Gearbest review: Arduino Mega2560 and LCD keypad demo project

Arduino is an excellent platform for fast prototyping and building projects. But probably one of the best things here is that Arduino layout allows plugging hundreds of standard shields. Today you can probably find any type of sensor, displays, driver included in to shields. This is where comes the real power of using Arduino. Gearbest have supplied us with a great combination of commonly available products, including Arduino Mega2560 and LCD keypad shield. Arduino Mega2560 comes with powerful AVR ATmega2560 microcontroller featuring 54 I/Os, 256KB flash, 4KB of SRAM, and 4KB of EEPROM. It has standard Arduino header layout extended with tens of additional that are not occupied by shields. They can be successfully used with additional gear.

Working In Medicine (Without Being A Nurse)

Many people who want to jump into the healthcare profession are not particularly interested in nursing, where the work can be backbreaking, very dramatic or very dull. It can also involve internal medicine, which may not be your cup of tea. So, what do you do? If you’re looking for rewarding work, but don’t really care for the sight of blood or have worries about the heavy lifting involved in nursing, try these technical job ideas out for size. After all, income levels for peripheral healthcare technicians, such as radiation therapist or sonogram technician, are holding up well, because of the high demand training. Here are some job ideas for smart folks who don’t necessarily care for a traditional job as a nurse or a doctor:

Accessing AVR microcontroller ports with AVR GCC

All AVR ports have Read-modify-write functionality when used for general I/O functionality. The direction of each separate port pin can be changed. Each pin buffer has the symmetric capability with the ability to drive and sink source. The pin driver is strong enough to drive LED directly, but it is not recommended to drive even small loads without using proper driver circuit such as transistors. All port pins have internal selectable pull-up resistors. And finally, all pins have protection diodes to both VCC and GND rails. Each port of AVR consists of three registers DDRx, PORTx, and PINx (where x means port letter). DDRx register selects the direction of port pins. If logic one is written to DDRx then the port is configured to be as output. Zero means that the port is configured as an input. If DDRx is written zero and PORTx is written logic “1” then the port is configured as input with an internal pull-up resistor. Otherwise, if PORTx is written to zero, then the port is configured as input, but pins are set to tri-state, and you might need to connect external pull-up resistors. If PORTx is written to logic “1” and DDRx is set…

Features of classrooms Automated by Linear Actuators

Various features are used to identify the classrooms that have been automated by linear actuation. These features make it easy and simple to ensure that the classrooms are automated. The automated classrooms using the linear actuators are comprised of a single interface that is used in controlling all the equipment in the classroom. This paper will look at the features of the classrooms that are automated using the 12-24 volt linear actuators. The automated classrooms using the linear actuators are comprised of projectors, cameras, computers, speakers, and various equipment used to control the various elements of nature. This includes the regulation of temperature and the intensity of light in the classrooms. The linear actuators are linked to form complex systems that are controlled from one interface. This makes it possible for the students and the instructor to conveniently control the equipment to ensure that they acquire more from the lessons. Some other features associated with the actuators include the automatic opening and closing of doors, moving the tables and chairs, and the camera surveillance for the classroom.

How to drive stepper motor with Arduino motor shield

driwing stepper motor with arduino motor shield

Previously we have driven servo and DC motor using an Arduino motor shield. It is easy to interface with these motors and write the code. This time we get to the stepper motor control and discover the full potential of the motor shield. Stepper motors are more complex devices than servos or DC and require some knowledge before running them. You cannot expect to plug some voltage and see it spinning. Their primary purpose is precise stepping that gives control of how much the motor is turning. You can find a stepper motor in any printer which feeds paper incrementally – and this is where you can get one. Disk drives are another great source to scavenge. We will not get into stepper motor working theory. Do your research before trying to run one.

Why Using Ruby on Rails

Nowadays, many big and small companies prefer using Ruby on Rails when creating applications that are to be delivered on the web. It is not surprising, as Ruby on Rails offers lots of advantages over other web development frameworks. Lets have a closer look at the benefits of Ruby on Rails or Ruby, as it is usually called. This framework’s main advantage is that it makes the life of a web developer easier by allowing writing less code, which is achievable due to a leaner code base. Ruby on Rails is very easy to use. Besides, it gives speed and flexibility that no other scripting language or framework can give. Creating websites with Ruby on Rails is a lot faster and easier than with other web developing solutions. Generally, to develop and launch a website, the developer needs about twelve weeks. While using Ruby on Rails, a web developer needs six weeks to complete a similar project. The modular design of Ruby on Rails allows reusing earlier created elements rather than creating new ones. Making changes and adjustments is also a lot easier if a site is created with Ruby on Rails.

Time to make Raspberry Pi go wireless

Updated on 2019 with simplified settings! Setting WiFi on Raspberry Pi is easier than described earlier. The Raspberry Pi has gone through upgrades and generations, so most of the settings have been simplified. If you set up WiFi using GUI, then it same as on any windows – you select SSID and enter a password. Raspberry pi should be mostly accessed through the console since it is designed to be an embedded computer. This is why it is important to have the ability to do all things in the command line. No matter which raspberry pi you have, you can set wireless networks the same way. If you use Raspberry Pi 1 or 2, you will need a USB wireless adapter. The later boards already come with built-in WiFi and Bluetooth connectivity. To set up WiFi, you need to edit wpa-supplicant configuration file, which can be accessed by entering: To the bottom of file add your network settings as follows: Save settings by pressing CTRL+X and Y to confirm. You may need to reboot your board for the network to connect.

Short PC reinstall became long

Yesterday a friend asked to look at his old computer. He told that computer crashes randomly with Blue Screen of death (BSOD). He suspected to be an HDD problem due to bad sectors or so. He also wanted to save his pictures if nothing else can be done to make it work. Well, I took the PC for inspection. First of all, I tried to save photos – copy them to flash memory. Started up the computer and what you know – Antivirus software expired long ago, the virus is thriving. Found out that it is worm: Win32/Brontok@mm. From its description, I found that: Win32/Brontok is a family of mass-mailing e-mail worms. The worm spreads by sending a copy of itself as an e-mail attachment to e-mail addresses that it gathers from files on the infected computer. It can also copy itself to USB and pen drives. Win32/Brontok can disable antivirus and security software, immediately terminate certain applications, and cause Windows to restart immediately when certain applications run. The worm may also conduct denial of service (DoS) attacks against certain Web sites.

Pressure-less solar collector controller prototype

It’s been over three months since the solar collector was installed. I decided to build a controller by myself. And it turned out that it stayed in the prototype stage. So I put it into the enclosure and left it like is. So far, it works fine – water is hot every day, so I have nothing more to expect. I did not capture enough pictures of the build, but I think I will share what I have. In the forum thread, you probably saw what type of system I was building. As I mentioned, the solar collector is cheaply made in China and is pressureless. They usually come with a unique controller which takes care of the refilling tank, ensuring protection from water freezing and other individual scheduled routines. A pressureless collector usually is first filled with water which heats, and then it is used (mixed with cold). The initial test shows that when the collector is in direct sun, it boils what leads to heater elements’ calcification. Overall lifetime reduces and so efficiency.
