Can Ultra-deep Geothermal Contribute to a Sustainable Energy System?

We have a look at the ‘Smart Video Car Kit for Raspberry Pi’ manufactured by SunFounder, a kit for a small Raspberry-Pi-based Wi-Fi-remote-controlled car with color video camera. We built one and tried it; here are our findings and tips.

Many of the IoT solutions you see at trade shows like Embedded World use Amazon Web Services (AWS). This platform is very powerful, robust and secure and therefore has become a kind of 'industry standard'. Amazon has developed 'AWS IoT Core' specifically for Internet of Things applications. If, like me you just want to try it out you can get a free quota of 500,000 messages for a period of 12 months...

Even as a hobbyist you should be just as concerned about your health as about the nasty smells your housemates associate with your “scientific” activity in the basement or circuit cellar. Three ways exist basically to get rid of the smells you love but others hate: 1. Egocentric: place a small ventilator close to your work area. Like 12 V and/or from a PC. This will pull the fumes across a distance of about 10-15 cms so at least it does not get in your eyes and cause irritation (sensitivity differs between people). But in your room… it will remain, as will the smell, just weakened. Not recommend even if you can open a window very close by. 2. Considerate: ditto with the ventilator in place but connected to a dryer hose to exhaust the polluted air preferably to outdoors. Cheap. 3. Responsible: use a device that not only removes the polluted air from your workspace but also cleans it i.e. catches the offending particles in a filter. Provided a strong cleaning activity is guaranteed b

Each medal has a flip side; each mountain, a north-facing slope. The darkest side of YouTube's mass of videos is too often the bevy of rants and negative comments. Here's a pleasant exception, brilliant, and jubilant, from Marco Reps, about Elektor Labs' 6-Digit GPS Synchronized Nixie Clock published in Elektor Magazine edition 5/2016 on page 56, now available as a DIY kit in the Elektor Store.

This glowing new bargraph thermometer from Elektor Labs is based on an Arduino Nano. It offers a beautiful graphical representation of ambient temperature using a Russian IN-9 tube and an illuminated scale with various RGB-controlled colours. The temperature scale in degrees Celsius as well as Fahrenheit extends from 10 °C to 30 °C / 50 °F to 85 °F. The circuit consists of a 5-to-150 V "voltage doubler" step-up converter, an IN-9 tube driver based on a low-voltage rail-to-rail opamp, two RGB LEDs and of course the Nano.

Taking full advantage of the Raspberry Pi’s open architecture, you can customise and program the NanoSound HiFi DAC. With the Volumio software or any other player software and the Infrared Remote Control, NanoSound gives you the best audio performance and experience you can expect from such an audio player.

Elektor LABS proudly present a new kit to help you assemble your VFD-tube Clock from the article published recently. You’ll build it within about 4 hours, pre-cut acrylic sheet case included, using normal soldering tools and any computer with Arduino IDE. To keep the time synchronised our new VFD-tube clock employs an NTP server. Besides time, it also displays date and temperature in several display formats. Various sensors are supported. The RGB background lighting is user configurable (with a wireless Android app).

The electronics hardware startup scene is exploding in the Bay Area. Circuit Launch offers office, lab, and meeting spaces to hardware-focused startups seeking affordable workspaces and a network of engineers, suppliers, and hardware-friendly investors.

R&D in exciting new areas, from AI-based automotive technologies to the Internet of Plants, is creating lucrative opportunities for blue-chip companies and startups alike. Let's review several of the more important electronics industry news stories from the last few days.

Growth, innovation, and success. Recent research reports show that the electronics industry is experiencing promising growth in a variety of areas, from analog IC sales to global semiconductor sales. In other positive news, we learned that 2017 was the best year ever for women inventors. Let’s review.

Innovation abounds in the electronics industry. The world’s best and brightest engineers are rapidly revolutionizing everything from smartphone hardware to “smart road” technologies. Let’s review some of the most interesting electronics industry news stories from the past several days.
