  1. Hola, End of year holidays = build time ;-) Here is a new specialized "form factor" for a MBSEQ, that is based on Wilbas CS PCB and the new STM32F4 board. Of course, it involves a bit of DIY to achieve the flatness, some connections have to be soldered without IDC connectors, and U-shaped aluminum rails have to be cut, but no problem! :-) Tech specs: * "Slim and wide" MBSEQ V4, only 21mm high, about 70 cm wide * 40x2 OLEDs for high screen update speed and low power consumption * Pushable encoders for accelerated scrolling/note input * Battery powered for high mobility and no necessity to carry around a PSU for a jam session with friends * High quality omron tactile switches for a few million cycles (at least that is what they are advertised for) * Green transparent acrylics base and side panels for ambient light gathering and green beam emission :-) * Additional bling and functionality achieved with the TPD board :-) * Laser engraved Manga, that has been "inked" for a higher contrast :-). More pictures will be added, as the build progresses, but so far things are looking good! The battery is a 6 cell 2700mAh AA NiMh soldered pack, that can be recharged with a simple wall charger (the charge port is installed in the upper aluminum rail). A small integrated high-efficiency switching PSU converts the 6 - 9V from the battery pack down to a stable 5V. USB powered operation is optional and switchable. The battery actually lasts for many hours, i have not managed to drain it during the assembly test time, I guess it should be good for at least an evening of jamming, but maybe even 10 hours (current not measured, yet). Using NiMH and not LiPo batteries was a requirement, due to easiness of charging and battery safety. This unit was especially built for use on a MIDIfied piano. It fits perfectly on the central noteholder and after attaching just 2 midi cables, one is ready to jam :-). The amount of MIDI ports has been reduced to 4, as more is not necessary for that usecase, but an additinal four MIDI ports can be stacked on top (right side of the unit, see a picture, that is posted later on ;-)). If you are interested in the Formulor/Ponoko plans or have general build questions, say a word, and I will make them available publicly and give advice on how to build it. Hopefully, you are enjoying the report and maybe get some ideas for building a non-standard SEQ? :-) It is the best hardware sequencer on this planet and deserves some customization efforts to create a unique, personalized unit! :-) Many greets, Peter
