DIY BioPrinter

DIY BioPrinter
We started out by messing around with an old inkjet printer that we literally saved from a sidewalk somewhere. There's already plenty of interesting things you can do with an low-end off-the-shelf inkjet printer, but they do have some limitations, which we'll get into in the next Step (or skip straight to Step 3 for how we built our own bioprinter from scratch, that you can see in the first picture above). Undressing the Printer We disassembled an abandoned HP 5150 inkjet printer for use as a bioprinter. There's a little momentary switch that senses whether the cover is open. There's also a momentary switch inside the paper handling mechanism that senses whether paper has been loaded. Once you've got your printer all undressed, and figured out how to activate the cover-closed switch - print something! Cartridges Prep Next task is prying open an ink cartridges, so you can fill them with something more interesting. Alternatively, you can cut off the lid using your favorite power tool.

Korstmos Korstmossen (of lichenen) zijn symbiosevormen van twee of meer verschillende "symbionten" of levensvormen. Één partner is altijd een schimmel, de zogenaamde "mycobiont". Die leeft samen met een "fycobiont", een blauwwier (Cyanobacterie) of een groenwier, of een combinatie van beide. Deze symbionten zijn soms zo sterk verbonden, dat de partners niet zonder elkaar kunnen overleven. Symbiose[bewerken] De schimmel, die de grove vorm van het korstmos bepaalt, omgeeft de algen. De algen hebben ook voordeel van de schimmel: De schimmel houdt water vast, dat afkomstig is uit de lucht (regen en mist), zodat de algen het kunnen gebruiken voor de fotosynthese.De schimmel scheidt zuren uit, dat helpt bij het opnemen van mineralen voor de algen.De schimmel ligt over de algen heen en biedt daarom bescherming tegen intensief zonlicht. Leefwijze[bewerken] Over de geslachtelijke voortplanting van korstmossen is weinig bekend, hoewel de meeste tot de Ascomycota behorende soorten apothecia kunnen vormen.

Microbial cellulose - Wikipedia Microbial cellulose, sometimes called bacterial cellulose, is a form of cellulose that is produced by bacteria. It is widely used in the traditional Filipino dessert Nata de coco. The earliest articles describing microbial cellulose was from 1931,[1] it was subsequently identified as cellulose in 1934.[2] Production[edit] G. xylinus extrudes glycan chains from pores into the growth medium. Differences with plant cellulose[edit] Some advantages of microbial cellulose over plant cellulose include: Finer and more intricate structureNo hemicellulose or lignin to be removedLonger fiber length: much stronger and widerCan be grown to virtually any shape and thicknessCan be produced on a variety of substratesThe formula of the media used and the strain of Acetobacter xylinum will determine the quality of the pellicleMore absorbent per unit volume Disadvantages for commercial use[edit] Some issues that have prevented large-scale commercialization so far include: Functions[edit] Uses[edit] Medical[edit]

Hex Nut LED Flashlight To attach the switch to the nut I used super glue to glue it in. If you do this, be careful that you don't get any glue on the button itself, or you won't be able to press it in anymore. Then I attached a wire to one lead of the switch, which would go to the positive battery terminal. To make sure that the switch stays, in place, I jammed in a small piece of cork (wood or plastic would work just as well). Wednes-DIY: Making Natural Dyes Pin It I have been wanting to experiment with natural dyes for a while now, and with all the great new fall colors that have been popping up on our website (and featured in our monochromatic trend) I decided that it was time. This is such a fun, environmentally friendly project that takes a little time, but very little cash. For today’s DIY I’ll tell you about what natural ingredients you can use to make natural dyes, and what shades of color they will yield. What I got: red cabbage, lemons, oranges, beets, yellow onions, blackberries, blueberries, spinach. For bluish/purple dyes: Blackberries and red cabbage can be used to make bluish/purple dyes. For pinkish/red dyes: Beets and blueberries can make a really lovely dusty rose color. For copper/orange dyes: I never realized what a beautiful color yellow onions can have! For yellow dyes: Orange and lemon peels can be used to make a soft pale yellow dye. For green dyes: Finally, spinach can be used to make a beautiful shade of green. Now what?

Phanerochaete chrysosporium, a crust fungus that can degrade phenolic resin plastics! Tom Volk's Fungus of the Month for February 2007 Tom Volk's Fungus of the Month for February 2007 Please click for the rest of Tom Volk's pages on fungi Yes I know what you're thinking. Last summer Adam Gusse, Paul Miller and I published a paper on the biodegradation of phenolic resin plastics with Phanerochaete chrysosporium. The paper, available here, was published as Gusse, Adam, Paul Miller, and Thomas J. Our paper unleashed a storm of publicity. We were soon contacted by Nature, one of the top scientific journals in the world, who published a story on our work called Fungus eats enduring plastic. We were contacted by the European Commission on the Environment, who put out a press release through Science for Environmental Policy called Fungi may be able to degrade tough plastic. Science in the News, published by American Scientist Magazine, picked up the story and published another called Fungi May Harbor Hankering for Nearly Indestructible Plastics. We even got a little write-up in the New York Times in July 2006.

Geo Data Logger: Arduino+GPS+SD+Accelerometer to log, time-stamp, and geo-tag sensor data UPDATES Oct 17, 2013: I have published a guide on using your Android phone to accomplish a similar task by leveraging your Android device's built in GPS and sensors. Feb 6, 2013: Featured on GeoAwesomeness Nov 24, 2012: Featured on Hackaday Nov 21, 2012: Featured by John Boxall @ Freetronics Nov 20, 2012: Featured on Dangerous Prototypes INTRODUCTION I thought it would be educational to build a prototype that I can take on the road to log, geo-tag, and time-stamp sensor data to be analyzed later with mapping and/or data analysis applications. So I figured why not start with a gadget that can log road conditions. This prototype is a generic sensor logging/geo-tagging gadget which means the accelerometer can be replaced with any other sensor(s) to log and map anything anywhere. This guide is divided into the following sections: CONTACT Hazim Bitar (techbitar) techbitar at gmail dot com

research - ingridnijhoff Day 01 @ De Waag Open Wetlab Amsterdam with Pieter van Bohemen & Maria Boto Ordonez Maria introduced me to the pigmented bacteria Pieter and Maria already made in the Open Wetlab. Then we started to re-plate the bacteria and brewing some new liquid nutrition. Fullscreen We are testing the following strains: Micrococcus luteus (ML DSMZ) from DSMZ color: yellow Rhodococcus coprophilus (RC) from DSMZ color: pink Janthinobacterium lividum (JL) from DSMZ color: blue Xanthomonas campestris (XC) from DSMZ color: yellow Rhizobium etli (RE) from DSMZ color: brown Vogesella indoferra (VI) from Dr. Simon Park color: dark blue Arthrobacter agilis (Aag) from Dr. Simon Park color: pink Chromobacterium violaceum (CV) from Dr. The results after one day : Maria and i are searching for a way to extract the pigment from the plates and for a growing method in liquid nutrition. 23.09.14 GETTING THE CERTIFICATE !!! 26.09.14 MAKING THE INK Finding a way to make the pigments liquid. Test 2: WHAT A NIGHT!

MIT Researchers Create Water-Based Robotic Fabrication Method for Natural Biodegradable 3D Printing Although we have mentioned its benefits so many times in the past, while 3D printing is substantially cutting back on waste within the manufacturing industry, it’s actually creating hundreds of tons of waste annually within the consumer segment of the market. The majority of desktop 3D printers you will find in the homes of individuals rely primarily on thermoplastics, many of which negatively affect the environment in numerous ways. In the long run as the popularity of 3D printers continue to soar, there will be mounting concerns about the piles of discarded thermoplastics being sent to landfills worldwide. Because of these concerns, solutions are already being researched, with more environmentally friendly materials already starting to enter the market. Researchers Laia Mogas-Soldevila and Jorge Duro-Royo at the Mediated Matter Group, led by Associate Prof. Water-based deposition of a fabricated model of a maple seed (top).
