@dsv101 - Haha, thanks. This project has been ongoing for quite some time, I just have been busy with other things.
@Krubbz - Thanks, I'm glad people are interested in this.

@threesecondsecret - At the moment it is planned to have 4 stereo channels, but if people end up wanting to cut costs, it would be fairly simple to lower the number of channels.

I've posted a design mock-up for the mixer on my tumblr
Check it out here:

@infradead - The jumper cables would probably be easiest for configuring the mixer, but my only thought is that you would still have to have all of the modules present in the mixer itself, regardless of whether or not you are using them. The way I envision it is having separate modules that would fit together in order to reduce the components needed for the mixer, meaning if you only need a mixer with no EQ or FX sends then you would only need the base mixer module and none of the others.

@Auxide, Downstate, and herr_prof - Thanks! I'm glad that people are interested in the whole modular design thing, I'll try and get some sort of mockup done soon, and I'll work on getting a prototype built as soon as I get the parts for it.

@KeFF - Thanks!, I thought it would be nice to allow people to configure the mixer to their needs somewhat.
@BTS - I think it may be fixed at 3 or 4 channels, but if I can figure out a good way to do so I suppose its an option. As far as connecting the modules goes I was thinking about having separate modules that connect via a bus that provides power and connects the audio signals as opposed to having them joined with audio cables, but all of that is still up in the air

Hey everyone,
Awhile back I came here to get some ideas for hardware projects and a battery powered mixer was something that a number of people wanted. I've basically gotten the design finished for said mixer and hopefully will be able to breadboard the design once I get some parts, then a full prototype, and then maybe a custom PCB + enclosure deal.
I got thinking about one thing the other day though, would people be interested in a more modular design? What I mean by that is that there will be the base mixer module and then you can plug in an EQ module or an FX send module into each channel and expand the mixer capabilities that way. That way for people who just want a cheap mixer with no bells or whistles can have that, but others have the option of adding things to it to suit their needs. I may need to rework the design to deal with power routing to the modules and such, but if people are interested I think it could be pretty neat.
So let me know what you think, and if anyone has questions I will do my best to answer them here.
Cheers

Hey everyone,
I haven't fully started working on anything, just kind of poking around until I have free time over the summer, but I just wanted to give a really quick update:
FOR ACTUAL PROJECT UPDATES I WILL BE UPDATING THIS SITE (SEMI-REGULARLY) -> http://skybreakr.tumblr.com/
>> Started on the mixer design and I'm using a design from the All Electric Kitchen as a base (http://all-electric.com/b&c.html > Simple Mixer Circuits)
What it looks like its going to turn out to be is 4 (3 if the design gets too complex/expensive) stereo channels (1/8" trs), all with a 3 band eq (low shelf, high shelf, band), each channel is also going to have 1 stereo fx send. Then the whole thing is going to be output to a stereo TRS jack (maybe 1/8" just to keep it consistant with the inputs) and possible a R/L RCA pair. The headphone jack is just going to be a 1/8" trs as well.
>> I am currently looking into an internal video out mod for the DMG and I talked briefly with NeX about it.
Its going to be a tough one.
I have to get my hands on a FPGA board and try and replicate another persons project before I try and make something small enough to ram into the case, but all of that will hopefully come in due time.
I tried to read through the entire thread, but I didn't take notes about all the different ideas people had and kinda forgot/been too busy to really read through it, so if anyone has any questions or ideas, w/e just send me an email at [email protected]

Re: Hardware project ideas (35 replies, posted in Other Hardware)
So it seems like the battery-powered mixer is a crowd favourite at this point, and I did a bit of thinking on it, and here's what I came up with:
- Using a passive mixer, so there will be no amplification in the mixing stage and you will still need to amp the output, but I'm not sure how well that will integrate with the fx sends and such.
- 4 stereo channels with fx sends (not sure how many, most likely be 2 to keep it simpler, sorry guys).
- Headphone out, nuff said.
- 3 band eq = to keep it simpler, I think it will boil down to having 3 set filters with adjustable frequency and gain
**What would people find the most useful?** (Was thinking maybe a low cut or shelf, a bandpass, and then, I dunno, maybe a high cut?, its really up to the majority)
- Then for the output do people want a 2 jack, L/mono & R type deal, or other outputs?
Also, What inputs would people like? I'm thinking the standard 1/4" TRS will be popular, but I'm not sure what people want.
Finally, what range of devices are people going to use with this? (should it eventually come to fruition), just for reference

Re: Hardware project ideas (35 replies, posted in Other Hardware)
Hey everyone, thanks for the great suggestions.
I'm going to do some research into this stuff and then a bit of brainstorming and I will see what is
going to be the easiest to design and probably start with that.
That's not to say I won't get to the others, just what gets attacked first.
EDIT

Thanks, I kind of blanked on the title.
Also on the battery mixer, how many inputs would people be looking for? Is the idea just a small portable mixer that just does the basics? Also what special features would people like?

Topic: Hardware project ideas (35 replies, posted in Other Hardware)
Hey everybody,
I'm looking to maybe take on a couple projects this summer and I was wondering if anybody had any ideas for hardware they would like designed and built.
I want to build something, but I'm just having a hard time coming up with ideas.
When finished, I'm thinking that I'll just release the design as open source and make all the circuit designs and such publicly available to modify, build on, etc.
So what kind of stuff do people want?
