Check this simple easy to use tool i just made. Im always using google to convert from 1 unit to another. This helps me out a ton…
Can convert from and to: MM, MIL, CM, INCH

If you think im forgetting something just tell me. Single click on list will copy selected text into the clipboard. Download link coming soon!

AtomNotes V1.2

Ok now with proper file association… well sort of… you have to manually associate the files since im lazy. But after thats its beautiful. Also fixed a saving bug…

AtomNotes V1.2

How to Video:

AtomNotes V1

Ok here is my version 1 of AtomNotes. This is NOT TESTED well but should work heh… requires .NET 4 (using on windows 7 but should be good on others)

AtomNotes V1

Please visitors if you download it and find a bug post a comment. I would love to see what bugs are and try to fix them ūüôā


Ok this is still a work in progress. But so far its awesome! So far you can create new notes, save notes, open notes, change colors and fonts.
The main thing im working on is saving the note color with actual note so you can reopen as it was saved exactly. (fonts are saved)

UPDATE: New Video uploaded.  I changed the above video..

WonderMedia Part 2.

Ok i found some great info on this WonderMedia WM8505 part. Using my awesome google-ing skills i found some great stuff including a Data sheet for the WM8505… On a side note… Still not able to get into original U-Boot.bin ūüė¶

I uploaded it to my site for all:

I havent completely checked out the files yet only the datasheet. So im off to investigate some more ūüėÄ

UPDATE: Looking at the PDF my worst fears have came true. It has a built in LCD controller which means i wont find a ton of info on the LCD. But im sure i can still get some INIT code and Pinouts if i look hard enough ūüôā

Chinese Wonder* (pun)

Ok i have one of those tiny 7 inch laptops which has a ARM and WinCE/Android running on it..

While this is pretty cool to have i have no use for it. Unless i start learning how to program for android. Which i will not even get into. The cool thing i like about this laptop is the 7in LCD and the fact it has a mouse and keyboard built in. I would love to be able to use this for something other than what it has.

This so called PC uses a WM8505 Processor which in it self is quite hard to find good info on..

Here are some specs on my model:

Max Resolution: 800 x 480 px

1 * 3.5mm Microphone
1 * 3.5mm Headphone
1 * SD/MMC card slot

Now for the GOOD the BAD and the UGLY!

The Good… The main board has a UART port on it and i am able to get valuable information from it. I can even access a terminal on it.

Here is what i get on boot:

While this maybe cool and usefull it will suck if i can not create my own code.

The BAD…. Since im mostly interested in the LCD and keyboard and could care less about the processor or anything else i am stuck.
As you might expect there is no datasheet for either and manually reverse engineering both is beyond me since i dont have the necessary tools.

The Ugly… Now what i am trying to figure out is how do i get into a U-Boot.bin file to get all the source. This is beyond me as well. The U-Boot.bin file has the bootloader and from what i can see some LCD init stuff and a ton more. To find out what can be expected in the file i used my Linux OS (debian) to search for strings in the file…

(this is from Cygwin tho easier to copy/paste)

Obviously there is more but i clipped out what wasnt relevant to save scroll space…

I know know there are quite a few things related to the LCD in there which is something i will need. I ran across a program called binwalk and tried it on the uboot bin file and got:

Scan Time:    Jan 10, 2012 @ 22:04:41
Magic File:   /usr/local/etc/binwalk/magic.binwalk
Signatures:   75
Target File:  u-boot.bin
MD5 Checksum: d2c6f4e628ee5594caaccedb95fda7a6
184350         0x2D01E        LZMA compressed data, properties: 0x01, dictionary size: 8388608 bytes, uncompressed size: 128 bytes
185224         0x2D388        LZMA compressed data, properties: 0x03, dictionary size: 8388608 bytes, uncompressed size: 64 bytes
186634         0x2D90A        LZMA compressed data, properties: 0x01, dictionary size: 8388608 bytes, uncompressed size: 4194432 bytes
231695         0x3890F        LZMA compressed data, properties: 0xD8, dictionary size: 65011712 bytes, uncompressed size: 1 bytes

This leads me to believe that there is something i can extract and decompress … Look at address 186634 (0x2D90A) the uncompressed size is 4,194,432 bytes.

That is just about 4MB big… Also since there are strings easily readable in there it also leads me to think that there are most likely normal files i can open. (i hope)


The Only BIG problem im having is… getting the data out of the u-boot.bin which is the main goal. I made a simple program to extract data from a file at a specific offset for a specifiv length and output it to a file. All in binary. While it does the job it doesnt work . I think its because i dont know when the archive ends? Or when it starts really.

While the above binwalk gives me a address i doubt its to the actual compressed file. LZMA compressed file have a magic number which usually is something like :

0x5D, 0x00,0x00,0x08 or something similar. I know the 0x5D is correct. But the above binwalk points to the Properties of said location… like 186634 offset is a 0x01 and not a 0x5D…

So if anyone knows how to extract this stuff please help me out.

Custom USB Software

Ok i just got my scale from It was free but i had to pay $7 shipping. Which isnt bad. This scale is supposed to be used with software ONLY! It has no LCD. Its a model 510 scale. I read online that some one was selling a program which would allow you to use it as a stand alone scale.

So i search and found they are selling it for $2. Which is awesome but im broke and dont like paying anyway. So i opened up c# and created my own little program which works great!

I even ADDED a TARE feature. Take a look.

Scale OFF:

Scale ON:

I may decide to share the code. May not. Not sure if i will get in trouble so sticking to privacy right now on actual code.
