Time to get started. I will refer to it as the Hardwired Cell. A cell phone with or without cell service or a tablet to be the display, input device, GPS, and virtual TNC platform for this project. Even with a little markup on their part, that tells me that you can get a device pretty cheaply for this project.
My old HTC Evo? No problem. Not sure why. So my warning is, try your cable on a like device before you purchase said device for this project. A radio with VOX input. Be careful if you use a mobile radio. An audio cable that will tie into your chosen radio.
For those familiar with the Wouxun and Baofeng style adapter, you know there they use a 3. On my first try I harvested separate 3.
Melt, burn, scrape… try as I might, I was never happy with my ability to remove this coating and build a low resistance splice. Ultimately, I sacrificed an old hand mic like the one seen below. In addition to having the 3. As an added bonus, the cable retains its professionally made appearance. An audio connector for your phone. On most cell phones and tablets, the connection is known as a TRRS connector.
Take a look at the end of a fully featured headset… one that has headphones, a mic, and a remote built in line. Tip, Ring, Ring, Sleeve. I had a cable like this one already.
The same proviso applies from before. Of course, you can buy just the end, but at a lot of the places that I looked it was easier and cheaper to get a full cable and just cut off the end that you need. Plus, the premade ends look better.
A soldering iron is recommended to improve the conductivity of your splices. This is not required, though. Take it step by step. On the left side of the diagram you have the connection to the HT. On the right, the connection that goes into the headphone jack on your phone or tablet. Strip your wires and use your continuity tester to determine which wires inside the cables line up with the tips, rings, and sleeves on your wire.
Label and splice accordingly.
APRS – Hardwired Cell
Once spliced, make sure you check continuity from one end to the other to make sure no mistakes were made. Be sure to choose a size just slightly bigger than the splice you want to cover and slide the tubing onto the wire before you begin splicing.
Most manufacturers recommend a heat gun or heat shrink oven in order to apply even heat and limit the chance of scorching or lighting the tubing or surrounding insulation on fire. Note: Some hams who have built a cable such as this one have taken the additional step of adding resistors to the line to keep the cell phone or tablet from over driving the audio to the radio and distorting the packet. Plus, the cleaner your packet audio is, the more likely it will be that it gets decoded successfully.
The heat shrink tubing is covering the splice towards the top right corner of the picture. Enter in your callsign. This is to delineate between different stations that they may own.I want to connect a usb in port to a solar trickle charger the charger has a white and red wire and the usb in has a black red white and green wrapped in foil surrounded by copper wire how do I connect these I am trying to make a charger that will charge usb powered devices by solar.
Reply 5 weeks ago. I'm splicong a 4 wire charger in to a wire charger what wire s go to get her to make good connection for it to work. I'm splicing a two wire charger end to a four wire USB end charging cord. What wires go together for it to function properly. The part that goes to the cig lighter has white,blue light brown and black what wires do I hook up to a two wire one to make it work. My USB charger doesn't have blk what would be black then here are the color it has four of them red,white,green,blue.
Anyways the answer is that u only connect the black from usb to green from player, red to the red and the green and white wires left from usb dont get connected to anything. Maybe that's what you've got there? See also, the pinouts. Then it's red-to-red and black-to-black, and the green and white left unconnected. Or something like that It looks like there are some similar 'ibles in the related panel. You need to tell us how much time is remaining on the bomb before we can tell you which wire to cut.
If it's more than ten seconds it won't be dramatic and you're out of luck. You're outa luck!
Any answer without knowing what you're trying to connect and what was connected is just guesswork. And being wrong means you probably will ruin your phone and or charger. Follow Asked by monsterhung in Workshop. Tags: electical cell phone chargers. Reply Upvote. EricP 1 year ago.

A recent project has me dealing with some wired headsets. In the beginning there was the pocket transistor radio. When Sony got around to it some transistor radios featured a 3. This was intended to receive an earphone for private listening. An old school portable music player, like an iPod or my Sansa MP3 playerhad a single 3.
In fact, this type of audio jack was basically universal. It came into prominence with the first Sony Walkmanwhich was introduced in You can still see these sort of connectors described as 3. As these devices were used exclusively for listening to music, the pin out of the 3.
Since all devices used this wiring standard, basically any headset could be used with any player. Life was good. Well, it was basically good…unless you were involved in telephony or two-way radios. At least not as far as this 3. It needs to be wired in a fashion that considers the mono playback and the microphone. Many consumer DECT cordless phones use a 2.
While many business class telephones us an RJ-9 type connector for a headsetsome manufacturers do use 2. So now we have two standard ways of using this connector, varying only by application. Everyone is happy, even the call center staff. Since a smart phone can be used for both listening to music and making phone calls a 3-conductor connector is no longer adequate. In order to have both stereo music and a microphone signal a 4-conductor connector is required.
Enter the 3. Where things get interesting is in how the conductors are used. There was some initial disagreement about the wiring. In truth, the OMTP standard came first, it was Apple who mixed things up by insisting upon going another way. Nokia has somewhat thrown in the towel on its OMTP standard by developing a way for their second generation of Lumia phones to sense what kind of headset is plugged in and act accordingly.
So there can be some sense of peace, at least in the realm of mobile phones.Click on the image to enlarge it or click here for the Adobe. The resistance value comes from a long coil of wire inside each speaker called a voice coil. A voice coil is a coil of wire that, when placed inside a magnetic field, makes the speaker move and produce sound when driven by an amplifier. Speakers contain a long wound loop of wire called a voice coil.
This increases the amount of stress and heat it has to handle. For example, connecting a 4 ohm speaker to an amplifier that is labeled as working with 8 ohm speakers would mean it would have to produce double the electrical current to the speaker!
The recommended speaker impedance ratings are usually listed above the speaker wire posts. A home stereo, for example, may often list ohms as being ok for use.
Also, attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. Two 8 ohm speakers in parallel is equal to 4 ohms total that the amp will see. They ended up with a burned-out amplifier. An amplifier can only handle so much heat and stress before it fails, so be sure to observe these rules. Be sure you wire speakers to meet the minimum Ohm rating you need.
Speakers are different than other devices in that they work using alternating current AC instead of direct current DC. This is good news! As I mentioned, speakers work by moving a cone back and forth in order to produce sound. The result is a strange and poor sounding stereo.
When speakers are wired the opposite of each other sound waves cancel out. When wired the same, sound waves add together for more sound. Speakers that are wired differently sound poor because much of the sound is canceled out. So the most important thing here to remember is to wire speakers consistently the same way as each other. The job of a crossover also called a passive crossoverbecause it use basic capacitors and inductors rather than electronics is to restrict the music production each speaker tries to produce.
Unlike standard separate speakers, 2-way and 3-way speakers that have a crossover can only be used in parallel and not in series. This is because unlike separate speakers with no crossovers, in this case, many sounds will be filtered out. What this means is that little to no sound would be produced if another 2-way speaker is connected in series. In some cases, more speakers can be added to increase the amount of volume you can get or to place speakers in more rooms, more locations in your vehicle, and so on.
You also may have wondered what would happen if you bought an amplifier with twice the power of your present one. It increases a few decibels dB for each speaker added. This is because of how the human ear works and the physics of sound, along with how speakers work and how much volume they can produce for a given amount of power. Generally speaking, the human ear will hear a very small amount of volume increase for each doubling of acoustic power: about 3 decibels dB. For most people, the small amount of volume increase you notice when turning up a volume knob 1 notch is somewhere around 3dB.
It increases it a very small amount as far as your ears are concerned. Most people need an amplifier that can produce enough volume to fill a room or vehicle and turn up the volume from time to time.I learned so much about mapping. This is a fascinating topic and I wish you had a specialty just on that.
The professor was extremely helpful in the course and always willing to go above and beyond to answer questions. My statistical knowledge and base continues to increase significantlynow with each additional Statistics. I found the course to be a valuable introduction to resampling and bootstrapping methods. I am recommending this course to colleagues. Thanks for an engaging and informative course.
Considering all of the material that needed to be covered, I thought the course was well written and thought provoking. Overall, this was the kind of strong, structured introductory exposure to a topic I've come to expect at statistics. This is my fourth course that I have taken at statistics. I will continue to look for. I just completed another of your courses and yours is without question the best online educational resource available. Very happy with this course.
Taking as many courses through Statistics. I think the resampling approaches are refreshing and insightful. And the textbooks are marvelous in their clarity of expression and real world examples. I have told many of my colleagues about this wonderful and refreshing online medium for learning about statistics. Over the last two summers, I've taken the two stats courses meant to prepare future AP Stats teachers.
Those courses were invaluable to me and gave me the confidence I needed to tackle a difficult subject. I would like to thank you for offering such a chance for people to extend their knowledge in the fields of statistics, and consequently provide them the adequate tools for better performance and sound achievements in their jobs and research. As a SAS programmer, I believe I will continue to use SAS for data manipulation but will utilize R when running models and exploring large data sets.
I took the course to get starting using R, thus I think this will help with my use of statistics in the future. I really think these online courses are great. I need to know R to perform my job as I am a product manager for a software company that interacts with R. I am now able to understand R scripts and hopefully contribute some of my own. The instructor's videos were great.But smaller retailers can take advantage of this trend, too. Consumers are more and more prepared to give access to their data for a fair loyalty offering or personalized incentive.
Same-day shipping will become more prominent. The name of the new game. Consumers might not want to actually make the trip to physical locations, but they still want the instant gratification of taking their purchases home immediately. Is fulfillment feasible based on the location(s) of the retailer.
Retailers will continue to invest in omnichannel. Omnichannel is now the standard. In 2017, we can expect retailers worldwide to push their omnichannel strategies further than ever before in the pursuit of truly seamless shopping experiences. The retail world is rife with examples of this. Moving forward, these omnichannel efforts will be the difference between the retailers who succeed and the ones who fail. They also see the value in kitting out their physical space with a welcoming environment and paying more for experienced staff.
But when it comes to small businesses investing in their digital platforms (aka the backbone of day-to-day operations), cheaper or free have traditionally been the go-to solutions. Use a free appointment app to handle the bookings.
POS and inventory software. The value a business places on a digital platform tells its patrons everything they need to know about its true values. As digital platforms continue to become more powerful and interconnected, it gets easier for customers to see which businesses are authentically interested in their support.
Retailtainment will pervade the industry. Retailtainment assumes that people are more likely to engage with retailers who incorporate lifestyle elements into their stores, such as boutique coffee shops or virtual reality experiences.
Take iPic Theaters, for example. Data will continue to be a significant component of retail success. More and more merchants will recognize this which is why we think companies will double-down on data collection and analysis. JustFab is one example of a company that puts its customer data to good use.

JustFab also closely tracks the products each member browses, rejects, and buys and then uses data to curate selections for each member. Using data to personalize customer experiences is just the beginning. Data analysis also plays a major role behind the scenes, especially when it comes to inventory management and merchandising. Retailers rely on data to forecast demand and to make important stock-control decisions. Have a look at what clothing company Patagonia is doing.
Patagonia factors in current trends and historical data (among other things) to figure out which products to purchase and distribute in its stores. It influences so many important aspects of business: productivity, growth, innovation, and more. The volume and detail of data that companies are collecting, along with the rise of multimedia and social media use in retail, is only going to continue to fuel the growth of data in the future. Retailers will need to pay close mind to upskilling themselves and their staff to be able to analyze and understand the data they collect and how to use it.
Specialty stores will be more productive than department stores. Specialty stores those that focus on particular categories such as beauty products will have a leg up in 2017 as consumer interests focus in on curated selections and localized wares. Look for specialty stores to win in the coming year. Specialty stores also tend to provide better in-store experiences for their customers, with more knowledgeable staff, better prices, and more personalized service. By offering all this, specialty stores prove their advantages over department stores and develop direct relationships with their customers.
We can expect more of these changes but in 2017, specialty stores will reign. Retailers will turn to apps, services, and third parties to fulfill the needs of modern shoppers.
