A bit of minimalist droney piano stuff. Quite lovely if you like that sort of thing. https://vantzou-harrison-bennett.bandcamp.com/album/christina-vantzou-michael-harrison-and-john-also-bennett  

Finally the PCB's arrived for the Kiwi Ears headphone drivers: Just three different PCB's needed, on the left is the diaphragm ring which is a 0.6mm pcb but with no solder mask so it is actually 0.51mm.  This has to be ENIG to make it completely flat but most fabs require that anyway.  Film is 2um mylar-c as that is so simple to get and relatively easy to work with.   In the middle is the dust cover holder/spacer.  I made this 1.6mm thick as that way it clears the stock lip on the baffle that was around the dynamic driver.  I used the first one as spacer and then stacked up the driver sandwich.  For the dust covers I used the same mylar as the diaphragms but not stretched as much Finally the stators, 1mm ENIG pcb's and this is the outer side with the inner side having a smaller active area, aka like the SR-007.  Holes are a bit less than 1mm but that can easily be altered for another run.   Here they are assembled with the only alterations to the baffle where I counter sunk the mounting screws.  There were just the three holes there in a row and with the earpad mounting plate being flush to this, it had to be done.  One second with a counter sunk bit will do this as this is nasty, cheap ABS plastic.   Here they are assembled.  Only mods to the chassis is that I enlarged the two holes there are on each side (cable entry and a port on top) to 5mm so the strain relief would fit and the solid plastic plug I glued into where the port is.  The cable is the 6 core silicone wire that can be found everywhere now with a 3D printed Y-split and Stax plug made from an XLR plug and pins.   Now for the sound... lets just call it work in progress.    This is very much the first draft and one channel is slightly weaker than the other (I swapped out the diaphragm for another which fixed it mostly) so I need to look into that.  I'll probably just build a second pair of drivers so I can match them into pairs as I have another set of the headphones.  Massive baffle leak too and the housing... has issues... so bass is not their strong suit for now.  That needs to be fixed but I might have to get creative with that.   Still for a cheap project that took only a few hours to make and cost less than 150$ all in... there are worse ways to spend an afternoon.  

A while back, I bought a lot of camera gear because I wanted one specific piece.  The lot was cheaper than the item on its own, because eBay.  Included in the pile of gear was a Tamron "vacation lens" (all-in-wonder, not good at anything) 28-300mm F/3.5-6.3 Di VC PZD A010.  Yes, that's its name.  I was not expecting much with the Tamron and it's barely delivered even on that meager promise.  With that said, I did have some fun with it.  This past September, I took the 5D IV and Tamron for a walk around downtown EDG. This New Beetle is parked in front of this shop all summer.  78mm @ F/9, 1/200.   Old Beetle!  It made genuine air cooled noises, and belched out noxious exhaust fumes.  87mm @ F/8, 1/200.   The main drag, which is one way, because it was built for horses. 70mm @ F/8, 1/200.   Zoomed in on the same, 179mm @ F/7.1, 1/250.  Main St. never meant to hold a Wagoneer.   A rather famous boat, with Chappy in the background. 28mm @ F/10, 1/320.   Speaking of famous, the Dolphin returns to harbor.  71mm @ F/10 1/320.   Both On Time ferries, 109mm @ F/9, 1/320.   A Series III on Kelly St.  That's a pet pickup truck I see in the summer behind it. 195mm @ F/7.1, 1/200.   The line for the On Time, Daggett St. 97mm @ F/8, 1/160.   Mose St. is two way, and has parking. It's even less suited for Wagoneers. 97mm @ F/8, 1/200.   The Connaught House, now just another goddamn rental.  109mm @ F/8, 1/250.   North Water St.  179mm @ F/7.1, 1/250.   A cute MG and absolutely garbage bokeh.  223mm @ F/7.1, 1/320.   South Water St, which I have callously ignored for 20 years now. 87mm @ F/8, 1/200.   September is still vacation for some. 43,mm @ F/8, 1/250.   The Tamron is not a very good lens.  It covers a large focal range and not well.  I had to work over many of the above pretty thoroughly to get decent results.  I also had a bunch of shots that were not really worth the effort to salvage.  Tune in next time for Vineyard wildlife and some seasonal colors.

Jumpstarted the holiday cheer (winterless necessity) with a trip to lights.
