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…

Podcast on a floppy disk.

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…

A disk drive.

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…

Ports on a battery.

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…

Game Review: Factorio

A screen saying I've won.

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…

How can I launch a Spotify album from an NFC tag?

Spotify screen showing options.

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 …
