Thanks everyone. That should be sufficient for me to try playing with the diodes.

Thank you!

I've come across an array of pump laser diodes (IPG brand, PLD-6-4) wired in series with a 3-terminal component I can't identity. I suspect it is a voltage or current regulator, but can't seem to Google-up any info on it. Markings are "PHP 21N0GLT PHm0501E2". TO-220 package, red and black wires...

Thank you all for the information. I should have noticed off the bat that it's output was DC. After finding it, my original idea was to build a Jacob's ladder, but <2mA of output current seems too low.

Can someone help me better understand the specs for this old transformer I found? I'm confused why the input and output power see to differ greatly (115V*1.2A ~140W while 40,000V*2mA~ 80W). Also, the fuse rating is unclear to me. Does that mean 1 and 2/10 amp?

Thanks. If temperatures exceed the commercial range for me, I'll have bigger problems than the amp :-)

Thanks. The virtual ground circuit is a neat idea, but I'd like to avoid the complexity if possible.

I'm building an Arduino voltage logger that includes an op-amp (OP27G) as a buffer on the input. Since I'd like to be able to measure voltages all the way down to zero, I want to power the amp with a bipolar supply. My initial thought was to build the rail-splitter below so I wouldn't have to...

I have tried, for example: x = [11/2 11/2 11/2 13/2 13/2]'; % F y = [9/2 11/2 13/2 11/2 13/2]'; % Fprime z = [0.117 0.114 0.110 0.156 0.151]'; ft = fittype('HyperfineShiftFunction( [x, y], Aprime, Bprime, offset )'); f = fit( [x, y], z, ft ) Where...

I have five data points (x,y,z), with two independent variables (x,y), and have written a function in a separate file z = f(x,y,A,B,C), with three undetermined constants (A,B,C). How can I use a Matlab fitting program to try and determine the constants? I've written a fit function before where...

You're right. I was confusing the nuclear g-factor of a proton with the nuclear g-factor of an atom.

Looking at the Wikipedia page for the Lande g-factor, I'm a bit confused. I thought that g_I\approx5.585, that of the proton, but then there is the line saying that https://en.wikipedia.org/wiki/Land%C3%A9_g-factor It makes sense that the nuclear and Bohr magnetons would differ by the mass...

Thanks so much. I was wanting to remove them because they seemed to be cluttering the references page. I might just add a note about them, and keep them in place since you're right, they could be useful.

Thanks. I think it's in the package files too. I'm going to dig through the assorted files in the folder while I wait to see if the author responds.

I think it is defined by the thesis template that I'm using, not Zotero. I've tried changing bibliography styles within the same template, and the problem remains. Using Zotero and bibtex with other templates dies not display the issue. Tried looking at the thesis style in a text editor, but...
