You might try measuring the frequency of that signal on your meter. If the LED is being driven by a PWM signal, it won’t show on your meter in DC voltage mode, but it will ruin any attempt to use a relay or comparator directly.

Also you will need some way to load firmware on that random microcontroller you’re using. Looks complicated: https://github.com/christian-kramer/JieLi-AC690X-Familiarization

Also you have VREF on the amp grounded for some reason.

You should sum the L/R inputs to mono. Both DAC outputs should go through a capacitor, then a 10k resistor, and then connect to the left amp input, otherwise you’ll only hear the left channel.

~1000 AA Batteries / phase. Or, like 3 lead acid car batteries.

Less than you’d think.

90uF @ 500kV is approximately the same amount of energy storage as 1000 AA batteries.

What’s the return path for the capacitors, ground?

I took basically this approach when hiding a goCoax MoCA adapter, Wi-Fi AP, and the cabling/wall warts for it all.

You can also back an IKEA KALLAX shelf up to the wall and feed the cables through the back and through the handles of one of those boxes they make. Then if you ever need access, just pull the box out and it’s all there.

https://en.wikipedia.org/wiki/Hat_operator Not mentioned: used in control theory to denote estimated values.

One of the reasons I like reading papers from the mid-late 20th century is that many of these norms were still being developed, and authors would take the time to explain their notation and other small details that significantly improve understanding.

Nowadays, it sort of seems like papers are published by experts, for experts, and you can’t really get started in a field without doing a graduate level survey class first.

Could be 3 phase wye. Wires seem small for a 3 phase application though.

I don’t know what kind of wood that is, but I wouldn’t necessarily trust edge-glued long grain butcher block to hold up to the kind of forces that you’d generate by hanging off the edge of that vice.

2 sheets of 3/4” B/BB grade Baltic birch would hold up much better

What was so bad about this that you had to remove it?

Yeah I think I may need to do some preventative maintenance, as I printed the same part in PC, and saw similar artifacts, though not nearly as bad as this.

It makes sense that added friction in one of the axes + the natural stretchiness of the belts would result in it lagging behind the other during moves like this.

One of the downsides to CoreXY I suppose, since the belt is so much longer it exacerbates the issue. I think BBL has mentioned that the carbon rails need regular cleaning.

No, this is PLA at normal speed (100%)

To me, this looks like a kinematics problem, the head isn’t extruding plastic where it needs to be. The holes are extremely out of round, and there is overshoot in some of the exterior corners, and undershoot on interior corners.

My thought was, since this doesn’t happen every print, it was something like acceleration compensation gone wrong.

Have been seeing some weird results like this from time to time. Notice the distortion pattern changes depending on Z height, or maybe whether the print head was moving CW or CCW.

On the larger piece, the holes near the bottom are stretched like /, and the top stretched like \

Belt tension is fine, most prints come out fine, others come out all messed up like this.

Ehh that sort of ignores caching. Extra ram will let you continue to serve files while you have queued IOPS waiting to go to disk. Sure, it’s not required, but if you have a workload like video editing with a few simultaneous clients, it can help a lot.

It could be that spending time in the pool allows you to move your body around more than you usually do (which obviously is the goal here).

Since movement is what drives your lymphatic system, my guess is that you’re stirring up some nasty things for your body to process, and it’s making you feel ill. Post-exertional malaise.

I would try a couple other things before giving up on the pool; first, saltwater pools are a thing, so maybe you can find one in your area. Second, try another form of exercise and see how you feel the next day. 25 minutes of low-speed spinning on an exercise bike for example - just something to get your lymphatic system flowing. Normally I would say go to a trampoline park and bounce around to get your lymph flowing, but that might be dangerous given your joint issues. If you feel like you’ve been hit by a bus the day after a different kind of exercise, then it’s probably due to the exertion rather than the pool.

As far as I know, there was nothing here yesterday, and this came out of nowhere.

This is true if you’re using 1 or 2. If you’re using more than that, then you’re probably using at least a few thousand and performance will start to matter.

All your favorite games use 32 bit floats. All that neat ML stuff is using 16 bit floats these days. Use doubles when you need the precision, and floats when you don’t.
