As computing becomes more ubiquitous in our objects, designers need to be more aware of how to design meaningful interactions into electronically enhanced objects. At the University of Washington, a class of junior Interaction Design majors is exploring this question. These pages chronicle their efforts.

powering the LEDs...portably (Charlotte and Kendall)

Kendall and I used RGB LED strips to light our lamp. These caused us a bit of confusion at first, as we were very unsure of how much power they needed and how they should be powered portably. We realized too late that we needed power transistors and had to order those after all our stuff had already come! Luckily, Adafruit was pretty clear on telling us what to do and what to buy (https://learn.adafruit.com/rgb-led-strips/usage). We went to Metrix to purchase transistors and were looking for the specific ones mentioned by Adafruit, which were impossible to find among the hundreds of unlabelled pieces they had. We even asked an employee and he had to admit that he really had no idea what the difference between certain types of transistors is. In the end we ordered the ones we wanted but also had a few random ones from Metrix as back-up. Luckily we figured out how to wire everything and our lights didn't blow out, at least not because of the transistors..
