Neat stereo effects

Posted at age 29.

I was listening to Reality by Oliver Koletzki with my headphones when I thought I accidentally switched the audio to my large speakers. Alan was in the room and indicated he heard nothing, so I was momentarily very confused! Then I rewound the track and found the same thing happen again, at which point I realized the track was either post processed or the microphone physically moved so the sound would seem to have moved behind. I couldn’t find any web pages mentioning this track, hence this blog, probably only for my future reference!

Reefkeeping: the beginning

Posted at age 28.

Alan started keeping a saltwater aquarium earlier this year, and since I’ve been living with it for the past two months, I’ve become fascinated with reefkeeping. I am planning to start my own once I move to my next apartment in January. This leaves me plenty of time to obsessively research the many aspects of marine life.

Iron filings and a strong magnet

Posted at age 28.

Back in April, I ordered a large magnet to have some fun. I intended to make some sort of art project using pieces of metal suspended by thin strings, but before I got that far, the magnet ended up as a centerpiece on our dining table for most of the year.

First tardigrade sighting!

Posted at age 28.

As explained in the first entry, I bought a microscope mostly so I could look for tardigrades, aka water bears, and hopefully make lovely videos of them. Within hours of getting my scope set up, I managed to find some!

Isolated tardigrade: My first attempt at finding tardigrades and putting them on a slide, using an OMAX M837ZL microscope. This is using a 40X objective and a 14MP camera at the smallest video setting, 1024x822, for faster frame rate.

First impressions of OMAX M837ZL series microscope

Posted at age 28.

The microscope I bought arrived, and I spent a day getting familiar with it and the lenses. I was generally pleased, but ended up buying a bunch of new objectives and condensers to see if I could get better images. This post is regarding the initial purchase except the images at the end featuring the darkfield condenser.

Seeking OMAX M837ZL series microscope manual

Posted at age 28.

It took me a while to locate the manual for my new microscope. I was not surprised to have trouble since the lone Amazon review warned of no manual being provided and a broken link, but it was more difficult than I thought it would be to find the manual online.

My OMAX M837ZL microscope came with a broken CD, but luckily I was still able to get the files off.

I bought a microscope

Posted at age 28.

As an early birthday present to myself, I bought a microscope despite many other priorities. I’ve spent a few days using it over the past two weeks, and while I have mixed feelings, I don’t regret the purchase.

While waiting for the microscope to be delivered, I searched for moss in the park that overlooks my house from above.

OMAX software and micrometer sample images

Posted at age 28.

I’ve been getting acquainted with my new microscope and its digital camera software. I initially decided to buy a microscope based mostly on the USB camera resolution finally exceeding a few megapixels without costing thousands of dollars. After these tests, it looks like I may end up not using the USB camera much after all, due to difficulty getting the colors right. Thankfully I decided to try a Nikon SLR adapter, as photos through that look much better!

Birds measure San Francisco radiation today

Posted at age 27.

After an hourlong run and finishing my leftover tostada salad from The Little Chihuahua this afternoon, I noticed out the kitchen window a helicopter flying fairly low over the Pacific Heights area of San Francisco. I didn’t think much of it till I heard it again, and again.
