My first Brighthouse/ Road Runner Rant after 12 years - Page 1

content: I know complaining isn't going to get anywhere but sometimes just simply venting is enough. I have been a Brighthouse customer for 12 years. For those who don't know, they are a large regional cable company who consistantly ranks high in JD Power surveys, for what it's worth.After being on vacation for awhile and not checking email after that, I finally check my road runner email and I get an error that the incoming mail server is not responding. I triple check all the settings in outlook 2007, send a test message which completes successfully but I don't see it in my inbox. I check webmail and it's there.Now to get on the phone. I finally get through and ask if there is anything wrong with my email account or has anything changed. The CSR gives no indication that anything has changed or is wrong. She has me try a few things w/o success. Then she has me change the port assignments for the incoming mail server. I ask when did this happen. She said it was always the ports she gave me. My reply was that was incorrect as my email has worked for 12 years up until 2 weeks ago. She has me test and still no love. Then she tells me to change in incoming and outgoing mail server names to something different. All of a sudden, mail starts downloading. I ask, did this change within the last 2 weeks as that was the last time I got email. Now, her response is yes. I asked why didn't Brighthouse send out a notice to all its customers that this was happening. I got no real answer as I guess that the question wasn't in her script book.Brighthouse has a large customer base. It is my only option as I am too far from the CO to get DSL service. Their service has always been great, the Internet down time percentage is almost non existent and I have received messages from them in the past when there was a planned service interruption. I don't understand why they couldn't be arsed to send a notification out that the changes were taking place so myself and other customers could have made the appropriate changes in a timely manner instead of wasting time calling tech support. It would have not taken much on their part and I could have saved over a half hour including hold time and simply made the changes in about a minute.Brighthouse is now Spectrum as they and other cable companies have been bought up. Hopefully this is something that just slipped through the cracks during the transition and not the start of a trend. Anyway, as I said, just a vent because venting to SWMBO is a waste of time, she uses only a single gmail account, where I have 7 different email accounts including 2 roadrunner. She could care less, unless the Internet is down and then the world is spinning off its axis into the sun and I need to fix it right the hell now.

content: Hello, just wanted to voice my admiration for Dave as an outstanding youtube personality. This guy is something special. The energy and enthusiasm he puts into everything he shares with the youniverse never fails to astonish me. His family also deserves praise as the volume of video content must consume a great amount of personal time.For those who agree fame is its own reward and a sycophant is about the most annoying and repulsive individual alive, as low and repugnant as a spy or sheep thief, I say Dave isn't all that attractive as far as youtube entertainers go, his garage shop wit is often soggy, and some of his math is as relevant as an expiration date on a package of dental floss.

All the many years I have spent playing with old military, scientific, and industrial gear I cant say that I have ever seen one of those. If you could have shown them a modern plated through solder masked FR-4 board they would have had their minds blown. It is so much easier and was well within their abilities of the time. They just did not put the ideas together until a few decades later.

content: It seams that Wattway is almost herehttps://ing.dk/artikel/frankrig-bygger-foerste-solcellevej-189140After nearly five years of research, the French engineering firm Colas now ready to perform 100 test roads worldwide with their Wattway solar panels.By combining several types of plastic, and a rough surface of broken glass, it has been possible to encapsulate Colas a conventional solar panel in a clear housing that can withstand both the climate and the weight differences from the trucks.The panels in Wattway systems measure only 7 mm in height Photo: ColasThe new solcellevej is only 7 millimeters high and, according to Colas laid directly onto existing surfaces such as asphalt, concrete and tile. In addition to making the panels slip, the broken glass surface also make panels resistant to wear.The first stretch of road on 2,800 square meters is under construction in the French village of Tourouvre in Normandy. The line is expected to generate 280 kilowatts at an optimal day, which according to Colas is enough to power a town of 5,000 inhabitants with street lighting an entire year.Three lines in DenmarkTo test the new solbelægning in all weather conditions plan Colas additional 100 test roads worldwide."We have to test under all kinds of traffic and climate. However, we are concerned that the panels can cope with a snowplow, says Colas' technical director, Philippe Harelle.Colas Danish section rates in this context to be able to behave 2:00 to 3:00 solar cell lines in Denmark as early as next year."We are working to get two to three sample stretches out in 2017, if we can get some municipalities," says product engineering manager at Colas Denmark Lars Ladehoff.The price of Wattway panels are not at the cheap end. So far, costing the panels between 15,000 and 19,000 kr. Per. square meters. This price include also the installation of the panels.

content: To understand Bitcoin you need to grok two concepts - a digital signature and a hash function.If that is not your cup of tea, then you would have to make do with analogies.A bitcoin address is the public part of a "public key cryptography" type key pair.One who holds the private key can spend the coins.One who is told the public key (address) can send coins to that key from one of his own.This is typically abstracted into a wallet - software that automatically handles all your private keys and gives you a balance readout.To pay, you need to use that software to send coins to an address the seller gave you.To get paid, you need to provide an address (the wallet software would make one for you) to whomever would pay you.There are many places that can exchange fiat money to and from Bitcoin, as well as payment processors that would take, say, PayPal and pay to a bitcoin address that you need.At the time, one Bitcoin (BTC) is worth about US$730, but that tend to vary a bit.Really, you should start with the FAQ and lists of things athttps://bitcoin.org/en/and read about it.If you have any specific questions, do ask.

It's actually pretty crazy, our temp range (In F, way better for measuring weather) can go from -10 to 100, with it being a bit warmer down in New Britain.

content: In general, the Ah capacity of batteries sold from China are not worth the plastic they are printed on. The vendors/manufacturers lie so they can get you to click on buying theirs over some other fraudster's batteries.Best to buy genuine Sanyo Eneloop or genuine Panasonics. Problem is the Chinese are so good at pirating the genuine article you cannot tell the difference from the outside. This is particularly the case with mobile and cordless phone replacement batteries. There are many "Genuine" Samsung batteries (complete with barcode or hologram) that are just fakes, imported from China and sold locally via eBay. If you want to eliminate the risk, buy from a reputable dealer in your country, not from eBay.Most of the torches sold on eBay from China are also rubbish. They don't last very long. Best to pay more for a reputable brand from a reputable retailer.Years ago retail stores sold boom boxes (AM/FM cassette stereos you carted on your shoulder) that boasted "20,000 mW of Peak Power!". One I saw stated something like "1,000,000 uW power output" on a cheap no-name cassette stereo! They were marketing to the ignorant masses. The manufacturers did not lie, just exploited non-technical people by making the numbers look good. With the 9900 mAh batteries they not only marketing to the ignorant masses, they are straight out lying.In the end you get what you pay for.

Probe tip is quite long at 14.5cm.See Attached picture 1.Bits in the bag are from a previous surgical examination of a Minelab Pro Find 25. (lower circuit board & copper coil)See attached picture 2.As you can see the end is a tiny thin wire coil. No ferrite rod even, so it actually does pretty well (10cm range)It was surprisingly easy to remove the innards, they were not sealed in with resin as I was expecting (apart from end), only some rubber. Although the whole detector was a glued pvc pipe, with an expanded rubber seal where battery went in. After opening the end up, I actually noticed some sand grains inside of the rubber seal, which makes me think that water could actually get in a way. Very concerning as I had not used it at depth, and with all that air within would increase the pressures if it was taken far down.Suppose the tiny coil made it very power efficient, I've not replaced the battery yet.What is the purpose of destroying $300 metal detecting pointers?The first pointer is to improve the design.The second pointer is to try and fix the 1minute off timer. But since it seems to be completely poos. I guess I'll try to do that, maybe, but repackage it in a tinier size and resell.

content: Yes, the "tiny" thin wire coil was stuck right up against the end cap with a large amount of resin behind it.Pointer has a very long end, and they had a very long wire from pcb to that coil, bit weird - doesn't seem efficient.It is designed for divers though, suppose they have to target deep rock cracks & silt. Also all that internal air space makes it a little boyant (perhaps that is not a desirable property to have).

content: Hi guys, I know this is a very general question, we need some UPC/EAN codes to sell online (ag Amazon) and I am not sure how the system works. I can pay to buy say 100 codes, and they promise me they are unique and assigned only to me and valid for life. Or I can simply go to one of these "make your own UPC" websites and make a code. However I think that if I make up my own code it will not be unique and will likely be used by someone else somewhere else. So it pays to pay to buy the codes and thus guarantee uniqueness ? Am I understanding this right ?

rigol ds1052e knob trouble - Page 1

content: I'm new to this forum and I hope I'm in the right place...I'm facing problems with a rigol ds1052e dso. the hw version is 58, i've bought it from batronix in germany but i'm from italy and so it would be a problem to send it back for warranty repair. it is has a few months and about 30 power-ups. anyway the problem is that all knobs suddenly stopped working: the main knob (upper one) doesn't do anything; Vertical scale translates orizzontal trigger; while rotating vertical position it appears on the display the position osffset (as normal) but it flickers and stays the same; the same behavior has the trigger knob and horizontal position but this one "changes" the trigger; horizontal scale does nothing. all knobs when keeped pushed or some seconds display the right help and with his sotware the scope works fine, I mean it can be managed via virtual panel.I tried updating the firmware and changing it to 100MHz and it worked flawlessly but the knobs still not.this evening I will contact batronix but I wanted to have some other opinion, maybe someone who had the same problem before contacting them.

Voltage between Serial Rx & Gnd - Page 1

content: Hi GuysI have a pair of Commodore Amiga CD32 retro consoles, So that makes me cool right thereI noticed tonight making a serial cable (for receive only) to debug a microcontroller project,there is voltage between the serial Rx pin and Ground pin whether the serial port is open in software or not.The port does work as expected, but the Rx pin can light an LED quite well via a 470R current limiting resistor.Then I tried my other identical console and it was the same!Does anyone have an explanation for this? I have to have the pins correct because data is received on the Rx pin fine.The console can run the normal OS like other Amigas, and I use terminal software often for debugging micro projects.It’s a 5 Volt port, not RS232, or any negative levels. Transmit from the console is simply on & off.CheersEDIT,,, There’d be a better section for this, but I couldn’t delete it myself.Edit again,,,Maybe it should be moved to the beginner section.Hmm, why would you want to normally hold a pin high to stop it floating low and getting noise on it...

content: Yeah, made my own too. Works just fine with a reasonable DC fan. I have a small homebrew pwm controller to vary the speed as needed. Having the flexible 'hose' allows it to be moved where you need it easily and the louder fan noise in further away from you - though you do of course hear some noise.Some cheap activated carbon filter material that I cut from bulk material. Catches the large flux fumes. I have the fan/box behind the curtain and aim it out the window when the weather is 'warmer'. No fumes in my face.cheers,george.

content: My experience has been that it's more useful to blow air towards the work (ideally a "curtain" of air between you and the solder fumes, blowing across the table) rather than a suction arrangement. You can still add the extractor where the fan blows the fumes to, of course.

timestamp: November 19, 2016, 02:33:14 am
content: Don't know about blowing fumes all around you and over your work and anyone near you. Suction seems to work very well for the fumes I experience. I used a magnifier over the work area, so the fumes are pulled nicely into the large diameter ducting of my extraction system.It is very clear that the flux fumes (both hand soldering and solder paste on a hot plate) are being drawn into the ducting.Certainly with the flexible ducting I can place it above/behind/over the work I'm doing so can be adjusted to work well. I can imagine that the static bench fume unit would be problematic since they will rarely be where you need them.cheers,george.

I was thinking more about the typical "radio shack" model that is little more than a fan with some carbon foam in front of it, and those just have a far too large aperture to effectively suck in anything. I'll take a fan blowing the fumes away from me over those any day, preferably with an open window.

They do sell some of the past boxes individually, without subscription, but those are $60! Even using Amazon and picking only Prime eligible products I think you can obtain the same sets of components for much less - let alone going to ebay or elsewhere and ordering from China. For some it might be worth the extra cost for the convenience of not having to source components for a project. It would be nice to get something each month - heck my dogs get a box every month with goodies, I should too!

How to remove Sestic Contact Adhesive Cable Glue - Page 1

content: Hi All,I need to call on your combined expertise.A Customer had a very nice toilet sign made up (with Black Acrylic, and a transparent cutout).They wanted LED strips on the back of the sign.Normally I use the LED Strips that have the built on double sided tape, but I put a streak of Sestic Cable Glue as well, because the tape on the back of those strips is not too sticky.Now, I went and put a streak of this glue along the top part of the sign (the black acrylic), but I was distracted, or overtired from several nights overtime in a row, or whatever. And I did not realise that the sign was upside down.What that means is that the customers nice new laser cut expensive sign has a streak of this Contact Adhesive glue along the front, instead of the back.Is there a way to remove this adhesive, without melting the acrylic, or using a blade to shave the acrylic off?Thanks in advance for your insight.

content: The solvent in the Sestic dissolves the acrylic, so the only option, other than a new sign, is to gently scrape it all off ( Minora blade in a holder or a little masking tape to hold the other sharp edge) and repolish the sign. Brasso works well enough, though you will be buffing for ages, or look for some fine buffing compound from your local car painters, as they use a lot of it when respraying a car for some reason. I used to use some Acrylic polish, so give Maizey a call Monday and get some, it will take the top layer off and leave a nice shine.Been there, done that........
