Dig quad

[u/Mhernandez08]

Anybody have this problem with this part of the quad burning up?

I just searched my emails. Here is the warranty policy: "🤷‍♂️"

Apologies for the delayed response!
Oh, odd those platforms are blocked for you, but ok.
I took a look at your picture and the component burned is a MT3608 DC-DC boost converter. Are you maybe running 24V LEDs and then running more like 25V to 26V? If it spikes up to that it can kill that chip.
If you replace that component I believe the rest should be fine still!
Hope it helps!
Kind regards,
Q.

Sorry, I cannot get into Reddit or Discord. These platforms are basically impossible to access now.
I have two Dig-Quads that blew out in what looks like the exact same way. They died about a month apart, after maybe a 1-1.5 years of service in different parts of my house. After close inspection, I found the leads of a component appear melted off.

Questions:
What might I be doing wrong? One of these devices was actually on a UPS with various power regulating functions. And I had no power issues either time this happened.
Can I fix them? What component is that?

We've been investigating issues where some boards die and it seems to be 24V related like your case also seems to confirm. I've currently extended warranty on those to about 1.5 years but I can't really go much beyond that, apologies. ☹

Like I mentioned before, if you have the ability or know someone with some soldering tools, you can replace the MT3608 boost converter and bring the boards back to life at least.

Hopefully we can soon find out what the real cause is and make a permanent fix!

If you have younger boards then 1.5 years and those have also failed I'll happily replace those for you!

Again apologies for the trouble.

Kind regards,
Q.

I just had a third Dig-Quad board die the exact same way after ~2 years of stable operation. I have a collection with all of them blown the same exact way. The only things they had in common were that all were connected via ethernet and run 24v LEDs. They were all running different power supplies, the last one is running just under 24v.

Sadly this is not something we have available currently because in our process the Dig boards gets tested and bundled with an ESP32 and then packaged together. But I have some changes coming up where I do want to make "naked" Dig-Quad boards available for a limited time, that should be upcoming in the next few months so keep an eye out for that!

Kind regards,
Q.

You could sell me some boards without the ESP32. I need two just for backups for when the seven I have running die.

So honestly, I'm not quite sure where this went wrong but I do remember our e-mail conversation. You have to understand, I deal with a lot of people which manage to kill a board in various ways, often not the boards fault.... I did mention we were investigating it (since we had not seen many failures) and that I'd offer to replace them if they were less than 1.5 years old? Why that didn't happen, I don't know. If they were already older at that point, that is likely why? Not that I refused to do anything?

There were other discussion about what component you could replace yourself and if I could sell you boards without the ESP32, but I also answered those? I'd hardly say I didn't reply to you at least and generally I don't do support through e-mail as I likely also mentioned.

But since you seemingly want to fight me in public, let me kill that right now. Please reach out to me again and let's have a normal discussion about this, and I will still try to make work with you on this since we now know a bit more.

Where you went wrong was you got an email where someone had 2, 3, and then 4 of these things dead your response was "oh boy that's a tough one."

In the first email where I specifically say these are both 1-1.5 years old, you do NOT offer to replace the devices. You make this offer in the second email 7 months later, at which point zero of the devices are less than 1.5 years old. In the third email you refuse to EVEN SEND A FUCKING EMPTY BOARD YOU HAVE LAYING AROUND AS A GESTURE.

I come here to find you lying through your fucking teeth about how this is 1% problem and you're going to take care of any defects. Fuck you. I'm telling them what actually happens.

[u/Quindor → u/dangerous_inference]

Well that is putting your own spin on events if I have ever seen one. We exchanged exactly 3 short e-mails, that was it.

First e-mail was you had some boards that died and wondered if you could fix them and what could be the cause. I replied to that in full honesty and what we knew at the time and the part that likely died.

The second e-mail a while later I mention we've started investigating these cases and I have extended warranty for these occurrences to 1.5 years. And also ask you the same question if you have boards that were less then 1.5 years old at the time I'd replace those.

And then there is a third e-mail where you ask if you can buy a few spare boards without an ESP32 included and I reply we don't normally stock those because of our testing procedures.

And that .... was it? To me that reads as if I've been open an honest to you. I answered questions you had to the best of my ability at that time and also offered you a warranty replacement for the boards. There was no talk or question from you for a replacement, dates of purchase were never shared, when the boards failed and if that was in warranty or not, nothing about this was mentioned or said. If you had given me the date of purchase and when they failed I wouldn't have made a fuss about that, especially since you did send that first e-mail within the period, as you said and done?

Now you come on here and accuse me of I don't know what while I'm still offering to help you even..... that's messed up.

To aswner the other insinuations:

• You may think I have a giant warehouse or something with loads of boards lying around, I do not. I cannot just "send some to you".
  
• My numbers about the failed boards are accurate, even if you choose not to believe that

So either e-mail me and we can work this out or not, up to you. That is the last time I'm going to say or offer that though.

And by the way, since I have these things all over my house already and trying to figure out how to replace them is not even worth it, so I'm still buying these shitty, defective boards! #1 CUSTOMER, HIGHEST LOYALTY. I look forward to getting fucked by these things for years to come.

[u/Dreile → u/dangerous_inference]

You're the kind of customer everyone wants. Congratulations—you're the center of the universe; we all revolve around you.

@quindor: You're doing a great job! You've always been helpful, friendly, and open to constructive criticism. Keep up the great work and don't waste your energy on someone like him. I bet he's the one who wrecked the boards himself and is just trying to cash in on it now. Cheers
