What do you think?

I got my Dotklok up and running some days ago, I am really enjoying it on my room.
But I want to do more with it. Too bad right now I don’t have much time to play with electronics and build cool things.

Anyway, today I decided to spend some time learning the Dotklok’s code and add a temperature sensor to it. The result was really cool, and now I am sharing the bit of code I added to the clock.

To make it work in your clock, you must add a new effect called temperature(); in the switch area, then in
time animations, add the code below. And for the hardware, I used a LM35 Temperature Sensor connected in 5V, GND, and AD3, but can use any AD available, just change the code afterwards.

Here is the code, but you can check the RAW file too.

// temperature()
// Temperature Sensor + Clock – by Daniel Spillere Andrade – www.DanielAndrade.net
// Should Change the Temperature Only when minutes change, to prevent floating on temperature

plot(14,9,1);
plot(14,10,1);

// Drawing the ‘C’, it’s ugly I know
for(int i=16;i<19;i++){
for(int j=9;j<14;j++){
if(j==9 || j==13) { plot (i,j,1);}
else { plot(16,j,1); }
}
}

int temppin = 3; // Define LM35 PIN
int tempval; // Temperature Read Variable

tempval = ( 5.0 * analogRead(temppin) * 100.0) / 1024.0; //Makes the first read

/* TIME LOOP */
do{

time_now = RTC.now();

if( ( time_now.minute() != time_prev.minute() ) ){
if( !power_up && midnight_random() ) return;

tempval = 0;
for(int i=0;i< =9;i++){
tempval = tempval + (( 5.0 * analogRead(temppin) * 100.0) / 1024.0); // Reads the Variable and converts to Celsius
delay(100); // tempf = (tempval * 9)/ 5 + 32; to converts to fahrenheit
}
tempval = tempval/10;

}
// Here starts the code.
// Draw Temperature, only when minute changes!

putchar_3x5(5,9,(tempval%100)/10);
putchar_3x5(9,9,tempval%10);

//Draw Time
putchar_3x5(0,2,(time_now.hour()%100)/10);

putchar_3x5(18,2,time_now.second()/10);
putchar_3x5(21,2,time_now.second()%10);

time_prev = time_now;

/* CHECK BUTTONS, return if necessary */
if( change_animation() ) return;

while( PAUSE && b5.isPressed( )); // pause mode for photos

} while(1);

Long ago, I wrote How I Made my HTPC at my place. Time passes and things change. End of year has arrived, Christmas and everything, so I decided to upgrade my system to a more efficient and cheaper one. The new choices were using a NAS (Network Attached Storage) allowing all files can be accessed from any machine connected to the network, in this case I am using Lacie Network Space 2 2TB storage. A Gigabit router TP-LINK , so far I’m very happy with this router, although. A media player WD-PLUS Live that has an embedded Linux and play videos in various formats, even FullHD , and access online content like YouTube and some radios.

Media Center:

I will begin showing every part it:

Lacie Network Space 2 – 2TB

A NAS very powerful, relatively inexpensive and with a storage space for my current needs for backup and media like movies and TV shows.

The NAS has a good web interface, and you can even download torrents while your computer is OFF. It uses only 6W in standby mode and 12W in active mode.

You can manage your files via the Finder (I believe the Nautilus or Windows Explorer as well). Or the way I prefer, via FTP . Testing the speed via FTP I got around 30MB/s, really good for a ARM processor.

There is the possibility of hacking the device and get full SSH access, but as I do everything I need from my Macbook’s terminal or via the WDLIVE’s SSH , there is to change the hardware or the NAS.

Besides being able to access files over the network, there is also the possibility of obtaining your files by USB cable , but you will not have access to all files. When you configure your Lacie , you determine how much space is used as a network storage, and USB storage , which does not make much sense to me, but that can be some limitation on hardware / software.

Another peculiarity of this NAS is an extra USB port, where you can plug a thumb-drive or other storage device and access it from any computer in the house or even the Internet, since the Network Space 2 comes with the option to be accessed from anywhere on the Internet, through services like DYNDNS .

If you’re thinking of buying an external hard drive that don’t need to be small and portable, I find interesting in making some research about the NAS option, which is very good and practical.

Backups, backups, backups … I don’t live without them! You shouldn’t either!
Can not stand the idea of losing all my precious photos, so one of my priorities with a Storage System is the safety of my backups, which are made weekly using the Super Flexible Syncronize software, equivalent to SyncBack on a Windows PC. What I like about this program is the ability to update only what has changed.

WD PLUS LIVE

The WD PLUS LIVE is nothing more than a small computer with an operating system to playback videos and music. He has no storage, so it should you have to plug a thumb-drive, external hard drive on it or connect to the network, which will give access to shared files over the network, in my case, files are stored at the Network Space 2 connected to the router. When I bought the WD, I was impressed with the image quality, and how he can play heavy files without any choke. I watched the Band of Brothers show recently co-directed by Tom Hanks and Steven Spielberg in FULL HD 1920×1080 , where files were like 7GB for episode of 50-60 minutes. I played all over the network, and it worked perfectly.

The Hack:
The WD PLUS LIVE is very powerful, but it can be much more. A boy named B-RAD , has compiled a new firmware for the product by increasing its possibilities infinitely. You can access the media player via SSH and may use it to download files, torrents, unpack large files, FTP server , to access IRC (and stay connected 24 / 7 ) and anything that a computer can do via SSH , so the imagination is the limit!
This new FIRMWARE you find HERE .

Thanks for reading.

I’m planning on releasing all the project as Open Hardware/Source, but due my lack time, it’s not on my website yet!
Would you like to take a look at this project??

Hey, I got so exited about the DotKlok that I decided to build my own! As it’s quite difficult to buy one from here (I live in Florianópolis – Brazil), and to pay U$150 for the Kit wouldn’t work for me… So I want to build a good looking clock for my room, which I only have my computer and mobile as clock.

First of all, I needed to buy the 24×16 Led Display from Sure Electronics, which I found for a good price at eBay (little cheaper then buying from the Website).

I just got back from the gym when the board arrived from the post office, as you can see by my face:

Then I got the PCB from Dorkbotpdx, which came really fast and with really good quality, as you can see in the image below, and the board is dark purple, really cool!!

So here is the clock working:

My next step is to add a LM35 temperature sensor to it and learn the code so I can make my own effects. I will also disable some effects that it’s too hard to read like in more code, not really useful.

If you want to build your own, you should check http://www.technoetc.net/dotklok/ for instructions, code, design and everything else you may need.

Keep posted for my new mods for this amazing clock.
Thanks

This is amazing, perfect for those times when your have to create another board just to hold the atmega µC. I am looking forward to use this tiny board in some project in a near future. Congrats to Varesano for the project.

You can check his project HERE.

DOTKLOK: Game Time from The Latest Artists on Vimeo.

DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations. The passing of time is depicted with numbers and abstract/geometric patterns such as Morse code and minimal analog clock faces, and includes animations inspired by classic video games such as Pong, Tetris, Pacman, and Space Invaders.

You can buy the kit for U$150.00 and it assembled for U$200.00
for me… I think I will build one, hell yeah I’m going to build one, just love it!!!

You can check more information from dotklok’s website.
