  1. In no particular order: Finished another roll of film. The first one I put through my Rebel K2 in 15 years(!) Still have no idea where I'm going to get it (and the other three rolls I have) developed. The only photo from my ferry ride back from the mainland that I've bothered to edit. Departing from MV. Those are some very Vineyard weather conditions unfolding. Makes for ethereal imagery. Fussing around with a circular polarizer on my 17-40L. The combination is a PITA to use because I have to adjust the filter with the lens hood off, re-attach the hood and then frame the shot. Testing out my 5D IV the first day I got it. Taken with my 50mm F/1.4, which I hardly use because I prefer my OG 1986 "Nifty Fifty" 50mm F/1.8 in every regard. A young buck across the pond. It is with great restraint that I avoid shopping for Canon 400mm or 500mm L prime. Wildlife photography is where dreams and bank accounts go to die. The contractor working on our house is ...quite a character. He's either greatly over or under medicated for his ADD. He's got a really nice doggo however. Her name is Turkey and she's an English Bull/Boxer mix. She has a gorgeous brindle coat. Watching her dart around my yard put me dangerously close to wanting a dog. A study of the tool shed my grandfather build in the 50s. Futzing with the 85mm F/1.8. Absolute silliness with the 17-40 at the wide end. From my first test of the nutty Suntar 135mm F/2.8 M42 lens I bought for under $20. It has an amazingly long minimum focus distance and an aperture that only increments in full stops. This was taken at F/5.6 or F/8 IIRC. I ran this images through Luminar 4 and applied a LUT to it. Did I mention I bought a Holga HL-C 60mm F/8 in Canon EF mount? It's enormously silly. I got a Asahi Super-Takumar 50mm F/1.4 in the mid 00s, as part of a lot of M42 lenses I bought of eBay. It's quite expensive now. I find it to be reasonably sharp when stopped down, but never particularly contrasty. I post processed the above two photos extensively in Luminar 4 and Photoshop. This is Sweetened Water Pond, which is the one across the street from where I live. It's normally a Vernal pond, going dry in the summer. It stuck around for all of this year and the ducks were quite happy about it. You've heard of Turquoise Hexagon Sun? This is Orange Hexagon Lens Flare. The Takumar's element coatings are decidedly a product of the 1970s. The CZJ Sonnar 135mm F/3.5 once again proving it's the best actual lens amongst the army of 135mm primes I own. Early evening moon. 85mm F/1.8 again. It is a really good lens that I don't use nearly enough.

  2. @jokerman777 I use a 10K trimmer in place of R73 for a forum member's DIY T2 as well, to trim the ~10V offset down to near zero. I know the transistors are most likely not matched on that unit and it doesn't make sense to remove them and match again. In your case the offset is significantly more. I would try to root cause it before replacing R73 with a trimmer. FYI the Vbe of Q33 and Q32 measured on that unit are 0.5xV and 0.6xV respectively. It's definitely a problem if Vbe measures negative. To troubleshoot point C and D, you can temporarily disconnect the 2.2M resistors R80 thru R83. Measuring across R89/91 with a meter having 10M Ohm input impedance only adds about 1% error, so no worries. Check the polarities and short on D29 thru D32. They could pull the voltage at C/D through R80 thru R83 if in a wrong polarity. Once the voltage on C/D correctly reflects O+/O-, the balance servo can still bottom out trying to adjust. Measure the output voltage of the opamps. If they come within 3V of its power rails, I'd trim the battery voltage gently so the opamps come back to the 'comfort zone'.

  3. Even Shelly drank year old Mattnog, despite her phobias! 😆 It's safe so long as it was refrigerated. Wild Turkey Mattnog 2023! And the Bacardi Gold ought to add some more sweetness given the two cups of rye.

  4. Happy Guy Fawkes Night! for those of you not familiar with it, let Stephen Merchant explain! Not Clear? How about a mini-series ? Guy Fawkes ("the last man to enter Parliament with honest intentions") Was involved in The Gunpowder Plot, ( see also https://www.parliament.uk/about/living-heritage/evolutionofparliament/parliamentaryauthority/the-gunpowder-plot-of-1605/) caught, tried and executed for treason. But not just any execution. https://en.wikipedia.org/wiki/Hanged,_drawn_and_quartered His punishment was brutal and specific (as our tour guide in York was more than happy to explain ...) " drawn backwards to his death, by a horse, his head near the ground. They were to be "put to death halfway between heaven and earth as unworthy of both". Their genitals would be cut off and burnt before their eyes, and their bowels and hearts removed. They would then be decapitated, and the dismembered parts of their bodies displayed so that they might become "prey for the fowls of the air" https://fiveminutehistory.com/the-execution-of-guy-fawkes-and-the-gunpowder-plotters-hanged-drawn-and-quartered/ So there you go. Happy Guy Fawkes Night! https://en.wikipedia.org/wiki/Gunpowder_Plot_in_popular_culture

  5. Nice that you guys keep this thread and the Mattnog tradition going. He would have loved this thread. Well, no, actually, he wouldn't have said a word about it. But it would have made him feel good inside to know that you cared that much about him and that you still remember him well.
