Broken Atrix

Following on from Raspberry Pi, Motorola Atrix Lapdock and Arduino Hoody, the Atrix broke. That is to say, the Pi only switches on when the Atrix is closed. When tis open the power to the Pi shuts off.

Raspbian with OpenCV

Preamble

From Is there a Raspbian image with OpenCV 3 pre-installed?, these link only answers

Don’t get the wrong BNO055!

Preamble

The Bosch BNO 055 IMU – a combined accelerometer, magnetometer and gyroscope with a built in ARM processor – can support both IIC communication and Serial communication, via the IIC or UART modes. However, this question on SE.Robotics, Aliexpress bought BNO055 UART connection, brought to my attention that certain breakout boards for the BNO005 can not be used in UART mode (at least not without some rework of the board) and therefore are only compatible with Arduino but not the Raspberry Pi.

Flight Controller – PiCopter

Preamble

Instead of using a microcontroller based board, such as an Arduino, etc., for a flight controller, how about using a Pi based solution?

TP-Link TL-WN723N / TL-WN725N

Preamble

This question on SE Raspberry Pi, Drivers for TP-LINK TL-WN723N v3, piqued my interest, as I have a TL-WN722N.

Arduino IDE on Fedora Raspberry Pi

Preamble

Been having an uphill struggle getting the Arduino IDE running on Fedora 21 REMIX for Raspbery Pi 2B, see Arduino IDE on Fedora.

Trying to buy a Thai Pi

The unbelievable hoops one has to jump through to buy a Pi in Thai[land] from RS…

Raspberry Pi, Motorola Atrix Lapdock and Arduino Hoody

Preamble

I bought a Raspberry Pi in Thailand at the start of the year. I got it working with a Motorola Atrix Lapdock (Lapdock for Motorola ATRIX 4G 11.6″ Motorola AT&T) that I purchased new on eBay for about £70, from Israel.

Motorola Atrix Lapdock

It has a Hebrew keyboard and the brackets glyphs are on the incorrect keys, but apart from that it is fine.

I then built an Arduino Hoody (which is equivalent to an Arduino shield), as described in the Instructables guide: The Raspberry Pi – Arduino Connection by thegrendel, which uses an Arduino Mini Pro 3.3V.
