Hi All, I thought I'd share a video of what is included in the AREXX Robot Arm kit: 28-13530 - Buy AREXX 28-13530 Online at Newark element14There is also a "pro" version available, which is bigger and is fully made of metal, where this mini vers...
A while ago I received a Raspberry Pi 2 model B - the new and improved faster version of the Raspberry Pi.I already had a Raspberry Pi B+, so it was neat to be able to compare the two. UnboxingHere are some first impression pictures:The Pi2 (on ...
I've been working on a data logging system for my greenhouse - basically just a way of tracking soil moisture, sunlight, rain barrel water level, and of course temperature inside and outside of the greenhouse. I built most of it for Arduino, as ...
For the second circuit in my quest to compare Arduino to FRDM/mbed, I decided to try CIRC-04 (Servo) of the Oomlout tutorial: http://www.oomlout.com/oom.php/products/ardx/circ-04 This one is also quite easy, as it's been done before!I was able t...
For the longest time, Arduino has been my favourite development environment simply because it is so easy to use. Now, mbed.org and the FRDM-KL25z board are looking like they might become my new favourite. The reason for that is based on my ...
Unfortunately, the Freescale Freedom FRDM-KL25z does not come with headers installed, or even included.This set me back a few weeks having to wait for some headers to arrive in the mail - although I admit that as a good electronics nerd I should have...
A few weeks ago Pat Kelly (one of the good folks of element14) told me about the new Freescale boards that use mbed.org for easy and quick firmware building. Easy and quick, you say? That sounds perfect for me, the hobbyist with very little spare tim...
I keep mentioning how I love the simplicity of the Arduino platform, and the endless libraries it includes to support all kinds of hobby projects. I don't know if I've mentioned how I cry a little every time I see an incredible hardware platform with...
I spent some time today checking out the code for the webserver demo and the camera demo. Wow. This is sooo not the quick and easy project I thought it would be!The code consists of some heavy duty C, and there's lots of it. It's nicely org...
Finally, some time! I was able to get the webserver code compiling by signing up for the IAR time-limited license. I have much better uses for the $300/month they wanted to charge me for a regular license. And then I didn't have time to wor...
It's a sad day today. I thought I'd check out the web server example, as this is what I wanted to base my webcam on. But alas, it seems I've run into the code size limit for the free version of IAR Embedded Workbench: "Error[Li016]: size limit e...
Hi All, I received a null modem adapter in the mail today - coupled to my serial-to-USB converter it works perfectly!I know, I know, you're already missing all the little wires I had rigged up earlier I also thought I'd test a few more sam...
I had this nagging feeling that somewhere in amongst all of my boxes of bits and pieces there would be something serial cable related. Well, it turns out that in one forgotten box in one forgotten cupboard I did have exactly what I needed - an o...
This is really neat! The samples are really well done and compile easily, and that makes me happy! I followed the user manual that came with the add-on boards: "DM-STF4BB User Manual". The first thing I did was to hook up the display....
Oops, it seems that I have left all of my serial cables back in the 90's. To do many of the provided samples I'll need a db9 F-F null modem cable.Aah that brings back memories I have a serial (M) to USB converter, so at least I've got it t...
After adding a second virtual harddisk to my VirtualBox WinXP VM, I was finally able to install IAR workbench for ARM (aka EWARM). Hooray!! After that, it was easy to just follow the rest of the steps in the Getting Started document to rebuild a...
I'm missing my Arduino environment already!Setting up the Arduino environment on Mac is a matter of a few minutes and that's it - you're up and running.This board, unfortunately, requires me to set up a virtual machine to run Windows, which in itself...
Ok, I'll admit it - just plugging in this board and watching the multi-coloured LEDs light up is fun but doesn't keep me entertained for very long. So the next step is to set up the development environment so I can program it myself. The pa...
The first thing I did in trying out this board was to plug it in to my computer, which requires a USB cable with a mini-B end on it.The board doesn't come with it, but that's more than fine with me, as I seem to have been accumulating these cords for...
I was recently blessed to receive some very cool new toys from the good folks at element14! This time they were kind enough to send me an STM32F4-Discovery microcontroller board complete with this expansion kit that includes a camera, touchscree...
So I gave up on the temperature monitoring for the time being, as watering it became more important. With us wanting to take a few vacation days, I figured I should get this going so that we don't need someone to constantly water it. I have...
neilk gave me the idea of logging greenhouse temperature data into a spreadsheet, so I did a little more investigating into how this would work with Gobetwino. I have a little greenhouse not too far from the house, so I thought this might be a neat t...
I was watching a conversation on the forum about questions regarding Arduino, which involved connecting Arduino to a Windows-based program named "Gobetwino", and it caught my interest. In a nutshell, Gobetwino is a program that runs on your Wind...
