Fun with Dust-Off…

Tuesday, August 21st, 2007

Dust-off canister

No, not that kind of fun – I’m talking about fun with endothermic reactions!

You see – Dust-Off isn’t really compressed air (pressurized Nitrogen is pretty boring) but is in fact liquid difluoroethane. So what happens when you release a liquid with a boiling point well below that of room temperature (-24.9 °C)?

Lets find out:
Calulations

You get a reaction that will absorb an awful lot of energy from it’s surroundings (you can freeze stuff).

Getting more to the point- around here, in the summer, I come across a fair bunch of house spiders and, while I don’t mind them outdoors, can’t have them wandering around indoors. The problem is that they can be pretty tough to catch (especially the small ones) and mashing them makes a mess (especially the big ones). However, with the help of the aforementioned fluorocarbon, dealing with insects is a breeze.

All you need to do is give the can a good shake, tilt sideways and aim and fire. If you do things correctly the nozzle (moistened by shaking) will produce a directed spray of very fine difluoroethane droplets that, due to the their large surface area, vaporize rapidly – making the immediate surroundings very cool.

Bonus: on a humid day, your very likely to see frost form from the spray!

It’s all about the Brackets, Baby!

Obj-C hands picture

With C4[1] starting tomorrow (which I, sadly, won’t be at). It seems apropos that I put out my graphical rendering of Rentzsch’s Obj-C sign from C4[0]. There you are!

The Crankflip Tee

Sunday, July 8th, 2007

As I mentioned before I’m now a unicyclist of sorts and, as I should post about soon, I also have a fetish for unique, swanky tshirts- the combination of which brought me to, over the past month or so, immerse myself in the world of professional printing. The result of which I present to you now:

Unicycle Tshirt Picture

I’m calling it my Crankflip Tee, and it’s been my first hands-on experience with custom tees – how exciting!

Getting more to the point, now that I’ve completed the design I’m getting ready to get it professionally screen printed in a week or two. Since I’ve already had a few inquiries on the shirts from inside and outside the unicyclist community I’ve set up a page for ordering them here.

Over the next few weeks I hope to get much wiser to the ways of low-volume, custom printing. If the experience proves itself to be worthwhile you can expect to see a few more designs to make their way onto quality, sweatshop-free cotton in the not too distant future.

By way of Laughing Squid I found a groovy Simpson’s avator creator (part of the Simpson’s movie promo site). Who knew that an appropriately themed paper doll could be so fun!

Looks like I’m all ready for my guest appearance. Now to work on that getting famous part…

Brisk Green Ice Tea

Friday, July 6th, 2007

Lipton Green Ice Tea can This is a posting about me and my taste for “interesting” soft drinks. In addition to the usual suspects (like Jones sodas and Bawls) I also have a fondness for the fly-by-night varieties from major producers as well.

In the past I’ve hoarded dnL and on the off-occasion I eat at a Taco Bell I’m sure to get Baja-Blast from the fountain. Most recently I stumbled on Lipton’s Apple Flavored Green Tea at WWDC last month.

It tastes a lot like I would guess sour apple Jolly Ranchers in liquid form would taste like (and fructose levels commensurate with that). MMmm, give it a try – it’s some good stuff.

Adventures Beyond the Ultraworld

Adventures Beyond the Ultraworld album art Yesterday while I was in Berkeley (headed to unicycle basketball, natch) I stopped by Rasputin Music.

Rasputin music is an awesome chain of music stores in the Bay Area. They’re a little freaky (named after the dead siberian witch doctor…) but they carry a bunch of my music which, in the US, is pretty impressive. They have a great selection of Dance/Trance/Electronica – which in my book gets them mad props.

Anyways, out there in downtown Berkeley I was able to get a hold of the Orb’s Adventures Beyond the Ultraworld, one of the first and most important ambient albums from the 90′s. And it wasn’t any watered-down American version either, it was the original UK 110min two-disc release – so exciting!
