Arduino Indoor Thermometer

I wanted to do a simple project for my newly acquired 16×2 LCD display, and thought I should do an indoor thermometer. I searched around a bit online but couldn’t find exactly what i wanted to do, most projects where indoor/outdoor. I did however find this great tutorial here on hooking up the 16×2 LCD with 2 pots.

I added my LM335z temperature sensor, hooked up my arduino, made a little sketch to output the temp to the serial monitor. It was 3 degrees off and that could have easily been fixed with a another pot however i only have 2 and used them for the LCD display. Here is a diagram i made with fritzing.

And here is a very poor photo of the finished project.

7 segment display schematics for T0D323BMRL / D12C04186R

The 7 segment display i used in my previous post has the part number T0D323BMRL and D12C04186R. I googled these numbers and came up with nothing, even at websites devoted to schematics and part numbers. Therefore i had to find out the pins myself, which wasn’t that hard but i thought i would post the info here in case someone else needs it as it is not a common diagram.

Update

So its been about a month since my last post. I’ve grown bored with Python and development in general, however that does not mean I’ve been unproductive.

The micro controller Arduino has been my new obsession. Namely salvaging old lcd displays, and segment displays, and then getting them to work with Arduino. There is minor programming involved but not nearly as much as before so the small break is nice.

Pictured below is a 2 digit 7 segment display that i salvaged from an old radio shack cordless telephone (cat 43-3880). It came from the phone base, not the handset. It only has 9 pins, pin 2 was never installed and i assume it controls the decimal point seeing as that was the only segment i was unable to light up. Its common anode which are located on pin 5 and 10.

DDR 5th Mix Backgrounds

Here are the backgrounds for DDR 5th Mix for Playstation. Only 47 songs in the 5th Mix so only 47 backgrounds. I also noticed when doing these that the 5th mix has less play modes available but has a nice gallery of images that can be unlocked.

I did not mention this before but all of the backgrounds for the playstation DDR games are 320 x 240. I mention this because i am aware that some of the backgrounds in my images are white at either the top, bottom or sides making it hard to distinguish  the edge of the image. Having the dimensions should eliminate any questions of the image’s borders.  Enjoy!

Arcana (SNES) Text Dump

 

Attached to this post is an almost complete Text Dump from the Super Nintendo game Arcana.  It currently has ALL dialogue, items, spells, locations and some other misc stuff. Left to be done is item, and spell descriptions. Also it should be noted that i started this in Notepad ++ but for whatever reason wordpress will not let me upload a .txt file so i had to convert it to a .pdf so the formatting is a kinda off but still readable.

For the moment there are alot of entries into the Misc. section and i plan on cleaning this section up after all the text is dumped from the rom. After the text dump is completed i also plan on making a python program that will change certain text to whatever the end user desires, within the limitation of what the rom is capable of displaying.

Hopefully someone out there will find this useful.

Steg Img update

Before I release Steg Img I would like to go over some basic steganography techniques used in the program. At present       Steg Img does 3 different scans. The first scan will test for certain text within the file. For instance if you take any image and open it with a text editor you will see a bunch of characters that make no sense what so ever. However text can be hidden within all the non sense characters.

The second scan will see if the image file contains another file within it. To be more specific using a command prompt you can combine a text file, mp3 file, and many others with the image file. This in no way changes the image file and the image is still able to be viewed with your favorite image viewing software.

The last scan is a bit more complicated. To explain look at the picture below

.stegtest1

A pixel is made up of red, blue, and green, or RGB value. The value of either the red, blue, or green can be between 0-255. Download the image and open it in your favorite image manipulation program, and zoom in as far as possible. Next we will be converting the pixels to letters. Use a color picker and choose the first blue pixel of the blue strip.  Its R,G,B value is 0,0,112 meaning the pixel has 0 red, 0 green, and 112 blue.

Now if we head over to asciitable.com we can convert the pixels to letters. We can see by using the table that the decimal 112 is = p. Next we will check the second pixel. As you can see it has a value of 0,0,97 which is = a. The last 2 pixels are 0,0,115 which is the letter s.

The reason I used the word “pass” is because if the word “password” is located within the image it would’nt be necessary to search for the whole word since pass is inside password. The algorithm Steg Img currently uses only looks for the word “pass”.  Im sure by now you can guess what the other 2 pixel strips say. Keep in mind this is a very basic method and is predicated on having 0 in the other two RGB values.

Hopefully with the next  Steg Img update i will have something worth releasing.
