In our day-to-day lives we encounter a wide variety of ambient sounds, and in order to highlight noise pollution, Lucía Garbo decided to make an elegant meter.
The device features an outer shell designed in Fusion 360 and 3D-printed, concealing an Arduino Mega, a SparkFun Sound Detector, and associated circuitry inside. Components are neatly connected via a perfboard, which should allow easy modification later.
Blip is really fun despite how hard it is. As long as you know what you are getting into you won’t be disappointed. It does as good of a job as it could have for the time. Though I think it still could have had sliders instead of buttons and probably been more fun. But it’s worth checking out none the less.
In This video, we take a look bath the all-new GeeekPi Acrylic Raspberry Pi Set-top Box Kit. This case/Kit adds full-size HDMI ports to The Raspberry pi 4 and it moves all the ports to the back for a cleaner looking Raspberry pi setup. No drivers are needed so this will work with any Raspberry Pi OS like Retropie, Lakka, Raspberry OS, Batocera, Ubuntu, and many more.
I’ve suggested doing it, but never shown it done.
Today, we’re installing a Ubiquiti UniFi controller onto a Raspberry Pi 4. And we’ve got power left over for the next project too.
In this video, we take look at the all-new NVIDIA Jetson Xavier NX developer kit! This little board is the big brother of the Jetson Nano and rightfully so! With a 6-core NVIDIA Carmel ARM®v8.2 64-bit CPU backed by a 384-core NVIDIA Volta™ GPU with 48 Tensor Cores on paper this looks like a very capable machine. In this video we unbox go over the specs test out some developer demos then move on to see how this thing handles everyday use and finally wrap it up with some Gamecube emulation using the Dolphin emulator! Of course, this is a Raspberry Pi killer but its hard to compare the two because of the huge price difference.
Ever wonder how we made all these crazy machines do all their crazy machine things before computers came along? Wonder no more as we explore the inner workings of a Wurlitzer 3400 series jukebox from 1970!
In terms of the design, if this leak is accurate, then we’re certainly going to see something wildly different from Nvidia in terms of their prior ‘founders edition’ style models. There are, however, a number of factors surrounding these images that do need to be taken into consideration.
This video is part of the Figurable project, which is geared toward people who are curious about IoT security and looking for that first bite of the apple.
If you’re interested in hardware but haven’t had a chance to play with any yet, this one’s for you. In this “hello world”-level reversing project we’re checking out a UART (serial port) and using it to access a shell on a *very* soft target.
If you decide to try it on your own you’ll find an equipment list, walk-through references, and some troubleshooting ideas at the link below.
In this video we will not only find out how a buck converter works and how to calculate its inductance, but we will also learn about different coil types. That means I will show you how the size, core material and temperature can influence a coil and what you need to be aware of when choosing a coil for your converter. Let’s get started!
Qubes OS securely divides a user’s digital life into separate domains (or “qubes”) that are isolated in different virtual machines. This video covers Qubes OS system requirements, installation and setup, along with a demo including workspaces, copying data between Qubes, block device handling, and installing and accessing applications.
