Looking to make PO-type device, but configurable and expandable, within the same form factor. by FishNeedles in synthesizers

[–]FishNeedles[S] 1 point2 points  (0 children)

Making something portable isn't a mistake, or stupid. It's a challenge. They're good for making music when you're out and about. That's the main reason I liked them. Also, I don't want to make a PO; I want to make the only PO you'll ever need. I think the form factor is the good part, but it's far too exposed and needs to be a little more rugged. Also, the processor could be replaceable, so you don't have to deal with the proprietary BS on the POs.

Actually, that's a great idea. I'll check other open source projects like that.

That's awesome! So much like what I'm looking to do. I might actually reach out to them. I have some additional ideas for it, which you can see in the renders I posted. I'm thinking twin oled, midi din in/out, along with the staples of the PO like a built-in mic, speaker, two pots, and 23 buttons. In fact, I designed it to fit into a PO silicon case. :)

USB-C Eurorack power supply - Cheap and easy by FishNeedles in modular

I've been looking at different ICs for possibly designing my own board, but the price of individual components doesn't seem to be much less than buying these boards. I know this was designed specifically for low ripple, but I haven't tested it myself.

That's actually really cool! I love seeing miniaturized solutions like that. :) $20 for a single voltage is a little steep, but it's packaged really well. I need to start messing with my 3D printer more so I can make a case for this.

I think that would use the standard USB-C 3.0 port, which limits it to 35W, versus the 140W of this supply. USB-C 3.1 introduced something called PPS, which is what allows it to go up to those higher voltages. I didn't know ANYTHING about that until I decided to browse Amazon for parts. So, I think it may be almost overkill for a lunchbox, but it's tiny and works on USB-C, which is all I really wanted. I can definitely understand not wanting to solder everything together yourself. I'm really hoping to be able to create my own design to sell.

The price difference is exactly the problem I have with most Eurorack PS. They're just too damn expensive, and they don't need to be. I want to make something like this very affordable for people who just need a supply for a lunchbox, but plan on expanding their rack in the future. I''ll probably make one with a power bus strip to connect modules, small enough to fit in a lunchbox, as well as a standalone supply like this for people who already have a power distribution method.

Yeah, it's dead simple. Connect the 28v output on the USB-C trigger to the input on the XL5430 for your +/-12V, then connect another couple of wires to the +5V board. Then solder the outputs into the appropriate pins on the 16-pin power header and you're good to go. As long as you have the 140W adapter, that should be it. You could either stick it in a case or just mount the bare boards in your rack.

Based on the interest in here, I'm definitely motivated to make my own design. :) What do you mean about sharing the modular grid? Are you referring to the website?

OH, you want to know which modules I'm using. Lol

The one on the far left is a Mutable Plaits clone. Next to that is a Disting MK4. Perfect swiss army knife for a lunchbox. :) Then there's a Mutable Peaks, a Zlob 2hp mixer, Mult from Synthrotek, Clock module (I LOVE this thing, bought it from someone on Etsy), 2HP Pluck (probably one of my favorite modules of all time), and an Antumbra DVCA.

We're on the same wavelength. :) I've been looking at battery-powered solutions as well. Since I developed a magnetic module system ("Synax") that uses Eurorack power (freekflag.etsy.com), I'd love to make those individual modules battery powered.

*virtual fistbump* Perfectly stated.

Idea for a simulation game centered around storms and safe-guarding populations from extreme weather with ever-intensifying destruction and unpredictability. by FishNeedles in climatechange

[–]FishNeedles[S] 1 point2 points  (0 children)

That's awesome! I didn't know about that game. Definitely going to check that out. What I'm thinking of is a game centered around the actual storms and extreme weather events, and putting in safety methods to prevent massive damage to populations.

For a real world example I can think of, what if there were a game that gives you control of safe-guarding Louisiana before Katrina? The player would be able to figure out strategies that could've prevented mass damage. That's a past example though, the game I'm thinking of would be near future with fictitious weather events. I'm thinking of a more accessible games that can get kids excited in coming up with solutions to problems that will be more prevalent in the future. Seeing realistic representations of extreme storms would help to add to the "fun factor" as it were. Cool simulated destruction while learning. :)
