Proximity Speech Alarm using Gadgeteer

Here I show how to create a proximity speech alarm using Gadgeteer. Basically, it yells at you if you get too close. This project uses the following components: FEZ Raptor Distance Sensor 8Ohm Speaker Emic 2 speech synthesis board GHI extender module Here it is assembled:           Here’s a video of the final project: The source code can …

Marquee Lights using 74HC595 with Gadgeteer

I saw an example of someone doing marquee lights using *duino and 16 putput pins. I wanted to reproduce it using Gadgeteer, 3 pins, and a series of 74HC595s. Here it is: Marquee Lights using 74HC595 with Gadgeteer. This uses the following components: FEZ Raptor 16 LEDs 2x 74HC595 200Ohm resistors A ton of wire The setup looks like this:     …

Web reporting range sensor

This week I’m combining two previous projects using the range sensor and wifi modules. This is a distance logger which can be queried via web. Once a button is pressed, the networking stack is started and the webserver is started. The distance module starts recording when anyone gets closer than 50cm. A simple webserver can be queried to get the …

Gadgeteer Joystick 2.1 Example

The Joystick 2.1 module from GHI Electronics is a fun and easy to use joystick controller.  Joystick controllers feel like they’re going the way of the dinosaur because of touch screens. However, they’re excellent for teaching velocity based movement across a screen within a boudary.  This is basis for all games. The code can be found on my Gadgeteer GitHub repository.  You …

Gadgeteer WiFi RS21 Server

The WiFi RS21 module from GHI Electronics is an excellent and easy to use module for settup at WiFi connection.  However, it’s a little tricky setting up a server application. You need to get the IP address assigned to the module from the dhcp server.  This is  done in the NetworkAddressChanged event before you join the network. I’ve uploaded the …

Gadgeteer Examples

Gadgeteer is an open-source hardware implementation using the .NET Micro Framework from GHI Electronics. GHI provides some excellent code snippets for many of their Gadgeteer modules. However, they don’t provide any full working solutions. My open Github Gadgeteer repository has many Gadgeteer examples of their modules with full working Visual Studio solution files. Please contact if you want a specific …
