  1. So floofy. Not travelling as much for work these days, but still interested in optimization Trying a new means of getting around the airport. At least 14x more fun then I have had in MSP before.

  2. Holy crap, finally got this thing running right after like two years. My last screwup was actually having the multimeters reading voltage at the test points for the current on the output stage as I turned the supply voltage up. The leads were leaking or something even though they were supposed to be rated for that voltage. So when they were getting close to breakdown is when the noise and meters would start acting up. No multimeters attached except for balance and offset at the jack and it powered up perfectly. 60hz hum was entirely from the variac too. Listened to it for about fifteen minutes, left channel as regular carbon (driver + pair of 5k ballast resistors) and right as circlotron, and was impressed I could actually hear the difference. I was just hoping no noise problems at this point honestly. A couple minor notes on stuff that might be helpful for anyone else. In Soren's servo notes, the 5K resistor is the 500 ohm. Probably a 5000 code RN60 or something was the confusion I guess? I just bent the #2 opto leg up and away from the socket and soldered the 200ohm resistor to it directly so I wouldn't have to cut any traces. Everything else went together easy just as written. Almost everything has an open through hole slot from pulled parts or an easy place to hook up under a terminal. While the servo keeps the driver at about dead 0 balance and offset alone, through the output board it sits at about -5VDC offset and .2VDC imbalance. But it keeps it right there so I haven't fooled with it like Kevin recommended. Other than that, since last time I put new DIP sockets in the Output board, moved the sink mounted current resistors to a bracket on the Output board to shorten the wires and reduce the parasitic capacitance and make the output board easier to pull and service. Heat dissipation isn't as good as being directly on the sink, but still plenty I would think. Should hopefully finish all the stuff for the left channel tomorrow and see how smoothly things go when the output stages are turned on at line voltage from the internal relay instead of slow variac power up.

  4. it hurt for 30 minutes on the input end, and every 2 hrs since on the output end. The flavor was decent, if a little intense

  7. Jeremy Lin is awesome. Great player and great person. First American born Asian in the NBA IIRC. Great stuff! My brother and I talked about shooting hoops on our driveway like him, except ... he’s good. I liked that people called me Jeremy Lin, an actual NBA player! Instead of being called Bruce Lee or Charlie Chan all the time. Although Bruce Lee was pretty cool. But bum knee not good, especially for his style of play.

  10. thats not all, you can choose every stone you want and bring them a sample. then they decide if the stone don't effect the sound quality. they made one he-1 out of jade for a chinese customer. so noble sirs and ladies, it's now time for some creativity and a short call to your banker. of course they are open for your ideas (other knobs?), the conversation i had with my conciergie was nice, friendly and sometimes out of this world ;-). they made a real special services arount the he-1, was a nice experience.

  11. No love for Jeremy Lin? Considering last year, his career is pretty much guaranteed to be over at this point. Looks like Linsanity 2.0 was just not meant to be.

  14. They have arrived! The builder got the color exactly what I wanted and was able to match the trapezoidal shape of the speakers perfectly.

  17. dbel84 once again puts foot in mouth with this gem "I can also tell you that he will not be publishing any of the production designs for DIY. This is not selfish or mean spirited but rather more of a support issue as the boards are 4 layer and very specifically designed to perform the way they do - anyone trying to lay out a 2 layer board will run into some challenges. I had this conversation with him a long time ago as designs were retired ( Liquid Fire ) , and know that his positioned would be unchanged. Laying out boards was a gift that Alex had, I have yet to see anyone so skilled , it was part of the artist in him." I think birgir will agree that alex's layouts are among the absolute WORST that we have ever seen. Specifically for the Liquid Fire, LL mk1, LLmk2 and LG, they are all 2 layer boards with 1 oz copper, super thin lands that wander all over the place, and solder pads that are way to small. The left channel does not match the right channel on the Liquid Glass. The liquid carbon is just a terrible layout. As the stax mafia did in the past publishing every single singlepower design (except for one, never could get a active cable driver) I assume its our job to now publish both schematics and diy boards for every single cavalli product

  18. Our heroine, Camille, is still producing interesting music. This one puts me in mind of some of Kate Bush's more mature moments:

  19. Beginning my 48 hour fast until our two days of North American Cup fencing are over with. The hardest part is trying to appear to Lance that I don't care what happens at the tournament when the reality is my stomach is tied up in knots with anticipation.
