Using Raspberry Pi 400 keyboard PC as a USB keyboard for your PC

Raspberry Pi 400 USB keyboard

Let’s try not to get confused, but you can now use Raspberry Pi 400 keyboard PC as a standard USB keyboard, optionally with a mouse attached to it, for your computer, or twisted minds may even connect it to a Raspberry Pi SBC… “But why?” you may ask. Because we can. That’s now possible thanks to work from Phil Howard (Gadgetoid), software lead of Pimoroni, and his Pi400kb project which implements a raw HID keyboard forwarder that turns the Raspberry Pi 400 into a standard USB keyboard. All you need to do is to find a USB-C to USB-A cable to connect the Raspberry Pi 400 to one of the USB ports on your computer, change some Raspberry Pi OS configuration, and install and run pi400kb. Add dtoverlay=dwc2 to /boot/config.txt in order to use the dwc2 USB device/gadget mode, and reboot your Pi 400 Load the libcomposite kernel module, get […]

25-key ESP32 Touch Matrix makes good use of ESP32’s touch sensor interface

ESP32 Touch Matrix

Besides the addition of Bluetooth, there are many differences between ESP8266 and ESP32 and one of the lesser-known interfaces may be ESP32’s touch sensor interface. India-based Electro Point’s ESP32 Touch Matrix makes good use of the touch sensor interface with 25 touch pads arranged in a 5×5 matrix creating a wireless keypad that could connect over WiFi or Bluetooth to a host. ESP32 Touch Matrix board specifications: Wireless module – ESP32-WROOM-32U with Espressif ESP32-D0WD dual-core Tensilica processor, 32Mbit SPI flash, 2.4 GHz WiFi, and Bluetooth LE connectivity 25 keys arranged in a 5×5 matrix Expansion – 4-pin I2C header for expansion, e.g. an OLED display Programming – Programming headers Misc – RGB status indicator, EN button Power Supply – 5V input via 2-pin header; built-in 3.3v regulator for ESP32 Dimensions – TBD When a capacitive load, such as a human hand) is in close proximity to the sense-pad, the sensor […]

Arduino powered 5-key keypad includes a rotary encoder

JC Pro Macro - Arduino Keyboard with Rotary Encoder

There was a time when people were happy to interact with their computer with a standard keyboard and mouse.  But in recent years, we’ve noticed more programmable, custom-designed keyboards with more ergonomy, a built-in touchscreen display, integrated into a multi-function USB dock/hub, as well as tiny keypads with a couple of mechanical keys to speed up specific functions. JC Pro Macro is another one of those compact USB keypads. Powered by an Arduino Pro Micro board, the keypad features five mechanical keyboard keys, and adds a rotary encoder, plus an optional I2C OLED display for debugging, and some I/Os to control external hardware like a fan. JC Pro Macro keyboard’s features and specifications: MCU board – Arduino Pro Micro compatible board with Microchip ATmega32U4 AVR microcontroller User input 5x programmable keyswitches Rotary encoder to control volume or other “rotary-y” elements, plus a 6th input switch, i.e. you can press it […]

Keyboardio Model 100 wooden keyboard runs open-source Arduino firmware (Crowdfunding)

Keyboardio Model 100

Are you bored with keyboard news yet? Keyboardio Model 100 does not quite look like most keyboards though. It’s basically a piece of art with an enclosure made of walnut or maple hardwood, and designed as an ergonomic keyboard with left and right parts with a total of 64 mechanical switches with RGB LEDs and custom-sculpted keycaps. Keyboardio Model 100 also runs Kaleidoscope open-source firmware programmed in the Arduino IDE, and can be customized by the user with Chrysalis open-source, cross-platform graphical configuration tool. The community is also working on porting QMK firmware to the keyboard. The Keyboardio Model 100 ships with QWERTY keycaps, but alternative keycap sets with Dvorak, Colemak, Linear A, or blank legends are available as a add-on. Other accessories include a 1.5 USB-A to USB C cable for connection to the host, a 10cm  RJ45 interconnect cable and a 1m RJ45 interconnect cable to connect the […]
