Here are the basic parts of the system: at left, a standard 7x21 Bushnell Sportview Compact binocular; at lower right, the front lens, 50mm in diameter and about 150mm focal length; and at upper right, the piece that I made out of 2mm thick ABS plastic sheet to attach the lens to the binocular. The strap that holds the mount onto the binocular is just some adhesive backed Velcro - hook on one piece and loop on the other, each piece just folded back and stuck to itself to attach it (the hook piece had a lot of sticky back side left over, so I just stuck some fabric onto that to cover up the sticky stuff). As I mentioned above, there is a 49mm skylight filter glued into the big round hole in this plate, with its male filter thread facing forward to receive the front lens.
In addition to providing a way to mount the lens to the binocular, the plate also blocks any stray light that would otherwise enter the binocular from around the edges of the front lens (which would not be a good thing for clear viewing).
You can use any positive lens that you can find and fit. The only real limitation is that it must be large enough to get a view through it with both objectives, but you don't need 100% of the objectives to come within the diameter of the lens. A shorter focal length will give you more power but a shorter working distance, while a longer lens will give you more space at the sacrifice of some power. Very short lenses will require increasingly high quality to avoid visible aberrations, and when you get shorter than 100mm or so viewing becomes less comfortable - I think because of a mismatch between the power and the lens separation, you reach a point where your eyes don't want to combine the images if the power is too great. Even a very long lens like 500mm, although it doesn't compute as a magnifier per se, still allows you to focus a 7 - 8 power binocular at a distance of a half meter, with obvious advantages for observing small living (or otherwise potentially dangerous) things.

This was a recent (1985) model with a heavy steel cradle assembly. These are still often copied and sold as inexpensive modern replacement seatposts.
Date code = December 1985

Bargain buy on ebay. Was very dry and looked unused. Took in a lot of saddle dressing to get it looking good again. No name badge on rear, steel and not copper rivets and no tension bolt cover, but otherwise looks the same as the 90 version.
This piece of hardware may not be well known, but the Pratt & Whitney R-1820, on which this critical piece of hardware was used, certainly was.

This old Aveling Barford dump truck is the "gate guard" at a private landfill site in Wellington. Was the modified Ergomatic cab door an original fitment I wonder??
I love the way the colors came out on this one. It's sort of like a cross between terra cotta and maybe southwestern, but with a healthy dose of vintage antique paint layers. I have this one listed, but I might have to rescue it and make something for myself out of it.

Unfinished mechanical room room is right behind the rack. All the wiring is already there. Just need grommets.

A very small section of "Takpekpe (Conference)", by El Anatsui. I love this guy's work; he takes small bits of metal from bottle tops and other trash and makes them into these HUGE, blobby, net-like, sculptural wall hangings.
The E-3A Component is taking part in Red Flag 15-2 at Nellis Air Force Base, Nev., from March 2 -13, 2015.

Serious restoration work started at Statfold at the start of October. This is a view of the engine removed from the chassis, shows the surface deterioration it had suffered.

Paul Component Engineering makes some of the most precise and beautiful components in the world. They've been doing it for 20 years and they'll be doing it for many to come.
Based in Chico CA they're making the dream - pared back, entirely functional pieces which operate exactly as they should every time. It's this attention to craft and performance that has made Paul's work truly iconic.
The Cross Lever is simple and comfortable. It won't ruin the line of a bar and can be used either in-line (routing the cables through drops - useful in CX) or stand-alone. We carry it with a 26.0mm and in black or silver.
In 2015, DOE announced that five of its national laboratories will lead in implementing a new $20 million Small Business Vouchers Pilot, a public-private partnership that will connect clean energy innovators across the country with top-notch scientists, engineers, and world-class facilities. With this federal funding, more than 100 small businesses will receive vouchers so they can access considerable lab expertise and tools that will help them test, validate, and introduce new products, expand their businesses, and grow the clean energy sector.

The brakes were by far the biggest cause for concern, once the loco was disassembled. All the components were heavily worn.

Snapshot from an atomistic molecular dynamics (MD) simulation of polylactide (PLA) and polyhydroxybutyrate (PHB) blend. The full simulation time was over a microsecond.
Both PLA and PHB are thermoplastic polymers, and both biodegradable and biocompatible. Why mixtures? Both the polymers have different strengths and weaknesses. By mixing them, one hopes to create better materials. In the this case, materials with better mechanical properties. To be able to do that, the polymers must be miscible.
The simulations show indeed that PLA and PHB are miscible. More interestingly, however, the simulations show the existence of two glass transitions in the blends: 1) at the scale of a few Kuhn lengths and 2) second transition at a longer time scale. Thus, the miscibility of the blends depends on the length scale.
