Rohm Semiconductor has developed a Qi-Certified Medium Power Transmitter Reference Design using its BD57020MWV wireless power transmitter IC. ROHM is the first supplier in the world to offer a reference design for medium power that has passed interoperability tests with more than 200 Qi-certified devices and has successfully acquired Qi certification under the medium power specification.

IR Remote Controlled Stepper Motor Using Arduino


AM Bhatt

IR remote controlled stepper motor using ArduinoThe project given here demonstrates how to vary the speed of stepper motor and number of revolutions of it using IR remote (like TV, DVD, AC, STB etc) with the help of Arduino. The project uses a normal set top box (STB) IR remote, TSOP IR sensor, stepper motor driver chip and Arduino UNO board. Anyone can use any type of IR remote.

Just he has to change the remote codes in the Arduino sketch (program) for the remote. This procedure is also described here while explaining the operation. So let us see how this is done. First, see the circuit diagram followed by its description and operation. The stepper motor has many parameters that can be controlled like- Direction of rotation, Speed of rotation, Angle of rotation, and Number of revolutions.

10 Inspirational Movies Based on True Events for Every Tech EnthusiastSince a very long time, the entertainment industry has been playing a major role in getting people close to Science, mainly through Sci-fi flicks and TV shows. However, apart from the Sci-fi subjects, there have been a lot of movies based on the true events of Scientists, Engineers or other reputed personalities that have left a big impact on the audience. Such creations not only impart knowledge but also inspire us as to how we can overcome the challenges and keep on working towards our goals with full conviction.

Here, we have compiled a list of such movies that will give you an insightful picture of Science and Technology while conveying valuable life lessons. Let’s have a quick glance at the compilation of movies that every tech enthusiast must watch

Atmega 32u4 Based USB Controlled LED Series (Part 20/25)


Amanpreet Singh

Atmega 32u4 Based USB Controlled LED SeriesThroughout this USB series, different types of USB devices have been designed and developed. These devices were enumerating with the host computer and then were using Class Specific transfers for further USB communication. Like the Keyboard, Mouse and joystick devices were using interrupt transfers for their operations after enumeration.

Similarly, the audio class devices were using isochronous transfers for their operations after enumeration. The CDC Class devices were using bulk transfers for their operations after enumeration. Any of these transfers (Bulk, Isochronous or Interrupt) are enabled only after the control transfer which let the device get enumerated with the host. These transfers are required when data is also sent from the device to the host computer.

Electricity Anti-Theft System - Over Loading Detection and Automatic Shut Down


Pawan Kumar

Electricity Anti-theft System Block DiagramElectricity theft is a common problem. Due to electricity theft, not only there are losses to the revenue of the government but over loading and damage to the transformers is an unwanted consequence of the theft as well. 

The project demonstrated here is to show the mechanism of electricity anti-theft system. A pack of parallel connected bulbs is used as load while the programmable circuit operating the supply controlling relay is based on Arduino. The principle used behind detecting overloading is voltage comparison and an additional buzzer circuit is attached to the project to alert electricity theft in the locality. The buzzer mechanism has been added to alert people of electricity theft and demoralize the mischievous elements.

3D Printing Processes - Directed Energy Deposition (Part 6/8)

Nikhil A

Directed Energy Deposition 3D PrintingDirected Energy Deposition (DED) is a 3D printing technology specifically used to create 3D models from metals and alloys. The technique can be applied for making 3D parts or objects from polymers, glass or ceramics but is not popular for that. This technique is quite commonly used for repair of existing 3D models built using metal or alloy.

Many times the technique is used for adding extensions to existing metallic models. The typical apparatus for Directed Energy Deposition 3D Printing consist of a head for material wire supply which can move along multiple axis and an electron beam projector or high power laser beam projector which melts the fed wire through directing the high power radiation.

The road to zero-emission vehicles is paved with semiconductors. But the automobile is not a friendly environment: ICs face extreme voltages, currents, temperatures and vibration. Further, electric propulsion needs a battery rated in hundreds of volts, which challenges semiconductor materials, processes, designs, packages, and qualification. Managing the batteries of hybrids and full electric vehicles is a key area for innovative high-voltage technologies.

Shalini Verma

Adafruit has introduced a Raspberry Pi notebook, where a 3D Printed enclosure fits the Pi 2 and a 3.5” PiTFT into a small retro mini laptop. The tinyChiclet keyboard is wireless and characterizes a track pad as well as touch screen on the PiTFT. Further, the device is rechargeable through the Power Boost 1000C and the 2000mAh battery adjusts between the screen and the Raspberry Pi. Additionally, 3D Printed pivots to the enclosure, which makes this as a tiny portable computer.

The device can be used for observing and controlling prints, inspecting the webcams, streaming music or even play text adventures games like Zork. The equipment required for this project are Power boost 1000C, Mini Metal Speaker, Raspberry Pi 2, 3.5" PiTFT, Miniature Keyboard, 3D Printer, Filament, etc.
