In the beginning of this year I decided I was going to finally build The Sequencer. I built my first MIDIbox project 4 years ago, a stereo MB SID, and have been hooked since. Next to my kids, this is the greatest thing in my life, I love it. There's so many great tutorials and tips on the forum about building the SEQ V4, so there's not really a need for another one, but I thought I'd share a few things I did in my build. I used the STM32F4 based Core, with the now available PCB. To save some space in the case, I moved and removed some parts. Removed the jack and the button caps. Cut the buttons and some pins. Moved some pins to the underside. I used the Kyocera LCD's, and read a tip by Altitude about the back light. I omitted the transistor and the resistors, put in a bridge and a multiturn trim pot. Like sometimes at Mouser, the part doesn't look like the picture, but it sort of fits ;) I wanted the max MIDI OUT's, so I used 2xMIDI I/O and 2xQuad IIC boards for 12 OUT and 4 IN The PICs on the second Quad IIC board needs a modified firmware. Tim AKA "Not Mike" AKA SmashTV has it now, but if you want to burn it yourself, it's downloadable further down. The rest of the build is pretty standard. Wilba PCB, Schaeffer front panel and common parts. The case is laser cut acrylic done locally. With the mods on the Core, it's only 4 cm. high :smile: While I was at it, I built the BLM 16x4 and TPD as well (FPD file further down) The last piece was the tinted windows on the TPD, and they really look great I think I am very happy with it, and it's so much fun to play. Thank you TK for everything. Thank you Wilba for the PCB ++ Thank you SmashTV for your shop and service ++ Thank you ilmenator for the BLM and TPD, and the "bling" and of course thanks to the rest of you for all the help, support and inspiration. Beers all around edit: I thought I could buy you all beers, but it's only TK that has a working link Wilbas redirects to a Rick Astley video :), and the others don't have one oh well Cheers Hal iic_hack.hex TPD+BLM_19.fpd

I just made a new version for the AOUT_NG Module with SMT compoments. I made it with Altium Designer. Can Accept Voltages up to 18V. Smaller PCB with height: 6.9 cm length 5.8 cm. All compoments are SMD type exept the Headers. All resistors are 1% tolerance. Murata Trimmer Resistors. All Capacitors are Panasonic. Teardroped Pads and Power planes are carefully designed. Here are the Schematic and PCB Design for Altium ( Custom Library of the compoments is included ) AOUT_NG_SMT.rar Also 2 pictures with the pcb in 3D mode. ________________________________________________________________________ You can build your own DIY Reflow solder oven and make smd reflow easy. Here is a link for the one i use and is perfect. http://andybrown.me.uk/wk/2014/05/11/awreflow/ ________________________________________________________________________ Best Regards Tilemachos
