I'm not sure if this would work submerged. It says water resistant not waterproof.

P.S.
We could add an "internal 3.3V analog reference" option in a future board revision. Would that be a valuable feature for everyone here? We'd make it optional and selectable in code.
Chris
It seems like this would be useful. Especially so for people who are "porting" Arduino projects.

Selectable in code would be cool.yes please
I also had a question about pull-up resistors. In wiring my I2C clock chip, I used external pull-up resistors. Is it possible to use the internal pull-up for this? I'm not really using the pins as input per-se, but if I plug in an I2C device, it likely needs pull-up resistors. Yes, I'm a hardware newbie... I'll bet it shows.

Another quick tip: There's a static Encoding class that you can use instead of "newing" one up for StrToByteArray
Encoding.UTF8.GetBytes(s)will do the trick and save you a little bit in terms of memory allocations.
#318 SerialPort class?

Hello all,
I have included a reference to System.IO and a using statement for System.IO.Ports, but the SerialPort class doesn't show up. What am I missing? I'm sure it's probably something simple that I'm overlooking.
Thanks!

Sorry for the traffic, but I just found it. Microsoft.SPOT.Hardware.SerialPort in case anyone else is looking.

#1735 Serialization

Netduino 2 (and Netduino 1)
I don't think Serialization is available on any of the .net platforms (Netduino or Fez). Besides, for a microcontroller serialization is SLOW.
Slow depends on the application don't you think? For my application it's okay it it's a bit slow. I need to deserialize once at startup and then the intervals between serialization are pretty long - on the order of minutes to hours.
In any case, if people are using the emulator, be aware that Reflection.Serialize and Reflection.Deserialize work fine, but they appear not to be in the Netduino firmware. This is not a major problem for me since I just implemented my own code for what I need, but it's good to know what's there and what's not.

Reflection.Serialize/Deserialize seems to work fine in the emulator, but not on the actual hardware. Is it not implemented in the release? Is it planned?
Thanks,
Stacy

And of course, if you're using the DS1307, check out my post w/code here: DS1307 Real Time Clock.
This clock is pretty inexpensive and works well. I'm sure that there are better ones out there with alarms, etc.

Check out this thread: Serial Port Class. I had the same problem. You need to add a referennce to the Microsoft.SPOT.Hardware.SerialPort assembly. It has part of the System.IO.Ports namespace in it.
Let me know if you need any more help.

While you're on the topic of soldering, maybe a thread or blog post on techniques would be cool. There are a few "how-to's" out there, but they miss a few things that scare beginners. For example, I sometimes see chips soldered directly to a board, and other times I see them in the little chip holders. (Hmm. Chip DIP jokes come to mind). How do I know when to do which? I'm learning a lot of this as I go, but could certainly benefit from the wisdom of others.

Thanks. That's good to know. At this point, my hardware skills are minimal. The idea of surface mount soldering seems a bit beyond me. I have basic soldering skills and will be trying my hand at something that's more advanced - for me anyway - within the next few days.

I've been running into the same issue every once in a while. I've been able to get around it by going through the erase process as well. It seems like there's some timing going on there too. Sometimes it takes 2-3 tries to get through the erase. I'll try to keep track of my steps to see if I can make the problem repeat and maybe gain some insight into the issue.

#2150 MP3 Shield

The first shield also has a built in SD card slot. By the time you add that, the prices might be closer.
This is one of those projects that will have to wait for a while anyway. I need to get another netduino and some time. Gotta finish the current project first.

.NET Micro Framework supports FAT file system so I believe you only need a shield with and an SD card card socket. Or use other net micro framework device that has SD/microSD card socket. There are several out in the market.
Yes, I understand that. That's why I thought the first shield would be good since it's MP3 and has SD built in. It seems that assembling the features of the first shield from separate components would come out to about the same cost, don't you think? Of course, it would be fantastic to do it for less money!

Netduino community (netduiners?),
Here's another shield that would be interesting to test: MP3 Shield for Arduino. I've seen some posts out there for making a similar device sans-shield for around $30. I'll have to investigate that. It would be interesting to use something like this as a source device for my whole house audio system.

#1654 Motor Control in an Airsoft gun

Yes, those ideas make more sense than the switch. I'll take another look at the lever in the gun to see what we can do. This is fantastic help. Thanks very much!
The motor is this one: ICS Turbo-3000. I haven't found an actual spec sheet yet. We just need to control on/off really.
I also ran across this: Using a transistor to control high current loads with an Arduino which seems like it would work.
Thanks again!

Hello all,
I'm pretty new to electronics and still developing basic design skills (I'm a software person). I'm hoping someone can give me some simple guidance.
My son and one of his friends are modifying an electric airsoft gun so that the firing mechanism is controlled by a microcontroller. They want to be able to have the trigger be a button press that the microcontroller reads and depending on the programming will activate the motor in the airsoft gun. There's a little lever in the gun that moves each time the gun is fired. By adding another switch that this lever will hit, we can count how many times the gun has fired. The microcontroller can then be programmed to give us variable bursts when firing.
My questions are:
I realize that being new to this, my questions may not all be well-formed, but I'm hoping this will get us moving in the right direction.
Thanks,
Stacy

My questions are:
- Does this seem reasonable so far?
- What's the best way to control the motor?
- Should we use a MOSFET or a solid state relay? What are the practical differences in the two?
- Anyone care to venture a circuit diagram that will help us?
I realize that being new to this, my questions may not all be well-formed, but I'm hoping this will get us moving in the right direction.

Thanks! I'll check out those links. I'll take all the knowledge I can get on this one.
If anyone else has thoughts, please chime in. I'm going to try to get some photos of the mechanism in the airsoft gun. It's all very heavy and mechanical. I'm also worried about how we're thinking of using a moving lever to tap a switch that will count shots. If we can get that and the motor control nailed, then the rest is just software.

Okay. I'm starting to understand a bit more. I'll ask my son and his friend to look on the motor itself for any additional specs, and I'll look at the types of transistors you mentioned. I appreciate the great explanations! It makes this fun for novices like me when we get such great help.
Thanks!
