Tinkering and Soldering

The Champaign-Urbana community fabrication laboratory otherwise known as the CU FabLab led our class throw 3 different stages of building a small box that has a light sensor and powered by Arduino. The class split into 3 groups, one laser cutting the box, one soldering the wires and builds together and another group worked on coding the firmware. Splitting this into groups and stages made creating this project to be much more manageable and help show how much work truly goes into the design of an item from its conception to its creation.



I have never soldered before nor worked with Arduino and so it was exciting to be able to learn from professionals and people who knew what to do. Going into the FabLab I did not know what to expect and so to know that there are so many resources at our disposal really gave me hope about how our project can be created here. The soldering material was lead based and so it was instrumental that we do not touch our faces or body with our hands and that was surprising to me that we utilized lead. However, we were explained at how the smoke that rises, aka, flux, is very toxic and so soldering with other materials makes the flux much worse. We were then given our Arduino units as well as LEDs, resistors, sensors and wires.


Each student in the group had a soldering iron in front of them and we were given a tool that is referred to as the ‘helping hand’ which helps hold wires for you to solder. There were some frustrating moments as solders operate at roughly 800 degrees Fahrenheit and so it was very dangerous as one can easily burn yourself.


Our outcome after soldering the pieces all together was 5 LEDs each connected to a resistor and then attached to the light sensor. The way the object operated was triggering specific lights when there is a certain amount of light being received by the sensor. So as you can see, the bulbs each flicker as a number of light decreases, then all of them flicker when it is pitch black.

After learning about Arduino, I became very curious as to what items can be made with it and how it operated. The website Make Use Of highlighted the many potential projects that it can be used for. Through that, I found a personal project I might work on now since I am learning the basics of Arduino. The Fablab sessions are not only very informative but it is allowing me to think outside of the box and reinforces the notion that I can build and make anything I want as long as I put my mind towards it.
