Compact Binoculars for sale
These are high quality compact binoculars, first designed by Nippon Kogaku Company in Japan (later renamed Nikon). The design from the 1920's was produced for many decades, then abandoned, but Nikon put them back in to production recently and sells them for $250 to $300. Several companies made them in Japan and these have been refurbished, cleaned, and the images aligned for proper visual optics, at a fraction of the price of a new pair of Nikon Mikron binoculars.

This is just a fun page about our dog Belle, and friends. Sort of a Dog Blog. She is no match for Marley in the recent hit novel, but still a lot of fun. April 2010 added a couple of photos of her litter of mutt puppies, and their times with us.

Amp Project Page This is a
page documenting a project I got started on after I restored a
Sparton 1568 console radio with a 2A3 power amplifier. That
Sparton sounded to nice that I looked around and decided to
build an integrated stereo 2A3 single ended triode tube
amplifier. This is a long project, took about 4 months just to
get a final version of the schematic and collect the basic
parts. Just finished the amp and will get the pictures up soon.

page on fermenting your own home brewed root beer.

Germanium Diode Assortment
Five germanium signal diodes including a 1N-60, and 4 general purpose germanium diodes. All 5 for $5 postpaid within the US. These are great for building crystal radio projects. The 1N60 is particularly sensitive to small signals.
Mounted Argentiferous Galena Crystals
These are excellent quality galena detector crystals mounted in Wood's Metal for a 7/16 inch diameter mounted crystal. Made with fine crystalline argentiferous galena that is the best "rock" I have ever used. 3 for $12 includes shipping within the US by first class for crystals only. If you have bought crystals from other sources you may be disappointed with their performance. Not these! They work great and 100% of buyers have been thrilled with the results.
