content: The weekend in nearly upon us and we now have a bit of time to do our own thing, so on that basis, who has plans on buying a Rigol product this weekend, and more specifically what product?The DS1054Z is still immensely popular with our customers but what else is grabbing your attention?Do you think the carry cases are worthwhile? And what's your thoughts on the two new products that Rigol have released? DS2102E & DS2202E.Who's looking for a Rigol Power Supply? Any new products that you would like to see Rigol release?Have a good weekend everyone!Mike

content: Quote from: RigolOnline on September 15, 2017, 10:07:24 amDear Mike,A couple of years ago, we bought Rigol's flagship: the DS6104, including most options (uart, spi, i2c decoding etc.).When we started to use the remote connection (via LAN), we hit the following three bugs:bug no. 1: (reported at, and confirmed by, Rigol in October 2015)When I run this software:https://www.teuniz.net/DSRemote/and select LAN connection,I get randomly the response: "command error". This blocks the connection for 5 seconds and a timeout occurs.This happens randomly, and when it happens, it does after sending different commands.So, it's not related to one and the same command. Sometimes the program runs fine for minutes.bug no. 2: (reported at, and confirmed by, Rigol in Januari 2017)Apply a squarewave of 1KHz to channel 1.Set triggering to normal, rising edge.Set the memory depth to 1.4Mpts.Acquire the signal, then set the scope to STOP mode.Download the waveform in RAW mode, format BYTE.When you observe the downloaded waveform, the triggerpoint isshifted about 460 nanoSec.bug no. 3: (reported at, and confirmed by, Rigol in December 2016)When setting the treshold for the UART serial decoding,it seems to work fine.But when asking for the threshold setting, the value is always 10% ofthe actual value.This bug happens when the probe attenuation is set to 10:1.These bugs are still unresolved and make it impossible for us to use the remote connection.So, when we talk about Rigol, this is what grabs my attention.Have a nice weekend.

Ideas for an ocean rover? - Page 1

content: For a while i had an itch to build something like a space probe. A remotely operated, mobile device located in some interesting environment.Problem is, any place with communications would have human erosion (stealing of the device), so the itch never quite went anywhere.However, i recently found that there are relatively cheap Iridium satellite modems available these days, and the idea solidified.A buoy kind of a device, free-floating on ocean currents. Solar powered, with a satellite modem and some sensors.So, the question is - what sort of sensors would be worthwhile to put on such a buoy?Is there a way to measure plastic mist content of the water?Is there a waterproof way to measure temperature, pressure, wind speed?Would it make sense to measure background radiation levels?Something else?Basically, given such a buoy what sort of sensor would you have put on it?The data balance is on the order of one kb per day (the price is about $1/kb, and the thing should hopefully last for a year or two).

When I worked for an aerospace company back in the very early '70s, there was a group we called the Buoy Group and every day one of their people was in the computer room plotting out wave heights and wind speed. I think they also measured salinity.Long before GPS, long before much of anything, actually. I never asked questions about the project or anything else. I was lucky to be allowed access, no point in pushing my luck.

wireless charger - Page 1

content: I had an idea last evening which I want to share. Maybe dumb. We are all seeing new wireless charging solutions everywhere. They may be wireless but they are still not contactless. You need to put your phone on something eventually. Why not make a mat with grid of metal squares connected to some 3 state buffers. And on a phone, two of its down edges, make them conductive. So when phone is placed on the mat, inputs connected to the pads are searching for a phone and deciding which pads should be connected to power.And we have literally wireless charging and it does not matter how you put your phone on the mat, just throw it on the table (like we all do) with mat on it and it will charge up. Easier than positioning phone exactly over the coilIts a metal to metal connection so we can charge at high currents, even phone cases wouldn't be a problem if they start to make them with conductive edgesexposed conductive pads on a phone can lead to some problems, electrostatic protection etc.What do you think about my idea?

If Amazon won't work with an Apple sanctioned device and Google Phone - what is the use? Up to now - only USB seems to be universal - except for apple which seem to be too taxing for engineering to have a USB...There is a company working on a laser charger. Walk into a bar and it directs a few watts at your phone. Safe when used as directed.

content: "The Wall came down in 1989"I know this, I was there after driving all the way from Frankfurt to Berlin so that I could join in the party.Most of my tools are housed in a converted Samsonite briefcase and every couple of years I go through the case and remove items that I have not used. I don't have three or four different sets of screwdrivers, I have one set with exchangeable bits that is enough for 99% of my work. There's also one set of pliers in there and a handful of other useful tools. Most of my test gear is USB based including the scope, VNA, Spectrum Analyzer and Signal Generator, that way I only have one screen to watch rather than four. I have however splurged on the soldering irons, I have two, one being a heavy duty device used for soldering to large lumps of metal.I realize that this is not a workshop/lab that everyone will like or approve of but it sure makes life easier. The last time I relocated from one country to another everything I owned fitted on one 1m x 1m x 1m pallet and it was an easy move.

But i can´t find this video.So here my questions1. i have 3 stripes with 6 leds on each stripe all 3 stripes were connected in series . i have only 1 info from connector Board :output 110 V dc so 110v DC /3stripes is about 36V per stripe or 6v per LED how much current is needed per Led?2. Is a Transformer with power output 36V DC 2A enough to drive all 3 stripes in paralell?3. Have i to build some cooling for the LEDs ?Sorry for my bad english !

content: If indeed it's 6V per LED, then it's likely 2 LED dies inside each package.You'll have to measure the current. There's no way of generalizing how much current they need. Single LED dies exist anywhere from typical 10mA for indicator LEDs all the way to ones using a few amps for lighting. And then they can be paralleled inside a single package.

content: Another thing is LEDs need to be driven off a constant current power supply, not constant voltage. Regulate the current to the required level, and the LEDs determine the voltage. If the LEDs have a forward voltage of 6V each and your supply voltage is 30V constant, then connect the LEDs in strings of in series, each with a suitable current limiting resistor. As mentioned above, you'll need to determine the operating current, to calculate the correct resistor value.

content: Ok, so i found something out3stripes in series each stripe has 6leds in series ->18 leds in serieso now the output from the powersupply has 117v 250mA so its a maximum of 29,5w divided by 18 leds gives me 1,625W 117V divided by 18 gives me 6,5v .so i have 6,5v with 1,625wso i can calculate I=P/U 1,625/6,5=0,25Aso i think i will make 6 packeges with 3 in Series in each packageso i can work with an older power supply wit an output of 19.2V.is this right?
OT:  Youtube and Patreon integration - Page 1

content: (I apologize if this is not permissible to ask such an off topic question. I will not object or even comment about this thread's deletion.)I have no direct experience, but many Youtube video makers tell of diminishing revenue from YouTube's partnership program. To fill the void, many Youtube content creators have Patreon accounts, which allow viewers to directly contribute to their favorite video makers. Sounds good, capitalism and all that.I was wondering how integrated Youtube and Patreon are.I'm not accusing Dave or any other content creator of doing or wanting to do this, but if a content maker only wanted to interact with those who donate via Patreon, is that an easy thing to do, or would it have to be done manually? That is, suppose "greatvids" made a video and "commenter" made a comment. Is there a way for "greatvids" to filter the comments and only see comments of those who have donated? (and thus make it easier to only respond to those who donate?) Or, would "greatvids" have to view a list of his or her donators and check each comment manually? "Oh, commenter donates via Patreon, so I'll answer him or her." "Othercommenter" did not, so he or she can buggar off."Time is limited, and I've heard several video makers say they spend a lot of time answering comments, so one would think some makers would only want to spend that time on people that donate - maximizing return on that time investment by making the donators feel better by interacting with them more than the "plebes" who don't donate.

Ie less people interested in youtube red or a potential paid videos option. You can see the same thing happened with twitch, people were using patreon/paypal to allow donations. Twitch wanted a cut of those donations, so they added it as a feature to their platform.

content: thm_w is correct, Patreon is completely separate from YouTube. All interaction with your patrons is usually done through the patreon website there is no integration with YouTube. You make posts on your Patreon and through that you interact with anyone who is donating to you, afaik you can even direct message and e-mail people through Patreon.

Most of those places charge about €200 no cure no pay, but I would rather pay 350 and actually get it fixed. The only issue with Rossmann is expensive international shipping and dealing with taxes.

The hard part was my lack of soldering skills in such a fine pitched connector. If you have a decent soldering setup, you should be able to tackle the job. Two things are critical though, the schematics (pdf) and boardview (.brd file), which can be found free on the web. You'll also need the the free openboardview software to view the .brd file. Note that you need a decent microscope to see what you're doing. I paid ~$700 for the microscope in order to make the repair (which was ~$1500 repair from Apple) but now I have a tool which I find is indispensable for smd work. Cheers.

Inductors and capacitors are on CPU package substrate, while all FETs, controller logic and gating is on the CPU die itself. On these CPUs input voltage is about 1.8V for this reason, as FIVR will downconvert this input to all internal voltages.

Vicor's solution pretty much eliminates all the VRM next to the core. Not to mention, maybe a few hundred pins (as far as I recall, a modern cpu has some 500-ish power pins). Or maybe modern FPGA-s could be designed in without "PHD in power electronics", or just throwing money at the problem.

The latter can not be read by conventional image software. For more information on how it was scanned, see NSSDC link below.To get the RAW files, see 'Download options' window and click on 'SHOW ALL'Why, and story:The Apollo 16 UVC experiment photos are not all readily available on the internet. Original files have been received by NASA by asking here:http://nssdc.gsfc.nasa.gov/nmc/datasetDisplay.do?id=ASUV-00017We received the images.... and what we got were completely non-standardfiles not readable by any image software. They appear to be raw bitstreams taken from the tape. Luckily, information on how they werescanned and saved is available. But it still posed a challenge.After writing a decoder for the files we received from NASA, we slowly but surely began to get recognizable images.We continued to tweak the decoder, until we finally got acceptable results that looked like the few images online by NASA. We have converted them all to JPG and uploaded here.Usefull Information:The Revised S201 catalog of far-ultraviolet objects inspects some images in detail. A great source of information.https://babel.hathitrust.org/cgi/pt?id=mdp.Later additions to archive:I have added several S201 catalogs in PDF and txt format.I have also added scans of other documents and papers, some of which were used at Houston.I found a book about Apollo that has an AS16-123 frame, I photographed the book and uploaded the file as: ApolloDossiervanhetProject#.pngRead: DocumentINFORMATION.txt for more info.Bonus slideshow:

Of course, they will blame "flooding in our factory", or earthquake or some other bullshit. And keep the prices up artificially by limiting the production values.This one is a hostage of the interface. Writing speed is 10MB/sec, so it takes 11 hours to write it full.
