The Rockband 3 Wireless Keytar has no reason to have a midi-out port, or a mod wheel and pitch bend control, octave up-down buttons, program change buttons, a velocity-sensitive 2 octave keybed, or a wireless USB receiver. And yet, it has all of these things. It costs less than £40 secondhand, comes with a strap, and I'm currently using it as a wireless controller for my Nord Electro 6.
Because I was so preoccupied with whether or not I could, I didn’t stop to think if I should.
The USB receiver on the keytar allows it to be plugged into a computer, and some sort of driver/midi software combo can be leveraged to turn this into a fully functioning midi device. I really don't like bringing my laptop to gigs though, so in comes the Raspberry Pi.
Keytar -> Wireless Receiver -> Pi -> USB Midi cable -> Nord
A kind soul has made a driver that converts the raw output of the keytar into midi messages. After installing this on the pi with a fair amount of difficulty and swearing, and getting the script to start at boot without the need for any user input, the pi becomes a plug 'n' play device for Nord-keytar communication. Finally, I can take my funk solos with style, as long as I remember to keep an eye on the keytar battery life. At least if the batteries run out I can preserve some dignity.
Small things can really make a difference. I spend a lot of time at the computer, and if I think about it, I probably put on and take off my headphones unreasonably frequently. Having nowhere to put them grates at my soul, chipping away at my mindset slowly but surely. If we approach desk-sitting like Team Sky approach cycling, we should be considering marginal gains when trying to improve, and so I present the g-clamp headphone stand. Easy to implement, easy to use, fits on any desk, simple and effective. Gone are the anarchic days of madness when I put my headphones in a random spot on the desk. Those crazy times are over. I now know where my headphones are at any time, anywhere.
But wait, I hear you cry, how can I, too, achieve such a state of elegance with my desk-headphone setup? I'm glad you asked, because I made a set of instructions that you can follow to reproduce my configuration. Yes, you too can achieve this marginal gain. Imagine the increased productivity, the saved time, the improved mood! You can find said instructions right here.
There are many animals that exhibit flocking behaviour, including humans. This is an attempt to recreate that behaviour using three simple rules:
Separation - avoid crowding neighbors (short range repulsion)
Alignment - steer towards average heading of neighbors
Cohesion - steer towards average position of neighbors (long range attraction)
So what are the uses except for making pretty (but intensive) screensavers? Well I guess a similar, but probably more complex, simulation could be used to see how crowds of people react in certain situations. I can't for the life of me find the source, but I remember reading that putting a pillar in the middle of a doorway can speed up entry and exit of a tube station, as it forces commuters to line up. At present however, it just makes for a pretty video.
Welcome to the new blog. It's better than the old one.
Hey it's even got https. That's for me not you though, I don't want middle men snooping on my admin password.
Want one for yourself? Get the code on Github
Markdown. Look at these lovely bullet points
Online editor complete with live markdown preview and image uploads, no more SSHing/SFTPing ever!
Near-static auto-generated content. There's a wee bit of JQuery but that's all
Auto-generated unique urls for each post
Upvotes. These are unlimited because there are no user accounts and I'm scared of the GDPR police coming for me if I go down the cookies route
(Plus is it reaaally a problem having unlimited upvotes?)
Unless it gets upvoted so hard the int overflows and comes back round the other end
Probably should do something about that
Password-protected draft posts area
Auto publish date
The nitty gritty
Flask backend, Jinja2 templates are a dream to use, Redis for upvote storage, plain old text file for posts storage (works fine, no real need to mess around with a database), JQuery for the actual upvoting. Find out more on Github
All posts are stored in one big file at the moment. The admin console effectively gives you free reign over editing the file, so you can change past posts, publish dates, post urls, at your leisure. Due to the potential for the utter destruction of all posts ever if you or some nefarious individual deletes everything, post backups are made every time the admin console is used.
As a neutral third party, I'd definitely recommend using this blogging engine.
I spent a short amount of time writing a fairly crude Twitter bot in Python, using Tweepy. It listens to a stream of tweets, looking for ones with keywords like 'win', 'RT', and 'fav'. After passing through a couple of filters to try and determine if this is a genuine competition tweet, it will follow, favourite, and retweet.
It's been running for just over a week now and I've won a few things, most of them digital so far, and all of them pretty much worthless. Included in my winngs are: A random Fortnite account, a cupcake from a stand in Manchester, Grave Danger for PS4, Fear the Wolves beta key on steam, the book 'Fliers' by Laura Mae, and an entire £0.05 sent to me on Paypal.
He said it was meant to be £0.10 but the Paypal fees were too large.
I picked up a MicroKorg for a very reasonable price and haven't been able to stop playing with it since. As a classically trained pianist I always used to (internally) turn my nose up at these sorts of machines - how could you ever make something interesting with so few keys. The MicroKorg has 32 small keys, and it was initially quite difficult to get used t
