content: Thunderfoot did a video on it but as usual he was full of arrogance and mixed up heat of boiling with heat of vaporization of water, so his video needs its own debunking.I'm looking for this device to send dave that emits a signal through the mains wiring in your house to scare away pests. Havent been able to find it to send it him, plus I'm in the states so takes a while to send down under.Can we put together a list then send patreon money so dave can buy it?

But if it does emit something, then how can you easily debunk that?Some large scale controlled test with hundreds of coachroaches?

content: Mains wiring thing does sweet FA, and the ultrasonic just annoys the cats, and might do the same for rodents, but otherwise no real difference in the cockroach problem. Blue wax got rid of the rodents ( using a Tomcat trap), borax got the roaches very dead, and now no problems. The cat is happy as well, just looks out the window and thinks of birds.

As someone with 'The Knack' and Aspergers I can appreciate that video but we also need to think of the poor souls who suffer from the reverse condition. You know who I mean, the sort of people who walk into a room and the clock stops, they pick up a piece of equipment and the power button falls off.My father was one of these people. One day my mother was listening to a record and a friend came to the door, she asked my father to take the record off and, after standing in front of the HiFi for a minute or so, he just unplugged it at the mains.

content: Hi all-There used to be a small hand-held device that allowed you to see the magnetic modulation patterns recorded onto magnetic tape. It looked a bit like a jewelers loupe - small, passive, handheld. I would guess it consisted of something not too far removed from iron filings suspended in mineral oil.Does anyone remember what this thing was called? It was fairly common back in the days of razor blade editing... (did I just date myself? LOL).

content: Off topic but was watching a series called Mayday (plane crashes). One episode they had a black box that was so badly damaged the only way to analyze the data on the damaged tape was using a technology, I think called Granette ?? , where the 1' and 0's on the tape had to be viewed under a microscope with a special lens. They had to construct the bytes of data bit by bit through the microscope, would take days to recover 1 second of data. Couldn't imagine a more boring job.

It would have been an excellent shoe to sell at a podiatrist shop (you know - the ones that sell strange German insoles for $100 or more - or weird shoes - or Birkenstocks). This is assuming it has palpable advantages over Velcro and slip-ons - perhaps in running or exercising.But given it is on Nike's menu - it will lose out in the ability of a mass marketer to have a niche line that makes a piddling. Perhaps a good shoe with decent market potential but made by the wrong company.CEO's cut these types of products as an act of "refocusing" - unless they are able to make a lasting marketing impression (which would require Phil Knight to parachute a decision to continue making the shoe).

content: I have been designing and supporting production products long enough to be used to dealing with EOL situations weather its BOM or board or new product. Recently I have had an entirely new experience with an EOL'd part.After sending order for a new batch I get word from our CM that one of the arts on the BOM has been EOL'd (a SOT-23-6 synchronous buck regulator, in case you were wondering), but our vendors have suggested drop in replacement xxy for the xxx part. Seems legit as a replacement only one digit n the pn has been incremented. I look up the various supplier links and yep they all say the same thing. OK lets go ahead with the part.On to some du-diligence before the boards are stuffed, I order some samples to test on a board. Hmmm, no workie, in a blow the input fuse kind of way. Hmmmmm, datasheet, yesss. Looks for datasheet on DK, nope not here, ok the other big 2 suppliers, nope. Move on to the manufacturers website. There's the old part, part page; all marked with warnings not to use. Where's the new part page? Its nowhere to be found, let alone any mention of the part on the manufacturers website. Fiiiine, I'll submit a tech request on the website. Might as well have gone and sat by a lake.I am not going to mention the half transistor company yet as I have not fully given up on the situation.This is pretty bothersome though, how can a major company be selling parts and not make any information available, or even be unresponsive to requests. I don't even need an FAE, just someone capable of emailing a frickin datasheet. This is enough of a move to almost discourage me entirely from using any of the companies parts, no matter how generic they may be.

content: So, I decided to watch David Blaine's new movie where he performs his magic to a bunch of famous people. He comes up with some physically impossible tricks, stuff that could never happen in the real world. As a good skeptic I was trying to figure out how he was doing most of his tricks but as expected, couldn't identify any of them. Is there anyone here into "magic" (I know magic does not exist)? I wish James Randi was still in his prime to come up with some explanation for his most intriguing stunts.

content: A Heat-Driven Transistor.Researchers at Linköping University, Sweden, have reported what they say is the first demonstration of a low-voltage, heat-gated organic transistor, a device that converts modulations in temperature gradient to modulations in electric drain current (Nat. Commun., doi: 10.1038/ncomms14214). The team believes that the device—the temperature-sensing amplification of which is, according to the study, “thousands of times superior to that of a single thermoelectric leg in traditional thermopiles”—could have “important applications” in the realm of infrared photonic devices, including smart temperature sensors, inexpensive thermal cameras and improved heat-sensing electronic skins.http://www.osa-opn.org/home/newsroom/2017/february/a_heat-driven_transistor/

Advice on choosing a lawn (grass) variety [AU] [Totally off topic] - Page 1
Forum section: electronics / general

author: Halcyon
author_rank: Unknown
timestamp: February 18, 2017, 08:21:51 am
content: Forgive me for the off-topic post (I figured we have people of many talents here). I've done months of Googling and have come up with a short-list of grasses I want for my front and rear lawn. However I don't really have much of a "green thumb" so I only know the very basics.Basically, I live in a reletively "cool climate" region of New South Wales (AU) where the average temperature in Summer rarely gets above 28°C and the average low in Winter is around 7°C. We do get frost over night in winter with the occasional light snowfall.Drought isn't too much of an issue, we average about 1000mm of rain in a year but I have a huge supply of water from a water tank so I can water the lawn at any time, even during "drought" periods.I'm seriously considering the "Kentucky Bluegrass" as it has a lovely blue tint (shown below).Does anyone have any thoughts? Do you have a lawn that you love/hate and why? What would you do different?Keep in mind, I plan to grow it from seed, not turf as it would be prohibitively expensive to cover the area that I need. My only other requirement is that it be fairly low-maintenance (mowing isn't an issue but I don't want to have to constantly be de-thatching, weeding or fertilising). It won't be subject to much foot traffic either.

Mixtures including bluegrass and fescues are common in parts of the US where it rains that much (and if you don't care about it being perfect, almost maintenance-free). Admittedly, those parts of the US are really only particularly dry in the winter when the plant goes dormant. >2 weeks at summer temperatures with no rain and it will certainly need water though.Even the more drought-tolerant fescues do not survive without irrigation where I live in California where there are basically 4 months of no rain.
STORY: The Levitating Timepiece - Page 1

timestamp: February 17, 2017, 09:39:05 pm
content: Hi All,Here is a Kickstarter campaign for a clock which shows the time by levitating a "bearing ball":https://www.kickstarter.com/projects/flyte/story-the-levitating-timepieceImage video:https://youtu.be/VQ_E81_hJjUThe only question is how this thing works?I guess the most simple solution would be a mechanical arm plus some magnets driven by a continuous servo or stepper, but the noise would be unpleasant.Probably they use a set of coils for positioning the ball on a specific point of the arc and permanent magnets for holding it. From this the ball also should be magnetized.The permanent magnets could attract the ball and the coils repel them, so if there is power outage, the ball does not land on the floor.It seems that the thing requires a massive amount of power (no battery option?) to keep the ball levitating, since the power cable leading to the clock's body is ruining the illusion that some magic is happening...Ákos

content: Well I would guess the ball itself is a thin shell spun copper ball, so it is light mass, and easier to position. Might have a small neodynium magnet in the one end to help with the levitation, and then there is a levitation structure under the surface ( likely with some slip rings for power and control signals) that is driven by a stepper motor to move the ball on the surface, using a standard feedback loop to keep it levitated.Not sure if the demos are done with the unit on a wall or face down on a table, but doable, and the display is easy enough to do with a series of LED dots under a thin wood veneer, common these days in clocks that have invisible digits. the side lighting I would guess is WS series programmable led units along the clock underside that light up according to the microcontroller programming, and I see it has both wifi and likely is IOT as well to get current time.

You can probably find similar "regular voltage" version and it will be less expansive.I found Cementex kit in a pawn shop. Mine are also high voltage version. The screw drives in mine are probably Kline Tools, but there is no marks that I can see or they are covered by the protective high voltage coating. Some of the tools in the kit are marked with Channellock logo so clearly Cementex buys tools from others, applies their high voltage protective coating and sells them under their brand name.
