#23681 Resistors
Posted by OppaErich on 02 February 2012 - 02:23 PM in General Discussion
I was thinking camera when I wrote 'nice project idea' and that would be too much for me. But it is possible, someone at the Parallax forums built a Guitar Hero playing device. This thing is analyzing the video signal.
I didn't know that there are color sensors, that may be not too hard.
Edit:
Ooooh, a buddy of mine does IPhone apps for a living, I've posted him about it.I thought about writing a smart phone app that would take a picture of a resistor and tell you the value, but I just never did.

#23559 TOC for "Getting Started with Netduino" yet?
Posted by OppaErich on 31 January 2012 - 09:18 AM in General Discussion
If you ever make it to western Germany, The Netherlands or Belgium give me a shout and I'll be there.I'd be honored to sign your copy. Will you be at MakerFaire?
Nice to hear the book is nearly ready. Amazon.de is trying to convince me to cancel my order once a quarter. "we can not give you a delivery date for your order - are you sure you still want this ?".
#23311 How to control 220V stuff
Posted by OppaErich on 25 January 2012 - 05:38 PM in Netduino 2 (and Netduino 1)
Don't burn down your nice little country.I'll look for a nice relay in the local hardware store.
#22931 New to Visual Studio and C#
Posted by OppaErich on 18 January 2012 - 11:32 AM in Visual Studio
It's not that I really like C, I have just gone a little bit further than Hello World in C already. With C# only Console.WriteLine, well Mono actually... and haven't tried VB yet.You could also try to use Visual Basic by the way, also works on a Netduino
And if you really like C or C++
"Scary" was referring to the (novel-like) size of the code. Of course does everything you don't know look strange.
#22928 New to Visual Studio and C#
Posted by OppaErich on 18 January 2012 - 10:15 AM in Visual Studio
Scary, isn't it ? I own a netduino for about a year but haven't done anything with it yet. I don't know C# and looking at code snippets posted here, I'm always wondering: "Is this code or a novel ?" I'm digging into msp430s now, that's plain C. Good luck.and looked at a bit of code...
#22920 Digital Output readings from DS18B20

#22058 DS18B20 wiring help
Posted by OppaErich on 24 December 2011 - 08:26 PM in Beta Firmware and Drivers
You DO need the resistor to tie the com line high, otherwise it would be floating = noise sensitive. It may work without it mos of the time but that's just luck.4.7kohm resistor you don't need to use.
#16036 Sweet deal for capacitive touch interface
Posted by OppaErich on 29 July 2011 - 08:47 AM in General Discussion
TI provides a 'capacitive touch library', you may check that (I did not yet).Before I embark on trying to hack something up to read from this device, I figured I would check if anyone else has a driver written?

Is it just me or did I miss a thing ? The price is $10.

#15324 Newbie ds18b20 questions
Posted by OppaErich on 11 July 2011 - 01:59 PM in Netduino 2 (and Netduino 1)
The sensor is called once every few seconds, I've added this to the Arduino 16x2 LCD demo sketch. Oh, it's 'range', I've read 'rate' first. Well, I did nothing range related, so I don't know. What do you mean with 'reference' ? An cheap IN/OUT thermometer and my body. It's 25°C in my room according to my thermometer and the DS18B20 shows almost 28°C, at 28°C I would start to sweat even in 'idle' mode.I don't think they can be calibrated, IMHO you'd need to implement it in software. Just out of curiosity, how often do you perform the temperature conversion? At what range? What is your reference?
Supply Voltage doesn't matter (5V / 3V3). I've used a 4k7 resistor and it's powered - not parasitic.

...
, but keep in mind the sensor has ±0.5 ºC accuracy (from -10 ºC to 85 ºC). For more detailed information, please have a look at the device datasheet.
Well, they pretend to have. Mine here is more than 2°C off. Does anyone know a way to calibrate them ?

#12754 RFID Reader

You remember her songs ?In the '80 there was a voluptuous girl named Samantha Fox: her biggest pop-hit was "Nothing gonna stop me now"...
Good job ! Thank you, one less to worry about
