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…

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.

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…

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…

Life in a pedestal pond

Life in a pedestal pond Hyderabad was once a city of beautiful lakes and ponds and to some it still seems so. Our place-names record long-lost water — Gachibowli (well), Nallakunta (pond), Patancheru (lake), Chaderghat (riverside), and many more. As we continue to lose our water sources to urban sprawls we experience the seamy side…

Capillary action occuring on paper

One thing we often do while preparing any wet mount is removing excess of mounting medium; mainly by making use of blotting paper. Wondered how blotting paper takes up the excess medium so quickly? A phenomenon called capillary action comes into play. Blotting paper consists of several hydrophilic substances and water (most common mounting media)…

Preparing slides for demonstrations

For fundraising and showing off Foldscopes I find it a great idea to have pre-prepared slides ready to go on the run! Here are a few examples I have put together. If you are looking to fundraise, there is no better way, than to put a foldscope in the HANDS of donors with ready to…

Accidental things

I wished to observe a transverse section of the ovary of Hibiscus flower. Took a section with a shaving blade and observed it using the magnifier provided in the kit. I was being told repeatedly by my botany teachers at college that it is impossible to get longitudinal section of ovule of any flower. One…

Compound Eyes

Unlike us gigantic creatures, arthropods do not have just two simple eyes. Everything is compound in the microscopic world. A post dedicated to some of the compound eyes I have observed as per instructions in the post  https://microcosmos.foldscope.com/?p=29111 and also by sandwiching the specimens between a coverslip and a cavity slide. 1. Housefly :    …

STEM PANAMA!

Ciencia507 Foldscopes in Panama!! #NiñasEnCiencia Women teaching girls Science! Our founder and President of Conservación Panamá Inc a U.S. 501(c)(3) MELVA OLMOS

Going electronic

Observing this wasn’t planned exactly before, though boredom got the best out of me. Studying for exams were a bit tedious thing… hence this is what I did. Armed with a foldscope, all I could see was my target which was the computer screen, which had all ebooks in it which I was reading at…

Ant Structure observation using foldscope... Foldscope prepared by my brother master frank... 4th grade

FROM THE FIELD: Boil that water!

* I was in the field today in Panama collecting butterfly photos for a project we are working on. Its dry season so not much water available in field. This reminded me of some tropical forest survival/safety training we have our staff complete. DONT DRINK THE WATER. This is why! Thanks to my pocket deluxe…

Fiery foldscoping!

I was curious about how chemical reactions would look like, microscopically. Particularly, combustion. However, observing one on foldscope wasn’t easy as putting the flap on would immediately extinguish any burning object. That could be solved easily by not putting the flap (it was obvious). However recording a burning object and even taking care to record…

Worms in an aquatic sample

Curious about what microbes might be found in the water that accumulates in the container below potted plants, I took some samples in a test tube. What I then found out were a large number of white-colored worms wriggling in the water. These were less about 5mm in length. At first I assumed these might…

Nauseous? (NSFW warning)

There were some weird, tiny insects on walls of my bedroom. Wherever those would be present they’d leave some faintly dark patches on the wall. (I realise now that I should have foldscoped those too) There was a lizard that would often show up to eat those insects. Would eat atleast 5-10 daily. I caught…

From Embryo to a Cute baby…

Lying in one corner of my room was a female spider who had mated and laid eggs into a sac. I took those eggs and kept few in a cavity slide and sealed it, the remaining eggs still being inside the egg sac kept on a watch glass. You can see how one egg appears…

Seagrass & Algae

The waves washed up a lot of seagrass and algae on Bulabog Beach, Boracay, Philippines on a recent stormy day. I collected a few samples to prepare for marine biology classes with Foldscopes. I first examined the specimens for hitchhikers like this juvenile sea urchin and returned them to the sea. There were two seagrasses…

Snail babies (and friends!)

Awhile back I decided to adopt a couple pond snails because my water lily pot had been getting a little messy. They took to the pot immediately, munching away at any dead leaves and cleaning the glass. It seems they may have adapted to the pot a little too well as when I returned to…

Polarized explorations part 2

Hello everyone, There are going to be tons of pics in this post so I better limit the words. I have foldscoped 3 compounds here – Citric acid , L-cysteine and Potassium dichromate. Recrystallized Citric acid Just while I was foldscoping these citric acid crystals an orange caught my attention! I thought Why not try…

Moss wet mount

  Methods: I prepared a makeshift wet mount slide with a spacer. I used three pieces of tape to block in three sides of a square to serve as the spacer and the drop of water is placed at the center of the square. I cut out a square of plastic slightly larger than the…

Cnidarian explorations in Mozambique

Recently, I had an amazing opportunity to try out my brand new Foldscope that I got through the Kickstarter campaign. I was on holiday near XaiXai in Mozambique and took my Foldscope to the beach to see what I could find. Two different cnidarian species had washed up on the beach: blue bottles (also known…

Trichomes on Flower

This is an image of the lowermost part of a flower where the petals converge. I attached my foldscope to my phone then stuck the end of the flower into the hole for the lens until the object came into focus. I oriented the foldscope towards a source of light since the LED that comes…

My first observation a flea

For my first observation with my new Foldscope I wanted to go back to a Robert Hooke classic, the flea. Last summer my cat got fleas, so I collected some and preserved them in alcohol. I made this perminant slide. This image is full frame, no cropping, taken with an iPhone 6 and the Foldscope…

Exploring a Slime Mold-2: Tracks outside and within

Continuing from my previous post, you can imagine that all my free time is spent trying to do as much with the slime mold. By now I am quite certain that this is some kind of Fulgio species (perhaps Fulgio septica). However,one needs to really look for several traits before deciding the species, and so…

Gilroy Workshop Fun!

Yesterday I attended a wonderful Foldscope workshop in Gilroy, California! Alongside a great group of educators, I was able to practice my Foldscoping skills. Here are some sights collected from a mysterious bucket of pond water… Excited to practice, practice, practice and explore more soon! 🙂 -Rebecca

Creature Eating Dead Spider

I was looking at a dead daddy long legs spider found in a cobweb, and discovered this creature eating it.

Marine Conservation & Education

Hi Everyone, I just received my Foldscopes in the Philippines. I will be working with educators and other non-profits to bring Foldscopes to kids here. My focus is on fishing communities so I am grateful for all of the ideas I find in the Microcosmos for marine-related subjects and low/no-cost projects. I look forward to…
