Hi all! Here’s the new project where I’m working a couple of days. Since I develop the SIM900 module and test it, I don’t work with it. Also, I’ve got at home some samples of the MCP2200 USB bridge that I want to test it. So make an USB interface for this board was the perfect idea! This allows to use the SIM900 board with a PC, Raspberry or similar, with the plus of no need external power supply or control signals. Just plug the USB cable on the board and start communicating with the world!
Guadalajara, Spain (May, 2015) – INSPIDE has officially launched “Phii”, its first Android mobile app which will also soon be available on the iPhone. An app exclusively designed to avoid traffic accidents.
Although the number of traffic accidents in Spain has been steadily decreasing since 2001, last year still ended with 1,131 fatalities. Phii was born to help reduce that figure, providing safety to all those involved in traffic, and paying special attention to the most vulnerable ones, such as cyclists and pedestrians.
UPDATE: This project appears on Hackaday’ Blog. For me it’s an honor, I only can say tanks!!!
This project starts a few weeks ago. My six years old daughter usually sleeps with a light on in her bedroom. Talking with her, we decide to hack her LAMPAN Ikea lamp to make some improvements, including a manual RGB controller to set the light colour, a timeout to turn off the light after 30 minutes without changes and a bluetooth connection to control the lamp with a smartphone or tablet. So, if you continue reading the post, you’ll see what we develop! Continue reading
UPDATE: Thanks to Rando, now you can order this PCB on OSH Park. Thanks!!
UPDATE: If you’re interested in mount the board yourself, now you can download the Bill Of Materials (BOM). Happy welding!
Hi all! With a bit of delay, here’s my last work, a PICnano breadboard based on the PIC18F2550 microcontroller. I have in mind a new project and I want to use an small board, like the Arduino Nano board. This new project is battery powered (3,7V Li-Ion battery). After checking the schematics of the Arduino Nano, I see that the microcontroler is powered at 5V. Of course, I can unmount the linear regulator (U3) that is on the board, and bypass the VIN to the microcontroller power supply. But I think it’s funny try to develop a new module when you’ve access to the microcontroller power supply! Also, I want to work with PIC microcontrollers after many years, so here’s what I design!
UPDATE: This board appears on Adafruit’s blog. I’m very happy with this, it’s a great recognition and I only can say Thanks!!!
I’m continuing working with Juan Brito and Danny Macancela from the blog Desafio Ecuador, developing new boards to bring near the technology and programming languages. Our last work is a board to use with the Raspberry Pi and focused to learn Python. The board has the basic elements to start with this language. Also, with the develop of the PCB we remove the wiring, avoiding troubles with connections, inversion polarity…So with this board you only focused in the software develop, because the hardware side will work!
Normally, when I start a project, I use prototyping boards to mount the components and develop the software. When the project is finish, I always have the same trouble: in witch box or enclosure I put the electronics? If you don’t have this in mind at the start of the project, it could be a serious problem. In these years, I discover that is more easy to first find and enclosure and then develop the electronics that do it backwards. Also, I usually develop systems for both indoor / outdoor, so protection against rain and humidity usually it’s a must. For these reasons, I decide to find a good enclosure and develop a prototyping board to use with it. In this post you’ll see the results!
In the last months, I make some boards based on the BeagleBone Black board (three at this time!). In these projects, I only develop the hardware platform, the carrier board where it will be mounted. For the develop of this kind of boards, mechanical information provided by the manufacturer is very important, and enough in the most cases. In the case of the BeagleBone Black board, this info is included in the Reference Manual: BBB_SRM. But I don’t find some interesting distances that I need for my boards, so I take a board, I measure it and here are the results.
Update: In element14 communinty says this project is awesome!
This project starts a few months ago. Juan Brito, author of the blog Desafio Ecuador, contacted with me to talk about Scratch and the opportunities that gives this programming enviroment in the world of education. In his own words:
I and Danny Macancela are convinced that increase the quality of education in schools and colleges do not require big budgets by governments. This ideal of change has led us to develop this project to teach children mathematics and programming. Children can learn maths with fables. The aim of this project is the search of the human talent growth, which starts in the classroom. As Fritjof Capra says, ‘Today we have the knowledge, technology and financial resources to build a sustainable future. All we need is the political will and leadership’
From here, I also want to thank Danny Macancela for his illusion in the project and its economic support.
A brief entry to tell you that Numato people are very happy this year, and from December 2013 and January 2014 they will give a free gift (including worlwide shipping costs) to everyone that shares this message over facebook, twitter or in a blog. Here’s all the info about this mega Give Away. From here, I only can congratulate they for this great initiative.
From Spain, I wish a Merry Christmas for everyone and I hope all of you enjoy this hollidays with your family and friends!!
After some months out, I come back with my last board, the SIM900 Breakout Board. It’s a board based on the popular SIM900 GSM modem, and I design to work with the DSETA board I develop previously. Also, the board can be used without this board, I try to design it in the way that can be used with any microcontroller. From here, I want thanks to Ioannis Kedros from Embedded Day his support in the design of the battery charger, and to Sonia Muñoz, FAE from EBV, a great professional and a better friend, she always helps me when I need. So, let’s go to see what’s inside the board! Continue reading
