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.

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.
Sliding Seat frame components - made from pine. For those looking for a darker look, it is recommended to stain prior to varnishing.
Kavalcare Solar System for Jhpiego Mid-Wife Clinic Dec8, 2014
Every year, 12,000 women in Pakistan die of birth complications. The Maternal, Newborn and Child Health (MNCH) Services Component, implemented by MCHIP/Jhpiego, aims at preventing maternal, newborn, and child deaths by ensuring skilled birth attendance (SBA) through a total market approach, empowered community, timely referral of obstetric and neonatal complications to an emergency obstetric and newborn care (EmONC) facility, and improved access to child care.
Lack of electricity in remote areas is a major issue that often leads to obstetric complications and newborn deaths. Refrigerated storage is vital for the effectiveness of life saving drugs and vaccines. Ice boxes are used in remot areas of this purpose but it is an ineffective method especially when easy availability of ice is a problem. To overcome these issues, Lodhie Foundation in association with Maternal and Child Health Integrated Program/JHPIEGO, extended its Kavalcare program and provided a Solar Powered System to a remote clinic located at village Haji Usman Jhakro near Makli, District Thatta. System provides sufficient power to operate a small refrigerator, a fan and 3 lamps 24 hours a day and 7 days a week. It was designed, manufactured and installed by Shaan Technologies private Limited Karachi. After installation of Solar System in August 2014, this small remote clinic is serving a community of 10,000 plus persons who lives in village Haji Usman and surrounding areas. On an average 10 patients visits this clinic each day. Clinic also provides up to 15 birth attendance and new born care in a month.

Challenger 2 (CR2) is the British Army's main battle tank. CR2 is based on the Challenger 1 tank, which served with distinction on operations in the Gulf War and the Balkans.
Only five percent of Challenger 2 components are interchangeable with its predecessor, which has had more than 150 major modifications including a completely new turret, L30 CHARM 120mm gun and second generation Chobham armour.
Challenger 2's thermal observation and gunnery displays a magnified image for the commander and gunner. The commander has a gyro-stabilised fully panoramic sight with laser range finder and thermal imager.
The gunner is equipped with a gyro-stabilised primary sight with a laser range finder and coaxially mounted auxiliary sight. The driver's position has an image-intensifying day and night periscope, and the loader has a day sight.
The Challenger 2 is equipped with a 120-millimetre (4.7 in) 55-calibre long L30A1 tank gun, the successor to the L11 gun used on the Chieftain and Challenger 1. Uniquely among NATO main battle tank armament, the L30A1 is rifled, because the British Army continues to place a premium on the use of High-explosive squash head (HESH) rounds in addition to armour-piercing fin-stabilised discarding-sabot rounds. The Challenger 2 is also armed with a L94A1 EX-34 7.62 mm chain gun and a 7.62 mm L37A2 (GPMG) machine gun. Fifty eightmain armament rounds and 4,200 rounds of 7.62 mm ammunition are carried.
The Challenger 2 is considered to be one of the best protected tanks in the world. The turret and hull are protected with second generation Chobham armour (also known as Dorchester). However, on one occasion, in August 2006, during the post-invasion stage of the Iraq War 2003 an RPG-29 was fired at a Challenger 2 that was climbing over a ramp, the front underside hull armour of the tank which was not augmented with an explosive reactive armour package was damaged, the tank subsequently returned to base under its own power and was quickly repaired and back on duty the following day. As a result, the explosive reactive armour package was replaced with a Dorchester block and the steel underbelly lined with armour as part of the 'Streetfighter' upgrade as a direct response to this incident. To date, the only time the tank has ever been seriously damaged during operations, was by another Challenger 2 in a 'blue on blue' (friendly fire) incident.
It has seen operational service in Bosnia, Kosovo and Iraq.

Some great new components using a similar technique I learned from Stacy Louise. I changed up the recipe a bit for my own look.
The main component of CT/X-ray Contrast Media is iodine. The Iodinated Contrast Media is a colorless, transparent, slightly viscous liquid. At present, the CT contrast agents can be mainly divided into ionic and non-ionic, according to the osmotic pressure can be divided into hypertonic, isotonic and hypotonic. Currently, non-ionic, isotonic or hypotonic Contrast Media are used clinically. When the CT contrast medium is injected, 97% of the contrast media can be directly excreted from the kidneys within 1 day.
Reasonable Use of Iodinated Contrast Agents
Evaluate patient benefits/risks before use
History of allergies: Patients who have previously experienced moderate to severe anaphylactoid reactions to iodinated contrast agents or patients with a history of allergies requiring treatment are at an increased risk of having an allergic reaction to CT dye.
Kidney function: iodinated contrast agents can cause acute kidney injury, and patients should be evaluated for related risks before the surgery.
Combination medication: drugs that may increase the risk of adverse reactions to iodinated contrast agents: neuroleptics and antidepressants, interleukin-2, beta-blockers, metformin.
Situations where iodinated contrast agents should be used with caution: lung and heart diseases, catecholamine secreting tumours, pregnant and lactating women, myeloma and macroglobulinemia, myasthenia gravis, homocystinuria.
Contraindication: uncured patients with hyperthyroidism.
Dose limit for iodinated contrast agents
On the premise of satisfying imaging/diagnosis, the minimum dose of iodinated contrast agents should be used.
For low-risk patients, the total dose of types of contrast agents had better be controlled within 300 ~ 400 ml.
Maximum dose of iodinated radiocontrast dye
Method I *: 5 ml × body weight (kg)/serum creatinine (mg/dl) (not more than 300 ml) [refer to Cigarroa calculation formula]
Method II: 3.7 times creatinine clearance [according to 2011 ACCF/AHAUA/NSTEMI Treatment Guidelines]
For those with severe renal insufficiency, try to choose an imaging method that does not require iodine-based contrast agents or a non-imaging method that can provide sufficient diagnostic information.
Avoid repeated use of the diagnostic dose of an iodinated contrast agent in a short period of time. If repeated use is indeed necessary, it is recommended that the interval between two MRI contrast agent applications be ≥14 days.
Other precautions for the use of iodinated contrast agents
Preheating: Before using an iodinated contrast agent, it is recommended to heat the contrast agent to 37 °C and place it in a thermostat.
Hydration: It is recommended to hydrate patients within 6 to 12 hours before using an iodinated contrast agent to within 24 hours after use. Hydration method: Intra-arterial drug users are advised to receive intravenous rehydration and oral rehydration concomitantly, and oral rehydration is recommended for intravenous drug users.
Stay and observation: After the injection of the iodine-based contrast media, the patient needs to stay and be observed for 30 minutes before leaving the examination room.
Establish an emergency channel: Establish an emergency rapid support mechanism for the rescue of adverse reactions caused by iodinated contrast agents with the emergency room or other clinical related departments to ensure that after an adverse reaction occurs, clinicians can promptly rush to the rescue scene for rescue if necessary.
Prevention and Management of Vascular Extravasation of Iodinated Contrast Agents
Prevention
Choose appropriate blood vessels for venipuncture and operate carefully; when using a high-pressure syringe, choose a puncture needle and catheter that match the injection flow rate; properly fix the puncture needle; communicate with the patient and get cooperation.
Management
Mild extravasation: Most injuries are minor and need no treatment. However, the patient should be instructed to keep observing. If the extravasation worsens, the patient should seek medical attention in time. For individuals with significant pain, common cold and hydropathic compresses can be given locally.
Moderate and severe extravasation: â‘ raise the affected limb to promote blood return. â‘¡ Use 50% magnesium sulfate moisturizing cold compress in the beginning, and after 24-hours change to magnesium sulfate moisturizing hot compress, or use mucopolysaccharide ointment for topical application, or use 0.05% dexamethasone for local hydropathic compress. â‘¢ Those with severe contrast agent extravasation should be given oral dexamethasone 5 mg/time tid for 3 consecutive days on the basis of topical drug use. â‘£ If necessary, consult a clinician for medication.
The brakes were by far the biggest cause for concern, once the loco was disassembled. All the components were heavily worn.

Concrete casting is underway! Here the precision-cast components of Aurora's two new skateparks are prepared for shipment to the construction site. Earlier this year, Spohn Ranch was commissioned to design and build separate skateboarding and BMX facilities for the City of Aurora. We wanted the local riders to have a great deal of pride in their distinct parks, so we cast several of the park’s features with colored concrete and brick texture.
By precision-casting some of the park’s most time-consuming features in our factory-controlled conditions, we are able to avoid weather delays and dramatically reduce our time on site. This state-of-the-art technology also enables us to cast pieces with fully-integrated stainless steel edging, an unparalleled method for increasing the durability of a skatepark.
