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. […]

click the link for Our groups documentation of the development of the cat feeder. also see links to the flicker page for more pix and code at the bottom.

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 […]

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 […]

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, […]

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, – […]
