Swimming critters in a pond near my house (Bangalore, India)

To all the veteran foldscopers this may sound like nothing, but I am sure excited to present this video to you: https://youtu.be/6UOBy8ztLJQ It was hard work. My lens was dirty, and the slides were scratched up, despite my best efforts. Then thanks to Laksiyer and EzekielJakub, who suggested phase contrast, I tilted the foldscope. Lo and…

My first experience with Foldscope at ICGEB, Delhi and NCMR_NCCS, Pune

I am a microbiologist and can very well understand the importance of microscope in my day-to-day research.  I read about Foldscope somewhere is 2015 and since then I was keen to have this frugal microscope.  Last year DBT, India invited proposal to use Foldscope in various activities, including research. I reacted promptly and submitted my…

A simple hack for reflection/epi-illumination using the foldscope

I have been wanting to post on this for long. There is a very simple way to achieve reflection/epi-illumination microscopy in the new foldscope. For this, I use a simple LED hack that was described by Marie. See https://microcosmos.foldscope.com/?p=13486.  This LED unit can now be inserted from the side as seen in this video. The video…

Fun time with fibres and other things

From the clothes we wear to the paper on which we write, these things are made of fibres. Fibres of polysaccharides. Just how amazing these look under a foldscope…   Paper may look smooth and uniform as viewed from the naked eye, but microscopically a different story is seen.     Cotton fibres seen through…

Foldscope: First trial

Today we started exploring the Foldscope, and we started by observing Cucurbita b.w. slide and we were amazed by the performance of the simplistic and efficient Foldscope. https://sites.google.com/view/ceglab/home

ASSETT and Foldscope: A marriage made in microcosmos heaven

The past 6 weeks or so I have been tinkering with Tetrahymenas thanks to the wonderful ASSETT program run by Cornell University. ASSETT or Advancing Secondary Science Education through Tetrahymena is an NIH funded program that provides modular science education material for schools, using Tetrahymena as a model system.  Each module is well designed keeping the…

Hematologia

He estado estudiando la morfología y las patologías de los eritrocitos en Medicina Veterinaria. Pero he tenido dificultades en cuanto al enfoque por lo que es una célula muy pequeña, mas sin embargo hare lo posible dar a conocer mis resultados.

Mosquito Claw

Like many other users a mosquito was annoying me, I killed her and viewed her anatomy under my foldscope.  After tweeting the focusing I finally managed to get a clear picture of her leg, wing, and most interestingly her foot pad. As you can see in the image mosquitoes have claws.  How cool is that?…

Captured rat skin section by Foldscope

I was really very anxious to see my histology slides after attending the Foldscope workshop organised in ICGEB by DBT on 16/04/2018. I am happy as I could focus the section with Foldscope and mobile, which I couldn’t do in the workshop. pressing the sample stage folds in mobile phone view, section get nicely focused….

Getting the best out of a waste product

About some weeks ago while again trying to observe combustion, the plastic that held the lens got molten and the lens popped out. I am quite grateful that Laks sir sent me another foldscope and also that he sent me polarizing filters. To obtain better images I stuck a small piece of filter on my…

Red hair? or parts of reproduction?

So, this time I am in a village area surrounded but trees, insects etc. I wandered arundel searching for a good thing to discover the wonders of. I found a fallen flower with a interesting looking stigma.so, I whipped out my foldscope. (Sorry, can’t focus better) BTW my stained blood pt 2 is due in…

A long journey to explore WATER – BACTERIA

I got in touch with the foldscope team last year, to develop some workshops within the program I was implementing for work. “Innovation with purpose”. The program consists on implementing an innovative technology “plasma water sanitation system” to guarantee access to secure and potable water for vulnerable people. Our vision is to connect advanced technology…

Diversity that boggles our minds – polychaete worms

Photo: “A variety of marine worms”: plate from Das Meer by M.J. Schleiden (1804–1881). In 15 minutes of looking at the same rock I collected on the beach, I found more than 12 different species of polychaete worms. Some of them were swimmers; wriggling in the water column. Some of them had fans, others appendages…

Happy Birthday, Mr. Carl Zeiss!

On September 11, 2016 the town of Jena, Germany, celebrated the 200th birthday of Mr. Carl Zeiss. I am sharing here some impressions from the personal life of Mr. Carl Zeiss – one of the great pioneers of microscopy – as told through the events of his 200th birthday celebration. Carl Zeiss Jena was originally…

Bryozoa saga continued – part 2

If you saw my previous post; I am stuck looking at billions of sargassum leaves on a beach – and Bryozoa covering almost all of them. See here. So I started poking in the water in hope of catching some fresh macroalgae to show up.. and after some adventures – did get some on my…

A floating partnership – Bryozoa – Akumal, México

As humans, we all value a piece of land to call home. It’s not so different sometimes in the ocean. Many invertebrates would colonize just about any surface you can find in the open waters. And Bryozoa are masters of colonizing just about anything.. even if it’s a floating algae. I am on a peninsula…

How aperture affects image quality

When I first heard about Foldscope from a friend in 2016 I became curious. Until my Foldscope arrived in early 2018 I started experimenting with ball lens microscopes myself. Please see a photo of some of my models. When I first used my new Foldscope, I was impressed with the good image quality. I attribute…

Foldscope Workshops in Haiti

Here are photos from a workshop conducted in March of 2018, which was held in Cite Soleil in Port-au-Prince, Haiti. The students (and educators) at SAKALA (http://www.sakala-haiti.org), the community center established by Daniel Tillias for children who live in the Cite Soleil neighborhood, were fascinated by their ability to investigate the extraordinary world that appeared through…

Leeuwenhoek’s Microscope

Here are some pictures from the Optical Museum Jena, Germany, of the historical Leeuwenhoek Microscope. Please enjoy. The pictures were taken on the 200th birthday of Mr. Carl Zeiss, the founder of the microscope company Carl Zeiss Jena. Leeuwenhoek’s single lens model was the leading microscope of its time until Mr. Zeiss succeeded to reach…

Foldscope Project- D,M,S

These are pictures of a leaf through the lens of a foldscope. We can see the veins of the leaf as well as the Lamina. As you can see the leaf is very bright, we used a flashlight to be able to see the details of the leaf.

First time using a foldscope: Amazing!!

Foldscope Discoveries Here in Squamish, BC at Coast Mountain Academy, we found charcoal from the fire pit. When we put a sample in our foldscope, we thought it looked very beautiful. Despite nothing moving around, it was a great first discovery. We look forward to using the Foldscope more to discover new things and change…
