Thermo Nicolet IR200 Spectrometer investigation
Requires a custom power brick, multiple pins. Could not find power specifications. Power bricks do not seem to be available.
Laser was removed from this unit. This is a HeNe laser used “provies the reference signal for triggering data collections and measuring the stroke of the moving mirror.”
Dessicant spot indicates that the dessicant was exhausted. Dessicant appears to be a standard pack. Recharged dessicant in 250F oven for three hours. I’ll try to preserve the optics, I may be able to reuse them.
Requires ENCOMPASS or OMNIC software. I was able to find an OMNIC iso. Untested.
“The interferometer window in your spectrometer is made of KRS-5…” KRS-5 is thallium bromoiodide (TlBr-TlI). KRs-5 (TlBr-TlI) is a gorgeous red crystal commonly used for attenuated total reflection prisms for IR spectroscopy. It is also used as an infrared transmission window in gas and liquid sample cells used with FTIR spectrophotometers in place of Potassium Bromide (KBr) or Cesium Iodide (CsI) for analysis of aqueous samples that would attack KBr or CsI optics. It has a wide transmission range and is virtually insoluble in water. It is a useful alternative to AgCl since it is not photo-sensitive and for ATR applications it will transmit well beyond the 18 micron useful range of ZnSe.

After the 2000 ‘hanging chad’ election, the Election Commission report concluded that about 10% of votes are never counted or miss-counted. The Republican President and House didn’t much care, threw a few billion at the states some counties replaced the punch card machines w/ electronic voting machines. It made things worse. The election results are still untrustworthy, but in many places there’s no paper record to check but there is a poorly designed and poorly secured software program counting the votes. And yet worse, these voting machine companies are all private, and keep their software a secret, so there is no way to audit the software or check the election results. In the *rare* cases where security researchers have inspected the software and computerized voting machines, they have always proved easy to break into and subvert. Same with the centralized websites counting and recording the votes. Complete failure of democracy.

The company builds on research findings several years ago that if the bloodstreams of young and old mice are connected together, it seems to rejuvenate the older ones. … In a 2015 study, for example, scientists at Novartis found that GDF11 levels do not fall with age and that the protein actually inhibits rather than promotes muscle regeneration.

Gosh, the earnest talk by Republicans on the paramount importance of scrupulous by-the-book handling of classified information was just a show for the TV cameras and gullible Republican votes.
“More than 130 political appointees working in the Executive Office of the President did not have permanent security clearances as of November 2017, including the president’s daughter, son-in-law and his top legal counsel, according to internal White House documents obtained by NBC News.” link
And for most of these folks, ‘does not have’ means the FBI checked them out and won’t approve clearance because they are a security risk. Some of these guys are known to have worked for hostile foreign powers.
