Do you have a name for your SSMH? I was thinking you should call it the 'tubefish'

I agree. Would love to hear it at the NYC meet. Beautiful work.

Haha not yet no but it does look somewhere between a fish and a boiled sweet!

My first build:

Clearly a Mini3, but there's something odd about it...

It has 2 inputs, and they're on the back.

Nothing particularly special, just a high-performance Mini3 without the battery charging circuitry. As you can see, vertical space is a little tight.

Thanks to this guy. A simple little 2-channel active mixer I put together. The parts here are very plain, just TL072s in fact. I figured that since I wasn't going to be working them very hard they should probably do the job, not to mention being cheap. A bank of 1uF Metallized Polyester caps provides for AC coupling, since I don't trust one of my sources (A Zotac MAG nettop) which gives me 50mv of DC offset just to start with. Longer term I plan to build a DAC for it, and maybe my laptop as well.

In reality the mixer was the main motivation for the build, since it ends up being a bit more convenient than my previous approach of running a pulseaudio server on my laptop when I want to watch movies on my nettop (which has hardware decode). It's not like my cans are anything to write home about or anything ( Razer Carcharias ), but they are comfy and durable.

PS- Please excuse the poor photos, all I had available was my cellphone.

another case update (major one) for my beta22 and arduino 'volumaster':

I had some very good help from 'oneplustwo' (jason) who has a pretty neat woodworking shop at his place

he did the cutting on the 2 end pieces as well as the MDF base. we also made a slide-in top but its not vented yet (top will have holes and mesh/screen to let heat out). for now, it runs topless

the bottom base is lined with plastic ABS, as is the front and back panels. I had TAP plastics cut some dollar panels for me and also do the 1/2" radius on the corners. the round holes for jacks were done by me.

features: the arduino (half of an LCDuino-1) controls the IR receive (that's the red jewel-like thing on the front panel, 2nd from left) and sends PWM voltage to the motor pot. the arduino also does the latch control for the front bulgin pushbutton (that $25 button!). it debounces the button (won't let you press faster than once a second, for safety) and also maintains the latch for the relay and the led color (the bi-color led in the bulgin goes to blue for speaker-out and red for phones-out; yes, its an output selector). you can also change the output selector via the IR remote control.

naturally, there is a nite-mode where you can turn all lights out (on the front panel). the IR remote controls this, too.

oh, and the volume pot has a led in it that I (laboriously) mounted myself. took a radio shack knob (sorry!) and drilled a hole thru it, then opened up some room in the back and hot melted a led in there

ran some wires thru a hole in the front (right above the pot shaft) and that goes to a PWM signal that my arduino sends out. when you vary the volume, the led blinks but can also be dimmed if you want. when you turn the lights out, the blue (or red, if phones-mode) light and the knob led both go out.

I will have this with me at the bay area meet, coming up in one week.

I really like the casework, but why ABS and not aluminium?

Nice features with the arduino!

ps: you could build a cmoy with that pushbutton! LOL

I did not need another metal base (and I didn't like the shine from metal on the base)

the backplane has all the grounding I need. its pretty hum-free.

the base is MDF wood and that looked ugly. a very thin (dressing only) sheet of abs helped with visual contrast (imho). and its very very easy to work with.

btw, firmware is at: http://www.netstuff.org/mvc-master/f...r_1_10.pde.txt

I think his comment was more in regards to the faceplate and not the base. I think your response speaks loudly about your priorities in your builds

A really nice build! so amazingly neat! would love to see some nice aluminum panels mounted on to the wooden case. Great work!

Nice i want one! Beats my cmoy in my altoids tin.

More details and images will be posted in the Bijou thread. My Bijou follows the 'Regal Mod' BOM, 410µF photoflash output caps bypassed with 1µF Obliggato golds. I used Solen polypropylenes for C1. The attenuator is Alps RK40 and all signal wiring is shielded. The sound is as good as advertised - lush, lively and grand.

Wow, love this amp! I'm really tempted to make one, must complete my aikido amp first though.

oh, I didn't catch that.

I might replace this with alum. first, we prototype and live with it for a while

if that passes, then we can see about throwing a c-note at FPE or equiv.

I'm not sure I like the jack placement, though. its logical and wire-route optimized but the phones jack placement seems 'off', to me. not sure if I'll keep it that way or center it next time around.

also, this was just built in the last week and so I had no time to do FPE things; and I wanted this to be done in time for the meet next week.

My original front panel design had included a thin white inlay around the outside perimeter of the panel. My wife suggested I illuminate the border instead. (She strongly recommended I publicly give her credit for that idea! Thank you sweetie )

Wow! amazing build! The insides look so neat! Good work!

linuxworks - looks good! I actually quite like what you did with the plastic panels as a short term fix. Also, for the top, as I was looking at your semi-finished product, it occured to me that we could do a solid wood top that has a rabbet to go in the groove that also allows the top to be flush with the top of the sides. It would be much cleaner this way compared to how we were thinking about it before. Also, this would get us out of the 1/4" plywood issue as we could use 1/2" and be less worried about tearout problems while making the vent holes. Solid wood is an option as well although it would be pricey. (Or solid aluminum for that matter.)
