Yesterday I received a Raspberry Zero W, that for approximately $10 include Wifi and Bluetooth (byebye dongles) but no Ethernet port.
This post contains the instructions for configuring the Raspberry Pi Zero W so that he connects to the wifi network at the first startup of Linux, without wasting time (after that, you can log on via SSH).
Insert the SD in your Raspberry Pi Zero W, attach the power USB, connect your computer to the wifi, scan the network to find the raspberry IP address (i use lanscan on OSX) and you can connect via SSH (the default password is raspberry)
Recently I build an Oculus Rift like low cost alternative to simulate the original device.
I have a smartphone with hd screen and find on Amazon an interesting kit (2 lens, 1 strap). So, I build a lego structure to bring together this elements, and wrote a small ios app that show two view, one for eye.
The gyro and accelerometer sensor make possibile to track the head movement, so the last ingredient was to find an app that show multiple 3d view based on sensors.
I not find the app, so I wrote a small ios app that show 2 streeview frame, rotating the view point based on sensors. The result is simple and awfull 🙂
After some day of building, conding, and testing, I publish the first photo of my Lego Ruzzle Solver.
The robot use 3 NXT motors: one for x-axis movement, one for y-axis movement, and one for move the “finger” up and down. To decrease friction, the two movable parts of robot are supported on rigid wheels, like a bridge crane.
A curious thing: the capacitive touchscreen of the tablet require human fingers (attached to human body) to dispatch touche event. Because attach fingers to lego mindstorm motor require detaching fingers from my body, I have discover that conductive sponge is a very good alternative, and because vegetal sponge is conductive, I have buy it at supermarket for 1 euro saving my real fingers.
