Deckard's Dream DIY (Part 4)

 The last board I had to do is the Hardware PCB. This is basically the 'human' interface of the synthesizer. It holds all the knobs and sliders and the display. Again the first thing to do is solder all the SMD capacitors. You need to apply flux first if you want the solder to flow under the components connecting surfaces. I have become quite handy by now, but I do need some magnifying glasses to see everything. Age isn't helping me here :) My eyes have been better in the past.

On this board there are also components on both sides. So you have to watch carefully for that. Eventually this board will be hooked up to the Main PCB they will be connected with the two double header connectors you see on the right. I did try if it fitted and it did so I guess that is OK. There are also some resistors and IC Sockets that go on the back side.

And here you see a picture with most of the sliders on there. I was a bit puzzled that some were different values than stated in the parts list, but since they are only voltage dividers it doesn't really matter which value you put in. I'm still looking how the display has to go in. I'm looking for some build pictures of other people for that. But I'm sure I'll figure it out in the end. Next time is actually testing the boards with the lab power supply and see if there are no shorts. First without the ICs and then a second time with ICs and see if everything stars. More about that in a next part.
