Eye Update

I had my one week check in with the eye doctor today. He says my eyes have healed up and I can wear my contacts again. Woot! I’ll be able to see on vacation next week!
There’s a new kind of contact for my condition from SynergEyes for my problem. There is a big waiting list to get the diagnostic kite (whatever that is) so that I can be fitted. Not one to wait patiently, I called up Synergeyes and simply asked for them to send the kit to my doctor. They were helpful and are going to call him directly and see what can be done to speed things up.
Who knows if it will help, but if you don’t ask, you never know.

Out of commission

I knew this day would come sometime. After wearing my contacts for 18+ hours a day, everyday, my eyes have finally rebelled and decided not to cooperate any more.
Bright light had been causing me pain and I finally went to the eye doctor yesterday. My eyes have been injured a bit a nd need time to heal. What that means is no contacts for a week or until everything is healed up.
Due to my condition, keratoconus, this is a big deal. The condition does more than just make me nearsighted, it creates a smearing of what I see. Kinda like permanent double vision.
Special contacts basically give me 20/20 vision by correcting for the myopia and the optical bending that causes the smears. Most people wouldn’t know that I’m legally blind without my contacts. Without my contacts, I need to hold things about six inches from my face to have any chance to read it. Even then, I need to squint to see anything. I do have glasses, but they can’t correct for the smearing or fully for the near-sightedness. As a result, the glasses extend my reading range out another foot or so.
To write this on the computer, I need to lean far forward and increase the font size on the computer pretty high. Spending more than 45 minutes or so trying to read or use the computer guarantees a headache and sore eyes from squinting.
While this sucks and all, I have it good compared to some people and their eye problems. There are many people that never get a chance to see well at all. In that respect, I feel very lucky that I get to see normally most of the time. Of all the maladies that people suffer, I got off easy compared to many.
So what does it mean? It means I can’t drive or really work. Work involves a lot of reading and computer work. I can’t watch TV, it’s all a blur, even with my glasses on. So while my eyes heal, I basically need to walk around with my glasses off and do nothing.
Too top it all off, the dog chewed off the end of my glasses where they rest on your eyes, so I need to go out and get new frames for the lenses.
So I will see you all in a bit. Until then, do good work.

Public Speaking

Tonight I will be speaking to SMPTE Hollywood about digital media stuff. They spelled my name wrong, but here’s the panel I’ll be on.
Specifically I’ll be talking about “practical issues involved with creating portable media from traditional digital media workflows – transcoding content to the right format as well as metadata, XML conversion, DRM, storage and network/transport”. Thrilling stuff folks!
If you a television turbo-geek, please come heckle.
Warning: The SMPTE web site has a very 1999 design feel to it, so any creative types or designers should be wary, lest your eyes bleed. I’m not kidding, it would toss Jason Kottke and Khoi Vin into a epileptic fits if they ever saw the site.

More coffee options

After our nice find of Java Juice as instant coffee, Michele was on the look out for other options. While shopping at the 99 Ranch Market (an Asian supermarket in LA), she found a box of Casa Coffee.


Sure enough it’s another way brew a single cup of coffee for those of us that are coffee machine challenged.

Basically, it’s a single use drip coffee packet. You rip off the top and place it in the cup. The Casa Coffee people call it a ‘flying bag’ due to the wings on the outside that hold the coffee packet in place.

Pouring the water in was a bit troublesome. It didn’t work so well trying to use the hot water dispenser. I assume they intend you to use a teapot.

Once the water was in the coffee got one pass though the grounds and into the cup. In theory, it works just like a standard drip coffee maker.

Once the water it through, you lift the ‘wings’ and toss the used coffee packet away.
Too bad the coffee didn’t taste too good. Maybe they didn’t use good beans to start, or maybe I didn’t let it steep right, but the coffee was weak and tasted a bit stale. The mouth feel was wrong, missing that essential oil that just barely is seen on fresh brewed coffee. It would do in a pinch, but I prefer even the powdered instant more.
I gave it a second try the next day. I poured the water in a bit too fast and the grounds overflowed the filter and went into my cup. I spent the next five minutes trying to get the floating grounds out of the cup. Falling at that, I put in extra sugar and drank it down anyways.
I have to give props to Casa Coffee for a neat idea,but they probably need a one way filter system that prevents overflow and better beans. By the way, be sure to check out the impressive Casa Coffee wallpaper!

How to ventilate your computer

Last weekend, the hard drive in our media server died. This sucks, but is not the end of the world, we had backups. This is the second time the hard drive in the media server has died. My best guess is that this is due to excessive heat.
To prevent further losses, I’ve replaced the hard drive with a pair of hard drives in a RAID set. A RAID is basically telling two hard drives to act as one. If one fails, you have the other. I also bought an external hard drive to do even more backups.
But I need to address the heat issues. Michele is insistent that the covers stay on the computer. So, the easy method, leaving the sides off, is right out.
That meant using forced air blown through the case. I had a ultra-quiet Cooler Master fan and a grill for another project I never got around to doing.


So I had to figure out to mount this fan on the inside of the case. It had to mount on one of the side panels with a grill on the outside to protect from the fan and cover the cut-out.

After getting a good idea where the fan would fit, I laid the grill on the outside to make sure I could mark the drill and cut-out lines well.

I drew the lines and checked them 3 times. My father always says, “Measure twice, cut once.” and he’s right. If I messed up the outer case, it not like I can run to the hardware store for another one.

Next I drilled the screw holes. That allowed me to keep checking on the cut-out as they are the point of reference. Note the scrap lumber underneath to get a clean hole as I drill through.

Now a pilot hole for the nibbler was drilled near the where I needed the edge of the cut-out.
What’s a nibbler you ask? Well, it’s a special tool for cutting out bits of metal. Bascially takes little bites out of metal. Mine is tiny and only takes about 1/8″ by 1/4″ bites out of aluminum or thin steel. Good for precision work.

Once the hole there, I can place the nibbler inside it and start. You can see how I can track the line to nibble by just watching the top follow the cut line.

Again, be very careful not to make a mistake, I repeatedly compared the grill to the hole I was cutting out.

This is the hole only a few nibbles before completion. You can see a few of the cut-out bits on the ground. You need to be sure to vacuum these up. They are sharp and can cut feet easily, whether they human or canine.

Here is the fan in place, behind the side panel with the grill ready to get screwed together.

Once in place, the fan is ready to go.

Here is the grill in place as well. Looks pretty good, eh?

The power is plugged into the fan, and I’m ready to close up the case.

Last step was checking for Michele’s approval. She thought it looked nice as well.
Project complete.
If you want to try it yourself, it’s fairly simple. The keys are having the right stuff (fan, grill, and a nibbler) and taking your time. Rushing the nibbling or trying to use a makeshift tool like a file instead will to disaster.

What the…

In the last week, I’ve gotten a half dozen emails about advertising on Cruftbox and three different headhunters called me to offer jobs.
Wha? I am simply not that in demand. My unhealthy fascination with junk food alone should scare most people away.
What happened? Did someone post me on a milk carton or a bathroom wall?

Tube Radio

Last weekend, we helped our friends with their garage sale. They advertised and set up the sale. We brought over our crap, err, our fine pre-owned items and helped out with the sale and watching the kids.
In the middle of everything was this fantastic item.


What’s so special about this radio? Looks like a simple AM radio to most, but this ia actually a tube radio.

Sure enough, this is a 5 vacuum tube model AM radio from the early 60s. An explanation is in order. Back in the early days of electronics, vacuum tubes we the key to all modern innovations from radio and TV to amplification of signals.
Like the sound of electric guitars and the speed of microwave ovens? Thank vacuum tubes.
People in their 30s and older will likely remember TV commercial that told you to when your TV broke, you could bring the tubes from your TV for easy replacement. They had special kiosks at the supermarkets for the testing of the tubes.
Vacuum tubes have mainly been replaced by transistors in almost all uses. A few niche markets remain, like broadcasting and audio enthusiasts, but by in large it’s a forgotten technology. The ‘tube sound’ or ‘tube amp’ refers to the use of vacuum tubes in audio systems. Some people swear by the tube sound, but I can’t hear much of a difference between it and a good solid state (transistor) amplifier.
I had a brief education in tubes (or valves as the rest of the world calls them) in college in the late eighties. But they still fascinate me. There’s a brisk market on ebay for tube radios, but they aren’t worth a lot.
This radio was from the last generation of vacuum tube based radios that were meant to compete with the new transistor based radio arriving on the scene. Transistor radios were smaller and ran off of battery power, unlike the larger tube radios than needed to plug into the wall.

The radio works great. I adjusted the dial, listened to a baseball game on it, and was in heaven.
Best of course is that the schematic diagram and tube callout is on the bottom, ensuring that I can keep this running forever.
