GBCCAT – Gameboy Color Emulator by Nathalis based on GNUBOY, still in development, used hardware is ESP32 WROVER chip, ST7789 1.3″ LCD 240*240px, loading games from microSD card, emulator has been controlled by PS2 (USB) keyboard, source and schematic is avaliable on Github: https://github.com/nathalis/GBCCAT
The new ESP32 has three cores. Two of them are very fast; the third is ultra-low power.
The Arduino IDE typically only uses one of the fast cores. Today:
– We will take full advantage of the second core of the ESP32
– We will test if it really increases the capacity of our microprocessor
– We will also compare its dual-core speed with the speed of an Arduino UNO
– We will try to synchronize tasks, even if they run on two different cores
– We will also try to use the same data on both cores
– These two mechanisms are mandatory if you want to use the two cores in a productive fashion
– And we will not leave the Arduino IDE. Promised
In this video we take a look at an entire hour of super Super Nintendo games facts, spanning everything from Super Mario RPG, to Chrono Trigger, to Donkey Kong Country.
In this video, I test out a Thermoelectric cooler on the Raspberry pi 4 and it worked out really well even when the Raspberry pi is overclocked, it’s actually the best cooler I’ve tested on the I so far. This Cooler uses the Peltier effect and is actually classified as a solid-state active heat pump, It transfers heat from one side of the device to the other using electricity. Basically when you apply power to the heatsink one side gets really hot and one side gets really cold.
The thermoelectric device I use in the video is a low power version but the cold side can still get down to 8 degrees Celsius.
When the original Game Boy arrived, so did hundreds of accessories designed to improve its gameplay experience, including oversized lenses to help magnify its small screen. For the Arduboy Nano, however, you’ll have a better chance at getting the next high score if you stick it under a microscope.
Way back in 2014, Kevin Bates floored us with a credit card-thin electronic business card that put a fully playable game of Tetris in your wallet. That creation eventually went on to become an officially licensed handheld system and inspired the creation of Bates’ Arduboy: an open-source Arduino-based Game Boy clone with a loyal following of developers who’ve created hundreds of free games for it.
If you’ve ever used audio software on the computer, you probably know that MIDI exists: a signalling protocol that allows controllers to control virtual instruments like synths. It’s also the protocol used by real audio hardware to talk to each, and you can think of it as the language in which, rathar than communicating a fluctuating voltage signal or series of discrete sample values, devices talk about what is being done on them (“A4 got pressed”, “F4 got released”, “the mod wheel moved down”, etc).
Christopher Getschmann wanted a wall-sized map of the world. He soon realized, however, that it’s tough to actually buy such a map that’s both beautiful and detailed enough to satisfy his cartographic tastes. While many would simply move on to the next “thing,” Getschmann instead took things into his own hands, and built a pen plotter specifically to draw a massive 2×3 meter map for his wall.
If you live in a house with stairs and have to traipse up and down at night, it’s best to have some sort of light that guides you. Although a cell phone can work just fine, or you could likely activate bright overhead lighting, creator MagicManu devised an automatic and progressive solution to illuminate his path instead.
MagicManu’s system knows when someone is there using PIR sensors arranged at both ends, and only activates if it’s dark enough thanks to a photoresistor. The entire setup is controlled by an Arduino Nano, while two potentiometers adjust light sensitivity and duration of ignition.
According to the incredible success of it’s initial crowdfunding round, most of the internet seemed to have gotten wind of the Flipper Zero back when we covered the kick-off of the Kickstarter, some 6 months ago.
This slick, fine-looking device is touted as a digital Swiss Army knife of sorts — an open hardware platform with peripherals chosen to enable it to poke, probe, and prod nearly every physical interface you are likely to see in a commercial, consumer-grade product.
Designed to get you some insight on your wireless smart light, or reveal the hidden detail of an IrDA transmission, it’s a portable pentesting tool for the discerning hardware “phreaker” on the move.
