» What if the signal lines are very long? JeeLabs

» What if the signal lines are very long? JeeLabs | Arduino, Netduino, Rasperry Pi! | Scoop.it

This question came from figuring out how to drive an SPI chip over a few meters distance. Normally, you’re not supposed to do that: I2C and SPI in particular are designed for use on a PCB, i.e. distances in the order of dozens of centimeters at best. Fortunately, in this case speed was not an issue, so what if we simply take the clock signal way down, to say 10 KHz (50 µs on + 50 µs off). Can we create a solid SPI setup across a few meters of wiring?

» Speedy Raspberry JeeLabs | Arduino, Netduino, Rasperry Pi! | Scoop.it

The Raspberry Pi is an amazing little board, with an amazing amount of power and functionality at an incredible price – it’s probably fair to say that our technology geek’s world will never be the same again, now that we have the RPi.

But it’s no speed monster…

Sometimes during development, it really gets in the way – especially when you’re used to working on a modern fast laptop, which is some 20 times faster (and that’s per-core).

So I decided to overclock one of my RPi’s, and see what it does. Overclocking in Raspbian is trivial with the standard raspi-config utility:

RESTful web endpoints on Netduino Plus

RESTful web endpoints on Netduino Plus | Arduino, Netduino, Rasperry Pi! | Scoop.it

I have a Netduino plus at home and I love it. Not only can you use C# to write for it, but you get full visual studio integration including live breakpoints! I got the Netduino plus over the Netduino because the Netduino plus has a built in ethernet jack and ethernet stack support. This way I could access my microcontroller over the web if I wanted to (and who wouldn’t?).

» LCD screen for the RPi JeeLabs | Arduino, Netduino, Rasperry Pi! | Scoop.it

For a little side-project I’m involved in (more on that in a future post), I wanted to try adding a little LCD screen with touch sensor to a Linux setup. Found this one at iTead.  There’s a little ribbon cable and adapter (just re-wiring) available for it, which allows plugging this thing into a Raspberry Pi. The nice thing about this screen, apart from being 320×240 pixels and 16-bit color TFT, is its physical size – just right for a stacked setup

If you're anything like me, you've wondered what happens in your garden while you're not watching. I wanted to know when birds are most active – are they busier in the evening or early morning? Thanks to the latest technology, now with a couple of taps of my smartphone I can monitor the bird activity in my garden from anywhere in the world.

EMF Detector - Aaron ALAI

EMF Detector - Aaron ALAI | Arduino, Netduino, Rasperry Pi! | Scoop.it
I changed the code a bit, added an LCD, and increased the antenna size of my old EMF detector. It's sensitive enough to detect the different speed settings in my ceiling fan. The numbers are unitless, thus are are only relative to themselves. I hope one of these days I can get my hands on a good digital EMF detector so I can calibrate mine and make something more useful.  I'll be posting more code and such for the project later this week.

Interested in adding some NFC fun and excitement to your Raspberry Pi? You're in luck! 

One of the big advantages of Linux is that it includes a large number of stacks that have been developed by the open source community, and you get to take advantage of all that hard work simply by using or installing the right library. 

NFC is no exception here, with libnfc having been around for a quite some time -- in fact, it's the original reason the NFC Breakout was developed!
