cat feeder @ work
First test proves that it does work, however, the fsr input at set needs a larger buffer as the mat is too sensitive. As the cat shifted his weight or lifted his head to get a better bite, the frs valuaes would change more than predicted and the lid would close down onto his head. […]

The Feeder has taken Shape. A little bigger and bulkier than initially envisioned, but aren’t most first protos. Most importantly – it works. and no, it is not a Hungry Hippo robot! So, what does it do you ask, well: 1. For first feeding, turn toggle switch to on position. Wait for yellow PWR LED […]

Controlling a motor
It took a little while to set up with an H-bridge and a dc motor and then, well about 2 seconds of “Its Alive!”, and then – nothing. I think my H-bridge died, and i can’t get over it…. so, how do you test an H-bridge? Motor works, as does the Arduino. Here’s what i […]

Mid-term feeder proto
We have a basic mechanism for the automatic wet-food cat feeder, from here on out known as AWCF(aus-iff (it works)), working. We needed a time mechanism, be it code or an actual clock to set the feeding time regardless of location or power interruptions, so we hacked a cheap alarm clock, which has worked surprisingly […]

I also had some problems bringing the serial-out up on Terminal, getting errors that I could not make sense of. Keep’n it on the positive: it was still a wow moment being able to control a meer ellipse on a screen. Hope to play this more when time becomes available. Having too many of those, […]

Design of Everyday Things, ch. 1
This is one of those topics that have been beaten into my head thousands of times – especially if you’ve come from an art and design undergrad. Norman had, however, a really refreshing take on design and thus the role of the designer with some effective examples. One constantly hears what design “should” be, – […]

this music bytes
My first attempts at electronic music via the arduino and yes, a piezo. if your’re curious, click hear, but don’t expect much. had to connect it to an external power source through a tip 120 so i could actually hear it. well, it may be start to something…

Analog output
In this lab, i put together a servo motor controled by potentiometer. i also managed to attach the dc motor from the analog in lab and have it control the servo, but to no suprise, there was little control other than some jerky movments – fun though. I just got a piezo and am ready […]

Observation assignment
Here is the link to my groups presentation on photo-booths for the observation assignment, hosted on Michaels blog. if anyone’s interested in the sound part, let me know and i can upload that as well. http://www.doryexmachina.com/itpblog/2006/09/28/photobooth-watching/
