What’s that thing about time and money?

After spending about 12 hours painstakingly soldering three prototype LED boards to illuminate the tank, my tally was as follows: One completely soldered board of RGB LED lights, 80% of which I accidentally burned out when I carelessly tested an electrical connection and bypassed a necessary resistor One completely soldered board of RGB LED lights […]

Amp build is complete

Yesterday John and I had a marathon session to build and test all 4 amplifiers. We added larger thermistors after the rectifiers so that the current draw doesn’t blow the fuse. John also added some lines into the program to allow us to turn on the magnets from the computer, thereby also limiting our current […]

New logo!

Our friend Beth made us a new logo.  It’s awesome. We’re going to get T-shirts made.  Leave a comment if you want one!

Final magnet design, (almost) final amp design

This weekend, in a marathon session of effort, we were able to create the almost final versions of both the magnets and the amplifiers for each one.  This video shows the 6 ohm magnet we made with the new winder; the new amp that we made (greatly simplified design), and a temporary stand.  You can […]

Stand build continues

Finally there’s a part of this project that isn’t entirely new for me.  We’ve been winding test magnets, soldering prototypes and fooling around with arduino code for so long that I’m getting used to all three but for the first time in a while, I’m doing something that I not only have done before, but […]

I thought I was a big Tesla fan until…

… I found out that the guy who writes The Oatmeal is also a fan. So I can’t be called a “big fan” in comparison to this awesome screed.

Tank stand buildout

We built the stand for the tank last night. Goal was to make something that could support the 550 pounds of water in the tank when full but also not be so heavy and unwieldy that one person couldn’t lift it and move it around. We used my favorite light construction lumber: the 2 x […]
