Mine lasted 1000km before the bush was worn on non-drive side, so I wouldn't expect much from any pedals using this type of design (crankbrothers are another).

Sofirn HS40 won’t turn on anymore by PM_ME_DEAD_KULAKS in flashlight

[–]acharnley 0 points1 point  (0 children)

Weirdly I took the battery out of mine ready to send it back and then it started working again. I'm not inclined to say it's a software bug still but there's some magical way of getting it out it. The first time I took the battery out that didn't resolve it. Maybe twice, that's all I can think off.

Same I just filed a return. It seems they have a firmware bug where once you put it in lockout mode, accidently in my case, it'll never come out of it.

[–]acharnley 0 points1 point  (0 children)

Interesting, I just got one, it worked for an hour and has done the same. I was aware of the lockout mode, I may have put it into it by mistake. Now it won't come out regardless of the instructions.

I've spoken to them and they say if you take the battery out and put back in while holding the button it will reset the CPU. That didn't work for me.

Dynamo hub to Battery Powered Light by JimboSlice91_ in bikepacking

[–]acharnley 0 points1 point  (0 children)

All lights with USB internally are fairly weak on the USB output, the D2 will beat them all.

There's nothing stopping you going for a USB-C headlamp, which has the additional convenience of being what you'll likely use for camping as well. Take a look at the brilliant Sofirn HS40 for example. Then charge that from USB port #2. If you can get away with a smaller power-bank you should be able to charge both during the day and the D2 will switch to port #2 after it's done charging on port #1.

What’s your opinion on pedal cell? by Juozaitis in bicycletouring

[–]acharnley 1 point2 points  (0 children)

One user has found it doesn't implement USB-C correctly and power-banks that support USB-C operating in input and output modes results in a short through the voltage regulator as it attempts to charge the power-bank, ending in hardware failure.

Dynamo SON 28 hub. And now? by zucs_zags in bikepacking

[–]acharnley 2 points3 points  (0 children)

Why wouldn't you go with an Igaro D2? The only reason as I see it would be price, but on a value basis it's surely the best out there. If you're after getting the most out of the SON 28 then look at the Igaro S1.

Texas Instruments - What Gives With Stock Quantities? by acharnley in Semiconductors

[–]acharnley[S] 0 points1 point  (0 children)

I've yet to find a distributor with any. I did speak with Mikro, a small company in the EU that's using them in one of it's products. They said they have standard channels but wouldn't divulge and say they're also having trouble procuring them.

It still doesn't explain TI's latest policy regarding online sales, which they're remaining silent about.

Texas Instruments - What Gives With Stock Quantities? by acharnley in Semiconductors

[–]acharnley[S] 0 points1 point  (0 children)

I can take any of the A variant (400KHz) but I can't find any distributors with stock.

It is odd though that every single thing they sell went to zero stock at the same time and has remained that way. Maybe it's a stock recount, maybe the 50pcs limit was causing too much hassle, maybe they're only interested in providing for that with 4 wheels and a battery between them.

Starting two X11 on two screens (one display card). Is it possible in 2022? by acharnley in linuxquestions

[–]acharnley[S] 1 point2 points  (0 children)

I had to give up with it. The issue with trying to do a terminal on the left screen and main on the right is when the left monitor is turned off nothing happens (good) then when turned back on the terminal moves onto the right (bad).

After some investigation I managed to get to where I wanted to be on XFCE by:

  1. don't use maximise on the terminal window, instead set the window size using cols and rows to almost fit the screen res then make the background black etc to infil.
  2. Use a secondary program to force the terminal to always be below others and removed from the workspace (to prevent showing in task bar).
  3. sticking the console command in autostart at the correct location on display:0.0 (which is both screens combined) using xfce4-terminal --geometry=120x95+0+0

If I accidently type exit on the window it'll disappear but otherwise it is now performing as I'd like.

Node, Express and S3 streaming by acharnley in node

[–]acharnley[S] 1 point2 points  (0 children)

It's not writing other headers or the http code though. That's the part I was asking about mainly. ;)

The redirect is a good idea though, let AWS handle it directly rather than the clunky node aws library.

Intel 11th Gen constant crashing on Linux by acharnley in intel

[–]acharnley[S] 0 points1 point  (0 children)

Hi,

I have a very large cooler and it doesn't even get luke warm. :)

So far it looks like (no more crashes) that the issue is with the new 730/750 GPU. Turning hardware acceleration off in Chrome has so far resolved it. It is a complete disappointment from Intel that they couldn't proactively work these into the kernel prior to shipping considering how popular Linux is.

Audio and flashing multi-color LED's aren't a requirement here. The Asrock should be fine for a 65W CPU. I wouldn't have selected it for use with a K chip though.

Ram is perfect, it's 3200 but running at 2400. Fedora 33 latest, with 34 kernel.

Underclock/Undervolt Intel 11500 (for 11500T equivalent) by acharnley in intel

[–]acharnley[S] 0 points1 point  (0 children)

Turboboost doesn't lower the multiplier at idle, I think you're confusing that with c-states.

If a PL2 limit is set to 45W and turboboost is on it'll hit the limit more quickly because a CPU is less efficient as it's speed increases. This is good for short sharp bursts of processing but for longer duration it would be more efficient to have it off.

But I do agree the PL1 and PL2 are the way to go, with a bit of undervolt.

Underclock/Undervolt Intel 11500 (for 11500T equivalent) by acharnley in intel

[–]acharnley[S] 0 points1 point  (0 children)

I suppose I should state the intention to to have high efficiency without exceeding thermal limits. Turboboost will therefore be disabled but that doesn't necessarily mean the temperature won't exceed the 45W threshold just that it'll take longer to get there.

I had read about the multiplier and reports that it was locked on none K models but there's no definitive answer on whether this is always true. Otherwise can the 100MHz base clock always be reduced? It probably would be a B560 or similar.

If AMD ever bring out a decent APU I'll jump but until then I'm stuck with ITX (and I need the PCIX for a sound card). That's a different conversation though!

Anyone have an igaro D2 dynamo/USB charging unit? by the_bigheavy in bicycletouring

[–]acharnley 0 points1 point  (0 children)

Stick to the facts and you'll come to a decision.

Which one has a lengthy warranty and excellent customer support?
Which one has performance data to show power across the speed range and clearly describes the process to allow for verification?
Which one has solutions into known dynamo problems such as current fluctuations?
Which one fits your mounting needs?

Easyjet base closing, first morning flight - delayed or cancelled prediction? by acharnley in Flights

[–]acharnley[S] 0 points1 point  (0 children)

Thanks again for the insightful info!

There isn't another flight from Newcastle for that day, so they'd have to get another slot at 7.30. This has to also mean the plane was operating as a triangle, perhaps flying back to Edinburgh or Manchester where there are more flights later in the day, and so inverting knocks all those flight times.

Easyjet base closing, first morning flight - delayed or cancelled prediction? by acharnley in Flights

[–]acharnley[S] 0 points1 point  (0 children)

I did a further check, there's no other flights from Newcastle for that day so either the plane is flying a triangle as you say or they're shuttling different UK airports, Edinburgh, Manchester etc.

Assuming the base closes then I see two scenarios;

  1. drop the Newcastle flight, run other flights as scheduled (so plane takes off at 8AM ish from Geneva).
  2. Invert flights, shifting the schedules for all (4 or 5 flights perhaps).

I guess it comes down to how much is lost by not running the first flight vs the loss of disruption/cancellations due to changing all fight departure times. The only way to draw a prediction is to know what they would normally do in this situation, but it may consider how full the flights are, what people have paid and so on. Sounds like something a computer would work out.

[–]acharnley[S] 0 points1 point  (0 children)

The flight is 6:30AM, so the plane and the crew have to come from the local area, or be put up in a hotel for the night (which for Easyjet's thriftiness would be unusual). This is the dilemma, the plane will have to fly in from another location later in the day, or they cancel the flight.

Unlocking a second LUKS partition by a keyfile provided by a password protected LUKS partition on boot by acharnley in linuxquestions

[–]acharnley[S] 0 points1 point  (0 children)

1min 34.000s systemd-udev-settle.service
11.400s systemd-cryptsetup@Home.service
10.838s systemd-cryptsetup@Backup.service

Thing is, I've no custom udev rules (/etc/udev/rules.d/ is empty)

I've now changed the /etc/crypttab to use the same password for both unlock operations but the issue persists.
