June 2024, I just purchased this light and it is made different now. Looks the same, but the battery inside is different, I'm guessing because technology is always improving and changing. Anyway, if your considering buying this light, here is my experience with it. You still have to charge it 24 hours for the first time you take it out the box. No big deal, I plugged it in and forgot about it until the next day. Then any charge after that, takes about 8-10 hours. I use the light bar in a dark closet so it's not like I'm turning this thing on every day and leaving it running for hours. I might go in the closet 3 times a day for a few minutes at a time if that. So when it's fully charged it stays very bright for over a month without having to recharge it. Also, I did not use the screws that came with it. I went to Walmart and bought some of that 3M double sided sticky tape, I think it was $3.97 for a roll of it and I got the one rated for 15lbs of holding strength. I just cut a strip of that tape off and stuck it to the back of the light and then stuck that to the wall. Holds easy, no problem and I can always remove it if I want to. Lastly, in my instructions, it says you can just leave the light plugged in all the time and it will run the LED's continuously. So if your hanging the light near a plug, you could just leave it plugged in all the time. It does say to not run the light while charging, but that is because if it's plugged in and you turn the lights on, the power goes directly to the lights and not to recharge the battery. If your not using it wirelessly, you can just leave it On and plugged in and you will have light all the time. Just know if you turn it off, it will take 8-10 hours to charge that battery again. I like mine as it gives off plenty of light for a dark room. There are more powerful wireless LED's on the market, but I liked the fact that this one is a long bar, so it spreads the light out and projects it to a wider area in the closet. For reference, mine was $19.99 at a Ace hardware store.

Hi I m trying to simulate fuse behavior want to add fusing current vs time characterstic can u help me with the same?
@EETechStuff26 күн бұрын
First you need to plot the current thru the fuse, and then calculate RMS. Then square the RMS and multiply times the simulation time to get I2t, which describes total energy thru the fuse (see my video on Understanding Fuses). Each fuse time-current characteristic is defined by the I2t, so get the I2t from the manufacturer and in your simulation compare the actual I2t value vs. the fuse I2t rated value, and if the actual exceeds the fuse rated value at any time in the simulation the fuse should blow. Maybe make the I2t calculation as a voltage source and feed it to a voltage controlled switch (see my video on LTSpice switches), and make the switch operate if the realtime I2t volts exceeds the mfr. I2t. Haven't tried it, but something like that should work.

This ZMPT101B module seems poorly designed for use with 120VAC circuits and a 5VDC Vcc rail. The LM358 op amp used doesn't have enough output voltage swing. An LM358 output only swings from (Vcc - 1.4V) to (Gnd + 0.1V). For a 5VDC Vcc, the output can only swing from 0.1V to 3.6V. With the nominal output voltage biased to 1/2 of Vcc, the output will only swing from +2.5V to +3.6V for the positive cycle of the AC waveform. I wonder how well this ZMPT101B module would operate if you replace the LM358 with a pin-compatible rail-to-rail op amp like the TLV2462 from Texas Instruments. The TLV2462 output can swing from 0.1V to 4.9V when operating with a +5VDC Vcc. Some other tweaks to the gain setting resistors on the module might be necessary to get it to operate without clipping the output. It might be better to just harvest the ZMPT101B transformer from one these modules and build your own circuit using a TLV2462 op amp so that you can properly select all the components. The TLV2462 comes in many package types including DIP and SOIC. Cheers.
@EETechStuff28 күн бұрын
Did you actually try it, or is this just hobbyist speculation? In part 1 of this series I show how, after properly calibrating the ZMPT101B and Arduino Vref, the results match my voltmeter within less than 0.5 volts from a 120VAC wall outlet. Are you measuring something that requires more accuracy than that? Seems pretty good to me for a $2 USD device.
@N2Stooges28 күн бұрын
@@EETechStuff I haven't tried it yet but plan to do so... parts are on order. I want to run the modified module with a 3.3V Vcc and interface it to an ESP32 uC without using any additional power supplies. If the modification doesn't pan out, then I'll design my own circuit using the current transformer from the module. I'd like to be able to measure AC voltage up to 140VAC RMS with a resolution of 0.1V or better. That should be doable with the ESP32 12-bit ADC if I can get 3V of dynamic range out of the module. The TLV2462 is characterized at 3V Vcc to swing from 0.1V to 2.9V so it should be able to swing 3.1V at 3.3V Vcc. The TLV2462 Vcc range is 2.7V to 6V unlike the 3V to 36V range for the LM358 so that is a limitation I'm willing to live with and is fine for ESP32 and Arduino (ATmega328) microcontrollers. Thanks for your videos showcasing this module and your code. They were very helpful and provided great insight into the limitations of the ZMPT101B module and creative ways to use it. Awesome!
@EETechStuff28 күн бұрын
What makes you think the current transformer is accurate and linear enough to support 0.1 volts accuracy? And are you aware that typical voltmeters might have an accuracy of around +/- 1%, which in this case might be over 1 volt? My results show an accuracy for this module of better than 0.5 volts. So I'm not sure why you think it's "poorly designed", and why you think 0.1 volt accuracy is needed or attainable. But hey, have fun with your project.
