Freezing winter and boat lift battery with solar panel   - Page 1

content: I have a boat lift with an electric winch powered by 12V lead battery. It has a solar charger integrated with the control electronics, which have a switch to disconnect all but solar charging. This is Minnesota, where we can touch -30F or even lower. I tend to believe that it is best to leave battery and charger in place, outdoors. The alternative is to remove and store battery, unattended, in unheated garage which may see -20F.I will appreciate any words of wisdom on this subject ?

content: If the battery is in good condition and fully charged it will survive -30 deg F. However if it is only part charged it wont and you need to be 100% certain that condensation and icing wont cause a discharge leakage path across the terminals. IMHO its best to pull the battery, wash and dry the top to remove traces of acid and contamination that may provide a discharge path, fully charge it, clean the terminals and lightly grease them with Vaseline, then dry store it in the garage, and give it a top-off charge before refitting it in the spring.

content: It should be fully charged, it is 4 months old, kept on the solar charger. I think I will remove it, wipe it clean and store it under the garage bench over a piece of wood. On the spring I will hook it back to the solar charger.Thank you for the advice.

content: If your panel gets snow on it, there is a chance you get nothing charging but instead lose charge in the idling solar charge controller.I've been burned by solar charge controllers, specifically Morningstar units that have around 5mA quiescent current and will not initiate charging into a weak/dead battery even in full sun. Terrible design.

content: you may want to search peoples general experiences with "maintenance chargers" in general (not just solar ones) search that on the net. they seem to be more of a hassle then there worth frankly. a bad one will ruin your battery and these days, who trusts some off brand solar charger to do it right..Even though fully charged lead acid batteries should be good over the winder outside, i always brought them inside for the winter. and i never used a maintenance charger. I'eve just always jsut made sure they were fully charged before i stowed them away.I've had bad luck leaving lead acid batteries in unused equipment over the winter. Even for equipment stored inside over the winter, i disconnect one of the terminals over the winter months.

content: The same kind of thing happened in my company. A tech left an unencryped flash drive with proprietary information, including a computer image behind and it was found by the client. It raised quite a stink and, as a result, the company has issued all the field service techs Aegis encrypted 100Gb flash drives. After keying in the numerical password of choice, you have 30 seconds to seat the drive in a computer or it locks back up. 3 failed attempts locks the drive for 20 minutes I believe. I now have an encrypted USB hard drive for all my backed up information as it exceeds the capacity of the flash drive after having that hard drive unencrypted for years as it never leaves my home office.

Need Help Determining Actual Wattage of Cheap PSU - Page 1
Forum section: electronics / general

author: SuperShermanTanker
author_rank: Contributor
timestamp: October 29, 2017, 05:37:04 am
content: So I have this PSU from my first ever PC build back in 2015 and that was before I learned how cheap components can cause things to not work properly especially when it's a sensitive PC component. There is nothing wrong with the unit I have but for safety reasons I pulled it out of my main workstation and only ever used it in lower powered test machines to test out a certain combo of hardware in never pulling more then 300watts through it. It's a 700watt Apevia branded PSU in it and I have only used it for about a year before I upgraded to a better 750watt Corsair branded one then a 760watt 80+ Platinum Seasonic unit. I still have this neverending question in my head though about this original unit can it actually do 700watts or if now how much can it safely do and for how long. So if any of you can help me determine that that would be very helpful in determining what it can do and if I should even keep it. I attached some images of the PSU. I can probably link some higher quality ones if asked but I compressed certain ones to keep under the file size limit.

Options to save data in non volatile memory - Page 1

content: Hi, I'm working on a STM32F429-Discovery board and I wonder if you can give me your recommendations about the best method to store data in a non volatile memory considering that this board doesn't have an on chip EEPROM. The options I have are the followings:1. Store the variables in FLASH, although I've read that it can damage the FLASH memory.2. Storing variables in BackupSRAM registers. I have 4KByte, and to work it only need to have a battery connected in the 3V pin entering the chip in an Low power mode. It suppose to simulate an EEPROM but actually it doesn't because if theres no battery connected there, the information is lost.3. Using an external eeprom programmed by i2C.Hope you can help me and give me your opinion. Greetings!

I will add using an external serial SRAM with battery backup.If I was especially paranoid, then I would use two separate devices to store redundant data both in one device and across devices like two serial EEPROMs or two serial FRAMs. I might even place them on separate serial buses.

The project compiles but it doesn't do anything related to UART, SPI or the other definitions that I'm adding. Do you know why? The project that I had built was made with STM32 CUBE MX, and Im adding all the code missing in the eeprom emulation based on the CUBE MX project, but I don't know why it doesn't work.

Although I think we're getting out of General Chat territory and into things that ought to be in Microcontrollers & FPGAs.Were the other peripherals working before you added the EEPROM functionality? Did you make sure that the linker isn't placing any program data in your EEPROM emulation region (which will get clobbered when you save EEPROM data)?

Ultra160 controller not detecting full drive size - Page 1
Forum section: electronics / general

author: Ampera
author_rank: Super Contributor
timestamp: October 30, 2017, 10:12:22 pm
content: So in my new Pentium Pro machine I decided to go with a SCSI controller for hard drives, and I have the Adaptec 29160N controller card.Cutting to the chase, my issue is that it doesn't detect the full drive, but this is with a twist. The size detected changes proportionally to the actual drive size. Let me explain:I originally wanted to use a 147GB Ultra320/SCA80 15k hard drive. I have the proper adapter, and the drive was set to ID:1. When I booted the machine, it detected the drive as being 9200MB in size. This is red flag close to a certain LBA limit, as well as some other INT13h stuff, whatever, my first thought is that it wasn't doing the LBA properly, but I do not believe that's the case.I switched the drive to a 73GB Ultra320/SCA80 10k hard drive. This is half the size, and when I installed it, the card detected a size of around half of what the other drive was stated as.It got even stranger when I tried to use the integrity checking tool. It started checking the drive, and the little text mode progress bar went up and the number kept increasing to 100%, and when it got to 100%, it kept going. The progress bar kept increasing until it eventually wrapped to the next line of the screen. This is somewhat obviously evidence that the card is addressing the entire drive, but not detecting it properly.Before I go any further, these drives are KNOWN GOOD. They have been operating in a considerably newer IBM X-Series EServer model 235 where they worked absolutely and perfectly fine.I am currently formatting the drive in DOS. It reports it's formatting 4.5GB, but with an Ultra160 controller and 10,000RPM drive, it's taking so long as to seem like it's formatting the entire drive.I have no clue why this could be happening, and it seems to be a bit beyond a simple driver issue. Any help is graciously appreciated. The cable IS terminated properly, and it's 68 pin cable going through a 68-pin to 80-pin SCSI converter card.Update: The drive formats to the full size, so I am going to see if it will work fine all the way through.

I know we all start somewhere, and lets face it, our families don't usually appreciate the amount of equipment we set up (understandably I guess).And then it occurred to me, is there such a thing as a community electronics lab where everyone splits the cost and rents a bay rather than a whole office? It would be so much cheaper for those of us (like myself) who can't afford a lab, somewhere we can go to meet like-minded people, help each other with projects, share ideas, and generally have a good time doing what we love?I live in the South-East of England (UK) and I haven't found anything like this where I live, but I'd love to know if you guys had the same thoughts on the idea? Perhaps there's not a high enough demand, maybe it's been tried before?

It's more like oscilloscopes and multimeters and power supplies, just enough to build a cool robot or whatever.

content: Sennheiser G3 transmitters are capable of higher power for models programmed for other markets (like USA). But the European Union has determined that it is not safe for Europeans to have a transmitter strapped to their body that exceeds 25mW. Here in the USA, I believe the limit is 100 mW. And you see what that kind of radical RF radiation has done to us!

content: I would ignore the transmitter in the first instance and pay attention to the receiver and its aerials (There are much bigger wins to be had here).Using good quality Yagis cut for the correct band (Not broadband ones) with a diversity receiver and GOOD quality coax is a major win as much for the reduction in potential interference from behind the aerials as for the increased signal strength. You can gain much more here then the 6dB that is the difference between 25mW and 100mW, and it does not hurt your battery life.Note however that preamps (unless carefully selected to make up cable and distribution losses) are usually not a win, they tend to increase the sensitivity to overload as much as they improve the RF noise figure.The power limits usually have more to do with limiting the interference potential then any health concerns (After all a cell phone can put out a watt or so).The OEM will have set up the transmitters to suit your licensing regime. In the UK it is 10mW for a handheld and 25mW for a body worn pack unless you make special arrangements, not usually a problem.I have licensed 5W portable link transmitters before now, but that is kind of specialist.

This was annoying enough, but when I inspected the elements I found some piece of javascript was loading ads over and over. It was also generating errors - hundreds of errors at the start, and then 10-20 errors per second forever afterwards.I saved a Google Chrome "complete webpage" view of it in case you want to inspect what happened. But in case there's a ton of shit that is personal to me I wanted to pass the file in a private way.If you're interested, please let me know where I can upload this set of files.Besides the music and video, the most distinguishing thing about the ad is that it has "Ads by" and then a large triangular logo (like a play button with a swipe through it). But this didn't seem to have a name with it in the HTML, and I couldn't be bothered to find out what company it is.edit2: It goes without saying that there's an outside chance that this ad was delivered to me locally, or through man-in-the-middle. So nobody blame anybody until there is follow-up.

One works on 315Mhz while the other works on 433Mhz yet they still interfered with each other for some reason. Anyone have any idea why that is? In the end I was able to find a way to keep them from interfering by making sure I was never in a scenario where both were transmitting at the same time.

OK, it doesn't sound impressive enough, this one is totally overshadowing the one which resulted the Nobel price.Now we know the Hubble constant, know a lot more about the dark energy/matter, and who knows what else. It is a quantum leap in cosmology (pardon for the pun).

USB hubs with Cypress/TI/NEC chips - Page 1

timestamp: October 14, 2017, 11:33:35 pm
content: Is there any high quality USB 2.0/3.0 hubs that are actually 100% compliant with USB specs?I have some cheap hubs with VIA chips, but they don't work as expected.Basically, for 99% of the population, they work fine, but they are not behaving like a real Intel root hub.For instance, some hubs don't isolate port traffics, and a port can see data traffic of a different port.Normally, this is not an issue because a USB device will just not process bus packets that doesn't address its own address.But for me, since I write device side USB driver and I use hardware USB sniffer, it captures a lot of rubbish data and sample buffer fills up pretty quickly.Also, most cheap hubs don't provide fast, MOSFET-based current limitation, which in the worst case can cause port damage if target board has a short.So the question is, is there a really compliant USB 2.0 (or better 3.0) hub that behaves just like chipset's native USB controller?I'm not going to pay the price for a super industrial hub designed for German CNC machines, but I'm not targetting $20 shit either. My budget for a good, compliant 4 port hub is $100.PS: no ASMEDIA, my mobo has an additional ASMEDIA USB 3.1 controller and the ports are absolute rubbish. Stability is like shit.

content: Quote from: blueskull on October 14, 2017, 11:33:35 pmThis is actually the way USB hubs work. Downstream traffic is broadcast to all downstream hub ports and only the addressed device responds. A USB hub then works more like old-style Ethernet hub, rather than a switch, which does not pass on traffic to a non-matching subnet.Therefore, if you hook up a USB Protocol Analyzer to a port you may see downstream traffic intended for a device on another cable segment (connected to another root port). Use the filter functions in your protocol analyzer to filter such "ghost traffic" out and you are good to go.If you want to avoid seeing ghost device traffic, then use a dedicated USB host controller for the device you are debugging and capturing data from./John.
