I have been using the BPI-216N/L Serial Text LCD for years. The COM port interface is about as simple as you can get.

It's a bit pricey and you can get something better with a serial interface for about the same price (look under Intelligent Display modules),

I have the older version of this module and it is a very readable display.

You can also use,

byte B = 0xac;
String S = B.ToString("X2");
Debug.Print(S); //--> AC

You need to add,

using System.IO.Ports;

I was using this with an ESP8266 AT command set driver (since abandonded in favor of the Lua firmware). Just instantiate the port without an event handler and then receive serial in a wait loop.

Public Sub New(ByVal ComPort As String, _
                   Optional ByVal baud As Integer = 9600)
        Port = New SerialPort(ComPort, baud, Parity.None, 8, StopBits.One)

        With Port 'note no event handler
            .Handshake = Handshake.None
            .WriteTimeout = 200
            .ReadTimeout = 200
            .Open()
        End With
        InputString = String.Empty
        'need to change if not 9600
        If (baud <> _DefaultBaud) Then '9600 is default baud rate of ESP8266 firmware (0.9.2.2)
            _Baud = baud
        End If
    End Sub

Not VS 2013, but Using C# 2010 Express, MF4.2 and pushing the button on a Plus 2, yields nearly instantaneous debug output and led blink.

This has been frustrating for me also. Maybe it is both an IE11 and a Forum problem. If I login with Chrome, pasting this this message from Notepad into a  Reply box works just fine.

Mine has sat unused in its box since I excitedly bought one when it first came out. I expect it to stay there.

What about DynDNS,

I haven't used it for a while, but I set it up for a Netduino Plus 1. It's fiddly to get going from behind your router unless you have a smartphone (or use a neighbor's network). Most consumer routers do not have NAT loopback so testing needs to be done from a network external to your local network. Or, in my case, I used a spare router running DD-WRT with NAT loopback for local testing. DynDNS is no longer free, but there are other services.

I don't see that this poses a greater security risk than other traffic coming in through your ISP.

As someone obviously familiar with 3D printing, what do you think of the Da Vinci 1.0 3D Printer?

http://www.amazon.co...bs_6066127011_1

Yes, there is a reason. When the light shines just right you can see the surface roughness. The Da Vinci business model has also received a lot of criticism for the chipped, proprietary filament cartridge. I wish I could afford a Form1 printer. The Da Vinci is cheap enough to play with, but I think I would be disappointed with its results. Thanks for the information about your service.

I recall that Chris recommended a 2GB kingston from Amazon,

I resorted to 4.1 firmware and do not encounter this issue. Both TinyCLR and RESET are working.

 

After looking through the posts here, I see that the 4.2.0.0 firmware is not available. Does anyone have a copy of it that I can test?

Here is the link for Mini firmware 4.2.0.1, both RS232 and TTL

I don't think the Spark Core is Micro Framework compatible. You may have a bit of trouble connecting the hardware to a Netduino Plus 2. Maybe you could talk to it over the serial interface. Or perhaps, give your Netduino a wireless interface with an ethernet to wireless adapter ,

http://forums.netdui...-a-pc-wireless/

I bought a Spark Core and it looks to be a nice companion to provide WiFi capability for a Mini or a Netduino 1 or 2 by talking over the serial port as EnergySmithe noted. There are two serial ports, serial and serial1. The former is the regular Arduino debug port to be used with a serial terminal and the latter would be used to talk to a Netduino. The IDE is cloud based with the same buttons as the Arduino IDE, verify, flash ... They also have an Android App to work with the pins and configure the core for your network. I found the following sample code for a webserver and it works like a charm. The only problem I see with it vs Netduino is shifting gears to program an Arduino.

TCPClient webClient;
TCPServer webServer = TCPServer(80);
char myIpAddress[24];
int LED = D7;

void setup() {
    pinMode(D7,OUTPUT);         // Turn on the D7 led so we know it's time
    digitalWrite(D7,HIGH);      // to open the Serial Terminal.
    
    Serial.begin(9600);

  // Now it's ok to open your serial terminal software, and connect to the
  // available COM port.  The following line effectively pauses your
  // application waiting for a character to be received from the serial
  // terminal.  While it's waiting it processes the background tasks to
  // keep your Core connected to the Cloud.  Press ENTER in your 
  // serial terminal to start your application.
  while(!Serial.available()) SPARK_WLAN_Loop();
  
    Spark.variable("ipAddress", myIpAddress, STRING);
    IPAddress myIp = Network.localIP();
    sprintf(myIpAddress, "%d.%d.%d.%d", myIp[0], myIp[1], myIp[2], myIp[3]);
    
    Serial.print("Spark Core connected to IP: ");
    Serial.println(myIp);
    digitalWrite(D7,LOW); // Turn off the D7 led ... your serial is serializing!
    
    webServer.begin();
}

void loop() {
    if (webClient.connected() && webClient.available()) {
        serveWebpage();
    }
    else {
        webClient = webServer.available();
    }
}

void serveWebpage() {
    //TODO: read in the request to see what page they want:
    //TODO: retrieve larger content from flash?

    webClient.println("<html>Hello I'm serving a webpage!</html>\n\n");
    webClient.flush();
    webClient.stop();
    delay(100);
}

I didn't run it for this post because my Mini is in storage. I lost interest in this because I found for my purposes it was easier to just convert the data type to a string and then convert the string to bytes and then reverse this to go back to the data type (not too efficient, but it works)

Here is a nice automatic chicken door project from the UK,

http://www.picaxefor...ic-Chicken-Door

The Ciseco XRF has a 1km max range with the supplied whip antenna (300m with chip antenna). Other models with chip antenna are of the order of 100m (max). Cheap 433 MHz modules typically have 20-100m range (mostly toward the lower end) depending upon the power, antenna and obstructions.

Reading toward the bottom of the page, that Amazon combo has Specifications:
Transfers distance: 80m (100-200m to the max for open spaces)
Receiving distance: 200m (100-200m to the max for open spaces)
and also, the battery probably costs more than the combo.

Important Note: The remote control does not include battery because of the strict customs inspection. Please prepare a "23A 12V" battery for it. We appreciate your understanding and support. 

Edit: While looking at that page, I spotted another remote control (claims 100m),
