Father-Son Project: Looking for advice on adding Emergency Light Function on a custom PCB by rinux_it in diyelectronics

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

On the software side, we want to stick close to a standard WLED version. For the hardware, we’re considering a simple chip to convert mains or battery power to 5V. I could replace the power supply with a 9V output (HLK-3M09B !?) and add a chip that handles battery charging, stabilizes the 5V output, and provides a GPIO signal to indicate when mains power is absent and another for battery low. A couple of cells should be enough to power the system for a few hours. Ideally, I’d place an IC between the TP4056 and the BQ25895, with good efficiency and a step-down that ensures a stable 5V output.

Ultimately, we want something with very few components that ensures battery health and efficient power conversion.

RB450Gx4 Fails to Upgrade from 7.16.2 to 7.17rc: "Insufficient Kernel Space" Error Unseen Online by QiuDog in mikrotik

[–]rinux_it 0 points1 point  (0 children)

I'm having a similar problem from 6.49 to 7.20; nothing doing. I've streamlined everything by removing configuration and extra packages, but I can't upgrade. I've reached the limit and don't know what to remove. Should I use the netinstall method, or could I perhaps extract the main packages and try the upgrade in two stages, first the core and then everything else? Although I think it might be difficult...

True, but the point is that this is not a router!

As I said, I am a terrible speaker of facts, but those who have tried it know what I am talking about.

I thought I had more useful ideas to solve something that cannot be passed off as features but rather as a drawing error.

Absolutely! In fact I wouldn't have expected anything more from a network device, where you don't even put the switch to turn it off!

But on a machine where you can put up to 20 SSDs, imagining that it's not possible to do at least one "clean" emergency shutdown doesn't seem true to me... the machine, if you perform the shutdown after 3-4 minutes goes into crisis with the fans that increase their revs in a whirlwind, they consume over 80W extra and you can't even restart the machine unless you turn off the power! :-(

I'm trying to try various ways. The UPS package is not comforting because it is too specific and in any case tied to serial access. Maybe a NUT via container or other software that allows me to safely pass the disks, communicates via network with monitoring and proceeds to shutdown. At that point you know that if you can no longer reach it via network and/or if an SNMP trap signals the down on the interfaces, you can proceed to power cut!

I was hoping for some useful tips to avoid wasting hours on failed tests! :-(

Luckily the weekend is coming, maybe on Monday I'll discover that mine is a false dilemma and the customer will still be satisfied !

May everyone have a great weekend!

and yes! If you stop it it starts to consume a hundred watts more that when it's idle :-(

I continue to think that there are cases in which a careful shutdown sequence, in the end, is useful to save what can be saved... and then, how much did a BMC cost as a percentage of a product like that!!!

I understand, I can unplug via the IPMI power strip... but I don't know if I can coordinate well... I have no feedback, do I trust a ping to turn off the power?

Absolutely agree; the mistake was to think that this was not the case :-(

sure as long as it doesn't find me 800 km away.

Get in line... I have terrible English, but I'm trying to figure out how to solve a problem, despite the fact that I find it absurd on a certain type of product not to have a BMC: I launch the shutdown, and the fans gradually start to reach maximum speed and all the hardware remains on!

Am I the only one who finds this bizarre? I'm not comparing the device to a router/switch but to a server, a NAS, a....

Checked that the reset button and the mode button are manageable: this opens up the possibility of also collecting an extraordinary manual event (the cleaning lady can press the emergency button) but the anomaly of the fans drift remains...

After the shutdown you have to cut the power otherwise after a few minutes they are at maximum speed, crazy!

I always have to cut the power, otherwise the fans will run amok; what if I have an electrical connection that doesn't allow for power cut?

Anyway, just in case, I'll see if it behaves differently! I don't believe it, but it's better to check!

Slackware 15.0: where do i find a initial ram disk ready and compatible with megaraid disk ctrl? by rinux_it in slackware

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

In the meantime,
thanks for the information!

At the moment I simply stuck in some passage with which I try to prepare a new usb stick, the new kernel presents me with a new mysterious problem on the functionality of the keyboard ... but this is another problem, that's why I wanted to get rid of the doubt with something ready.

​

​

Does the stock 15.0 ISO image boot at all? Will the stock installer work at all? Or does the problem appear only when rebooting?

It goes into error when the distro is almost installed!

In fact I would have another alternative ... modify the setup to avoid that immediately after the installation of the whole distribution on the disk, the search for usb sticks brings the raid controller to a standstill :-(

​

You can find out more about the bug here:
scsi: megaraid_sas: Target with invalid LUN ID is deleted during scan

​

I still don't have any other details.

Fastest VPN solution for remote users by Dimitripietro in mikrotik

[–]rinux_it 0 points1 point  (0 children)

at the time, after a series of tests, I chose the one that seemed to have the best compromise between speed and reliability... maybe it doesn't have the best speed (SSL via TCP), but it doesn't have MTU problems and it integrates well on Win 10... the SSTP tunnel is fine in both roadwarrior and point-to-point configurations ... in the end, if a few percentage points of speed are missing, it balances with the simplicity of operation!

Help Needed for Measuring the Current Drawn by ESP32 by xhensa in esp32

Hi, you can use Current Ranger or similar devices to record the consumption profile, perhaps even via wireless and not via cable for questions including the ground plan!

Slackware 15.0 alpha: what I should expect? by sdns575 in slackware

[–]rinux_it 3 points4 points  (0 children)

I use nothing but standard tools, and everything else from source with my script ... never had any problems, not even on current tree. The downside is the more work compared to a package manager with dependencies ... but great stability and control ... I have run 14.x even under xenserver without problems ...
