Having explained the theory, let’s see in practice the project of the SEPIC power supply. In this post we discussed – on a theoretical level (even if in a simplified way) – the SEPIC switching converters, also highlighting advantages and disadvantages, and giving you the basics for the calculation of their components. Let’s…
The first of her kind, Lucy illuminates indoor spaces with sunshine. She’s solar powered, portable, and Italian-designed. Lucy moves sunlight from where it’s wasted to where it’s needed. You can place Lucy anywhere with no installation and she will brighten up any room in your home or office with healthy natural light. Let the sun…
The SEPIC configuration, a very useful one, is used in modern converters for mixed supply systems. Thanks to the availability of an always growing number of specialized integrated circuits that realize – with the help of very few external components – some complete and valid voltage regulators, today the switching technology is the most…
TI released today the first reference project to add WiFi and remote control to the J1772 standard EV recharging stations. The WiFi connectivity will open the market to create more and more applications, from EV Home Automation to EV charging stations geolocalization through apps. The TIDC-EVSE-WIFI verified TI Design details how to implement J1772-compliant…
The possibility to transfer electric power by means of electromagnetic waves was proved for the first time by Nikola Tesla, in 1890: he probably could not imagine how the discovery would have been appreciated nowadays. Standard Qi and wireless charge are terms that overwhelmingly entered the consumer sector, and in particular as for…
Facebook is clearly very serious about its mission to connect the world and in the process, it has launched solar-powered drones that use lasers to connect to each other and the ground, and more prosaic efforts like new antennas for covering both urban and rural areas. Today, Facebook is expanding this work with the launch…
One way vendors have been able to keep costs down is by requiring buyers to dedicate a PC to driving the printer. Because it can take hours, or even days, for a print to complete, it can become quite inconvenient to have to leave a laptop sitting next to the printer, merely to make sure…
We have been hard at work for 2 years perfecting the case, reinventing mechanics, re-engineering micro-chips, and discovering a completely new line of materials called Daylight Resins. This amazing portable 3D resin printer, that uses your smartphone as projector and guarantees a really high definition printing output. Filippo Moroni opens the Kickstarter campaign and gathers…
The HACKberry is a 3D printable electric prosthetic arm created by exiii Inc a Japanese robotics company based in Tokyo and specialised in bionic arms. The hand works by detecting when nerve and muscle tissue is stimulated by signals from the brain and sends that data to an onboard micro controller to translate into hand…
FTDI Chip is using Kickstarter to fund an open source reference design for an Arduino UNO compatible board. The NerO is based on the company’s FT231X USB UART, and delivers 5V at 1A without overheating. It is described as an “Energy Efficient Arduino UNO Compatible Design”. “With NerO we wanted to take a whole new…
Third prize on Hackaday Prize 2015 goes to LEUV, a nice project helping developing Countries to move freely! Transportation is major issue in the poorest areas of the world. Places like where I live in South Sudan often have limited physical infrastructure and most vehicles can’t deal with the terrible roads. Specialty off road vehicles…
OEM is a project to develop open-source energy monitoring tools to help us relate to our use of energy, our energy systems and the challenge of sustainable energy. Wireless sensor nodes sending data at to a web-connected Raspberry Pi base-station. Supports home energy, solar PV and remote temperature monitoring plug-and-play out of the box. Fully open-source Arduino IDE compatible…
