Just did 5.5 miles in the woods, 500 ft of climbing. Heart rate basically never dropped below 150. Felt like I was going to die most of the ride, but I did it, so next time should be easier. Made a friend

It was actually very easy to rebuild the large T2 with the DC/DC converters. Used same daughter board layout as for as for my modified T2, only had to move one hole 50th. I also have plenty of space since I only use one and not three output transistors and I found some nice spots for the daughter boards. One channel has the DC/DC converters and the other the newly made 01N100D/LT1021 boards. Both channels seem to work OK. Below: Daughter boards with LT1021 and 01N100D on heat sink. Boards with DC/DC converters and LT3045. Now it's late, done for today.

Just ordered the new 10" ipad pro, looks sweet! I have the 12" ipad pro and always want it to be a little smaller. Happy they finally have the new iMacs out. I'll be ordered one soon.

My old Macbook Air is pathetic and will be scrapped soon. I am considering the Macbook Pro with touch bar versus an iPad Pro with keyboard/pencil because I do not want or need both. Would Shelly or Adam or others who have both please speak up with which one they would pick if they only wanted one?

Probably an easier conversation to have over the phone. PM me if you want my digits and we can chat.

Night night Bron Bron.

For fans of the rotary engine... https://www.hemmings.com/blog/2017/05/31/four-cycles-three-chambers-60-and-50-years-dual-anniversaries-for-the-wankel-rotary-engine/?refer=news HS The post above I thought was posted days ago...LOL. Oh well. This one was intended for today....with some luck. Made me chuckle. HS

Half an hour of video nerdity. Gives me vivid flashbacks of working in a college media center, almost 20 years ago.

New Ultegra R8000

Hmmm I don't think I removed the loop out on any of ones I've done. Pop the hood and I'd know... In other news, as the SR-Omega owners know all to well...there are no more replacement earpads and the old ones are pretty much awful. Any set with the stock ones will be mimicking a block of wood by now and the replacements Stax used to sell were pretty fucked as they were just wrong. First of all they were black and then the dimensions were also wrong. They are all gone now as well so what to do... Well take a crusty set of earpads and re-engineer some new ones with the company that is making the earpads for my headphone project. Now they are real leather with memory foam. They are also thicker as they are much softer and the opening was made smaller to control the bass issues if the SR-Omega. Now this is the just the first prototype but what an utter fucking pain in the ass to install. I've sourced the pins Stax used and I'll order some new mounting rings for the next batch but yeah, not easy to install. Something I'm not sure can be changed but we'll see. Here they are mounted to the headphones: Yup, the "old" earpads are new old stock but mine won't last forever. Now how does it sound...bloody brilliant and they are so much more comfortable. Some more listening to be done on my part but some of my issues with the SR-Omega have been greatly diminished.

Harmonic just means integer multiples of the fundamental frequency, whether they are odd or even. If you really want to get into musical harmony, the perfect fifth is not an even multiple of the fundamental with an interval ratio of 3:2 and neither is the major third, which is an interval ratio of 5:4. Even order harmonics represent octaves, which strengthen the fundamental which may or may not even be present, giving a larger than life ringing tone. A combination or Tartini tone is most commonly produced using a fundamental and its fifth, in which a common subharmonic is heard psychoacoustically. Overtones are any frequencies above the fundamental frequency. tl;dr solid state haters need to seek haven somewhere else.

Like Mike, I could never replace apps like Pro Tools or do actual work on my iPad so it's a "need" thing for me. I suggest you look at the apps on the Air and see if there are any that you'd really miss. But, if there aren't any (and don't have a reasonable ios version) you'd probably be happier with the iPad Pro. The track pad seems super clunky to me vs my magic mouse or touch os.

Well, since you are local if you want you can borrow my prior gen iPad Pro that I have listed for sale here for a day or two and see if it works for you?

So a gain stage is some how worse than a buffer stage and a step up transformer? Sure... this is the Craig Uthus line of thought. Let's paint all the way into the corner and then pretend it doesn't sound like shit.

Hats off to the Cavs. LBJ and Kyrie left everything out there on the floor and just didn't have the gas in he tank to get them over the finish line. KD!!!!!!!!!! Legacy defining shot for him

Just a virtually unknown little thing they called "The Walkman". Oh, and something called a CD player.

The Sony MDR-R10/CD3000, Qualia 010/SAx0000, & Z1R models are from completely distinct eras of Sony. They each represent such different (& pretty much opposite) approaches to a certain ideal that they might as well have come from different companies. Purk, if you'd like to hear an interesting headphone that is very reminiscent of the venerable R10, check out the Final Audio Design Sonorous VIII & X models. I heard them at CanJam NYC this year, & was left with more of an impression than from the Z1R.

Open up the earcup and u will see how crappy the wires are. I can't stand a stock SA5000 either, but my recabled pair has considerably less bright with a better bass to boot. Extracting details has never been the sa5000 problems. The SA5000 was around $690 new a few years back while the the Z1R doesnt sound quite as good as my recabled pair for three times the price hence the reason why I think less of the Z1R.

Bonovox and the boys are in fine form in the Joshua Tree Tour NYC concert on disc 2.

Today I’ve equipped my modified T2 with the 01N100D/LT1021 current source Kerry has simulated, see previous posts. From beginning it had a straight 10M90S set to 10 mA. When JimL came with the cascaded version I removed the two resistors at 10M90S and added a small board with the DN2540 and corresponding resistors(red circle below). Today I made new daughter boards containing LT1021, 1k resistor and 47pF cheremic capacitor (green circle). Have listen to this for an hour. It works and I’m satisfied. Thanks Kerry for coming up with this. Below solar cell. Only for experimental purpose.

Quicker or Faster? δv/δt or Vmax? And yet the quickest car was the least fun. I'm glad they took your advice and decided not to make such a worthless comparison /s

Bought the lg 65 oled, will be here next week

Interesting -- I was a fan of the Aquos from the same time period, didn't realize the more recent ones were crap. That's too bad.

A great anecdote in the paper about Douglas Bader, the double-amputee English WWII fighter ace.

Roger Waters -- Is This The Life We Really Want? Oh fuck me yes. Where have you been for 25 years dude?

I got the HV sections and bias up and they work perfectly Here's the board... I've already tested the GRLV boards and they work. I just have to build another set for this supply. The thermals above the IXCY10M90S regulators don't go above 99 deg. F. Very happy with the board so far.
