WaterWaiver
@WaterWaiver@aussie.zone
I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.
Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.

I don’t understand. Blorp looks like another backend you host as a website. But you call it a “client”. What exactly does it do and not do compared to compare to lemmy and piefed?
- Comment on It turns out there is a Lemmy alternative with categories - anyone got stories about it? 1 week ago:
Huh, it looks like the groups (of communities) are instance-specific. piefed.social has lots, piefed.au doesn’t. Then there are “feeds” which… look like the same thing as groups? Of which piefed.au has Australian-specific ones (including a lot of auzzie.zone communities). I’ll have to find out if any of these are portable across instances or not, or if I’m stuck using multiple sites to access the fediverse >:|

Ty Lodion. May I ask if it was malicious generic traffic or malicious lemmy-api-targeted traffic?

- Comment on Pretty part of the week: Lian Xin XDMD camera autofocus coils 1 month ago:
The ringing comp is interesting: it’s completely synthetic (sensorless). The chip models what it thinks the ringing should be based off some physical parameters (that can be configured over I2C), then drives the coil in a way that it hopes would counteract the ringing, but never actually knows if it has succeeded.
- Comment on Pretty part of the week: Lian Xin XDMD camera autofocus coils 1 month ago:
Similar to how you can do current sensing in motors
I do not think there are not enough variables here to make this work. Reading coil current won’t give you any information you don’t already know if you’re already controlling coil current. You need to be reading at least one more variable that is somehow related to coil position.
Turning off the coil drive and shorting the coil temporarily to measure current is unlikely to give you anything but the same current you were driving it with (minus some losses). Ie still not an extra variable.
you can send and receive with the same coil in a metal detector.
This introduces new variables! Reflected signal magnitudes (and distortions & phase delays) that depend on distance to a nearby metal object that you intentionally install near the coil (eg the metal casing).
Not sure how easy or reliable this would be to do in practice. I have my doubts but I could be wrong :)

Woah. I thought it was 3mm, not 3cm. This this is huge.

- Comment on ‘Wake-up call’ for Australian universities as 70% suffer a fall in latest global ranking 2 months ago:
FWIW there are dozens of university ranking systems and every university says “look how well we rank in X!”. It’s been 10 years since I looked, but I think I recall some of them being funded by unis too.
Nonetheless I agree they’re doing stupid stuff that’s not in the interests of students, staff, the country, humanity and education in general. Alas it takes them many years to feel the effects.

Every news website is covering it. I think I’ve spotted most of 10 articles around the place.
The law of well-marketed unreleased goods dictates that this vehicle is not going to meet any of the promises mentioned in the articles.

There are some youtube videos of people machining them (sadly no phenolic smell is communicated though). Looks like you treat it like any other solid material: hobb or mill the teeth.

If you end up buying some flux then I’d recommend you also buy and try a block of violinist rosin:
www.ebay.com.au/itm/315948528490
You break it up and then dab chunks onto your joint whilst soldering. Some will melt off and then burn. From there it acts just like any flux: reduces the metal oxides, makes the solder suddenly flow (behave) a lot better and provides some level of temporary oxygen shielding with its off-gassing products.
Pros:
- Cheap
- Doesn’t smell awful
- Long working time (easy to use)
- Very simple ingredient (distilled pine tree sap) made by many manufacturers, so it will never go out of stock.
- Residues are non-conductive and can be safely left on your boards
- Residues are reasonably easy to clean (isopropyl & most board cleaners work; ethanol also works but tends to leave ugly white streaks)
Cons:
- Smoke is still harmful (smoke = incomplete combustion compounds)
- Residue is dark, unlike the transparent residue of many no-clean fluxes, so it can hamper inspectability for mass manufacture.
- Best handled with tweezers, otherwise your fingers end up feeling sticky (pine resin compounds are slightly sticky)
- Not Modern or youtube popular, so people will tell that it’s therefore bad or worse than other products.
I use it often, it’s my favourite for both big joints and fixing smd work. Grab some and try it :) The worst you will be out of pocket is a few dollars.
- Comment on Questions about the insides of this optocoupler (TLP250) 7 months ago:
Triangle is an amplifier and rectangle is a black box (“don’t worry what’s in here, we promise it’s not gremlins”).
I suspect that the box might be a biasing array for driving the two output transistors, but then I would also expect two wires to come out of it (one for each transistor) rather than a single combined wire.
Broadcom’s datasheet for their version of the part seems to be more akin to what I’m thinking:
Could be either. You’d have to decap the chip to find out, the datasheet writers thought these details were not important.
- Comment on Pretty part of the week: Ruishen RSCM11548 3-winding common-mode choke 7 months ago:
So many CMCs seem to be marketed based of visual appearance and hope. I guess maybe people already have a design that works, so they go for things that look like clones visually? Otherwise I don’t get how anyone would choose their product when there are alternatives with actual specs.
Another gripe: When the only datasheet available is a combined one with tables and graphs listing the specs of dozens of part variants. But yours isn’t on there. So you find two similar models in the list and mentally interpolate between the graphs whilst worrying whether or not this is a long-term supply item or some spares that a retailer is selling off from a custom order run.

I just realised how hard it would be to manufacture this thing.
Imagine having to bend those copper wires into that shape around an already-existing toroid ring. Or maybe they glue together a few pieces of ring?

It’s 50 bucks though. Too expensive of a date for me.
