Figure 5.1 - Beginning of soldered LED matrix
That's all we have for this week! On next weeks agenda is testing our matrix for light intensity.

Week 5
This week marks our second attempt at creating the LED matrix. As we found many problems with the conductive thread and epoxy combination, we decided to try soldering LEDs directly to copper wire. This method should allow greater flexibility (the thread became surprisingly brittle) as well as an easier way to fix errors (solder can be taken off). The start of the new matrix is shown is figure 5.1 below.

The team is showing a lot of ingenuity and creativity..... keep going!
ReplyDeleteUnfortunately, soldering the LEDs to the copper wire was not successful. As the wire heated up, previously soldered LEDs were displaced. This created a vicious cycle of soldering LEDs, disrupting the already connected LEDs in the wire, having to re-solder those, and messing up more LEDs. This idea was aborted, and the method from the week 6 post was implemented.
