It's been a while since I posted, as it's been a while since I've been able to work on the MB6582. I've been waiting for parts to come in (namely the LCDs from China.) In the meantime, I replaced all the SMD capacitors on the logic board of an old, non working Mac Classic II I had bought on ebay for a song. It actually works now! I'm gaining a little confidence. (Look out!)
So, I took all your helpful suggestions to heart. I made a new LCD cable, attached the connector, and tested all t
:sorcerer: :sorcerer: everything ready for the order
the big 3mm Acryl multipanel + 3mm MDF Base + 0,5 mm PET panel for the displays will cost 65 €
- i think thats a fair price for so many parts :frantics:
edit . pic2
now its time to wait for them.....( and to make the missing cut-outs for the display, the buttons and the connector on my Mixer)
Hi!
Today I got my membrane-Potentiometers (100mm-Hotpot) from Watterott. I had to wire a 10k resitor to between the "wiper" and ground. If this is not done, when the membrane is not touched it, and therefore the AD-converter-input, doesn't have any scecified contact with ground or 3.3V so it will send random signals, which cannot be filtered. With the 10k resitor, the value will be zero when the membrane is not touched, but this can easily be filtered by software.
Like this the pot works qu
I have finished all Parts for the Midi-Mixer
but now i have to wait for the Faceplate/Case <- gone for Sandblasting and Powder Coating in white.
So have started the rebuilt of the Sequencer V2 (and upgrade to V3)- have bought it in the Forum. (thausand thanks to Alex!!! )
First i have testet it and than desolderd everything into basicparts.
- 2 Lcd's
- all Pcbs (the Core V2 will be replaced by Ultracore-Pcb with 2 II2c Midiouts)
- nice buttons and Alps Encoders
- from a T
Yeah, after evenings of soldering ist done!
I'm still a bit unsure whether I should have done some of them on vectorboard, but like this, I can attach my modules directly under each button-cluster.

Today I etched a few more PCBs. Now the control surface is complete. Or that is - I haven't yet soldered on most of the cables on the new boards, but components are soldered, backlight on the menu encoder is tested, ok (looks good as expected hehe) and I laid it out on the workbench to see how I want the frontpanel to be. I think I'm gonna use this setup here, unless I get any bright ideas or any bright tips :).
It has 8 general purpose encoders, 8 general purpose buttons, encoder for left/ri
Today the nylon spacers arrived, yesterday the smd leds arrived. So I etched the upper board, drilled it, soldered the LEDs sandwitched it all together and tested the leds with some normal resistors. I haven't yet ordered the smd resistors that is going on this board, as I am searching for them on ebay - as soon as I find the right ones, I'll get to them too.
But at least I got to test the board. Have a look :).
Looks nice yeah? :D I am very pleased with it so far ;) (sorry
My next job was to tackle the LCD.
I think I made a few mistakes, the first being the fact that I didn't take enough pictures.
I made my cable. I crimped on the 10 pin connector to the ribbon cable, no problem. I did my tests and it seemed ok.
When I started soldering the ribbon cable to the LCD, I think I did them upside down. It was odd, because I was trying to match the picture (photo 7 on step 12) on the tutorial, but I noticed the little arrow on the connector that I thought w
It's been a minute since I posted... I'm sure you've missed me.
I made some progress... then I hit a bump in the road. Then, some work came in, and thank goodness for that, but it's eaten into the time I'd rather be spending getting this synth project finished.
Anyhoo... the progress. (I'll put the bump in the road on the next post)
Here is the front panel with the tactile switches:
I made a mask with the cardboard that came with my front panel:

Yo!
Just thought I'd do a small blog entry on the sideproject (I consider the synths my main projects). A midibox 64e. This is a short term project, and all parts have arrived or are on their way. It's gonna have 9 encoders, lcd and some buttons + 4 expression pedal connections. One pedal is soon built - waiting for the last parts to arrive from the states :).
Anyway, some of you might have seen my picture of the encoder PCB. Now, here is a couple of pics of the finished built pcb. Also fi
Today I tested a infrared distance sensor.
I am using a Sharp2d120x, with a range from 4-30cm. I soldered its ground and source to J2, as the sensor
requires 5V to operate, and its output (analog voltage proportional to the distance) to an analog input.
The sensor works quite well, except it cannot reach the highest 5% of the midivalue, but this is not a
problem for me.

I had painted the wooden case for my controller, and it finished drying today.
I used "Dekorwachs", it needed a long time to dry completly. The water- and dirt-repelling properties
of wax are really good. All in all I am quite content with my build, still there are a few quirks with
the case, like minor gaps due to the wood (spruce-wood tends to "work") and a small break out where
the usb and power plug will sit. Well one has to learn by doing...

Patience was never a strong trait of mine, at least when I'm obsessing on something. This MB-6582 project is certainly my main obsession right now, and I've run into another snag that I can only blame myself for.
I was not expecting to be able to get any work done last night, but the opportunity came up. So, I started putting in the tactile switches into the CS PSB. When working on the CS, I'm following Hawkeye's amazing thread. I rocked step 6 while in a zone of meticulousness and aware
My electronics "lab" has now been moved out of the laundry room and minimally set up in another nook in the basement. Still yet to see if the landlord approves... :ahappy:
I got it set up in time to put a couple hours of work on the base PCB. I had picked up some 1K resistors at Radio Shack to replace the ones I destroyed. I picked up 1/2 watt resistors, thinking that was the right rating. However, bringing them home, I see they are much bigger than my original resistors were. I'm a
Hi!
As I only started blogging, but work on this controller for about a month (plus some planning time), I have to close up to my current status, which I will do today.
So the controller is called mothership, because it is rather big :rolleyes: . It will be around a metre to half a metre to fifteen centimetres.
It holds controls for four decks inclusive jogwheels, four-section (midi)mixer, an effectsection plus loop-recorder controls. And some other stuff I found very funny, like infrar
My next step was to build a working core (lpc17) with some DINs and DOUTs. After some troubles ... I succeded.
I am really astonished, this device is the least troublesome device I have encountered so far. No extra drivers, just plug and play, and the controller can be unlugged and reconnected while traktor is running, no crash, not even a lag!
By the way, the midibox-site is really awesome and must be really a lot of work, so thanks to everyone and especially Thorsten!

Hi,
this is my blog about how I am going to build a Traktor-Controller.
Well, and if this one turns out good, or at least not too bad, building more controllers.
I am playing around with traktor for about two years, and I was never really satisfied with the layout of the (traktor, or other midi-) controllers one could buy.
Thus, when I found the ucapps site about half an year ago, I really liked the idea of building a midicontroller myself, but I was not really sure, whether I was capable
So, a little background:
I have been doing my work a temporary lab I had set up down the basement of the building I live in. It's actually in the laundry room. I get in the way of the landlord trying to do his laundry, and I'm ducking under drying jeans just to get to the table. I know the moisture in the room isn't ideal, but it's what I got. If you know anything about living in NYC, space is at a total premium, and just to have access to a basement (esp without owning the bldg) is a ser
So... After a morning session, a 5 hour rehearsal and 2 hours working in my studio, I was able to sneak into the basement lab to do some work for a short spell.
Here's the board yesterday after I yanked... uh, carefully took out those resistors I had installed incorrectly... It's the R4_SIDx and R24_SIDx series that I had put into the C3_SIDx/C23_SIDx spot. (I stole, er, borrowed my wife's nice camera, so these pics are a little more detailed)
There was still leftover solder in s
Here's a recap of my first week building my MB-6582. Pics were taken on an iPad. I love my iPad for a lot of things, and it's camera is definitely not one of them.
I got my parts (so nice...so shiny) right before I had to split town a couple weeks. Once I got back, I was rarin to go.
Everything started off pretty smoothly. I was being vigilant about following the construction guide. So I started with resistors, diodes, and caps that were inside of IC sockets. Although I didn't notice th
Greetings. I'm starting this blog as a record for myself, and also to keep from pestering everyone constantly on the MB Forum over all the details of what I'm doing. Even though I think it's incredibly exciting, I'm still in an orbit deep within the galaxy of Noob, you dig. It's probably not that interesting to you kids out there with mad electronikz skillz. Perhaps my experiences will be of some use to someone else taking the plunge into this world, but I'm not holding my breath. I'm proba
