based GSM cellphone network

In plain language, we are working on a new kind of cellular network that can be installed and operated at about 1/10 the cost of current technologies, but that will still be compatible with most of the handsets that are already in the market. This technology can also be used in private network applications (wireless PBX, rapid deployment, etc.) at much lower cost and complexity than conventional cellular.

TRRSTAN, the audio controlled cellbot

The folks over at cellbots.com are at it again. Meet TRRSTAN, a cellbot controlled via the audio jack on a mobile handset. The site is a little vague on the details, but whatever they’ve got going on should ultimately drive down the price tag. Add an approachable way to program it and you’d have yourself one heck of a low-cost robotics platform.

FM support on Nexus One

FM support on Nexus One

The Nexus One sports the same Broadcom chipset as the HTC Desire, which has FM radio support, though Google has yet to enable this feature on the handset. Luckily the Nexus One is pretty open, so naturally somebody like intersectRaven from xda-developers came along and released a kernel with FM support baked right in. You’ll have to install a custom ROM, but at least it’s possible.
