USSTCC Customer Success Video!
A friend and customer of mine successfully completed his second SSTC using my USSTCC controller and design specs. His newest coil is a full bridge SSTC running off rectified and filtered 120v mains, capable of unlimited duty at more than 1.6kW CW or Interru...

Improved Arduino Ethernet WebServer Example
Just a quick one today because the need has arisen; I had tons of issues getting the Arduino's Ethernet Shield to work, and it turned out to all be because of the shitty coding in the example sketch. So, I did what any one would do once they realized the er...

Sigurthr's Electrical Engineering Calculator
Sometime in 2014 I decided that I was tired of using online calculators for various common electrical engineering related equations. It was time consuming to use and annoying to keep track of. I shortly decided that I would write up a simple CLI program to ...

The Little UV Sensor That Couldn't... Adafruit's SI1145
So, I'll be rather quick on this, since this little bit of silicon doesn't really deserve more. I am extremely disappointed in Adafruit for endorsing such a piece of crap, but I suppose I can't expect them to actually thoroughly test every bit of tech they ...

So you've made yourself a sweet Half Bridge SSTC or DRSSTC, and now you want to increase your coil's performance by moving to a Full Bridge. Adding the extra transistors, diodes, resistors, and doing all the additional layout is really the hard part, but I ...

Arduino and ATTiny85 SSTC Interrupter - Version 3!
While doing the programming for the V2.0 revision I decided that I really wanted to try my hand at making an interrupter all on my own, without relying on someone else's code as a basis. While it sounds like an easy task it really is difficult because of th...

ATTiny85 SSTC Interrupter - Version 2.0
I finally got around to revising the code and schematic for my original SSTC interrupter. I do want to point out that this is still heavily based on Gao (loneoceans)'s code and he really deserves a great deal of credit for it. See his website here: http://w...

Arduino - True Binary Digital Clock
So, nearly a year ago I posted this: http://sigurthrenterprises.blogspot.com/2015/01/arduino-binary-clock-serial-output.html It basically is the intent statement for the binary clock I was developing and a teaser sketch. I fully developed my clock shortly a...

New X-Ray Cassettes Came In... New Radiographs to see!
The two x-ray cassettes I ordered came in, and my research rang true; both are green emission and far better quality and performance than the old Cromex blue I had initially used. I got one X-Sight Regular X-Omat and one Lanex Fine X-Omat, both by Kodak. It...
