How can I convert .bin to .img for router (OpenWRT) reflash?

I am trying to get my head around installing OpenWRT on my Netgear dg834gt. I have found the hardware page, identified the correct image and downloaded it. As per instructions I attempted to pass the .bin file to the web interface, however the web interface only accepts .img files. Is there any method of converting between these presumably different formats? I could get a jtag/serial connection to the target but I'm waiting on a cable, so the Web interface would be preferable. Any help is appreciated, Thanks in advance, Drew p.s. I'm a Linux user. Also, I have no idea if this is a daft question or not.

Dropbox application in background process on OpenWRT processor of my Arduino Yun.

Hello everybody, Simple question: does the Arduino YUN support the same DROPBOX functionalities as my laptop? Basically, I need to download data from the SD card of my Arduino Yun to my application server. But the internet connection of my Arduino is not very stable. How I want it to work: 1.    I have a sketch that writes data on a TXT file to my SD card every 10 minutes 2.    I want to install Dropbox on my Arduino Yun 3.    Then, whenever the Yun is connected, it will synchronize all the files from the SD Card with my Dropbox folder on my server. That would happen (I guess) in the background, without my Arduino needing to run a sketch. To do that, I think I need drobox to run ‘in the background’ on my Arduino microprocessor. Did anyone do this before? Thanks. What does NOT work: Initially, I used the "LogToDropbox" sketch inserted in the "Datalogging to Dropbox with Arduino Yun" tutorial at the following link: https://www.instructables.com/id/Datalogging-to-Dropbox-with-Arduino-Yun/ in order to ‘actively’ upload files to my Dropbox app console from my SD card with an internet connection. But if , my Arduino Yun is losing the internet connection, it is impossible to upload the files created during the downtime to my Dropbox app console. These files are stored on the SD card plugged on the Yun during this time interval, but not synchronized.

Tethered wireless shooting with TP-Link router

Hi.... I've been following the instructable about wireless tethering using the TP-Link MR3040 portable router (https://www.instructables.com/id/Wireless-tethered-shooting-with-any-DSLR-camera-V3/) This is great and works very well. My problem is that the router in the instructable is now obsolete in the UK so I was wondering if anyone knows if the TP-Link MR3020 can be flashed with the same firmware? If not are there any other compatible portable routers on the market. I understand the firmware is based upon the OpenWRT firmware but that the author has added some additional scripts, if I can't find a suitable replacement router does anyone know what additional scrips have been added and if it's possible to add them to the OpenWRT 3020 firmware. Many thanks for any help.

Build a device to remotely manipulate news in other people's browsers.

Hi all. We have written a HOWTO for building a small innocuous wall-plug that gives you the ability to remotely manipulate news read by other people on wireless hotspots. Devices affected include laptops, tablet computers (iPads etc) and smartphones. It can be built for under 50 euro. How to Build a Newstweek Device. The device consists of small Atheros based router and wall plug enclosure. We have made OpenWrt based firmware that can be easily flashed onto the router's 4Mb memory. Once plugged into the wall it can be configured using the browser and then remotely controlled using a browser interface. Tweekers can easily add text from a news site they wish to change and provide their substitution. It then sits on the server waiting for retrieval by the Newstweek device. When the device has retrieved the filter it then modifies the LAN, ensuring all wireless packets pass through itself before going to their destination. This is done using a well known 'attack' that rewrites the ARP table on both router and clients. If text in a payload matches the filter, it is changed before being passed onto the client. Sites currently affected include: BBC CNN Le Monde Lenta Ru Le Figaro Der Spiegel Il Tempo El Mundo The Guardian (with many more to come) Here's a video about the project in general: Newstweek: fixing the facts from newstweek on Vimeo . Here is a detailed demonstration of a Newstweek in action. It is intended for the networking enthusiast. Newstweek: The Thorough Demonstration from newstweek on Vimeo. The Newstweek project page is here. I has links to articles, interviews and other information hidden throughout the site: http://newstweek.com Enjoy, The Newstweek Team.
