  1. The Sequencer is finally up an running in his new Acrylic case ... Todo's ... adding a 5 Volt external PS for the STM32F4 instead of USB-cable and building the Frontpanel for the Line-Driverstuff

  2. I`m back after long time out of MB community and doing electronics in general. I have quite a few unfinished projects that needs some attention. In most cases it is just building housings and final touches, but still a lot of work. I feel bit rusty now, but I`ll catch what I`ve missed. See you around! ;)

  3. MIDIbox has been a big deal to me, for a long time. While I’ve built a few MIDIbox projects over the years, I always wanted to be a bigger contributor, and there has always been something in my life to stop me. Over the past few years my marriage has taken a big shit all over my life. I find myself with great ideas, only unable to fully realize them because of the amount of trouble in my life, particularly because I just couldn’t seem to get along with my wife. I am not suggesting for a moment that MIDIboxing should be more important to anybody than the sacred institution of marria

  4. When interfacing a Joystick, Modwheel or Pitchbender it is sometimes found that the voltage range on the potentiometer output is well inside the range of the Core ADC input. This can often be overcome with digital calibration in the firmware (e.g MIDIbox KB) in some cases there is extreme loss of resolution. Presented here is a circuit to overcome this to give the ADC the full range (in this case 0..3.3V) even though the range of the potentiometer is well inside this. The design process is very easily done following this app note:sloa097.pdf 230.01K 12 downloads

  7. The missing socket arrived this morning. Full of will power I waited until after the days work was done before getting out the now rapidly declining box of bits. Socket in, C64 PSU tested, 9V tested good, so was ready to go. Small glitch until I realised that I had to change the core ID in MIOS Studio too, then all loaded smoothly. Fitted the 6852's one pair at a time, and ran through the sound banks, with a silly grin just getting wider on my face. Still got a minor bit of front panel work to do, (3 spacers came unglued), and a little bit of fault tracing - the mix out doesn't seem to be

  8. Nach nem sehr chaotischen Jahr wurde die Projektkiste ausgepackt und eine Bestandsaufnahme gemacht. Das Projekt ist inzwischen mehr als 2 Jahre alt aber das ist nach wie vor die Zielsetzung: 3 Sektionen + 2 Extra Encoder (dafür fehlen noch entsprechende Alustücke und die Bohrungen in der Aluplattte 1. Sektion 16 Potis , 14 Taster , 14 Leds Stand : Front fertig lackiert, Teile montiert, 2. Sektion 2 Potis , 11 Leds , 5 Encoder Stand : Aluplatte fertig, Teile montiert - fehlt noch die Folie 3. Sektion 4 Fader , 4 Encoder, 2 Leds Stand : es fehlt noch d

  9. Construction d'un séquenceur, SEQ V4 midibox (2016) http://ksir-diy.blogspot.fr/ Après la construction de 2 contrôleurs midi le modulebox et le pushbox, je décide de fabriquer un séquenceur. Toutes les infos proviennent du site: Merci T.K. http://www.ucapps.de/midibox_seq.html 1ere étape, construction de la BOM, liste des pièces a commander https://docs.google.com/spreadsheets/d/1QeJV0jgEi0ly2ljBv7idEdsqg11bE0XkwrLQFL_UkEw/edit?usp=sharing En attendant la réception des circuits imprimés que j'ai commandé sur : http://midibox

  10. Nothing earth shatteringly different from the normal happening yet. I've just got my (very lovely) boards delivered from SmashTV and soldered them up, so here sit two STM32F4 cores (sans SD card hardware because it's not here yet)

  11. The SIL couldn't be delivered and I had to do the LED twice because of the round buttons, but progress is visible :)

  12. Not much time this weekend But I managed to Solder up a few NEW DIN/DOUT boards. And the complication comes in the pinning of the new boards, the arrangement of the 2x5 header does not allow me to use my old 1x5 cables to the CS as wired in V3, due to the arrangement of the SR inputs. Not a big deal, off to the HW config file to do some editing (It was bound to happen sooner or later!)..... Other observations on the New DIN/DOUT boards....It would be nice to have a bit more clearance to use shrouded (Box) headers, The I/O headers on the end overlap board mounting holes and the SR c

  13. So many years ago I started an MBSEQv3. Life happened, moved a couple times, it sat on a shelf unfinished. So now I begin to upgrade it to v4 and finish it off. below are some pics of it after pulling it off the shelf: The case is an old rackmount Altec Lansing Mixer, I will have a new panel laser cut from acrylic You can see the 4x16 BLM's i started, one is finished the other I forgot to stuff diodes.....(they were made months apart) DOH! board on the right with the cutout in the middle is the transport section, a large jog wheel will go with the encoder shaft through the cutout.

  14. Hy! My name is Nicolas, and I'll try to translate an already posted message in french. Im passionated on MIDI technologies since I was a little boy, even if I understood later that i could'nt connect my joystick to dads minimoog ;) Now Im looking to develop a touchscreen interface to manage different hardware equipments, so I need some peace of information to go forward on this: As Im rather good on Macromedia Flash: where do you think I can find information on how to communicate via MIDI protocols? But I'm a really bad electronician: so how can i find info on to integrate to fantastic u

  15. Hello everybody much time hast past since my last entry here, but this project is not dead. what happened in the meantime? my studies ate up much more time than I planned, so I had to change priorities. but its not all about math and machine construction ;-) first step was creating all the pcbs i need for building the controller and - my very own PIC-Burner. I used his lovely little pre-project to gain some advanced skills for the etching machine at work. thanks to my boss, i got a nice box, LEDs and faceplate for it. next step was the first big order from bürklin (havi
