Solar Capitalist DIY Solar Backup 12V Power Battery Bucket

by on Mar.07, 2017, under Application

Backup 12 Volt Power is a viable source to recharge handheld electronics, and even power communications equipment and low voltage backup lighting.

I am a cat lover (as well as a dog lover), and have 4 rescued cats. Seeing the value of the nifty buckets leftover from buying mass quantities of cat litter, I find all kinds of uses for them. That they are “stackable” makes them all the more attractive for storing all sorts of things, and economizing on space. Meanwhile, I dream up other uses, such as – I built my own portable electronic amplified coyote caller (see previous post).

A DIY (do-it-yourself) Solar Backup 12V Power Battery Bucket is another such use.

Certainly not that I invented the mental processes, but thoughts and the visualization that follows sometimes has me stumble upon realizing worthwhile combinations.

An example would be realizing that a hole drilled with a 7/8″ hole saw to facilitate installing one of our Panel / Bulkhead / Surface Mount 2 Pin Connector configurations, allows passage of Our Enhanced Grip & Extended Strain Relief 2 Pin configurations, as well. About $5 for (8) sets of 8-32 fastener hardware, makes for a professional job of connector flange installation.

So, I set out to combine this assembly with these handy cat litter buckets to build a DIY Solar Backup 12V Power Battery Bucket.

These buckets are of a size that easily handles the weight and dimensions of one of many available sealed AGM batteries used in portable solar powered lights, the bucket walls provide the means of mounting connector assemblies, and the bucket also nicely houses the wiring.

At this point I am making up these 2 Pin connector assemblies via solder joints protected with a couple layers of heat shrink tubing. Pending orders, We will move into manufacturing finished product vs assembly by adjoining 2 pigtails resulting in the proper polarity for this application.

A feature I figure will lend to this combination being even more attractive is providing 2 connections for the possibility of both solar battery charging and power use, simultaneously. This is certainly not the optimum use, as it undermines the charge controller’s ability to accurately ascertain and respond to the battery’s condition. But, at times, it may be necessary in meeting immediate needs.

Solar Capitalist LLC is an Authorized Dealer for Deltran and We carry their Solar Power Battery Tender line. These units feature a Deltran charge controller – critical to maintaining optimum battery condition.

We have been using an inexpensive means of supporting Deltran’s 5 Watt, 10 Watt, and 15 Watt Solar Battery Tenders, such that they can be oriented for maximum Sun exposure. Supported on light, inexpensive, plastic saw horses (with the aid of some lengths of 1×2 wood), the setup can be easily carried to a sunny spot, and/or reoriented to be in direct sunlight.

It should be kept in mind that this equipment is “portable”. Thus, it is not meant to be left out in the elements for extended periods of time. Nevertheless, the portability lends to the backup use in emergency situations, such as power outages (also potentially handy for camping, etc.). Clearly, the quick connection to “works in a bucket” aspect lends nicely to portability, as well.

Needless to say, setting up some low voltage lighting, and assemblies for connection to handheld electronics and/or other communication equipment, ahead of time would be another step in the direction of preparedness.

We will be adding these 2 pin connector assemblies to our product line on in the near future.

SAE 2 Pin – 10 AWG w/ Red & Black Polarity

by on Mar.03, 2017, under HD Variations

We’ve added 10 AWG 2 pin 12″, 24″, and 60″ assemblies with red & black leads to our product line.

10 AWG facilitates the desired higher current carrying capacity necessary for some applications.

Clearly, customers/installers prefer color coded polarity for certain applications.

Assemblies are available in both polarities to facilitate junctions with combinations of these 3 assembly lengths.

Based on input gained through surveying customers, these lengths are the most desirable starting point for this line of 2 pin connector assemblies.

As established with our existing product line, we refer to red leading to the protected “female” socket side as a “power side” connector, and red leading to the exposed “male” pin as a “load side” connector, with respect to junctions.

We’ve discussed the logic behind these designations at greater length in previous posts, but in a nutshell – you’d want to install a “power side” connector (with red leading to the protected “female” socket side) on the end of a set of leads connected to a power source such as a battery.

Therefore, if you’re making up an assembly for connection to it, for example coming from a solar charge controller, you’d use a “load side” connector with red leading to the exaposed “male” pin.

SAE 2 Pin Power Side - 10 AWG - 12 inch

SAE 2 Pin Power Side - 10 AWG - 12 inch

SAE 2 Pin Load Side - 10 AWG - 12 inch

SAE 2 Pin Power Side - 10 AWG - 24 inch

SAE 2 Pin Load Side - 10 AWG - 24 inch

SAE 2 Pin Load Side - 10 AWG - 24 inch

SAE 2 Pin Power Side - 10 AWG - 60 inch

SAE 2 Pin Load Side - 10 AWG - 60 inch

We will be adding these assemblies to our product line on in the near future.

These assemblies have an enhanced elongated connector body configuration for greater strain relief and ease in manipulation (coupling & uncoupling).

The features of these enhanced connectors are an improvement over shorter configurations used mostly in past automotive applications.  An example would be the SAE 2 Pole Flat connectors for 12 volt trailer hitch applications manufactured by Hopkins ( Part No. 47965 ).

Our Improved Design Connectors are great for Portable Solar Applications, especially PV on Campers, Motor Homes, Travel Trailers, and Boats, for Camping, Hiking, Hunting, Fishing, as well as, Emergency Preparedness.

Shroud design provides greater water resistance, especially installed with shroud edge down, such that it provides a “drip edge”.

Elongated configuration, enhanced with serrations for better grip is much more easily manipulated (coupled & uncoupled).

Combined with the benefit of greater strain relief, our extended configuration is the High Quality Heavy Duty alternative to the generic configuration.

We manufacture under the name Bohemian Biker LLC, and carry out ecommerce under the name Solar Capitalist LLC.

Overmold 2 Pin Connector Specification

by on Jan.19, 2017, under Compliance

Extended Shroud 2 Pin Solar Connector

Extended Shroud 2 Pin Solar Connector

We are moving further along in Our efforts to address the emerging business needs of our Customers..  Specifically, we have developed a specification for some of our products gaining significant commercial attention.  This specification is yet another component piece of documentation that addresses commercial customer needs, especially the needs of those commercial enterprises doing business with government agencies or in the international marketplace.

Maintaining the paper trail documenting specified requirements having been met is often critical to qualifying as an approved vendor in today’s marketplace.

We are leveraging on years of previous experience in this business, and having developed the necessary detail oriented approach and follow through.

RoHS, REACH, and Conflict Minerals requirements create even greater need for this detail oriented approach.  Maintaining impeccable files providing a document paper trail with continuity is critical.

Upon researching, we found that there is no specification addressing the SAE 2 Pin overmold connector.  SAE (Society of Automotive Engineers) Specification J928 addresses “Electrical Terminals – Pin and Receptacle Type” and SAE J1239 addresses 4, 5, and 8 pin trailer connectors, but there doesn’t seem to be an SAE specification for the 2 pin overmold configuration.

Seems the 2 pin overmold configuration was sort of a spin off developed in the early ’80′s using the spacing from the SAE 4 pin connector addressed by SAE J1239.  So, technically speaking, the 2 pin configuration is not governed by any SAE standard, but they were developed to be compliant with SAE J928 and J1239.

Certainly, the SAE perspective was toward automotive applications, including: trailer hitch/lighting wiring, onboard mechanisms (such as power windows), and battery maintenance.

The use of this connector in portable solar applications has presented some new circumstances, ranging from higher current carrying capacities to harsher environments (resistance to ultraviolet light becoming desirable).  In application to Portable PV, added strain relief is clearly a benefit, both in terms of durability and ease of manipulation.

In fact, it may be appropriate for a designation more accurate to the configuration be applied to this connector, such as “2 pin solar connector”.

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!

Tactical Training Target System Components

by on Oct.07, 2016, under Tactical Training Target System Components

As a result of the use of Our SAE 2 Pin connectors in Tactical Training Target Systems, We have taken special interest in them, and especially in the component equipment. Tactical Training Target System Components would include not only electrical connector assemblies (for example, sae2pin connector assemblies), but linear and rotary actuators, micro controllers, piezo vibration sensors, and polymer targets.

Actively participating in Tactical Training using state of the art Target Systems, as well as participating in the market for components – We believe there will be a spike of interest in designing and assembling automated Target Systems. Upon investigating, we’ve found that the components are not all that sophisticated, and considering the number of shooters there are with pertinent knowledge – its entirely possible and likely there will be DIY (do-it-yourself) activity.

In fact, we’re doing exactly that, and moving up the learning curve. Experimenting with some ideas involving piezo vibration sensors to monitor hits on a polymer target via the deflection of a target support. Also experimenting with connection to an Arduino Micro Controller for controlling a linear or rotary actuator.

We are tapping into supplier recommendations, and working hand in hand to prompt and facilitate discussion and DIY activity. It is our hope to connect with those with an interest, and have an open exchange of ideas, experiences, and lessons learned.

We hope to prompt and facilitate discussion of realistic tactical shooting scenarios, and how they might be created with an automated target system. For example, that polymer targets don’t provide visual or audible feedback, makes for more realistic tactical simulation. Lending to further realism, is a target system arbitrarily setting not only which and how many targets move into view, but also the number of target hits that must be sensed before the target drops from view.

Another topic requiring attention and discussion will be: methods of protecting electronics and mechanical gear from stray bullets. For example, plywood may provide some scenario “prop” value (maybe painted up like brick wall, etc.), and it may provide some structure to which to attach components, but it will not provide protection. The more valuable components are going to need to be strategically placed, or provided “bullet proof” protection. This will certainly add to weight and more complicated set up.

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

Attention Commercial Customers !!!

by on Oct.02, 2016, under USA #1

We’d like to highlight our SAE 2 Pin products being “Made in USA”, in terms of Quality, as well as fulfilling “Buy American”.

Seems this might be of particular interest to commercial customers, especially those attempting to attract business with branches of the government.

We’d also like to highlight Our familiarity, willingness, and ability to assemble/provide, necessary documents. For example, Certificates of Conformance, and Certificates pertinent to chemicals (example: EU requirements around Substances of Very High Concern – SVHC’s).

Experience gained in nuclear power and chemical industries – engineering, procurement, and materials management (especially with respect to electrical equipment), has enhanced our ability to meet these requirements.

We’ve come to recognize the attention of government contractors involved in developing and manufacturing target systems, as well as other applications, about which we know fewer specifics. We have learned that at least some of these applications involve solar power, and probably communication or navigation devices.

Tactical Training, as well as, engineering experience has aided us in our understanding in these areas, especially Target System applications. Similarly, knowledge of Tactical Gear and training & installation experience gained in the Solar Power Industry has also been a benefit.

We actively participate in Crisis Application Group (CAG) tactical training in firearms, medical, survival techniques. Thus, we’re continuing to gain hands on training & experience in cutting edge pertinent applications.

We welcome anyone with interest or questions to email Ray Bowers at: or call or text at 302-562-1706 (We are a Delaware LLC, but currently located in Georgia).

American Quality SAE 2 Pin Connector

by on Oct.02, 2016, under USA #1

We have a customer that has used Our Products in His Application for several years now, and he’s recently undergone some pertinent learning.

Initially, in the interest of economy, He had been purchasing some of the cheaper SAE 2 Pin assemblies (elsewhere), coming from offshore.

As might have been anticipated, the lower quality imported product wasn’t holding up to the constant manipulation – coupling & uncoupling.

These short SAE 2 Pin connectors lacking the enhanced reinforcement of Our American Made line, often succumb to conductor breakage within the insulation at the back of the connector body.

This occurs because with manipulation, the conductors get bent back and forth and work harden – making them brittle and subject to breakage.

Our American Made SAE 2 Pin Connectors have an Extended Body which adds Reinforcement, and therefore “Strain Relief”, thus avoiding that type failure.

The Extended Body of Our American Made SAE 2 Pin Connectors also provides for Enhanced Grip and Ease in Manipulation.

These Features are Especially Appreciated in not only High Use Applications, but Harsh Environments as well.

Consider coupling and uncoupling in Frigid Weather when the materials are not only hard & brittle, but the wearing of gloves may make the Extended Body Much Appreciated.

Beyond the Basic Extended Body SAE 2 Pin Connector We offer with 18 & 16 AWG, We offer an Enhanced Grip Model with 12 AWG.

We also make this Enhanced Grip Model available in a Shrouded Version, which provides Protection over the Junction.

As can be seen, producing and offering SAE 2 Pin Connectors in an Expanded array of Configurations as well as Wire Gauge & Lengths is what We are all about.

It is Our Mission to Provide Ease in Obtaining the SAE 2 Pin Assemblies that Best Meet Our Customer’s Needs & Desires, be it an existing configuration, a variation, or an assembly Engineered to Meet Unique Specifications.

Our Engineering Experience aids Us in understanding and communicating in a Professional Manner, yet with Intention – We Seek Out and Enjoy interaction with Customers Appreciating Our Willingness to Assist in the Development of an Assembly that would meet Specific Needs.

We will Never Forget Those that have extended Patience & Understanding to Us in the Development of Our Niche, and with Intention – We Attend to Passing that Spirit Forward.

Our Expertise developed out of being Educated as an “Hands On” Agricultural Engineer, spending most of career as an Engineer in the Nuclear Power Industry and other heavy Industrial Environments, and then going “small business” in the Battery Maintenance and Portable Solar Industries.

One of Our Delights is coming to Know New Applications We hadn’t even considered – Examples: Fishing Lights, Electronic Game Calls, Tractor Mounted Spray Units, Portable Power Units, and even Tactical Training Target Systems.

We welcome anyone with interest or questions to email Ray Bowers at: or call/text at 302-562-1706 (We are a Delaware LLC, but currently located in Georgia).

2 Way Connector as an Alternate Designation for SAE 2 Pin

by on May.07, 2016, under Terminology

Clearly, there are a large number of people who don’t even know these particular designations.

We have been banking on the “SAE 2 Pin” designation, as we feel this automotive designation is most appropriate.

In the interest of capturing the attention of a greater number of seekers, we are keenly attentive to what words others might use in a search.

Somehow “2 way” doesn’t seem all that descriptive, but nevertheless it seems to have caught on with at least a few manufacturers, suppliers, and seekers.

Furthermore, it seems ironic (at least to US – focused on “Made in USA”) that a product manufactured outside the US should become the most prevalent found via an internet search. The Hopkins Manufacturing product 47965 labeled a “2 Pole Flat” connector assembly is found in the towing or trailer equipment area of many discount automotive stores.

Hopkins 2 Pole Flat 47965

Hopkins Product 47965

In our experience (as discussed in previous posts), we have come upon such phrases as “2 prong”, “2 pole”, “2 conductor”, “flat trailer connector”, “12 volt dc connector” being used, as well.

It’s somewhat puzzling to US that the manufacturers of a product marketed and sold in “automotive” stores would chose designations other than that of SAE (Society of Automotive Engineers). Maybe the SAE has rights to that specific designation, and that precludes use of the designation? It wouldn’t seem so, considering the connector design itself is used and simply labeled with an alternate designation.

Without a doubt, what matters is what gets the seeker to that which he or she seeks.
