SMDuino helps Arduino fit into tight places

[Adam] was tired of plopping the same components over and over into his Arduino-based designs. He spent part of his weekend laying out a small board that would host everything he needed and could be built as a single component for all future projects. Above you can see the project he calls SMDuino, an Arduino clone that can be used Read the rest

Adding speech control to an old robotic arm

[Joris Laurenssen] has been hanging onto this robotic arm for about twenty years. His most recent project uses some familiar tools to add voice control for each of the arm’s joints.

The arm has its own controller which connects via a DB-25 port. [Joris'] first task was to figure out what type of commands are being sent through the … Read the rest

Cardboard framed tricopter

Talk about reducing the costs of a build, this tricopter uses cardboard as a frame and has one less motor than its quadcopter relatives. There are almost no details other than those shared in the video after the break so we’re just going to guess based on what we see (feel free to share your own insight in the comments).… Read the rest

Decoding, then cloning an IR helicopter toy’s control signals

[Mike Field] got his hands on this Syma S107 helicopter with the intention of hacking it. After playing around with it for a while he set out to build his own infrared controller for the toy. It seems there is some protocol information about it published in various forum posts, but he decided it would be more fun to … Read the rest
