Pressure Plate LED Coasters!

Looking to use up some more of his flexible LED strip, Hackaday alum and Tindie writer [Jeremy Cook] tried for a funky accent to his dinner or coffee table: light up coasters. Using his CNC router to carve out two pieces of translucent plastic to house four 3V CR2032 batteries,…... [Continue...]

Colorful Display Keeps Track of Your Network

So you’ve built out your complete home automation setup, with little network-connected “things” scattered all around your home. You’ve got net-connected TVs, weather stations, security cameras, and whatever else. More devices means more chances for failure. How do you know that they’re all online and doing what they should? [WTH]’s…... [Continue...]

Hacklet 126 – Teensy Projects

The Arduino has proved to be a great platform for electronics projects. The same goes for the Raspberry Pi. However, there are some projects that fall in the gap between these two options. Projects that need more memory or processing power than the ATmega microcontrollers have to offer, but not…... [Continue...]

Artificial Skylight Brings Sunlight To Any Room

Humans aren’t supposed to be cooped up indoors all day, but who wants to be bothered by UV rays, insects, allergens, traffic, physical activity, and other people? On the other hand, a gloomy living space generally inhibits productivity — if not making it difficult to find what you’re looking for.…... [Continue...]

Now is the Golden Age of Artisanal, Non-Traditional Tube Amps

Earlier in the month, [Elliot Williams] quipped that it had been far too long since we saw a VFD-based amplifier build. Well, that dry spell is over. This week, [kodera2t] started showing off his design for a VFD headphone amp. Here’s the thing, this isn’t using old surplus vacuum fluorescent…... [Continue...]

See a Cheap Smoker get an Automation Power Up

[Jason] learned a lot by successfully automating this meat smoker. This is just the first step in [Jason’s] smoker project. He decided to begin by hacking a cheaper charcoal-fed unit first, before setting his sights on building his own automatic pellet-fed smoker. With a charcoal smoker it’s all about managing the airflow to that…... [Continue...]

From Audio, To 3D Printed Sculpture, And Back Again

Have you ever wondered what a song looks like? What it feels like in your hands? Those odd questions have an answer that has taken shape over at [Reify], which has developed a way to turn sound waves into 3D-printed sculptures. These visualizations made manifest can be made from any…... [Continue...]

The Arduino Sleeps with the Fishes

[Eric Dirgahayu] wanted to explore underwater with some sensors and cameras. First, he needed a platform to carry them. That led to his Arduino-controlled swimming fish. The fish is made from PVC and some waterproof servos. From the video (see below) it isn’t clear how much control the fish has,…... [Continue...]

Creating A PCB In Everything: Eagle, Part 2

In the last (and first) post in this series, we took a look at Eagle. Specifically, we learned how to create a custom part in Eagle. Our goal isn’t just to make our own parts in Eagle, we want to make schematics, boards, and eventually solder a few PCBs. The…... [Continue...]

Finding ESP8266 Inside Big-Box Store IoT Plugs

When we buy new shiny toys, we usually open them up to at least have a look. [Scott Gibson] does the same, apparently. He found an ESP8266 module inside the EcoPlug brand WiFi-controlled wall switches. The original device was intended to be controlled by a (crappy) app. He sniffed the…... [Continue...]

Building Pneumatic Actuators With 3D Printed Molds

Pneumatic actuators offer interesting perspectives in applications like soft robotics and interaction design. [Aidan Leitch] makes his own pneumatic actuators from silicone rubber. His actuators contain embedded air channels that can be filled with pressurized air and completely collapse to a flat sheet when no pressure is applied. The process…... [Continue...]

World’s Biggest, Most Useless AI Machine

In a time when we’re inundated with talk of an impending AI apocalypse it’s nice to see an AI that’s intentionally useless. That AI is HAL 9000. No, not the conflicted HAL from the movie 2001: A Space Odyssey but the World’s Biggest AI Useless Machine HAL built by [Rafael],…... [Continue...]

Hackaday Prize Entry: Dodo 6502 Game System

If you are a gamer of A Certain Age, it’s probable that you retain a soft spot for 8-bit computers and consoles of your youth. For a time when addictive gameplay came through the most minimal of graphics, and when gaming audio was the harshest of square waves rather than immersive soundscapes. Does the previous…...
