Car Radio Installation

I do not do car radio installation. I offer better for a comparable price. Take the Time v3 Zero to Hero in Audio Tech class and understand how straightforward a car radio is and how similar a car radio is to most other consumer audio tech.

Bluetooth to phone is one tech feature worth having in your vehicle. If you have basic tools like screwdrivers and if you can strip and connect two wires together, I recommend installing your own Bluetooth radio. The radio itself is not so expensive. Allowing a shop to install is often more costly than the radio itself, but you can do it yourself in just a few hours.

How Difficult Will This Be?

By far the most difficult part of installing a radio in your car is removing the old radio and the dash around it. Everybody hates removing radios and dashboards. Some vehicles are very easy, others are difficult. Fortunately you can know how difficult yours is without touching your car. Just search on YouTube “[ vehicle make / model ] + remove radio ]” and decide if you want to tackle the project.

Watching somebody remove the dash on video helps you greatly by showing which panels must be removed, which are held on by screws, where the screws are, and which panels are snap-fitted.

Disconnect the vehicle battery first, it prevents making a mistake and blowing a fuse or worse, causing an electrical problem.

Which Radio?

Go to Crutchfield.com, enter your vehicle’s make and model, and Crutchfield automatically shows you radios that fit your vehicle. There are two main standard sizes, single DIN and double DIN.

If your car fits a double DIN radio, I recommend a Kenwood DPX504BT. (or a Kenwood DPX304MBT, same as the first but without a CD player). If your car fits only single DIN, I recommend a Kenwood KDC-BT278U.

  • These radios are not touch screen, so you use buttons while driving, which is more responsive, more convenient, and safer while driving.
  • These radios have an external microphone, which is a million times better call quality for the user’s voice, as in very very good versus often unacceptable for a microphone built-in to the radio.
  • These radios offer a quality Bluetooth connection, including dual phone connection, meaning a passenger can “DJ” while the calls go to the driver’s phone, for example. Once set up, they connect automatically when the radio comes on.
How to Physically Mount the New Radio?

Order the radio on Crutchfield along with the installation kit for your vehicle, which is usually included when you put the radio in your shopping cart online. The installation kit fits your car’s dashboard to the standard aftermarket radio size.

How to Connect the Wires?

The Crutchfield installation kit includes a wire harness made to adapt your vehicle’s harness to the standard wire coloring scheme of aftermarket radios. You can use their harness and just connect the matching color wires or you can look on the provided harness which colors go to what and connect the new standard radio wire harness directly to the vehicle’s existing wires for a better connection with no extra work. You will have to connect one set of radio wires no matter what.

I recommend soldering with a butane-powered soldering iron. Gas powered is much hotter than electric and more heat means easier and faster when soldering.

Ebola, How Bad?

No sources, but I am unaware of any dispute in the following quick summary:

Really Bad

  • Ebola causes internal and even external bleeding.
    • (The book The Hot Zone describes the virus “liquefying organs,” but this description is widely regarded as overly-sensational to the point of being inaccurate).
  • Very high fatality rate and recovered patients experience ongoing symptoms.
  • Ebola is known to lay dormant within individual human organs for many years.
  • The latest outbreaks are believed to have originated from recovered patients from previous outbreaks in whom the virus lay dormant for years.
  • Scientists believe it is theoretically possible for an Ebola virus to become airborne.

“Not So Bad”

  • As yet, Ebola has been contagious only by bodily fluid contact so outbreaks are almost always contained to just a few hundred people.
  • Infected persons are contagious only when symptomatic and the symptoms are too extreme to ignore. Little or no asymptomatic spread.

Mission

The mission of Time v3 Technology is to promote better implementation of existing technology with brilliance at the basics because less is more in technology.

Electronics Repair

While most modern electronics malfunctions and damage are difficult or impossible to repair, the right tools and know-how make some repairs worthwhile.

  • Watch battery replacement.
  • Maintenance and repair of select mechanical watches.
  • Screen replacement for select smartphones.

Consumer Consulting

As retail moves online, especially for electronics, consumers often lack basic information required to make a purchase among the myriad options. This is especially true when ordering accessories, customizing, or replacing parts. Good accessories can transform tech from useless to – useful.

  • Answer common consumer questions in blog post format to maintain online presence and streamline support.
  • Online conferencing audio equipment consultation for businesses.
  • Home audio equipment consultation. For example, parents enabling effective online classes for their kids, to include music lessons.

Zero to Hero Tech Concepts Education

Everyday tech remains a mystery to most people. Most people are starting at zero. Even if schools taught tech effectively, much of the tech did not exist when today’s adult generations were in school. The underlying concepts are both unbelievably simple and usually apply to a wide range of consumer products even if the products look very different. The underlying concepts behind modern technology are life education worth investing in. Plus, as users we are so familiar with everyday tech, it can be fun to see how it works.

1. Audio technology.

2. The internet. What the internet is physically. Demonstrate how we are communicating electronically from physical buildings to underwater cables to server software to web browsers. OstranderNet!

(Currently a draft post, more than half complete)

3. “Ownership and renting” on the internet. How the internet can be owned or rented just like real estate and how ownership is important on the internet just like in real estate. Vimeo versus YouTube, Linux versus Windows, domains and websites versus social media.

5. Home electric power. Electric power is a staple in the modern home. Simple demonstrations of what electric power is, where it comes from, and how it actually does things.

From Tesla versus Westinghouse/Edison to transformers to the AC waveform on an oscilloscope to watts and watt-hours to your circuit breaker box.

6. Data encryption. How can two computers send a message that can only be read by the two participants even if a hacker can see all of the traffic? OstranderNet.

7. Batteries. From lithium ion to lithium ion to lithium ion, performance measures and how batteries drive modern tech.

During the quartz crisis in Switzerland, Swatch bought Eta, who made 90% of the movements at the time. Swatch made movements nearly impossible to obtain for mechanical watches. Tag Haur and Breitling stood up to Swatch and bought movements from a new company, Saleta, who copied the movement from the old Eta.

Celestial Movement: Know Less Understand More

The following are true and do not change perceptibly over an entire human lifetime.

  • The non-sun stars do not move relative to each other. Not now, not over thousands of years, not anytime we will ever know about. The stars remain a fixed spherical image we gaze out at from the inside.
  • The north star and southern cross remain in the same positions in the sky and do not move relative to an observer on Earth, even as Earth rotates. They mark the axis of rotation of Earth. Correct, they do not move at all. You could build a structure pointed at the north star one night and if the structure doesn’t move, it points at the north star day and night season after season year after year forever, whether you can see the north star or not, it’s there. (The structure would be called a gnomon, if you care).
  • All of the non-sun stars/constellations remain in the exact same latitude and therefore trace the exact same line through the sky each time Earth rotates, every day of our lives, no exceptions. The line a star traces through the sky at your location peaks at 90° – [your latitude] + [latitude of the star] always.
  • Earth’s rotational axis is not tilted. Earth’s orbital plane around the sun is tilted! When orienting celestial objects, we are forced to choose what we consider “upright.” Earth’s gravity cannot dictate “upright” for celestial objects. If you imagine Earth’s rotational axis as upright, the north star remains fixed as “north” or “up” and the orbital plane is then tilted 23° meaning Earth “moves north and south” as it orbits, or moves “up and down.”
  • The sun. slightly more complicated, but helpful because the sun is bright. What is a line of latitude? What does a line of latitude look like? The blindingly bright sun traces a line of latitude through the sky every day. On equinox days, the sun traces the 0° line of latitude (celestial equator) and on the solstices the sun traces the +/- 23.4° line of latitude. In between, the sun gradually traces lines of latitude from 0° to 23.4° to 0° to -23.4° and back to 0° again throughout the year. Each day the sun traces a slightly different line of latitude as Earth orbits.
  • Nobody is good at three-dimensional spherical-angle geometry! Nobody! Astronomers are not good at it. Nobody is! Then why does the current zodiac constellation represent the constellation behind the sun that we cannot see?? Because nobody is good at three dimensional geometry! Astronomers for millennia past and still today use the sun as a “pointer.” Nothing in the sky points like the sun. The sun is such a bright “pointer” that you cannot see what is behind it – but remember that the stars do not move relative to each other so if you have some idea of what the starry sky looks like, and you know the current zodiac constellation, you can reference the rest of the starry sky off of the sun itself. “Pisces is shining bright this month!” True statement – even though Pisces is only up during the day because looking forward the sun means looking toward the current zodiac constellation. We are currently in Pisces. “The sun pointer is moving toward the constellation Aries.” Another true statement. The line the sun traces through the starry background as we orbit is called the “ecliptic.”

Once you have some firm ground to stand on, you can start to remember some more basics and build. If you get confused, re-read the above and remind yourself that many things in the sky do not change!

  • Orion, the most widely-recognized constellation, is on the celestial equator. Therefore Orion rises directly east and sets directly west. Orion is “up” ~12 hours and “down” ~12 hours. Orion’s path peaks at 90° – [your latitude] above your horizon (directly overhead the equator). Also, Orion is visible from everywhere on Earth.
  • Orion is directly south of the border of Taurus and Gemini. The Taurus Gemini border marks the northern hemisphere summer solstice, so on the summer solstice the sun points near Orion. On the winter solstice, Orion is high in the sky at midnight.
  • Polaris, the north star, is located directly north at [your latitude]° above the horizon, always. Most people use the Big Dipper to find Polaris.
  • The two stars in the Big Dipper aligned with Polaris point to the ecliptic at Leo near its border with Virgo, so near the sun’s location at the autumnal equinox.
  • The Milky Way’s bright galactic center is among Sagittarius, specifically Sagittarius A. It is 29° south of the celestial equator so therefore peaks at 61° – [your latitude] in your sky (more visible in southern hemisphere). Being near the northern hemisphere winter solstice, it is most visible in northern hemisphere during summer.
