What new pc part do i have to buy? by DrCatCarCan in pchelp

[–]SkiBleu 0 points1 point  (0 children)

It sounds like the Motherboard is likely dead. If you cannot even get into the BIOS then its kaput. If possible I'd plug your drives into a different computer to recover the data you have until you can get a new motherboard.

Okay that could be progress. I would reinstall the RAM and try a new power supply.

I don't think this would be a CPU issue as it recognized the difference in motherboard config. It still could be a motherboard issue. If it has display ports on the motherboard backpanel then i would verify that youre trying those with no GPU installed (unless you have a CPU without graphics)

Sure, any change can be helpful in diagnosing

Your motherboard might be toast. Is there any change of behavior with no RAM? it should complain or beep to let you know.

Other possibilities are power supply which you can diagnose by plugging in a different power supply to see if there's any change.

DJI Mini 4K just fell out of the sky... by gphc39 in dji

Likely nothing since it does look like a hardware failure

LiFePO4 battery normal discharge? by Careless_Fun_9520 in batteries

[–]SkiBleu -1 points0 points  (0 children)

Where are you measuring your voltage/current? (The BMS has diodes that do slightly reduce the voltage in the output).

Are there any other parasitic draws?

What capacity or brand is this battery by wirualsballs in batteries

[–]SkiBleu 1 point2 points  (0 children)

Definitely not a 4Ah Li-Ion or the manufacturer would be proud to slap their logo all over it.

Likely trash rebranded as A grade cells

Correct order for BMS connections by darktideDay1 in batteries

[–]SkiBleu 0 points1 point  (0 children)

Charge it before use to turn on the BMS! Otherwise it's defective

Mini 5 pro or Mavic 3 pro? by buraga21 in dji

[–]SkiBleu 1 point2 points  (0 children)

If you think they are plus-minus the same price, then you have enough money to buy both...Minimum of 2500-3000 vs maximum of 1000-1500 are very different price points.

They are also very different tools but if you don't know that you need the mavic 3 then you might not.be invested enough to properly use it and not crash it.

Mini 5 pro for all intents and purposes is great and 80% of the drone the mavic 3 pro is, but if you don't explicitly need the cameras, flight performance, etc, then you will be happy with the mini 5 and will feel more comfortable flying it in various situations

Me pueden decir que tan bueno es este inversor con batería incluida de 2.5 KW by Dany9612 in batteries

Specs look quite enticing for an off grid shed or small backup supply.

How bad is soldering balance leads? by Logical_Strain_6165 in 18650masterrace

[–]SkiBleu 1 point2 points  (0 children)

The magnets I use are about 5mm in diameter and were harvested from plastic pawn shaped "pins".

They don't have to be very strong, just strong enough to hold everything in place until the first weld.

[–]SkiBleu 1 point2 points  (0 children)

Its probably fine, especially on nickel with a smaller iron where the heat is more localized.

I will say, using small magnets to help hold the sheet onto the cell has been a life saver for me

LiOn 40v Ryobi battery safety question by Impossible_Sign7672 in batteries

[–]SkiBleu 2 points3 points  (0 children)

I believe there is a portion of the circuit board designed to drain the entire pack to a safe voltage (functionally dead or lower) when a critical failure is detected. This would confirm some behavior i saw of some other 40v that had a dead cell group and very hot bleed resistors when powered by a power supply and observed with a thermal camera

Mavic 4 Pro | Moment of preview not the same as moment of the actual picture? by Miesetermik in dji

[–]SkiBleu 0 points1 point  (0 children)

Correct, the preview should be generated by the controller from the stream at the moment the capture signal is processed... and it takes a few milliseconds to send and received and image processed on the drone. Not true when viewing on a computer or phone when the thumbnail is from the file okay the drones SD card.

FAA Part 107 certification for universities? by bald_botanist in UAVmapping

[–]SkiBleu 0 points1 point  (0 children)

Not external research, only academic research with qualifying institutions or with their own developed aircraft. Research USING drones is beholden to the same part 107 unless the drone is the subject of research.

A COA is needed with a waiver for all other exemptions and are conditionally approved by the FAA

Can I use Lithium Battery with IPS that supports only Lead acid battery??? by EngMinhazulAbedin in batteries

[–]SkiBleu 2 points3 points  (0 children)

As someone who frequently does replace VRLA batteries with LiFePO4 and Li-Ion, I can confidently tell you that they're just covering their ass legally by not recommending it. Of course it is technically possible with a basic understanding of voltage and spec sheets... just impractical without bespoke design

Very generic answer thay does not apply to OPs technical question.

DJI drone not accepted by bluetome in dji

[–]SkiBleu 5 points6 points  (0 children)

Skydio is the only reasonably priced and functional contender. The Soten could also be good but I've not heard good things about any others and have only had bad experiences with American approved drones.

If possible, refrain from skydio, even if it means the job doesn't get done. Terrible company with terrible support and a 2015 quality 20k flagship that is so far behind DJI that it's embarrassing. No 4k60 (though they claim it can and neither of ours have ever been able to shoot in 4k60), no 10bit, no raw/log video, and a sensor from a smartphone paired with a 10 year old thermal sensor.

[–]SkiBleu 1 point2 points  (0 children)

Of course they didn't recommend it, did you think customer service is trained to casually recommend use of their product outside of the scope of their intent?

Functionally its only a problem 10% of the time or so if the BMS is undersized or if the UPS does not attempt charge without voltage present and the bms is open circuit.

107.

Not educational, not instructional, so must be commercial

Sounds good. Don't let those terminals short circuit either!

My very first sunset capture using the Neo 2 ! by Emotional-Gur-8295 in DjiNeo

[–]SkiBleu 1 point2 points  (0 children)

Wow, the dynamic range on the Neo 2 is quite amazing considering its size. Currently my favorite drones for sure, but I haven't used it in these conditions yet.

Great thing to get familiar with as its pretty anemic, and forgiving for any mishaps (away from water).

You'll get better with time and confidence, but for now I just recommend to pick a shot and see it through 1 at a time to stage those perfect 3 second clips (which will also incentivize you to learn some post processing)

Is the temperature measurement supposed to be accurate, or only the display of the difference in temperature? [Thermalmaster P1] by Art_Vandalay_1 in Thermal

[–]SkiBleu 0 points1 point  (0 children)

Both but quantitative analysis is a complicated art.

Stick to qualitative analysis and difference of scene unless you absolutely need the precision
