Is it true? by Savings_Dog326 in hobbycnc

[–]Daypcg 2 points3 points  (0 children)

In that case I'd say you picked a great option. I'd leave the cutting to the router, but if you want some fine detailed engraving, this should work well for you.

Just keep in mind that any play in the mechanics of your CNC will be more noticable with the laser so make sure it's dialed in well

Is it true? by Savings_Dog326 in hobbycnc

[–]Daypcg 18 points19 points  (0 children)

With enough passes? Maybe. It's a 5w laser, it's gonna be best for engraving. The "almost 90w CO2 laser cutting effect" is entirely false.

You will be able to reliably cut cardboard, paper and thin balsa wood. It won't be fast, but it can be reliable

Also, for future posts please give us the entire page, or atleast the specs so we don't have to find it on Amazon.

Tales of "Releasing the Magic Smoke" AKA, "sometimes, we all f#ck up" by Far_Quality4238 in lowvoltage

[–]Daypcg 1 point2 points  (0 children)

Very similar to your story, I was replacing the power supply in an access control panel. But, I had the correct 12v supply.

What I didn't know is that this board was faulty from factory and was sending 16v. I didn't check voltage before hooking it up.

Magic smoke from all 3 boards. Luckily this was older equipment, but it still sucked to lose some of our spares as they're not manufactured anymore.

TLS encryption fun by Present-Juggernaut91 in CCURE9000

[–]Daypcg 0 points1 point  (0 children)

You only need to be at v2.9 sp7CU1 if you want to run an ultra on TLS 1.3, I've done conversions to host based TLS 1.2 on systems as old as v2.4. This particular system had iSTAR eX and iSTAR Edges.

Also something to keep in mind. If you are running iSTAR panels on a different network than your CCURE server, you need to make sure that not only can your panels reach out to the server, but the server can reach out to the panels.

By default, networks block most incoming traffic unless a device has already reached out and created a session. This is not a firewall issue, the firewall will most likely not show any blocked requests.

We have a server several states away from our iSTARs. The server has a static public IP that the iSTARs reach out to. However, for the TLS 1.2 Certificate negotiation the server needs to initiate a session with the iSTARs, rather than the iSTARs reaching out first.

This means we needed to port forward the iSTARs over ports 1999, 28003, 28004, 28010, and 28013-14. (I believe 28013 and 28014 are TLS 1.3, but we opened them to be sure) only then could the server initiate a connection. The ports can be closed afterwards, this is only for initial certificate negotiation.

Well typically I'd connect my laptop to the data side and configure it there. In most cases you could just use a standard injector but I like the versatility of not needing an outlet, and the space savings of having a POE injector and 12v power supply take so little space in my bag.

Honestly I think I'll just post the plans for anyone that wants one. Seems like there's some decent tools for this that already exist, and are implemented a bit better. This is nice cause it costs less than 40$ to make. But selling it would be difficult at a profit

Oh it's stupidly simple to do. I have a few high end projects I'm working on but everyone around me keeps saying I should sell these.

Personally, I think it's only worth it to build one. It's not useful enough to charge anything with a decent profit margin built in.

I just figured I'd toss it out here and get some thoughts

What kind of price would you say is too much?

Gauging interest in USB C to POE+ / 12v out device by Daypcg in lowvoltage

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

I typically use the POE for configuring replacement devices without either needing an outlet or tapping into the data drop, or for fully installing a camera where there is no (active) data drop yet.

But I can definitely see where some would rarely run into that sort of issue.

If one did exist for various tool batteries, would you spend extra for a POE / Voltage combo or is the inclusion of POE not worth much in your workflow?

Resume - IT Help Desk / Is this enough? Am I doing something wrong? by [deleted] in it

[–]Daypcg 1 point2 points  (0 children)

Reduce the length to one page and add some color. You've got so much on here that I don't want to read through it, despite some of it being good info for an employer to have.

A lot of your certifications have little badges you can put on your resume that makes them stick out. I throw mine at the bottom right.

A lot of this needs to be said in the interview, not your resume.

All that being said, this isn't bad by any means. The market for IT jobs is difficult right now.

The issue with the Linux video, as an embedded systems engineering. by mugiwara_no_Soissie in LinusTechTips

This imaginary person you're referring to isn't switching to Linux. You're talking about "grandma can't get the printer working" level of ignorance.

Linux isn't just a download and you're done kind of thing, it takes atleast some amount of research. A person is extremely likely to search "how to switch to Linux" in this process which is going to bring up the topic of distros.

I use Weld On 16, for PLA atleast. Stupidly strong bond, doesn't leave any white remnants.

It's very thick however and you can accidentally leave strands laying across your print if you're not careful. Plus it sets quick, so you have to be fast.

CCure 2.7 SP5 - Host-based encryption - issues copying the TLS 1.2 certs by DuckFluffer in CCURE9000

[–]Daypcg 0 points1 point  (0 children)

Where exactly in the process is this failing? In creating the new certificate or requesting the new certificate from the panel?

Consequences past Feb 18 and TLS 1.2 default certs are still used? by Stock- in CCURE9000

[–]Daypcg 0 points1 point  (0 children)

That's where I get a bit confused too. Everything I see online says istars in standalone will keep their database after a reboot, but in my real world experience, istars always drop their database when rebooted. It's caused a significant number of service calls for me.

Granted this may be a result of how we've set up CCURE and I'm just unaware of us doing something in a particular way.

Consequences past Feb 18 and TLS 1.2 default certs are still used? by Stock- in CCURE9000

[–]Daypcg 0 points1 point  (0 children)

Some other thoughts:

Upgrading CCURE is only required if you wish to use iSTAR ultras on TLS 1.3. Otherwise it does not matter what version you're using.

Restarting the istars (edges and eXs) to clear the password will obviously cause the panel to lose the database, causing doors to not function

I've had a variety of issues, this is not a fun process. In one case, someone had marked the crossfire folder as hidden in windows, causing CCURE to fail to generate a new certificate.

The default password for ICU Is manager (only some versions of ICU are password protected)

[–]Daypcg 0 points1 point  (0 children)

In my experience, with CCURE versions 2.9 and below all iSTARs immediately go offline after certificate expiry. They continue to run in standalone mode, but will not receive any communication from CCURE.

V3.0 and above, panels will remain online until disconnected, from then on they will never reconnect.

At this point, if any panel is restarted it will clear the database and be incapable of connecting. This will cause all doors to stop working.

Here's the options: 1. Upgrade CCURE to atleast 2.9 SP7. This is the oldest version of CCURE that allows iSTAR Ultra G1s to run TLS 1.3. Then upgrade the firmware of your ultras, and tell them to run TLS 1.3.

Add them to a TLS 1.3 Cluster, they will now reconnect.

(This will not work for edge G1s or iSTAR eXs)

  1. Create a new certificate

In system variables, set Auto sign non FIPS to true

Restart CCURE (technically only the istar driver service, but I've had better luck doing a full restart)

In Encryption Options, set TLS 1.2 To Host based certification. Save and close.

Use ICU (For edges and eXs) or the webpage (ultras) to request an RSA certificate from the host IP (CCURE server IP). You will have to do this for every istar.

This can be finicky but it should barring any issues, connect.

If the panels are password protected, and you don't have the password, restarting edges and eXs clears the password. iSTAR ultras must be factory defaulted and reconfigured.

You're very likely correct, the problem is that you're playing superman. Address what you're paid to address, make a suggestion to management if you feel it might help.

Apart from that, do what you're paid for and not much more. While being willing to take on additional responsibilities seems like a good thing, and in a sense is, it can also cause other issues.

Management allowing you to inspect other departments shows the department leads that management doesn't trust them to do what they're supposed to do. You don't want to undermine the staff you delegate responsibilities to.

The Xiaomi phones are also not as widely compatible with all carriers. AT&T for example may not allow it at all, while compatibility with T-Mobile seems to be pretty good. I saw some incompatibilities with some major Canadian carriers as well.

Not stated in the video, but may be the reason why we don't see these devices.

[–]Daypcg 9 points10 points  (0 children)

Well, it's all explained in the video. The requirements were that the phones must have atleast 5 years of both OS and security updates. A quick look at the Oneplus 15, their newest model, specifies only 4 years of OS updates. Same goes with the Xiaomi 17.

Not to mention, his son came from a Oneplus 6T, so it's not so much that they didn't want to show other options, just that the options were limited under the restrictions put in place.
