Double the volts… double the fun!

Preamble

For a long while I have wanted a Taurino Power 24 volt controller, and although they seem hard to find now, there is the Eruduino, which seems to be a reasonable clone…

Using 24 volts over 12 volts means, basically, less (half) current, thinner wires (or less likely to burn out the existing wires), less stress on connectors (where most fires start).

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.

Making your own ArduinoBoy

Preamble

Following on from ArduinoBoys and others and Scaling PDF for PCB, here’s a step by step guide to making Trash80’s ArduinoBoy, on a PCB. For a photographic guide, see ArduinoBoy build.

Obviously, you don’t have to use a PCB and you could make the ArduinoBoy using stripboard/veroboard, ProtoShield, or even on a breadboard… see at the bottom for a suggested layouts.

BTW, I assume Trash80’s moniker is a nod to the Radio Shack TRS-80?
