[Giacomo] finds that every once in awhile, he needs to flash a sketch to an Arduino while on the go. While he doesn’t always carry his laptop with him, he almost certainly has his Zipit Z2 on hand. He prefers to use the Zipit because it’s tiny, it uses Debian, has built-in WiFi, and can run for about 5 hours before requiring a recharge. The only shortcoming is that the device lacks a serial port.
Following instructions we featured last year he added a serial port to his device, then built a small converter cable that allows him to connect it to virtually any Arduino. He says it only takes a moment to get avrdude up and running on the Zipit via apt-get, and once that’s done, he is in business. He wrote a short script that saves him from entering the flash command over and over, so the process couldn’t be simpler.
He does mention that since the Zipit does not have a DTR line, Arduino resetting must be done manually. For the convenience of flashing sketches from the palm of our hand, we can deal with that.
Check out the video below for a quick demonstration of his setup.

Considering how hackable the Nexus One is already, we can only imagine a whole new host of interesting things thanks to Ubuntu running on the device. [Max Lee] set his heart out on getting not just Ubuntu on the Nexus One, but also Debian, and he wrote a perfect install guide to help out those wanting to give it a shot.
He cheated a little bit by having Ubuntu run in the background while the X11 interface is simply VNCed, but he still did an awesome job with plenty of pictures and details to help you achieve Ubuntu on your Nexus One.
When it comes to routers, there is one that is hacker’s favorite, the WRT54GL. But a slightly lesser known company, Pirelli with their “Alice Gate2 plus Wi-Fi”, seems to be a popular choice among our Italian friends.
[Esteban] has done everything from installing serial and parallel ports, to unlocking firmware while installing Debian. Our personal favorite is the creative wiring of an additional USB port, where he had to custom create a power circuit to run his webcam and external drive.
[Update: It would appear Roleo, Beghiaro, and Zibri did the actual grunt work at ilpuntotecnicoeadsl and Esteban simply wrote the guides. Thanks for your hard work and hacking skills guys!]
Want 67 Terabytes of local storage? That’ll be $7,867 but only if you build it yourself. Blackblaze sells online storage, but when setting up their company they found the only economical way was to build their own storage pods. Lucky for us they followed the lead of other companies and decided to share how they built their own storage farm using some custom, some consumer, and some open source components.

If you’ve ever tried compile a linux kernel yourself you know the headache of configuring and taking care of dependencies. KernelCheck makes this a point and click process for debian based linux distributions such as Ubuntu. You can use it to compile and install any 2.6.* stable kernel as well as the bleeding edge. KernelCheck even offers custom compilation options such as including kernel patches or rolling in proprietary video drivers. A tutorial (PDF) is also provided so you can see what you’re getting yourself into.

[Anthony] has transformed a simple router board into a fully fledged Debian system. The board is an RB433AH which has a 680Mhz development board with 3 LAN ports and 3 Mini PCI slots intended for routing tasks. At roughly $150, this could be a pretty versatile tool to have around. Possibly more useful than the SheevaPlug.
[ghostwalker] has put together instructions for running X11 on your Android device. This means you can run a full-blown Linux desktop environment on your phone. It requires you to already have a Debian shell on the phone, which we covered earlier. Instead of having to come up with a custom display driver, it’s hooked to a VNC server. You can connect to it using an Android VNC viewer on the phone or via any other VNC client. The how-to suggests either IceWM or the even lighter-weight LXDE for a window manager. You could potentially install Gnome or KDE, but we’d be surprised if it was any faster than dog slow. Let us know if you have any success with this and what you think the best use is.
