bookmark_borderRunning a Helium Miner on DigitalOcean

Posted on by dansku

In this tutorial, we are going to configure a brand new $5/month DigitalOcean server that will run one or multiple Helium miners. Note that by using the link above, you will be rewarded with a $100 credit bonus that is valid for two months, which is perfect to test the platform and also two months of free miner hosting!

I am not going to get into details about what Helium is and how to use it, but it’s an amazing project where people all around the world are getting together to build a HUGE LoraWAN mesh network to enable anyone to have access to an almost-free IoT network. To check more, go to https://www.helium.com.

bookmark_borderA Better Serial Monitor

Posted on by dansku

Today I would like to talk about a very interesting piece of software that I have been using in the past few weeks, called Serial Port Monitor (version 7.0) by Eltima Software.

This software is perfect for when you are developing an application that has a massive amount of information going through the Serial Port. I am currently using it to analyze diagnostic data from one project. Is is great that you can easily save messages for a later use in its own .spm file format.

On the image bellow, you can check the windows that I am currently using: “Terminal View”, showing exactly what is coming from the Serial Port. “Dump View” that shows timestamp, the hex data and the message, and the “Table View”, showing the captured data from the developer’s point of view: it presents the table consisting of the recorded IRPs. Each row represents one IRP and each column represents one single part of IRP. It is interesting to point that the Serial Port Monitor doesn’t block the serial port while in use, meaning that another software can be “blocking” the port and you can still analyze all the data.

In case you wanna know more about it, check the Wiki!

This is a great piece of software, and I am really impressed by the quality of the products from Eltima. I will probably do some more review in the future!

If you are an embedded systems engineer, you should check it out!!!

This work presents an urban intervention using interactive technology. Located within a pedestrian and small vehicles tunnel below a busy road, that connects two parts of the Federal University of Santa Catarina Campus, the intervention creates a new relationship between tunnel and road. It operates as a displacement, transposing the sound of the traffic above to the pedestrians below. A sound sensor captures the sound of cars on the road and transmits a signal to the Arduino board, bringing a sense of chaos into the tunnel from above. The installation was developed as part of the discipline of Interactive Technologies and Creative Processes of the Architecture and Urbanism department at UFSC.

This is the final project from an architecture class project that I helped with.

bookmark_borderMounting a Filesystem via SSH on OSX Mavericks

Posted on by dansku

fuse SSH’ing to a server and doing all the configuration through terminal is easy and very fast, but when you want to edit files and set a remote development environment on your local machine, mounting a remote filesystem over ssh and editing them as the files were in your computer is the way to go.

Right now I’m using the just released OSX Mavericks (OSX 10.9), so for mounting a remote system you will need to do some tricks and tweaks to have it working. I will try to explain step-by-step on how to do it.

bookmark_borderDIY: Home UBUNTU NAS Server

Posted on by dansku

Back in 2003, I used to connect my computer on the my old 32′ TV, those huge and heavy TVs, to watch stuff from the internet, at that time, eMule was ruling the p2p community (can’t talk about USENET right? :} ). Then in 2008 I decided to build a better HTPC (Home Theater PC), a full dedicated computer connected to my TV, with good MotherBoard/VGA/SoundBoard, well, a good computer, with gaming capacities. It was good while it lasted, but you know, it was huge black box below my TV, bit noisy, but it did the job.

bookmark_borderMy new PicPlz Gallery

Posted on by dansku



Yesterday I was playing with the PicPlz API and decided to build a gallery for myself, so I can simply see all my PicPlz pictures in one page, and with the coolness of FancyBox.

You can also use to create your own gallery, simply by going to http://www.danielandrade.net/picplz/?u=USERNAME, changing the USERNAME to your own. And then you have it.

Ah, take a look at my gallery here.

Hope you like it, and use it!!
Let me know what do you think of it.
