While the Nintendo GameCube stood deep in the shadows of the PS2 in its day, its controller remains a popular target for all sorts of modifications today — many of them involving LEDs, thanks to a translucent bottom and button option. As an avid player of the Super Smash Bros. series, [goomysmash] is of course […]
What could you do with a dual-core 240 MHz ESP32 that supports Arduino-style programming, with 16 MB of flash, 8 MB of PSRAM, and 520 k of RAM? Oh, let’s throw in a touchscreen, an accelerometer, Wifi, and Bluetooth. Besides that, it fits on your wrist and can show the time? That’s the proposition behind Lilygo T
Use a $9 GSM module & the Hologram network to remotely control any Arduino with Blynk App. Story Blynk is an awesome tool that allows you to build drag and drop apps for controlling hardware remotely! Its perfect for quickly creating useful IoT projects. This tutorial will run you through setting up Blynk for cellular
Espruino is a small computer that anyone can use to control things around it. Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you can’t program, you can still get started quickly with the web-based graphical code editor! The Espruino family started with one

Ever since he was a young boy, [Tyler] has played the silver ball. And like us, he’s had a lifelong fascination with the intricate electromechanical beasts that surround them. In his recently-completed senior year of college, [Tyler] assembled a mechatronics dream team of [Kevin, Cody, and Omar] to help turn those visions into self-playing pinball reality.
The Arduino has been a household name in the hardware market for a long while now and many vendors have released various add-on devices usually called Shields to expand the functionality of Arduino. One such add-on device is the newly launched Sunflower shield that will allow users to add a touchscreen display to any Arduino project.

Screen technologies have evolved over the years since the cathode ray tube was first demonstrated in 1897, we have moved from plasma to LCDs, followed by LEDs, OLEDs, and more recently e-paper which is what we will look into today. Electronic paper/e-paper displays are display devices which were created to mimic the appearance of ink

Most of the temperature measurement techniques around the world require some sort of physical contact between the temperature sensor and the object or environment whose temperature is to be measured, but as technology advanced, this changed too. The need to be able to measure the temperature of an object without physical contact arose. This need

The Chinese based technology company Rigol Technologies has launched a new high-performance oscilloscope series, the MSO/DS7000 Oscilloscopes. This new series incorporates some of Rigol’s latest developed technologies and includes RIGOL’s self-developed ASIC chipset “Phoenix” into it. The introduction of the MSO/DS7000 series oscilloscope will make it the first time for a Chinese enterprise to launch its own developed
7-into-1 Oscilloscope features a 10.1″ touch-color display Continue Reading
A MOSFET known as a metal-oxide-semiconductor-field-effect transistor is a special type of field-effect transistor which has an insulated gate where in this case the voltage determines the conductivity of the device. Just like conventional transistors, they are also used for switching and amplifying signals. MOSFETs are now more commonly used in digital and analog circuits
