Thanks for all the birthday wishes! I had a great day building the Lego Roller Coaster set and had a fabulous dinner at a new favorite restaurant, MAD (for Madrid)! https://www.madhouston.com Everything was amazing!

Drilling and taping holes... amp boards now mounted to the sinks.

That one is getting close to Mooo!

I was surprised that he was shooting finish in such a small room. Looked like he had some kind of large-ish exhaust system set up though. Totally interesting! I remember a buddy telling me that he was spraying lacquer on hardwood trim in a bathroom and he tripped over the work light's power cord which was stupidly plugged into an extension in the room. The spark from the cord blew the room up and knocked him out. As he was being dragged out of the room, he could see the crown, door jams and base in flames. We used to set up some pretty big spray booths since we had to set up racks for lots of cab doors. We had a warehouse sized exhaust fan we'd point at folks we hated. Good times!

I was wrong about my unit! It didn't like being plugged in to a hub. Wanted to be directly into the USB port on the PC. Also, I had to start my power supply at like 2Vdc and slowly ramp up to 32Vdc. It came to life after that.

On the plus side (allegedly)* ... https://www.dailymail.co.uk/news/article-2119505/amp/Kazakhstans-prostitutes-cleanest-region-Shocking-blunder-Borats-National-Anthem-played-medal-ceremony.html * All that superior potassium, obvs.

I just finished designing this battery protector board. It has a built in balancer to try and keep the cells at the same voltage. I added a thermistor that gets fed up to the battery management on the amp board. This also has it's own thermistor in the middle of the board. I'll set this to about 50 C for both and do some testing once I get this built. The board is 10mm x 56mm.

thank you! i will integrate raspberry in my dac project

Really enjoyed the whole build. I use a lot of those same cabinet makers tricks. With waterfall Bubinga, anything less than such a high gloss would not do justice to that amazing grain. My only criticism has nothing to do with the turntable, but I'd prefer a bit more spread on those speakers.

The USB-C and battery management chips are crazy insane. It would not be possible to solder with an iron. They both have one or more exposed pads underneath the chips. Here's the USB-C PD controller... Those giant looking resistors on the left of the chip are 0402

I've done a lot of fine wood finishing but this is as extreme as I've ever seen (love to touch this finish!)

Curtis Mayfield - Curtis Live! Curtis is one cool MF'er. This is a great live set from 1971 at a small NYC club pre-Super Fly.

Meow.

This is a very early re-release, and has more in common with his early days as Buddy Holley's bass player, than the Country star he became.

That’s similar to what I do. But I have left and middle pins connected to one wire going to E on the meter while the third pin goes to C. When I measure j79/k216 I just put the transistor into the socket (be aware of orientation). For c3675 and a1486 I put their C and E pins into socket accordingly. When measuring breakdown voltages C and E are involved. If you want to measure Collector Emitter breakdown voltage than Collector to C and Emitter to E while Base is floating. In case you are measuring a Mosfet you should connect Drain to C and Source and Gate to E. Duoyi DY294 Operating Instructions.pdf

^^ love the vocal integration of that album (added to playlist) me

Done some soldering exercise today. This small board contains 100 x 0402 10K resistors. Hand soldered with a Weller station, XNT-H tip and 0.3 mm solder wire. A few of the resistors are not flat to the board but I think they are acceptable soldered. Looking at your board, Kerry, there seems to be some really nasty things. Any chance for part numbers? I have to convince myself that the best way is to pay for a prepopulated board…

As a person I've always liked Jude. I know I'm in the house that "disagreeing with Jude" built, but as far as headphone villains go he's pretty low on my list. That said, this interview is a little weak in the way of journalism.

A link to a thread on the other site popped up in my Google News feed, where a certain Mr J had a conversation with the "Sennheiser Brothers" and felt much better for it. Other comments deconstruct the statements etc. Ad blockers advised.

He doesn't say what the measurement bandwidth was. Which really makes it a very loose specification. The only hint is the very sharp mains harmonics in the noise plot, which are way sub-Hz in width. To get to -158dBV (-155.8dBu) from -107dBu on a 20kHz B/W you would need a measurement bandwidth of 0.25Hz, Shockingly badly specified.

The most significant issue with the THAT 1200 series of receivers is noise, -107dBu. It is dominated by the rather large values of noise-generating resistors inside (7k typical). With a good discrete design, or clever use of opamps you can get to -120dBu, which challenges measurement (<1uV in a 20kHz bandwidth).

There's also THAT - http://www.neurochrome.com/product/that-receiver/ The board's a bit pricy, but should be easy to implement.
