AVO-19

Manufacturers of penetrating oil like to speak in code. The name WD-40, for example, refers to Water Displacement, 40th formula. It was developed in 1953, by the Rocket Chemical Company to protect the paper-thin outer skin of the balloon tanks on Atlas missiles from rust and corrosion. AV0-19 is another code, referring to Acetone – Vegetable Oil in a ratio of 1 to 9, respectively.

Even though I have been a devoted user of WD-40, I have probably purchased my last container. The reason being is that scientific tests indicate that AVO-19 is a superior product. See: https://www.engineeringforchange.org/how-to-make-penetrating-oil/

No wd-40

The optimal mixture is 10% acetone with 90% vegetable oil. It uses less than 55% of the torque to free rusted bolts as WD-40. It costs about 15% of the price of WD-40. While not as effective as the 1 to 9 ratio, and considerably more expensive, a 30 percent acetone mixture still works better than WD-40.

Engineering students at Drexel University, under the direction of Alex Moseson, conducted comparison tests of vegetable oil mixtures, WD-40 and automatic transmission fluid. Here are some of the results.

Lubricant Price/liter Torque required (Nm)
WD-40 $20.55 68.5
Acetone 30% vegetable oil 70% $5.48 48.4
Acetone 20% vegetable oil 80% $4.52 42.0
Acetone 10% vegetable oil 90% $3.58 36.6

Adam Davies, looked at the overuse of WD-40 in 2010: http://www.popularmechanics.com/cars/how-to/a6064/wd-40-vs-the-world-of-lubricants/

He discovered that WD-40 was second best (or worse) in several important areas. PB Blaster is best at loosening rusted nuts or bolts; Marvel Mystery Oil is best at freeing up rusted compression rings; Finish Line Cross Country is best at lubricating and protecting bicycle chains; while, Permatex White Lithium Grease is best at silencing squeaky door hinges.

Once their workshop is in operation, Unit One will be making its first batch of AVO-19. If you would like some, contact a persona at Unit One.

The Charm of CV1

Meet CV1, the fully automated TeaCoffeeBot. Here is how it works.

A humanoid washes out cup, fills cup with clean water, pours water into CV1’s opening on top, then closes top. Alternative reality, humanoid forgets to close top.

bdr

Then the humanoid pours instant coffee (or puts teabag) into cup.

bty

The humanoid places the cup into the bottom opening of CV1.

bty

Yet another alternative reality, the humanoid puts free Starbucks coffee in space above location of cup. The humanoids assigned to us, haven’t been programmed to do this.

bty

Then humanoid presses button to start water heating and transfer process.

A built in timer is started in humanoid telling it to return to CV1 in three minutes.

Humanoid returns after 30 minutes, picks up coffee cup and delivers lukewarm coffee to intended recipient. Humanoid disappears, then returns to offers intended recipient taste enhancers.

bty

Apart from a few steps performed by a humanoid, the CV1 does everything else!

WD-40

Ginnunga Gap Polytechnic is undoubtedly the best faux institution of higher education that never existed. You can earn a Wonderment Diploma from Ginnunga Gap’s Mechatronics and Robotics program (WD-40)! The program will start in January 2018 and run for two years until December 2019. It is available at the Unit One work space in Ginnunga Gap, otherwise known as Vangshylla.

There will be two participation levels, superficial and exhaustive.

Superficial is designed for people who simply want an overview of the field of mechatronics and robotics.

Exhaustive is at the other extreme, with time devoted to solving problems, theoretical as well as practical.

Even if a Wonderment Diploma isn’t worth the paper it’s printed on, the education on offer will, at the exhaustive level, be as close as possible to a clone of the mechatronics and robotics program offered at the British Columbia Institute of Technology. Given the opportunity to study at BCIT in Burnaby, you will undoubtedly receive a better education there than you will get at Ginnunga Gap. However, if you are unfortunate enough to be stuck in Greater Ginnunga Gap, and lack the funds to pay international tuition fees, the education offered by Ginnunga Gap Polytechnic may be good enough.

The following description of the Mechatronics and Robotics program is a ruthless plagiarism of BCIT’s promotional materials.

WD-40 will provide you with insights into a world where mechanical products contain computers and electronics for monitoring or control. This integration of mechanical and electronic components (mechatronics) makes it possible to design intelligent, reliable, versatile electromechanical systems such as industrial robots, medical devices, aircraft simulators, automated assembly lines, building control systems, and autonomous vehicles.

THE PROGRAM

The Mechatronics and Robotics program at Marmot University focuses on the automation of electromechanical devices and the application of robotic manipulators. You’ll receive hands-on, interdisciplinary training in:

  • Programmable logic control
  • Microcontrollers and electronics
  • Computer Aided Design (CAD)
  • Mechanical Systems
  • Computer and Robot Programming
  • Interfacing Sensors and Activators

The Mechatronics and Robotics program can open many doors. It will provide an advanced education in electromechanical systems and give the benefit of small
class sizes so you can master complex topics by taking advantage of the one-on-one time with instructors. After two years you will earn a wonderment diploma and have the skills to make a good living.

JOB OPPORTUNITIES

Mechatronics and robotics gives many interesting job possibilities. Because it is multidisciplinary, it also prepares for leadership roles in the design and creation of innovative mechatronics products for a variety of applications, including designing
and building automated equipment for the movie industry, medical devices,
production equipment, or submarines.

Here is what we will be working on:

While it is a long time before students will be working on their Mechatronics Project, Unit One is looking for opportunities to make devices capable of monitoring the marine environment in Skarnsund and Børgin, in cooperation with the local chapter of Friends of the Earth.

While Ginnunga Gap Polytechnic has fake application forms, and mock procedures to select students, the best way to come on board is to speak directly to one of the phony personas at Unit One.

PS. Your bogus Wonderment Diploma will be printed in A3 format. Its massive size should intimidate friend and foe alike.

Half-Truths about Healthy Eating

Guest author: Proton Bletchley

Golf courses can be described as green deserts. It is a half-truth. A lot of grass can be grown on them, they are not noted for their ecological diversity, but they aren’t deserts. For the past few days, I have been a regular visitor to a food desert, Cain’s, Your Independent Grocer, in Thompson Country. Again, that sentence contains a lot of half-truths.

independent_01RGB-copy
Franchise operator Jason Cain giving away groceries in a well arranged publicity stunt, 2015-11-10 (photo: http://www.kamloopsthisweek.com/cain-raises-spirits/)

Let’s begin by clearing away some half-truths. Thompson country is Kamloops. Jason Cain is a franchise owner/operator. Your Independent Grocer, is a supermarket chain owned by National Grocers, which is part of Loblaw Companies Limited. So much for independence. See: https://en.wikipedia.org/wiki/Your_Independent_Grocer

The store isn’t really a food desert. One major challenge of visiting this store, despite its enormous size, is finding something edible to eat. My estimate is that about 90% of their food-category products are processed. This means that they contain larger quantities of sugar, salt and additives, than I appreciate. The other 10% of the store contains fairly healthy food. My travelling companion, Daffy Marmot, was impressed with the fresh produce section. The Blue Menu Bleu assortment seemed to meet our culinary tastes.

bty
Healthyish peanut butter

The peanut butter contained 100% peanuts, which means no salt, no sugar, no additives. We enjoyed the crunchy variety, and didn’t mind the separation of the oil, which had to be stirred in. It was all part of the healthy food experience.

bty

One major problem with today’s food stores is the obesity caused by easy access to inappropriate foods. People succumb to temptation. Physically separate people from food, and many of the problems associated with instant gratification will disappear. This too is probably only a half-truth.

Personally, I don’t want to order food. My refrigerator and storage cupboards should be perfectly capably of tracking inventory, and making purchases from an online supplier. My role should only be to make a few supplementary purchases, preferably only within one hour after eating a meal. Don’t worry. Such dictatorial measures will not happen as long as large corporations are profiting from obesity.

One of the objections made to online grocery purchases is an inability to feel produce, things like apples. Yuck, the last thing I want to purchase is an apple that has been touched by 100 different people.

One solution is the use of collaborative robots (cobots) in the food chain. A cobot is “an apparatus and method for direct physical interaction between a person and a general purpose manipulator controlled by a computer.”  http://www.foodqualityandsafety.com/article/robots-help-boost-food-chain-productivity/?singlepage=1&theme=print-friendly

Market leader is the Danish company, Universal Robots, with about a 60% market penetration. Collaborative robot arms belong to an emerging new class of industrial robotics that can operate outside of safety enclosures alongside employees.

Soft Robotics is also making an impression in the market, because their tools can delicately pick and pack food products.

London based, but with its Engineering department in Tallinn, Estonia, Starship Technologies has launched a nine-month pilot program to test out the Starship’s robots on public sidewalks in Redwood City, California. It partnered with food-delivery service Doordash to have its robots transport meals from restaurants in Redwood City’s downtown area. Starship’s robots move just slightly faster than walking speed, about 6 kmh, and they have a range of 3 km. During this testing phase, Starship uses living employees to babysit robots on deliveries. Their ultimate goal is to drive down the costs to less than $2 per delivery. If food deliveries are successful, the company hopes to quickly expand its business to handle grocery trips and delivering parcels.

The Swiss company, TeleRetail, is testing delivery bots in Mountain View. The robots are designed to offer a for-hire service that can be adapted to various tasks. Their business model is based on the Zipcar: anybody can use the robots to run whatever errands they want. They offer a complete logistics platform that enables them to integrate any mode of transportation.

Myrmex is launching an unmanned grocery delivery system using mobile robotic units. It is capable of delivering an online order just seconds after customer arrival at a pick-up point. The system is called CPS for Curbside Pickup System.  Each online order is put into a plastic box which is then placed on a wire frame (pod) with a capacity of 20 boxes. According to Myrimex, more than 50 percent of the online grocery shoppers (young families with children, working people with irregular schedule) are reluctant to choose home delivery because of the challenges in meeting a timeslot. Click & collect gives users advantages in terms of personal time management, and lower costs. http://www.myrmex-inc.com/

Some of the proposed delivery solutions may also turn out to be half truths. Daffy Marmot, for example, feels that many (male) technologists have underestimated the social value of shopping.

Ethan & Ethel 01: Personal Safety Equipment

Welcome to the Unit One Work Space, Ethan & Ethel. Here, everyone is required to wear appropriate clothing and safety equipment.

A lot of information about personal protective clothing and equipment is available from WorkSafeBC: https://www.worksafebc.com/en/law-policy/occupational-health-safety/searchable-ohs-regulation/ohs-regulation/part-08-personal-protective-clothing-and-equipment

Unit One uses the regulations here as guidelines for setting its own policy. Sometimes the rules are even stricter than those the government requires.

Identity Cards and Patches

At Unit One, everyone is issued an identity card. This contains a lot of information that could be needed in acute situations. For example, it lists name, birth date, blood type (if known), current medications, chronic medical conditions, allergies, personal contact information, and contact information in case of an emergency.

While this information is also stored in an encrypted format in the Unit One database, it is important to have this information physically available. Computers don’t always work.

Unit One Billi Sodd
Birthdate: 1950-01-01
Medications: Insulin
Allergies: none
Blood Type: O
Emergency Contact: Ivan Sodd 604-527-4660

The ID card also lists courses you have taken such as first aid and hot work, as well as the machines your are qualified to use.

A Unit One ID patch is available to sew onto work jackets. This includes the Unit One logo, and your name. Its colour indicates your work status: orange – novice, must work under supervision; yellow – qualified, allowed to work without supervision; white – supervisor, allowed to train and supervise other people; blue – member of the board of directors.

Clothing

Personal clothing must be of a type and in a condition which will not expose the worker to any unnecessary or avoidable hazards. First of all, this means that no dresses or skirts are allowed, girls. This is because trousers are safer to work in. Because there is a danger of contact with moving parts of machinery or with electrically energized equipment, clothing must fit closely about the body,

trousers

Neckwear, bracelets, wristwatches, rings or similar articles may not be worn, except for medical alert bracelets. Similarly cranial (that means head) and facial hair must be confined, or worn at a length which will prevent it from being snagged or caught in the work process.

Everyone at Unit One must have suitable gloves to protect hands from abrasion, chemical or other injury.

Flame resistant clothing must be worn when performing hot work, including welding.

Headgear

Unit One provides safety headgear in situations where there is a danger of head injury. Our headgear is colour coded (see above).

headgear
Orange headgear, worn when needed. The orange colour indicates that the person wearing it is a novice who can work only under supervision. (photo: Jula)

Eyewear & face protection

Properly fitting safety eyewear must be worn if one is handling or exposed to materials which are likely to injure or irritate the eyes. In some cases these must be fitted with sideshields.

safety glasses
Eye Protection (photo: Jula)

If there is a risk of face injury, suitable face protection must be worn.

Footwear

Footwear must be of a design, construction, and material appropriate to the protection required. The following factors must be considered: slipping; tripping; uneven terrain; abrasion; ankle protection and foot support; potential for musculoskeletal injury; crushing potential; temperature extremes; corrosive substances; puncture hazards; electrical shock; any other recognizable hazard.

Hearing protection

While we have a supply of ear plugs at Unit One, we encourage people to use ear muffs. These offer less noise-reduction variability among users, are designed so that one size fits most head sizes, are not easily misplaced or lost, and may be worn with minor ear infections. However, they are less portable and heavier than ear plugs, may be less convenient for use with other personal protective equipment, may be less comfortable with hot work, and may interfere with the wearing of safety glasses because wearing glasses breaks the seal between the ear muff and the skin, resulting in decreased hearing protection.

Respirators and face masks

We typically use non-powered, air purifying half facepieces with sorbent cartridges when working with organic solvents. If dust is the issue, we use face masks.

First Aid kit

At the entrance to Unit One there is a first aid kit that contains most items that should be used to treat minor injuries. This kit is never locked, and is accessible to everyone.

This is the first aid kit we have at Unit One. The lock has been disabled so that anyone can access it. (photo: Jula)

Fire extinguishers

Unit One is equipped with two fire extinguishers, suitable for all types of fires. These are located at opposite ends of the workshop.

Ethan & Ethel

It doesn’t happen often, but a new family has moved into Ginnunga Gap. I haven’t seen much of Maw and Paw Maker, but their children, Ethan and Ethel, have already started hanging around the Unit One workshop.

The twins are 15 years old, and just starting out to make things. At Unit One we’re going to be writing some posts that will help them figure out what to do in a workshop. We want to make sure they learn how to “Do It Ourselves” safely.
