The Pimoroni Speaker pHAT crams an I2S DAC and mono amplifier, a tiny 8Ω 2W speaker, and a 10 LED bar graph all onto one teeny little pHAT. It's the neatest way to add audio to your Pi project, and its beautiful artwork evokes an 80s boombox!
Pimoroni isn't claiming audiophile sound quality, but it's perfect for fun little projects where you want to add sound output – speech, notification sounds, or light music, for example.
Why not combine it with a little USB microphone to make a tiny voice-activated assistant in the style of Amazon's Echo? Or set up a simple Flask API and send audio notifications to it from IFTTT with a simple HTTP request.
It comes as a kit, so you'll have to solder on the female 40 pin header, and screw and solder the speaker on. Check out Pimoroni's assembly guide for more details.

- The DAC sums the two audio channels to mono, rather than just outputting one channel or the other, meaning that you get both channels of audio out of the single speaker
- The dimensions of an assembled Speaker pHAT are (height does not include the female header): H 10mm x L 65mm x B 30mm. The speaker itself measures: H 6mm x L 40mm x 20mm.
- Speaker pHAT won't fit on top of a Pibow Coupé or Pibow Zero due to the height of the speaker.
- It's important that you use four of the included eight nuts as spacers to space the speaker slightly away from the PCB. Not doing this, and having the speaker cone touching the PCB, can result in sound degradation and even damage to the speaker.

This project started life as an alarm clock for my son made to look like the time circuit from the Back to the Future movies. The display can show the time in various formats, including the one from the movies of course.

In one of the display modes it will show the local weather (from my Arduino-powered weathe...
- Mass SD card Image Writer
We've built a mass SD card writer using a Raspberry Pi 3 Model B, some USB hubs and SD card readers. This beast has enough ports to write 49 SD cards at once! At Core Electronics, sometimes logistics hang-ups mean that suppliers cannot meet our demand for pre-flashed SD cards. During these periods we have to pick up the slack by manually imaging blank SD cards we source ourselves. Of course, this is a super-tedious process, and ...
