June 17,2015, NY. All scientists stuff and marketing stuff of Creative Diagnostics had a meeting in New York yesterday. The development plan of next season was discussed and Adjuvant was listed one of the key products in this meeting. Research manager and marketing manager of Creative Diagnostics made an agreement through analysis of data of research level and market that more money and time would be devoted to the research of Adjuvant. Most customers are positive about this decision for Creative Diagnostics’ ten-year experience about biotech and they believe that the scientists stuff enable accomplish the plan. In addition, the reason why this decision get extensive support is that it also benefits the research of other products of significance of Adjuvant. An adjuvant is a pharmacological and immunological agent that modifies the effect of other agents. Adjuvants are also crucial components of vaccines. Many currently available inactivated vaccines require Adjuvants to maximize the protective immune responses generated against the antigens of interest. Adjuvants significantly improve vaccine efficacy by modulating, enhancing, or extending the immune response and at the same time reducing the amount of antigen needed. Moreover, initial plan was made and new research facilities and method will be bring in next week. So if you are interested about Adjuvant, pay more attention to our news.

here are some photos of before and after processing with ned hornings plugin using fiji

i have had some very successful and non successful flights and finalized mosaics.

could anyone tell me why some photos respond very well to the plugin and some dont respond well whatsoever and produce little if not no coloration, my input is that the timing of the photos taken are too early and the vines dont have enough foliage on them to output enough infrared light for the camera to pick up

exactly the same camera and setup was used, i cant guarantee that the white balance was the same, or other settings.

thanks

KAP comes first

This week Bre Pettis left Stratasys, two years after Stratasys bought MakerBot, the 3D printer company that he co-founded in 2009. The Bold Machines innovation workshop that Pettis has been running in those two years was spun off and is now his independent company.

Pettis got interested in 3D printing in 2007 after he attended Roboexotica where robots mix cocktails. He studied the RepRap 3D printers so he could use one to print shot glasses at the next Roboexotica. A year later MakerBot was founded.

But (just like me) before Pettis got involved in 3D printing, he tried kite aerial photography. I think KAP always leads to good things. This video is from July, 2006.

If Pettis had thought to combine KAP and 3D printing, there would be no need for the KAPtery.

Booster hardware improves the usable WheeStat voltage range.

$

The problem:

The WheeStat hardware does not provide sufficient voltage to the Counter electrode (sometimes called the Auxiliary electrode) to push the working electrode to its intended limits (+/- 1.65 volts). This can be seen in the ASV scans of Pb2+ containing solutions, below. In this figure, the initial voltage is set in the GUI at -800 mV, but the data does not go negative of -700 mV. Setting the initial voltage to a more negative value will not improve things. For this experiment, -700 is as far negative as you are going to get.

Pb2_ASV.jpg

What causes this travesty?

The problem is that the voltage at the working electrode is established by pushing current from the counter electrode and the counter electrode is constrained to voltages between +/- 1.65 volts. If you have the leads from the reference and counter electrodes connected to one side of a resistor and that from the working electrode connected to the other side, then Ohm's law is in effect and driving the counter electrode to -1.65 puts the working electrode at +1.65. When you are working in solution, however, you have something called solution resistance that is very much not governed by Ohm's law and it can take a lot more voltage at the counter electrode to drive the working electrode to where you want it.

So what can be done to improve the useful voltage range?

To get around this problem, we need to get a larger voltage range to the counter electrode. The simple solution is to provide an amplifier and higher voltage source that does that. A simple schematic for such an amplifier is provided below:

boosterCircuit.png

So I built a little amplifier board and hooked it up to a WheeStat and looked at the voltammetry of a Pb containing solution. The initial results, shown in the main figure to this Note, looked really good. The instrument had no trouble pushing voltages to +/- 1.5 volts and the baseline for the experiment was flat and reproducible. So far, so good.

So, what is the down side?

Unfortunately, there are a couple of problems with this simple hardware design. First, I had a lot of trouble reproducing the initial results. Later experiments with this and other similar designs gave a lot of noise in the voltage direction (x-axis on the voltammagrams). This arose from feedback between two amplifiers in the counter electrode circuit. This feedback is like having a microphone too close to a speaker and it set up a sine wave in the voltage signal that should not have been there. While it should be possible to damp down this unwanted signal using a low pass filter, that introduces more complexity into the booster circuit and further limits the time scale of experiments that the resulting instrument can run. The second problem with the circuit arises from putting a +/- 12 volt source into a circuit with electronics that are only rated for 0 to 3.3 volts. While the instrument should not self-destruct as long as the circuit is maintained, it is pretty easy to screw up. Removing an electrode from solution, or having an alligator clip come off) disrupts the circuit and will cause voltage spikes that will kill sensitive parts of the electronics. Right now, I have a bunch of fried electronics littering my work bench.

Summing it up:

In short, the principle of increasing the driving voltage will improve the useful voltage range of the instrument, but further work needs to be done on the hardware. While I would like to have an add-on component that fixes this issue for existing WheeStat hardware, the simplest solution will probably be to redesign the instrument. In the past week, we built a prototype for a next generation WheeStat that looks like it will solve the above problems.

“Your words create the world around you.”Milton Bluehouse, Jr. @RiverRally 2015

I just recently passed my one year mark with Public Lab and in reflecting on the year, I truly believe it’s the community who has taught the most in this time. The reasons why the people of Public Lab do what they do, the drive to make positive changes, sharing for the sake of growing and learning- this is what makes it work. The collaboration and support found in this network is both impressive and empowering.

This is what brought me here. I could ask the infrared group to help me puzzle through an image I can’t seem to interpret and get responses from people who selflessly offer their assistance. A newcomer asks the Public Lab main list if anyone has thought about low cost mercury sensing and sparks a discussion that brings out the power of a large knowledge base. There is something on that incredible knowledge sharing platform the people of Public Lab have built that I’d like to make a bigger space for: “The why.”

I’m lucky in the time I have to ask questions, and the patience people here have shown me in personally telling me their stories. These stories are the passion, they are the truth, and the motivation. Stories are why we do what we do, how and what happened. The stories are the people and the faces behind Public Lab. I want to bring those stories out.

So here, I will ask you, if you can and if you would: share out your stories. Make this your space and let’s bring back the blog.

What I want to do

Continue to explore the Chris Fastie and Don Blair Arduino controlled Saturn V and SkyShield beta with pan and tilt and CHDK for aerial panoramas. I've reported my initial experience and tried some of this myself with a different pan-only rig.

My attempt and results

Flew Delta 9' Levitation with Canon A495 (just in autoexposure mode). Again used Brooks hangups rather than the kite line clips. Addressed prior reported issue with the camera cable coming loose, by using the ubiquitous Alliance latex free orange bands to snug the cable to the SkyShield pins. I just let the SkyShield dangle rather than attach it to the rig with the velcro pads.

Managed to launch by myself, but had help on rig detachment after flight.

Untitled_Panorama3_smlr.jpg

Questions and next steps

Fly and continue to evaluate.

Why I'm interested

As indicated before, integration of simple computing capability into our projects can provide flexibility and versatility and I'd like to learn more about using these small boards. People have expressed interest in making aerial panoramas. Again, Chris and Don fielded this in a few weeks. Kudos to them!

Mapping the Sweetwater Festival in Rolla, British Columbia

On June 13, 2015, I led a balloon mapping workshop at the Sweetwater 905 Arts and Music Festival in the small town of Rolla, BC, located just across the border from Alberta. I was visiting there as part of a larger project I am working on, Mapping the Northern Gateway Pipeline, tentatively titled, The Map is Not the Territory. For that project, I have been traveling around northern British Columbia and Alberta, documenting the communities along the proposed Northern Gateway Pipeline. More information about the project can be found at pipelinemapping.tumblr.com.

Rolla, BC isn't anywhere near the Northern Gateway Pipeline, but I learned about the Festival and saw it as an opportunity to share Public Lab's tools. Rolla, BC is surrounded by agricultural lands and fracking operations. Many of the people I met at the festival work in the oil and gas industry. It is a huge presence up here and a large employer.

The festival has been going on for almost 20 years on a private farm and has a continuous line up of really amazing music, poetry readings, art exhibitions in a barn and a lot more. The organizers were kind enough to schedule in a mapping workshop at the last minute.

My amazing helper, Anton. He essentially made all the images, helping me walk the balloon around the entire property, twice! At different heights.

It was pouring rain and cloudy for the earlier part of the day, but the rain gods gave us a break and the skies cleared up just in time for the workshop. Balloon in the sky.

I don't remember the name of this musician playing in the background but he was really really good! And could do a split while playing his guitar. I was very impressed.

Unfortunately, the balloon popped before I could do a third round of mapping. We tried storing it in a barn, which turned out to be a bad idea. I learn something from every mapping I do and the lesson I came away with from this one is do not store a balloon in a barn filled with all sorts of possible balloon-popping opportunities (splinters, hay, low ceilings, etc.).

We flew the balloon at roughly 700-800 feet on a clear, windless day, between 4-5pm in the afternoon.

The helium was generously supplied by local artist Peter von Tiesenhausen and the Demmitt Community Centre.

Questions and next steps

This mapping workshop is part of my larger ongoing documentation of the northern communities in Alberta and British Columbia that are located along the proposed Enbridge Northern Gateway Pipeline. The town of Rolla, BC is pretty far away from the pipeline route, but the oil and gas industry has a huge presence up here. Many people work in the oil and gas industry, there are signs of fracking operations everywhere.

The purpose of this mapping was to generate interest in Public Lab's tools and start asking questions about the land we live in, what it looks like, and what are the stories about these places where we live.

Solutions to Plastic Pollution

$

Plastic waste is a huge problem that is plaguing our planet. The numbers of the plastic we produce, discard, and of the amounts that end up in landfills and oceans are gargantuan. What does this mean for us? Plastic waste clean takes upon a considerable amount of tax payers money and deducts from the tourist economy as sites become polluted with plastic. This type of material doesn't degrade until somewhere between 500 - 1000 years. As a result there is plenty of it stacking up for animals to accidentally eat and die from.

Solutions: There have been a few scientific approaches to attempt to degrade plastic but they have either not been efficient enough or not researched thoroughly enough. These methods entail chemically degrading with heat and pressure. Some of the processes are thermal depolymerization, pyrolysis, hydrolysis, and more. They involve converting the plastic waste into usable oils and gases. These methods hold some promise but a lot of them are expensive to start, involve highly intensive capital, and do not receive enough funding. Now this leaves us with the prospect of biologically degrading plastic using fungi and bacteria. Mycelium, mushrooms, and fungi are all apart of kingdom that has evolved over billions of years to secret enzymes that can digest materials thought to be non-digestable such as rocks, oil, and toxic metals (such as mercury). You can "train" almost any mushroom to secrete enzymes to digest just about any substance by introducing the substance to it repetitively. This method is low cost, there is an abundance of the plastic eating substance, and it can be grown anywhere.

Here is some scientific literature about the type of plastic-eating fungi:

http://aem.asm.org/content/77/17/6076.full

http://radicalmycology.com/publications/articles/fungi-the-plastics-problem/

Next Steps: There is no question that more trials, lab tests, and research needs to be conducted concerning the latent potential of mushrooms. More labs need to be free to the public so that mycologist (those who study mycology: study of mycellium - molds, fungi, mushrooms), amateurs and professionals a like can make paradigm changing discoveries.

The reason why I wrote this was to look for a lab space and people interested in a cause like this to being conducting research and applying it. Even if these approaches don't appeal to most people, the cause does and we must address it because it is having an unfavorable impact on our environment and will start affecting us directly sooner than we think. I invite any help or feedback that I can get. I am a college entrepreneur student native of New Jersey but will connect with anyone, anywhere.

The next version of the SkyShield autoKAP controller is ready for you to test. There are a few kits available for sale to anyone interested in trying a microcontroller on a kite aerial photography rig and posting a couple of research notes about your experiences. The KAPtery is offering a package with a ready-to-fly SkyShield and a kit to build a Saturn V Rig and Picavet suspension all for $115.
.

SkyShield22-638-15.jpg
The new version of SkyShield has a DIP switch to select the pan/tilt/shoot regime in the field. The package includes a completely assembled and tested SkyShield and Arduino Nano, and should be the last version to say "SKY-SWEEP" on it (#CollectorsItem).
.
The package includes everything (except the camera) you need to build a working motorized pan/tilt KAP rig for systematically taking photos to be stitched into panoramas (see some here). The package requires several hours of assembly, including a tiny bit of soldering, and I am eager to hear about how to modify things to improve the kit building process. All the hardware designs and software are open source, and it would be great to hear if you have been able to incorporate some of this work into your own projects. .

SkyShield22-637-17.jpg
The package includes everything here except the camera. Some assembly required.
.
I will be doing field work in early July and will not be able to ship any orders from the KAPtery then. So this week is the last chance in a while to place a KAPtery order for this package or a Redstone Rig Kit or other kits.

Rescue Kites

$

I've spent a couple of weeks investigating a interesting concept that is not a research tool but could be a interesting tool in case things go wrong during the act of gathering data.

Sometimes the quest for environmental data takes us into remote locations or areas with a large number of obstructions that would make conventional signaling techniques somewhat difficult. When going into remote locations to gather data, most people will take multiple types of emergency location devices because Murphy's Law will dictate that a battery will always die when you need it, so multiple backups ranging in technical complexity are typically carried.

The idea of a kite as a signaling device first came to my attention from this website: http://www.survivaloutdoorskills.com/signaling.htm the idea is especially intriguing for Public Lab members due to the great numbers in the community who gather data utilizing kites as platforms. The concept itself basically consists of flying a kite in order to get attention in a emergency situation. The advantages of a kite over other aerial signaling devices such as flares are that a kite will fly as long as the wind permits which could be anywhere from minutes to hours aloft. Kites also pose no risk of starting a forest fire, require no inflation devices or batteries. Disadvantages are lack of wind or too much wind (which too much wind would hinder a balloon in this role as well).

While flying any kite in a remote location would attract attention, there are a number of ideas that can greatly enhance conspicuity. If your kite is large enough you could carry aloft a small radar reflector which also could produce visual shine as it bounces about in the sun's rays. The color of the kite must be such that it distinguishes itself from the background as well as the sky. If you do not wish to modify or buy a certain color of kite you could always develop a tail that is either brightly colored or made out of a reflective material that could be added in an emergency situation in place of the standard kite tail.

While any kite would be better than nothing, I do believe that spar-less kites would be far more reliable but if you already have a Delta or other type of framed kite the reliability of it could be enhanced greatly by carrying spare parts which could also be useful should your kite crash during a KAP session.

While not one of my greatest videos (major sync issues that for the life of me I couldn't get right), I did produce this video below that is quite comprehensive and also provides pertinent links and information that may be helpful to those interested in this concept.

What I want to do

Mail a DIY Formaldehyde Lending Library Kit out to five people, and have them use it successfully.

In that spirit, I've put together a few things: a revised photo card, instructions (this research note, actually), pre-scored Kitagawa 710 tubes, and reformatted temperature correction lookup table.

You can watch me use it in this video:

Instructions

Welcome!

Public Lab's Lending Library has mailed you a DIY Formaldehyde Testing Kit for 7 days. Please only use the number of tests you've paid for. You will find a mailing schedule attached, with your loan period and the number of tests you've paid for. If a test needs to be redone please email mathew@publiclab.org to make sure there is an extra tube available.

Preparing for a test

Tests take 30 minutes and can only be performed between 50-95 degrees Fahrenheit (10-35 degrees Celsius) and when relative humidity is between 5-90%. A thermometer/hygrometer is included in the kit to check these values.

To prepare for a test, please close all windows and doors for 24 hours. This assures consistency between tests.

Testing

Verify the temperature is between 10-35 degrees Celsius, and humidity is between 5-90%.

Place meter in the middle of the room, and plug it in.

Remove Kitagawa tube box, and select an unbroken tube. Write info down on the included test card, as shown below. Tubes serial number is printed just above "JAPAN" on the bottom of the tube. Download card here.

turn the timed relay on (this is the only tricky, prototype-y thing) use a pick or the cap to a pen to switch this tiny hidden switch from right to left. You won't have to do this in the final version.

IMG_20150624_221727.jpg

Record your start time and ress the big red button ONCE. It starts a 30 minute timer. In future versions of the kit you won't be able to reset the timer by hitting the button.

At the end of 30 minutes, finish filling out the photo card. Use the chart below to lookup your temperature-adjusted reading. download the chart

Screen_Shot_2015-06-24_at_11.28.05_PM.png

You will receive an e-mail and text when your return date arrives. Put the next person in line's mailing label on the box, close it up put it out for return mail, or drop in a mailbox or at a post office.

Questions and next steps

are there formaldehyde and other VOCs in my apartment

What I want to do

So, I've been talking about the issue of formaldehyde and other volatile organic compounds (VOCs) in indoor air with my friends.

The picture above shows just some of the household chemicals i use in a given month. Nail polish, glues, paint, etc. That quart of contact cement is almost empty after we spent last Friday evening crafting foam mermaid tentacles. Wow what a headache we got, plus you could smell it on the street outside my building and the neighbors complained. But was it formaldehyde or other VOCs? Was it from the glue or from the foam?

Generally, we are trying to understand where we would be exposed to formaldehyde / other VOCs in our daily life and -- depending on the levels -- whether we can ignore it or need to be concerned. Figuring out that threshold is important.

My attempt and results

I am about to receive a Formaldehyde Test Kit in the mail (YAY!) and i am planning what to measure.

  • Maybe my closet where the chemicals and foam are stored.
  • Maybe my bathroom when I am doing my nails. (It won't be the first Public Lab experiment to happen in my bathroom...anyone remember the thermal flashlight experiment?)
  • Maybe I'll take the test kit with me to a nail salon.
  • Maybe I'll take the test kit to a cheap laminate furniture wholesale store.

Questions and next steps

I would like to know:

  • How much formaldehyde is released from a new set of laminate cabinets in a home?
  • What about from a new carpet?
  • When bringing new things into your home that are known to off-gas, does it take years or days for the VOCs to dissipate?
  • How bad is it to do your nails, or go to a nail salon to have them done? OSHA says there is formaldehyde and also a lot of other chemicals: https://www.osha.gov/SLTC/nailsalons/chemicalhazards.html
  • is our formaldehyde test kit going to be sensitive to these other VOCs also?
