There is an RSI article about using an old hard drive as a laser shutter. Unfortunately/fortunately I didn't know about it when I built this one. Well, at least the design is now in the public domain. - Andy Maloney from Bookmarklet
We're using several of these in our lab, too, using the instructions in the same paper you're citing. These things are really great! - Björn Brembs

Scientists Create Real-Life Pac-Man Using Microorganisms - http://gizmodo.com/5735823...
Scientists Create Real-Life Pac-Man Using Microorganisms
"Scientists Create Real-Life Pac-Man Using Microorganisms Scientists have remade Pac-Man using paramecia—microorganisms that you can control with a real joystick while a digital microscope relays images to a computer screen. They call it "Pac-Mecium" and it is not the only game they are playing. The user control the paramecium by just moving the joystick, which is connected to a controller that "controls the polarity of a mild electrical field applied across the fluid chamber, which influences the direction the paramecia move." I wonder how they make Pac-Mecium turn into super-Pac-Mecium. And who is chasing the poor Pac-Mecium, anyway? Evil amoebas? I sure hope so. The biotic game was created by a team lead by Stanford University Bioengineering professor Ingmar Riedel-Kruse, who thinks his games will increase awareness on these organisms and how science is going to affect the behavior of animals, human included. They also created versions of other classic games, like "POND PONG", "Ciliaball" and "Biotic Pinball." In the latter one, the paramecia are in charge of rolling the ball around the board." - Jason Bobe from Bookmarklet

My Instructables showing how to make a DIY objective heater/temperature controller.
Apparently this post is quite popular. I never would have dreamed it but I've gotten over 700 views in one day. I'm flabbergasted since I thought I did a horrible job with it due to what I feel was a lack of pictures in the Instructable. - Andy Maloney from iPhone
That's amazing for one day! And the guy you're commenting with seems very cool as well. - Steve Koch
Can't wait to see how your stir/heat plate write-up takes off too :) - Steve Koch
It would appear that I've some how stirred up open science exposure with this post. It's also apparent that the Instructables community is not afraid to post comments, which is refreshing. - Andy Maloney
It's also apparent that this site may be a great place for people to post materials and methods sections to a community that will be receptive to it. - Andy Maloney

Environmental Scientists, Biologically Active Compounds, and Sustainability: The Vital Role for Small-Scale Science† - Environmental Science & Technology (ACS Publications) - http://pubs.acs.org/doi...
"Toward a Sustainable Monitoring Network for Biologically Active Compounds It is becoming more and more apparent that minute concentrations of biologically active compounds elicit adverse impacts on environmental and human health. Chemical and biological monitoring of these compounds and their effects is expensive and requires a sophisticated expertise in the resource managers. At the same time, there is a wealth of information suggesting that these compounds are widespread and that small-scale scientists and citizen scientists are concerned about these compounds on a local level. Clearly, the dissemination of expensive and highly sophisticated biomonitoring systems to small-scale and citizen scientists is not a sustainable (or even advisible) solution to this burgeoning problem. We therefore propose that an integrated feedback system be developed so that technological advancements can flow from large-scale to small-scale and citizen scientists, while locally generated data can return from these scientists back to university and government laboratories." - Jason Bobe from Bookmarklet

I am making my dissertation writing completely open and based on my open notebook. Here's the first chapter. http://www.openwetware.org/wiki... This is in the rough draft stage but there is more to come.
Another preview of the future of (mainstream) science, imo. Historians and sociologists and philosophers of science, please note and give due credit to such concrete-action early adopters. - Bill Hooker
You kick a ton of ass, Andy! - Steve Koch
Cool, Dude -- will be referring my thesis students to this, especially since I am using a class wiki for some of their work in a pseudo-ONS fashion. In fact, just sent them the link:-). Will also be a good case study for the relationship b/w science and writing which they are discovering is not such a one-to-one kind of thing. - Mickey Schafer

Pranav is amazing. This is the laser shutter he built out of a $10 motorized air freshener dispenser.

Haven't posted in a while but I think some people will be able to use a cheap microscope objective heater that is super easy to build and works fantastically. http://www.openwetware.org/wiki... Just ignore my extraneous notebook stuff included in the page.
You rock - Steve Koch
Not really. The write up is not very in depth and I'm sure it will confuse people. Of which, I apologize in advance for. I just hope someone can use it to build something similar and to use the guys at TeTech. But thanks for the vote of confidence. - Andy Maloney
Feel free to ask questions about the build if anyone wants to build one. - Andy Maloney
Well, I didn't read it all, but with all the great photos, I'm sure people Will be able to replicate it.plus you rock for getting it done so quickly anyway! - Steve Koch from Android
OK, Now I've read the whole page, and I think it is great--all necessary information seems to be there, plus humor throughout. I have a couple comments / questions. - Steve Koch
1) why would a lightpipe help any further? with the objective heated above ambient with your new system, doesn't that buffer the sample from the heating of the microscope body? I'd say your newly flat kinesin speed data demonstrate that is true. So, I wouldn't think lightpipe would help any further. - Steve Koch
(Thank you once again to Erik Schäffer and Diez for explaining this effect to us, BTW!) - Steve Koch
2) I'm skeptical about the remaining initial heating effect being due to photons. But could be wrong. (I guess once you analyze the dim diode data you'll know). But if it is photons, then I don't see how you can solve the problem--whatever your light source, if it's as bright as you like it, then it will heat the sample. - Steve Koch
If it is photons, easiest solution is to just use data >10 minutes for now. - Steve Koch
Maybe it's an effect of the slide changing the thermal gradient on the heated objective? Maybe if you have a blank slide on it ahead of time it would help? In any case, to reiterate, I think you've solved the major problem of long-long time temperature increase! - Steve Koch
Haven't looked at it, but let me guess: It doesn't involve a large trash bag and temperature controlled switch with a hair dryer plugged into it. That was possibly the most ghetto microscope heating setup I've ever seen, but it did seem to work ok for my colleague. - Mr. Gunn
Steve: #1) I see what you are saying and maybe it is #2. I'll just have to look at the data to find out. Not using the Hg lamp is for some reason alluring to me. Maybe because I got a "sunburn" from one and I just don't like them. - Andy Maloney
Mr. Gunn: That sounds like the most awesome thing ever! Although I'm not entirely sure what the garbage bag is used for. - Andy Maloney
Well, the LEDs should last a lot longer and be easier to align, right? - Steve Koch
Oh, the bag was to try to slow down the drying out of the slides. There were live cells in there. - Mr. Gunn

Branching Morphogenesis explores fundamental processes in living systems and their potential application in architecture. The project investigates part-to-whole relationships revealed during the generation of branched structures formed in real-time by interacting lung endothelial cells placed within a 3D matrix environment. The installation materializes five slices in time that capture the force network exerted by interacting vascular cells upon their matrix environment. The time lapses manifest as five vertical, interconnected layers made from over 75,000 cable zip ties. Gallery visitors are invited to walk around and in-between the layers, and immerse themselves within an organic and newly created "Datascape" fusing dynamic cellular change with the body and human occupation, all through the constraints of a ready-made. - Mackenzie Cowell from Bookmarklet
