ATTiny45/ATTiny85 Infra-Red PS2 Keybard (ATIR)
Original project is on http://www.circuitcellar.com/avr2006/winners/AT3296.htm published in AVR contest 06 by Steven Savage. But the link is not available any more.
The interface plugs into a PS2 keyboard port on the PC and accepts commands from the infrared remote. I'm using an ordinary DVD remote (38KHz) to control my computer.
The original schematic is not correct, I had make the correction for PC Data & PC Clock of SV1.
Run Android 2.3 on VirtualBox
I choose Android 2.3 because I own a Samsung GALAXY Y (S5360) hand phone which preloaded with Android 2.3. I always test the applications on my computer before I download to the hand phone.
Fun_Plug 0.5 on D-Link DNS-320 ShareCenter
Fun_plug is a collection of applications compiled and packaged by fonz. fun_plug is install on top of D-Link firmware. It is much more powerful than the D-Link original firmware. The following modules is install by default:
- Lighttpd – a lightweight HTTP server for hosting web pages on the NAS
- OpenSSH – Secure Shell (which you already used to login to the NAS)
- Mediatomb – a UPnP media server (alternative to the one provided by Conceptronic)
- NTP – Network Time Daemon (to synchronize the NAS’ clock with accurate time servers on the Internet)
- UNFS3 – user-space NFS server (a file server protocol which is often used by computers running Linux)
- NFS-Utils – NFS server (efficient file transfer and synchronization utility)
This guide is based on fun_plug 0.5 & D-Link DNS-320 ShareCenter and assumes an SATA hard disk is installing to the DNS-320 ShareCenter formatted as ext3.
TP-Link TL-WR1043ND restore from DD-WRT to Original Firmware
- TP-Link TL-WR1043 stock firmware: http://www.divshare.com/download/19132686-eec
- WinSCP: http://winscp.net/
- PuTTY: http://www.putty.org/
- WinSCP is an open source free SFTP client, SCP client, FTPS client and FTP client for Windows. Its main function is file transfer between a local and a remote computer. I use this sofware to transfer files from my WinXP computer to the router.
- PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms. I use this software to SSH to router & perform flashing command.
- Open up a browser and navigate to http://192.168.1.1 (you should use your own IP)
- Login in to DD-WRT.
- Goto Services tab and enable SSH
- Goto Administration/Management and enable SSH
Copy firmware file to Router
- Unzip the downloaded firmware file to any folder, now you have wr1043nv1_en_3_13_10_up(120210).bin in your computer
- Run WinSCP
- Transfer wr1043nv1_en_3_13_10_up(120210).bin to /tmp of router
- You may want to rename the firmware filename to shorter one, I renamed it to a.bin
- Run PuTTY (SSH to router)
- Enter command as blow
mtd -r write a.bin linux
The router will reboot upon flashing successfully

HTML Onclick Image Button with CSS
This is a tutorial to show image button on webpage, it use CSS.
See http://www.w3schools.com/css/default.asp for more information.
Below is an example to show two image buttons. <div class="img"> is the CSS, it is not define in this example, but it is working without any CSS style.
HTML Onclick Button Image
There is few ways to show image button on the webpage. Here I use <a.
|<a target="_parent" href="/newWebPage.php"><img src="/images/light_on.png" alt="Light" /></a>|
Above example shows an image with event. newWebPage.php will open if user click on the image.
- target="_parent" means open a new page when user click on the image. See http://www.w3schools.com/tags/att_a_target.asp for more information
- href= is the action. It will open newWebPage.php when user click on the image.
- img src= show the image on the page. It support many formats such as png, jpg, gif, bmp & others. I often use png & gif (animation) format since both support transparent.
- alt= will show the text if the associated image is not exist.
Note: IE8 and Google Chrome show output differently. There is a rectangular frame around the image if loaded with IE8, while Google Chrome did not show any frame.
See http://www.w3schools.com/tags/tag_a.asp for more information on how to use <a
Below example shows four images aligned in horizontally:
<a target="_parent" href="/newWebPage.php"><img src="/images/light_on.png" alt="Light" /></a>
