Tell us about yourself!
All that is old becomes new! Photo of my entry into the "Barney Oldfield Memorial Downhill Grand Prix" sponsored by Santa Clara University in 1973 in the Santa Cruz mountains. Yes, I did wear a helmet for the actual run!
Don't feel bad about being "long winded". A rational explanation of each choice lets the reader decide how well their goals align with yours and make appropriate personal choices. Very well done!
The UV5R is also programmable for the FRS (Family Radio System) frequencies. I have these in as well as local amatuer repeaters (I am licensed). There may be lots more folks out there with big box store handhelds than Hams.
Soldering at work is a breeze with a zoom microscope and teeny-tiny irons and tweezers. At home I have a standard adjustable temp Weller and a nice flip down Donegan Opti-Visor magnifying visor. If you can spring for the glass lenses, they are worth the money. The other thing I use is round wooded toothpicks and a block of beeswax. I have terrible luck with parts jumping out of tweezers, so I stroke one end of the toothpick lightly across the beeswax and I can pick up anything 0805 or smaller and transfer it to the board. Just roll the toothpick off the part and use the un-waxed in to push it around. Tweezers have a nasty habit of getting magnetized and dragging your tiny part away when you want to let go of it.
Where did you find the typewriter key caps?
Made something very similar, but I use it to top up the travel tube from a full sized tube at home before leaving. I think I've had the same travel tube for a couple of years. The plastic ones, rather than aluminum, can be refilled almost forever!
Excellent and very much more detailed than my terse reply (we agree). You do the community a service for your input!
Really can't be. No long, continuous fibers. Strength would be closer to particle board or masonite.
Not limited to purses! I have a felt sleeve for my Android tablet made by the same method. Elastic band closure.
Sort of. Earliest laser printers used either a Cadmium Sulfide drum (Canon patent) or Selenium drum (Xerox patent). HP licensed the Canon technology, but built most of their mechanics and all of their electronics.
Where have you found a phototransistor that can stand the 250V trigger voltage of a "high voltage" flash like my old Sunpac 411?
You might want to think of making a thin hot wire cutter to use in place of the laser. I've cut a number of polypropylene wing cores with stainless steel wire and a low voltage. high current hot wire.
Stainless steel safety wire works quite nicely. Used it to cut polypropylene wing cores for combat foamies for a couple of years.
