The Place For All Things Fran

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!

Major Ironing....

Enough about ME - This week Bezos 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.

Proto-typin' - 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 - Missy's home position at the top of the stairs.

My three part series on PCB manufacturing got noticed on several blogs over this past week, including Hackaday and Adafriut, and Make 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 to do?

Drafting time.

And now, the conclusion.....  Drill!

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.
