Fun with Highways: Northern California along I-5

As summer winds down, we start to look back the many little road adventures that dotted the season. The largest and last of these trips, of course, was to Portland, which included a large stretch of northern California.

We begin on I-505, which heads north from I-80, bypassing Sacramento.

I-505 is a completely straight, flat, stretch of highway. This is pretty much true of the surrounding landscape as well, but the texture and details against this blank canvas can make for some interesting photos.

I-505 merges into I-5, which continues northward through more of the relatively flat landscape, repeatedly crossing the Sacramento River in the process. Eventually we come to the city of Redding at the northern end of the Sacramento Valley. On my return trip from Portland, I finally had a chance to stop in Redding and visit the Sundial Bridge. This modernist architectural gem spans a wooded section of the Sacramento River completely, a world apart from the town of Redding itself or the strip malls and shopping centers that line the highways. Here, clean modern lines contrast with the natural forms of trees and running water.

The Sundial Bridge turned out to be a great subject for abstract photography (you can see another shot in an earlier Wordless Wednesday). It was also quite crowded with families and groups, something to keep in mind should I ever want to use it as a setting for a more formal photo shoot.

North of Redding, I-5 climbs into the southern Cascades towards Mount Shasta. The highway here is quite scenic, but also narrow, winding, and treacherous. Eventually it opens up as one passes Mount Shasta and approaches Black Butte.

Black Butte is a satellite cone of Mount Shasta. It has a distinctive pointy shape and largely barren rocky texture, both of which make it quite prominent in the landscape. The highway curves around its edge, providing a close-up view.

Historic_US_99CA_265US_97_CAAfter passing Mount Shasta and Black Butte, I-5 descends into a wide valley, passing by the town of Weed, whose welcome sign is a popular backdrop for photographs. This is the start of US 97, which heads northeast towards Klamath Falls and central Oregon as I-5 continues due north through the Cascades towards Portland. The main street in Weed is also Historic US 99. The part of the historic route which returns to I-5 is now California Highway 265, one of the shortest in the system.

From here, the valley descends and opens further, and the landscape becomes surprisingly desert-like. We pass the town of Yreka, where I did not get a chance to stop, but might on a future trip because of some idiosyncratic road-geek things. Finally, the highway climbs upwards again towards Siskiyou Summit, just north of the Oregon-California border and the highest point on all of I-5 at 4,310 feet (1,310 meters).

Fun with Highways: Portland

My trip to Portland for BPOW included becoming acquainted with its streets and highways (and mostly not getting lost). The city is largely defined by the Willamette River, which bisects the city in eastern and western halves, and a series of bridges over the river connecting the two sides:

The vantage point is from the center of the Morrison Bridge, which combines traffic entering and exiting I-5 with city streets, walkways and bike paths. It seems to part of the theme in Portland that all these different modes come together and coexist along single routes. Looking towards the east side, the bridge connects to I-5 and I-84, as well as state highway 99E (Martin Luther King Avenue) and Water Avenue.

I-5 runs along the east bank of the river. But it also runs with bike and walking paths and a greenway. The highway, park, water and industrial zone behind them all co-exist.

I like the way Portland has chosen to co-exist with its older industrial infrastructure and highways as it plans green spaces and alternative transportation options. It is in sharp contrast to San Francisco, which can’t seem to tear down its highways and raze its gritty industrial areas fast enough. There is a beauty and attraction in preserving them while making the city for livable and environmentally friendly. The area around Water Avenue in the “Industrial Southeast” section of the city particularly retains this character. I had briefly seen it during my 2007 trip with the band that would later become Reconnaissance Fly, and for the BPOW trip I made sure to set aside time to explore. Much of the neighborhood is below the bridges and viaducts, but in between it opens up into spaces with larger warehouses.

It can be quite colorful if you know where to look.

Heading north at ground level, we follow the viaduct until we get to a rather nasty looking interchange. This is the northern terminus of I-405, which loops around downtown on the west side.

20130811-IMG_8613

There are also several city streets and rail involved here in ways I can’t quite figure out. It also oddly frames the rose skyscraper that dominates downtown.

20130811-_MG_9787

From here, we head north on 99E to the northeast section of the city. The industrial character gives way to a neighborhood of mixed residential houses and small stores. It here that BPOW took place at Cymaspace. You can read the first part of my report covering the workshops here. The second half, which will cover the evening concerts, will be published soon. In the meantime, we at CatSynth recommend enjoying a beer, of which there was no shortage in any neighborhood of the city.

Report from BPOW!!! Part 1: The Workshops

It’s been a little over a week since the Battery Powered Orchestra Workshop (BPOW!!!) occurred in Portland. Today we look back at the workshops, which were in many ways the central components of weekend.

During the Saturday morning session, I attended a workshop on electronic textiles hosted by Cat Poole of Cacophonous Creations. The skill was to learn how to use conductive thread to embed both light and controls into clothing for future performances. But for the workshop, the task was to simply sew an LED and its associated circuit onto a dinosaur patch:

Of course, we at CatSynth approve of Cacophonous Creations’ chat noir logo! As for the task itself, the biggest challenges related to general sewing and laying out elements to properly fit (at least for someone with little sewing experience beyond repairing buttons). But I got through the threading of the circuit. It would be great to incorporate something like this into costuming for future performances.

In the afternoon, I attended a session presented by Steve Harmon of Synthrotek. It centered around DIY electronics and the ubiquitous 555 integrated circuit. But that then merely building an Atari Punk Console with a 555, we stepped it up with Synthrotek’s 4093 NAND Synthesizer.

The 4093 includes three square waves, based on a dual 556 integrated circuit. I was quite intent to complete it and be able to use it for my performance that evening. The soldering of the components went quite smoothly – it helps to both see other people soldering and to have access to a good iron. It was a quite a rewarding moment when the synth was complete and making sound.

My only disappointment was the pots not quite fitting and ending up a bit lopsided. But it worked great in the performance and will certainly be used again in the future. The additional confidence on soldering will also be valuable for future projects.

Additional workshops in the afternoon included an introduction and demonstration of modular synthesizers by Jeph Nor. He demystified modular for a general audience by presenting the fundaments (oscillators, filters, amplifiers) and adding additional elements.

Attending all the workshops on Saturday would have been impossible, especially if one wanted to complete the associated tasks. In particular, I was also interested in the Raspberry Pi which was presented by Edward Sharp.


Sunday’s workshop sessions opened with a demonstration of “squishy circuits”. It turns out that homemade play-doh is quite a good conductor of electricity, and can be used to quickly prototype circuit ideas. It also serves as a very accessible medium for introducing principles of electronics to children.

We also got to see other non-traditional conductive media including ink and paint that can be used to integrate electronics into artwork without the use of wires.

Then everyone scattered for an electronics scavenger hunt to find electronic toys and various media to use in projects during the afternoon. The participants reconvened later in the day and got to work.

Our host Travis Feldman of Molecule Synth hacked the interior of an Atari console with both audio and video modifications, attaching it to a Moog pedal.

Other creations included a circuit-bent toy keytar and a tactile surface used to control audio and video on a laptop.

Overall, the workshops at BPOW were a rewarding experience. In addition to new inspiration and a few new skills, I liked seeing the wide variety of interests and disciplines that others brought to creative DIY electronics for music, video and performance art. If the event does recur next year, it will be interesting to see how technologies and the skills of participants have further evolved.

In addition to the workshops, BPOW also featured performances in the evening. We will look at those in a subsequent article.

Feline welcome to Portland

My trip to Portland for BPOW!!! (the Battery Powered Orchestra Workshop) is over and it’s now time to reflect and report for the blog. Overall, this trip very much in line with the things I write about on CatSynth: electronic music, synthesizers, mathematics, urban landscape, photography, architecture, and even cats. Indeed, I know things were off to a good start when I arrived on Friday night and was immediately greeted by this cat:

It turns out this is Athena, one of the cats that lives with Travis Feldman, creator of the Molecule Synth and the host of BPOW!!!.

Look for a few more BPOW- and Portland-related posts on these pages in the coming days.
