I really wanted this to come out square but that hardly ever happens. I will attempt to squeeze it into a square shape in the reduction.
A worker affixed bolts at a joint between segments.
On Saturday, workers replaced third rail near Bryn Mawr on the Red Line Saturday to help ensure continued, reliable power delivery to Red Line trains in the area. The "third rail" (also known as "contact rail") is the electrified rail through which power is delivered to our trains.
One segment at a time, workers removed existing sections of rail and replaced it with heavier-gauge sections, which can provide better conductivity. Each section is seated on insulated third rail chairs, bolted together with adjacent sections and smoothed out at joints. Welders also come out and connect the rail to the power system using jumper cables.
The rail that's been removed will be reused for other important power delivery improvements, later—an efficient and sustainable practice we employ to make the most of the materials at our disposal.
The section replaced on Saturday morning and afternoon was on the Howard-bound Red Line track and measures in at about 1900 feet, or about 580 meters, in length. To put the heft of this work into perspective, the base, steel component of third rail that was installed weighs about 85lbs. for every three feet of rail—this doesn't include the weight of aluminum that's affixed to the rail for added electrical conductivity, bolts, insulators and other components that are a part of delivering power to trains. The total weight of the steel part of the rail moved just on Saturday is upwards of 52 tons.

Management of special forest products is an important component of ecosystem-based resource management at the BLM in Oregon and Washington. Although they are commonly referred to as “minor forest products” restricted to vegetative material, the products impact local economies, cultural heritage, and natural resource education.

As part of the team building component of Term 1 Project Management, students are given a box of dollar store objects and a mission: keep a marble moving along a course for as long a time as possible, with it ending up falling into an egg cup. Armed with plastic necklaces, dominoes, bendy straws, a roll of toilet tissue and other priceless objects, teams compete to create the best design to meet the goal. Upon completion, the teams analyze their designs for strengths and weaknesses and process key team dynamic components — How were design decisions made? How were disagreements resolved? How was leadership determined? Did team members contribute equally to the vision and how did they each fare when it came to implementation?

"The purpose of hip replacement surgery is to remove the two damaged and worn parts of the hip joint – the hip socket, acetabulum, and the ball, femoral head – and replace them with smooth, artificial implants called prostheses, which will help make the hip strong, stable and flexible again".

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.

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.
Active components of the tireflies. The circular structure is a coil spring, which we are seeing end-on. When the structure is bumped, the spring bends until it hits one of the walls around it. When that happens, the circuit turns on and blinks for a little while. A neat trick is to instead force it to blink all day long by making the spring touch the walls all the time.

The laser mounts I designed turned out not to fit - a slight scaling error between the SVG original and illustrator export. Eventually I turned the mounts around and drilled two 12MM holes that fitted the lasers almost exactly.
Some duck tape did the rest - something to recon with in a next iteration
