I have built the most inconvenient way of playing music! It is lo-fi awfulness and cyberpunk grungy. Thanks! I hate it! Ingredients Raspberry Pi USB floppy drive Audio Cable / Headphones USB Battery WHY?!?! As I discussed yesterday, it's possible to fit half an hour of speech on a single floppy disk. The best band in the world are The Beatles, and their shortest album is A Hard Day's Night - at 30 minutes, 45 seconds. Beatles audio was designed to be played over crappy AM radio…

An old 3.5 inch floppy disk holds 1.44 MB of data. According to my calculations, that's 1,424 KB blocks. For a total of 1,458,176 Bytes. Once formatted as FAT, you end up with 1,457,664 Bytes of storage. But how much audio can a floppy hold? (Here I mean wave based audio of human speech. It's trivial to fit more in using MIDI or speech synthesis.) I'm going to use "A Podcast Of Unnecessary Detail" to experiment with, as this blogpost also has too much detail. The podcast is a 39MB MP3,…

This rather generic USB Floppy Drive has just arrived for me to review. It's sold by Dainty / ChuangZhiJLB - but it has the same internals as every other floppy drive on the market. It worked instantly in Linux and MacOS. Shows up as a USB drive. Shove a disk in there and your OS should automagically mount it. Appears to draw about 500mW in power. The disk read and write speed is pretty good considering the medium. It only takes a few seconds to read the entire disk. Absolutely no bells and…

The fine folks at Poweradd have sent me one of their gadgets to review. This is their 26800mAh USB-C power bank with Power Delivery. It's pretty similar to most normal portable batteries - but because it has USB-C-PD, it can charge MacBooks, Nintendo Switches, and other high-power devices! Let's take a look: In the box A big black battery. A weird hybrid cable. It is USB-A to Micro-USB and has adapters for USB-C and Apple's Lightning. It isn't a USB-C PD cable. There's also a…

I am rubbish at video games. I don't have the twitch-reaction speed for shooters, I can never remember what all the buttons do, and I frequently get lost in open-world games. Basically, I'm the opposite of my wife, who will rattle through Dragon-Ages, Mass Effects, Spiders-Men and the like. Factorio is sort-of-like Sim City. Or Populous. You have an open, discoverable world, full of natural resources. Your job is to plunder those resources and build a space ship to get you off-world. Factorio …

This is annoying me. So I'm posting in the hope someone can tell me what obvious thing I am missing. I want to tap my phone against an NFC tag hidden in LP sleeve. Then I want my phone to automatically launch the Spotify app and for the app to display that album. This should be simple, but I can't get it to work. Get the album link Spotify gives me an option to copy the album link, or Spotify URI. Either: https://open.spotify.com/album/6QaVfG1pHYl1z15ZxkvVDW…
