  1. What The Hell Happened to Head-Case?!?!? TLDR version: The datacenter that the head-case server is located in sustained a power outage on April 4. When the backup generator kicked on it caught fire and that lead to the fire suppression system (a fucking water based one!) kicking on and causing water damage to equipment. The head-case server was in the 'more affected' area of the datacenter and as such was offline until early in the morning on April 24. For further details on the incident you can see here: https://webnx.com/outage-updates/ You may be wondering why during such a

  2. Some more good progress. The amp is up and running I've got two issues on the board, but the amp, power supplies and USB-C PD / battery management are all working great. The wires going to the pot are temporary. There'll be a board for the analog/DAC inputs. The PD chips are small with lots of pins on them. I'm surprised I could solder them Lots of 0402 chips on the right side of the board... Here's the amp running with the battery (I need to have the input board done before I can put the batteries in the chassis). This is with the amp run

  3. Milo and Otis, wow is all I can say. As for me, a gift for a disabled warrior to go with a wheelchair ramp for his house. Carving the handle was one thing but etching the trident was a nerve wracking endeavor. One shot with no do overs. Thanks Mark, you da man.

  7. In other news, I just got back the analog input board and assembled the amp. The sandwich is 6.2mm thick + bottom components for a total of about 9mm thick. Batteries are about 10mm on top of the input board. Back plate on and plugged into USB-C (charging LED on) Why we did this... Portable music Just analog from my phone at the moment. DAC is up next PS The Weight is 12oz or 340g

I got the full set of Bow Clamps last night for $40, a 7x10 Wilton Wood Vice for $60 and a Leigh D4 Pro dovetail, finger joint tool for $120, all mint.

  13. I have been continuing to play with turntable motors. I have two projects, one a controller with platter speed feedback for 3-phase AC motor and another controller for DC motors, which is an ultra-compact version of the one in swt61’s turntable to drive the Maxon motor. Here are some photos, just got things soldered up and have a whole lot of very tedious testing and software writing to do in addition to the SAMD microcontroller, that cutout is org castellated pads will also fit the new Raspberry Pi 2040 chip, which I am hoping to play with a bit. I hope they work!

  19. Building the world’s least efficient hardwood cutoff storage cabinet. Really needed the drawers above it so instead of doing the typical, proper, vertical cabinet, I went half-assed and threw all the sticks in a big drawer with sheets goods held behind the cabinet against the wall. Oh Yeah, the reason for the uneven overhang is I am going to mount the Wilton Woodworking vice on the one side and needed all the clearance. Oh Yeah Part Two, I also FINALLY got around to hanging the small French cleat panel I made way back. The craftsmanship in these holders in embarrassing.

  20. 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…

  23. Here's the final board I just sent out to get manufactured... I added some more optional parts that help stabilize the current sense circuitry. The board is now 10mm x 58.4mm x 1mm. Parts are ordered, so it's a race to see if Mouser can ship my order before the boards arrive.

  27. Woo, looks like the CPU board is working! Currently set at 20.29 Hz for 33.33rpm output. Got the front panel also working and now just need to solve the issue of the reflective IR Sensor (or go back to a magnet) - which I think might take a shroud to try and reduce stray light. The second display will then read out the actual platter speed as measured by the tach. Then I can adjust the speed in a feedback loop (PID). Still smells like a busted cap though

  28. Over in blighty, there has been a ridiculously successful re-introduction of the red kite. This 6 foot wingspan raptor was pretty much extinct here, but is now a familiar sight in our neck of the woods. There are now apparently nearly 5000 breeding pairs. We see them pretty much every day. They are social birds and will hunt and roost in groups. Because of food pressure (they eat mainly carrion, and odd large insect) they are now almost feral, and will apparently occasionally take a small mammal. Beware cats! I'm sure the red kite has been responsible for some small cat disappearance

  29. Thanks. I think I'll pick one up. I've had the amp playing from 9:00 this morning (did I mention it really sounds great ) and batteries were down to 9.8V at 3:20PM. They are not perfectly balanced so one battery is at 3.1V which is below the minimum 3.3V recommended. So looks like I'm getting a little over six hours with these batteries (3x2000mAH). I can look for larger batteries and also play with some optimizations. I've also been running additional 5V and 3.3V supplies for the DAC that consume extra power. They're not needed for just the analog input. The balancer should h

  38. Longish term modern DIY T2 reliability. I estimate its been used around 8+ hours (and more often than not 12 hours) a day almost every day since I built it. yesterday I took it apart for cleaning. I noticed all four 140K resistor strings connected to the voltage reference in the virtual batteries where somewhat discoloured.... hmmm... on further testing I found the D24 led on both channels did not light up at all not even dimly. :-(. but the amp seemed to work and sounded good. (on the left is a brand new resistor from the same pack as the 140Ks I removed from the virtual

Experienced a bit of normal today....met son Andrew and his girlfriend Amy at an outdoor-seating Bertucci's for lunch, and then visited the new (4,000+ sq ft) home of some family - niece on my wife's side, her husband and their slightly new baby. Was so wonderful to see everyone, and the new house is fucking amazing!

  41. For those that don't know - https://www.datacenterdynamics.com/en/news/generator-fire-brings-down-webnx-data-center-in-utah/ Short version - power outage at the data center, backup generator kicks in and catches fire, fire suppression systemin triggered, lots of damage ensues. HC's server was amongst the most damaged and thankfully, in the end, was able to be repaired allowing for the site to be restored. Thanks to Todd for sticking with us for all these years.

  42. I remember those little, lightweight, plastic headphones with the Yellow foam earpads that were so different than any other headphones out there in the 70's. You could actually listen for hours without your ears sweating. They were definitely innovators. End of an era, but change is a constant.
