Should You Use A Linear Or Switching Power Supply For Your Analog Synth?

byadmin

If you’re looking for a power supply for your analog synthesizer, you may be trying to decide between a linear power supply and a switching power supply. Whether you’re building your own analog synth, putting together a modular, or buying a power supply for a used vintage keyboard, you want to make sure that you don’t have to deal with any power issues. Obviously digital synths can utilize either a linear power supply or a switching power supply with no problems.

What’s the difference? A linear power supply uses large capacitors that are recharged at the frequency of the incoming AC power to store its energy. A switching power supply uses a switching regulator to convert electrical power, and unlike a linear power supply, it constantly switches between full-on and full-off states and minimizes wasted energy by spending very little time in the high dissipation transitions. Every computer uses a switching power supply, and many other high-power electronics also use them.

While many synth buffs would recommend using a linear power supply over a switching power supply for analog synths, especially modular synths, the conventional wisdom on this topic seems to not have kept up with changing technology. Today, many models of switching power supply offer smaller, cooler, and significantly more efficient power than linear power supplies. Even when used with modular synths, a switching power supply can offer efficient and surprisingly quiet operation. Many old-school modular enthusiasts, in particular, argue against the use of linear power supplies for analog synths due to their perceived added noise, but a modern switching power supply is often just as quiet as a linear one. While they aren’t perfect for every application, there are many cases where a switching power supply is perfect for the job.

Tempted to build your own power supply? While many owners of modular synths see it as a more economical solution, a homemade power supply will lack the stability and safety of a good switching power supply. Think of all the modules in your rack. An errant surge or an internal power failure in a homemade power supply could easily destroy all of your synth modules. Don’ take that risk. Use a good switching power supply, and you won’t have to worry about that occurring.

If you’re looking for a power supply for your analog synth, there’s no reason not to choose a switching power supply. Despite the objections of many older synth enthusiasts, today a high-quality switching power supply can provide the same quiet power to your analog synths that a linear power supply can. Ignore the conventional wisdom that a switching power supply should never be used with an analog synth, and you’ll enjoy more efficiency with a switching power supply.

United States Senate prepares for floor vote on net neutrality

United States Senate prepares for floor vote on net neutrality

{{tasks|news|re-review}}Tuesday, January 9, 2018

On Monday, Democrats in the United States Senate announced they had gained enough sponsors to perform a congressional review of the Federal Communications Commission (FCC)’s December 2017 reversal of previous rules regulating Internet service providers, commonly called Net Neutrality.

Under the Congressional Review Act, if 30 senators co-sponsor the action, United States Congress can vote on whether to overrule a decision made by a federal agency such as the FCC. Both the House of Representatives and the Senate would have vote in favor, and President Donald Trump would have to sign the review.

On Monday, Claire McCaskill of Missouri announced she was the 30th senator to agree to sponsor the floor vote. “What I’ve heard from the thousands of Missourians who’ve contacted my office is simple — consumers should have protected, free, and open access to the online content of their choosing,” she said in a statement.

The Obama-era Net Neutrality rules were revoked last month. On December 14, as protesters gathered in Washington D.C., the United States Federal Communications Commission under Chairman Ajit Pai voted 3-2 to overturn the 2015 decision, which forbade Internet service providers (ISPs) such as Verizon, Comcast, and AT&T from blocking individual websites or charging websites or customers more for faster load times.

Specifically, the 2015 decision placed the Internet under Title II of the 1934 Telecommunications Act, which established that Internet access must be regulated under the same rules as a utility. Currently, in the U.S., telephones are regulated in this way, but cable television is not. Cable providers can offer bundled services and otherwise select which channels to offer customers; they do not have to offer access to every channel the way ISPs have offered access to the whole Internet. The new rules voted on December 14 transfer the Internet from the jurisdiction of the Federal Communications Commission to the Federal Trade Commission, which means instead of being forbidden from blocking websites or offering different access speeds, ISPs will only be required to disclose having done so.

Telecom analyst Gigi Sohn, who worked with Pai’s predecessor Tom Wheeler in 2015, said, “There are going to be fast lanes and slow lanes[…] As a consumer, that means some of your favorite websites are going to load more slowly, and it also may mean some of your favorite content goes away because the provider just can’t pay the fee.”

Former Etsy CEO Chad Dickerson said, “Net neutrality allowed something like Etsy to hang out a shingle on the web and give it a try”.

Supporters of the new rule argue Net Neutrality regulations were unnecessary. Commissioner Michael O’Reilly pointed out the Internet “has functioned without net neutrality rules for far longer than it has without [sic] them.”

“Quite simply, we are restoring the light-touch framework that has governed the internet for most of its existence,” said Chairman Pai, who argued removing the rules would make the Internet freer and more open.

“[T]he internet will continue to work tomorrow just as it always has,” promised AT&T Senior Executive Vice President Bob Quinn, who said his company would not block websites or discriminate with respect to content.

Opposition was organized almost immediately and was not limited to plans for congressional review: The Attorneys General for the states of New York and Washington have both announced plans for lawsuits against the new rules.. The United States Congress also has the authority to overrule the FCC’s decision by passing legislation. One such bill, House Resolution 4585, or the “Save Net Neutrality Act of 2017,” was introduced to the U.S. House of Representatives on December 7.

According to a poll conducted the week of December 6 by the University of Maryland, more than 80% of registered U.S. voters opposed the repeal of Net Neutrality, 75% of registered Republicans, 89% of registered Democrats, and 86% of independents, those not registered to either party. Before the vote, the FCC had accepted comments on the measure from the public through its website, FCC.gov. However, there have been allegations that many of the comments offered in support of the rollback were fakes. Before the vote took place, attorneys general from seventeen states and the District of Columbia sent a letter to the FCC asking the vote be delayed until the matter could be investigated.

The FCC’s decision must be published in the U.S. Federal Register before congressional review can take place or any lawsuits filed.

Thousands evacuated after chemical truck overturns in Pennsylvania

Saturday, March 21, 2009

A tractor-trailer carrying 32,000 pounds of hydrofluoric acid overturned on a northeastern Pennsylvania highway early Saturday morning, prompting the evacuation of about 5,000 people. The truck, registered to the Honeywell company, flipped over at about 2:40 a.m. after the driver swerved to avoid a deer.

The pressurized acid began to leak after the vehicle flipped over onto its side on Route 33 in Plainfield Township, but Northampton County authorities said Saturday the nobody was injured and the leak was contained by noon.

Residents were evacuated as Hazmat officials were brought in to clean up the site. Inhalation of hydrofluoric acid can be fatal, and low doses can irritate the eyes, nose and respiratory tract.

But Northampton County Administration Director John Conklin said the leak was slow-moving, and not enough of the chemical leaked to create a toxic cloud.

“This will be over real quick,” Conklin told CNN International.

Hundreds of evacuees were taken to the Pen Argyl Area High School in nearby Pen Argyl, but Conklin anticipated they would be able to return to their homes by the end of the day.

Hydrogen fluoride is a hazardous and highly corrosive chemical compound used mostly for industrial purposes. It is also an ingredient in high-octane gasoline, refrigerants and light bulbs.

The driver of the truck, Raymond Leblanc, 54, of Harrow, Ontario, was treated at Pocono Medical Center in East Stroudsburg for minor injuries and released Saturday. A passenger, Joseph Dault, 51, of Ontario, was not hurt.

Save Money By Maintaining Your Energy Efficient Appliances Valparaiso In

byAlma Abell

Thanks to the rising cost of energy production, people are truly becoming aware of the need for Energy Efficient Appliances Valparaiso IN. Unfortunately, it can be difficult to know what is hype and what makes an appliance truly efficient. Part of the problem is the differences between types of appliance. For example, a refrigerator consumes energy to keep the interior cold while an oven consumes its energy in the effort to heat its internal space. Both can be made more efficient with the application of insulation, but each appliance requires specific materials for that function. In this case a refrigerator may use polystyrene foam while the stove will use a fiberglass insulator.

For most people Energy Efficient Appliances Valparaiso IN are determined by the amount of energy they save. These numbers are usually displayed in a visible location in order to attract attention. However, they can be slightly misleading when compared to an existing appliance. Almost all the recent appliance designs from the last few decades incorporate some methods of energy efficiency. For the average consumer, the misunderstanding involves how much money they think they will save from using the new appliance. In most cases a new purchase isn’t much better than having an existing energy efficient appliance repaired.

Further improvements for supplying Energy Efficient Appliances Valparaiso IN would require technological changes in the way the appliance functions. For instance, a refrigerator or freezer operates by removing the heat from the enclosed space. They both use a technology that was developed in the early nineteen hundreds, the collection of heat via chemical absorption. As an appliance they represent the most efficient methods available for chilling storage areas. To improve this particular appliance would require a different method of heat removal or an improved method of condensing the current refrigerants.

There are things that can be done to ensure your energy efficient appliances remain that way. Appliance repair specialists like Anderson’s Appliance Repair Valparaiso IN recommend routine maintenance and regular cleaning to ensure your appliances operate the way they were designed to. Cleaning filters, coils or other sources of airflow can keep your appliances operating at low temperatures where required. This generally reduces the load on the appliance. Perhaps the best example of this is the dryer vent. When this outlet gets clogged, it forces the dryer to work harder to dry your clothes. The end result is more expense for the same work.

Original Story
  • “Hotel development proposal could displace Buffalo, NY business owners” — Wikinews, February 17, 2006

Friday, February 17, 2006

Buffalo, New York —Savarino Construction Services Corp. has proposed a $7 million hotel project at the Forest and Elmwood Avenue intersection, according to The Buffalo News. The proposal calls for a 5-story, 45,000 square-foot 80-room hotel with underground parking for at least 50 vehicles, and 4,500 square-feet of retail space on the lower level.

Hans Mobius, the owner of the five properties to be purchased in the plan (1109 to 1121 Elmwood), reportedly signed a contract with Savarino to assemble the development.

“We saw a huge opportunity to bring something to the Elmwood Village that will make sense and bring a service that’s currently not available,” said Eva Hassett, vice president of Savarino. “Elmwood is such a wonderful place to eat, shop, walk and spend time. We believe this project will add to that vibrant environment.”

Some business owners in the area see it differently. Wikinews interviewed 2 of the 4 owners whose business’s would be demolished if the development goes through.

Nancy Pollina, of Don Apparel at 1119 Elmwood, who found out about the development only yesterday, said she is “utterly” against the proposal. Her apparel shop has stood at the same location for nearly 14 years. She has volunteered in the community, and helped create several gardens around bus shelters in the city, and served on Forever Elmwood Board for six years as head of Beautification. Patty Morris co-owns Don Apparel with Pollina.

“To say this is a good looking project, I want to say the emperor has no clothes. This [project] does not take into consideration the needs of the college students. I have been told by college students, these shops here, are the reason they leave the campus,” said Mrs. Pollina.

Buffalo State College is 500-feet from the intersection.

Michael Faust, the owner of Mondo Video said, “Well, I do not really want to get kicked out of here. The landlord was very open, and the deal he made with me when I moved in here was ‘the rent is cheap and I [the landlord] will not fix anything and that will not change.'” Faust said he first learned of the development plan, “about 48 hours ago. I found out on Tuesday when the Buffalo News called and asked for my opinion on this.” Faust has not said if he will make plans to relocate. “We have to see if this [house] is going to get knocked down first,” said Faust.

An “informational” meeting, where citizens can voice opinions and learn about the proposal, will be held on Tuesday February 21, 2006 at 5:00pm (eastern), at the Burchfield-Penney Art Center Gallery at Buffalo State College, Rockwell Hall.

Executive director of Forever Elmwood Corporation, Justin P. Azzarella would not comment on whether or not the organization supports the development, saying, “you will just have to come to the meeting.”

Forever Elmwood Corp. is designed to preserve and protect the unique and historic nature of Elmwood Avenue and its surrounding neighborhoods and encourage neighborhood commercial revitalization. The organization was founded in 1994.

Nearly two years ago, the Forever Elmwood Corp. assisted in the blocking of the demolition of the Edward Atwater house at 1089 Elmwood next to Pano’s Restaurant which is at 1081 Elmwood. Owner Pano Georgiadis wanted to expand his restaurant onto the property where the house now stands, but the Common Council denied his permit to demolish saying the house is a historical landmark and needs to be protected. Georgiadis, who has a bleeding ulcer, said that all the court cases landed him in the hospital. “I got a bleeding ulcer, and since then, I don’t care about this house anymore, or this city. I just go to work every day. I think [preservationists] are parasites,” said Georgiadis.

Georgiadis will not be attending Tuesday’s meeting saying, “I will be out of town.”

In 1995 Hans Mobius proposed a plan to develop a Walgreens, that was to be placed in the same location, but residents and business owners shot down the proposal. Walgreens eventually withdrew its request for a variance after pressure from the community.

2008 AutoTronics Taipei: Participants from IT industry to participate COMPUTEX uncertainly

Friday, April 11, 2008

Since the AutoTronics Taipei was held from 2006, companies from electronic and automobile-related industries steadily made their stages and a good complementary in this trade show.

Before the first holding in 2006, because of the establishment of Car Electronics Pavilion in 2005 TAITRONICS Autumn (Taipei International Electronic Autumn Show), it (the pavilion) ever became a hot topic in these 2 industries. And eventually, Yulon Group recruited their sub-companies grouping their own pavilion to showcase automobile parts, accessories, and applications.

Currently, automobile navigation, mobile entertainment, and road safety, were included in modern automotive devices. But in a keynote speech of TARC Pavilion, Jamie Hsu (Consultant of Ministry of Economic Affairs of the Republic of the China) pointed out several threats and opportunities on the automotive industry, his words also echoed a notable quote by Yi-cheng Liu (Chairman of Taiwan Transportation Vehicle Manufacturers’ Association): “The automobile industry shouldn’t be monopolized by a company or its own industry. If this industry want to be grown up, it [the industry] should do more optimizations and transformations with the other related industries like IT and electronic.”

Although some participants like Renesas, Fujitsu, MiTAC, TomTom NV, and Agilent ever participated in Taipei IT Month, CeBIT, or Computex Taipei, but there were varied comments for participation on Computex 2008.

Computex 2008 will do a significant growth, of course. But we [Aglient] still consider to cooperate with Intel in a forum rather than showcasing in Computex.
We [the MiTAC Group] will appoint different sub-companies to participate in different trade shows by different industries. That’s why we showcase the same products in different shows by different sub-companies.

Renesas Technology, a participant of Computex 2007, won’t showcase in Computex 2008, but Fujitsu and TomTom both declared to participate in the 2008 Taipei IT Month.

Generally in the automobile industry, progressively conformed by the other industries, its success should depend on collaborations between different and similar industries because “not any company can do any monopoly in any industry” even though the automobile industry will become a “trillion industry” not only in Taiwan.
