Power SourceInstructables user luxstar covered the detailed process of recharging a car battery with a solar panel for emergency backup power.
This will be a tutorial on how to make a beginner 555 timer chip circuit to pulse a led on and off. Ever had a need for a replacement or project power supply that you just can't find anywhere or costs way to much? Hello friendsToday I am back with another project called ultra cheep home automation under $5Home automation means you can control home applies more easily. This project probably started due to my odd obsession with quarters and coin operated devices. I found a website whilst searching online which documented some experiments done with printed circuit boards with a serpentine pattern etched onto them, To use them as a heater. A couple of years ago, I purchased a second hand GameBoy Color from a flea market so I could kill some time.
In this instructable, I'll go over what a printed circuit board is, where they are used, and the basics of how to make one yourself. I just bought a heat gun and shrink wrap from Harbor Freight, and I was totally blasted with the usefulness of shrink wrap.
A NAS or network attached storage, is the best way to keep your data backed up and stream and access content from all the devices connected to the network. After fixing up the cabinet to this radio and enjoying staring at it for awhile, it is finally time to take a whack at the chassis.
I have some broken small RC car without remote control and I was interesting to hack the H-bridge of these car and connect them to micro controller circuit  in order to make for example a line follower robot or obstacle avoidance robot.
This is a very simple hack that will allow your older radio to play from an auxiliary input.
The Kindle Fire is a great way to engross yourself in a good book or enjoy a nice game of candy crush without the need of a big book or a heavy computer. I saw one of these mirrors online and instantly set out to make one in the cheapest, thriftiest and easiest way I could find and now you can too! The purpose of this circuit is to test NPN and PNP transistors and to identify their pin layouts, ie ECB, EBC. Target Audience This is intended for anyone who wants to simply and cheaply make a generator for a square, triangle or blended waveform that can be frequency and amplitude adjustable.
In this project I will show you how to create a Boombox that mainly consists of a car radio, salvaged speakers and two 12V lead acid batteries.
Did you make a mistake while programming fusebits, or purposely disabled reset pin (RSTDISBL) or ISP programming (SPIEN)? A weather station is a fun project that teaches you a ton about electronics with the added benefit being an actually useful little device. A little while back I got very excited when an instructable came up that was a so-called cassette tape mp3 player, but I was quite disappointed when I found out that it was just sticking an mp3 player into a cassette body.

Surgeons at Massachusetts General Hospital in Boston performed the first penis transplant in the US earlier this month, The New York Times reports. If everything goes well, the recipient, a bank courier named Thomas Manning, will be able to urinate normally within a few weeks and regain sexual functions within weeks to months.
Last week, the planet Mercury put on a show for astronomers by trekking across the Sun for 7.5 hours. Garmin just announced the new Vivosmart HR+, an upgraded version of one of the company's flagship wrist-worn fitness trackers.
Like its predecessor, the new version of the Vivosmart HR+ is water-resistant, has a black-and-white display, and tracks steps, distance, calories burned, and heart rate. Astronaut David Saint-Jacques will be the next member of the Canadian Space Agency to go into space. Fox announced its fall and mid-season TV schedule this morning, revealing new information on a handful of highly anticipated reboots and adaptations premiering in the next year.
I was the first of my friends to have a system like that, and so when any of them came around to watch a film on my system for the first time, what did I put on? When Nintendo announced the Mario mash-up pack for the Wii U version of Minecraft, it revealed a slate of Mushroom Kingdom-themed content for people to play around with. The prebuilt world was created by developers Mojang and 4J using the various elements that come in the new mash-up pack.
Lyft has agreed to more than double its settlement in a class action lawsuit in California after a judge rejected a $12.25 million deal as too small. The settlement echoes a similar deal between Uber and its drivers in California and Massachusetts.
Video game movies are notorious for spending eternity in development hell, but this one's actually happening: here's the first trailer for Assassin's Creed. BBC’s Attenborough’s Life That Glows is an absolutely gorgeous look at the mysterious creatures around the world that have bioluminescent powers.
Painting a wall is boring because it takes so much time and requires so much preparation to not get paint everywhere. Superheroes have superpowers and exist in worlds where reality doesn’t exactly exist and have weird names and are totally not all the way human.
A crowd of wealthy investors, transportation experts, media, and even North Las Vegas Mayor John Jay Lee, watched as a roughly 10-foot long sled shot down a short train track and then crashed into a pile of sand.

To check your battery's state of charge, connect the RED or POSITIVE voltmeter test lead to your battery POSITIVE terminal.


The photo at the top of this page shows a battery voltage reading of 12.29 volts, which means the battery being tested is low with only about half a charge. If your battery voltage is less than 12.45 volts (75 percent charged), it is low and should be recharged.
Automotive lead-acid batteries should be maintained at a 75 percent charge level or higher for best performance and life. A good battery is essential for reliable starting, especially during cold weather because cold weather increases the cranking load on the battery. Warning: Do NOT attempt to recharge your battery if it has run down and the liquid inside is frozen.
A GOOD battery is one that will accept and hold a charge, and is capable of producing close to its rated amperage output. Most car batteries only last about 4 to 5 years, so if your battery is 4 or more years older and is not holding a charge (keeps running down), or it does not seem to crank your engine a normal speed, you probably need a new battery. A low or dead battery does not mean your battery has failed, or that it needs to be replaced. CAUTION: Conventional wet cell car batteries are filled with a mixture of water and sulfuric acid. The other (and must faster) method for testing your battery is to use an electronic "conductance" tester like the one shown here. Some electronic battery testers can also analyze the battery's CCA capacity, which can be used to estimate the battery's remaining service life. Diagnostic Tip: You also can use a digital voltmeter to check for voltage drop across all circuit connections, too. Whether your battery tests GOOD or BAD, make sure the battery is fully recharged before returning it to service. Diagnostic Tip: If the alternator on your car has failed, it might mean your battery is not building up normal resistance as it accepts a charge. A replacement battery must have the same post configuration as the original (top post or side post), and fit the battery tray.
Next, you have to figure out how many CCAs the vehicle needs for reliable cold weather starting.
Another number that is important is the months of prorated warranty coverage provided by the battery manufacturer. This, in fact, isn't true—the majority of "dead" car batteries just don't contain enough juice to power a car, but they can still provide enough watts to keep emergency fans and lighting running, which is great when a power outage occurs.
In order to turn this mess into a manageable and easy to understand circuit, one must have a good understanding of a few basic electrical circuit components. This is a very easy circuit, all you need to know is basic electronics and how to use a breadboard.
This instructable will teach you to take junk wall warts from thrift stores and hack the circuit to give you what you need. Unfortunately, I hadn't thought about buying cartridges for it, so I started looking up how much a GameBoy flash cart which could store various games at once would cost. So sit back, strap in, and enjoy learning about this very important and interesting method of making electronics!Note: this is an introductory guide. It worked fairly good as it was but it had a hum that was always in the background which gets pretty annoying after awhile. I have found the circuit of this project in a book I bought eighteen years ago when I was in high school. All that you have to do is turn the Axle of the generator using a mechanical outside source of energy . This upgraded version is louder and lighter than my previous Boombox and can play its tunes up to 9 hours continuously. The goal was to regulate the temperature inside the greenhouse thanks a lamp, a servomotor to open a window and a PC fan. This Instructable replicates a DC electric demonstration motor I made about two decades ago for my own children. No need to buy or make inconvenient HV programmer only for unlock couple of Tiny AVR’s. The project requires a bunch of cheap parts and sensors totaling less than $15, and the whole thing ends up fitting in your hand.

The groundbreaking procedure, underwent by a 64-year-old patient whose penis was removed because of cancer, could be used to help injured veterans, cancer patients, and accident victims.
In what is known as a Mercury transit, the tiny planet passed between the Sun and Earth, appearing as a tiny black dot moving slowly across the Sun's bright disc.
The new model comes with a GPS radio, and is now able to automatically detect and track your activities thanks to the inclusion of the company's Move IQ software.
Today the company announced Spaces, an app for Android, iOS, and the web that's designed to make it easier to share, well, stuff from the web in group conversations. Navdeep Bains, Canada's minister of innovation, science, and economic development, announced today that Saint-Jacques will travel to the International Space Station in November of 2018.
It was that mixtape — a 13-track collection of druggy and ecstatic hip-hop so goofy it sometimes sounded like nursery rhymes — that propelled Chancelor Bennett from underground Chicago upstart to slightly less underground Chicago upstart.
Back when the film first came out in 1986 (30 years ago today), I’d just bought myself a large Sony TV and a state-of-the-art Sony VCR and amp, which meant I could watch films in loud, stereo sound.
The game will get 40 character skins, so you can dress up as Mario or Peach, and you can change the look of surfaces so that they will seem as if they came from the Mario universe. Drivers for the service argued that they'd been misclassified as independent contractors, rather than employees, and are set to receive $27 million under the revised settlement.


The movie doesn't appear to take too heavily from any of the games in particular, but it's very much in line with the series' usual tropes — the plot sees Marion Cotillard send Michael Fassbender back to the time of the Spanish Inquisition to alter the genetic memories left by an assassin ancestor.
It details the lives of fireflies, glow worms, fungi, fish, squid, plankton, and other creatures, and shows how they use their glow-in-the-dark abilities. But what if it could be exciting and done quickly and the point was to get paint everywhere?
Hyperloop One, the LA-based startup striving to realize Elon Musk's pipe dream, conducted it's first public open-air test in the Nevada desert Wednesday. It was an inauspicious way to kick off what's supposed to be a global revolution in transportation. This aerial view, courtesy of a drone, captures something not often seen: a pod of false killer whales (which are a species of dolphins, of course) chasing and hunting down a shark in the waters near Sydney, Australia. Johnson hopped onto Instagram this afternoon to confirm reports that Black was joining the Jake Kasdan-directed reboot, which is scheduled to land in theaters sometime next summer. The best car battery chargers can quickly juice up your battery, getting you back on the road.
Some testers can also measure the amps drawn by the starter while cranking the engine, and analyze charging system output under load once the engine is running.
This, in turn, makes the alternator keep charging the battery at a higher than normal rate. As a rule, the higher the warranty months on the battery, the higher the battery CCA rating and the better the battery.
Though all automotive batteries today are still based on lead-acid chemistry, redesigned grids, thinner plates and new connectors allow more amps to be packaged into smaller cases. It measures low current draw for 20 hours while maintaining a minimum post voltage of 10.5 Volts at 70 degrees F.
Also, check the negative battery cable ground connection and the integrity of any engine ground straps. So, instead of lugging the battery to the nearest drop-off center or just letting it collect dust in the garage, you can put that car battery to good use. Most of the available FM transmitter circuits have, in my opinion, a very important drawback: the use of inductors. The drawback is that to directly convert light to electrical energy requires a solar transducer such as a solar panel. I love prototyping on a bread board as well as salvaging parts from pre - existing circuits. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
No return or exchange will be accepted after 30 days from the date of you receive the item. It's an event that happens only about 13 times a century, so astronomers were out in full force with specialized telescopes to observe the transit. That means you could take off for a run without hitting any buttons and, when you return, have an accurately-mapped record of your workout. These are called "otoacoustic emissions," and they happen when the specialized hairs on and inside the cochlea — called hair cells — vibrate either spontaneously or in response to auditory stimulation. His star rose quickly as the months passed, performing at big festivals and collaborating with artists like Justin Bieber, Kanye West, and Jeremih. A series-length contemporary version of The Exorcist starring Geena Davis and Alfonso Herrera will possess Fox's Friday nights alongside a new season of Hell's Kitchen, and a new take on Lethal Weapon starring Damon Wayans will lead into new episodes of Empire on Wednesday nights. This is roughly 17 percent of the $156 million sum that attorneys say the drivers could have recovered had they been recognized as employees. He also confirmed that Kevin Hart is part of what he termed "the Jumanji Breakfast Club," a casting that's been rumored for weeks. So consider upgrading from a basic 36-month replacement battery to a premium 72-month battery.
AGM technology also makes batteries more resistant to vibration damage and helps extend battery service life.
Scientists have known about these emissions for a while and they use them to screen newborns for hearing problems. Acid Rap’s long-awaited follow-up, Coloring Book, came last week, and it’s easy to feel the time that’s passed between the two. Neither show has a specific premiere date yet, but they're on track to start airing sometime in September. Those four minutes were a movie; a beautifully crafted, adrenaline-filled, self-indulgent tribute to the raw speed and power of flying heavy metal. But it turns out there’s more coming to the game than just tools for creative Mario fans: there’s a whole new world to explore that pulls together elements from virtually every Mario game for a huge dose of nostalgia.
On display was proof that Elon Musk’s dream of a transportation system that breaks the barriers of speed and time was a step closer to reality.
But now, an Australian startup called Nura claims to have created headphones that can pick up and analyze these emissions to optimize the listening experience.
For one thing, Coloring Book was released as a two-week Apple Music exclusive instead of a free download, as his past mixtapes were. The news comes via Peter Rojas, who tweeted that this headset will be “less powerful” than a Vive or Rift, but won’t require a phone to power it along like the Gear VR. In short, the headphones work like self-regulated equalizers, customized specifically to a listener's ears. Android VR will definitely be announced next week, and from what I’ve heard will be less powerful than the Vive or Rift.
If accurate, that means the familiar ‘Okay, Google’ command would be available throughout your home, all the time.
