loziniak2 Posted February 23, 2009 Report Share Posted February 23, 2009 Hi all!In January I started to build my own seq v3.4. I thought I'll post some info / pictures / files of it, to contribute something, and maybe get some feedback. And I just love to watch others' equipment being built (greetz to Sasha, Gridracer and many others), so I hope someone could enjoy mine too :-)I'm building it entirely of parts available locally (posting from USA is far too expensive, and it seemed like challenge to me. Almost everything I need is available here in Poland, the only thing that I didn't manage to find till now is 512kb banksticks in DIP package, but I hope it'll happen at some time...I'm going to use a Commodore 64C's case. Maybe I'll build a SID midibox one day using it's chip. I'm planning to rearrange buttons a little, so I can fit everything into the 132.5x400mm front panel. Main difference is I'm using my encoders' "switch" function to get rid of one row of switches. The details will follow.The whole welding / pcb / electronics mess is a new thing for me, so I got in touch with one guy who studied and works as an electronic engineer, so he helped me a lot - chose welding iron, recommended some places to buy parts, etched pcbs, and programmed the PIC chip (there were some problems because wi were using non-midibox programmer, see this thread: http://www.midibox.org/forum/index.php/topic,13008.0.html). Great thanks to Grzesiek!Ok, so that's for introduction, if I'll recall some more facts, I'll keep posting. Now the pictures :-) Quote Link to comment Share on other sites More sharing options...
loziniak2 Posted February 23, 2009 Author Report Share Posted February 23, 2009 There is my front panel design - a png picture and a dxf project made in QCad (http://www.ribbonsoft.com/qcad.html). Maybe it will be of some use for someone.Blue lines are holes in panel, which will be CNC-cut. Yellow ones are project of pcbs. And the brown are contours of parts.The buttons are (from left to right and top to bottom):- "all" and "fast" - these will be frequently used I think so I put them easily accessible by left hand.- 4 tracks and 4 groups- 3 layers and 3 triggers- rew/stop/play/pause/ffwd- led bpm display together with beat and midi tx leds- datawheel- two 2x40 lcds- 16 encoders with switch functions (left to right: mute, solo, pattern, song, f1, f2, f3, f4, exit, select, 2x not assigned, scrub, metronome, menu, edit), 3mm leds next to them- 16 step switches with standard menu functions, the one in center is 1-16/17-32 view switch.panel.dxf.zippanel.dxf.zip Quote Link to comment Share on other sites More sharing options...
loziniak2 Posted February 23, 2009 Author Report Share Posted February 23, 2009 Pictures of all the electronics I've got till now, and some user interface parts. Quote Link to comment Share on other sites More sharing options...
Gridracer Posted February 28, 2009 Report Share Posted February 28, 2009 Hello loziniak2 nice to see another SEQ arise! :DI guess you were as happy as I was when reading "ready" on the display for the first time. ;)Looking forward to see new pictures from your project.Good Luck, and Greetings!By the way, did you etch those PCB;s yourself? They look great! Quote Link to comment Share on other sites More sharing options...
loziniak2 Posted March 3, 2009 Author Report Share Posted March 3, 2009 Thanks for your warm words :-) The PCBs were etched by my friend, he's got all necessary chemicals, tools and knowledge. He also helped me to program the PIC, the rest is mine - drilling holes, soldering, designing...I don't have many new things to show, because I'm waiting for my front panel, because it's the main element to fit others to. Btw, I'm very happy, because I found a workshop here in Warsaw that will laser-cut the panel, a few internal parts, and do powder-coating of panel, all for less than 20 euro.In the meantime, inspired by Sasha http://www.midibox.org/forum/index.php/topic,12941.0.html, I repaired my Roland D-5. I changed all microswitches which had some beer or coffee in them and were getting stuck, exchanged damaged 3rd octave of rubber contacts with good 1st octave, and cleaned all the mess that was inside. I could tell the nutrition habits of previous owner from the content of synth's case ;-)greetsMaciek Quote Link to comment Share on other sites More sharing options...
loziniak2 Posted March 15, 2009 Author Report Share Posted March 15, 2009 Some recent pictures.not all encoders are at place, and nothing is wired, but it starts to look like it's supposed to :-) Quote Link to comment Share on other sites More sharing options...

Gridracer Posted March 17, 2009 Report Share Posted March 17, 2009 It's growing up!Just a matter of time when he does his first STEPS.Or is it a girl? ;) Quote Link to comment Share on other sites More sharing options...
loziniak2 Posted April 26, 2009 Author Report Share Posted April 26, 2009 First steps done! Baby is walking like a hurricane ;-) There are some issues to fix, and not everything is finished, but it already speaks to my Electribe. Now I'm thinking about a name...cheers :-) Quote Link to comment Share on other sites More sharing options...
Flexinoodle Posted April 26, 2009 Report Share Posted April 26, 2009 Oh yeah :)Wait did i say Oh yeah :)Really frikkin coolFlexi Quote Link to comment Share on other sites More sharing options...
stryd_one Posted April 27, 2009 Report Share Posted April 27, 2009 Very nice :)I think if it were mine, I would spraypaint the case to match that nice dark grey panel.... I really like that panel :D Quote Link to comment Share on other sites More sharing options...
loziniak2 Posted April 29, 2009 Author Report Share Posted April 29, 2009 Hehe now I'd rather like more to play it than to paint it ;-) But yes, it's my plan - will spray it, probably yellow (like these yellow buttons), dark gray is also an idea, I'll consider it ;-) I'm glad you like it.

Gridracer Posted May 4, 2009 Report Share Posted May 4, 2009 will spray it, probably yellowYELLOW, Yes, ACID-smiley-yello like!Greetings Gridracer Quote Link to comment Share on other sites More sharing options...
