Back in the 1980s, there existed a piece of hardware called the “TVGuardian,” which would attempt to censor incoming video in real-time. As recently covered by the wonderful YouTube channel Technology Connections, the TVGuardian reads captioning data as it’s sent and then replaces the bad word(s) with an alternative phrase and also mutes the audio. Upon […]
Going for a hike outdoors is a great way to relieve stress, do some exercise, and get closer to nature, but tracking those adventures can be a challenge. Our recent collaboration with K-Way led Zalmotek to develop a small device that can be paired to a jacket to monitor progress on a wearer’s trek and even […]
As part of his ongoing PorscheKart project, YouTuber Wesley Kagan wanted a better way to steer his V12 custom-built race car, as the previous wheel was simply a mechanical linkage to the front steering. Instead, this new version would closely mimic the layout and functionality of an actual Formula 1 wheel, complete with all of the […]
The cost of a new prosthetic arm can range from several thousand dollars to tens of thousands, putting them out of reach for many people. Ahmad Ikram recognized this need and decided to design and build a far cheaper, open source version that has myoelectric capabilities. To begin this project, Ikram decided upon using the InMoov 3D-printed arm […]
3D printing, the stuff of science fiction only a few short years ago, is becoming more widely available all the time. Buying your own 3D printer to keep in your home is now fairly accessible, with entry-level printers available for just a few hundred dollars. But why would you buy one? It’s easy to think […]
There are few beverages on this planet that enthusiasts take more seriously than espresso. Aficionados care about and tune everything from steam pressure to bean roasting temperature. But espresso machines that provide both accurate and precise adjustments are very expensive — easily several thousand dollars. Fortunately, you can tackle the Gaggiuino project to upgrade an […]
We’re excited to announce the launch of the new Arduino IoT Bundle. This is built to help you dive into the complex and fascinating world of the Internet of Things with even more confidence and possibility — giving you the hardware, software, and components you need to create your own connected IoT projects. So how […]
Robert John likes to keep a constant eye on the current temperature and humidity of his room, as even small fluctuations can lead to uncomfortable conditions. And although he can remotely turn the air conditioning on or off, he still needed a way to track these values throughout the day and log them for future […]
Green (unroasted) coffee beans cost about half as much as their roasted counterparts. By purchasing green coffee beans, you can save quite a bit of money in the long term. Roasting your own coffee beans also gives you much greater control over the flavor profile and caffeine content of your coffee (caffeine content is a […]
Measuring vacuum works in the same way as measuring any other gas pressure, because a perfect vacuum is unachievable and so it is a measure of how close to zero the air pressure inside a container becomes. But typical pressure gauges aren’t meant to measure pressures below ambient atmospheric pressure (vacuums). That requires special sensors […]
