An Herbalist Library: Historical References - Traditional Medicinals Our ancestors cultivated a deep, rooted relationship with plants; they harvested plants in ceremony, made herbal medicines with intention, and passed along traditional plant knowledge to help future generations maintain wellness. In many cultures this information was shared orally, through stories or an apprenticeship with a local healer. The books we do have on traditional herbal medicines are a treasure to modern day herbalists; they’re a window into our survival as a species and often hold surprising tidbits on how we once used common plants. Below, please find some of our favorite inspirational books from western herbalists that focus on traditional plant remedies, as well as the rich history of herbalism. A Modern Herbal, Volumes I & II by Sophia Emma Magdalene Grieve are some of the most well respected herbal books of the 20th century. If you’re looking for more books on herbalism, be sure to check out our first article in this series called An Herbalist Library.

Make a Shunt Resistor - Electric Circuit Make your own rough and ready shunt resistor home > electric circuit | education A shunt resistor (pictured above) is a high-precision resistor of very low resistance used by an ammeter to measure the current flowing through an electric circuit. Shunts are available in a range of sizes from under one Amp to many hundreds and thousands of Amps, but they can be very expensive. Fortunately it is possible to make your own shunt resistor from nothing more than a length of copper wire. Example DIY Shunt Resistor In this example we will look at making a 0-10 Amp shunt resistor with a voltage drop of 10mV at 10 Amps. So, what do we need the resistance of our shunt resistor to be for a 10mv voltage drop at 10 Amps? Resistance of Copper Wire Copper wire has a resistance which depends upon its length and its diameter.

5 Best Free and Open-source Real-time Strategy Games for Linux StarCraft and Red Alert are two of my favorite real-time strategy (RTS) games. Though these games are closed-source, they are still playable in Linux through Wine. Recently, I have tried a few free and open-source RTS games and was really impressed with some of them. The best thing is that I can play them instantly on my Linux box without the need for Wine and without having to spend a single dime. If you are into real-time strategy gaming, I highly recommend you check out these Free and Open-source RTS games: Warzone 2100Warzone 2100 was originally released in 1999 for Microsoft Windows and PlayStation. Although Warzone 2100 is comparable to Earth 2150 in many significant respects, it does contain certain unique aspects that clearly differentiate the two, including various radar technologies, a greater focus on artillery and counter-battery technology, more frequent in-game cinematic updates as gameplay progresses, and customizable vehicle designs.

No, you *CANNOT* run your 1800 Watt (hair dryer, blender, microwave, A/C) off a car battery. Here’s why: : vandwellers Tyndall Report | Year in Review 2015 ABC's NEW FORMAT (2015 vs 27-yr avg) NEXT YEAR's PRESIDENTIAL ELECTION… 2015 was a lackluster year. The top story was nothing more important than an unusually snowy winter. The economy set unnewsworthy records -- the least coverage of the last 28 years. The federal government attracted precious little attention too, despite successful negotiations to halt Iran's nuclear program. Paradoxically, ABC responded to this slow news year by revamping its format to emphasize breaking, often local, news. With the political mood energized both by Trump's nativism and by Black Lives Matter protests in Baltimore, this was the database's third-heaviest year for Race-&-Immigration, led by an influx of refugees in Europe, and racist murders in a Charleston church. The Most Newsworthy Man of the Year was Donald Trump, the would-be wall builder against Mexicans. TOP 20 MOST USED REPORTERS (Anchors excl)

All About Project Management Project management is a carefully planned and organized effort to accomplish a successful project. A project is a one-time effort that produces a specific result, for example, a building or a major new computer system. This is in contrast to a program, which is 1) an ongoing process, such as a quality control program, or 2) an activity to manage a series of multiple projects together. In some countries, the term "program" refers to a software tool and the term "programme" can mean a TV or radio show. Project management includes developing a project plan, which includes defining and confirming the project goals and objectives, identifying tasks and how goals will be achieved, quantifying the resources needed, and determining budgets and timelines for completion. Projects usually follow major phases or stages (with various titles for these), including feasibility, definition, project planning, implementation, evaluation and support/maintenance.

Battery School | Daily Amphere-Hour Consumption For Your RV Those RV-ers who prefer to stay in campgrounds with full hookups have different requirements than those who enjoy primitive camping without hookups. If you never boondock and always stay in places with electrical hookups, you probably can get by with one good quality deep-cycle battery. However, those RV-ers who sometimes or regularly depend on battery power for the house systems need to do some calculating in order to have enough batteries of the proper size to meet their requirements.The first step is to figure a typical day’s ampere-hour consumption. 6 Ways To Reduce Irrelevant Results On Google Search The internet doesn’t contain just a few dozen or hundred relevant sources, no, it contains millions or billions or even more. To make things worse, there is no friendly and intelligent librarian to help you sort through all this information. It’s only you and a stupid search engine. The challenge when searching online is to find only relevant information or – in other words – avoid irrelevant results on Google search. Surprisingly, the most effective way to reduce irrelevant results on Google search, may be not to use Google’s search engine in the first place. 1. Use multiple keywords to receive more specific results on your first search engine results page (SERP). 2. When you enter the first letters of a keyword into the search bar, Google will suggest popular keywords other people have used in their searches. 3. This is a whole article of its own and fortunately it has already been written. Use Quotes This is most commonly used to find an exact match. Search Within a Specific Website

$3 Wattmeter Those who browse the RCG threads are probably convinced as I am that #1 cause of motor/ESC failure is lack of wattmeter. Here's a solution that is so inexpensive there's no excuse anymore for not checking run current. Also good for seeing how much juice that charger's putting back in your battery or watching voltage creep up to the magic 3.8v/cell for storage. It is based on the Harbor Freight multimeter that is always on sale for $2.99 in at least one of the active catalogs. Switch to 20v to read volts and 10a to read amps (label says 10a but actually it reads up to 20a). update: It's good up to 20a using the regular banana plugs and no modifications to meter. Below is a pic of the bulb I used to calibrate. Remember, you need heavier connectors and wire to handle higher current. Like Curtis says you can add solder to the shunt between the wires to reduce readings for fine tuning. More update:
