“No Dino” stickers

Got em! On my J1772 inlet “gas tank” cover. corbin


Cyr Wheel Skinning: Not all tubing is the same!

I’ve ordered a few different types of skin for my cyr wheels. On one wheel, it has pieces from two different batches and kinds.This has shown me that one is much better! Both are 1.5″ x 1 7/8″ PVC tubing. This one, Canada K091008 wears much faster: This one, K120816 wears MUCH slower, and will last a lot longer: Both I got from PWMall.com. I’m not sure which is which!! Darn it. Here’s the two I bought..and the site doesn’t have these numbers on it: PVC Cyr wheel Tubing – Kuri Tec® K050 Series All Purpose Non-Reinforced Clear Vinyl Tubing... [read more]

LED Cyr Wheel v1 Problems

Some of the problems with my original LED cyr wheel: 1. LEDs are dying, from me stepping on them. I took one of the bad sections apart, and it seems to be because some solder connections break (such as for the resistor). I can solder them back together, but it is not worth the time to reskin/glue it. I need to figure out a better way to protect them. Here you can see a resistor that fell off when I removed the protective skin. I think some hard epoxy on plain bare LED strips might “cement” them in place really... [read more]

Half Dome at Night 12-25-2013. About 10 minute exposure. I was freezing cold that night; it was about 28F.


LED Notes / LED Cyr Wheel v2

I’m investigating LEDs for another LED cyr wheel (v2). Here is my first LED Cyr wheel and a video. I figure I’ll just make my notes on my blog for others to benefit. Goals: Individually addressable LEDs, so I can do cool patterns At least as many LEDs as my first wheel, but possibly twice as many (a strip on each side), which was my original plan Built in battery charger and batteries (Lithium ion) Easy to access way of reprogramming (i.e.: USB port) Extras: Accelerometer for basing patterns on speed Live touch strips, for dynamically changing the LEDs while...

Sunset from El Capitan, Yosemite 12-25-2013. 5 exposures taken with the Canon 5D.


Adhesives

I’m investigating adhesives, and ways I can bond the plastic PVC tubing on cyr wheels back together. I want to cut the plastic tubing, and embed LEDs under it for some cool effects. For my first LED cyr wheel, I used high temp hot glue gun glue; that worked “okay”, but it is fairly easy to pull apart. I also need a better way of protecting the LEDs, as some are dying. First I’m going to try RH Products “HH-66 vinyl cement“, which is easy to find from numerous resellers (including ebay). The website for it says it will bond... [read more]


Oil pan fixed on my Harley

I have an old Harley, and it has leaked oil for quite a while. I finally decided to do some maintenance on the old bike and took off the oil pan and stripped the paint off. The tank had a leak on the left tab; the tab was welded on, but vibrations created a hairline crack on it. I filled it up with brass brazing rods and also repaired a crack in the bottom center mount. Then painted it powder coat red and put it back together. I also added some new rear shocks, changed the oil, new oil filter,... [read more]


No Fossil Fuels Sticker

I finally cleaned up my “no fossil fuels” sticker for EVs! I just ordered a few stickers (8) from StickerYou — http://www.stickeryou.com/ — the place has a decent website, but they have a terrible security flaw of emailing you your signup password back in plain text! That is just a huge security “no no” and I can’t believe companies do this. The order page also failed for me like 5 times; I had to finally use paypal to get it to work (which also took three tries!). We’ll see what the quality of the stickers looks like; unfortunately, they only... [read more]


Bathroom almost done!

Shower door installed (I paid someone to measure and install it…it was much easier than me doing it myself): Cabinet doors and hardware installed. Waiting for the counter top to be fabricated…


Geared Hub troubles

I have several KH/Schlumpf geared unicycle hubs. They allow me to have two different speeds, and really have been a game changer for unicycling. One of my older hubs started to have bearing failure, causing it to rock back and forth in the wheel. This problem was fixed in later versions of the hubs, but I didn’t want to get another one and the hub is way out of warranty. But by chance I happened to have a set of good bearings (long story), so sometime last year I opened up the hub and replaced the bearings. No problem! I... [read more]


Adding a disc brake to an older KH24 mountain unicycle

I have an older KH 24 mountain unicycle that doesn’t have the disc brake mount on it. During my Switzerland/Italy tour in the summer of 2012 I used a D-brake adapter (from unicycle.com) and KH spirit cranks to go with a disc brake on my KH36. Scott Wilton told me I could machine the back of a D-brake adapter to make it work with the KH/Schlumpf geared hub: He warned me that hard braking might bend it, so I was always paranoid to really grab the brake hard while on the tour. After the tour, I got a new KH36... [read more]


Bathroom remodel: Shower tile

I’ve been rather slow to update my blog. It is mainly for myself to remember what I did. After I finished the shower pan, I painted this red waterproofing membrane on the areas that might be exposed to leaking; in particular, it was required for the two niches I made, and also the window sill. I had extra, so I painted it around: After that was done, I started tiling the wall! This was my first tile job *ever* and it wasn’t easy getting the hang of it. My neighbor Mark loaned me his tile saw, which helped greatly in... [read more]
