The Carbon Origins Apollo data logger boardThis is the story of a group of college students who moved to the Mojave Desert, bought a house, painted it white, and turned it into a make-shift lab. Then they went out to launch rockets.

Electro18 posted a tutorial on how to make a portable digital optical tachometer using an Arduino Uno, an instructable here:

A tachometer is a device used to measure the RPM or Revolutions Per Minute of any rotating body. Tachometers can be contact based or non-contact ones. The non-contact or contact-less optical tachometers usually use laser or Infrared beam to monitor the rotation of any body. This is done by calculating time taken for one rotation.
FEATURES
It can measure RPM over 20k
Sensor range extends upto 7~8 cm
Displays Maximum RPM

network switch small4

by serasidis.gr:

Remote control your electrical devices through your local network or internet. The circuit contains one output (Relay) and one input (isolated input). The whole project was built by using arduino nano platform and an ENC28J60 ethernet module. It can be used the W5100 ethernet module instead of ENC28J60, by replacing the UIPEthernet library to Ethernet library.

Moreover, the control is made from the Android application I wrote and it’s available on Google Play (https://play.google.com/store/apps/details?id=com.serasidis.NetworkRelay).

The schematic diagram, arduino sketch, photos and demonstration video is on my web site:

It’s hardly been a month since we first heard of the impossibly cheap WiFi adapter for micros, the ESP8266. Since then orders have slowly been flowing out of ports in China and onto the workbenches of tinkerers around the world. Finally, we have a working project using this module. It might only be a display to show the current weather conditions, but it’s a start, and only a hint of what this module can do.

Since the ESP8266 found its way into the storefronts of the usual distributors, a lot of effort has gone into translating the datasheets both on hackaday.io and the nurdspace wiki. The module does respond to simple AT commands, and with the right bit of code it’s possible to pull a few bits of data off of the Internet.

The code requests data from openweathermap.org and displays the current temperature, pressure, and humidity on a small TFT display. The entire thing is powered by just an Arduino, so for anyone wanting a cheap way to put an Arduino project on the Internet, there ‘ya go.

ARglove

Arduino user Jubeso submitted to our blog an instructable explaining the 10 steps to build an input device for gaming.

The  Gravity Touch bluetooth glove  is specifically designed to interact with augmented reality glasses like the Google Glass, Meta, Moverio BT or with the VR headsets like Oculus Rift, Samsung Gear VR, vrAse, Durovis Dive:

Those new products are amazing and they need new types of input devices. This instructable will describe how to build your own “Gravity Touch bluetooth glove” and I will also give you some tips to build your own Durovis Dive VR headset so that you will be able to enjoy full mobile VR. Because this glove will be of most use for VR game, I have created a Unity3D plugin for Android that handle the communication between your app and the glove. It means that you will be able to use your Gravity Touch glove to interact with your Unity3D VR game.

The Arduino code and the Java class I wrote to handle the communication between the glove and the Android device will also be available so that you will be able to adapt them for your need.

 

The bill of materials, among other things, contains an Arduino Micro , FreeIMU – an Open Hardware Framework for Orientation and Motion Sensing and 3m of flexible soft electric wire.

Makercon14
Right before the weekend of  World Maker Faire in NYC, Massimo Banzi will be at MakerCon with a keynote taking place on September 18 at 11 a.m local time. Makercon is a 2-day conference by and for makers organized around 4 specific tracks: Business of Making, Education, Maker Community Building, Tools of Innovation&Technology.

Makercon connects individuals at the forefront of the maker movement, focusing on the technologies, services ecosystem, manufacturing models, and funding trends that provide new ways of making things and getting them to market.

On Wednesday, September 17 at 7:30pm (after the Innovation Showcase) MakerCon will be able to watch the exclusive New York premiere screening of the acclaimed Neflix documentary Print the Legend. Right after the film, Dale Dougherty is moderating a panel discussion with some of the key players from the film.

SCHEMA-ELETTRICO-500x478

By Christian Granvillano @ open-electronics.org:

Today we’ll explain how to exploit the potential of Arduino as a programmable logic controller, connecting it to appropriate interfaces for I/O.

The PLC (Programmable Logic Controller) has been and still is the basic component of the industrial automation world. The Industrial application made the PLC systems being very expensive, both to buy and repair, and also because of the highly specific skills requested to software designers to extract the maximum potentials from controllers. Arduino is a kind of universal programmable controller, although it is only the “core” and in any case it has been built for general applications; with a little of external hardware (essentially interfaces capable of transferring signals from sensors and to actuators, reducing the EMI which may damage the microcontroller) and an appropriate software may, however, become something very similar to a PLC.
