Tips for Surviving in Real Life

tips for surviving in real life

In 2009 I had a predisposition for making poor decisions, and because of this I ended up becoming homeless. I was married at the time (no children but two dogs,) when I talk “homeless,” I mean the whole shebang!

Sleeping on the concrete, finding whatever nook or cranny, building or wooded area we could find to settle in with our animals. Our only belongings we had left were a sleeping bag, comforter, a bag of clothes and a bottle of vodka.

1nm Resolution Test Successful 8-Bit CCD Detector TCD1304DG

Well, this may be the ugliest test platform I have ever made but it sure worked, I had to modify my circuit board @ R8 going to pin#3 at the opamp [LM324], by running a bypass from the C9 [200pf cap,] to pin#3 @ the LM324, some strange ground problem I can’t quite figure out yet from manually placing the components on the PCB design circuit in DesignSpark.

TCD1304 8 Bit Driver Noise Reduction Design Changes

I am confident in it’s performance, even @ 8 bits, I did learn a few things though about working with CCD’s, one is, thermal noise, yeah, even with NO power its still there, and on the breadboard it has little room for any air circulation underneath, so I had to compensate for this “dark current” by taking at least 5 dark frames and comparing the frame with the least amount pixel depth and then averaging the other frames together at their higher RMS #’s and subtracting that from the low pixel numbered frame and that gave me a pretty good representation of the most stable dark current values.

Fast 8 Bit Driver Circuit

So I have decided to go ahead and build the fast 8 bit drive instead because I already know that it works flawlessly, and can still read all 3648 pixels from the CCD, It reads 3694 pixels, but the first 30 and the last 16 are dark reference or dummy pixels and are discarded.

I have already drawn the schematic using Design Spark and will post the gerber files so you can order your own PCB and build it. I am including the BOM also.

My Three Stray Cats

This is my little daughter cat, Tiny, I saved her as a small kitten here at City Point Hopewell Virginia (down by the appomattox river) I had to have a damaged eye of her’s removed but she doesn’t seen to mind much.
