- Adding an internal speaker to the Pocket CHIP
The Pocket CHIP doesn’t come with internal speakers. It has the GPIO pins for audio, but nothing is hooked up. On the CHIP itself there is a 3.5mm audio jack for connecting headphones, and you can pair a Bluetooth speaker. On the old NTC blog there was a post back in 2016 about adding an internal speaker using a fairly inexpensive PAM8403 amplifier and a speaker. You can find a mirror of the old post from the NTC blog on archive.org

- Adding Global Volume Control to the Pocket CHIP
I’ve been gradually adding internal speakers to each of my Pocket CHIPs lately and found it cumbersome to have to either open alsamixer or use the volume control page in the Pocket CHIP launcher to control volume.

- GameShell Stuff
I bought a ClockworkPi GameShell back in October 2019. I’ve been playing with it a bit lately (in anticipation of the ClockworkPi DevTerm shipping!) and I realised I haven’t yet posted anything about it on here. Here’s some of the hardware mods I’ve made to my GameShell.

- The Raspberry Pi Pico and the Pimoroni Pico RGB Keypad
In January the Raspberry Pi Pico was announced. The Pico is a RP2040 microcontroller featuring a dual-core Arm Cortex-M0+ processor with 264KB internal RAM and support for up to 16MB of off-chip Flash. It’s comparable to certain Arduino or ESP32 boards and at less than £4 per board it’s a well-priced alternative.
- CHIP Stuff
This page is a changing document. I’ll probably add more notes to it in the future. These are just some notes that I’ve put together in the past about flashing and upgrading the CHIP (and Pocket CHIP) computer.

- Using ORCA with FluidSynth on the Pocket CHIP
This post is about using the ORCA livecoding playground on the Pocket CHIP From the ORCA wiki: Orca is a two-dimensional esoteric programming language in which every letter of the alphabet is an operator, where lowercase letters operate on bang, uppercase letters operate each frame. This livecoding language is designed to procedurally generate MIDI, UDP or OSC messages.
