Steve Cooley Fine Art

I got an arduino ethernet shield for xmas, so I wanted to check out if I could get it talking to quartz composer… and… I did! woot.

Every week, seems like there’s some new awesome tool to make the iPad a tool for creative outlet.

I just picked up ArtRage for the iPad, and it’s pretty awesome. I’ve already been on a major cat-drawing kick lately, so when this new natural-media style drawing/painting app became available, I dove right in with this:

Brushes app is another great tool for drawing/painting on the iPad. Here’s an example, although you’ll find another piece I did further down in my posts of some orchids that also show off what brushes app can do.

So far, there are some really great apps out there for the iPad that have one or two great features that make them useful. I think there’s still a perfect storm of features that I want to see.

1. Natural media synthesis/mimicking — artrage
2. record all brush strokes and actions for playback for either movie or high res render on a desktop machine – brushes.app
3. remote palette with ipad, iphone, or desktop.. one of them anyway. I have all three, let me use one of them that I’m not drawing with to be the utility space so I can focus on drawing on the drawing space. Remote Palette

These apps are fun to use, and I’m going to keep using them. The reality is that these are great apps to use for illustrations and for fine art if you’re going to display them online. Prints from digital art just don’t have the marketability like actual paintings, so the destination for these pieces has to be different. When you see covers of magazines being done with these types of apps, yes, that’s exactly where you can make some money being an expert at using iPad painting apps. Doing live portraiture using an iPad, yes. Using the iPad with a painting app to do a plein air sketch to use as reference back in your studio… perfect. The utility of using the iPad for fine art is there. No question in my mind. It’s just not a straight A to B type of path. Chances are good that you’re just not going to make a living as a fine artist using digital tools exclusively… so you need to figure out where the career path is using digital tools, AND/or keep using traditional media. “AND”… as in… do both. These digital tools are really cool. And so is having an actual painting that you painted without a computer. Do both.

I wanted to make a piece of art for my anniversary card to my wife, so this year I used brushes.app on my iPad to paint (?) this set of orchids. I really like the reasonable limitations and extremely flexible set of tools. I went through the tutorial a while back and started remembering the color blending a ways into this piece. I’d done several pieces of abstract work as per my normal mode in brushes.app, so doing something representational was something new for me. I guess. I do some representational works; mostly seascapes… so this turned out pretty ok given that it’s just not what I normally do.

I had a hell of a time with this so-called-free epson printer, wasting a precious hour on changing ink and reading about how lame that is given the amount of ink left in the “empty” cartridge. Sigh. I have another “Free” canon printer/scanner sitting right next to the epson, and not only did it fire up right away, but it had full ink carts, zero clogged nozzles, and printed out a *beautiful* 4×6 glossy print for me on the first try. Whew. Anniversary card project successful.

Welp, I decided on which CNC rig to go with. I wanted to keep my options open for the future, so I decided to go with a bigger rig than I had originally planned on committing to. I decided that I could commit several continuous days in a row to assembly, setting up a major section of my garage, and purchasing a couple-few extra things to accommodate the buildyourcnc.com Blacktoe 2×4.

Here’s the timelapse of the build:

Here’s the first run:

And here’s the first real job I ran with it:

Woohoo! Very happy!

Hey, so I’ve been super busy with lots of cool stuff. I’m working on the Beatseqr project, and I’m also putting that to work with my band Haptic Synapses. And along with those projects, I’ve been building some interesting tools with Max/MSP. Here’s one that I’m calling “sCCweet!” and in this particular instance, I’ve tuned it to work on Reason’s Malström synth. (You can either say that as “skweet” or “schweet” depending on which kind of person you are.)

So… why? Well, a lot of modern soft synths have a randomizer function, but Propellerhead doesn’t follow market trends. They try to influence them.. sometimes to a good affect, and sometimes to the effect of going in the wrong direction of the rest of us. Reason has some really awesome sounding synths, it’s just kind of… funky… about a lot of stuff. So you can either choose to accept the Reason reality as a foregone conclusion, or make your own reality. I prefer to make my own. Anyone interested in getting a copy of the max patch that does this? It’s not limited to working with Reason, it can work with anything that uses midi CC messages. Leave a comment!

While making my Beatseqr project, I’ve been trying to find a reliable source for some faders / sliders / slide pots / slide action potentiometers, and I’ve been having a challenging time finding exactly what I want. So I thought I’d share what I’ve learned. Click on through to get a crazy large dose of science. Continue reading ‘HOWTO find and buy faders / sliders / slide pots / slide potentiometers’ »

Update: I’ve written a huge post on how to buy sliders/faders/slide potentiometers

As copiously stated, I have no formal training in electronics, and I’ve reached a mature enough age that I can no longer accept an electronic component as a black box, so when I come across a device and can figure out how to use it without being able to locate instructions, i feel like it’s only right to make a drawing of it and try to explain my hypothesis for how it works.

With that being said, here’s my best guess at how the 10k slide potentiometers (sliders / slide pot) works:

the 3 pin slide potentiometer (10k)

The obvious control at the top sets the resistance. The voltage in (V+) and ground (V-) pins run inline with each other, and the resistance value is read from the pin adjacent to the voltage in pin. I’m using an Arduino to read the value, and in my case, i actually needed an additional resistor in front of the voltage in pin to limit the incoming current. When i hooked the slider up directly to the arduino, it didn’t work very well, acting way more like it was a logarithmic curve potentiometer than the linear curve pot I thought it was. About 2 minutes later, it was blistering hot. Too hot to touch, actually! So, I quickly disconnected it from the arduino and added a 10k resistor in front of the voltage in, and then it started behaving much more reasonably. The values I was getting from the 10k slider were not what I was expecting, so I’ll have to dial back on the current resistor from 10k to maybe 1k and see if that helps get the values from the slide pot more inline with my expectations.

Derek and I have been working hard on building some useful tools for beat sequencing using Rosco and Max/MSP. Poking around at Max/MSP made me realize how much I understand PureData, so I went back to PD and built a comprehensive “data-in” patch to receive the OSC messages from Rosco.

Hey there, I’ve created a page for Rosco since I’ve revised it to version 2.0.

Rosco is an app that I’m working on that creates Open Sound Control (OSC) messages.  It can generate them with or without taking data readings from an Arduino.  Version 1 only had 6 sliders (one for each analog pin from the arduino), but now the new version includes being able to use 12 checkboxes (which correlate to pins 2-13 on an arduino).  I’ve revved the app, the quartz composer file, and the arduino code to all show examples how to get it going. Check it out!

Hey, come check out my arduino project box that I’m working on! That’s what the post about the SPDT switches was all about.

Here’s a video I made of some of the construction steps:
