Report for Hands-on workshop: Synthetic Biology application on plastic waste degradation

We had our collaborative event on 3-5 May 2023 in Sumbawa Techno Park and Brang Biji River in Sumbawa.

Kit preparation
There were 3 kits developed for this event: microplastic kit, DNA isolation kit, and electrophoresis kit. These kits were prepared and packed in Sumbawa University of Technology.

Day 1 - Plastics and its problem
There were talks given by the lecturers of the Faculty of Life Science of Technology, Sumbawa University of Technology. The first talk was the introduction of plastic in general and how it could bring problems to the environment. The second talk was explaining more about microplastic and some strategies that can be used in tackling the problems.

Day 2 - River clean up and microplastic observation
Students were divided into groups and together went to the Brang Biji River. The microplastic kits were distributed to the students before the observation. The samples of river water were taken using a DIY plankton net and divided into cups for the groups to be observed. The kit has foldscopes that were used by the students to observe the microplastic in the water sample followed with river cleanup. They took some pictures of their observations that are furtherly used as a reference for making posters. The second day was wrapped up with students making posters for the next day’s presentation.

Day 3 - Synthetic biology and its application on plastic waste management
The students presented their posters and what they can learn from the second day activities. There was an introductory lecture about synthetic biology in general that is followed with another lecture about its application on plastic degradation. There was also an explanation about some techniques that are common in synthetic biology research such as DNA isolation and gel electrophoresis that they could learn later after the break. Each group of the students got two kits for the hands-on workshop. Started with gel electrophoresis, they assembled the battery and the gel apparatus and loaded the food colouring as samples. While waiting for the running, they started the DNA isolation from banana and dragon fruit.

Here is a quick update.

We ran the first set of our sessions for teachers on May 31st. We had around five teachers participate in the session. Some of them have also signed up for the OSH forum, which should help us set up a community of Nepali teachers exploring the idea of OSH in education in Kathmandu. All the participants were also fascinated with the microbit, and have expressed interest to keep learning about it and use it in their classes.

One of the major challenges we faced was getting the microbits to Nepal. In fact, when we had run the first session, the microbits that we had purchased were still stuck in customs, and they only got to us a couple of days ago. Our delivery partner apparently had a hard time explaining what microbits are to officials. We had to borrow some from our friends for the workshop.
Now that the microbits are here, we are hopeful of running a second session for some more teachers here in the school where I work at. We are also planning to kick start some sessions with middle-school students here.
During our first session, a participant teacher shared with us a narrative that has left me feeling very strongly about the idea of cheap open-source science tools in education. She came from a lower end public school in Kathmandu, and here, most of the kids who go to public schools come from families that have very difficult conditions, often they might even struggle with meals. So while the teacher valued the workshop and thought it could be very helpful to her kids, there is no way that the students or the school could afford to bring tools like microbits to their classroom. In fact, they had been struggling to raise 20 cents per children to upgrade their science lab. This made me want to look for ways to make these tools accessible to the kids too. For now, a solution that we have come up with is that perhaps we could figure a way to share these microbits that we have, kind of like borrowing from a library.
Here are some photos from the first session. Will keep you updated on the other sessions as we run them.

Here is an update from the Foldscope Indonesian Fellow / Fab Lab Bali. Our event name is Jimbaran Fishing Communities Looking Closer with Foldscope. Due to complications with the logistic of the funds (the grant finally came in 9th June!), adjustments are made to the original plan of the workshop.

The workshop is divided into 2 sessions:

We are currently working on a small video recap of the 1st workshop session. We plan to finish Citizen Science Guidebook for Fishing Communities after the 2nd Workshop. We are also trying to establish the ecosystem for the fishermen with local universities to keep the citizen science movement going! So definitely alot of ongoing activities planned as part of the Fab Lab Bali’s Frugal Science Initiative


Introducing OScH cyclers to UNSAM

Main outputs:

  1. Translated PocketPCR guide to Spanish, and added a bit of content: Guia PocketPCR en Español.docx - Google Docs
  2. The idea was very welcome by University profressors at IIBio-UNSAM.
    • Dr. Marcela Brocco and her team have led the first round of assemblies, and tested the cyclers against their standard equipment with equivalent results. Find pictures below!
    • There will be a workshop involving a total of four professors by the end of June, where your’s truly will also attempt to convey the awesomeness of OScH and GOSH.
    • They have already committed to use the cyclers in their university courses. This means that over a hundred undergraduate students, will become aware of and use open source science hardware for the first time, each year.


Description of the results (Spanish ahead): En el gel. Las dos últimas calles son positivo y negativo con la cicladora OScH y las dos anteriores, lo mismo pero con una cicladora convencional. Hay chorreado porque pusieron mucho templado, pero da igual en las dos corridas.

Reading the manual.

Finalizing assembly.

Adding a bit of mineral Oil (whatever that is made of) on top of the PCR mix.

Next steps

Depending on further feedback and requirements from the professors, we might:

  1. Manufacture units locally.
  2. Solder and program the heated lid to replace the mineral oil (the circuits are there but they are not connected for some reason).
  3. Hopefully inspire the university to invest in more OScH for teaching and doing science. :slight_smile:


Thanks GOSH for your support, and congrats to everyone for your achievements!



I’m so happy to share that we recently organized two captivating workshops for children in our open-source community, and their enthusiasm was contagious!
Both workshops were held at the CEILAB Maker Space of Espacio Ciencia at LATU (Montevideo, Uruguay).


These workshops served as the initial phase of an ongoing project dedicated to making a positive impact on two public schools in low-income zones of Montevideo.
The children dove into the world of hands-on experimentation with low-cost devices to see brain sections and neurons for the first time in their lives with Foldscopes.


and record the bioelectrical activity generated by their skeletal muscles,



and brains

as well as the electric organ discharge of an autochthonous weakly electric fish


with Backyard Brains equipment, embracing the opportunity to explore and expand their understanding and interest in neuroscience and microscopy.

Witnessing their excitement and curiosity was truly inspiring.
We are delighted to announce that the schoolteachers expressed their eagerness to continue collaborating with us, ensuring the integration of more interactive sessions at the schools where students will conduct experiments during their regular classes.
We will also collaborate on the assembly of a school laboratory!
We are already working on the assembly of an in-silico neuron.

and soon will receive the UC2 Discovery | Core for the next activities at the schools!

We feel that these activities are igniting a passion for learning and empowering young minds with practical scientific knowledge.

We´ll keep you updated as we embark on this educational journey! :star2::microscope::brain:

We thank GOSH for the invaluable support in bringing these workshops to life!


Hello friends,

So during this grant, we ran nine Owl Prowls – free nature classes for children – in our city. The Owl Prowls were a hit! We regularly had 50-60 people showing up for each walk. Each week, we ran a different nature activity exploring a different aspect of the natural world. I made a full write-up, documenting the project on our blog here with lots of thoughts, instructions for how to run the activities yourself, and a breakdown of what worked and what didn’t.

This was a great project, and I like to think of it as a prototype for a larger roll-out of Owl Prowls in the future. Already, this summer, we have a librarian, paid for by the city, who is going around on the mobile library running activities we designed during this Owl Prowl with children across the city. In the Fall, we’re planning to run several parallel Owl Prowls across many other libraries in the city. I’m very grateful to GOSH for supporting us through these prototype events, and helping us work out a pattern that we can build to scale in the future.

Find Bri’s slides on GOSH here: GOSH - OScH in Africa presentation (final) - Google Slides

The main highlight of the event was a training workshop on the OpenFlexure Microscope. Thanks to a grant from GOSH and the Albert P Sloan Foundation, all participants were provided with the necessary materials and tools to build their own OpenFlexure Microscope. The workshop leads guided the participants in identifying and understanding each component of the microscope, as well as how to assemble them. The attendees were divided into three working groups, each responsible for building one microscope. At the conclusion of the workshop, all groups had the opportunity to view microscopic slides using their newly constructed microscopes.
Overall, the AfricaOSH in-person open science hardware workshop in Ghana proved to be a valuable experience for the participants, providing them with knowledge and hands-on training in open science hardware while fostering collaboration and awareness within the local scientific community.
