The Ginger Bug

I brew my own Ginger Ale.

I started doing this, I think, in February 2008. Melissa had bought a book called Wild Fermentation, which was about using bacterial/yeast cultures to brew drinks and make food through fermentation. I’ve made over a dozen batches, and although I’m still improving on my recipe, it tastes pretty good!

My Ginger Ale recipe is essentially three food ingredients + the micro-organism culture.

  • Ginger Root (grated)
  • Lemon (sometimes lime also, and I’m experimenting with other flavor additives)
  • Sugar (white)

That’s it.

The carbonation comes from the fermentation of sugar, via the Wild Yeast. This is the same kind of fermentation process that brewers use to make ethanol (drinking alcohol) although this particular process / yeast culture does not produce a substantial amount of alcohol. (If there is any, it is barely noticeable, and largely depends on how long you let it ferment). The main by-product is carbonation (CO2) and awesome. Read the rest of this entry »

School’s Out!

Yesterday, around 6pm, I finished my last project for one of my classes, meaning that I am now officially done for this semester.

Cholesterol It’s been one helluva semester – first time I’ve done a full-time schedule (12 credit hours) in a few years. Compound that with a baby, and the fact that three of the courses were 300-level courses, and you’ve got a formula for disaster!

This semester I had four classes:

  • Organic Chemistry I (Chem 341, Lecture only)
  • Distributed Computing (Info 320)
  • Information Technology for Management (IIM 300)
  • Linear Data Structures (CompSci 243)

By far, Organic Chem was the hardest of all of them, and I successfully pulled off a B+ in that class. While I wouldn’t have minded an A-grade, I am completely happy with a high B. Distributed Computing & Linear Data structures were both somewhat difficult — in the former I had to learn the Python scripting language on the fly (I had never used it before), which was very frustrating. In the latter, I learned Java, a really awesome object-oriented programming language. The hardest part about that class though was learning the running times for all the algorithms. O(n^2) and O(n log n) and O(2^n), it was a lot of memorization that I only half-did.

The IT for management class was basically a discussion only course. Every class, people would present topics and we all would discuss them. It was pretty interesting — it definitely made the book more entertaining.

In other development, I am now double-majoring: My Bachelor’s degree will be a General Studies degree (or as my wifey calls it, a “degree in nothing”), and I will also be getting an A.S. in Chemistry. I’m considering a minor in Biology as well. I would major in it, but I would be stuck in classes for at least another 2 or 3 years minimum waiting for the classes I need to cycle in.

I saw the degree requirements for the Biotechnology program and became very envious. Genetics? Cell biology? Sign me up! It’s unfortunate it would take me too long to complete it. I suppose I can look into that for my graduate program?

Next semester’s classload, also full-time, is:

  • Organic Chemistry II (Lecture & Lab)
  • Intro to Biology (a pre-req for pretty much every other bio course)
  • Chemistry Topics: Protein Synthesis

Protein Synthesis should be neat – it’s my Chemistry professor that teaches it, and he’s a neat guy. He said we’ll all pick a protein and learn how to artificially create it from other base chemicals and whatnot. It’s strictly lab and should be a light workload compared to the other courses. (fingers crossed)

But for now, I’m going to enjoy a well-deserved break from school.

All your Photos are Belong to Us!

The darkroom is officially operational. Yes yes, you can all touch my hand, it’s ok.

No seriously. I got my chemicals early last week, and I stopped by Wal*Mart on Saturday to get the last of the items I needed to make my kitchen and bathroom lightight enough to do development.
I’ve got an Omega 600 B/W enlarger, a digital exposure timer, various trays, tongs, jugs, etc., a fireball safelight, film reel and tank for developing 35 or 110 film, a print washer, contact sheet printer, etc. it’s all good!

For all you out there who are wanting to build your own DIY darkroom in-house, but aren’t sure how to do it, maybe this can help you.
