Yes, I will allow the children to pour the 2000-degree liquid metal.
The BuzzBox
2022-06-14 12:13 by Ian
As an object lesson in electricity, my youngest boy and I built a high Wattage transformer box with a trigger. It is named BuzzBox because while operating under full load, it emits that 60Hz buzz that usually means a fire is about to start.

Enough visitors to my home have taken pictures of my workbench to convince me to put pictures and descriptions of things online.
Secondary battery and isolator installation
2013-11-26 08:29 by Ian
I bought a 250A battery isolator on ebay for $70, but when the thing arrived, I realized that I had a serious problem on my hands. The thing was too long to fit in any convenient mounting location. So I had to get creative.
Metalcraft (PC Case)

For the past eight years, I’ve been limping along on my 2Gz P4a. I finally built myself a new PC, and quickly found that as the hardware has become better, the cases have gone one of two ways: Either cheap 1/16” steel rattletraps that cost $40, or Xbox hueg l33t towers full of lights and windows.
No thank you. I’ll roll my own.

This is my solution to the problem of reliable sub-zero cooling.
