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):
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.

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.
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.

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.
Enjoy Watching

Hello all,
I thought I might share a small of report of an event that happened to me in Second Life, and also, I thought i’d use the opportunity to show the podcast world in second life.

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.
