It comes with both single and double well slides. The kit has cover slips and a dye Neutral Red. Well slides are used for allowing for live specimens to be monitored and studied. Can be both a dry or an aqueous environment. The aqueous environment can be studied using a drop of water in the well or using a cover slip hanging drop.</div><div style="text-align: justify;"> </div><div style="text-align: justify;"> </div><div style="text-align: justify;"><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEja5HDnqDJq5Fu7ivqORdDlrFYN_c2CU5AzHqkSyOS4cog3sn-bB7-mCu0fbLdml4sHFamXFErjuNMRvJWoWR25hA4PQpmunSKPwPud81EDvlOcvAuBvTBqZST2-FmZ9ooY7EYdwnjfr3HyKxS_j1FUEMbaHXbyFO8N1TIo971g78TF_6JmIaNI5LH-ThCw/s4933/tasco-slide.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="2882" data-original-width="4933" height="187" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEja5HDnqDJq5Fu7ivqORdDlrFYN_c2CU5AzHqkSyOS4cog3sn-bB7-mCu0fbLdml4sHFamXFErjuNMRvJWoWR25hA4PQpmunSKPwPud81EDvlOcvAuBvTBqZST2-FmZ9ooY7EYdwnjfr3HyKxS_j1FUEMbaHXbyFO8N1TIo971g78TF_6JmIaNI5LH-ThCw/s320/tasco-slide.jpg" width="320" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Well Slides<br /></td></tr></tbody></table><br /> </div><div style="text-align: justify;">This Money detector has a light that shines from underneath with a regular white light or can shine a UV light from above.

<span lang="en-US">Dark-field microscopy is when the light from under
the specimen is partially blocked. </span><span lang="en-US">The
light does not pass directly through the sample being studied.
Instead light is reflected off the specimen, making it appear to be
emitting light. </span><span lang="en-US">D</span>ark-field image may
first appear to be a negative of a bright-field image. It works well with
live organisms.</p><p style="line-height: 100%; margin-bottom: 0cm; text-align: justify;">

A simple method is to use a dime placed in the middle of your
microscope filter just below the microscope condenser. I recommend
putting the dime or dime sized stop(made of thin cardboard coloured
black) on a clear piece of plastic to protect the filter from being
scratched. If the clear plastic is rigid enough you can replace it
for the filter all together.

In figure 4 this is a regular image, in figure 5 I use the 8 mm stop.
You can see the difference between the 2. The 8 mm stop shows more
detail than without any stop. With the 15 mm stop it darkens the
field way to much.

This way I can add the same connectors to the hardware and use them with the same power supply. I had an old power adapter from a HP printer laying around. I like to try and use old hardware to build new things. It gives off 19 volts and 7.1 amps. So I started looking for a way to control/vary the power coming from the adapter.So I picked up this DC DC Buck Converter CC CV 50V 5A Power Module.</div><div style="text-align: left;"><br /></div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjoNvbwSB7Rm4XSrWRqF4cozqaCvqz4Q08_VEljRqxc36jO1kxvFgmq1zYoxVWKEZFWbcGxzE4jw2OxRYDng3pA6ItzzHTbNwlT7W_R9kgs3ZN-jmie_KpmabgKTPa0XBwtklCVxtXT8EhN/s2048/pwr-sply.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1806" data-original-width="2048" height="282" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjoNvbwSB7Rm4XSrWRqF4cozqaCvqz4Q08_VEljRqxc36jO1kxvFgmq1zYoxVWKEZFWbcGxzE4jw2OxRYDng3pA6ItzzHTbNwlT7W_R9kgs3ZN-jmie_KpmabgKTPa0XBwtklCVxtXT8EhN/s320/pwr-sply.jpg" width="320" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Components for Power Supply<br /></td></tr></tbody></table><br /><div style="text-align: left;"><br /></div><div style="text-align: left;"><br /></div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhmfIbuWXn_enFgqRjQto0_q73oH0LNlNjHGneqRnytETUgSEgoUDpqRA24BbbOzcIb2Tu7Vpj06IvKMUxoTjtjN1jqw8i2Xf6rocYohcvWLu9-7845XUBSNXNle1bKria_GMO4wXmX_GqI/s2048/pwr-sply2.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1726" data-original-width="2048" height="270" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhmfIbuWXn_enFgqRjQto0_q73oH0LNlNjHGneqRnytETUgSEgoUDpqRA24BbbOzcIb2Tu7Vpj06IvKMUxoTjtjN1jqw8i2Xf6rocYohcvWLu9-7845XUBSNXNle1bKria_GMO4wXmX_GqI/s320/pwr-sply2.jpg" width="320" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Power Supply Working<br /></td></tr></tbody></table><br /><div style="text-align: left;"><br /></div><div style="text-align: left;">Now I don't have to have all these different wall transformers taking up space.

The kit is well priced, I felt shipping was a bit high but that is probably out of their control. It comes with almost everything you need, except the hardware. You do need a incubator (they do supply you with a <a href="https://www.youtube.com/watch?v=LEsv0Qvbczs" target="_blank">video</a> link to build a very simple one ), a hot and a cold water bath. I used an ice bath for my cold bath. They do have an all in one hardware that will do all of this, that you can purchase. Though it is expensive.</span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"> </span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"> </span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5NdPKtYKN2uJ9kKSBHDNSociXqr7bS7Kb-LfkXzUpbH7nFQeCQ8ADPfjoapKXXMvxCF2nbkb82W53tG3JZq_hrLWo7lwsDtiNF3aOy2kX_QsU5k1hNlHZYrYfEDbNtQwU3EFFYjPVuvCo/s2048/Amino02.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1428" data-original-width="2048" height="223" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5NdPKtYKN2uJ9kKSBHDNSociXqr7bS7Kb-LfkXzUpbH7nFQeCQ8ADPfjoapKXXMvxCF2nbkb82W53tG3JZq_hrLWo7lwsDtiNF3aOy2kX_QsU5k1hNlHZYrYfEDbNtQwU3EFFYjPVuvCo/s320/Amino02.jpg" width="320" /></a></div></span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"></span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"></span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"></span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"></span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"><br /> </span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;"> </span></span></div><div style="text-align: justify;"><span style="color: #2b00fe;"><span style="color: black;">They made this kit to be as simple and easy to use as possible, even a beginner can do it.

The power connectors are labelled with 'M' for motor output and 'P' for power input. Using these female connectors I am now able to connect different power adapters(3v - 12v).<br /><br />The power connectors(found at an electronics surplus store) are also a great find. With these I can create different connectors and adapters. People are always throwing unused power adapters at me so now I can use them no matter what end they have. Wires are screwed in at one end of the connector. Where the wires connect it is labeled with either '+' or '-'. So if you find any get some. <br /></span></span></div>Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com0tag:blogger.com,1999:blog-2263348972745615973.post-79799655291234738842021-01-03T19:24:00.001-05:002021-01-03T19:32:38.577-05:00<h1 style="text-align: left;"> <span style="color: #ffa400;">Second-Hand Store Finds</span></h1><div style="text-align: justify;">Second-hand stores can be a great place to find lab equipment and science kits.

As well as discussing older books I will be looking at newer books to. I just received this book from Amazon. It is a very interesting book. As the title states it takes you from beginning basics to the understanding of bio-engineering. There are at least 9 lab exercises to do. From DNA extraction to manually turning on genes.<br /><br />It has a section called "Setting up your Genetic Engineering Hero Space". Covers bio-safety and governmental regulations. The book has sections giving you the background information of what is happening and why.<br /><br />Other than the first exercise, DNA extraction, the other exercises require different kits from the supplier of the book. This can get costly but each kit can be purchased separately, which may help in keeping the costs down. It seems the kits have everything you need to do the experiments easily. The hardware is extra - incubator, water bath, etc.<br /><br />It also requires a lab hardware kit, called, "The DNA Playground Minilab". It incubates, cools and heat shocks the material. This can be costly. But if you follow this blog most of the hardware needed you can build yourself. <br /><br />I will see if I can get some of the lab exercise kits and try them out.

This is one book that I found at my library when I was younger. It was one of a handful of books that taught me science. I would take it out as much as I was allowed to. I read and reread it over and over again. I created many of the projects and did many of the experiments that you find in the question sections. <br /><br />I was already building my lab from what ever I could find and re-purpose for use at home. So I was so excited when I found this book. I believe I really wore out this book. It was still on the library shelves until around 8 or so years ago. One day I went to find it and it was no longer there. I did end up finding a used copy later on so I purchased it for my own library.<br /><br />It is broken up into 3 sections: Chemistry, Physics and Biology. Physics was broken up into 6 other sections: Astronomy and Light, Atomic Energy, Electricity and Magnetism, Forces, Measurement and Motion, Geology and Meteorology.</div>

In figure 2, I use a 3D printed slit holder and then mount 2 single edge razor blades which are adjustable. With the other 3D printed parts I hold the slit mechanism in place within the spectrometer. This allows for removal of the slit so it can be adjusted. In Figure 3 you can see the unit put together.</div>

And in figure 4 you see allthe components put together with the sample and slit holder, LED source, diffraction grading and web cam all in one box.<br /><br />This is all put together in a wooden box I found at a dollar store. I still intend to make this smaller so I can easily carry with me. I do have access to a 3D printer so it was easier for me to print the parts I needed. But all the parts could be very easily cut from foamboard.</div>

Spectrometer Version 2 and 3</h2>

Here in the first version (image 1) you can see the camera and the diffraction grating are mounted on the right side at a 30 degree angle. Both camera mount and grading are 3D printed but can easily be made by using metal or plastic 'L' brackets.<br />

<br />In this image (image 2) you can see how I mount 2 single sided razors to create my slit for the light to go through to the diffraction grating and then to camera. The razors have a very sharp edge and I am able to make very fine slits for the light to pass through. There is a small notch in the razors that the screws go through that allows for adjustment of the blades to increase and decrease the width of the slit.<br />

In this 3rd image I am still working on this spectrometer. There is a camera holder with a 30 degree angle positioning, next going to the right is going to be a grading holder (the hole has been drilled to hold it in place). From there we go to the slit and then the sample holder. All these I have 3D printed. On the right side of the box you can see the hole drilled out to mount my LED light. I intend to use different light sources that have - white LED, RGB LED for different colours, UV LED, IR LED and different lasers, red and green for now.<br /><br />Both cases are painted black on the inside. All 3D printed parts were printed in black PLA. I am using the Theremino spectrometer software.<br /><br />I am also looking at building a nano-drop spectrometer more on that later.Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com0tag:blogger.com,1999:blog-2263348972745615973.post-1857748870485042542020-05-05T14:53:00.001-04:002020-05-05T14:53:36.155-04:00<h2>

Books To Read<br /><br />The Amateur Scientist, Procedures in Experimental Physics and Pictorial Handbook of Technical Devices<br /><br />I love to read and I love to read scientific and tech books. Here are 3 that I had or received as gifts.<br /><br />The Amateur Scientist - is one I had when I was much younger. As you can see it is quite worn. I have read this book cover to cover countless times. I have done many of the experiments in this book. This book is more of a how to do of experiments written in 1960 and is named for the column that the experiments are derived from - Scientific American's The Amateur Scientist monthly column, which ran for many years or decades really.<br /><br />There are experiments in astronomy, physics, nuclear physics, rocketry, geology, math, biology, optics, etc. It is so full of different experiments it is amazing. Many of the experiments are dangerous and maybe hard to do as many items have become very hard to find. It is a great read even if you can't do the experiments. It does show what individuals can do and accomplish on their own. You maybe able to find this book as a pdf file on line. <br /><br />The next 2 books were given to me as gifts over the last few years. Both as well are older than most.<br /><br />Procedures in Experimental Physics - was written in 1938 and it covers many procedures needed in a laboratory, such as, glass blowing, optical work, vacuums, surface coating, electronics, old time photography, etc. Another great read in how build and use science equipment. A bit out-dated but a great read.<br /><br />Pictorial Handbook of Technical Devices - written in 1971, this book shows you pictures of many many devices so you can have an understanding of how they are put together and how they work. There are joints, springs, levers, belt drives, prisms and lenses, etc. It is full of devices.<br /><br />These books are out of print but you may be able to find them online. Even though they are older books they allow me to see how things can work and helps me come up with new ideas for my own experiments. I will be discussing more books in the near future. I may even start a book of the month column. In the mean time, old or new keep reading anything that interests you.Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com0tag:blogger.com,1999:blog-2263348972745615973.post-70822194031062327172020-01-19T15:48:00.001-05:002020-01-19T22:55:20.544-05:00<div class="separator" style="clear: both; text-align: center;">

<span style="color: orange;">Digital Microscope Version 2</span></h2>
This microscope views the specimen from below. Here I use parts from an old CD-Rom drive, a web cam, block of wood to hold it together, laser pointer lens, some foam board and glue.<br />

Taking apart the CD-ROM (fig 1) I keep the carriage that moves laser LED along the CD. This allows the specimen stage to move up and down to focus it. The gears on the side are used for the focusing, the bottom gear is used for regular focus and the top gear is used for fine focusing. I manually move the gears. I may look into using the gear motor to electrically move the stage.<br />

Fig 4 and 5 show the whole thing put together. You can see the stage is up and then is lowered to focus the image.<br />
<br />
To raise the magnification of the camera I used the lens in a cheap laser pointer and mounting it on the lens of the camera. This does give higher magnification, about 100-150x but is not as powerful as a compound microscope which can get to 800-1000x. I found that when using live mounts, living organisms many times it is best to view them from underneath.<br />
<br />
All the parts I had were just laying around which made this a very inexpensive build. I am sure that it is easy to find a junked or used CD-Rom or DVD. The camera is just a cheap webcam again something you might be able to find from a friend or thrift shop. Mine was a dollar store purchase for $3. I find that this microscope does work better than my first version, especially with the focusing.Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com0tag:blogger.com,1999:blog-2263348972745615973.post-14754274437810905132019-12-12T22:11:00.000-05:002019-12-12T22:11:06.853-05:00<h2>

<br /><br />In this picture you will see I found some plastic dropper bottles, which can be used to hold microscope stains or chemical solutions for experiments and storage. These bottles fit nicely into the lipstick holder I found there as well. It perfectly holds 12 of these dropper bottles in nice neat rows. The top row is larger and does not separate the bottles. I hold alcohol swabs (another stocking stuffer) in the top row.<br />

<br /><br />In this picture there is a q-tip holder and q-tips. I use these for alcohol and acetone applicators. The 2 bottles have a push top that allows for the pumping out of alcohol and/or acetone. Cotton balls and a container to hold them. Cotton swabs, smaller plastic jars that can hold chemicals and specimens in.<br /><br />I have also found medicine droppers, food colouring, etc. As can be seen here there are many inexpensive items that can be used in the lab, that are inexpensive enough for stocking stuffers.

Spectrometer<br />
<br />
I am trying to build a spectrometer. The first figure you see of the spectrometer that was purchased from Public Lab by friend that he has let me use. It works well uses a DVD for a diffraction grading. The biggest concern with this product is the camera inside is always coming loose (fig 2) and there is no place to put the sample that you are testing. Need to make a sample holder.<br />
<br />
https://publiclab.org/wiki/desktop-spectrometry-kit-3-0<br />
<br />
In the third figure (fig 3) you see I am using many of the holders from my optical bench except I picked up a magnetic white board to hold these holders. It is larger and being white I can see measurements on the red ruler much easier.<br />
<br />
I 3D printed a slit and a sample(cuvette) holder and used my own diffraction grading that I purchased from Amazon. For the camera I am trying a PS3 camera that I found for $3. For the software I am using Theremino spectrometer. There website has plenty of information about spectrometers.<br />
<br />
https://www.theremino.com/wp-content/uploads/files/Theremino_Spectrometer_Construction_ENG.pdf<br />
<br />
I will be continuing the spectrometer build using different web cams and enclosures. I will keep posting as I build it.<br />

<span style="font-weight: normal;">With a metal cookie tin, first surface mirror, clear CD holder(beam splitter), laser pointer or other light source (LED), magnetic tape strips and 3D printed holders I am able to put together a very simple optical bench.<br /><br />The first surface mirror which I found at a surplus store is made into smaller pieces. If you can't find a first surface mirror an old hard drive plater will work fine. A first surface mirror has mirroring on the front glass surface and not on the back side of the glass such as most mirrors.<br /><br />I am lucking that I have access to a 3D printer. It is one of the best tools for making things you want to build with out having a metal or wood working shop.<br /><br />I 3D printed holders for defraction grading film, polarized film, laser pointer or LED light source, light slit, mirrors, beam splitter, camera, etc. I use magnetic tape strips and mount them on the bottom of the holders so they hold on to the flat metal surface of the cookie tin. I super glue the magnetic strips to the 3D printed object. I am finding the tape strip is not holding very well to the plastic.<br /><br />If you don't have access to a 3D printer you can use metal "L" brackets or Lego parts or even plastic that has 90 degree angles to make your holders. Even flat plastic can be bent using a hair dryer to shape the holders.<br /><br />I built this because I am going to try and make a spectrometer. I will talk about this later.</span></h4>

DIY Digital Microscope<br /><br />Staying with microscopes, I have to build my own digital one. I want one with viewing from underneath.<br /><br />Using a Dollar store $3 webcam, a piece of plywood, 3 4 inch bolts, 5 washers, 6 nuts, 4 wingnuts and 2 small pieces of 1/4 inch plastic. The only item I purchased was the webcam. Everything else I had laying around. This was just a quick work around I put together to see if it is worth while making.<br /><br />I wanted to microscopically look at live samples from underneath. It actually works better than I thought it would. It looks to give about 4x the magnification, you are definitely not going to see bacteria. Though, I might be able to see other micro-organisms, I will further test this. As of yet this is not a final build, I will be making many improvements to this setup, especially with the magnification. I would like to at least get to 100x magnification. I just wanted to see if this would be worth while pursuing. And yes it is. And for a very low cost.<br /><br />In this setup I have the camera is fixed and the sample is moving up and down. <br /><br />Inspiration for this build came from here, they use a smartphone and laser pointer optics:<br />https://www.instructables.com/id/10-Smartphone-to-digital-microscope-conversion/<br /><br />Here is another link using cardboard for the build:<br />https://www.youtube.com/watch?v=cHcX0vx4FZM<br /><br />There also is the FlyPi that uses the Raspberry Pi system and camera:<br />https://open-labware.net/projects/flypi/<br /><br />I will be looking further into the this version and the FlyPi.<br />Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com1tag:blogger.com,1999:blog-2263348972745615973.post-84656434857206812022019-08-02T21:00:00.001-04:002019-08-02T21:01:39.905-04:00<div class="separator" style="clear: both; text-align: center;">

<br />
I found a few different stains for microscopy at Walmart and a pet store.<br />
<br />
At the pet store I found:<br />
Methylene Blue - which is 2.3% and you should at least dilute to be at least 1%. I like to use it at 0.1%. It can also be used for DNA staining.<br />
<br />
Malachite Green - is 0.038% therefore I use it as is.<br />
<br />
At Walmart as well as many pharmacies I found:<br />
Gentian Violet - is 1% I use as is. This is used as a replacement for crystal violet.<br />
<br />
Iodine(tincture) - is 5%, I use it at 1%. Some iodines come as 2%.<br />
<br />
India Ink - I use as is.<br />
<br />
Another stain you might want is Eosin, many red inks use eosin for the dye, as well as some red food colouring. I am trying different inks, if I find a certain brand containing eosin or one I like I will post it. Trying and experimenting with different products you might find one you like as well. <br />
<br />
As you can see there are many stains easily available to you without having to go to a specialty shop for them. Remember to always look at the ingredients of different products, you may find a chemical you need or want.Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com0tag:blogger.com,1999:blog-2263348972745615973.post-67285575596221247202019-07-07T15:48:00.000-04:002019-07-07T15:48:08.099-04:00<h2>

I have an old microscope and I find I can't look through it for long periods of time anymore so I decided to add a webcam to it. As you can see it is mounted on top of the ocular lens (Top Image) giving me the full magnification of the microscope. <br /><br />It was a very simple build requiring very little to do or obtain (Middle Image). I was lucky that the camera was the same width as the lens. At first I was thinking of 3D printing the camera holder but I had a small plastic container I had picked up from the dollar store. Once the lid was removed and the bottom sawed off, both the camera and microscope lens fit right in. This allowed me to place the camera right on top of the lens.<br /><br />I use Linux for my system so I am using the program cheese to view and record my samples (Bottom Image).Lawrencehttp://www.blogger.com/profile/05210284435194353114noreply@blogger.com0
