[ad_1] Since the dawn of the industrial revolution, humans have been searching for more energy. Especially lately, there has been a huge interest in wind, solar, geothermal, and other ways to capture and harness power. However, we have a huge power plant just eight light minutes away: our sun. Oh sure, we toy with solar […]

[ad_1] Today, we revisit another board from [Exentio] – a HDMI/DVI to LVDS transmitter for the Sony Vaio P display. This board is cool to review – it has a high-speed serial interface, a parallel interface, a healthy amount of power distribution that can be tricky to route, and many connectors to look over. I’ve […]

[ad_1] The Apple II was launched in 1977, a full 47 years ago. The Apple IIe came out six years later, with a higher level of integration and a raft of new useful features. Apple eventually ended production of the whole Apple II line in 1993, but that wasn’t the end. People like [James Lewis] […]

[ad_1] As [Electronoobs] points out, everything has resistance. So, how hard can it be to make a high-power resistor? In the video below, he examines a commercial power resistor and how to make your own using nichrome wire. Sure, in theory, you can use a long piece of wire, but normally, you want to minimize […]

[ad_1] Today schools hand out Chromebooks like they’re candy, but in the early 1990s, the idea of giving each student a laptop was laughable unless your zip code happened to be 90210. That said, there was an obvious advantage to giving students electronic devices to write with, especially if the resulting text could be easily […]

[ad_1] Raspberry Pi enthusiasts wanting to connect their projects to the Arduino Cloud using Python might be interested in a guide specifically created by the official Arduino team. Raspberry Pi GPIO control with Arduino Cloud is a crucial aspect of many Internet of Things (IoT) projects. By leveraging the power of Python programming and the […]

[ad_1] [Mellow_Labs] was asked to create a GPS speedometer. It seems simple, but of course, the devil is in the details. You can see the process and the result in the video below. We have to admit that he does things step-by-step. The first step was to test the GPS module’s interface. Then, he tried […]

[ad_1] [Alex R2AUK] has been busy creating version two of a homebrew all-band ham radio transceiver. The unit has a number of features you don’t always see in homebrew radios. It covers the 80, 40, 30, 20, 17, 15, 12, and 10 meter bands. The receiver is a single-IF design with AGC. The transmitter provides […]

[ad_1] For many decades, the USA has been at the forefront of astronomy, whether with ground-based telescopes or space-based observatories like Hubble and the JWST. Yet this is now at risk as US astronomers are forced to choose between funding either the Giant Magellan Telescope (GMT) or the Thirty Meter Telescope (TMT) as part of […]

[ad_1] As a Python developer, you’re probably eager to control and monitor your Raspberry Pi GPIOs remotely. Well, you have landed in the right place.  This article builds upon our previous introduction to “Visualize your Raspberry Pi data with Arduino Cloud | Part I.” Now, we’ll explore using Python to configure Raspberry Pi GPIOs, a […]
