It is about 70 mm x 100 mm. However, it is worth noting that the PCB is double layered allowing it to be more space efficienct by having tracks on both sides of the board.

Thanks! Yes, an OLED screen would have probably been easier, but I already had these extra PCBs from an older project which is why I decided to use them.

Thank you!

Thank you!

Thank you! The circuit board you posted uses SMD (surface mounted) components which can be tricky to solder if you don't have the required specialized equipment. You can however redesign the circuit using through-hole components (such as the PCB I designed above) and it should be very possible to do as long as you have access to the necessary schematics...

On the contrary, it is specifically useful for these areas as they tend to suffer most from plastic pollution. Developed nations tend to have established waste management systems. Not to mention, many countries export their waste to developing countries. It is shocking to realize just how widespread and far-reaching our uses for plastics have become. Not to mention, which recycling facilities are you talking about (especially ones that exist in developing nations)? I have never heard of a recycling plant buying waste plastic. They are the ones who are usually paid to take the plastic (especially from developed nations). Regardless, perhaps this article explains this situation better: https://resource.co/article/plastic-pollution-caus...Thank you for your question :)

Apologies, perhaps 'developing areas' is more appropriate. Also, perhaps you might find this article interesting in response to your comments on plastic in poorer communities: https://resource.co/article/plastic-pollution-caus...

Thanks! I used Fusion 360 (Autodesk) for CAD.

Wow! Very nicely done, I would never have thought of such an idea...

Well, plastics are all around us. In our products, disposables, and everyday items. While I have only tried making bricks from High Impact Polystyrene (HIPS), I have yet to try other plastics. In particular, Polyethylene (PE) as it is the plastic used in making disposable bags. A material that I am sure no one will have trouble getting a hold of in the near future given it's widespread use and availability.

In the description, I did mention that the product should be able to operate without electricity, yet I did use an oven. However, as mentioned in the reply above, the intended method of heating is by fire. Unfortunately, I wasn't able to simulate this as it requires a fire and I was working indoors, which wouldn't have turned out to well if I had tried (CO poisoning). Fortunately, I did have the next best alternative which was an oven. As for water, in many communities, the problem isn't the lack of water, but rather the lack of drinking and potable water. This solution, fortunately, doesn't require clean water and as such, any stream or a nearby body of water will work in terms of cooling down the brick. You are right though, I should have made this clearer in the Instructable, thank you…

Thanks! This prototype is a stepping stone. The intention of such a product is to enable different communities to be able to take waste plastic and put it to good use. In this case, through the production of bricks that can be used for building materials or even as a product to inspire social entrepreneurship in these communities. Ultimately, if we want to be more sustainable, we need to start transitioning into a more circular economy. That means producing less waste, and repurposing & reusing the materials we currently have. We can't rely on single use products and finite resources forever. This project is just meant to represent one more step in the direction towards that circular economy.

Thanks!

Thanks :)

Thank you!

Absolutely, there are many possible applications for such a product.

Incredible detail and an amazing project! Very nice work...

Yup, I am using an Arduino Nano instead.

Where in the code is the colour sensor setup where pin 2 is attached to SDA and pin 3 to SCL. I consistently get the 'Sensor Error' feedback and am trying to troubleshoot the problem via the code...
