PiStorms powered from mains current

  1. Hi,
    I'll would like to make a robotic project with PiStorms  that does not change "move" (I mean, it has robotic arm, but it is not a vehicle). For powering it, I'll like to connect it directly to mains current instead of using batteries.

    I see that connection with a transformer is one of the three power options that you show  in PiStorms webpage    /content/78-pistorms-lego-interface

    But I am unsure on how to connect it. I remember that there was a "how to" article about it, but I cannot find it.

    Also, I plan to use the following transformer, the official Lego 45517 transformer (10 V) that I use for my lego 8878 Power Functions Rechargeable Battery Box
    Is this transformer suitable for use with PiStorms?

    thank you!!

    What is the current output of this transformer? You need 1.5 to 2 amps of current to run PiStorms.
    Especially if you have any motors connected. If the current output of that transformer is low, it might cuase Pi to reset while running motors.
    Also, 10 Volts is bit high, it won't damage PiStorms, but you might get screen flickers.

  3. Upss, I chekced it and it delivers a current of 700 mA, which is too low.
    I see that I'll need to buy one to do this.
    What are the recommended voltage and current intensity?

    thnk you!!

    For PiStorms we suggest 9 volts, 2 amps DC transformer.
