UPDATE: It seems that Adafruit’s people also like know how the things works!
Hi all! Yesterday I was at home and I’ve got on the table a MicroSD adapter. I know, and also imagine, that this kind of adapters are just a contact extension to fit the MicroSD contacts in the SD format. But I need to ‘confirm’ it, so I take the screwdriver to open it, and here’s the result:
This is the adapter that I’ll open and it never will be the same. Once is open, carefully for not break any part, I obtain the three parts that make up the adapter: two plastic covers and the contact extender.
The extender can be removed carefully from the back plastic, and has enough quality for this kind of pieces:
On the MicroSD part, the contacts are folded, and acts like a spring when the microSD is inserted on the adapter:
With this my curiosity is satisfied, at least until I find more things to open 😉
Hi all! I’m continuing here with the last board I design and now I’m continuing testing. It’s a battery-powered small datalogger based on a PIC18F2620 microcontroller. The idea comes a few months ago, talking with a friend. He needs something to monitoring temperature and humidity inside a sea container, for a three weeks travel from Spain to China. Low consumption is important, in order to have maximum autonomy with a small battery. I use a HDC1050 temperature and humidity sensor, and a TEMT6000X01 ambient light sensor. The collected data is stored on a micro SD card. Also the board has a RTC for timestamp, a Li-Ion battery charger, user pushbuttons and leds, and a MCP2221 USB bridge to communicate with the board and configure some parameters through software. Let’s see the board in detail!
UPDATE: Insolito project is again available on Indiegogo so it’s time to support this grat project! You can check all the info here and, of course, any question or suggestion are welcome.
Hi all! A few days ago, start on Indiegogo a new campaign where I’m involved in the last months, the Insolito project. Thanks to Sa’ed Qariab, CEO & Founder of The Walking Tech company, I can participate in this project, designing and manufacturing the first units of this intelligent insoles.
Insolito: a smart insole that enables fitness tracking, app shortcuts and emergency alarms with every movement.
Insolito, by The Walking Tech, was launched earlier today on Indiegogo. The new hardware start-up, The Walking Tech, claims that Insolito is the ultimate wearable that is yet to be invented, as this insole is embedded with a smart system that enables its user to control their lives through foot taps.
Insolito is a comfortable and padded insole that can be inserted into any type of shoes. Once activated, the smart system can be controlled through a phone app that works on iOS and Android phones.
The smart insole is fully equipped with fitness tracking functions. It detects movement and counts the number of steps you walk, distance and speed of walking/running. Moreover, it keeps count of the calories that you burn all through the special circuit and sensors inside the insole.
Better still, Insolito enables you to create app shortcuts through customized foot tap patterns. With Insolito, you can take a selfie, make a call, and open any app with a foot tap. This feature is especially useful for taking photos with your hands free.
In addition to all that, Insolito introduces a special SOS feature that saves you out in emergencies, especially when you cannot reach your phone. In any case of emergency, a special foot tap pattern will activate Insolito to call 911, send a message and your location to your family and friends, and even post to social media for you:
This special insole comes with a wireless charging pad, and with a 30-day long battery. It can be fully charged under one hour.
You can pre-order Insolito today through Indiegogo, with a price starting from $69, and with the worldwide delivery expected to commence in December 2016.
The team behind this product is The Walking Tech, a group of young engineers from Palestine who have been working on fitness devices and wearables for three years.
Insolito Features and Facts:
Fitness tracking: counts steps, distance, speed and calories
App shortcuts: enables the user to run any app, take photos or make calls through foot taps
SOS feature: through a special foot tap, it calls 911, sends messages and posts to social media for you
Wireless charging: Insolito comes with a wireless charging pad and charges in less than an hour
Hi all! After a couple of months with a lot of work, I come here again with the last board I develop before Christmas. It’s a dual USB serial and I2C converter based on two MCP2221Microchip 2.0 USB-Serial bridges. I develop it as a need on my work with the last project I’m involved. I need to monitor a serial communication between two devices. With only one converter, I must choose between RX and TX lines to monitoring the traffic. With this solution, I can listen at the same time TX and RX lines, so the monitoring is more easy. And with a software like Docklight (you can download a free evaluation copy here), you can choose the monitoring option to display both channels. After the break you can find all the technical info of the board!
Hi all! After some time out, due some hard work, I’m here again with a ‘one weekend’ project (in my case, with three childs. Sure it can be done in one afternoon!). I want to start some projects with Arduino and IoT, so the first things I need is an Arduino board, an Ethernet shield and a switch to connect it to the net. Also I need a power supply for the Arduino board, and I think that, better than a external USB AC wall adaptor or power supply, is modify the switch to add it a USB power port that can power the Arduino board. I’ve got at home a TP-Link TL-SF1008D, a simple 8 port 10/100 Mbps switch. So, let’s go to open it and add it the USB port!
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 LAMPANIkea 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!
