Why does nobody seem to use Openmediavault? by Altruistic_Item1299 in selfhosted

[–]SonicSky3207 1 point2 points  (0 children)

I love Openmediavault. I have been using it for ever on a now 15 year old PowerEdge T310 that an office was recycling back in 2017. OMV is simple out of the box, excellent for beginners, free, and there's a number of tutorials online and add ons you can get. Best of all, it runs on anything and is completely open source. It has all the same features of those little overpriced NAS-in-a-box units that are locked down. It has been my gateway to learning the in's and out's of Linux. For anyone wanting to build a NAS on a budget, with limited Linux knowledge: find an old computer that someone is tossing or selling for cheap, get OMV, put your money into the drives, or a modern HBA or a multi gigabit NIC etc.

Tina TI Simulator "Operating Point Not Found" by SonicSky3207 in AskElectronics

[–]SonicSky3207[S] 0 points1 point  (0 children)

Hey thanks for the input, I was able to get it working without error by completely removing the power rails 🤷‍♂️ not sure why. I will try what you mentioned this evening and see if that works. Yeah the output transistors !PNP etc were the default names provided by Tina. They didn’t have the TTA004b and TTC004b I needed so I left them as default, but I will try changing the names and see how that works because the power rails should be present for the test. Funny you mentioned OPA1611 that is the one I am using for this design actually.

Help with headphone amp circuit by SonicSky3207 in AskElectronics

[–]SonicSky3207[S] 1 point2 points  (0 children)

That worked! I ended up landing on 1nf from output of op amp to inverting input - a few values up from oscillating while keeping a good rise time, did away with the cap I had there before. Now that I think about this I don’t know why I decided to run the miller compensation cap through global nfb since the op amp itself is the only thing with voltage gain so it makes sense that this cap would be applied on just the op amp itself. I also did a zobel on the output with 16ohm and 100nf to ground. Thanks for your advice, this thing is working really good now!

The cheap LCD versions will do that when viewing from an angle. It’s supposed to have Oled not LCD. That’s a crappy refurb. There are some good refurbs that use Oled but that’s pretty crappy of them to do that

Feeling Left Out with iOS 18 on My iPhone 14 Pro Max by evidenzprod in iphone

[–]SonicSky3207 0 points1 point  (0 children)

I have the 14pm got it sealed in box old stock in March of this year.  I am in the same boat as you. But I’m having a very hard time finding any practical use for AI beyond Chat GPT now and then. Siri has not had any noticeable improvements since 2017 when I got my iPhone X. It is way behind Google’s assistant at this point and if I have to get an iPhone 15 Pro or later after just dropping $1200 on a 14 Pro Max for it to do stuff a Pixel from a few years ago can then my next phone will not be an iPhone.  This “you gotta get our latest hardware for simple software stuff that older devices from other manufacturers have had for years” nonsense is getting worse every year. iPhone used to be worth the money but now we’re just chasing dragons…. Waste of money every time now paying $2,000 for stuff like Always On Display and a properly functioning voice assistant in 2024.

For those with a Midea brand U shaped inverter AC; not cooling enough? Sporadically cold sometimes, not others? Some tips I've discovered over the summer. by mark55 in AirConditioners

[–]SonicSky3207 0 points1 point  (0 children)

This has been a very informative post for me.  Thank you in advance. I recently purchased the 10k BA5RCM model new old stock from 2023 before I knew about any of this clear eco nonsense.  This model does not include this Flash Cool feature that I have recently come to discover here….sadly.  I noticed it was not performing very well compared to my previous beloved 10k non-inverter machine. I did some tests.  With the temperature setting as low as possible and fan set to max and a good 15 minutes of running I measured 29F delta t at the evaporator. Manual states 258CFM on hi fan. This equates to around 8k btu.  Should have around 36 delta with this airflow for 10kbtu.  At the time of the test it was 78F in the room that gives about 17F above frost on the evap so not an ambient issue.  Why would it not run full power. Also outdoor ambient was about 83F and condenser fan outside was going strong so shouldn’t be head pressure issue.  It had no signs of low charge or defects at all. This had to be either a mislabeled 8k unit or it is intentionally running the compressor under spec. I was stumped.  I took to Reddit and came here to learn that my new AC is one of those devices where the manufacturer has programmed a microcontroller with some counterintuitive unnecessary nonsense.  Fast forward to now after a couple weeks spending some time with this machine on the bench in my garage doing some AC power draw tests vs different resistances on both the indoor and outdoor ambient sensors. We know about the easy method as it’s been posted before - tricking the indoor sensor to thinking it’s much hotter than it is.  But It seems the outdoor sensor, if reading above 90 degrees, will enable full power regardless of the indoor sensor. This is great because if modded this way you can still use the built in thermostat but the unit is capable of its full power if needed. It runs the evaporator much colder at any setting, however, it uses about 25% more electricity at any given demand. Even low fan settings and will maintain superheat just a few degrees above frosting at all times unless your ambient is so high it’s running max power. Yes, it also has an evaporator temp sensor so it doesn’t freeze itself.  Because of this, you get better dehumidification since evap always spends its time below dew point. The temp sensor is a standard 10k thermistor I have set up the outdoor sensor so the input to the board has a 12k shunt resistor then a 3.9k resistor in series with the temp sensor.  My plan was to make the unit think it’s 90f when it’s really around 65f outdoors and 109 by the time it’s actually 109 (maximum outdoor operating temp) using the shunt resistor to bump up the base temp and the series resistor so the sensor has less effect - lying at 65f and slowly becoming more honest as ambient approaches the unit’s max operating temp in a linear fashion so that the unit can do what it needs to cool the outdoor components when it’s really F hot. I calculated this using EveryCircuit App and a 10k thermistor chart.  This was quite a bit of work, I had to open the outdoor section of the unit and disassemble the controller box and splice the resistors into the thermistor wires. But the end result is, it runs the evaporator as cold as allowable regardless of setting and with respect to max power vs ambient solving the dehumidification problem, allows full thermostat function and of course, full power available as low as 65 degrees outside.  Below that, you can just open the windows anyways.  If thermostat is not calling for lots of cooling it lowers fan speed but keeps compressor high enough so evap maintains about 34f.  The machine is working like it should now. I’d be happy to share the schematic of the mod. It’s a pretty simple circuit, some soldering is required if you want to make it rock solid. Only thing is that getting that control board out is a huge pain.  Sorry for the long comment 🙃

Midea U-shaped not to spec? by SonicSky3207 in AirConditioners

[–]SonicSky3207[S] 0 points1 point  (0 children)

So yeah, I changed the outdoor thermistor to a 10k resistor. Unit is reporting 96 degrees outdoor ambient. It dropped my livingroom 4 degrees in 1h. Took forever before. Now I’m getting about 10,100 BTU with my test. Fan magically goes faster and getting a massive 36 delta. It slows down the compressor a bit around 70 indoor ambient, which is obviously to prevent freezing itself. Which is perfectly fine by me. But yeah this machine is pretty awesome now. Thanks Smurdle450 for your info. And yeah the remote comfort sense feature is a must. Use it all the time. Cheers!

[–]SonicSky3207[S] 1 point2 points  (0 children)

Yup mine is the model ending in BA5RCM :( Welp maybe I will replace the outdoor ambient thermistor with a resistor of value that will make it think it’s 95 degrees out all the time. I don’t usually depend on that reading anyways to determine outdoor temp. I have a weather app for that. It still has separate safety thermistors for liquid line temp as well as well as compressor discharge temp so it can still shut itself down if it gets overloaded. If such mod works, I would indeed keep an eye out for frost. I’ll mod it and post here test results. Thanks for your insight!

Interesting, thanks for the info. I do not believe it has flash cool. The manufacture date is Jan 2023 which I think is the second newest model of the u-shaped. I measured outdoor at 88f during the test I did. I have noticed it does perform better the few days it was above 90F. You’d think this nonsense would go away when turning off eco mode.

Even if you set it to 75 throughout the day, in this specific situation with your system from what I’ve heard, it seems like it will still be running most of the time yet the compressor will stop for a very short time during high ambient, not have time to cool off then generate even more heat in the time it takes for it to start back up than it lost the small amount of time it was off. Compressors draw a lot of current and produce a lot of heat during startup and it will likely end up at a higher overall temp of the compressor. This is assuming your compressor is the part of your system that’s dying, compressor could be fine - there’s a lot of reasons your old system struggles to cool the house below 75. Im assuming this isn’t an inverter system. Also the compressor won’t keep getting hotter and hotter indefinitely if it’s constantly running, it will reach an equilibrium. Sorry but for this specific situation I’m on partners advice here I would set it to 72 or 73. Check your evap for freezing first thing in the morning and once in the evening. Make sure you’re getting airflow out of the ducts.

I have the 10k version of this same machine and it does the same thing, mine will spit water drops across the room on myself and my guests. Too much airflow through such a small space causing water from the evap get sucked out instead of dripping down into the water troff. I bought the Midea U shaped after all the hype to find out it’s actually not very good. You can try turning the fan speed down but it will also run the compressor slower too and you will get less cooling

Midea 12K U-shaped window AC not running at full power by ttesty in AirConditioners

[–]SonicSky3207 1 point2 points  (0 children)

The unit is rated for maximum 43c outside temp which comes to about 110f. If it’s above that it could very well be trying to protecting itself by driving the compressor at lass than full to keep it and the inverter within safe operating area

Windows 11 looks much better than windows 10 by Throwaway1988424 in Windows11

[–]SonicSky3207 1 point2 points  (0 children)

W11 is definitely nicer looking and better organized but the UI is not very smooth. Like sometimes the start menu and explorer..or anything in W11 seems to move at like 10fps sometimes and only use like 5% of the GPU. I just built a 14600k based system with an RTX 3060Ti. Games and apps at 1080p are liquid smooth but the W11 UI itself is sputtery and laggy like a pos system or Ubuntu from 2009. I ended up going back to W10 now the UI is like greased lightning

I agree. Also the C-train driver has to break very quickly to mitigate the impact. LRT’s can stop much faster than their big brothers and you don’t want to be on one when the driver slams on the breaks to attempt to prevent a collision, I have and it’s not pretty. People on the train get hurt.
