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 […]


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, – […]
