To keep the Raspberry Pi Zero as low cost and small as possible, the Pi foundation didn't include a 3.5mm audio jack. There's also no breakout pads for the audio output. This made us a little :( at first but then we thought "hey you know, we can probably figure out how to get audio out with a little hacking!
Inventables' web based digital CNC software, Easel, currently requires a constant connection from a Mac or Windows based machine in order to send commands to the X-Carve over a serial port. This tutorial will show you how you can free up your main computer while the X-Carve is running by using a Raspberry Pi as a bridge to wirelessly send commands to the X-Carve's Arduino Uno. We will also use a Powerswitch Tail to automatically control the main power to the X-Carve when Easel launches in your web browser.
Is this not the cutest little display for the Raspberry Pi? This HAT features a 2.4" display with 320x240 16-bit color pixels and a resistive touch overlay. The HAT uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!
Kali is a security and penetration testing distribution, preloaded with a wide range of network tools and other utilities. If you'd like to use it on a Raspberry Pi with the PiTFT display, there's only one real problem: It uses a custom kernel which doesn't presently include all the stuff you need to use the PiTFT as a touchscreen. We'll go over the basics of an install and remedy the kernel situation.
One of the more noticeable limitations of the Raspberry Pi is using an SD card for its main storage. This guide details hooking up an external drive, copying your root filesystem to it, and configuring the kernel to treat the external drive as root. It includes a helper script which automates most of these steps.
A TFT panel connected to a Raspberry Pi without the use of an HDMI decoder? What is this sorcery??? It's the DPI Kippah from Adafruit! This HAT-like board snaps onto a Raspberry Pi B+, A+ or Pi 2 Model B and with a little software configuration, allows you to have what normally would go out the HDMI port come up on a nice little flat screen.
