FSMs
IF you don't have extra$$ try these sources:
Polaroid one-step cams have a nice one inside --shaped like Penn.
or tombstone shape-fairly thin so easy to cut ,,,(I gently scratch the back side) I only pay $1 or less ...
inside ALSO a nice small DC motor great for other projects.
like spyrograph-/Tunnel effect and Liquid sky--but no batt there as it is part of the 'film pack'
There are some FSMs inside Kasio/BenQ etc PJs aside from the dichro mirrors.
Messy and time consuming--I use a high quality ('regular') mirror
and use paint remover( I wear rubber gloves)
takes more than one coat-- I use a soft old toothbrush at first---then an old 'waterpick') it will not scratch--
I got a good deal from Fred 'Surplus Shed) on Kodak 4X6 inch somewhat thick FSMs
good size as -is for bounce and turning uses.
For a monster size FSM watch for rear projector TVs-being thrown away every where.
A cheap one will have a light weight non glass mirror (mylar MYB_) and very big--I kept one of those--the others have a glass FSM.
It is hung over my bed with note on the corner--" Objects in mirror are BIGGER
than they appear''
Seems that the older TVs had glass mirrors--or MYB the better brands--also some HUGE lenses (3) some of those are 'liquid' filled.... MYB oil.
Testing for losses is easy meter twice -- second time meter the turned dot.
ps
DTR used to sell Kaiso/BenQ PJs--w/ all optics. lenses and FSMs.plus heatsinks and four nifty fans
He may still have some whole (sans diodes) Kasio PJs.. I got 8 of them from Jordan 'long' time ago..
Thrift shops often throw away flat bed (and combo printer/scanner) scanners - at least one or as many as 4 long narrow high(ish) quality FSMs inside most a tad thick but in some the short and wider one is the best-easy to cut -- thinner. Sometimes PC repair shops end up with some-
between FSMs, CDRom 'disc' mirrors and free 'pulled' 18650s these shops are a goldmine.
Hundreds of Thousands of these scanner end up in the land fills.
