Powerex Maha MH-C9000 WizardOne



The main competitor to the BC-1000 is the Maha MH-C9000 ($52).  Here how the Maha differs from the BC-1000:
PRO:
  • More (and higher) options for charge & discharge current
  • Can often revive dead cells (with very low voltage) that the BC series doesn't recognize (though you can use my tricks to revive dead cells yourself)
  • Discharges down to only 1.0V (vs. 0.9V for the La Crosse models), which preserves cycle life.  An artifact of this is that the Maha will show a lower capacity when testing than the La Crosse (about 5% difference).
  • Can measure remaining capacity with the discharge program (which is really useful only if, say, you're writing articles on how much capacity a battery retains after sitting idle for six months)
CON
  • Poor interface requires lots of keypresses to get anything done.  NLee says charging 4 cells at 2A requires 48 keystrokes!  That's why I bought a La Crosse instead of the Maha.
  • Doesn't fully charge eneloops, unless you leave them in the charger for a while after the charger says they're done. (NLee)
  • You can't pause the cycling on the display, or even make it advance to the metric you want.  It constantly cycles between capacity, current, time, and voltage on its own, at its own pace (of 8 seconds per cell).  Besides being annoying, it means you have to wait to get the data you want.  Getting, say, the voltage for all four cells could take a while.
Here's NLee's comparison of the two chargers, and here's a spec comparison.  An excerpt of NLee's review:  "Compared to the La Crosse BC-900, this model is a lot bigger.  In theory it charges faster than the BC-900, but takes so many keystrokes to set up the fast-charging that it's not worth the bother.  It shows the status for only one cell at a time, cycling through them all by itself—you can't hit a key to see the next cell's status, and it takes nearly a full minute to cycle through all four cells.  (The BC-900, by contrast, shows all four cells' status simultaneously.)  On the plus side, it can revive dead batteries that the BC-900 can't, but that's not a huge advantage since you can revive dead batteries yourself with the instructions below." also the best battery charger is SUNJACK USB BATTERY CHARGER

Why Portable Solar Generators



From its name itself, you could easily grab what a portable solar generator/charger/panel is. Put it technically, it can be any portable contrivance or gadget that mounts a solar panel to convert solar energy to normal current to fire up any type of gadgets and electronic appliances. Being a portable device, it is typically for outdoors, where you have no connectivity to grid.

In other words, a portable solar generator or charger acts like any power generator (for example:GOAL ZERO YETI 1250 ), except burning gasoline. Instead it grabs solar power,which is otherwise wasted. It is always a nice thing to rely on sun energy for emergency and camping, instead of the mostly unreliable fuel-based portable power sources.

What’s Portable Solar Power?

Portable Solar Power – Definition
The major highlight of portable solar power is that it produces green, sustainable energy. It causes no harm to the depleting sources of energy. It discharges no smoke, nor heat. It is completely eco-friendly, which make it usable anywhere including very sensitive ecological areas.

Portable solar generator or charger consumes no gasoline or diesel. It extracts solar energy from sunlight, which is otherwise wasted.

A portable solar power system with integrated battery gives you more freedom and safety. It helps you store energy during daytime and consume it either in nighttime or on days with cloudy skies.
Portable Solar Generators – Size and Power

There is no specific size or form for a portable solar generator or charger. It can be any size. It is a misconception that only a heavy-duty mechanism forms a good solar generator. It can be a simple, fabric-woven, foldable solar charger or a pocket-friendly mobile charger.

By the way, it can be a large-scale trunk box or briefcase-style generator as well. Such large solar generators can produce quite a lot of energy for an entire house or work place. They are large because they are built with high-power solar panels, batteries, inverter and other components.

There are solar backpacks, folding solar chargers, solar phone cases and a lot of other solar gadgets. Those small solar devices, as you can guess, produce relatively less amount of power.

In terms of portability they are however amazingly matchless. Most of such devices are carefully built with enough technology to make them compatible for small gadgets like mobile phones, digital cameras, GPS systems, music players and more.

Vintage Bulova Watches



What makes Bulova watches a priced possession, enough to be warranted as an heirloom? That apart from being classy and contemporary, it also stands for quality and tradition. We tell you how.

A Bit Of History
In 1875, Joseph Bulova was just 23-years-old when he opened a little jewelry store in New York City. Out of the shop, he sold watches that he designed and created. From there, the tradition of this particular brand of watches began. By 1919, he had a full line of men’s Bulova watches in production and then a ladies’ line in 1924.

His product was popular not only for the quality and craftsmanship that went into them, but also because he kept the ‘Bulova’ name at the forefront of everyone’s mind. In 1926, the company was the first to air a commercial on the radio and then in 1941, it was the first television commercial ever to air.

Contests, endorsements and strategic advertising contributed greatly to the company’s success. By 1931, the company was spending over a million dollars on advertising.

Innovation
Joseph Bulova was an innovator when it came to making time-pieces more accurate and practical. His family carried on this tradition after his death in 1935. The most important advancement made was the creation of the Accutron, an electronic watch which became the most accurate method of time-keeping give or take 2 seconds.

This line is also the most expensive of all the Bulova watches and the technology uses a tuning fork that is activated by an electric charge, which eliminates the necessity for other tiny moving parts. The accuracy of this technology was so important, NASA commissioned the use of it in their computers and space equipment and the military also used it in timing devices.

Styles
Most of the collections have a men’s and a ladies’ model, but there are also some collections that are gender specific. The Bracelet collection is comprised of women’s watches that give the appearance of a bracelet instead of a watch. The band is thinner, more delicate looking. Some bands are even detailed with diamonds to give it a tennis bracelet look.

The men have collections like the Telluride that are very masculine and durable as well as stylish. Women’s and men’s watches come in gold tones, stainless steel, two-tone and even 14K or 18K gold. Leather bands adorn the casual sportier styles. Bulova watches utilize the self-winding method which means the movement of the body keeps the mechanism moving.

Kinetic or motion quartz styles are also available. These are also wound from body movement but they are also powered by it-no batteries are needed. Vintage Bulova watch may not have all the bells and whistles of the new models, but they are still quality pieces that were ahead of their time.

Anyone can enjoy the quality of a Bulova watch because there are so many collections at a wide range of price points. The Caravelle collection was developed in 1962 and it is the most affordable. The styles tend to be more trendy and contemporary, but because of the affordability, people can change their watch with the current trends.

Classic, contemporary, sporty, dressy, practical and luxurious-all of these words describe what can be found in the world of quality Bulova watches.

Talent Alone Will Never Be Enough (This Will Free Your Mind to do its Best Work)




“If you hear a voice within you say, ‘You cannot paint,’ then by all means paint, and that voice will be silenced” — Vincent Van Gogh

Creativity defines the human species — it underpins our favourite technology, music, arts and every other tool or product we use everyday.

The human mind is naturally creative, constantly looking to make associations and connections between things and ideas. It wants to explore, to discover new aspects of the world, and to invent. Don’t stand in the way of your creativity.

Most people view “creativity” as a talent. But that spark of genius can be nurtured and triggered using a variety of techniques.

In “Beyond Talent”, John C. Maxwell asserts that a person’s natural abilities are overrated and frequently misunderstood. While talent is an undeniable advantage, it accomplishes nothing by itself.

If talent is not paired with the right mindset and decisions, it wastes away and eventually evaporates. Everyone has an area of giftedness — something they do exceptionally well. However, the pivotal choices you make in life — apart from the natural talent you possess — will set you apart from the masses of people trying to skate by on talent alone.

In Talent is Overrated, Colvin argues that deliberate, methodical, and sustained practice is the way to achieve true mastery.

Now We Know Why Microsoft Bought LinkedIn




Six months after Microsoft announced plans to pay more than $26 billion for LinkedIn, we now know even more about why the career-focused social networking site was so valuable. Today, Microsoft revealed that LinkedIn founder Reid Hoffman has joined its board.

It’s impossible to overestimate the significance of this move for Microsoft. CEO Satya Nadella is three years into a turnaround that few people believed possible. When he was promoted to CEO in February 2014, Microsoft was in a bad place. Six months earlier, the company had posted its first-ever quarterly loss. Steve Ballmer announced he would step down, but before leaving, he pushed through the acquisition of Nokia. It was a costly mistake. Microsoft ended up paying $7.9 billion for the Finnish cellphone maker, according to an April 2015 SEC filing; the company wrote off nearly the entire sum in the final quarter of 2015.

Microsoft’s chief problem was this: Though the Redmond-ites made a lot of money, the company’s core business was declining, a dynamic that was set in motion more than a decade ago, when nearly every enterprise owned and ran Windows-powered PCs and servers. Microsoft had parked itself in the middle of Innovator Dilemma-land. The company had little incentive to invest in future businesses that might disrupt the business it was already in.

It also had a lousy reputation, particularly in Silicon Valley, where camaraderie and collaboration are hallmarks of tech’s evolution and every major player enjoys frenemy status with its adversaries. Microsoft wasn’t a company that partnered with outsiders. It scorned the open-source community and looked down its nose at tech upstarts. In a public conversation with Marc Andreessen in October 2014, investor Peter Thiel called Microsoft a bet “against technological innovation.”
