Playing with Mountaineer Ethernet Mainboard

Posted by Marco Minerva In these days I’m making some tests with Ethernet Mainboard, a Gadgeteer compatibile mainboard that is produced by the Mountaineer Group. Here it is the main characteristics of the mainboard, as described at http://www.mountaineer-boards.com/home/ethernet-mainboard: “Red mainboard” powered via USB 168 MHz STM32F407 microcontroller with 192 KB RAM and 1 MB on-chip Flash 8 […]

Using voice commands to control a servo

Posted by Marco Minerva I’m very interested in combining .NET Gadgeteer devices with other techonologies. In this post I’ll show how to use the Microsft Speech Platform to recognize speech and send commands to control a servo. Let’s start with the Gadgeteer device. We’ll use the HiTec HS-311 servo, the same that has been described […]

Creating an UDP Server with .NET Gadgeteer

Posted by Marco Minerva Some time ago, we presented a simple TCP Server for .NET Gadgeteer, that has been used in many other projects. Today, we’ll see how to create another kind of server, based on UDP protocol. Its behavior is similar to the one of our TCP Server, but it is simpler because with UDP we don’t have to take […]

Making Mayhem with .NET Gadgeteer

Mayhem is an open source application that supports triggers, events, and reactions.  The core Mayhem application runs on a PC, but the events and reactions it uses are interoperable with just about any platform or device.  The guys making Mayhem say that non-programmers can use it to automate anything!  This seems an invitation to try Mayhem with .NET Gadgeteer. Here’s a screen shot […]

XBee Control of .NET Gadgeteer Robot

The code in this brief example is part of an investigation into bandwidth and latency of XBee radios used for remote control.  I’d be interested in any other experiments with XBees.  If you have something, we can discuss a guest post.  There are several versions of this robot now.  The original by Eduardo Velloso uses light sensors and can be controlled […]

Constructing a Bluetooth controlled Robot

Posted by Marco Minerva In this post, I’ll show how to construct a robot with .NET Gadgeteer and how to control it using a Bluetooth connection from a PC application based on the 32feet.NET library. Let’s start from .NET Gadgeteer part. The base of our robot is the Rover 5 Tank Chassis, that provides two […]

.NET Gadgeteer Bluetooth to Control Relay Circuits

Here is a simple adaptation of Marco Minerva’s previous example: Controlling a Gadgeteer device using Bluetooth Module and 32feet.NET library.  This application uses the GHI Electronics Bluetooth Module to control the relays on a Seeed Relay Module.  You can use this scenario to turn on lights, start a motor, or start or stop any electrical […]

XBee Radios in .NET Gadgeteer Devices

XBee radios are inexpensive and they can be embedded in all kinds of devices.  XBees can be networked so that a failure of one radio does not impar communication between and among others in the network.  Their range exceeds that of Bluetooth connections.  The article Zigbee Networking with XBee Series 2 and Seeed’s Products provides a quick overview of XBee […]

Mind Control of .NET Gadgeteer Device via Neurosky EEG Sensor

This experiment leaves much to the imagination, but it does demonstrate how wave forms of the human brain can determine events on a device with an embedded microcontroller.  This code scenario is submitted for use in the Open Health and Fitness Data Aggregator project headed by Ira Laefsky. The Neurosky Mind Wave sensor is an economical electroencephalograph designed for extensibility with other applications.  For less […]

Controllare un motore con .NET Gadgeteer e un potenziometro (Italiano)

By Mike Dodaro, translated by Marco Minerva from the original English version Il modulo GHI Electronics Motor Driver L298 fornisce un metodo per impostare la velocità di due motori che possono funzionare contemporaneamente: MoveMotor(Gadgeteer.Modules.GHIElectronics.MotorControllerL298.Motor _motorSide, int _newSpeed). C’è anche un metodo per aumentare la velocità in un certo intervallo di tempo: MoveMotorRampNB(Gadgeteer.Modules.GHIElectronics.MotorControllerL298.Motor _motorSide, int _newSpeed, int _rampingDelayMilli). Questi […]

Eduardo Velloso completes Beta Driver for .NET Gadgeteer Bluetooth Module

Since the Bluetooth Module was released by GHI Electronics there have been numerous users who have found it difficult.  The starter driver was rudimentary.  Windows and other devices could not discover it or connect to it unless a developer who knew a lot about Bluetooth protocols implemented the Gadgeteer device.  The references available were manufacturer specifications. GHI Electronics invited the community to […]
