Default Some Cool "HANDS ON" Web sites

Hi Folks,


Thought I would post some sites I found to be packed with extremely practical information. I apologize in advance if some of the links have already been posted by others.
First up is ' Journey To Forever' that has info on Organic gardening, Biofuels, Solar Ovens, Community Development, Etc. Just check out the column on the left of the page. Heres the link: http://journeytoforever.org/

Next up is 'QRP home builders': http://www.qrp.pops.net/
This site provides infor., instruction and schematics for building Low Power (that is what QRP means, 'lower your power') home brew ham radios and accessories. It emphasizes using common electronic parts, AKA 'popcorn' parts and a type of simple construction known as 'dead bug construction' that avoids tiresome circuit boards with copper tracings. QRP involves operating at 5 watts or less and would seem more likely if and when the power grid were to go down.
A good source for parts that I have found is: http://www.goldmine-elec.com/
also: http://www.digikey.com/ and http://www.danssmallpartsandkits.net/
If your looking for a circuit board already made and it was posted as a project in the past in some electronic magazine you might find it here: http://www.farcircuits.net/

Regarding colloidal silver making, if you go to this web page and scroll midway down you will find a schematic of a circuit that limits the amount of current used when making colloidal silver. The biggest problem in making colloidal silver is as the silver goes into solution the problem of run away current occurs and generates large clumps of silver that are not effective and of any use as they are too heavy and fall out of solution, they are then not in colloidal suspension!
Here is the page: http://www.colloidalsilver.com.au/
here is the actual schematic:

By the way you can get the LM334Z very cheap at electronic goldmine (http://www.goldmine-elec.com/) at $.79 ea, their part number is G22112. Also resistors at $3.50 per hundred. I would suggest 100 ohm and 1,000 ohm. Also get diodes such as a 1N4148 or 1N914.

Finally here is a site that deals with technical books that have long ago lost their copyright restrictions but deal with technology that our grand parents or great grand parents may have used but we might need to revive in the near future.
Lindsey publishing: http://www.lindsaybks.com/ I found their books to be a wealth of information. I have gotten books on making rope, casting aluminum parts and making a old style view camera. Cool.

Default Re: Some Cool "HANDS ON" Web sites

I have not seen them before. I saved your whole post, and I will check them out one by one.

The first two are extremely promising. We are thinking of going into ham radio operation. There is a little bit on it elsewhere on Avalon, not the forum. But this one seems very practical.

Thanks a lot!
