Part 1 - Ideation

Luming and I partnered up for this project. We were in between working on some sort of wearable but also interested in focusing on computation. Luming had the idea of creating a one-bit adder and we went with it. I find the relationship between basic computation and renewable energy interesting. Also a great opportunity to familiarize myself even more with bit values.

We started working on setting up the panel and measuring voltage. Because we need a steady source of power, we needed to focus on powering the panel in such a way that we could achieve that. We found a micro usb in the junk shelf, which we then realized wasn’t working and the reason why we weren’t getting enough voltage.

When connected directly to the source, we were able to get a constant 5V power.


Our next steps are figuring out how to power both solar panels (hopefully 3) with one power source and trying out different gates to see what works best. We are following this source:

Part 2 - GATES!

This part was without a doubt the most challenging. I had never worked with logic gates before so it was an awesome learning experience!

We started working on the gates one by one, separately and then trying to combine them. One of the most difficult parts was choosing the right resistor - it took A WHILE. Also something else I will never forget is not all transistors have the same setup so based on the model check where the emitter and the collector is.

Day 3

We finally did it!!

Part 3 - Fabrication

For our fabrication, we decided we wanted to have long wires and a “messy” aesthetic as a commentary on the inefficiency of computers. Here is where our project broke and we have been working on debugging.

On April 10th we finally managed to debug it and it worked using a battery. We still need to test it with the solar panels.

Updates coming soon.
