Electronics, Prototyping, Open Source, and Capitalism

by on Oct.28, 2016, under USA #1

While recovering from an illness (double pneumonia) almost ten years ago, I managed to do a significant amount of reading. There was a growing list of books I’d seen referenced (many while reading the “Rich Dad / Poor Dad” series) that I had long had intentions of reading. The list included such works as “The World is Flat” by Thomas L. Friedman, “Tipping Point” by Malcolm Gladwell, and “Wikinomics” by Anthony D. Williams and Don Tapscott. These books had great impact on my perspective, and as a result my, “post recovery” path forward.

The “Rich Dad / Poor Dad” series left me determined to pursue being a business owner – “minding my own business”, as Robert Kiyosaki put it.

“The World is Flat” opened my eyes to how the world was changing as a result of the Internet. “Tipping Point” enlightened me about how the mechanism of change was occurring in today’s world.

In “Wikinomics” I learned the role the “wiki concept” would play in leveraging the input of virtually anyone, in solving virtually anything. I had heard of “Open Source” before, and had a vague understanding, but my understanding was broadened by the “wiki concept”.

Being a Patriotic American with a strong belief in the benefits of Capitalism, although I saw the light with respect to these concepts, they were somewhat confronting. Having worked for General Electric during the tenure of “Neutron Jack” Welch, I was tasked with “protecting the family jewels”, as in “proprietary information”. So, concepts involving the sharing of information regarding developments was a stretch.

Meanwhile, seeing the reality of a developing Global Economy, and the participation of those far beyond Our shores, clearly long held concepts were going to be challenged. Having become interested in solar power, I had begun paying close attention to the manufacturing capacity for solar cells developing worldwide. This emerging solar marketplace was an example of a product’s refinement and production occurring in the competitive global economy.

Creations developed and refined on an “open source” basis leveraged by the Internet, are certainly going to continue to be a formidable challenge to past attitudes toward proprietary information.

Consider the Arduino microcontroller, developed and refined on an “open source” basis, making it not only possible, but within relatively inexpensive reach for individuals worldwide to prototype and test their problem solving gizmo.

The initial development of the Arduino microcontroller emerged in followup to “Wiring” and “Processing”. In 2001, Casey Reas and Benjamin Fry started “Processing” (a processing language based on Java). “Processing” was developed with the intention of getting non-programmers programming, via a digital sketchbook to facilitate them trying and experimenting with their ideas. In 2003, Hernando Barragan began developing a microcontroller called “Wiring”, with the intention of getting people involved with electronics. Then in 2005, Massimo Banzi and David Cuartielles embarked on the development of the Arduino microcontroller.

Being an Engineer, I’ve always been intrigued by Electronics, but haven’t had occasion to delve very deep into actually assembling electronic components into a functioning apparatus.

Most of my career spent in oil, chemical, and nuclear power industries, has been in plant construction and maintenance. Both construction and pipe replacement projects had me involved in welding. Due to the radiation exposure, more specifically – remotely controlled (from a clean environment) automated welding aided by video and audio. Electrical equipment later became another area of specialty.

Ultimately, I came to carve out this niche around SAE 2 Pin connectors and connector assemblies in a wide range of configurations – especially heavier gauge conductors.

More recently coming to be more familiar with the Arduino microcontroller, I’ve become all the more intrigued with electronics.

Clearly, a focus of mine are applications in which an SAE 2 Pin connector assembly will fill the bill. Certainly, power circuits for apparatus controlled by a microcontroller will precipitate applications for SAE 2 Pin connector assemblies.

As the Premier Supplier of SAE 2Pin Connector Assemblies, a mission is to assist the interested by facilitating pertinent interaction. The intention is to open eyes to possibilities, inform, and educate, as well as facilitate. As in facilitate the sharing of knowledge by those possessing it, and encourage the asking and answering of questions.

We look forward to comments from a diverse group of interested contributors, and welcome questions and suggestions, as well!

DC Connector Terminology

by on Mar.09, 2012, under Terminology

Whenever one choses to delve into a technical topic, it’s worthwhile to begin with a study of pertinent terminology.  Generally speaking, it won’t be long before you start bumping into terms that are key to gaining an understanding.

The handy SAE 2 Pin connector is a great example.  We all had some exposure to basic electrical concepts in our early years, but not everyone has experienced continued exposure throughout their life.

If you were to begin looking for some information on the SAE 2 Pin connector, you’d probable come by it being described as a type of “DC connector”.   Now many are reminded of the terms AC and DC by the name of one of my favorite bands.  Some people might understand that what they access at a household electrical outlet is AC, and maybe even that AC stands for “alternating current”.  I hesitate to think that very many people actually have a firm grasp on just what “alternating current” means, let alone – “DC”, and “direct current”.

I’m not poking fun at anybody.  Many of us are very knowledgeable about areas of technology without any reason to have this particular knowledge.  An engineer, and the son of an electrician (early in his career), I’ve had quite a bit of exposure to electrical concepts throughout my life.

Direct Current (DC) being that which pertains to the topic of SAE 2 Pin connectors, that will be our focus in this discussion.  Any discussion of DC vs. AC is going to involve explaining that the “direct” vs. “alternating” pertains to the direction of the flow of electric charge.  Direct Current (DC) is the flow of electric charge in one direction.  Alternating Current (AC) is the flow of electric charge in both directions, i.e., “alternating” one then the other.

Alternating Current (AC) is what we access at household electrical outlets, but it also describes that which is produced by an Alternator.  An alternator converts mechanical energy (the belt driven rotation) to electrical energy in the form of alternating current.  An electrical device called a rectifier converts alternating current (which periodically reverses direction), to direct current (which flows in only one direction).  A rectifier produces a type of DC characterized by pulsating voltages and currents.  This type of DC current may then be further modified into the type of relatively constant voltage DC characteristically produced by such sources as batteries and solar cells.  There’s a lot of room for further discussion along these lines.  For our purposes, let’s leave it at the above for now.

As stated above, it is Direct Current (DC) that is produced by a battery.  It is direct current that used to charge batteries, as well.  Most electronic systems employ a DC power supply.  It follows then that a “DC Connector” is an electrical connector used in supplying Direct Current (DC) power.  There are numerous standardized DC Connectors with specific dimensions and configuration to prevent accidental connection of incompatable sources and loads.

An important aspect of a connector is its “Pinout” – which describes the function of its contacts (or “pins”).  That function may be Power (“+” positive, or “-” negative/ground), or Signal related (as in the case of a USB connector with “+” Data and “-” Data contacts).

When it came time for battery maintenance industry leader, Deltran, to select a DC Connector for the output of their Battery Tender line – the SAE 2 Pin connector was no doubt the hands-down choice.  Common in the automotive industry, its selection by battery maintenance equipment manufacturers makes sense.

Most peoples’ likely exposure to the SAE 2 Pin connector probably has to do with its use in trailer light systems.  SAE 2 Pin assemblies can often be found in the trailer lighting section of automotive stores.  Hopkins Manufacturing (the name you’re likely to most often see associated with trailer light wiring products), calls these 2 Pole Flat connector assemblies – Product No. 47965.

It was then likely to follow that upon development of Portable Solar Chargers, the SAE 2 Pin connector was to be the choice.  Industry leader, Global Solar, chose the SAE 2 Pin connector for the output of the majority of their SUNLINQ line of portable solar chargers.  In fact, their 6.5W and 12W models feature a 5-piece SAE 2 Pin accessory cable kit.

These two applications give rise to the next topic – “polarity”.  Polarity being which side of a particular connector is “hot” (+) positive, and which side is (-) negative.

In the case of Battery Tenders, the connector polarity is driven by the necessity for it to be the “protected” female side of the SAE 2 Pole connector at the end of the assembly connected to a vehicle battery to be the “hot” (+) positive side.  Therefore, the exposed pin side of the SAE 2 Pin on the end of a Battery Tender output must be “hot” (+) positve.

Portable Solar Chargers are a different situation, since the solar cells are a power source.  Their output connection must therefore be of the polarity which will have the “protected”  female side of the SAE 2 Pin connection being the “hot” (+) positive.  Accessory assemblies must then be of a polarity in which the exposed male pin of the SAE 2 Pin meant to be plugged into the output connection of a portable solar charger must be the “hot” (+) positve.

Anyone connecting leads in circuits such as those discribed above must be carefully mindful of polarity.  There may even be times when it is necessary to use a multi-tester to confirm polarity.  The continuity test function of a multi-tester can be employed to determine which contact (or pin) on the connector at one end of a lead is mapped to (leads to) which contact on the connector at the other end.

Well, we’ve covered quite a few electrical terms and concepts – enough for now.

SAE 2 Pin Defined

by on Feb.08, 2012, under Terminology

As indicated by the “SAE” aspect of this connector’s designation, the specifications for this connector were developed by the Society of Automotive Engineers.  Learning that, we are quick to realize this connector was (at least initially) intended for use in automotive industry applications.   Therefore, the SAE 2 Pin Connector was developed for use in DC (Direct Current) circuits – most often 12 Volt DC.  So in the world of electrical connectors, the SAE 2 Pin Connector would be loosely defined as a type of “DC Connector”.

Further defintion of an SAE 2 Pin might include the description “hermaphrodite” two conductor DC connector.  The term “hermaphrodite” is applicable because each connector includes both “male” and “female” components – an exposed “male” pin, and a protected “female” socket.

An SAE 2 Pin Connector is often seen on the output of battery maintenance equipment, such as the industry leader – Deltran Battery Tenders.

Therefore, the associated accessory assemblies are outfitted with an SAE 2 Pin connector of the polarity necessary to carry out the intended function.  For example, a Deltran Battery Tender “Quick Connect” assembly, to which a Battery Tender output can be coupled to maintain a motorcycle 12V battery’s charge during periods of little or no use.

Thus far in this post, we have focused on the term “SAE 2 Pin”, but this connector is often given other names – SAE 2 Prong, SAE 2 Pole, SAE 2 Conductor, 2 Pole Flat Trailer Connector, etc.  It’s pretty clear that “SAE 2 Pin’ is indeed the appropriate terminology, based on the connector’s specification developer (SAE – Society of Automotive Engineers) and this term’s consistant use.

 

The SAE 2 Pin connector has surfaced as the predominant choice in the portable solar charger industry, as well.  For example, Global Solar’s SUNLINQ 6.5 and 12 Watt portable solar chargers have an SAE 2 Pin connector on their output cable.  The associated accessory kit consists of 5 cable assemblies with SAE 2 Pin connectors.  The polarity of these assemblies is specific to their use coupled to the output of the 6.5W or 12W portable solar charger.

Deltran’s 5W, 10W & 15W Solar Panel powered Battery Tenders feature and SAE 2 Pin output, as well.

The predominance of the SAE 2 Pin connector in 12 Volt DC applications is prompting a growing assortment of cable assemblies and adapters.  For example, SAE 2 Pin x COAX adapters.

SAE 2 Pin connectors are being made available in a wider range of wire gauge, as well.  Heavier AWG leads are facilitating greater current carrying capacities, and thereby use in higher current flow applications.

Replacement SAE 2 Pin Connector Cap – Made in the USA !!!

by on Feb.08, 2012, under Caps

One often heard request was for SAE 2 Pin “Caps”, which we took on answering.  Our searches for a supplier came up empty handed, so we endeavored to manufacture one.

Of course, that involved the development of a mold.  Never-the-less, willing to go the distance – we made that investment.

So, here’s a look at them:

 

Because we’ve manufactured them with a relatively soft rubber, they are easily manipulated onto a connector – and they remain in place.

 

 We’re pleased with this product, and able to offer quantities at a very reasonable cost.

American Made Surface Mountable SAE 2 Pin Connectors

by on Feb.06, 2012, under Mountable

We now have our own Surface Mountable SAE 2 Pin Connector Assembly to offer – another quality Bohemian Biker LLC product  manufactured right here in the United States !!!

Initially, we found and provided an Surface Mount SAE 2 Pin assembly that was “polarity specific”.  That is, it had red and black insulated leads and was most readily available in one polarity.

This “polarity specific” assembly had 12 AWG leads, which seemed to be an adequate choice in terms of ampacity (current carrying capacity) for many do-it-yourself applications.

Quickly recognizing its popularity, we set out to develop our own SAE 2 Pin Surface Mount assembly.  Ours has 12″ of Black cord, such that the installer has the latitude to choose the polarity without violating a “hot” (+) positive wire insulation color standard.  The black cord of our product not only provided the benefit of “polarity of choice”, but the added aesthetic value of “all black” desirable in many applications.  An added benefit of this softer black cord is its flexibility, a desirable feature in many applications.

The ability to solidly mount an SAE 2 Pin connection on a soft (such as in the case of a motorcycle tank bag) or rigid surface (such as in the case of a plastic motorcycle saddlebag case), can be of key importance in many do-it-yourself applications.  It not only has advantages in terms of convenience, but also often in terms of security and sealing out moisture.

Some might also refer to this form of SAE 2 Pin connector as a “bulkhead connector”.  In an application where you have multiple compartments (in, for example, some sort of an enclosure, or box), one of these “surface mount connectors” could be used as a “bulkhead connector”.  A “bulkhead” being a wall or barrier between two adjacent compartments.

Just like the model we found initially available, ours has a tethered cap – which is a cool feature.  A surface mount’s “inset” configuration provides some inherent protection, but the protection added by a cap if often appreciated.  A cap adds to aesthetics when the connection is not not in use, as well.

American Made Heavy Duty SAE 2 Pin Assembly Variations

by on Feb.05, 2012, under HD Variations

Having taken on making our niche SAE 2 Pin connectors, the idea of developing a wide assortment of heavy duty variations occurred to us.  Not long after developing and manufacturing our initial offering we began addressing heavier AWG assemblies.  In this post, we will discuss the variation stages we have ventured through thus far.

Note:  All of these products are manufactured here in the United States.

The first offering manufactured by us was the assembly below – high quality SAE 2 Pin connector with enhanced strain relief and 11-1/2″ Black of SPT-1 cord with 18 AWG leads.  These proved popular with do-it-yourselfers wiring up light accessory circuits, etc.  Following that came that same SAE 2 Pin connector with 5 feet of Black SPT-1 and 16 AWG leads.

 

 

 

 

 

 

The first of our heavier duty line to be developed and manufactured was SAE 2 Pin pigtail assemblies with 12 AWG leads – 12″ long.

 

               

 

 

 

 

 

These were welcomed by do-it-yourselfers, as well – especially with solar enthusiasts, amateur radio enthusiasts, and others with a desire for SAE 2 Pin connectors with up-sized leads.

Initially, we manufactured this product with lead insulation colored red and black.  We called the pigtail “Power Side” when the red insulated wire lead to the protected “socket” side of the SAE 2 Pin, and called it a “Load Side” pigtail when the red insulated wire lead to the exposed male pin side of the SAE 2 Pin.

Next to be addressed was SAE 2 Pin pigtail assemblies with 10 AWG leads – 12″ long.

 

 

 

 

 

 

 

We chose to stick with black insulated/separate 10 AWG cables vs. red/black insulation – thus leaving polarity up to the installer.

Those two variations in hand, we were quick to follow with SAE 2 Pin “whip assemblies” 5 foot long leads in both 12 and 10 AWG.  Again, we choose to stick with black insulated/separate cables vs. red/black insulation.

 

As you can imagine, applying an SAE 2 Pin connector to the far end was right around the corner.  So, we started cranking out SAE 2 Pin Extensions with black insulated/separate 10 AWG cables – 5, 8, and 10 foot long.

Basics of SAE 2 Pin Connector Assembly Polarity

by on Feb.04, 2012, under Polarity

Whenever one contemplates use of SAE 2 Pin connectors, an understanding of, and attention to, “polarity” is vital.  Vital in terms of safety, and avoiding possible damage to components.

For the novice (and those who have forgotten) – “polarity” means identifying the “hot” (+) positive side of the connector vs. the negative (-) side.

When there are leads of different insulation colors, say red and black (or white) – the red insulation by standard indicates “hot” (+) positive.

Understand this is a standard, but one should always test to confirm.  Such a test would entail connecting a voltmeter contacting the end of this red insulated lead at the connector and ground.  If there is a voltage indicated (probably 12 volts), then we have confirmed this is indeed the “hot” (+) positive side.

Obviously, with respect to the (-) negative side, the opposite would be the case.  In accordance with standard, this would be indicated by an insulation color other than red – usually black, or white.

Understand that there are times when a color other than red is used to indicate “hot” (+) positive.  For example, if there are several “hot” (+) positive wires (such as in the case of car stereo wiring, i.e., radio power, and keep alive power for memory) a color like yellow might be a “hot” (+) positve wire.

Another application in which there will be multiple “hot” (+) positive wires would be in a trailer light wiring harness and at the vehicle’s disconnect plug.  Even for simple trailer light wiring systems, there may be three “hot” wires – each for various lights (running lights, turn signals, brakes).  Of course there will be a ground (usually black) shared by each of these individual circuits.  In fact, the metal trailer frame is the ground for individual lights in many cases.

While on the subject of trailer lights, it should be noted that this an application in which the SAE 2 Pin connector can be found.  In fact, it is often called a “2 pole flat trailer connector”.  12″ red and white extensions with these connectors can be readily found in the trailer hitch (trailer lights, wiring and connectors) area of your local discount automotive store – most certainly Hopkin’s products.  These are great, certainly filling the bill in many other light applications.  “Light” meaning low current applications, since the wiring is generally 16 or 18 AWG.

These extensions are true “extensions”, i.e., properly connected, you end up with the polarity you started with… at the far end of the extension.  …if the red “hot” (+) positive wire is leading to the female side of the SAE 2 Pin you want to extend 12″… upon coupling the end of one of these 12″ extensions with the red wire leading to the exposed male pin…  the opposite end will have the red wire of the 12″ extension leading to the female side of the SAE 2 Pin at the other end.

Hello world!

by on Feb.04, 2012, under News

Welcome to our new SAE 2 Pin website !!!  Created to increase awareness and knowledge of the handy SAE 2 Pin connector, our Blog format facilitates interaction along these lines.

We have several years of experience focusing on SAE 2 Pin connectors, leads, and cable assemblies through our other two websites: www.bohemianbiker.com and www.solarcapitalist.com  Where there had been limited attention, we developed and manufactured SAE 2 Pin assemblies with heavier gauge leads (14, 12, and 10 AWG vs. only 18 and 16 AWG).  Worth noting – the high quality SAE 2 Pin assemblies we have developed are manufactured right here in the United States.

It is our mission to post that which we’ve learned, provide this forum through which others may contribute their pertinent knowledge, and have this same forum also allow all to raise questions in the form of posts and comments.  Thereby, making this accumulation of posts and comments available to all those with an interest.  We welcome your active participation!

Always with an eye on that which will please our audience, we are vigilantly watching for emerging needs.  Where a custom SAE 2 Pin connector assembly is required (even with a different connector at the opposite end) please contact us to discuss it’s potential development and production.  We are well prepared to address such opportunities – quickly and efficiently.
