Physical Computing Night Light Circuit March 22, 2010

The first thing for Physical computing we had to do was create some kind of circuit, so I decided to kind of go a little farther. I created a night light circuit that has problems ūüėõ Basically the circuit is supposed to turn on automatically in the dark and turn off in the daytime but can be turned on by pressing the button. I’m not actually sure what’s going on at the moment. The LED never fully turns off and it and only gets brighter when you press the switch. I don’t know if this is a characteristic of the 74ls00 (Quad NAND Gate)chip or not but when I check it it’s putting out a constant 1.4-1.6 volts and when I press the switch it puts out 3v (I have a little 3v coin battery on it) I’m pretty sure the chip is supposed to send out zero voltage when putting out a Low Signal.

Since the 74ls00 chip can only supply like 24mv it’s not strong enough to supply the LED to the brightness and it could hurt the chip so I put on a transistor to basically create a gate that activates when the chip sends it a High signal and routes power directly from the battery instead of through the chip.

So attached are the different revisions of the schematic and some poor quality photos of the breadboard. I’ll update with a cleaner setup, I have to put the circuit back together.

Still exploring with the scribbles March 22, 2010

I’m still exploring a bit with the scribble technique and more of a stream of consciousness type¬†exercises. ¬†I find they really seem to help with keeping my mind open. ¬†The characters just kinda came out of nowhere, they’re so weird and that is why the scribble technique is so awesome.

Ok so I decided to paint the weird thing into more of a “cartoon esque” thing.

So I’ve learned of a pretty neat way to push out or explore really crazy forms and shapes in a fun way. ¬†Basically you start off with a quick scribble without looking at the paper and trying to see a form inside of it. ¬†This is a pretty awesome way to explore new forms for whatever you’re designing whether it be an actual product or a cartoon or spaceship. ¬†Basically just turn the form into something. ¬†I’ve included an already posted picture but it was the same process except I used a figure drawing and saw a face in the form. ¬†I’ve included the scribble and then 2 other forms that came out of different scribbles.

It seems difficult at first but it’s a good way to free your mind. ¬†It breaks you from the¬†repetitious style you would normally create.

Recorded with iPhone March 12, 2010

Ok so these were a short while ago but I figured I’d put it up. ¬†I’m actually pretty surprised at how well the iphone’s microphone is. ¬†The recordings are a little heavy on the bass but that’s because I had it really close to the amp. ¬†And with the song, it was sitting in the same room with all of the instruments. ¬†We were all just jammin and I figured I’d turn the mic on… You might¬†need to turn the sound up though to be able to hear it loud enough.

So for Digital Sketchbook, we had to draw a person, a dog, and a bowl of fruit. ¬†I don’t if it was supposed to be separate or together but I put them together. ¬†If you can’t see the dog and the bowl of fruit you might need to rotate the image. ¬†¬†

First Time with Hypershot March 12, 2010

I decided to try out hypershot for the first time on one of my projects and was¬†thoroughly impressed by it. ¬†I was able to make a turn table movie (kind of, I was able to make the individual frames but still had to compile them together which was a pain) and make some pretty awesome environment renderings. (I can’t post the video on this blog without upgrading so I’ll probably upload it to another site and link it over at some point.)

For the renderings, I found a high res image of a hospital environment (I had to paint out the gurney that was already in there) and used it as a backplate for the image and for the HDR Image (High Dynamic Range) I used the scenery of a kitchen for the lighting and reflections which turned out pretty decent I thought.

The Project was to work with Carestream to help them design a new type of CBCT Scanner. ¬†It’s basically an extremity ct scanner.

I’ve never really done graphic design before but I figure I might as well give it a shot. ¬†I was helping Colleen with some ideas for some graphics for the skis that shes making.

Some Digital March 12, 2010

Here’s some of the digital painting’s I’ve been practicing with. ¬†I’ve been trying a lot of new techniques and finding the fastest ways to explain my ideas and I found that digital really is the fastest and overall cheapest way to get it out there.

Hey so as a first post, I’ll just post up some older work that I’ve done to kind of get the blog rolling.
