conda-recipes/master efaabfe Sebastien Bourdeauducq: pyqtgraph: use m-labs fork
<cr1901_modern>
Ahhh so pyqtgraph was forked? Does this mean I should place the custom parts of the scan widget (essentially a GraphicsItem called "number line") in that tree?
<cr1901_modern>
ping sb0 (hopefully in < 7 minutes b/c need to do Winblows update)
<sb0>
cr1901_modern, pong
<sb0>
yes, I guess
<cr1901_modern>
I may be able to get PlotItem to do what I want as well by removing the Y axis. I have notes that I wrote on how pyqtgraph works; subclassing ROI (Reigon of Interest) and PlotItem should be enough to get the "drag" functionality without me having to implement my own widget without any help in PyQt.
<cr1901_modern>
PlotItems become each data point, and then I have "some way" (to be determined) to notify spin boxes of drag events and manually adding data points, and vice-versa
<cr1901_modern>
Aaand, time's up... :(

whitequark: Can you make a video of your new toy melting under use?
<whitequark>
huh?
<cr1901_modern>
"toy"==(poorly designed) buck converter, since you say it gets to be like 60C in casual use
<whitequark>
who said it's poorly designed?..
<whitequark>
its top efficiency is 91%, which is typical for its class. my laptop consumes about 65W max, which means in such case the converter will dissipate 6.5W
<whitequark>
I'm actually impressed with how cold it runs, expected it to be worse
<cr1901_modern>
that's what I got out of your tweets; the PCB was designed incorrectly, and I took your poll about "adding a fan or shipping it" as that "it got too hot in casual use." Guess I misread
<whitequark>
incorrectly?
<whitequark>
no, it's an aluminium substrate PCB that's actually way better than usual
<whitequark>
it's supposed to be used with a radiator at over 3A output, but I don't have much space for one
<cr1901_modern>
Attaching it to your laptop is a pretty cool idea; is it outputting the rated voltage for the laptop (not that +/-0.5 would kill it)?
<whitequark>
I only had the 18kOhm resistor for feedback which translated to about 20.1V unloaded; let me see how much does it output loaded
<whitequark>
19.77V, which is pretty much perfect
<whitequark>
the vendor's PSU is rated 19.5V
<cr1901_modern>
Wow... very nice! Glad you clarified/I was mistaken.
<cr1901_modern>
Building my own power supply is also on my bucket list; linear of course would be easiest, but I suppose I should try to make something compatible with this century.
<whitequark>
this one uses an xl4015e1 buck converter
<whitequark>
add diode, inductors, caps, two resistors, it's done
