I have seen plenty of electronics books being offered over the internet dating from the '70s and '80s. I would like to ask the veterans if something in the science of electronics had changed much in 40 years (besides the digital aspect, of course).

Hi guys, New here but not to projects and tinkering in general. Mostly im a mechanical type guy and not to electrically inclined. I have a 1970 Honda CT70H Trail bike, I would like to replace the current headlight with a single or multipul LED set, also id like to split it and run a USB charger when the headlight is not runnning. My plan to acomplish this (my very simple in a perfect world plan) is to take the LED set from a small cheap flashlight that uses 4 batteries in order to get the proper voltage, and use the same leads the go to the headlight. Currently the Honda has a dimmer switch which I was planning on using for my switch between light and usb power. For the usb I was going to use a car cig-lighter type charger and but i know a car is a 12 volt system however i assume because usb chargers use 5volts that a car charger has a 5volt regulator in place? Included is a ct70 wiring diagram link, help would be great http://ep.yimg.com/ca/I/dratv_2197_243290703 Thanks all

Arguably the original Heavy Metal band, Black Sabbath - Ozzy Osbourne (vocals and harmonica), Tony Iommi (guitars), Bill Ward (drums and vocals), and Geezer Butler (bass) - brought death, drugs, occultism, and all sort of things your Mother doesn't want you to know about to Rock 'n' Roll with 1970's self-titled album (released, appropriately enough, on Friday the Thirteenth). Following quickly on its' heels was Paranoid, then Master Of Reality (with the stoners' anthem, "Sweet Leaf"), and Vol. 4. For Sabbath Bloody Sabbath, they brought keyboardist Rick Wakeman onboard.. With controversial lyrics and song lengths that regularly ran to five and six minutes or more, you weren't likely to hear much of them on the local Pop radio station (shortened versions of "Iron Man" and "Paranoid" managed to get a bit of mainstream airplay in 1972), but they were a staple for Album-Oriented Rock stations and 8-track players everywhere during the '70s. Almost every song here is on my medium- or heavy-rotation list (four or five stars).. I bought the original CD reissues back in the early '80s and was impressed at how much better they sounded than the vinyl/tape I was used to - not great, but definitely better. A friend recently loaned me a set of 320k MP3s from the remastered CDs issued in 2004 by Sanctuary UK. I really wasn't expecting much from the early '70s recordings (and it _is_ Heavy Metal), but thought it would be a good excuse to sit down and have another listen. Was I ever in for a treat! The remastered recordings remove a lot of the "mud" from the recordings and really bring out the instruments, especially the drums - "Children Of The Grave" really benefits from the remastering. The title cut from the self-titled album sounds even more evil (count the number of bell tolls in the intro). Can't really say that the vocals sound any better (or worse, it's still Ozzy at his best) and, at times, there is still enough hiss to be distracting, but overall I was very impressed with the quality.. I'll call these discs a Must Buy for all Black Sabbath fans who have the vinyl, tape, or original CD issues - I'm shopping for my set. Any of the first four CDs would make a great introduction to their music for Heavy Metal fans (1972's "We Sold Our Soul For Rock 'n' Roll" is a 14-cut (two LPs, originally) Best-Of collection that has also been remastered and might be a better choice, even if it doesn't include "Rat Salad"). IMNSHO, Wakeman, although great with Yes and on his own, really detracted from the Black Sabbath sound, so I can't recommend Sabbath Bloody Sabbath for new listeners. -- nacho

Why do modern PCBs always use straight tracks and 45-degree diagonal tracks? I know it is good practice and design all my boards to this standard, but is there a reason behind it other than it looks visually appealing. It appears only relatively modern boards took this into account, I was looking at some 1970's electronics and quite a lot of them have rounded tracks of no definite thickness.

I had an old (about 1970s) large power transistor (I think it was a field-effect one, but I am not completely sure...). Knowing it is supposed to be light-sensitive I took the top of the case off, and it has a small EMF between the collector and emitter when exposed to light. But the EMF from directly under electroluminescent lamps in the school corridor is about 10 times smaller than from lying on a sun-lit windowsill. So light-intensity can't be the only thing the EMF depends on... But what is the other thing? PS It can't be UV, because well... we have glass in the windows at school, although it risks to get broken, as there is a football cup at the moment.

This video is about Nitinol memory metal engines that are basically Stirling heat engines and work on a very low temperature difference. I first say this material while watching a video on the founder of 'The Venus Project'. He had small spring that he would stretch out of shape and the heat it - it would come back to its original form and shape. I thought it was neat but didn't see the potential of the material. This video is from a 1970 CNN broadcast - when CNN was news instead of a propaganda machine. http://www.youtube.com/watch?v=7GfYlRakZ6Y The material is available on the web somewhere as others have purchased it since I showed them the video. At this point in time I am more of an information messenger and unable to partake in experimentation. So have at it guys and gals. God Bless

In the 1970's beer in the UK started turning bad. Fed-up the increasingly poor quality of beer that was too fizzy, had no character and no taste - some guys formed what was to become CAMRA.Largely due to CAMRA's efforts there are now a lot of independent breweries and several pubs selling their beers in my local area. I can get a good choice in several pubs in the town and village, last night I was at a small beer-festival - they had 63 beers on the list.This guy has a lot of information on the beer near me.In addition to 'real ale' a lot of these pubs have a wide range of bottled-beers such as European lagers. Then there are some bars that stick mainly to these imported beers.(You can drink fizzy tasteless stuff in plenty of bars of course)So what is the booze like where you are?

Once again I'm browsing coudal.com and I find something interesting. T'internet says: The Portsmouth Sinfonia was a real orchestra founded by a group of students at Portsmouth School of Art in Portsmouth, England, in 1970 — however, the Sinfonia had an unusual entrance requirement. Players had to be either non-musicians, or if a musician, play an instrument that was entirely new to them. Among the founding members was one of their teachers, English composer Gavin Bryars. The orchestra started as a one-off, tongue-in-cheek performance art ensemble but became a cultural phenomenon over the following ten years, with concerts, record albums, a film and a hit single. The impact of the Portsmouth Sinfonia was considerable and their name and reputation has endured even though they last performed publicly in 1979. But listen to 'em... And the rest. E.g. Dance of the Sugarplum Fairy And Satisfaction (Stones)

When I was a girl, in the 1970's, my Mom found a series of patterns for making Barbie clothes that didn't require sewing. Now I have several little girls around who want lots of Barbie clothes but they can't afford the prices. It would mean a lot to me if I could find these patterns to help them make their own clothes. As I recall there were dresses, pants, tops, etc. The clothing was tied on in various ways and the items were just cut out and ready for Barbie to wear. If you happen to know where I can find these patterns, please let me know as soon as possible. I would also be interested in really simple patterns for Barbie clothes. It needs to be something that a young girl can make with little or no adult assistance.

The Venera (Cyrillic: ÐÐµÐ½ÐµÑÐ°) series of probes were developed by the USSR between 1961 and 1984 to gather data from Venus. As with some of the USSR's other planetary probes, the later versions were launched in pairs with a second vehicle being launched soon after the first of the pair. Ten probes from the Venera series successfully landed on Venus and transmitted data from the surface, including the two Vega program and Venera-Halley probes. In addition, thirteen Venera probes successfully transmitted data from the atmosphere of Venus. Among the other results, probes of the series became the first man-made devices to enter the atmosphere of another planet (Venera 4 on October 18, 1967), to make a soft landing on another planet (Venera 7 on December 15, 1970), to return images from the planetary surface (Venera 9 on June 8, 1975), and to perform high-resolution radar mapping studies of Venus (Venera 15 on June 2, 1983). So, the entire series could be considered as highly successful. Unfortunately the surface conditions on Venus are extreme, which meant that the probes only survived on the surface for a duration of 23 minutes (initial probes) up to about two hours (final probes). Venera is the Russian name for Venus.

UK Broadcasting watchdog OfCom has ruled that the Channel 4 documentary The Great Global Warming Swindle broke broadcasting rules by implying that GW was not due to human activity.The film's key contentions were that the increase in atmospheric temperatures observed since the 1970s was not primarily caused by emissions of greenhouse gases from burning fossil fuels, and that the modern focus on climate change is based in politics rather than science. It is seen in some "climate sceptic" circles as a counter to Al Gore's movie An Inconvenient Truth, and credited with influencing public perception of climate science. It has reportedly been sold to 21 countries and distributed on DVD. GW experts featured in the documentary complained that they were quoted out of context, had not been told of the aims of the programme makers, and some quotes attributed to experts were, allegedly, made up by the reporters."It's very disappointing that Ofcom hasn't come up with a stronger statement about being misled," said Sir John Houghton, a former head of the UK Met Office and chair of the Intergovernmental Panel on Climate Change (IPCC) scientific assessment. "I know hundreds of people, literally hundreds, who were misled by it - they saw it, it was a well-produced programme and they imagined it had some truth behind it, so they were misled and it seems Ofcom didn't care about that," he told BBC News."The programme has been let off the hook on a highly questionable technicality," said Bob Ward, former head of media at the Royal Society, who played a prominent role in co-ordinating objections to the film. "The ruling noted that Channel 4 had admitted errors in the graphs and data used in the programme, yet decided that this did not cause harm or offence to the audience." Plaintiffs accused the programme of containing myriad factual inaccuracies, but Ofcom says it was "impractical and inappropriate for it to examine in detail all of the multifarious alleged examples... set out in the complaints." On another issue - whether contributors to the programme had been treated fairly - Ofcom mainly found against Channel 4 and the film's producer WagTV. Former UK chief scientific adviser Sir David King had been misquoted and had not been given a chance to put his case, the regulator said. Ofcom also found in favour of Carl Wunsch, an oceanographer interviewed for the programme, who said he had been invited to take part in a programme that would "discuss in a balanced way the complicated elements of understanding of climate change", but which turned out to be "an out-and-out propaganda piece, in which there is not even a gesture toward balance". The film alleged that the IPCC's scientific reports were driven by politics rather than science, and Ofcom ruled the organisation had not been given adequate time to respond.

We're used to thinking about the cost per unit of energy (e.g. $/gallon of gasoline) with the implicit assumption that cost is a rough indicator of what is required to obtain that energy. The Oil Drum has a nice piece on Energy Return on Investment (EROI) and the implications of using low EROI energy sources. To dive right in, it's instructive to think about the EROI of domestic oil production as a function of time:100:1 in 193030:1 in 197011-18:1 in 2000EROI on the Web part 2 of 5, (Provisional Results Summary, Imported Oil, Natural Gas)Energy return on investment, sometimes called EROI and sometimes called EROEI, is thought by many, including myself, to be a critical issue for determining the past, present and future status of human society. It is usually considered in terms of energy return on energy investment, but it can also be considered in terms of energy return on monetary investment. While much of human progress has been attributed, rightfully, to technology, much of that technology has been a means of using more energy for human ends. This is true for fire, knife blades and spear points (energy concentrating devices), the development of agriculture and the increase in its productivity and, essentially all aspects of the industrial revolution.EROI is simply the energy delivered by an energy-obtaining activity compared to the energy required to get it. If the numerator and denominator are expressed in the same units (barrels per barrel, MegaJoules per MegaJoule) the result is a dimensionless ratio, i.e. 100:1 or 10:1). Obviously a higher ratio implies a more desirable fuel than a lower one, other things being equal (which is rarely the case). The concept is extremely simple in theory but often very difficult in execution, mostly because society generally maintains its records in monetary rather than energy terms. Another problem is that the U.S. Government has not supported such studies in a consistent fashion and it is my perception that the quality of some energy records as are kept by e.g. the U.S. Departments of Energy and of Commerce appear to be deteriorating in recent years. Thus deriving the energy cost of getting energy (or most other things) is generally somewhat, and oftentimes exceedingly, difficult. A second problem is that the usual measure of the quantity of a fuel, its heat value, often does not give a full assessment of that fuel's ability to do economic or other work. Most simply electricity and thermal heat from e.g. coal or oil have a great difference in their ability to do work, such as we are willing to trade three or four heat units of coal or oil in a thermal plant for one thermal unit of higher quality electricity. Thus if the input and output fuels are of different quality then it is often thought desirable to weight in some way the inputs and the outputs. A third problem is that it is important to consider boundaries: how large should we draw the boundaries of the energy analysis for the inputs? We will consider these issues in far more detail in later publications but there are many reasons why it is important to make summaries of EROI available at this time even though many uncertainties exist in the numbers that we present here, and indeed with any numbers that might be possible to generate.via jforbess
