Japan   Tokyo 2002   circa   4 Colourless transparent and silvered glass/ Plated metal/ Black cap/ Maroon synthetic parts A piece of equipment used at the David Dunlap Observatory at the University of Toronto one of Canada's most important astronomical observatories. The David Dunlap Observatory opened in 1935 as the result of a bequest from the wife of David Dunlap. The telescope was a 74 inch (188 cm) reflector built by Grubb Parsons of Newcastle-upon-Tyne in England. The 74 inch was then the largest telescope in Canada (surpassing the 72 inch telescope of the Dominion Astrophysical Observatory in Victoria) and became the second largest in the world after the 100 inch Hooker Telescope of the Mt. Wilson Observatory outside Los Angeles. DDO's reputation grew and following WWII it began to graduate most of the astronomers produced in Canada with University of Western Ontario far behind. Beginning in the 1960s a number of other astronomy departments were created but UofT/DDO held its place a position it probably still holds. The DDO had a good technical staff which gave them an advantage and with most of the 1940s to early 1970s top astronomers coming from UofT grants from NRC and then ENSERC were almost guaranteed and allowed UofT's top astronomers -- Hogg van den Berg Fernie Bolton Kamper Martin etc. to acquire or build some of the best equipment available in university observatories. For optical observatories only the DAO had technical staff and budgets that surpassed those of DDO. In 2007 citing increasing light pollution the University of Toronto announced plans to sell the Observatory property. In June 2008 it was sold to Corsica Development Inc. a subsidiary of Metrus Development Inc. and the Observatory was closed. In 2009 the Observatory buildings and 80% of the site were designated a cultural heritage landscape. Also in 2009 Corsica and the Royal Astronomical Society of Canada Toronto Centre announced an agreement allowing the RASC to provide public education and outreach programs at the observatory and to operate the 188 cm telescope. A photomultiplier tube is a vacuum tube specifically a phototube that is an extremely sensitive detector of light in the ultraviolet visible and near-infrared ranges of the electromagnetic spectrum. This example would have been used in an astronomical observatory in a photometer an instrument used to measure the brightness of stars galaxies and other astronomical bodies with great accuracy. An example of a photomultiplier tube used with one of the several photometers in this collection which show the development from the simplest (this one which was probably built prior to Fernie's arrival at DDO) with a single PM tube to those with multiple tubes monitoring the sky and star simultaneously to the set used in recent years simultaneously on both the 19 and 24 inch telescopes [2008.0197 and 2008.0198] on the DDO administration building.

There are several wires and cables that are either red green yellow or black in colour. There are several decals affixed to the "Lunabot". These decals vary in colour from white to blue to red. There are two synthetic batteries affixed to the side walls which both have white print. There is a semi-opaque green box and lid also affixed to the outside of the bucket which contains other components and wiring. There is another semi-opaque white box and lid beside the green one which also contains components and wiring. Taken from Reference # 1: The vehicle has been designed by fourth-year students at the Laurentian University Bharti School of Engineering. The school specializes in innovations in mining technologies. The all-male team included: Samuel Carri√®re Patrick Chartrand St√©phane Chiasson Myles Chisholm Drew Dewit Gregory Lakanen Jeffrey Pagnutti and Jean-Sebastien Sonier who were advised by faculty members Dr. Markus Timusk and Gregory Dalton. The team had a budget of $10 000 and cooperated with the Innovation and Development Department at Northern Centre for Advanced Technology. NORCAT is a private non-profit organization created to support young innovative entrepreneurs in the Sudbury area. Located in Sudbury it is closely associated with mining sector and operates an experimental training mine. The Bharti team also collaborated with the Canadian Space Agency and NASA¬ís In-Situ Resources Utilization Program. The Centre for Excellence in Mining Innovation provided some funding. Vehicle designed to excavate collect and deposit a maximum amount of lunar simulant in 15 min. to prove possibility of extraction on the Moon. Taken from Reference # 1: At this moment the conversation on mining in space is mostly propelled by the planetary science community in the United States and in Canada with limited participation from other countries such as India and China. The discussion is led by the Space Resources Roundtable (SRR) a group closely associated with space sciences which is looking to establish links with the natural resources sector and entrepreneurs interested in developing space resources. The SRR organizes an annual Planetary and Terrestrial Mining Sciences Symposium to promote closer relationship between the space and mining industries. The response form the mining sector is not overly enthusiastic. The methodological approaches to space exploration and natural resources exploration are fundamentally different. While space science is highly theoretical mining is based on empirical tangible and material evidence always understood in the commercial\market forces context. Mining industries carefully monitor technological developments and await a sound business case but are not making any substantial commitments to mining in space. NASA together with a couple of space exploration companies such as Moon Express and Shackleton Energy is at the forefront of the technological experimentation on mining in space. This vehicle has been a winning entry in the 2011 NASA competition to design a remote controlled or autonomous excavator called a Lunabot that can collect and deposit a maximum amount of lunar simulant within 15 minutes. The vehicle was designed according to a strict set of criteria provided by NASA such as size (1.5mx0.75cmx2m) mass (<80kg) and tele-robotic control on one channel network. The vehicle had to preserve physical properties of the stimulant with no contamination. The Laurentian University students used Advanced Modeling Technique to design the vehicle and had to calculate various forces that would affect the operation in the lunar context. They had to estimate driving conditions and come up with softwar… Mining and Metallurgy Mineral exploration   Mining and Metallurgy Mineral extraction   Space Technology Miscellaneous   metal;synthetic 240 80 164   170.0 lbs   http://source.techno-science.ca/artifacts-artefacts/images/2014.0031.001.aa.cs.png http://source.techno-science.ca/artifacts-artefacts/images/2014.0031.001.aa.cs.thumb.png

Replicator Dual extrusion 12614 MakerBot Industries United States of America New york Brooklyn 2012       22 Light coloured wood board with black synthetic components such as tubing and cables. Black metal screws with silver nuts. Polished silver metal components. Front of printer has a synthetic rectangular digital screen and a rubber square "M" button with 4 way arrows. Platform is made of a polished metal and rests on a reddish synthetic board. On right side panel of printer is a slot for an SD card. Printer sits on 4 rubber feet. Black synthetic power toggle on back of printer along with peripheral plug in and power plug in. Three dimensional (3D) printers are increasingly used for rapid prototyping and short production runs. Used to produce three dimensional objects from a digital model. Three dimensional printers make objects through additive processes whereby successive layers of material are laid down to produce the desired shape. This distinguishes them from devices that employ subtractive processes where material is removed to essentially sculpt the finished product. In conventional manufacturing subtractive processes are commonly associated with machine tools many of which operate automatically from physical templates or digital instructions. Digitally controlled additive manufacturing may be said to have originated with the Jacquard loom in which punched cards control the arrangement of threads into the final pattern. Moulding machines are a common example of an additive device that uses an analogue model (the pattern and mould) to control the fabrication process. In 3D printing the model is a digital ¬ìblueprint¬î produced using computer aided design (CAD) or animation modelling software. Three dimensional printers were first developed in the late 1970s. A number of techniques have been employed including extrusion deposition granular materials binding (laser sintering) and photopolymerization (stereolithography). Before the turn of the century devices were large expensive and lacking in versatility. Their use was largely confined to industry. In 1995 MIT graduate students Jim Bredt and Tim Anderson modified an inkjet printer to extrude a binding solution onto a bed of polymer powder coining the term ¬ì3D printing¬î and winning a patent on their design. In 2005-2006 two open-source projects associated with universities were established that stimulated the spread of low-cost 3D printing into the do-it-yourself or ¬ìmaker ¬î market. Established at Cornell University Fab@Home released its first device using a multi-syringe deposition system in 2006.
