I’ve been working with Liesje on the pcomp final and we had a lot of fun playing with magnets. Now it comes to a crucial question what are we gonna do to put some real pcomp into this project. Finally today we came to narrow down our ideas and focused on a still exciting solution! [...]
The biggest challenge for me so far is to narrow down the options and ideas. The semester is too short to explore everything that interests me, so that makes it even harder to decide on a “final” project.
Proposal 1: The Sphere
I’m taking the visualizing the five senses class this semester and am always curious about [...]
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 up [...]

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 [...]
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 in [...]
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 revealed. [...]
Spent still over two hours though., most of the time tweaking with the multimeter.
THE REGULATOR
Output: 4.97V
Input:16.47V
Voltage over LED: 2.088V
– over resister: 2.70V
LED IN SERIES
I don’t really have much to say about that…
LED A:2.52V
LED B:2.48V
Seems perfect? Not able to light up 3 LEDs in series though.
LED IN PARALLEL
Voltage over resistor: 2.86V
– over LED: 2.06V
Amperage [...]
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 which [...]
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 is [...]
