But we do appreciate the clean and orderly technique that [Eric Rogers] uses to add multiple SPI SRAM chips to an Arduino. The heavy lifting is done with a CPLD shield called the Amani 64.

Perhaps if it can be done on an Mbed then someone might even make a ZX81 emulator on the Arduino. We’re great fans of the ZX81 here at Hackaday, for some of us it was that first computer.

To make that actually work, Robofun paired an Arduino board with some capacitive controllers for the base, and connected that to a Raspberry Pi that linked the keyboard to the TV.

Robofun Create has built a fully functional keyboard using Staropramen beer cans, demonstrating once more that the potential of systems like the Arduino and Raspberry Pi is only limited by the ...

This little guy, while simple in nature, acts as a fully functional (and portable) keypad on the go! It comes with two main programs, and it connects easily to your Arduino. It can be used to: 1 ...

The Gesture Keyboard is a device that translates gestures into letters. It’s made by an Arduino Pro Micro, an HC-06 module for Bluetooth communication, and an MPU-6050 accelerometer.
