  • Happy hacking again!

    Anybody out there?

    I guess no. Anyway. I’m back again :-)

    The robotic arm project is not dead, I simply changed the design to give it more useful movements, and now I have to find out a way to attach the servos so the joints are strong enough to allow doing some nearly-serious calculations…

    Meanwhile, I’ve been busy, and the next project that sees the light around here is a flash trigger that, hopefully, will allow me taking high-speed photographs without having a high-speed camera :-)

    You can get all the details here. Hey! I even have a video of it!!

  • Board and wires

    Date: 2008.05.17 | Category: Projects, Robotic arm | Response: 0

    While we wait for the servos to arrive from Hong Kong, we can do some soldering work and set up some wires for connecting the servos to the Arduino board, using a prototyping board as a bridge for all the connections:

    As you can see in next picture I built a connector with three pins together on a side (where the servo will be attached) and three separated ones on the other side, that will go to the protoboard:

    We’ll need one of those for each servo. The red wire is for power in (5V DC), the black one is ground and the yellow one is for the control signal. Be careful and check that the servos you are going to use have this wiring, and in other case change as necessary your home-made connector, to avoid plugging 5V into the control wire of the servo.
