Status of efforts to develop a cryogenic micro-calorimeter as a beta spectrometer for 17 keV neutrino searches is given. Experimental requirements are derived. Using NTD germanium thermometry, adequate detector performance (1.5 keV resolution at a base temperature of 130 mK) is demonstrated. Exploration of source deposition and encapsulation is underway.
