Mine won’t turn on and when it do it’s had a ⚠️ on it

you may want to verify whether the fan rotor inside the device turns smoothly or if it may be jammed by something. If the motor doesn't turn freely it may need replacement.

You can update firmware through usb c, eliminates often problems with short circuit protection alert...

Yes - Make sure to wait a long time, when the LED flashing color changes when doing this, as doing so before will lead to the device not booting. It is fully recoverable however it appears

How does the firmware upgrade work 🤗 Does it work with android or PC and how, please? 🤔
@liminalsunset 3 күн бұрын
@@WaschyNumber1 I'm not sure about Android but I believe you have to hold down the power button for a few seconds while plugging the device into the computer, then it shows up as a USB drive that you copy the firmware into. You then have to wait a few minutes until the flashing light changes color before trying to turn it off/on again.

nominally 7.2 volts but can go up to 8.4 V when fully charged, min 6V when empty

Thanks for this amazing teardown! There is some charging bug on my unit. If I discharge the battery and charge it, it will charge to 4.2V with regular CC/CV. But if reconnect charging cable or start charging from not empty, the battery is charged to 4.4V. Weird.
@liminalsunset Ай бұрын
I've never discharged mine but it appears to charge to 4.4V. I assume the battery is a high voltage chemistry perhaps. It does seem to work better when charged to full.

can weld 0.2mm - 0.25mm thickness nickel plate to battery. such as product description advertisements ?
@ariesleo7396 Ай бұрын
If you play with settings the max is 0.2 pure nickel. Highest I recommend is 0.15 pure nickel.
@liminalsunset Ай бұрын
It already struggles with welding 0.15mm nickel plated steel to 18650 batteries. In order to get a good weld you have to press lightly and not too hard, and keep the probes close to each other. This was the difference between it never working and working well enough.

Hello Larry, Congratulations for this excelent video. One question, this us actualy a Xiaomi product?, why do not appear the orange “mi” logo on the box, nor on the product? I just bought one of this in Aliexpres and just yesterday I received, having the doubt where I have been cheated giving me an good imitation.
@liminalsunset 2 ай бұрын
the rounded M Mijia logo is a sub-brand of Xiaomi. Xiaomi usually only uses the orange logo for Xiaomi branded products and not the Mijia ones, similar to how Honor and Huawei are made by the same company but don't have the same logo

I found this device in non-working order, only green light lights up when USB charging and try to find any info how to repair it because it is so cute. No luck at all. The battery seems to work fine and is fully charged. Without battery and only USB connected, the system draws 170mA at idle, I think that is actually pretty high for doing nothing. It doesn't want to turn on. Switch seems to work, diodes checked, voltage checked, everything seems to be fine. What could be the problem? Somebody can provide me access to a service manual or circuit schematics? Many thanks for any reply.

This was a pretty niche device when I found it, and I don't think it would have been easy to find information about it. It appears to have been produced in limited quantities. I would recommend to maybe try changing PMIC.

It would be so nice if they added an extra power port and extension cord, so you could run of day a car lighter system. I think for the form factor it's a pretty nest device. I'm bit familiar with this form factor, so perhaps and probably there are better ones
@liminalsunset 2 ай бұрын
If I had to take a guess, the lack of a power port on the device is also intended to indirectly limit how long you can use the device at one time (i.e. to prevent overheating). It's possible that the device would burn out if you were to add this feature and operate it for an extended period of time.
@RomboutVersluijs 2 ай бұрын
@@liminalsunset but it then could easily have a timer or temp measurement, I'm just free balling. I understand this device has its limits die to its form factor. I think it's still a nifty device. I bumped into it today as a shop here on the island sells a 1s. But hen I noticed there is now a V2. That's got me googling and looking at reviews. I think I prefer the V2 and would order it online vs buying it locally

Insimply van not understand why they can't out in a much bigger battery. I mean my phone already has 5k mAh how can this have just 2k?!
@RomboutVersluijs 2 ай бұрын
I guess the battery is 2kmah because it produces more amp vs a phone. I'm sorry for dumb question, I'm not really familiar with this kind of stuff
@liminalsunset 2 ай бұрын
The reason for the capacity difference is that the batteries are two smaller ones in series, and in a phone there is effectively one larger battery in "parallel" so to speak. The amount of power stored is voltage times amp-hours. Thus, the battery in this device is actually equivalent to a 4000 mAh phone battery. The reason it is not 5000 mAh likely has to do with your other comment, because the power output (sustained) of these batteries is higher.

Thank for great video. And after watching, I got an idea to mofify the pump by adding connector with a switch that can bring external ~8V DC source to motor pump (12~15V to 8V DC-DC conversion). That will save energy from internal battery and extend use for car/motorcycle on the field. Of course, initial pressure (e.a. from 0 to 30psi) will be manualy controlled for multiple tyres and final pressure (e.a. 32psi) will be by switcing to integrated battery and automatic stop when wanted pressure is reached. What is your opinion for that?
@liminalsunset 3 ай бұрын
My opinion is that a better way to accomplish this would likely be to simply have a switch that allows you to power the device either from the battery or the external power source. This way all functions of the device are kept. As long as your external power source can supply 40 watts or so continuously, it will run fine. You should ensure that the battery is disconnected during this operation, as this charge rate is likely far too high for it. On the other hand, the battery power provided should be sufficient for most uses. As seen in the test, generally, charging for half an hour will be enough to fill one tyre of a car from empty.
@bstefano59 3 ай бұрын
I think that disconnecting battery pack and external powering whole unit with pump voltage (7.4V or above) will destoy charging and mesauring part of device. Also, my opinion is that unit is charged by 5V and battery is leveling charged for every cell. So thats why I suggest to external power pump motor only. I didn't open and measure voltages of my unit and that is why I asked you for optnion. Anyway, thanks for fast answer.@@liminalsunset

Nice clear concise video! I am a new subscriber! Thank for taking the time to make this video. I know just how hard it can be to make a good video, because I have made some terrible KZbin videos. I like to make videos, mostly for myself, just in case my fixing project actually works for several years and I might need to do it again someday in the future. I have posted a few on KZbin, but mostly they are stored in my video library. My system, which has 6 zone valve assemblies, was put into service in 1999. 2004 I replaced the first motor. Bought 2 spare zone valve assembly in 2004, since I figured another motor would eventually go. Lucky me, I still have 5 of the original motors working and I have that spare brand new motor I bought way back in 2004. Anyways, I think this looks like a nice little summer project I will attempt this coming summer in between weed whacking. The zone that seems to call for heat the most is our two back to back bathrooms. That was where the first replacement motor went. I wished I would have kept that motor to fool around with, but it is gone. I have noticed lately the motor for the bathroom zone seems to move very slowly when I check to see which zone is calling for heat. A couple times I think the lever on the bottom of that bathroom zone is not shut all the way. It seems the springs are not closing it all the way, so I really think it needs some maintenance. That is my long story, but I really think you did a great job explaining how to go about this. Great DIY video!
