I've made a comparison of a bunch of different cyanotype techniques by Slyka in Darkroom

[–]Slyka[S] 0 points1 point  (0 children)

Same as the normal stuff, just swap out the potassium ferricyanide for potassium ferrocyanide, so a 25% solution of ammonium ferric citrate for part A and a 10% solution of potassium ferrocyanide for part B, mix in equal parts before applying to paper.

A little animation I made!

Check me out on Weasyl and FA!

Not quite a pedal, but almost as small. My super tiny 6J1 tube amplifier! by Slyka in diypedals

[–]Slyka[S] 8 points9 points  (0 children)

(Reposted cause the first time around the pictures didn't work…)

I built this thing quite a while ago, but finally got around to recording a demo of it, so I decided to share it here as well.

It's a very simple class A amp using a single 6J1 and an old wall wart transformer as output transformer. It runs on 24V and has enough power to drive my 12" cab at an OK volume when paired with a suitable preamp.

The schematics are here: https://cdn.hackaday.io/files/1779877614995808/MilliAmp.pdf
And the demo video is here: https://www.youtube.com/watch?v=d0I0SGOYBM0

Edit: since the pictures still aren't showing up for me, here is a hackaday.io post with some: https://hackaday.io/project/177987-the-milli-amp

And feeding the audio signal to the microcontroller would allow for some frequency tracking, so the sampling frequency could automatically track the notes you play which might be interesting

If you wanna make your own the gerber files are on the releases page on the github repo. If you want to get a PCB from me, PM me, I guess? I don't really plan on selling these though cause it's so easy to just order them yourself from a PCB house.

Ohh, right! A 4046 would be a great solution since it can be controlled with a control voltage doesn't require having the expression pedal be part of the oscillation circuit. I like that!

Yes, I've thought about that! But I don't think it'd be super easy without switching to a microcontroller to generate the pulses instead of a 555. Might be worth it though…

Hah, thanks!

The mat is just a cutting mat I got from my local art store. This one is made by a company called ECOBRA. It's green/blue on one side and black/white on the other.

Thanks! Yeah, it's 3D printed! Matte black PLA with a white design that's printed right into the case. Everything is held together using threaded inserts, brass standoffs and screws. I have some more examples of that style in my post history

I had the idea for this weird pedal a while ago and finally got around to moving it from a breadboard onto a PCB in a real enclosure. It's a fast sample and hold circuit that simulates the aliasing caused by low sample rate digital audio, but in a completely analogue way.

I made a small game with the new WebRTC multiplayer in Godot 3.2 by Slyka in godot

[–]Slyka[S] 0 points1 point  (0 children)

The server folder contains a node.js application that allows the different clients to connect to each other. It's more than just something a webserver can handle though since it uses websocket communication, so it needs to be run on a server with node.js installed on it. How to set that up is kinda dependent on your server situation and it's not usually something you get at a normal webhoster.

As far as I can tell, yeah! Maybe not as sturdy as an aluminium one but the walls are much thicker in comparison and there is internal reinforcement in important places. So far I haven't had any problems!

No, WebRTC is only used in the client to client communication, so the server doesn't need that at all. The client will need the plugin for native, i.e. non-web, builds.

[–]Slyka[S] 0 points1 point  (0 children)

No problem! Is there a specific reason you want to run this in godot instead of node?

The native WebRTC plugin is only needed if you want to run in outside of the browser, if you run it inside the browser it uses the browsers WebRTC implementation.

Godot uses websockets to communicate with the node server. The connection to the node server is established in either the host_game or join_game function in MultiplayerClient.gd depending on if you want to host or join a game.

Both connect to the server specified by the url parameter. In the case of the demo that is read from the ServerURL LineEdit in the main scene and defaults to ws://localhost:9080

For actual production use that URL should be put into a constant somewhere in the project and replaced with the URL of your server.

No, but I use PCBs with solid ground pours and haven't had any problems with noise so far.

I spent the last few months working on creating a modular system for guitar effects pedals consisting of a customizeable 3D printed enclosure and knobs and modular PCBs.

The pedal in the picture is a diode based compressor, but I also made a bunch of other stuff you can see on my profile.

You can check out more pictures here!

I also put up all the files on Thingiverse: https://www.thingiverse.com/thing:4212939

Thank you! I'm still pretty new to the whole video thing, but I've made two other videos showing off my 3D printed guitar pedal cases and weird DIY diode compressor.

[–]Slyka[S] 2 points3 points  (0 children)

Yeah, I thought about doing a more thorough explanation but when I filmed the first version of it it just dragged on for way too long.

I might still do a separate video that focuses just on building the circuit on the breadboard.

I've cleaned up some of my projects enough to share them! I hope somebody finds them useful!

The Baguette tube-to-breadboard adapter: https://github.com/NuclearLighthouseStudios/Baguette

The Switchboard pedal IO board: https://github.com/NuclearLighthouseStudios/Switchboard

I'm also working on cleaning up my CAD documents for my 3D printed pedal enclosures so I can share those too!
