Photography: Train Station Adjacent, Venice

Train Station Adjacent, Venice From Venice, Italy. 07-24-2012. 5 exposures taken with the Canon 5D.

Photography: Phelders, Italy

Phelders, Italy I work up yesterday morning (July 17th, 2012) and opened the door to our little deck on the second story floor of the hotel we were staying in. The sun was shining brightly in the right half of the sky and the shadows on the rocks and country side were just amazing. Normally shooting into the sun produces terrible pictures, but with HDR you can tweak the shadows and highlights to get just the right look.

Photography: Old Building

Old Building The trip from Phelders Italy to St Leonardo was mostly downhill, so I stuck my 5D in my camelback. I took this picture while riding down the road. It turns out our “short day” from Phelders to St Leonardo was a “normal” day with 800m of climbing up to where our hotel really was located. But it was awesome, and worth it!

Glaicial Views From the top of Mänlichen, Switzerland which is above Grindelwald.

Photography: Schloss in Nauders

Schloss in Nauders Castles need to look menacing, and this picture definitely seems to have captured the menacing look. The slight saturation gives it a dark and ominous feel. With more color, it looks more vibrant and alive: Schloss in Nauders v2 I love castles, and the unicycle ride from Nauders, Austria to Silandro, Italy was a four castle day! (Well, we probably passed more, but I only consider a certain look to be a true castle).

Photography: Nauders, Austria

Nauders, Austria This is one of my favorite photos so far. It is an HDR from 5 exposures taken with the Canon 5D Mark III. I sat on top of the hill for a while and enjoyed just being alone and looking at the beautiful town and gigantic mountains. The sun striking down was amazing. The photo is not photoshopped, and was only combined and adjusted in Photomatix. The gang spent two nights in Nauders, Austria. The climb up from Switzerland consisted of a ton of switchbacks up a steep hill, and then a slight descent down into Nauders. We... [read more]

Nathan’s Unicycle

Nathan’s Unicycle July 2012. Nathan’s yellow KH 36 geared unicycle. 7 exposure HDR.

Alps Unicyclists

There are three mad unicyclists on the mini-Swiss unicycle tour I’m doing. Me, Scott and Nathan Hoover. Unfortunately, I don’t have a good picture of Nathan yet, but here’s a few cool ones. Myself (Corbin) taken by Scott Wilton and processed by me to do a cool black and white HDR: Scott Wilton, in living color by my unicycle. Also an HDR out of 5 exposures, with Scott selected to tone down any “ghosting” that occurred from movement.

Swiss Wildflowers

Swiss Wildflowers From Preda, Switzerland. July 10, 2012. Today was 60km of unicycling from Chur to Preda. The 60km wasn’t that bad, but the 1700 meters of climbing was quite a bit. Tomorrow will continue the climbing up Albula Pass. When I got to Preda, it rained lightly and I took some pictures of flowers.

Photography: Down to Andermatt

Down to Andermatt Today is a rest day, and it is a little wet out but the sun is trying to poke out over the mountains. We are staying at the Basecamp Andermatt

Handegg to Andermatt

Still unicycling! We rode from Handegg to Andermatt today. Only 32 miles but we went over Furka pass and Grimsel Pass; that was a bit of climbing! We were averaging like 5mph up the hills, and cruising down at 22-23mph. Along Furka pass is the Belvedere stop with a big glacier. Spot the unicycle in the photo below.

Grindelwald to Handegg

Today we rode “only” 30 miles, but it was almost all uphill from Grindelwald to Handegg Switzerland. I didn’t bring the DSLR with me, since it was raining on and off. The start of the climb was like riding up into a cloud. Here’s another great picture I took yesterday. It is an HDR from 5 exposures using the Canon 5D mark III and 24-70mm lens. Switzerland July 5th 2012 – Grindelwald, Switzerland. How about a map of where we rode today?

Grund Grindelwald Rest Day

On the Swiss Uni Tour today is a rest day, which meant hiking and photography! B&W Mountains July 5th 2012 – Grund (lower part) of Grindelwald, Switzerland. Black and White HDR from 5 exposures. We took the gondola up to the top of Manlichen and hiked around a tiny bit. My legs are a bit tired from riding yesterday. I really love this area of the Swiss Alps. It is one of my favorite places in the world. I visited nearby this area 12 years ago and I always really loved it. I’m really glad that coming back I have... [read more]

Grindelwald Sights

Grindelwald Sights July 5th 2012 – Grindelwald, Switzerland – Canon 5D Mark III I’m traveling through Switzerland via Unicycle. The “gang” doing this Swiss Uni Tour consists of myself, Nathan Hoover and Scott Wilton all on geared 36″ unicycles. Geoff F. and Grace Fleming are on bikes. My dad and his wife Karen are driving a support car with all our stuff. We flew into Zurich on Saturday (arriving Sunday morning) and took a train to Konstanze, Germany to rent a car. It is much cheaper in Germany to rent a car, and lodging is way cheaper there when compared... [read more]

CVT (Continuously Variable Transmission) Unicycle

My friend Justin up in Vancouver brought this invention down for the Maker Faire a month or so ago. He custom made a frame and attached a CVT NuVinci hub to the unicycle. Awesome. Video of me riding it:

Plug Bug: Home J1772 EVSE Charging Station

I now have a J1772 EVSE Charging Station at home. My friend Ken Adelman gave me an old Avcon charger that he had saved from the dumpster. I bought a J1772 plug from and wired it up. Here’s the inside of it. The board was a little loose, so I glued it down. I unplugged the 3 inlet wires; red and black are 120v each, and the green is ground. I then screwed in plug’s wires to the terminal screws and attached the low voltage signal wire to the spot where it said to do it. It all works... [read more]

Roue Cyr Point of View v1

I got a cheap “go pro” like camera from online not too long ago. My friend Jason was getting one and said I should get one too (so I did!). Here it is hacked onto my cyr wheel in a loose way. I need to make a better mount to get it to be firmer and give a better view of the spinner .

Rob’s Ride, 10th Anniversary

Over 10 years ago my friend Rob started a 20 mile unicycle ride throughout Santa Cruz. It starts down by the beach Boardwalk, rides up to UCSC campus, does some mild off road trails through Wilder park, and then finally ends with a nice cruise along “West Cliff” drive. Heck, it is even so popular that Ken made a website dedicated to it: Rob, and a group of my other uni-friends, do it nearly every Sunday. A month or so ago marked the 10th anniversary. So I rode with my Canon 5D and did some live-riding filming.

Plug Bug: It breaks, I fix it.

Last weekend my car suddenly shut off all power while driving home. It happened again this morning right as I was going to drive away. I could jiggle the key and it would come back on…but this seemed hokey, and unsafe (especially after my last stall on highway 17 due to a huge pothole and my inertia switch flipping). I realized the short was in the wires heading into the ignition switch, as I could jiggle them and it would turn the car on and off. I took the steering column apart and realized it was this little thing that... [read more]

Plug Bug: The Inertia Switch works

The electric bug has an inertia switch in the case of an accident. It looks like this: It is designed to cut the 12v system to the rear of my car, which turns off the controller and high power contactors, thus cutting power to the motor controller in the event of an accident. It turns out I discovered it works. They are doing a lot of work on “highway 17” to Santa Cruz and I hit a really big pothole a few weeks ago. It jerked the car enough to make it stop, which was bad, as highway 17 is... [read more]

Plug Bug: Blower install on the motor

The bug’s motor runs pretty hot on hot days. You can’t keep your hand on it for more than a brief instant. I have measured the temperature with an infrared thermometer, but of course, right now I forget the values. I know that it was well below the values for the motor’s casing temperature, but more than one person has told me that running the motor cooler will prolong its life. So, I finally decided to install a blower. evsource has this electric motor blower kit for $448, which is quite pricey. I figured out they use a rather weak... [read more]

Plug Bug: Broken brake…

…well, problems come in pairs. I changed my front brake pads about about 8600 miles; they wore away quickly! I didn’t change the rear, as they weren’t as bad as the front. I checked the new front ones at 15,000 miles and they are doing great. I had looked at the rear but only on one side and without taking the wheel off. They looked okay, so I wasn’t going to do them yet. However, the rear brakes started making a horrible noise last Friday. So today I decided to take the brakes apart and drop in the new pads... [read more]

Plug Bug: Running again!

An update to the last post: The bug is running again! George, from Netgain motors, suggested seeing if the motor had excessive vibration. When I ran it at 12volts it seemed to hum pretty fine, so I put the car back together. It took a while, but I was running again by last Wednesday. I can’t really tell if the motor has any excessive vibration; it sounds a little different when I put in the clutch, but it doesn’t sound out of balance. So, I’m going to go with it! Oh, and the little pieces that came out of the... [read more]

Plug Bug: 15,000 miles then a breakdown

The Bug has over 15,000 pure electric miles on it! The past ~14,000 have been relatively painless. I’ve had to do a few tweaks along the way, but nothing major. Unfortunately, that changed last friday. I was getting into the carpool lane on Highway 85 southbound and accelerating hard. Then all of a sudden the motor was free spinning and not moving the car and making a bit of noise. I put in the clutch, as it seemed to make less noise that way, and pulled over to the side. I had to get towed home. I figured the transmission... [read more]


Proteas I sure love these flowers. They are amazing. Taken at UCSC Arboretum, April 22, 2012. Canon 5D Mark III.
