Build a 6502 computer

by

Learn how computers work by building and programming a computer with the classic 6502 microprocessor. This was the first truly low-cost microprocessor that started the personal-computing revolution. Versions of 6502 found their way into the Atari 2600, Apple II, Nintendo Entertainment System, Commodore 64, Atari Lynx, BBC Micro and many other computers and game consoles of the era.

In this video series, I’ll build a basic 6502 computer with an LCD display and a few buttons, explain how to program it in assembly, and write a game or two.

A Pair of AI-Powered E.D.I.T.H Smart Glasses You Can Make Yourself

by

The main feature of this device is a small see-through OLED screen that is mounted on one of the glasses lenses. This allows the user to see through the display while reading text, generated by a computer, then passed along using an Arduino over serial. Any text can be shown, but since that’s not really useful the controlling computer takes pictures with a webcam, then extracts any visible text using OpenCV. Text is then sent to WolframAlpha, which searches the Internet and returns (potentially)useful information, or returns the answer to math problems that it sees.

Battery-Free Approach to Ocean Internet of Things

by

Ice caps are melting, garbage islands are floating, and the surface temperature of the ocean is rising but scientists are still struggling to figure out an effective solution for monitoring the depths of our oceans. Scientists want to get a pulse on how the ocean is changing, and to do this they are currently collecting data using battery-powered underwater sensors.

However, batteries can serve as a potential pollutant if they get damaged underwater. A group of MIT researchers is attempting to understand our oceans better without relying on batteries with their innovative battery-free underwater sensors.

Forget 8K, Sony’s New 63-Foot 16K Crystal LED TV Is Now Available—for a Few Million

by

When a new gogglebox drops, it’s always the same drill: The screen gets bigger, the resolution gets better and the design gets bolder. Indeed, it’s difficult for a brand to stand out. Unless you’re Sony and the new TV your peddling is the size of a New York City public bus and also happens to boasts an unheard-of 16K screen.

Earlier this year when Sony unveiled the colossal 63-foot TV—the biggest 16K screen of its kind—it had commercial cinemas in its sights. But, hey, why should theaters have all the fun? Yesterday, the Japanese tech titan announced the Crystal LED display system will be available for home installation.

Build a Tricopter to Inspect the Health of the Plants in Your Garden

by

Keeping up with a garden can be difficult and time-consuming, particularly if you have a large garden — even more so if you have a farm. Checking on every individual plant yourself requires a lot of labor, and a plant’s health isn’t always obvious just from looking at it with your unaided human eyes. Fortunately if you can see in the infrared spectrum, it becomes a lot easier. To do that on a large scale, you can follow Imetomi’s tutorial to create a tricopter drone to inspect your plants.
