This week we watched videos about serial communication as well as videos to help us with the fabrication side of things. I learned lots of great tips from the past residents as well as excited to try both the acrylic enclosures and Tom Igoe’s idea of lasercutting mat board as a quick solution to keeping things organized in the prototype stage without sacrificing a week to build a box. Instead, it allows you to problem solve/user test in the interim – later developing a final box that best suits your project. I also had no idea you could twist wire like in Bendetta’s tip, and will take to heart what Luisa learned about wire flexibility and UI. Will make sure to use illustrator to help me imagine my UIs
This week I revisited some of the past labs, including Analog/Digital inputs & outputs. This Friday, in addition to meeting with my super fun mid-term partner – I hope to continue to the lab review from this week, starting with Sensor testing into Serial communication labs. I also want to continue with the tone lab playing with FSRs + Flex sensors. Looking forward to the Programmable Air flyby this friday too 🙂 ❤
When you use analogWrite() to create pulsewidth modulation (PWM) on an output pin, you can change the on-off ratio of the output (also known as the duty cycle) but not the frequency. If you have a speaker connected to an output pin running analogWrite(), you’ll get a changing loudness, but a constant tone. To change the tone, you need to change the frequency. The tone() command does this for you.
For class this week we were asked to find a piece of interactive technology in public used by multiple people. On my way home one day, I saw a guy using a LinkNYC on the corner of Flatbush & Rutland Road, and was inspired to learn more about it. Originally, while passing it in the neighborhood, I knew it was a digital bulletin board for advertising, but unaware of many of its other capabilities.
It seemed like one of the difficulties is that the speaker for it is pretty faraway from your mouth if standing? So when making phone calls, there’s a tendency for it to be a less private conversation. It seemed like the person really had to raise their voice level to be heard over traffic? But it was a good solution for their dead phone, and being lost. The guy was able to contact their girlfriend while simultaneously charging their phone and searching directions.
When taking pictures of the different interface elements, another person walked by and said, “Actually works pretty good, yeah?” In an affirming way. Although they seem to be under utilized? I think its provides a lot of helpful tools: free fast wifi, phone calls, device charging, a tablet for accessing city service info – as well as maps & directions. However, I had no idea it had phone capability to make calls or and emergency 911 button and wonder if it could have made its function more “visible” as defined by Norton in POET? Would it have helped to have had a phone icon on the Link somewhere, like it has the wifi symbol? If the initiative is to replace pay phones with 7500 different link beacons, I wonder if there’s a way to make its utility more transparent? Maybe by adding a phone or map icon?
It seemed like as long as you have your own usb cord? That charging is the easiest function. That calling also isn’t too hard as well, and even better if you have headphones with you? The overall duration of the usage is very variable, depending on how long the charging takes place? or if someone just needs to look up a quick direction. But mostly was used for charging & wifi.
