SSD1309 2.42″ 128×64 OLED Display wiring

Standard

I have gotten a bigger 2.42″ OLED display from Aliexpress. I got the 16pin version instead of the 7 pin one.

This is the copy of the SSD1306 that Adafruit sells and the same library works with it. It supports 8bit, I2C and SPI. The only problem I had was with the wiring for I2C. As usual, Aliexpress sellers do not offer any documentation or help. I managed to find some schematics online.

Visualizing L3G4200D gyro movement with Blender

Standard

I have purchased a rather cheap gyro L3G4200D sensor from eBay that can detect 3 axis rotation and deliver it through an I2C or SPI interface. I tried to use it to detect horizontal and vertical rotation in real-time. This turned out quite difficult as I could not visualize what the Gyro was outputting. I needed a visualization. I ended up using Blender to visualize the gyro that is connected to an Arduino Uno. With this combination, I got a real-time report that turned out pretty good and proved the sensor to be quite accurate at what it does.
