I just rotated a hot tub by 90 degrees, with the help of Tom.

This was not, err, easy.

But it means the heat pump conversion this week will be much easier.

The hot tub came with the house, and I had no idea at the start how expensive they are. A heat pump will help a lot, I hope.

The house also came with a fence approx 1m inside the border wall, which was silly, but was cheaper than making up the wall to a good standard, which we are now doing.

Houses are costly some times!

WilliamLeech,

@revk What heat pump are you getting for the hot tub? Another Daikin?

New Octopus tariffs loaded, and hot tub refilled, and sunny, and then you get this sort of weird!!!

That is quite a lot of power moving around in odd ways, all at once!

WilliamLeech,

@revk My perception is that I have seen a lot more oddities like this in my Tesla app recently (last month or so).

I know this may look bad...

But this is how it has ended up.

https://www.revk.uk/2024/03/separating-waste.html

Should be an interesting couple of weeks to get in to the swing of things.

WilliamLeech,

@revk I have gone back & forth on the issue of kerbside separation of waste over the last decade:

On the one hand, separating waste before it becomes mixed seems logical and straightforward.

BUT. What happens when a human makes a mistake? Discard a large amount of recycling because it has been contaminated? Expensively sort it "just in case" ?

Then there are the deposit return schemes for recyclables - does the existence of these schemes mean that kerbside separation of waste isn't working?

Starting now, the sponsor setup and situation for #curl donations is documented: https://github.com/curl/curl/pull/13119

WilliamLeech,

@bagder I think "We plea to use donated funds" might be meant to read "We plan" line 12, SPONSORS.md
(I don't know how to use Github to suggest this in the correct way, sorry)

@revk@toot.me.uk avatar

Top tip.

Do not have any other TAGGED VLANs leaking out on your #Starlink bypass mode link.

It appears that they answer all ARPs they see, on any VLAN tags, with an untagged reply for the Starklink gateway MAC. Also, if you have a lot of them, the Starlink will stop working (lots of on/off making around 80% packet loss average).

I have been tracing this around my network for the last few hours.

WilliamLeech,

@revk At the risk of asking a dumb question, How many VLANs does it take before it starts to be noticeable? I don't think any of mine leak, but I suspect I have fewer VLANs than you.

WilliamLeech,

@revk Thank you! I wondered if it would be 1, then I reread where you had said if you have a lot of them and thought: You run an ISP, I know basically nothing in comparison and it's better that I look dumb by asking than by assuming.

🆕 blog! “Giving the finger to MFA - a review of the Z1 Encrypter Ring from Cybernetic”
★★★★☆

I have mixed feelings about Multi-Factor Authentication. I get why it is necessary to rely on something which isn't a password but - let's be honest here - it is a pain juggling between SMS, TOTP apps, proprietary apps, and mag…

WilliamLeech,

@Edent How does it work where the authentication is NFC + PIN? I imagine it being awkward to hold a finger in place on the NFC reader while typing with the other hand?

WilliamLeech,

@Edent Does it not support it? I thought it was part of the Webauthn spec.

On the one hand it seems a shame if such an expensive device can't do it it, on the other I'm not sure it would work well with a ring format.

Edent, to linux
@Edent@mastodon.social avatar

Woo! New gadget acquired!

If you have any tips for reading, writing, or using #NFC with #Linux - please let me know 😄

WilliamLeech,

@Edent Yubico security key WebauthN credentials stored via USB are available for use via NFC (and vice versa) rather than there being two separate stores, which I think is a handy to know for debugging

Edent, to linux
@Edent@mastodon.social avatar

I'm looking for an #NFC reader to connect to my #Linux laptop which can be used with #WebAuthn / #PassKeys.

Anyone have a personal recommendation?

Boosts appreciated 😀

(Not looking for search results or opinions on alternative tech, thanks.)

WilliamLeech,

@Edent @ben The Omnikey 5022 works with Yubico NFC on Windows (including the PIN). I have a vague memory of testing it once on Ubuntu a few years ago. Might be able to test it later if that helps?

WilliamLeech,

@Edent Couldn't get it to work passing it through into a VM this time. Don't have any Linux running on hardware that I can use for testing at the moment.

OK if I must, some customers in the US!

@steve @revk Could feel better by adding Rankine?

This is driving me mad. My new 7.5" e-paper boards work nicely, and mine on my front door is running on 12V and working perfectly.

But one for my son is not, it is using a USB lead, 5V.

It works on a short USB and not a long one. I have literally cut tracks to get down to just the regulator and ESP32 and USB socket, and still no joy. But if I connect a serial header with the same regulator on to the board using the same long USB cable that works.

Almost like I have a batch of iffy regulators?

WilliamLeech,

@revk These power issued has made me wonder; have you thought about putting POE and wired networking on this board?

revk, (edited ) to esp32
@revk@toot.me.uk avatar

Yay! Finally, working door bell with status message for couriers. #ESP32 #PCB #Epaper

More detail on my blog: https://www.revk.uk/2023/11/no-no-bell-prize.html

WilliamLeech,

@revk I like this very much, even though the cynical part of me is wondering how long it will be before couriers start telling you that the "touchscreen" is "broken" when they press the camera "button" on the "touchscreen" and nothing happens

revk, to random
@revk@toot.me.uk avatar

So, I think I have the new door bell sign finished.

WilliamLeech,

@revk Play the couriers who do seasonal tracking icons at their own game!

@revk@toot.me.uk avatar

Well, it fits well in a resin mould. I really should do some s/w before setting it in stone (or resin).

WilliamLeech,

@revk Door bell?

WilliamLeech,

@revk I will! I'm rather liking the idea of an e ink sign, I have sometimes thought that there must be a better way when I sellotape a sign printed on A4 paper for a courier!

I made the very understandable but naive assumption that a USB-C "plug" (pin out as per datasheet in this image) would be wired the same as a socket. Specifically that CC1/CC2 need 5k1 to GND so as to get power by default.

But no, it seems a plug has CC and VCONN, and needs a 5K1 from CC to GND, but NC on VCONN. The datasheet could have said CC and VCONN, but no!

So, it works in a USB-A to C adaptor, as power is fixed in USB-A, but not in any actual USB-C socket. FFS

#PCB #FFS

WilliamLeech,

@revk @threedaymonk @revk You might find the USB PD spec helps you more than the USB-C spec https://www.usb.org/document-library/usb-power-delivery.

Also, it's very much an edge case that probably won't ever apply to you; but, USB power delivery isn't restricted to Cs only, you can run into it on an A or B too, it's just rare that it gets implemented.

Starting soon, you might need Windows XP or later to run #curl on Windows... Yes, the XP that was introduced in 2001.

https://github.com/curl/curl/pull/12225

WilliamLeech,

@bagder Tangential question that that thread has made me wonder: How do you decide what to put in the user surveys? I recently worked for someone creating a survey and the attention to detail in the design to try and get the most useful data there was mind boggling. Given how important #curl is, it makes me wonder how you do it?

WilliamLeech,

@bagder That's true, I saw analysis of a survey being done too. It was eye opening (for me anyway).

WilliamLeech,

@bagder Thank you, that'll be some interesting reading for me

revk, (edited ) to stargate
@revk@toot.me.uk avatar

This is the Mk3 #Stargate #PCB design.

  1. Additional LED in 3rd chevron ring to allow chevron "lock" effect better.
  2. New kawoosh ring that shows inside the 100mm gate opening (idea it to play with mirrors).
  3. Additional snap off tooling holes for jlcpcb.
  4. Additional snap off fiducials for jlcpcb.

Now 498 WS2812B RGB 1x1mm LEDs!

(yes, the snap off bits make it looks like a space gate, I know 🙂)

Seriously, the doctor was quite insistent that I should "take it easy" for a few weeks 🙂

WilliamLeech,

@revk I used PCB train and was happy with their work, but that was quite a few years ago now (I don't really do many boards).

Remember my story back in April when people removed #curl from their Windows installs? https://daniel.haxx.se/blog/2023/04/24/deleting-system32curl-exe/

It is now happening again as Nessus identifies curl as vulnerable to this #CVE. Which admittedly is true.

WilliamLeech,

@bagder I thought Microsoft had improved shipping the current version of curl.exe in Windows to avoid this sort of thing - have they dropped behind again, or did I imagine it?

revk, to random
@revk@toot.me.uk avatar

Surprisingly comfortable…

WilliamLeech,

@revk How did you get one? I haven't been able to get spare filters for mine since Amazon US stopped shipping them to the UK.

WilliamLeech,

@revk Thank you!
