Deckard's Dream DIY (Part 6)

Next thing to do was connecting the main PCB to the hardware PCB. After that I also did a quick power test and again the magic smoke stayed in :) I had some trouble determining how to mount the oled display so I didn't solder that yet. There is not much information available unfortunately about the mechanical construction of the Deckards Dream. I did look at some pictures online but still I didn't know for sure. So it was time to also screw on the front panel to see how it all fitted together. At first I had the spacers wrong so that the front panel was too far away. So this is a picture after the second attempt. And now I could also finally solder the oled display.

And then it was time for yet another exiting part of the whole build. Finally putting some software in the Deckard's Dream. You do need to buy a ST programmer for this and connect it a flat cable to the main PCB and with USB on your computer. You can freely download the programmer software. It did see my programmer right away and they you hit 'connect' to hook it up to the main PCB. There is actually a micro controller on the PCB. It is kind of a mini computer that controls everything and it needs software to run. You can download the 'bootloader' software from the Deckard's Dream build page and then you hit 'program' and it actually worked :) I got a success message. After this you disconnect the programmer and switch the Deckard's Dream of and on again. Some garbage appeared on the oled display. But then the manual said to hold the 'shift' button to boot it in USB mode. So I did and then the Deckards Dream acts as a USB drive and you can copy the firmware and factory sound banks on it. Reboot again and voila ! It came alive :) I had a working menu on the oled display.

Here is another picture of the backside where you can see the sandwich of the main pcb the hardware PCB and the front panel. You can also see the correct spot and orientation of the Power Supply PCB in this picture. The only thing I find strange is that all the boards will be connected together in the end. I don't know how yet at this moment, but I'm sure I'll figure it out. There are all hanging horizontally though in the cart-edge connectors without any fixture. So that is a bit surprising to me. But we'll see later about that.

And finally here is a picture of the front of the assembly. Here you can see all the sliders and what they do and everything seems to fit fine :) I also soldered the headphone connector on now. I didn't do that yet again because I wasn't sure about the fit. The only thing missing now is the power switch. I will do that when I assemble everything together in the case.
