Hi! Thank you for watching and pointing this out. Yes, indeed, there are lots to improve. I still experimenting with different microphones, and I hope new videos will have better sound quality.
Hi! I'm using my own designed/built device - ESP32 as a controller and NPN transistor with a 10W ceramic resistor as a load section. Maybe later I will make a video about the tester device. About the price - I don't include this into my videos because the price is constantly changing, and after several months this will be irrelevant. And if you're in another country - it might be irrelevant for you at all :)
Muj Zenit km+fotografuje skvěle ..U Pentaxu se mi vylámal vnitřek,nehledě k tomu že muj Zenit má přesný Expozimetr..Zenitu jsem měl mnoho,...Zenity KM dobře znám,některý kusy se musí trochu vochodit...
Well, from the definition, a disposable camera should only last for one roll of film. Because it is, well, disposable :) So yes, they don't last long, this is expected for the disposables.
Great Video am happy with the Comparison you made , Can you compare Lithium AA battery with another brands (VARTA Ultra Lithium VS ENERGIZER Ultimate Lithium VS GP Lithium VS ..... )👍
it's odd that zenit was still making film cameras in early 2000s.Although we still used film until about 2008 because digital cameras were not so high resolution until then but i thought that zenit was far gone with soviet.
No, and actually KMZ (the plant where Zenit cameras are produced) before the war produced a digital camera, and they still make various types of lenses.
i use an 1.5v zinc carbon AA battery to charge for the dead ni-mh AA battery for about 30 seconds and the ni-mh came back to life.The crystal inside short the battery so it won't get charged until we apply a high current to melt that crystal.And maybe we want to remove the battery nylon covers.
So, there really is a difference between the Industrial Pro and the Longlife batteries. I read elsewhere that these are identical but packaged differently for OEM supply.
Are you draining NiMH to 0.69 V ?? How many times have you done that to those poor things before putting them in test? Basically you irreversibly degraded the battery, after which there's no point checking capacity. Also there is no point testing charge down below 1.0 V. 🔋💔🪦
You can discharge single cell to 0 Volts, and with small discharge/charge current this will not lead to significal damage. Hovewer, if you will dischage a battery (several cells in series) of rechargeables in that way - you most likely will kill cells in a few cycles - because in a battery weakest cell will be reverse-voltaged in that case. But with single cell this not just harmless, slow discharge to 0 can actually recover some capacity of old cells (but not much, they will not be like new).
A common failure for 27 <= 2011 iMac lcd backlight blacking out is the actually lcd led backlight bar connectors poor solder. Requires disassembly of entire lcd screen.
Hi there! Thanks for your comment! If you want to have a simple point-and-shoot camera, please consider getting one with adjustable aperture and shutter speed. All (reusable) disposables will be more or less the same - just because they all have a shutter speed of about 1/100s and a fixed aperture of about f/10.
so according to your test results, the best non-rechargeable battery is GP Ultra Plus? What about in low power, long use type of devices like electric door locks?
Hi there! Thank you for the question! If the cost is not a question, and you need the longest lifetime (for example, in some sensor where it is problematic to change the batteries) - lithiums will be best. If the price is also important - in my opinion, the cheapest alkaline will be the best choice. Thank you, and have a nice day!
@@dmitrysysoletin9967 yes that 's true. For high power drain I use ikea ladda 2450mah, for mid drain alkalines and for low drains zinc carbons. I found some really good deals with zinc carbons, like 1€ for 10 and they last long and never leak even when dead
Hi. Did the Tinker Board v1.0 upgrade and have had no problems, except the speaker - clicks and pops with latest tinker OS. I’m going to add Orange Pi 3B and see what I get. Orange pi has 8GB RAM & 128GB eMMC drive. I’m posting to Pi Top Forum. Thanks, Ian
i have the same imac but my imac randomly the screen turn black and still on bcs i have a second screen for solve this i need to clear the nvram (cmd+ alt+ P+R) and works one day and do the same nesxt days. you think changing capacitors can solve this?
@@maniekkozlowski Yeah is totally black and When I press power button the screen is back but later turn black again, you can solve this changing the 4 capacitors
Sheesh. I was already nervous about fixing the backlight issue myself. Which is why I bought the parts almost 2 months ago and still haven't used them. Now he says don't touch the power board because it's deadly even when the computer is unplugged. Well, now I'm absolutely terrified!
Yes, there are capacitors on the power board that can hold a charge (they charged to rectified mains voltage, about 310V in 220V countries) for a while. So to stay safe, disconnect the power cord in the evening and start opening the computer in the morning - give it time to discharge. About the backlight - well, if yours is broken anyway, why not try?
you can just discharge them. unplug PC, and Hold the powerbutton for some minutes. You can double check the caps with a voltmeter. anything below 50v will be safe. if still above you can hold the button more, or just discharge the caps with a resistor
hi, i bought a new led board and replace it, it was good for 3 months then it start again, do you think its because of this condensators really? and do you have a link for them?
Hi there! Can be lots of reasons for that. Bad capacitors is just the easiest one to solve, and for me, it helps :) No, I don't have a link. Just bought some caps in a local radio store. You can do the same, just select ones with equal voltage and equal or higher capacity. Low ESR ones are preferable, and the higher the temperature rating - the longer they will work.
