Some may have seen my article, “Using WS2812B Addressable RGB LED Strips with Arduinos“, back in September? As can be seen in that article, controlling Addressable LEDs is pretty straight forward with a basic knowledge of the I2C protocol. I had planned to cobble together interface to allow RGB LED Strip to be Controller by either a LEGO Mindstorms NXT or EV3 Brick, but my teaching commitments and over projects seemed to have forced the idea onto the back-burner. Thanks to Mindsensor, I have no need to warm up the soldering for the idea as they have come up with a ready assembled interface.

I have spent the weekend experimenting with my Raspberry Pi’s. One challenge I set myself was to get a Sony PS2 Dualshock Controller working with Raspberry Pi. The main reason for this, was to allow me to control a BrickPi Robot without using a Mindsensors PS2 Controller Adapter connected to the Brick Pi. This leaves access to the maximum number of four NXT Sensor Ports on the BrickPi Board.

I have received a pair of Mindsensors’ GlideWheel-Ms, [powerfunction] Motor Controllers to Beta-Test. The GlideWheel-M is a motor controller for [powerfunction] (PF) Motors that allows you to connect [powerfunction] Motors to NXT Motor Ports. Using the built in encoder, the GlideWheel-M, allows rotational control of [powerfunction] Motors.

This Lego Mindstorms NXT Appliance Controller allows you to turn on-and-off your Household mains powered equipment such as lights, radios, heaters, etc. All via your Robot. Using this Controller in conjunction with a Lego Temperature Sensor you can control your aquarium, and even as a incubator control to hatch out bird eggs.
This project needs a lot of care during construction due to the Voltages involved.

120-240V A.C. KILLS!
