#PLF2012 - #FreedomStar (by TheDigitalfolklore)
the PLF announces the launch of “Operation Freedom Star”. The mission of this Op is simple. The Peoples Liberation Front is entering the Hacker Space Race that was initiated with the announcement by the Chaos Computer Club that they intended to launch three communications satellites of their own to help circumvent internet censorship. The PLF states that we are in this race to win, and that WE firmly intend to be the first hackers in space.
Our plan for this involves the purchase of one of the many used communications satellites that are in orbit already, and are beyond their commercial usefulness. Many of these satellites are low on fuel and have other issues related to their age, but are otherwise serviceable and useful for the purpose we intend - which is to provide broadband satellite communications to areas of the world that are in great need. We are currently looking at several possibilities, and whichever satellite we chose - it will be called the “Freedom Star”. The purpose of the Freedom Star Satellite will be to provide broadband internet connections using commercially available downlink hardware
Once we have Freedom Star working, we will shift our focus to building our first custom satellite from scratch. We will use the Amsat program to design and launch our own bird, and also study the open source communications satellites already launched as part of this incredible program for possible uses in circumventing censorship, internet shutdowns - and providing other services to freedom movements around the world.
#DIY #Solar Electric Panel SOLDER FREE connections solar power generation (by GREENPOWERSCIENCE)
This is a good option for anyone wanting to experiment with DIY solar panels but do not want to use hot solder. This works good if you have a good clean connection and you are willing to sacrifice about 5% of the solar cells over all watt output.
You can actually make smaller panels this way increasing the wattage per square meter and saving on glass dimensions. This option works perfectly for joining together broken cells and making artistic designs with solar scraps that really produce power. This option is also perfect for solar model builders as this makes the panel one semi-rigid piece.
Instructables user [msuzuki777] had amassed quite a collection of batteries over the years, but was finding that some of his rechargeable AA and AAA cells seemed to be at the end of their useful life. After reading some information at the Battery University regarding the restoration process for nickel-based batteries, he figured he might as well try building a battery reconditioner of his own.
He worked through several designs that either flat-out did not work, or had issues that limited the number of batteries he could simultaneously recondition. After reading about this rechargeable battery capacity tester we featured a few months back, he was ready to give the project one more try.
It seems that the third try was the charm, because his FET-based design worked quite well. He ended up wiring two FETs to each battery, which are connected via a relay. The batteries get discharged until the voltage drops down to 1V, at which point one FET is turned off, allowing the batteries reach their target voltage of 0.4V more slowly.
Despite the self-proclaimed messy layout of his circuit, [msuzuki777] is quite happy with the results. He has been able to recover several batteries, which is a fantastic alternative to letting them decay in a landfill.
less than $1 a watt DIY MAKE YOUR OWN SOLAR PANEL #DIY (by GREENPOWERSCIENCE)
This is part 1 of a complete panel video. There will be three inexpensive options of panel sealing.
This is part 2 and covers the basics for beginners + The cells I am using are all broken cells I purchased for a discount from Ebay. They were all fully pre-tabbed cells. They are the long tab or fully tabbed NOT the clipped tabs. This panel will cost about $60 completed and requires about 1-3 hours of work + resin embedding cure times which are best applied overnight. Part 3 will detail the embedding process and adding an optional blocking diode. How To Build A Solar Panel.
