Update2: New mirror opened after Dropbox suspended my public links due to traffic. Download the image here.

Update: Dropbox have suspended my Public links due to “extreme traffic activity” so in a few hours I should be syncing the image to other mirrors. Other hosting would be appreciated!

Hey all,

I am happy to say that I am a backer of the Rigidbot 3D printer, (which you can pre-order already), I am expecting it to arrive in August. In the meantime, I have ordered a Raspberry Pi to play with and started visiting a local maker community known as XLN.

This led me to find a really cool project called OctoPrint, which lets you control 3D printers using a Raspberry Pi over a web interface, however people were not installing it on their Pis because there was no out-of-the-box solution. Today I am happy to announce that a solution is here! I give you Octoprint + Rapberry Pi = OctoPi. A raspberry Pi distribution which runs OctoPrint out of the box, with support for time-lapse video on webcams (there is also an experiential version in the works that supports streaming from a raspberry Pi camera).

Just dd the image on to an sd card, put the sd card in your Pi, boot it and connect to the network and printer, then point your browser to http://octopi.local and you have a fully functional 3D printer server! Plug in a webcam and can also make time-lapse videos. Just as simple as that. More details for windows users can be found on OctoPrint’s download page.

The OctoPi image can be downloaded here.

The sources are available on github, and could also serve as a framework to automatically build other Raspbian-based Raspberry Pi distributions.

Pull requests, forks and issue reports are welcome. Also it would be helpful if someone could help me mirroring, since currently the images are hosted on my Dropbox account.

Thanks to Gina, the developer of OctoPrint, for such a great software! PlugWash on #raspbian for the build tips and Richard Mitchell for the last touches to OctoPi’s logo.

Share and enjoy,

Guy

The Jerusalem Echolink Node

The Jerusalem Echolink Node (4Z7GAI-R)

Hey all,

I recently got my amateur HAM Radio license from the Israel ministry of communication. My call sign is 4Z7GAI.

I have been working on getting an Echolink node running on the Jerusalem repeater using Linux. Echolink is a closed proprietary software that lets you connect ham radios to one another and key them across the Internet. Luckily someone wrote a FOSS program called Svxlink, which lets you connect to the Echolink network on Linux., A remote radio control with an echolink server, svxlink-server and an Echolink graphical client, Qtel. I am going to explain in this post how to get svxlink compiled and working (compiling is the hard part). I will also giving out here an Ubuntu package for the lazy ones among you.

I will also add a small section on the physical connection to the radio, an old Icom IC-02AT from the 80s (around my age). (more…)

Sugar running on the Nokia N810
Sugar running on the Nokia N810

Hey all,
This past week I managed to do something quite interesting. I got sugar, running on my Nokia N810, compiled for armel.

The trick that made it work was thanks to easy Debian chroot, that got me access to installing sugar without a few good hours of compilation for arm (and I did that before).

Touchscreen is cool!

The first thing that I found pretty neat was running sugar on a touchscreen device. It really felt better, since most people that I let play with my XO and flip its screen 180 degrees naturally try touching the screen, expecting it had a touchscreen. Sugar was actually quite good with it on the Nokia.

The OLPC system, now you can try it.

The OLPC system

Hey all,

After a few days work, I have finished Building a LiveCD that, by booting from it. You would get a full sugar system, no installation required.

Where to get?

Here, in the Sugarlabs Wiki :-)
