WhatsApp Halloween-Themed RFID Talking Doorbell w/ RGB Eyes

by

Despite the fact that making a hilarious yet not deceitful joke with a jack-o’-lantern on Halloween night is not unobtrusive, I decided to create an exceptional event for my guests on Halloween when they ring the doorbell by designing a jack-o’-lantern doorbell with intriguing features. And, not surprisingly, I only let some of my closest friends know about my new doorbell features by giving them registered RFID tags (entrance permits) to make my other guests frightened even a little bit 🙂 In detail, this doorbell talks to the guests and informs the user via WhatsApp when the guests ring the doorbell or show RFID tags or cards.

First of all, to make the doorbell talking with the guests after an interaction, I generated voices from texts for each occasion I wanted the doorbell to talk. You can get more information about how to create voice files over text files in the following sections.

Geekworm’s Voice HAT Gives a RaspberryPi Stereo Microphones, a Built-In Speaker, and RGB LEDs

by

Geekworm has released a new add-on for the Raspberry Pi and compatible single-board computers, designed to make development of voice-activated systems as simple as possible: the dual-microphone Voice HAT.

“Raspberry Pi Voice HAT is a Raspberry Pi dual-microphone expansion board specially designed for AI and voice applications,” the company writes of its most recent release. “It supports Raspberry Pi 4 Model B/3B+/3B/2B. Now you can build a more powerful and flexible voice product that integrates Amazon Alexa voice service, Google Assistant, Baidu AI, etc.”

Pimp Your Commodore with a RaspberryPi!

by

Recently I remembered the VIC-20 from my old days and wondered if I could make something cool and useful out of it. So I came up with the idea of replacing the old guts with a Raspberry Pi and a handful of electronic parts. And here is the result: a cool ARM based Linux computer in an original case that can be used for all kinds of things that modern computers can be used for. Vintage computer games can also be played on it using emulation software such as Vice.

The New Raspberry Pi 400 Looks Amazing! Official RaspberryPi Personal Computer Just Announced!

by

This is just a quick heads up video, The Raspberry Pi Foundation just released the all-new Raspberry Pi 400 Personal Computer Kit and it looks amazing! Powered by the same BCM 2711 CPU that comes in the Raspberry Pi4 but it’s clocked at 1.8Ghz out of the box as opposed to 1.5Ghz! It also has 4GB of ram 2x USB 3.0 ports 1x USB 2.0 AC wifi and full access to the GPIO and it will run basically any OS that the pi 4 can but it comes with a 16Gb Micro SD card pre-loaded with Raspberry Pi OS.
This is something that Raspberry pi has never done and I’m looking forward to testing out the Pi 400 soon.

Pwnagotchi – Pwn all the wifi

by

Pwnagotchi is a modern day take on the Tamagatchi of the 90s, but with a Cyber Security twist. This digital pet derives his happiness by sniffing WPA and WPA2 handshakes which can then be run through hashcat to guess the password. Two or more Pwnagotchis in range of each other will communicate and split the workload. The Pwnagotchi can also send its stats back to the internet to rank your Pwnagotchi against other Pwnagotchis from around the world.

Shooting Bullet Time Sequences with Raspberry Pi

by

Eric Paré is experimenting with Matrix-eseque effects using 15 Raspberry Pi Cameras and Xangle Camera Server software.

Bullet time photography allows a single instant in time to be captured by multiple cameras, enabling one to “spin” around the subject virtually after the fact. It’s perhaps most recognizable from The Matrix film, and more recently Eric ParĂ© has been experimenting with the technique using an array of 15 Raspberry Pi Camera v2 modules and the Xangle Camera Server software package.

As seen in the video below, ParĂ© is by no means a stranger to bullet time, having created some stunning effects with more expensive and physically larger digital cameras. The Pi Camera’s tiny size, however, allows 15 of them to be stuffed very closely together, for what is his best density ever on a multi-camera rig.

Monitor CPU Usage with 12,288 Individually Addressable LEDs

by

Keeping track of how hot your CPU is running can be quite boring, as staring at a list of changing numbers gets old, quickly. That’s why Sebastian from the website There Ought to Be has created a cube with three faces that display CPU usage and temperature statistics. He was inspired to design this when he attended the 36th Chaos Communication Congress and saw the smaller cubes that people were building and using to show particles reacting to changes in the cube’s position. Rather than also making his cube battery powered, Sebastian wanted a stationary device that can plug into the wall, which allows for far more LEDs to be used.
