This project encourages students to check with different sample…!!

In that case, why not suggest an easy method to make a microscope reserving such tough methods for later period! Yes, that means we should go for some specific web cans which are easy to manipulate for our purpose!

Yes. The hunt for a model that makes the fabrication easy is on.

The time taken includes the time to mull over design aspects, provide flexibility and use whatever material I had on hand. This would be the work for the facilitator based on available cameras and materials in his region.
Once the design work is done, actual building would take around 2 hours for the sticking method or bending method. If we do away with the screw mount it becomes even easier and will take 90 minutes.
MAking printable templates which are stuck on sunboard / acrylic and provide exact and ready cut lines will shrink the make time to an hour.
Once one starts tinkering there will always be multiple paths to achieve a defined engineering goal, a very vital aspect of STEM.

@jtd @GN @Arunan I think we can also make a better microscope that would be cheaper expecting one has a android mobile phone. I made it myself when I was in 5th grade.
Requirements:
- Flashlight
- Android Mobile Phone
- Laser light ( It is very cheap and the lens inside can be used to get good quality suitable magnification)
If you don’t have a need to record you don’t even need a mobile phone. The magnification though might be a bit less but it is pretty cheap and easy to build. It requires only a few hours. Plus it will be portable and you can carry it in your pocket.

- It is as simple as taking the lens from a laser light.
- Then mounting it onto anything preferably a bottle cap by drilling a hole into it or by just making one by melting plastic.
- Now cut the bottle in half and take the upper half.
- Place your sample on anything transparent and preferably scratch less this will be your slide.
- Now place this slide on the opening (mouth) of the bottle.
- Place a flashlight on the lower opening made by cutting the bottle in half.
- Now put on the cap with the lens and as you tighten or loosen the cap you can adjust the distance between the slide and the lens.
- You can if you want now also use your phone to get greater magnification by placing it on the top of your lens.
This is the procedure to make one. I will soon draw and post the design @jtd.

@jtd there is also another method using which instead of a fully colorful picture we can make a shadow microscope.
- We just need to take a drop of water preferably on a toothpick and then just shine a laser at it and see the shadow on the wall of the organisms present in it. The laser will be refracted and so the shadow will be bigger than the diameter of the laser light.

Why not create one in makers lab, @pratit

Why not start making it and post pics at every instant so that it will be crystal clear to everyone who wants to make the same.

The only thing we would require for the above is any cheap toy laser.
For the next one any laser would work until it is of low enough power as not to evaporate or harm a specimen in a single drop of water.
