Sensor Network: Data Logging and Visualization

01-Mar-10 | 31,427 views

I’m working with Sebastian and Michael as “visualization” team for the sensor network assignment for this week’s Sociable Objects Workshop. It’s very challenging for the whole class to work on one single project, but so far it went on pretty well. Tasks are split and assigned and we also find ways to work with dependencies […]

Storytelling stickers update

09-Apr-09 | 6,375 views

Wrapping up what’s happened to the storytelling stickers! THE READER The RFID reader is working! It took a while though. I did some search and ended up taking arduino codes from featuring the AF_SoftSerial library. It’s very well written and comprehensive. The scripts added a kicking off step and a disconnection detection as well. […]

Everyone with crazy ideas of the keyless entry must be living in a dorm!

07-Nov-08 | 8,664 views

I ran into this post today and apparently it’s a similar but much savvier implementation of my unlocking system. Really like the touch sensor use! What’s really sad is I was locked again outside my bedroom two weeks ago at midnight. I cannot always stick my arduino to the door. Nice work Alex! Check out […]

UPDATED: Pcom lab catch up and GO OUT

29-Oct-08 | 4,824 views

The transister lab looks fun because I like these DC motors since young. They have a unique smell while spinning really fast. In my impression they could work very well with just 2 AA battery (3V) in a toy car, so I’m curious about how would it be with 9 or 12V. First I hooked […]

PCom Update: multiple serial input

15-Oct-08 | 3,453 views

I’ve been mostly working on viz class and pcom mid term over the weekend. One big thing is I once made the eight-buck-deal RF Link work in the studio, but never succeeded in testing again since I went back to the dorm. I used software serial library to utilize digital pins as serial input/output and […]

PCom: Serial Input in Processing

08-Oct-08 | 4,717 views

I do enjoy the force sensor I got in week 5′s application class so I’ll definitely use it more in the assignment! First I revisited the processing codes I wrote for week 2, which now seems to be a total mess. I didn’t know about the serialEvent callback then so I parsed the serial input […]

Solution for Lockouts

01-Oct-08 | 4,955 views

Lockouts are irritating. especially when you live in a dorm, at midnight, your roommate is sleeping, and backup keys are two hours away. Here’s the self-service solution. I should have made a much more complex combination lock with multiple sensors and flexible customization functionalities, but it’s two in the morning… so maybe next time… Secret […]

Physical Computing Week 2: Analog!

17-Sep-08 | 5,161 views

Hooking up the following stuff according to the diagram was easy and quick. And a resister of 220 10K Om is working ideally to create an ouput range of 0 – 930 (from total darkness to direct shine of torchlight) for the photocell. I changed the switch from last week to a much smaller one […]

Digital I/O with Arduino

10-Sep-08 | 7,167 views

I bought my first Arduino boards in 2007 and never touched them again ever since setting up the famous “blinking LED” code sample. It does recall some memory when I have my hands on the chips and boards and wires and stuff… again. The Arduino I have is an old NG(Nuova Generazione) rev C, which […]
