NERF Blaster: Air Restriction Mechanism
(0) | 19/11/2015 | Translate: Bill reveals the engineering design of a NERF blaster, including how it shoots only one dart at a time using a novel air restriction mechanism.
An air gun underwater This is a new invention I created, it is being manufactuered by H2Odyssey and will be available some time in September for around $130 at the store. Here is Underwater footage of two Scuba Divers shooting each other with Bubble Rings. The device is a Torid Pulse, it is a sort of Bubble Gun that attaches to the low pressure port of your scuba tank, just like a back up regulator. It will shoot round Bubble Rings up to about 35'. The device is easy and fun to operate, is low maintenance and does not seem to harm the environment, fish are indeferent and it only uses compressed air. On a typical dive of about 30' deep, you can stay submerged for about 45 minutes and still shoot 300 shots or so with out issues of air exhaustion.- A semi diesel engine starts and jumps in all directions This video illustrates what happends when these two stroke semidiesels run out due to too much oil in the crankcase. With my left hand, I block the injection pump, so from that time the engine run on lube oil only, no diesel at all. I have heard lots of stories about this from decades ago but this is the first time, to my knowledge, that it is captured on video. Luckily we had blocked most of the air intake prior to starting and ended at somewhat over 1000 rpm. Max operating rpm is 425-450. With full air supply, I would guess this engine would reach thousands of rpm and I could only guess what would have happened then...
- Man who had spent 25 years in prison, finally found not guilty Daniel Villegas, now 41, returns to a courtroom for the third time to face murder charges. Some background on his case: the charges Villegas is facing date back to 1993, when Armando “Mando” Lazo and Bobby England were gunned down in El Paso, Texas. Villegas was 16 years old at the time. He then confessed to those shootings, but later claimed he was coerced by an El Paso police officer into a confession. Villegas had a mistrial in 1994 due to a hung jury, then a conviction in his second trial in 1995.

The aircraft had circled Jeddah for several hours and was forced to make two low passes until it was allowed to land on runway 34R at around 22 00 local time.
- Indian students have created a functional Iron Man suit This exoskeleton is the brainchild of final-year student, Vimal Govind Manikandan from the MES College of Engineering.
He says he was inspired by Hollywood movies, especially Avatar’s fictional AMP (Amplified Mobility Platform) suit.
Ditching expensive and complex software programs and sensors, Manikandan says his G2 prototype uses battery-powered pressurized air-chambers that help the giant robot move about and lift up to 150 kilograms. Developed with help from college authorities and students, the G2 uses a pneumatic compressor unit - or pressurized-air chamber system - and a control unit which combine to make the prototype workable.
The team of students designed and built the frame with local support.
Manikandan believes his robot can potentially be used in the military and industrial sectors which require the lifting and moving of heavy materials.
Though not as sleek as similar products on the market, like the recently unveiled range of exoskeleton suits by Panasonic, the G2 has one big advantage.
It cost just US$750 to build the prototype.
- In Tune with Time – Watchmaker Masahiro Kikuno Masahiro Kikuno is a master craftsman who belongs to an exclusive international group of independent watchmakers. These consummate artists create timepieces that reflect their deepest ideals, with no connection to commercial watch manufacturers. Kikuno's creations are deeply influenced by traditional Japanese culture. He's fascinated by a masterpiece called the Myriad Year Clock, which was built by a 19th-century Japanese mechanical genius. Containing over a thousand hand-made parts, the clock is a marvel of complex and precise engineering. Kikuno seeks to transcend that old master's achievement by giving the clock a modern rebirth in the form of an elegant wristwatch. This program documents Kikuno's exacting methods of designing and hand-machining all of the delicate parts needed to create a modern masterpiece.

Potholes are nothing new, but this stretch of road not only looked like it was subject to an air-strike, but I saw for the very first time in my life, an exposed electrical wire coming out of the pothole."

- Primitive Technology: Natural Draft Furnace I built a natural draft furnace to test ideas about how hot a furnace could get without the use of bellows. Natural draft is the flow of air through a furnace due to rising hot air. The hot gasses in the fuel bed are more buoyant than the cold air outside the furnace causing them to rise. Fresh combustion air then enters the base of the furnace to replace the rising combustion gasses, keeping the fuel bed burning. This effect increases with: 1. the average temperature of the fuel bed relative to the outside air and 2. The height of the furnace. Two other important factors are the size of the tuyere (air entry pipe) and lump size of the fuel bed as these effect the resistance to airflow through the furnace. The furnace was tested with wood fuel and some ore was melted but produced no iron. High temperature were indeed produced (probably about 1200 c). These types of furnaces were once used for smelting copper and iron ores in around the world in ancient times, usually using charcoal as a fuel and in some cases wood too.
