Roll your own secure Dropbox alternative

Dropbox is a great software that I have been using for almost 10 years. It has helped me a lot during university, sharing project files, backing up my thesis and much more. It is a great service, but it also comes with a lot of problems regarding security and transparency (I will not get in-depth here). You can check for example, this article, or this one (there are many more if you look for it).

With this security issue in my mind, I decided to roll my own Dropbox-like service. The main difference is that I will know where all files are and that I am the only one with access to the unencrypted files. After building my own simple infrastructure, I decided to write a quick tutorial showing my solution and how you can create your own! Let’s get started…

The main software that we are going to use is called Resilio Sync (previously BitTorrent Sync). It takes care of all the syncronization between computer, mobile and server, just like Dropbox.

Talk nerdy to me! Where I get my electronics updates and news

Ever wondered where is a good place to find new and interesting chips on the market? Questions about electronics and what is happening in the market?

For the engineers and makers out there, the world of electronics can be a bit overwhelmed with so much happening all the time, updates, news and buyouts (specially in the past few months).

I would to use this post to share some of my favorite places to get new chip information, updates and random electronics questions.

IRC

Do you remember IRC? Yes, it’s still alive and strong. Just connect to the Freenode network and you will find many very interesting channels where you can talk electronics, exchange information and ask questions! If you are there, drop a line to spillere (me!).

  • #electronics on Freenode
  • #avr on Freenode
  • #arduino on Freenode

Other

  • Fedevel Academy – Learn awesome PCB designing skills
  • /r/nicechips – Reddit, a great place on the internet where people share their findings in the electronic chips market. Really really good!!

Campus Party Brazil

Hi everyone, I am blogging live from the CampusParty Brazil 2k10 in São Paulo – Brazil, it’s something like a Lan Party but full of presentations, concerts and of course downloading… We have here a 10GB BandWidth internet, and there’s a TV screen showing the bandwidth consumption, and we haven’t used more then 3GB at the same time. (I’m trying my best to beat the record). Another thing that I found cool is that someone started a DC++ Servers, and there’s around 400 people connected to it sharing stuff fullspeed, soon my 500Gb Lacie Drive, that I brought with me empty will be full.

In case you are somewhere around the world and would like to download stuff from us, connect to the DC++ Hub cp2010.no-ip.org and download at a great speed.

Today morning there was some people doing Arduino projects, DIY stuff, Open Sorce presentations and much more. You can check LiveStreaming from the Campus Party Here.

Yesterday Kevin Mitnick was here giving a presentation about the art of deception, what a presentation, really good! If you would like to watch it, I am uploading it too, it’s worth it!

Take care all, I will check my downloads now! 😉

MAKE presents: The LED

As you might already know, I am big of a LED fan, love all it’s light power and low power needed for that. While viewing the RSS from
HackZine I saw a great short video about the history of LEDs and a little about how to use them. I liked, and decided to share with you, hope you likes as much as I.

In case you would like to learn more about leds, you can visit HowStuffWorks and on Wikipedia.

Some projects I’ve used with leds:
