BeagleBone

November 29th, 2011 2 comments

Edit: The BeagleBone is now available for around $89 or ?79 – check out the distributor list at http://www.beagleboard.org/buy

BeagleBoard has recently announced an upcoming product in cooperation with Texas Instruments, which hopefully is going to help both of them to become a bigger part (and share) of the embedded hobby world, which has become pretty big recently and is currently led by the Arduino.

Their new upcoming product is called the BeagleBone

Arduino Due – what about it?

November 28th, 2011 2 comments

Some of you might have noticed the new upcoming product in the Arduino series, the Arduino Due. The Arduino Due is going to be the first Arduino with a processor not being an AVR.

Arduino Due - ARM based Arduino


The Arduino Due is going to contain an ARM Cortex-M3 processor from Atmel, the SAM3U, running at 96MHz. This processor has got a lot more Flash and SRAM than the original Arduino boards, and includes 5 SPI buses, 2 I2C interfaces, 5 UARTs, 16 Analog inputs and a whole bunch of Digital I/Os.
With the processing power of this new board and the big community around the Arduino family, we are going to see much bigger and more advanced projects in the future.

Finally Arduino has realised the need for a more powerfull but easy development board for the market. They have realised that the ARM-family is the way to go in the embedded world, and I am very satisfied with the choice of an Cortex-M3 processor, which is relatively low cost, has a fair amount of processing power, Flash and SRAM and of course also a lot of usefull periphirals.

Their plan is to have this board ready for the market by the end of 2011. We are definitely looking forward to test and review this!

EZ430-Chronos Unboxing and Demonstration

October 3rd, 2011 3 comments

About a month ago Texas Instruments started their so called TI Deals – “A cool new way to get discounted tools and kits from Texas Instruments”
The service is an advertising stunt by Texas Instruments which lowers the price of some of their development tools in a specific period.

The first product to be lowered in price were their EZ430-Chronos watch. A watch with their CC430 MCU inside with wireless connectivity.

The regular price for the watch was $49.00, though as it being the first product in their new “TI Deals”, the product were sold for $24.50 – 50% off! Including free shipping.
An extremely cheap price for a good looking watch (maybe a bit big) with developer possibilities. So I decided to get myself one – and luckily for me I ordered one in time, as they went out of stock pretty fast!

Arduino RGB LED Controller

August 23rd, 2011 54 comments

When reorganizing our stock I found a whole bunch of diffused RGB LEDs (>100pcs) so I thought I would make something cool with them. Maybe some kind of individual controllable christmas light or some lights you could use for showcases etc.

RGB LEDs


So I decided once again to make a project using the Arduino Duemilanove, as it is so quick and easy to get a prototype working.
After some brainstorming, thinking about how I should do the PWM multiplexing, I designed a circuit capable of driving 8 individual RGB LEDs using 11 pins. The project would be easily expandable and would only cost 1 extra pin for each extra RGB LED.

PIC-based wateralarm with SMS function

July 18th, 2011 11 comments

Some of you fellow readers and subscribers may have noticed the video on Youtube of our PIC-based SMS Wateralarm. I went on vacation and forgot everything about it, especially I forgot to write about it in here – so I think it’s time.

PIC-based SMS Wateralarm


The project is a school project about Water, in the class called “Technology”. We discovered the growing problem about flooding of houses near rivers and lakes, and thought it would be a brilliant idea to invent a system that could alarm the owners by an SMS, if flooding should occour.
