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 skybreakr@gmail.com

There is a passive mixer aimed at DJs with a 3 band EQ, im blanking on the name though. Prof or starpause would know.

This is 2 band and USB powered http://www.musik-schmidt.de/gb-Ik-Multi … g-MIX.html

Analog style MIDI step sequencer!! Id love to be able to program synths with an easy to read/manipulate phrase/pattern sequencer!

one stereo send is plenty, you could even have one of the channels be the return channel, and use that for the makeup gain. Id like to see 1/8th inputs and balanced dual 1/8th trs outputs to keep the size down. So im thinking three stereo channels, four if you are feisty with the three band eq.

Id use this with a gameboy, a caanoo, and maybe a small synth.

Not possible without software support.

What about a Keyboard for Nanoloop, like the LSDJ keyboard? :3

I would say one stereo fx send.

ideally in my mind such a mixer would have matching XLR and TRS balanced outputs. If the form factor only allows for 1/4" outputs they should be balanced so the board can work without a DI box at all.

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

Its all the routing configs that make that particular unit so appealing to me.
What I'm actually envisioning would essentially be a flat tabletop patchbay with a headphone amp and some pots.  Then you could configure it to have many different combinations of effect loops, inputs, and sends.

Sort of like the "monome" of mixers.  lol 

true.

being a low level tinkerer, i couldn't imagine building a mixer that can do better stuff than the 1002b in a reasonable form factor.
but on the other hand, i just hate smd and double sided pcbs.

actually, i'd love to see this done and me be proven wrong
may put an end to my dreams about step-up-converters and car batteries...

also, every mixer in the world needs MOAR EFFETCS SENDS!!!

egr: THAT thing CAN be done cheaper, i'm sure. Looks like 4 pots and 10 jacks in a box for 50$...come oooon

Have a look at the Samson Mixpad 4. I haven't used one, but I'd go for that over the Behri.

Requires 3x9V batteries. 3 band eq etc

Something functionally similar to this but with a more friendly layout would be ideal for me (totally passive so no batteries but probably would need a headphone amp):  http://www.sweetwater.com/store/detail/SplitMix4

You dont build a mixer cause itll be cheaper, you build it to be more useful . I dont think he'll be able to undercut china sweatshop prices.

^ that has mic pre-amps, which cost money to make and take up space, but otherwise its close to what im talking about... figure the size can be reduced but cutting the pre-amps, dropping it to 4 stereo channels from 5, move the input & output jacks (besides headphones) to the rear panel & use knobs instead of sliders for volume... top surface would be down to a 6x4 grid of knobs + a master volume knob & headphone jack, rear panel 10 1/4" jacks and a barrel plug for optional 9v AC adapter

a decent battery mixer would be cool, but i doubt it can be done better and cheaper than this http://www.behringer.com/EN/Products/UBB1002.aspx with reasonable effort.

only one effects send, but 3 band eq!

what i'd like to have is something like an effects send expander, giving me more than the usual 2 effects sends you find in small mixers. No idea how it could be done, though
