For All Things Fran Bookmark this page and check
back every day for something new!
Welcome to my daily
update page! What does this mean? This is the place where
I will post things of interest, stuff about science, the purely entertaining,
corsetry, my side projects both past and present, and any other thing that
I feel like sharing. Enjoy!

Enough about ME - This
Expeditions recovered two flown Apollo F-1 engines from the ocean floor
- 14,000 feet below the surface - with amazing custom made robotic submarines.
It is as yet unknown which flight this first Saturn stage came from, but
detailed analysis of the engine parts and their serial numbers could reveal
that in the near future.

- Here is my new discrete minimalized mosfet overvoltage protection circuit
breadboarded in two stages; open point-to-point and hybrid surface mount.
Linear circuits can behave differently as you condense the layout and change
part lots due to changes in inductance, capacitance, and parts tolerance,
so it is important to build and test each stage of development. You
can be very surprised when a tweak is needed.

Another Lab Day for
me - and a keen observer of my blog spotted one of my DIY tools in my messy
desk photo last week - It is a hold-down for SMD soldering. Ever
try to hand solder SOT sized parts? This makes it easy! I used
a tool that is commonly called a 'dental stimulator' which you can get
at any pharmacy - it has a soft rubber point on the tip and these tips
are replaceable, you can get sets of them to keep around the lab, and with
a small rubber band stretched across a couple of screws in a block of heavy
scrap hardwood you have an adjustable SMD hold down arm! The hold
down pressure is set by the rubber band, and the entire thing is very precisely
adjustable and quite stable. The rubber point will grip and hold
any small part while you solder it. It has proven a very handy tool
for these pesky little buggers (as Dave from EEVBlog
would aptly say!)

Feline speed bump -

My three part series
on PCB manufacturing got noticed on several blogs over this past week,
Magazine posted my older Shredcam project. It has been a bit
of a media blitz lately for my Youtube channel and science blog to be sure.
I am on hiatus from the videos for the time being while I catch up on corset
work and finish some upcoming projects for Maker Faire. Did I mention
that I don't have any spare time these days?

Sorry for so few postings
but much 'life stuff' going on for Fran. Everyone I am aware of in
the vlogging and blogging world is on twitter - so I hear anyway - but
the thought of such a thing scares the bejesus out of me. I think
that any attempt on my part to enter that crazy world would mean the end
of my functional life. So, you get this - my ridiculous occasional
update page - whomever you are that read the Daily Updates. And why
are you reading this anyway? Don't you have something else you need

This is part two of my Do-It-Yourself
Printed Circuit Board Trilogy!

This is the first in my 3-part
vlog mini-series on high quality PCB manufacturing, and introduction to
my "make your own LVDC logic devices" project. In these vlogs
I will show the specialized tools and equipment that you will need to make
your own high quality PCB's from scratch, with step by step demonstrations
of each stage - from rendering and checking the artwork, to applying the
resist to copper clap boards, to etching, to drilling the PCB's, to component
placement and soldering, and finally to defluxing and finishing.
