Hello all,

Here is a new type of programming language that is meant to get non-coders coding... Its called Scidgets and its a visual style of programming for microcontrollers.

Hello All,

I have been looking at face recognition apps for a long while now and have not found any good ones out there. There is only one that catches my interest and it looks to be working properly and actually recognizes and matches faces between 2 different photos.
What it does is that it recognizes the faces, then detects the facial features and then decides if they are a good match or not.
This can be very useful for for finding person of interest for law enforcement or photographers in general.
Here is the link to the AppStore: https://itunes.apple.com/en/app/id1120263989

Hello All, 

Here is a video update to the amazing capacity and capability that the BrainCard has. 
Its truly amazing and at the same time hurtful that this technology has been around for 30 years and only surfacing now...

Hello All, 

I am not sure if anyone here knows about the "Brain Chip" by IBM which has been around for 30 years. 
This chip acts as a brain and it has "Neurons" inside which makes it very attractive. It removes the bottleneck of processor-memory communication in conventional microprocessors. Every neuron has a processor and a little memory. 
The beauty of the brain chip is that you DO NOT program it. You TEACH it! Basically you teach it what specific pattern to recognize in ANY data type and it will raise a flag when it sees that pattern again. Oh and did I mention it can do this in real time. It find a pattern in any data set in as little as 500 ns (Nano Seconds)! 
The applications of this is endless. Think about medical, security, data analysis, etc... 
I highly recommend you to watch this video: https://www.youtube.com/watch?v=7DI48HMKKo8
And here is their indeigogo campaign: https://www.indiegogo.com/projects/the-braincard-powered-by-a-neural-network-chip

Here is their plan: They want to make everything about this chip OpenSource and get it in the hands of the maker community, YOU! Now, if you come up with an product or application that uses the power of the BrainCard, then they will help you to manufacture and take your product to the market. 
You can make a visual recognition system that open the door for your cat. 
You can make a waveform recognition system for ECG or EEG. 

For the Arduino Community they provide an API that you can interface the BrainCard easily with Arduino: http://neuromorthings.com/tech-specs/

For those interested on the more technical side of things: http://neuromorthings.com/files/CM1K_Presentation.pdf

This is only the start. Who knows what is the future of this technology!

Hello All, 

Here is my first attempt to design a build a laser cut case for Arduino Mega and Uno. 
I build it as a protection for the delicate Arduino and so that you can mount shields right onto the case. You can see the pins are visible. 
Its made out of 3 mm acrylic sheet. 
Enjoy!

Hello All, 

For those who require more power and connectivity out of their projects, like connecting to internet, your wishes has come true... 
Texas Instruments has recently created CC3200 Launchpad which has WiFi connectivity and an ARM Cortex M4 all on one chip... And its 80 MHz which is much more speed than the Arduino counterparts. Also its only $30!!!

More importantly, there is Energia IDE which is very much familiar looking to Arduino IDE. This means very easy transition for Arduino community.

Whats more is that there is already a WiFi library built in Energia IDE specially for the CC3200 Launchpad. 

Thanks,

Hello All, 
Its been a while since I posted a project. 
This time the project is really cool... 

Say hello to my Remote Controlled Mini Mars Rover... 

Project Description: 
As the name indicates, this is a remote controlled robot.
The remote control has a joy stick (2 potentiometers in x and y direction) and a tactile switch. 
The Rover is 4 wheel drive which makes it very effective on rough terrain. Each wheel is attached to geared continuous rotation servos which makes it very powerful. The left side wheels are driven together and so is the right side. The driver for motors is based on a single L293D chip. The motors each use about 40mA of current, so a single L293D is more than enough. I am using the Adafruit Motor Shield. 
The Pan and Tilt system is based on two 180 degree rotation servo motors. This is meant to have a wireless camera attached to it. 

How it works: 
The joystick is used to drive the Rover. When the tactile switch is pressed, the same joystick is used to drive the Pan and Tilt system. 
The wireless communication is established using 433MHz transmitter and receiver modules (very cheap). 

Thanks,

Hello All, 

This post is dedicated to Luciano Zu and his project. Ardulink, as its name signifies, is Java solution for linking multiple arduino boards. Please refer to his website for more information: http://www.ardulink.org/

Thank you,

Hello All, 
Have ever written some code for arduino and every thing is ok on the computer end (it compiles and you get confirmation of upload to arduino), but when you try to run the code on arduino, it does not do anything? 
This might be because of couple of reasons: 
[for your reference, I am using the Arduino Mega 2560] 
1) Your code is too long: meaning you have too many variables (such as arrays) that take up program memory.
2) Your code uses a lot of processing power: you are using internal interrupts and a lot of computations at the same time that the processor does not have enough time to finish. Doing floating point calculation is the culprit most of the time. 
3) I am sure there are more reasons out there which I have yet to discover... 
The most important sign to let you know you have one of the above problems is instead of steady light on 'L' you will get blinking light. If your code is not meant to blink the LED and it does blink, then you know you are in trouble. 
I had to find this out the hard way. 

The solution to this more processing power and more program memory --> Intel Galileo... 
http://www.intel.com/content/www/us/en/do-it-yourself/galileo-maker-quark-board.html

This beauty has a 400MHz 32 bit Intel Pentium ISA processor and comes with all kinds of goodies. Here is a link to the datasheet: https://communities.intel.com/servlet/JiveServlet/previewBody/21835-102-4-25148/Galileo_Datasheet_329681_003.pdf

So now, the big and processing power consuming code will run like a charm, and a lot more room to spare. 
Thanks to official Arduino people, you can upload the same code you written for Arduino Mega 2560, to this beauty. 
The possibilities are endless with this one... 

Thanks,
