The whole process is broken into 30 parts to make the task manageable to the reader.

Notable Notes 38: Thermal Cooking Intro

Thermal (or Retained Heat) Cooking is a method to slow cook food by leaving it hot in an insulated container and let its own heat slowly work.

Few days ago we were introduced on the concept by the #1760 episode of The Survival Podcast with Cindy Miller as a guest.

The podcast is adequately descriptive itself, but if you are a video guy or gal you can watch Cindy Miller’s class on thermal cooking in her youtube channel.

Notable Notes 37: A Look at AC Inverters for Off-Grid Power

We recently stumbled on 2 articles on Inverters and the way to apply them for off-grid (read that as emergency also) power. They are on the Off-Grid HAM blog, and the wrier definitely knows his thing. Check them out!

Οι Μπαταρίες ΑΑ και ο Ασύρματος σας

Κατά κανόνα υπάρχουν μπαταριοθήκες ΑΑ & ΑΑΑ που αντικαθιστούν την κανονική μπαταρία για τους περισσότερους ασύρματους χειρός. Οπότε είναι καλό να έχουμε μια σαν εφεδρική πηγή ενέργειας, αλλά θα πρέπει να την δοκιμάσουμε εν λειτουργία πρώτα.

Και αυτό γιατί:

1. Το βολτάζ των επαναφορτιζόμενων και των αλκαλικών μπαταριών ΑΑ είναι διαφορετικό και μπορεί ο ασύρματος μας να μη δουλεύει με έναν από τους δύο αυτούς τύπους.

2. Συνήθως οι ασύρματοι χειρός κατεβάζουν ισχύ όταν χρησιμοποιούν τέτοιες μπαταρίες γιατί αυτές δεν έχουν την δύναμη να αντέξουν το φορτίο σε πλήρη ισχύ.

Έτσι λοιπόν πριν λίγες μέρες δοκιμάσαμε το Baofeng UV-5R και το Kenwood TH-F7 μας με διάφορους τύπους μπαταριών ΑΑΑ. Εν συντομία βρήκαμε ότι:

New Batterypack and Custom UV-5R Battery Eliminator

This is a continuation of two other projects the External Battery Pack for our handheld radios and an improvement on the Battery Eliminator we did for the Bao.

The Battery-Pack / Powerbank

This is a smaller size using two 18650 Lithium-ion rechargables to get the same voltage as the original Baofeng battery.

We have an affinity for the 18650 batteries, mainly ebcause they are easy to handle, they lead the battery technology at the moment, can be cross loaded to other devices such as USB powerbanks, and we have a plenty of, since we are into flashlights too.
