Notable Note 5: Katrina Experiences…


Yesterday, leafing through pages of printed material, got us a Katrina “survivor” story.
It is of prepping-conscious man that prepared, made the right decisions and faced the situation head on. Additionally he gives a lot of valuable practical advices in how to prepare and how to act.


On the other hand, today we will be reading this account


Reading through the lines ATM, it is gonna be such a sharp contrast to what we -preppers- are accustomed to!

DIY Handheld Radio External Battery Pack


Here is a battery bank I did for my HT.
 
My hand held radio uses a 7.4Volt Lithium-Ion battery. That means that there are batteries wired in series in the battery pack. So one can duplicate the voltage by connected two stand alone (in this case two 18650) lithium-ion batteries in series.



So this battery pack uses a 18650 battery case like this.
http://www.fasttech.com/products/1286603 
I just had to rewire it for 2series-2parallel.


Important Safety Notice…..
There is a safety issue with the way the batteries are connected in this power bank (2 series – 2 parallel). Lithium Ion batteries in series, are not a good idea without a protection circuit (either a common one like your laptop battery or an individual one in the bottom of each battery).
The theory is that dissimilar batteries put a stress on the weaker one, or the weaker gets its polarity reversed if it gets exhausted and still receives current from the other ones>Then it may ignite.
Monitoring the remaining charge and using matched batteries from the same lot will limit the possibilities of a mishap, but it still your own calling…

Following with construction, I had to work new holes in the place of the existing ones, so I added a new wall to host the plugs. It is made from a DVD case, epoxied on and soon I will be adding supporting structures in the area the original PCB screw points are

Batteries that will be used are four Samsung 2600 (Pink) in the 18650 size. This is a cheap but of good capacity battery. Alternatively one can use the Sanyo 2600 (Red) or the Panasonics NCR18650B (Green).
So with the combined capacity of 2x3400mAh* at the moment (Panasonic is expected to release a 4000mah battery in the near future) one can expect to last him almost 3.5 hours with the mike keyed ON in the 5W high mode!!!
(* Actual capacity is around 3100mAh with a 2A load)

One more pic showing the wiring in more detail.
(he black wire (ground) snakes under the fuse holder and is connected to the RCA plug case. All other wires carry the positive current.
Fuse is a 3A one, since my TH-F7 maxs at 2A.
Then the wires end in two fake batteries respectively that are placed in a Kenwood battery case.
A small notice: the batteries appear bare with no insulating shrink wrap, something dangerous. This is not the case, their orignal was replaced with new clear wrap. It is thecamera flash that made it dissapear!

It is of a good coincidence that this HT does not have an automatic battery detection feature. So I choose the lithium option from the menu and made it think it is powered by the original lithium battery (7.4V, 1550mAh).
Also it does not use 3 contacts for the OEM lithium battery, just two. This is most critical because one cannot know how this would work with the radio was using a 3rd contact to monitor battery state. Being dump proved to be helpful in this case

Addendum:

Days after this construction this was found!
this battery case has a user defined voltage output. So it will suit most of the radios in the market. But it is unknown if it can handle the supllied current steady and for how long, or how reliable its electronics are, but it is by its existence alone tempting!

Update 1/17/15

We finally updated the powerbank with a voltage meter. Lithium-Ion battery voltage directly relates to remaining capacity, so now we have a way to monitor state of chrge.

Preparedness, but… Light?


Note: This is an delayed yet improved version of an earlier article in the Greek language. We are happy that our late-served English speaking readers are getting a better version of the article! Enjoy!

In the following few paragraphs we will approach something that has been troubling us for quite a while. How can one keep Preparedness a small part of his daily routine -and life for that matter. In other words how can a Prepper devote a little of his time only?

It came as a surprise to us seeing preppers -in the pilot episode of Doomsday Preppers- admitting that their whole life after work is devoted in prepping.
Two years later we are involved in prepping even more than then, but we still think that a huge consumption of personal and family time is abnormal. Life is many good things more than preparing for safety and comfort in troubled times.

Yet it is true -and a concern for us- that prepping indeed demands a LOT of time, especially since -and maybe because- prepping is a practical and empirical action. It is not organized and taught as a system but it is (re) discovered through the experience and suggestions of other fellow Preppers. In our eyes this makes it all the more time consuming.

A devoted Prepper must -in just the short span of a few years- acquire skills, practice them and manage to bridge the distance –or gap for some- between the modern life and the more self-sufficient life style of our grandparents and their small communities.
They were born in a more self-reliant society and had their whole life to acquire, hone and transfer skills and methods to the next generation.

On top of these, a modern prepper must also deal with the necessities and unique demands of modern life, especially on novel objects that were unheard of half a generation before.
It is not only not the gardening, husbandry, food preservation and herbal medicine he must learn from scratch, rediscovering traditional skills and forgotten knowledge.
He also has to acquire foreign language skills (if he does not reside in the US), computer and basic internet skills, and delve into communication systems other than the landline and mobile phone. And get a graps of the current complex economic and political situation.

And further on, grasp the basics of sciences and mechanics. To name just two, the prepper has to educate himself on setting an alternate/emergency power system and basic engine and vehicle maintenance. In an age where most Men do not care to learn how to change a tire, relying on phoned-in help to drag them out of what should be considered just an inconvenience.
All these demand lots of time to be used (not spent), especially if one wants to be “ready” in 2 or 3 years since he feels the breath of modern (everyday) dangers on his neck. Crime, Recession, Unemployment, Health Bills, and Mounting Dept to name a few.

But too much time devoted into any endeavor soon results in attrition taken.

Thus we should quest a new approach to Preparedness.

But we admit we have not found anything definite yet.

At the moment we are still striving for a balance between gear and provisions, and skill development. Among them maintaining and expanding our First Aid knowledge, setting up back up power systems -stay tuned for an entertaining new article on this-, expanding on our contingency plans and finally cooking with preps. We seem to have good luck and a breakthrough on the discussed herein issue with the latter.

It is our bread making.
We have chosen not to make our daily bread. It demands time, a lot of power used,  making it uneconomical to make small, frequent batches. Also going through our stores frequently requires even for more time spent on the resupplying process.
Which is what this article is all about.

So we have now chosen to bake occasionally.
It helps that after some fails we are now able to produce something reliably chewable . Thus the rare baking occasions are for rotating our flour stores, honing our technique and trying new recipes.

We can offer one more example, Soap Making. This thing has gotten a cult status for the local prepping and survival crowd. The sort of a fraternity initiation process.
It is charming and to a certain extend a fulfilling accomplishment, but we feel it does not warrant the effort, failures and initial setup cost.
Being objective about it, soap shortages mean that we have ended up with a post-apocalyptic, end-of-technology like scenario that has become Suddenly real.
It pays more –especially in our real daily life- to devote the same amount of time and effort –please remember, this is all what this is about- on gardening.. potatoes. The product is a food, stores well, and is equally tradable.
Yet if you feel MadMax will happen anytime now, go ahead with setting up a fallout shelter first. It is more pressing. You can try soap making latter.

Back on track, it is ironic that conceiving a revised Preparedness method to save time requires some time in itself.
Time to rethink and reform our priorities. Time to study and reevaluate the objectives and necessities of prepping not only on the amount time spent perspective, but on how this time devoted is distributed within the day, week and year.
And calculating the free time, labour and monetary cost of the various preparedness objectives.
For the purpose of achieving the perfect equilibrium between them.

We hope we will be moving forward with this in the short future. Till then we will leave you with some food for thought. A parting shot by Jack Spirco of the Survival Podcast.

Gleaners. Πολεμώντας την Σπατάλη Τροφής


Ζούμε σε μια εποχή που η τροφή έχει αποκτήσει μεγαλύτερη αξία με το να είναι όμορφη. Με συμμετρικές τομάτες και πλαστικές συσκευασίες που κοστίζουν περισσότερο από το περιεχόμενο τους.

Με σουπερμάρκετ που θέλουν ή και αναγκάζονται από την πελατεία τους να πετούν τις μπανάνες που έχουν αρχίσει να μαυρίζουν, χάριν της απαίτησης του πελάτη. Που παρ’ όλο που την πλήρωσε όμορφη θα την φάει μαραγκιασμένη 5 μέρες αργότερα. Αφού έχει ήδη ικανοποιηθεί ότι την αγόρασε από μια Οπωρομπουτίκ.
Με τους επαγγελματίες της εστίασης να πετούν τις περισσευούμενες μερίδες φαγητού γιατί πιστεύουν ότι η δωρεά τους περιορίζει την πελατεία. 

Την ίδια στιγμή η μηχανοποιημένη παραγωγή και συγκομιδή επιβάλει νέα οικονομικά δεδομένα στις καλλιέργειες. Ένα ποσοστό της παραγωγής μένει στο χωράφι ή απορρίπτεται επιτόπου γιατί είναι κακοσχηματισμένο και έξω από τις νόρμες μεγέθους των κανονισμών τυποποίησης. Κάποιες φορές ακόμα και οι εντομολογικές και μυκητολογικές προσβολές είναι επιφανειακές και κοσμετικές (βλέπε Φουζικλάδιο στα μήλα και Κλαδοσπόριο στα πυρηνόκαρπα). Και κάποιες φορές απλά η παραγωγή μπορεί να πάει τόσο χάλια που είναι όντως ασύμφορη η συγκομιδή της ή δεν μπορεί να συγκομιστεί για τεχνικούς λόγους που έχουν να κάνουν με τους περιορισμούς λειτουργίας των συλλεκτικών μηχανών.

Οι Gleaners λοιπόν έρχονται να συλλέξουν όλα αυτά τα προϊόντα εν μέσω οικονομικής κρίσης. Είναι –αν θέλετε- οι ακτιβιστές της σπατάλης της τροφής.
Δεν είναι κάτι καινούργιο, το φαινόμενο εντοπίζεται ακόμα και στους βιβλικούς χρόνους, ενώ έχουμε αρκετές αναφορές σε αυτό τον 18ο και 19ο αιώνα.

Jean-François Millet - Οι Gleaners

Πιστοποιημένες οργανώσεις τους –με ομάδες εθελοντών που προσφέρουν την χειρωνακτική εργασία τους- συλλέγουν την ασυγκόμιστη ή πλεονάζουσα παραγωγή. Ένα ποσοστό το καρπώνονται οι ίδιοι (και ίσως και οι γεωργοί), αλλά πάντοτε το μεγαλύτερο καταλήγει στις τράπεζες τροφίμων.
Το ίδιο κάνουν και με τα αδιάθετα προϊόντα. Τρόφιμα κοντά στην λήξη, ληγμένα αλλά ακόμα κατάλληλα για κατανάλωση, με χτυπημένη ή λάθος συσκευασία ή απούλητο στοκ απο καταστηματα αλλά και βιομηχανιες.

Το όφελος για την τοπική κοινότητα είναι άμεσο. Δεν είναι μόνο η δωρεά των τροφίμων στις τράπεζες αγάπης. Είναι και η διάθεση και άλλων απαραίτητων ειδών σε οικογένειες, αλλά και καινοτόμα προγράμματα ενθάρρυνσης της καλλιέργειας σε κοινοτικούς και ιδιωτικούς λαχανόκηπους.
Μπορείτε αν δείτε λίγα πράγματα για αυτά εδώ:
και εδώ:

Η ανάγκη για εφαρμογή της πρακτικής αυτής στη Ελλάδα της οικονομικής κρίσης που μόνο βαθαίνει ειναι προφανής. Αλλά θα αφήσουμε σε εσάς να φανταστείτε πως θα μπορούσε να εφαρμοστεί στην δική σας περιοχή ή πόλη.

Δεν έχουμε περισσότερα να σας πούμε. Θα αφήσουμε να μιλήσουν για την δράση αυτή μερικά διαλεγμένα βίντεο.

The Gleaners and I, το βραβευμένο ντοκυμαντέρ με αναφορα στο Gleaning στη Γαλλια τον προηγούμενo αιώνα.


 Συγκομιδή μήλων από μια ομάδα gleaners στο Oregon, ΗΠΑ. Πρόκειται για ένα οπωρώνα 40 στρεμάτων, αλλά 60 ετών που δεν μπορεί να δώσει πια "εμπορεύσιμα" μήλα.
 

Η ομάδα των gleaners στο Okanagan του Καναδά παρασκευάζει απο τις σοδειές που συλλέγει αφυδατωμένη σούπα, και την διαθέτει σε ανθρωπιστικές οργανώσεις.
 


Θα θέλαμε να ευχαριστήσουμε την “Cedar” από την ομάδα στο Oregon, που έθεσε στην αντίληψη μας την δράση αυτή, για την παροχή των πρώτων πληροφοριών.
We would like to express our gratitude to “Cedar” from Oregon for bringing Gleaning in our attention and for providing the guiding info on it. Cedar, keep up the good work!
