EFRATOM M100 and DiviBoard

Recently i’ve found some great codes from Tom Van Baak (Leapsecond) and use them  as frequency dividers. You can find the *.hex and *.asm  here I’ve burned some PIC 12F675 using a PIC programmer to have some  CMOS TTL  frequencies for  various applications  One of them was to use the M100, a great military Rubidium […]

Efratom M-100 : First View and Test

 What are we talking about? Today I’ll talk about this magnificent little device found on eBay : the  Efratom M-100.First of all, what is a Rubidium Frequency Standard?  It’s an atomic clock.Just in the 80-90 they were such  an expansive units! The working mechanism is fascinating. It uses the hyperfine transition of electrons in rubidium-87 atoms […]
