This project is a simple yet useful audio tool.
It's easy to build, the parts are inexpensive and Through Hole Terminal only, so if you're a beginner, it's a great opportunity to learn how to solder.

I got my Stereo Pots, Trimmers, and the resettable Fuse from here:

This is perfect for a project I have in mind. Thank you for sharing this!!!
thank you !
Amazing what can be done with skills and brains. Thumbs up
thanks for subscribing !
Very cool
Hi ! Nice project. I'm gonna give it a try. I'm thinking to modify this and make it a 3 channels mixer.
Cool idea!
Same question for the trimmers. A link would be great. Thanks
This is so awesome! Been looking for something like this for a bit and I'm glad that I was able to find someone else already attempting to solve the problem for themselves as quickly as I did! Thanks for showing us how we can make our own. I'll be using this to create my own mixer, for sure.
I have a couple questions about some of the circuit. I'm wondering if you might be able to answer them for me. Are the caps C3, C14, and C28 to C33 totally required? They seem to be filtering AC out of an AC signal, which doesn't sound desirable to me. I'd imagine you'd only ever want to have these caps in series with the signal so as to block the DC, but maybe they're doing something I don't know about. Also, I've seen R-C configurations like what are on the outputs of each channel's amp (the caps and resistors in series to ground), but I'm not sure about what they're doing. Seems a bit different to the other caps that are by themselves.
Thanks again for making your project public. I'm sure this will help out a whole lot of people.
This is great !!! Can you tell me where can I find the exact type of stereo potentiometers you used ? Thanks for sharing
Thanks ! See the pinned comment.
@@coreWeaver thanks for posting the links. I guess anyone building this project will also finding useful
Sounds very good. Id like to make one for my desk with two pcs and a single set of speakers. I'm pretty new to electronics though and choosing the right components to order is very difficult. If I order from Reichelt to get same quality result, does anyone have a list of item numbers please for the order?
please see my pinned comment for the pots, trimmers and the resettable fuse. Those are the exact ones I used. All the other parts are non-critical. The resistors are 0207, metal film, 1% tolerance. The electrolytic caps should be rated at least 16V. 2.5mm raster with 5-6mm Dia. should be fine. As for the audio connector, I used the PJ307. The color is not important. Let me know if this helps and please don't forget to subscribe.
@@coreWeaver It's the other components I struggle with, the caps especially. When I get on site it's like a sea of caps. Would it be possible to help out please? I'd happily pay you for the use of your system you designed.
@@garyseaman6105 I made you a list. Send me an email: core.weaver@gmail.com
Hey! This looks like a really awesome project for an item I would get a lot of use out of. I am new to custom electronics, and having all the resources and time you have put in makes this seem very approachable.
I was looking into getting one of the PCBs made up so I could try this, but I am having issues with the files you uploaded, mainly that there does not appear to be a board outline or drill file included. Am I making a newbie mistake or are they genuinely not included? Follow up to that question: what CAD software are you using to create the files? Maybe I could create my own board design based on your specs!
It looks like the drill file is the .txt file in the zip file. I've seen this once before, but I haven't ever tried to have a board made with this format of drill file so I can't really help much more than that. But hopefully that steers you in the right direction.
Also, to answer your other question, it looks like they used EAGLE. But they didn't include the project files in the repo they linked to, so you'd have to recreate the board with help from viewing the schematic and gerbers.
Buy LM386-4 to get a FULL Watt out.
Hi, i want aim assist, but i want to use keyboard and mouse. Should I go with esp32 s2 usb host, or should I use ch559 combined with other microcontroller esp32 s2?
This is just for getting the sound out and mixing it with your own music
