The Hidden Way to Zoom in Closer in Google Maps What Can You Do With A Slide Rule? Peter Alfeld, --- Department of Mathematics, --- College of Science --- University of Utah There was a time when electronic calculators did not yet exist. This did not stop us from doing complicated things, like going to the moon, figuring out the double helix, or designing the Boeing 747. In those days, when we needed to compute things, we used slide rules which are marvelous and beautiful instruments! There are many pages about slide rules on the web, and you can still buy brand new slide rules (40 years old but never used, and still in their factory supplied box) in various places. The purpose of this particular and quite idiosyncratic slide rule page is to describe common scales used on slide rules, and the kind of mathematical expressions that could be evaluated with those scales. The two images on this page show the two sides of a particular slide rule in my collection. German made slide rules of that time (the late 1960s) usually come with an accessory plastic ruler. Why? . .

Words, phrases, and acronyms that didn't exist 7 years ago are now used in an off-the-cuff style by developers and support technicians across the web. As the platform matures, this list of unique Android words continues to evolve, which makes it hard to stay on top of the latest terminology. But breaking things down into simple terms is what we do best here at Gadget Hacks, so below, we'll cover all of the latest Android lingo in layman's terms.

Slowing This page details the use of Epson^ InkJet printers with pigment based inks to feed and directly print resist patterns to copper clad printed circuit board stock, ready for etching. Once you can feed the PCB through the printer for etch resist, you can then feed it back through the printer for solder mask (yes! Several people report that it works quite well!) and for a component "silk-screen". Toner transfer is probably easier to set up for and may be as fast, but direct ink is more precise, allows solder mask and component printing in the appropriate color, and most importantly, finer traces and spaces! The secret (discovered by Volkan) is that certain pigment based inks, such as MISPRO Inks^ (#MISPRO42-SET-MK) can be cured with heat to form a very strong resist. Barry Cooper^ reports^ that Epson ultra chrome k3 ink in his Epson R2400 printer also resists etchant if fully cured. Printer Modifications: "I am currently using 1/16" [PCB stock].

Les entourages metro Paris d'Hector Guimard vs Neri 21 avril 2016 Lors de la création des premières lignes du métro, un concours pour la réalisation d’édicules d’accès aux stations est lancé en 1899 par la Compagnie du chemin de fer métropolitain de Paris (CMP). Ceux-ci doivent être vitrés « sur la plus grande hauteur possible, à partir de un mètre environ du sol ». Ils doivent également être « ornés d’une frise pouvant recevoir des caractères très apparents, éclairés par transparence pendant la nuit, portant l’indication : Chemin de fer métropolitain ». C’est le président de la CMP, Adrien Bénard, qui propose un architecte de l’Art nouveau : Hector Guimard. Dès 1904, pour l’accès aux grandes stations situées devant des monuments comme l’Opéra ou la Madeleine, la CMP fait réaliser des entourages plus classiques en pierre de taille par l’architecte Cassien-Bernard.

600 Social Media Network Sites on one page 600 Social Media Network Sites on one page A social networking service or social media network is a platform to build social networks or social relations among people who share interests, activities, backgrounds or real-life connections. A social network service consists of a representation of each user (often a profile), his social links, and a variety of additional services. Social networks are web-based services that allow individuals to create a public profile, to create a list of users with whom to share connections, and view and cross the connections within the system. Top 15 Most Popular Social Networking Sites (sep 2014) Here are the top 15 Most Popular Social Networking Sites as derived from our eBizMBA Rank which is a continually updated average of each website’s Alexa Global Traffic Rank, and U.S. And here is the rest!

Electronics Tech Tips When working with SMT components, a solder-paste silk screen method plus a good baking in a special oven to make the paste flow works best. But for most of us working on small projects with a limited budget, angel hair solder and a fine tip iron that is ESD safely grounded is the way to go. Those new to SMD components may struggle with "tomb stoning," which happens when one end of the component is soldered and the other end pops up in the air. Here's an easy solution. You will need to use both hands (assuming they do not shake too much) one to hold the Iron and solder and the other to hold down the passive component with a small tool or tooth pick until the iron is removed and the solder has solidified. Bruce Weidner Columbus, Ohio Alternative PCB Etchant I thought I would share my experiences with creating quality circuit boards using household supplies as an etchant. I set out to create an etchant that, by my calculation, would be roughly 8 times cheaper than ferric chloride. Supplies:
