OctoPi new logo

OctoPi new logo

Hey all,

OctoPi has got a lot of support, and it has been great to see people are adopting it.

I have released a new version of OctoPi, which has the following new features:

  • Support for both Raspberry Pi camera and webcam. Depending on which you plug to the Pi (Thanks to Gina)
  • New version of OctoPrint with ACL support
  • OctoPrint now runs on HTTPS using HAProxy, allowing secure connection to your printer over the internet

Also, we had to change the logo due to it being the Raspberry Pi foundation trademark. Thanks for everyone on the google plus discussion (especially Janina).

Download the image here

Source code and project management is on github here

I will note it was pretty nice get in to this release PiCam support, since I have no camera it required collaboration of both Gina and me, meaning we have a distro now that probably can cope with more hardware than you would have in your average personal configuration.

Also thanks Matvin for the storage, and we also have another mirror lined up in case of a overload, which happened last time.

Enjoy everyone,

Guy

Android backup will keep you safe

Hey all,

Friends keep coming up to me and complaining that they had to wipe all their phone because of some attempt to do something.
However, if you give me a brand-new phone and throw mine out of a high-building window, I won’t stop you, because I have a copy of my phone at home, from that same morning, and I don’t even have to think about it.

Want to feel free again? Not scared that this small thing you carry in your pocket with all your life gets ruined? Well, here is how you do it:

Things you will need

  1. A computer running Linux you can ssh to with Rsync installed, or windows running cygwin with rsync and ssh installed.
  2. Your device needs to be rooted – I am afraid thats a requirement for Titanium backup and all programs that back up app data
  3. Titanium backup – You can use the free version for backing up, but for a single-click restore you will need to pay (I bought it and recommended you do even if its the only thing you ever buy on the play store)
  4. rsync backup for Android – This will back up all your photos and data that isn’t part of your apps, if you don’t root but this is all you want to back up, this post might help you too!
  5. Llama – lets you set location profiles

Build your own Free SMS to Twitter gateway with open source tools and cheap hardware March 27, 2011

SMS Twitter Gateway

SMS Twitter Gateway logo

Hey all,

I am releasing here set of instructions and source that will enable anyone to set up a phone number, that if you SMS it, will post your massage on to your own twitter account. This service is called “Twiter SMS Gate”. The service handles multiple users, and should be easily modified to support other services like statusnet (and with a bit more code maybe even other social networks). The SMS hardware required is any cheap cellphone that can work with gammu-smsd (mine is a fake Nokia from India). Twiter SMS Gate also lets users easily register to it with their own cellphone.

I hope that people that like this idea would start hosting more SMS gates, as we create a wide network of those around the world. SMS Twitter Gate-IL , The Israeli Gate, has been running for a few weeks now and even got covered in the local media here.

The source is written in Python, which includes the phone hardware hooks, webserver, twitter client and database access.

Here is the cellphone used to run my server, just to show you how simple it is to do this, no super-expensive hardware required! (server is also my personal Linux-running PC:

If you have any kind of difficulty setting this up, please give me feedback, so we can make it as easy as possible.

Bumble-B and an ADC with OpenGL make an oscilloscope February 22, 2010

Hi all,

During my small semester break I managed to connect my Bumble-b chip to an analog-digital converter (ADC).

With this I can read voltage changes and send the information to the computer to plot live.

Here is a demonstration video:

How its all connected

The Bumble-b

The Bumble-b

Hi all,

The past week I have been playing around with my new Bumble-b, as I mentioned in my last post. Basically what I did with it is control an LED matrix. After doing that I made it in to a USB Device! Thanks to the simple library LUFA. Now I can use a simple echo > /dev/ttyACM0 command to send a text message to the display. Meaning that I have now /dev/matrix!

In this post I hope to explain how to use the Bumble-b, a  programmable USB chip, including its own built in programmer, for just $20. I would also like to encourage people here in Israel to start playing with this, since its cheap and easy to order way to get started with amateur electronics.

Here is a quick introduction video (followed by a detail post):

bumble-bWhat is the Bumble-b?

The bumble-b is a USB programmable AVR chip with a programmer built in to it (called a breakout board). It is an AVR chip, meaning that its based on something that is widely used (the model is at90usb162). Moreover, since it has a USB connector right on it , this makes the creation of USB devices really simple. But not only USB devices alone.

Car and the controller breadboard

Car and the breadboard

Hey all,

I have been playing with electronics the last few days, and I thought I might show you the outcome.

I basically took a remote controlled car, and connected it to a 16F84 programmable chip, and now I can control the car using C code.

Although I am using a car in this guide, you should be able to close and open any kind of switch. Anything under 15 volts.

For people who have don’t feel like reading all this (and also for those who do), here is an action-packed video of the outcome:

After you saw that, here is how I did this.

Tracking with the Nokia N810, mapper sees satellites.

Tracking with the Nokia N810.

Hey all,

This Passover, I went on a trip in the North of Israel in the Golan heights.

However, apart from enjoying the beauty of nature I thought I might do a little experiment with my Nokia N810, a Linux device with a GPS receiver.

What I did was switch it on at the beginning of the tour and put it back inside my bag, ignoring it most of the time.

The result was a complete GPX file of our tour.

On the Nokia it looked nice, however I wanted to see if I can extract more data at home with the GPX file.I found 3 tools I could do with it.

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 :-)

After a long series of editing, the videos from August penguin are avilable to be watched and downloaded. Thanks to all the people that participated in this voluntary project. The files are available in a flash viewer, or to be downloaded in MP4 and OGG formats.

Moreover, during the editing I have developed two tools for the Cinelerra video editor, those are also available for download.
