bookmark_borderTalk 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.
Newsletters
Podcasts
- The Amp Hour My favorite podcast where Chris Gammell and David Jones talk about electronics!
- Internet Of Things – Everything IoT
- MacroFab Podcast
- Embedded.fm
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
Forum
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!!
This list is still a working in progress. If you have any suggestions please add a comment bellow!
bookmark_borderOpening a popup ninja from php
Checking the documentation from popup ninja plugin on how to open the popup from a link, the only available option is how to open from a blog post. But if you want to add the link in your website using php, you need to use the wordpress function do_shortcode. The documentation doesn’t show how to add a do_shortcode with content between the tags.
To open the popup with php, simply get the popup ID and use the code bellow. Just remember to change the text for your desired one.
< ?php echo do_shortcode( '[ninja-popup ID=1234]'.'text to open popup'.'[/ninja-popup]' ); ?>
bookmark_borderChecking if php-curl is installed
If you wanna check if php-curl extension is installed in your system, type on terminal
sudo php -m | grep "curl"
If the response from the code above is empty, the extension is not being loaded with php. Then you can install it with:
CentOS
yum install php-curl
Ubuntu
sudo apt-get install php5-curl
bookmark_borderMetronome v2.0
During my first semester of Electrical Engineering back in 2007, I had an introduction to electronics class where by the end of the semester we had to develop an open project. At first I tried to build a AM radio using only passive components, I remember that after hours placing components on the breadboard I managed to make it work, but it was really inconsistent and super noisy. The project was working, but it wasn’t as good as I wanted, so I decided to build something else, something that could be actually useful, that when the metronome idea came alive. Using a few components and a 555 IC I could make the circuit “tick” in a frequency that can be used your music studies.
bookmark_borderOne Dollar Board – Cheapest development board on the market
What if you could manufacture a very simple development board that is arduino compatible and have a final price of only ONE DOLLAR!? That’s what some crazy guys from my home country (Brazil) are trying to accomplish.
The main idea of the project is to enable every kid around the globe to leave school knowing how to program, the basic of electronics, and how to apply their knowledge by building cool things. Think like this, with only $25 you can buy 25 boards, which will enable pretty much an entire classroom to own these boards and create amazing things with it. It’s crazy to think the impact that the project can make in poorer areas of the world, enabling those engineering minds to flourish and change the world for better (why not?!).
Check their indiegogo video below and remember that for every dollar invested is one entire new board built!

(of course the project is part of the open hardware movement)
