Running Your Android Phone/Tablet on a virtual machine January 5, 2013Posted by GuySoft in Android, diy, Hamakor, linux, open source, Uncategorized.

My phone has died, and was sent to repair. And since I have a complete backup of it, as explained in my last post, I thought I might try and emulate it on my laptop.
So in this post I’ll explain how to do just that. And one the side effects is that I can now use whatsapp on my PC!
What you will need
- A backup of your phone that was done with Titanium Backup – Follow my previous post on how to do that. Note that for Titanium Backup to run you need to root your phone.
- A computer that is running virtual box and virtualbox-fuse – I will show how to do this in Linux, but windows and Mac can do this too.
- A copy of AndoVM – This is the reason we can do this, since android by default does not come with an Ethernet drivers and AndroVM is compiled and distributed to run on virtualbox out of the box (pun intended).

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):
What 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.
Connecting a programmable chip to a remote Controlled Car September 11, 2009Posted by GuySoft in Crictor, Electronics, Hamakor, ITU, linux, open source, programming, Uncategorized, wireless.

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.

This weekend I am once again editing the video of the lectures we took at August Penguin, the Israeli open source community yearly meeting. This year it was kinda hard because there were two lectures being given simultaneous, so there are about 8 hours of video to edit.
Like last time, I am editing the videos with Cinelerra, the open source video editor. Last year I also wrote a post in Hebrew while editing the video, and I was hoping to keep the tradition. Also, this year, I have a little code surprise.
How to build “cantenna”, a wave guide antenna out of a coffee can November 27, 2007Posted by GuySoft in cantenna, Crictor, diy, Hamakor, linux, open source, wifi, wireless.

This is really a translation of a post I wrote in Hebrew out of Linmagazine.
Here is my own DIY guide to build a waveguide antenna. This antenna will dramatically boost your wireless connection to a specific direction, enabling connectivity to great distances.
