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.

FEZ Panda & PS3 Controller

August 5th, 2011 14 comments

NB: The newest source code can now be found at github.

As Thomas origanally posted, the FEZ Panda can actually be used as a USB-Host: Fez Panda And USB Host. I have for long time wanted to use my PS3 DualShock 3 controllers for something useful (besides playing Playstation of course), therefore I thought it would be interesting to connect it to the FEZ Panda.

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.

Guide: How to use an Arduino as an In System Programmer (ISP)

June 29th, 2011 No comments

I recently bought the “Graphic LCD Serial Backpack” from Sparkfun. When reading the comments for the product. I discovered that a user named “SummoningDark”, had made a new improved firmware. A lot of people asked Sparkfun to change the official firmware with the new one, so i decided to check it out. The problem were that I do not own a programmer, so at first I thought that I had to buy one. But after some googling I found out that the Arduino could actually be used as an In System Programmer (ISP).
After a lot of work I finally got it working and it has really improved the perfomance of the screen. The speed is much higher (SummoningDark says 10 times) and there are no more bugs (with the old firmware the screen would suddenly write the text or a line a odd place).

I will now try to explain as best as I can, how to upload the new firmware.

NB: You can also use this guide if you need a different bootloader or another hex file on any AVR. This is just meant as an example.

NXT Motor Shield

June 29th, 2011 12 comments

Update
The NXT Shield is for sale in our shop: http://shop.tkjelectronics.dk/product_info.php?products_id=29. A easy to use library is also provided: https://github.com/TKJElectronics/NXTShield.
Three examples that demonstrates reading the encoders, turning the motors and using the ultrasonic sensor is found in the library as well: https://github.com/TKJElectronics/NXTShield/tree/master/examples.

More pictures of the NXT Shield can be found at the following blog post: http://blog.tkjelectronics.dk/2012/04/nxt-shield-library/.

The shield mounted on a Arduino

Hallo everybody

I recently made a NXT motor shield for my arduino. It can control two NXT motors and also read the onboard encoders. In true Arduino spirit I decided to share it with the rest of the community. But first i will talk about how everything works, and then show the finished shield including a short video demonstration.
