Four principles for the open world

 Don Tapscott: Four principles for the open world

We get asked why [nwazet builds Open Source Software and Hardware all the time: in this TED talk, Don Tapscott captures the essence of our belief in ‘Openness’.



Seattle Mini Maker Faire: [nwazet demos source code / designs

We just updated our BitBucket repository with the  source code of the demos and supporting drivers, libraries and designs that we showed at the Seattle Mini Maker Faire a few weeks ago, including:

and the supporting bits:
  • Nwazet Adafruit Max6675 Thermocouple amplifier C# driver
  • Nwazet RGB LED Display driver for the Adafruit LPD8806
  • Nwazet Joystick module STM8S C driver
  • Nwazet Joystick module Eagle schematics / board layout
  • Nwazet Joystick module C# driver
  • Nwazet SerialLib message handler

We hope that you will find this code fun and useful in getting started building real applications with Netduino Go! today: with a little bit of creativity, it is easy to adapt a wide variety of existing hardware components for integration with Netduino Go!

No need to wait: just jump in and start building and integrating 🙂

[nwazet Nutshell – Visual screen designer and C# code generator

We all know that designing a polished user-interface by crafting code can be a slow and tedious process. So, we created a visual design tool called Nutshell for our Netduino Go! Touch Display moduleNutshell offers access to most of the features supported by the Touch Display’s API and generates the corresponding C# code on the fly for you. Just copy/paste the resulting code in Visual Studio when you’re done!

You can use Nutshell without installing anything since the tool runs JavaScript in your web browser.

You’ll never go back to the old way of crafting a user interface on your Netduino microcontroller after you discover Nutshell Posted Image
Here’s a tutorial showing how to build a screen in Nutshell

We’ve got the power! (for your Netduino Go! projects)

We just received our new Power Supply Module from the assembly house 🙂

It is the easiest way to power your Netduino Go! projects away from a computer once you’re done building it. The module will fit nicely on the top-left corner of our Large Plate or of our Stackable Plate. This module is equipped with a standard center-positive 2.0mm barrel jack and will take any power supply, such as a wall-wart, a 9 volt battery or a cigarette-lighter adapter, between 7 and 20 volts and will output a nicely regulated 5 volts at up to 800 mA. Just connect the micro USB cable that you’re using today with your Netduino Go! to the power supply module and you’re good to go. The module also features a large switch to let you turn your project ON / OFF smoothly and easily.

Power Specifications

It’s tiny but packs a nice punch:

  • Voltage Input: 7v (min) to 20v (max)
  • Voltage Output: 5v regulated
  • Current Output: 800 mA (max)
  • 1.0v Dropout
  • Barrel Jack: 2.0mm diameter with the positive voltage at the center


  • The hole-to-hole dimensions of the module are 30mm x 25mm
  • The total size of the board is 40mm x 35mm
Hacking the Netduino Go! for power-hungry projects

We will follow up soon with a post showing how to take advantage of the 800 mA provided by the [nwazet Power Supply Module going beyond the 500mA imposed by the USB power circuit on the Netduino Go!



[nwazet Touch Display Module – 3 Step Assembly Procedure

 This tutorial will walk you through the [nwazet Touch Display Module assembly procedure that we recommend following. When shipping out modules, we want to be sure that they will be safe during their transport. To this end, after testing each one, we pack the touchscreen in its OEM case, which provides the best protection.

The side of the module where the touchscreen needs to be fitted is marked with a white silkcreen frame with a section of VHB (Very High Bond) double-sided tape at the center:

Step 1

Gently lift the brown plastic flap of the Hirose connector and push the flexible touchscreen connector into it until it is squarely fitted at the end of the socket. Then, secure the touchscreen connector by slowly closing the flap until it ‘clicks’ shut. The cable should feel snug into the Hirose socket and the flap should be flat.

Step 2

Flip the module over and peel off the plastic sheet from the VHB tape.

Step 3

Using the white dotted silkscreen frame as a guide, center the touchscreen within the frame. Only stick the touchscreen onto the VHB tape once you’re satisfied with the alignment: the VHB tape is extremely sticky and is designed to create a permanent bond between the module’s PCB and the touchscreen after curing for 24-48 hours at room temperature. Press and hold the touchscreen against the VHB tape for a good minute to create a solid initial bond. When pressing the touchscreen onto the VHB tape, hold the edges of the display. Never press hard on touchscreen during the assembly procedure or you could crack it.

Finally, peel off the protective plastic sheet from the touchscreen:

Your [nwazet Touch Display Module is now ready for action!
