Anamorphic 3D Image With Photoshop

I had seen this done in the past and wanted to give it a try myself. This is essentially a 2D printed image that is manipulated in such a way that when viewed an a specific angle, it looks “3D”, or simply like actual object. I started with a picture I took of a large […]

Nalgene aspirator vacuum pump

Wanting to do some experimenting in a vacuum, I sought out a low-cost vacuum pump. I found all kinds, but by far the least expensive, and best-bang-for-the-buck, was an aspirator pump. These can be run on either air or water. The one I chose will use water. I got a Thermo Scientific Nalgene water aspirator […]

Cryogenics: The Cryogenic Treatment of Materials

Cryogenics is the science that deals with the study of very low temperatures. This is not to be confused with cryonics, or the preservation of humans by freezing them. Need your brake rotor to last 3 times as long? Perhaps you’re a machinist and you’d like to get several hundred more holes out of your […]

SVG – Click and Drag/Move Object With Mouse/Cursor

I’m working with SVG graphics and JavaScript right now. I was trying to find out how to do something seemingly very simple… click and drag an object to move it. What I found, however, was very little. The few examples I found either relied on a 3rd party libraries, or had examples using standard JS […]

Setting up a freshwater aquarium

I’m working on setting up a new 29 gallon freshwater aquarium. Right now I’m cycling the tank, or more specifically, I’m performing a fishless nitrogen cycle. I’ve added about 4.4ml of a 10% ammonium solution to reach a concentration of 4ppm in the tank. This should be adequate to start building of the good bacteria […]

My first meteorite

Just received my first meteorite today! I was first intrigued by meteorites on my last visit to the Smithsonium in Washington D.C. a couple years ago. They’ve got a large and impressive collection of them. The cross sections of meteorites are very interesting as well. They’ve got a “crystal” metal structure unlike anything on earth. […]

Audio tone frequency generator – online

I needed to be able to generate some frequency tones for project involving measuring vibrations. I just need to be able to generate a range of tones at specified frequencies. I found some nice online tools that did just that, so implemented my own here: http://nuclearprojects.com/tone/ It’s easy to use… just type in the frequency […]
