Test Strips for Sale! (pH, Medical control, blue litmus and unknown)

Various testing materials for sale. I found them under my bed, in a bag with some safety goggles(let me know if you want some of them, i have like 8) I have no clue how much this stuff is worth so just shoot me a price and we will work from there.

Dead Lawn--Fix Ph under evergreen trees.

Coniferous trees (pines, etc) acidify soil under em. Lawn doesn't cope wit this too well. Dump your old boxes of baking soda from freezer/fridge under pine tree. It works. Grass grows better. I'd do an -ible, but didn't bother to take pics. If you try it, maybe take before + after pics and post an -ible.

Finding googols without a search engine!

It is not often that you encounter a googol as a "measured" (or inferred) quantity referring to something physical. A preprint out today on arXiv:astro-ph presents a calculation of the total entropy of the observable Universe (in units of Boltzmann's constant, k), coming up with a result Sobs = 3 × 10104 k. The dominant contribution is from supermassive galactic black holes, for which the entropy is proportional to their surface area, which in turn scales like the mass squared.

PH BALANCED NO-RINSE FOAMING SOAP ANYONE??

HI. My mom is bed ridden and we have to give her baths in bed. We have tried several different foaming no-rinse soaps and have found on that works the best: Medline Remedy 4-in-1 Body Cleanser. It is good in so many ways, pH Balanced, Non-allergenic, leaves her skin soft, smells great...nice sort of mango-vanilla smell. Problem is, it's $10 + per bottle, depending on where we get it. Here is the product description: Remedy 4-in-1 Body Cleanser cleanses, moisturizes, provides mild protection against transepidermal water loss (TEWL) and nourishes skin in one step. Helps reduce odor. Optimizes shelf space and nursing time. Ready-to-use, no-rinse foam stays in place to prevent product spills, waste and patient discomfort. One bottle contains over 340 pumps of foam.Harsh soaps and surfactants strip skin of moisture and contribute to TEWL. Remedy 4-in-1 Cleansers have a phospholipid base that binds both water and nutrients to gently clean and condition the skin. Remedy cleansers contain ingredients derived from natural and organic oils that mimic the body's natural lipids. Remedy cleansers can also be used during showers in place of soaps. The phospholipids will gently cleanse the skin without stripping it from its natural oils.Olivamine is a blend of antioxidants, amino acids, vitamins and methylsulfonylmethane (MSM). These ingredients are all known to play a vital role in basic cellular construction and protection. Olivamine contains antioxidants like hydroxytyrosol, the most potent antioxidant known today (derived from olives). It also contains amino acids like L-proline, L-cysteine and glycine - three of the main building blocks of collagen. These components are also treated with photoacoustic resonance to help minimize the tendency for inflammation, and to ensure they can be rapidly accepted by the skin.No-rinse foam for head-to-toe cleansing and conditioning. Indicated for hair, body, perineal and peristomal areas.Remedy is a trademark of Medline Industries, Inc. UPC is: 0 80196 30616 2 CAN ANYONE COME UP WITH A LESS EXPENSIVE, HOME-MADE OPTION TO THIS? Thanks

Arduino based aquaponics controler

Hi guys,  im new to the arduino world but im really enjoying getting to know it. i have a small aquaponics setup and i would like to build a arduino controller so i can see whats going on there. such as water temperature, pump, eventually i want to add automatic feeding PH levels. my water pump is a DC 1000 gal and hour pump, i usually leave it running and i would like to be able to run it on and off as needed also i want to divert the same pump thru DC solenoids to water my beds.  so any help would be greatly appreciated.

What would be the best amplifier for these speakers?

Hi guys, a few time ago I needed a set of speakers for my PC so I brought back to the light two speakers from my old Philips Hi-Fi ( http://imageshack.us/photo/my-images/216/28505497yt5.jpg/ ) and a set of 2 broken PC speakers that I didn't throw away when was time to... So, long story short, I used the PC speakers circuitry to supply my Hi-Fi speakers and plug them to my PC. Now I was thinking if there is any way to give a better supply to these speakers in order to get a better sound. Speakers: FB 545 PH Impedance: 6 ohm Watt: 100 Thanks  :)

First Solar Powered Speedboat

Via The UberReview"It is not too often that we associate solar-powered with anything fast and or furious, but perhaps it is time that we start. The Czeers MK1 is a 10-meter vessel covered in photovoltaic cells that is capable of hitting speeds of up to 30 knots (55.5 km/ph to you non-nautical folks out there). While there are certainly faster boats on the water, those tend to use obscene amounts of fuel. The solar-powered Czeers MK1 is naturally going to be a lot quieter than its gas guzzling cousins, which would make it great for sneaking up over fish (though there is limited space to put them if you catch them. I would like to see a similar model with little bit more space for passengers, even if it did mean sacrificing some speed. Speedboats are so limited in what they are able to do, but if this had a little extra space, it could do so much more."

Jargon ... it's not just for breakfast anymore

Here's the title and abstract of a preprint that was posted to arXiv yesterday. I have no certain idea of what it all mean, and I'm a practicing physicist! I just find the ratio of unintelligible jargon to English really amusing.Monopole and Topological Electron Dynamics in Adiabatic Spintronic and Graphene SystemsAuthors: S. G. Tan, M. B. A. Jalil, Takashi FujitaComments: 21 pagesSubjects: Quantum Physics (quant-ph)A unified theoretical treatment is presented to describe the physics of electron dynamics in semiconductor and graphene systems. Electron spin fast alignment with the Zeeman magnetic field (physical or effective) is treated as a form of adiabatic spin evolution which necessarily generates a monopole in magnetic space. One could transform this monopole into the physical and intuitive topological magnetic fields in the useful momentum (K) or real spaces (R). The physics of electron dynamics related to spin Hall, torque, oscillations and other technologically useful spinor effects can be inferred from the topological magnetic fields in spintronic, graphene and other SU(2) systems.

Drunk Driving Bank

I am looking for ideas or a complete solution to locking up your car keys when getting drunk, but allowing access to the keys the next day to go to work or whatever. The idea is to make an electronic bank of sorts that you would deposit your car keys into and it would be time delayed, so you could not open it till the following day. Another idea is to make a breathalizer that you could make and install in your vehicle, and not have it monitored or have to make monthly payments on it as they are set up now. I know my son has good intentions of not drinking and driving, but we all know when drunk, your intentions are impaired. if people that wanted to drink, yet not drive, a setup like this could save people from driving when impaired even though they normally wouldn't. If someone has an idea on this issue, I would love to hear about it and could help in the construction of this type of device, be it supplying components, to financing the project. Message me here and I can give you my ph number, etc to make getting together easier. Dan

Buy this and make something cool

My place of employment is currently trying to clean out a warehouse full of stuff they don't use, and I've been given permission to have a yard sale! I thought some of it could be used by the Instructables community to craft something amazing. First thing up for grabs is lots of (mostly) steel wire. Price is negotiable. Make me an offer or it gets dumped in the recycle bin in a few weeks. I have lots of different stuff to get rid of some of the more useful stuff might appear here (I got some aluminum squares of various sizes that could go). email garagesale@pittraffic.com or PM here.

AC motor power supply

I have an old Dayton electric motor I pulled out of a lab blower. (I have no idea how old it is, I pulled it out of my grandpa's bottomless basement.) It looks like it still works, but I found it with no wires or anything attached to the terminals. (All of the internal connections look good, however.) So, here's the tricky bit, how do I run power to it? I copied everything off of the label on the motor, and I'll post it on the end. I've got very near to 0$ in the project bank, so the cheapest I can possibly do this the better. I don't need anything nearly as sophisticated as speed control, or anything like that. Here's the info from the label: model: 5K261 HP: 1/3 RPM: 1725 V:`115 A: 5.4 Hz: 60 Time Rating: Cont. Temp. Rise: 48C PH: 1 Frame: 56 Brgs: Sleeve Code: H S.F: 1.35 S.F.A: 6.0 Amb: 40C No.: S60CXCDY-4065 Insul: Class: A Thermally Protected: AUTO I'm not quite sure what I'm going to do with it yet, that depends largely on how well it works.

Chemcial Question for Taxidermy Related Project

I am quite interested in the articulation of the bones of animals. I plan on using small game (squirrels, frogs) to begin with, and I will probably donate them to my Biology teacher, since she loves skeletons.The process of defleshing and whitening the bones of the animal is fairly straight forward - soak the carcass/skeleton in chemical baths and take it out when it's done. The chemicals needed for the process are what's going to be hard for me to obtain.I need a 0.3% solution of sodium carbonate. Sodium bicarb is extremely easy to come by, but I've never seen sodium carbonate. I've heard it is used to raise the pH in pools, so I'm guessing a pool store would carry it. But, would it be possible (practical) to make it? Is there a way, using household chemicals, to produce sodium carbonate? I don't need very much.Secondly, I need a 20% solution of hydrogen peroxide. I only have a 3% bottle. I've heard H2O2 is some pretty dangerous stuff. Again, is it possible for me to buy/make it? Would freeze-purifying it work?Thanks for any help, and if I get this to work out, of course it'll all be turned into an Instructable.

H202 production

Wondering if any one have come across a video showing the steps or know how to do this and how to extract H2O2 form the solution to make hydrogen peroxide like discribed from wikipedia article http://en.wikipedia.org/wiki/Hydrogen_peroxide#Manufacture i know i just cut and pasted to make it easer the history  barium peroxide with nitric acid. An improved version of this process used hydrochloric acid, followed by sulfuric acid to precipitate the barium sulfate byproduct.  Sodium peroxide also makes H2O2 Na2O2 + 2 H2O → 2 NaOH + H2O2 those are hard to come by for DIY and thought maybe this would easier  inorganic processes were used, employing the electrolysis of an aqueous solution of sulfuric acid or acidic ammonium bisulfate (NH4HSO4), followed by hydrolysis of the peroxodisulfate ((SO4)2)2− that is formed. peroxodisulfate commonly referred to as the persulfate ion

Yeast fermentation for composting solution?

I threw some hay off my lawn and some green weecds into a garbage can, some sugar and yeast and formented it to slug beer but the slugs did not like it. It then fermented further to vinegar, and a crust of green "Mold?" covered it. seems to have protected the vinegar from further fermentation. I tried a second bigger batch ( morning glory weeds) with less sugar but after a few days of good fermenting it went rotten and stinky. So there are probably thresholds for sugar content. Would the yeast be a way of adding fertilizer to organic gardens? Yeast can (I think) convert urea and nitrate to protein. Perhaps some green stuff has enough sugar to work without sugar addition. vine prunings? maybe. The first batch, i put bleach in to kill off microbes before I added water and yeast. Perhaps hydrated lime would work instead of bleach and also get the ph good for yeast fermentation. This might be a cheap way of liming your garden. (Here in victoria, hydrated type s lime is cheaper than limestone for garden addition. (But it contains more calcium!) The "yeast tea" or vinegar tea could be used on the garden and the weeds could then be transfered to normal compost or used as mulch. It might be an alternative way of using diseased materials of composting seedy weeds to kill the seeds. Brian

temperature logging with raspberry pi

New here, and to Pi/Python looking to log data from a few different sensors from Atlas Scientific (RTD & PH).  I've gotten really stuck so fare in getting these going and was wondering if anyone here can help me out.  so far I've used this code:  import smbus import time import datetime #SMBus(0) - Raspberry Pi Model A #SMBus(1) - Raspberry Pi Model B bus = smbus.SMBus(1) #I2C address of sensor address = 0x66 def temperature():     rvalue0 = bus.read_word_data(address,0)     rvalue1 = (rvalue0 & 0xff00) >> 8     rvalue2 = rvalue0 & 0x00ff     rvalue = (((rvalue2 * 256) + rvalue1) >> 4 ) *.0625     #print rvalue1, rvalue2     return rvalue print("Temperature Data Logger\n") while True:         #Open Log File     f=open('tempdata.txt','a')     now = datetime.datetime.now()     timestamp = now.strftime("%Y/%m/%d %H:%M")     outvalue = temperature()     outstring = str(timestamp)+"  "+str(outvalue)+" C "+str(outvalue*1.8+32)+" F"+"\n"     print outstring     f.write(outstring)     f.close()     #log temperature every 10 seconds     time.sleep(10) I've got the two sensor boards connected to the raspberry pi 3 mounted via a Whitebox Tentacle T3.   The boards are in i2c mode and i can see them using sudo i2cdetect -y 1 (they show up address 63 and 66)  but when i run this program above I just get a red error light when it reads the temperature.   The log file reports a measurement of 2C and 35.2F which is not correct but the red light on the board tells me that the Pi is trying to connect with it.   Anyone able to help?

Sciences PI Plate

Hi every ones, I'm a young engenner in plant biotechnology. On my free time i try to create an open source plate for the Raspberry pi which has lots of functionality very usefull for science project (Plant growing, Invitro cell, hydroponic control, compotemental study...) I'm really a beginer in electronics, but i read a lot electronic book, looking schematic and see video. This plate have : -8x relay 220V 5A control by a Darlington Array -8x Analog input -4x BNC connector connect to 4 Atlas Scientific Stamp (Ph, EC, DO...) -RTC clock (to be sure of time when data are store on database) -LCD screen 16x2 to facilite the reading without computer -This project will come with backend/frontend distribution Before i order all parts and PCB, i wondering if you be able to check my schematic to validate it and maybe improve it  :P Schematic Image files (2Mo) Fritzing file FZZ I have few question too  : 1/ Can i connect all my ICs and LCD to my external power supply, i read on internet this is better than connect on the 5V from the Raspberry PI? 2/ If i connect all 5V on my external supply how many amps i have to provide (the sum of all amps require by parts)? 3/ Do you know an I2C IC can replace the 74HC4052 to make all the plate in I2C and made it usable by more than a Raspberry PI ? (if it interesting) 4/ Which width is recommand for the wire on my pcb 24 mil (or smaller), and for the 220V Relay the biggest ?? Thanks you for your help, and your website ! Regards Erwan

Looking for ideas for a synesthetic exploration project!

I have a project I'm working on, the purpose of which is to create a kind of synthetic synesthesia by taking the information about different people normally interpreted by one sensory system, and transform the way in which the information is presented, such that it is being interpreted through a different sensory system. The most important thing to me is that there is some kind of legitimate scientific basis for the way in which the information is gathered and then reinterpreted. So, for instance, one iteration of this project that I've done was, using litmus papers, I determined the pH of various people's saliva. I then took photos of each individual and also scanned each strip of litmus paper; I then color tinted each photo with the color from their litmus strip, and thus, one could "see" what that person tasted like. What I'm looking for are ideas for sensory data collection. Or, really, even just data collection in general. I'm an artist by trade, and an amateur scientist by interest and inclination, so figuring out ways in which to reinterpret the data isn't something that I need as much help with. Particularly, I'm really stumped when it comes to measuring anything having to do with smell, and in specific, how to measure a given person's ability to detect smells (for instance, quantifying the extent of someone's hyperosmia). I know olfactometers and electronic noses exist, but have no idea as to how they work or how to get my hands on one w/ an art student budget. ;P I got the idea to ask around here for suggestions after stumbling across this instructable for measuring muscle sounds. Thanks for any help or advice you might be able to provide, and I hope you have a very lovely day! =D

Need help finding easy materials for Pyramid Head (Silent Hill 2/Movie) costume!

I know there are a few topics and instructables on how to make a Pyramid Head costume already, but mine's going to be a bit different. I'm going to sort of be mixing costume styles of the Pyramid Heads from the Silent Hill movie, and the second Silent Hill game where he made his debut. I have past experience with this costume, actually. In fact, it was the first costume I ever made myself. My mom and I originally made the helmet out of posterboard and duck tape, but it didn't hold up so well after a while, plus it had a problem where it would get somewhat lopsided, or if I turned my head, the helmet would stay in place. This is because there was nothing inside the helmet to support my head when I turned it, or to keep it to where it moved and stayed upright with my head. The robes I made out of a bloody labcoat/doctor's coat with ripped off sleeves, and a bloodied cook's apron. draped over it to conceal the buttons. Made it look kind of odd with the layering, but I worked with it. I used a pair of white female dress gloves with it, because they looked alot like his. Anyway, this year I was wanting to revamp the costume, and add in a bit more detail, change the style a little. I was wanting to make his helmet more like the Movieverse's helmet', with the sharper angle, and grating on the sides. But I wanted to keep the apron that he had from the second game, since I don't really have the figure for the really ripped PH from the movie. So I come to you all for help. :) I need suggestions for this.  I'm also working on a bit of a budget, and I'm not at all good at woodworking. So I can't use anything like fiberglass or actual metal, I don't believe. I want it to look good, look pretty authentic and recognizable, something people could come up to in conventions and say " Dude, that's awesome", but with easy to find and work with materials. I've never sewn in my life, either, so that's out. My first one I'd like is for his helmet. I already have a decent idea of how to make it. This time I'll probably be working with super glue instead of duck tape this year. Duck tape's a miracle tool, but there's only so far it can go in certain rare situations. Something like a helmet the size of a small child requires a certain amount more work. For the helmet, I'm probably going to be using window mesh like the kind used in certain windows or porch doors for the grating on the sides of the helmet. I got that as a suggestion from another instructable, and after a bit of testing how well I can see through it, I think I can work with it. I think assembling it will be easy. I may tape it together first just to see what it'd look like fully constructed before I glue it, though. My main issue with the helmet will probably be support. I need to be able to turn my head, have it move with me and my body when I'm turning around and navigating certain areas. Does anyone have any suggestions on a way to make it do that? Again, it can't be incredibly expensive. ( About more than 20-25 dollars in this case scenario.) A second bit of help I'd need is his skin. Now, my skin's naturally very pale, but there's the problem of hair. I could try applying some kind of makeup to it, but I imagine it'd smudge badly by the end of the day. If I did that, I'd probably have to wax my arms first. x.x The problem with that is that people would probably want to hug me throughout the day, and I'd be smudging makeup on their clothes. Another idea I had was trying to find a white leotard or something similarly tight-but-thin to use as his skin. I'd be able to dirty it up a bit to make it look like his. Only problem is, I don't know where to get one. There aren't any specialty stores around in a fifteen mile radius that I know of that would sell them, and I can't order online for specific reasons. Does anyone know of any widely known store that would possibly sell leotards, or something similar that I could use to cover my upper and lower body? I know white hose or thin white stockings would work for his legs, but it's the arms and upper body that are bugging me. The last bit of help I'd need is for the Great Knife, his BFS. I think I'll also be making it out of thick posterboard, possibly layered with cardboard as well, painted silver. But I wanted to know if there's a better way. I made a really ramshackle Great Knife before out of posterboard, but in retrospect, it resembled more of a giant paddle. XP It's not much diffirent from a buster sword, but most of the Buster Sword instructables I see here are only with wood. And again, horrible at woodwork.  For the handle of the blade, I was probably going to use the handle of a paintbrush or large cleaver. Anything better you all would suggest? Sorry this is such a long read, but I desperately need the help, and I wanted to get a head start on it before October (the date of the next convention in east TN, I think. And Halloween. ). Thank you in advance to anyone who can offer suggestions. Again, I'm working on a bit of a budget, though. The most I can spend per item is about 20-25 dollars. Shameful as it is to say, I normally get most of my material for costumes from thrift stores, surplus stores, and flea markets. I feel bad that I can't sew or do woodwork like the awesome cosplayers and craftsmen on the site.
