This three-axis motion sensor gyroscope is based on an Arduino Pro Mini


Maker Martin Cote has developed a three-axis motion sensor gyroscope that enables you to track head or arm movement, then reproduce it on servos. 


Initially conceived for head-tracking FPV goggles, Martin Cote has created a three-axis motion sensor gyroscope based on an Arduino Pro Mini (ATmega328). Applicable in a wide range of settings, users can track the movement of the head or arm, and replicate it on a set of servos.

Available in two different versions, both wired (Iota) and wireless (Z-ita), the gyroscope is ideal for Makers seeking an inexpensive head-tracking system yet are not comfortable with the advanced programming of accelerometers. Sample use cases include robotics, remote-controlled toys, gaming and interfacing with computers.

First, Iota provides users with the ability to control mini servos that reproduce movement on three axes, as well as reverse the direction of the servos to act as a stabilizer. Measuring just 1” x 3″ in size, the super small and lightweight unit can be easily integrated into any project. Meanwhile, Z-ita does pretty much the same thing but wirelessly within a range of 30 to 50. This set comes with the Ita receiver, which transmits the signals to the servos, as well as a battery capable of lasting of over two hours. What’s more, it offers a selection of 16 channels at the frequency of 2.4Ghz, and allows more than one to be used at a time.

“You want to use the accelerometer signals to another type of application? Get the Iota or Z-ita set and plug it into your Arduino MCU according to the video and use the sketch file provided (which you can adapt to your needs), and look for new possibilities to suit your needs.”

ATmega328P mods this console controller

Marcel Smith has modded and tricked-out a PS3 dualshock controller using an ATmega328P microcontroller (MCU).

Additional key components and features include:

  • Supports Arduino bootloader
  • 
Programmable via USB
  • Dual force feedback
  • 2.4GHz 60mW Xbee pro module (optional)
  • 2.4GHz Wi-Fi module (optional)
  • Low profile pinheader
  • Wireless module configuration via USB port
  • Open hardware/software
15 digital buttons
  • Two analog triggers
, two analog joysticks
  • 3.7V Lipo battery
  • USB auto battery charge
  • Borderline 0uA standby current

The modded device – which recently surfaced on Indiegogo – is aimed at DIY Makers and hobbyists interested in a versatile remote control platform.

“You can use and program the controller for robotics, RC cars, planes, helicopters, drones, boats, hovercrafts and FPV,” Smith explained.

“The controller uses an ATmega328P, the same as on the Arduino Uno. This makes it easy to adapt the Arduino platform on the controller. You can upload your sketches via the USB port. The hardware and software is open for everyone, this makes it possible to program your own functionality into the controller.”

Makers can also directly configure the Xbee/Wi-Fi module via USB using X-CTU by simply setting the UART software switch in the right direction.

“The controller sends serial messages to the USB port, so even without wireless module it is possible to control something like a game on your computer with the controller (force feedback),” Smith added.

ATMega32u4 powers Hex ‘copter

Hex – powered by Atmel’s ATMega32u4 – is a 3D-printed nanocopter that can be controlled using the gravity sensors in a mobile device.

“Hex imitates the movement of the smartphone or a tablet in the air. In addition, traditional throttle, elevator, aileron, rudder control systems can be used to operate your Hex,” the HexAirBot team explained in a recent Kickstarter post.

“Hex’s flight control system is paired with various sensors help to make flying more safe and steady. These components massively reduce the risk of crashing. The sophisticated electronics in the copter allow it to sense when Hex is not balanced and adjust the motor speeds accordingly.”

The Hex team also noted that the open-hardware ‘copter allows users to view the world from a different perspective, as a camera can be easily attached to the ‘copter for aerial photography and videography. Plus, with FPV (first person view) glasses provided in the Hex Spy Kit, aerial navigators can realistically experience the thrills and joys of being in the air.

Last, but certainly not least, Hex’s autopilot system allows the craft to auto-balance itself in mid-air, although the sam circuit board can be modded to balance other devices such as a two-wheeled robot car, fixed-wing aircrafts, camera gimbals and submarines.

In addition to Atmel’s versatile ATMega32u4, key Hex hardware specs include:

  • Propellers (size: 56×8.5 mm, fits shaft: 1.0 mm)
  • Motors (diameter: 7.0 mm, length: 20 mm, over 50,000 RPM)
  • Flight control system (Microwii Copter, MPU6050)
  • Flight Time: 7 minutes
  • Communication protocol: Bluetooth 4.0 (WiFi module for webcam)
