Re: Water Leak

BTW, the Streamlabs link I posted above now does show the in line water flow sensor with integrated valve and auto shut off feature. They use ultrasonic flow sensing and have proprietary firmware to identify small leaks. This wasn't yet available when I first posted. Its the same company that makes ...

Re: Print Issues

Printing from an ink jet or color laser might cost nearly as much as the print edition in supplies to make your own especially if you consider the cost of the printer in addition to toner and paper. There are lots of options for E reading. Blue light filters in settings or in screen protestors can h...

Re: Easy to Use Home MP3 Player for Older Person

Yes, Alexa with a prime membership with Music Unlimited will run you about $225 per year plus the device. Apple will cost about half that because you don't need the prime membership. The Android play store has many Jukebox apps, I haven't tried any but after all her CDs are ripped, this would be the...

Re: Easy to Use Home MP3 Player for Older Person

Both Alexa devices and Facebook portal can play music with voice commands from cloud libraries or I heart music, Spotify, Pandora etc. If she is not too connected to her own library, this is the easiest way to go and you get other features too. Google and Apple also have Smart Speakers, I think this...

Re: Question about Fast adaptive charging

I got that USB meter and it was useful in several ways. The biggest thing I learned was that the USB cable is every bit as important as the charger and load. I found that with a longer generic USB cable, I was only able to get 435mA charge and the slow charge warning but when I changed to a short 6 ...

Re: Cheap china led strobe lights. - need advice.

"Yeah most items made in china are knockoffs." Maybe not Most but certainly a lot the cheap stuff you find on Amazon, eBay and Alibaba. The same stuff they sell in the electronics malls in china but we get the factory rejects while they keep the ones that work. Did you see the CNN story on the count...

Re: Question about Fast adaptive charging

"the 2nd item on amazon is decent looking." I agree, I just ordered one for myself for Christmas. I have several older V and I only meters (we were giving them to customers at trade shows) but this one has a lot more features, sort of like the "Kill-A-Watt" but for USB devices. I found it for $1 les...

Re: Led Driver selection help / advice

Scanning Digikey, the vast majority of shift registers are 8bits, some in small packages, but Microchip has some interesting 64 bit chips with Voltage level shifting that you might be able to make use of. Here is one, others are in the same product family with varying bits and output max voltage I s...

Re: Question about Fast adaptive charging

The Negotiation between charger and device is all Analog. A managed device can throttle the charge current to maintain safe charge temperature and prolong life according to the manufacturers firmware. The adaptive charger responds to the change in [device] charge current [limit] by adjusting the out...

Re: Led Driver selection help / advice

The TPIC6B595 is a shift register with Open Drain outputs, Did I find the right one? Why don't you just cascade several of them to get enough outputs. Maybe you can find a CMOS output shift register with enough power to drive the LED without the open drain. A 74ACT family chip should be able to ligh...

Re: Question about Fast adaptive charging

We buy replacements because we lose them or need spares for travel or just different rooms. Since the Koreans don't particularly get along with the Chinese, I can't imagine an authorized Samsung product not make in Korea. They make the empty statement to use the charger that came with it because tha...

Re: Question about Fast adaptive charging

I use one of those USB Voltage and Current measurement dongles. You can place it between any device and charger on the USB cable and measure actual charge current and voltage. I have been known to sample several wall warts and chose the one with the highest charge rate at any given time. One thing I...

Re: Cheap china led strobe lights. - need advice.

"No such thing as quality from China...." Even the Chinese avoid made in China for many products. The reality is that ebay and amazon have become a dumping ground for knockoffs and end of run rejects. Amazon has cleaned up a bit but ebay is still no better than Alibaba. In any case, LED for Automoti...
