Huge thanks to Alistair for sending me a bunch of old floppies to play with. I have a 1Tb disk that will be attached to the PI and will serve as a storage for the media center.
#Raspberry pi disk formatting Bluetooth
I printed the album cover on a Bluetooth Thermal Printer. I looked through it but decided to follow this guide using parted to format the disk from the command line.

I started from the official Raspberry Pi Install Docs and that eventually linked me out to this blog by Norman Dunbar.

I am repurposing one of my Raspberry Pi’s and need to format the microSD card. Go to the directory with your audio in it:ĭecode the file and pass it through to aplay - this should start playing music straight through your headphones. It will probably show us as sda - mount it with
Make sure that the floppy disk has been detected: Make sure you have the Opus tools and codecs installed: Set the headphone volume to 100% (or whatever you fancy): Then choose: Option 7 (Advanced Options), then A4 (Audio), then 1 (Headphones). Set the audio output to go via the headphone jack: I used Raspberry Pi OS Lite which doesn't have a desktop manager, and fits on a 4GB microSD card. I powered it using a USB Battery.Īll held together with rubber-bands. The Pi has a weird combined video / audio jack.
But the USB floppy drive is pretty big, so we don't lose much space by going for a full-sized Pi. Sadly, the Pi Zero doesn't have an an audio out jack. (I've re-encoded it to MP3 in order for it to play in the browser.) Building It Not much worse than fading medium-wave station, right? RIGHT!? This, I hope, falls under the fair dealing exception. Here are some samples which I am using for non-commercial research purposes. So it doesn't expire for another 14 years. Sadly, the law was changed in the UK in 2013. The copyright for Hard Day's Night should have expired in 2014. You can shrink the audio by a few more bytes by using removing the default metadata from. Enough space left over for some low-resolution cover art! That got it down to a trim 1,429,105 bytes. Opusenc hdn.wav -downmix-mono -bitrate 6.7 -framesize 60 -discard-comments -discard-pictures -cvbr hdn.opus I got a single WAV of the album, and ran this command - which is about the best quality within the target filesize: Using the Opus Audio Codec, you can squish audio to miniscule file sizes. OK, I also got sent a USB floppy drive to review and wanted to do something interesting with it! Compress your audioĪ floppy disk can hold a maximum of 1,457,664 Bytes. Beatles audio was designed to be played over crappy AM radio in mono, so is well suited to being compressed using the latest audio codecs. The best band in the world are The Beatles, and their shortest album is A Hard Day's Night - at 30 minutes, 45 seconds.

Also if anyone knows how to submit a patch to the Raspberry Pi docs please let me know.I have built the most inconvenient way of playing music! It is lo-fi awfulness and cyberpunk grungy.Īs I discussed yesterday, it's possible to fit half an hour of speech on a single floppy disk. I’m honestly not sure why this causes such a speed decrease (and it’s definitely worth looking into). Rdiskn is the actual name of the disk which diskn points to. The work around is pretty straight forward: However, I finally discovered the culprit.Īpparently on OS X the disk2s1 name is actually some sort of pointer or symlink to actual name of the drive. You can see Floris’ other software, for data centres, here. Raspberry Pi Imager is fully open source and was originally written as a modification of the PiBakery tool, later modified and finished by Floris Bos (the original writer of the NOOBS tool and the PiServer tool).

Most answers were something along the lines of “Your SD card reader is probably broken”. Download the Raspberry Pi Imager from our downloads page today. Searching around yielded very little help.
#Raspberry pi disk formatting update
Quick Pro-tip: You can bonk ctrl+t while the drive is formatting and get a status update from dd. I let the device format for about an hour before I just gave up. I was following the official flashing instructions and I was having real problems with the speed. Part of the process in setting up a Pi is that you need to flash a SD with one of a I just got a Raspberry Pi 2 for me and my daughter to hack around on.
