I've uploaded some photos of the Datron 10 volt cell and reference board, as requested by a few members. I've kept them full-resolution so you can see fine detail. But, that means they are about 3 mb each. The schematics for the cell board I previously posted are also still on the FTP site.
DatronCell.jpg is an image of the entire cell board. The reference board is piggybacked on it. Note the thermal shield around the LTZ1000, and the completely shielded sections on the board. Those contain the digital circuitry. The cell board itself goes into a shielded enclosure along with the other three cells and the output buffer amp. DatronLTZCloseup.jpg is exactly that, a closeup of the LTZ with thermal shield removed. The interesting detail here is the mounting. Note the cutouts on the board to provide thermal isolation. This board is also very thin; I didn't measure it, but it's on the order of 0.5 - 1 mm thick. DatronRefCloseup.jpg is a closeup image of the rest of the reference board. The ref board is permanently soldered in place on the cell board, so I can't show the back of it. The ftp login is: ftp ftp.quackers.net login: f...@quackers.net password: (none required) Or, directly from a browser. I know this works for Firefox, I haven't tried it with anything else: ftp://f...@quackers.net:f...@ftp.quackers.net/ Some of you are also waiting for the schematic for the LTZ board itself; I'm recreating it now (since I lost it) and will post when ready. -- Bill Ezell ---------- They said 'Windows or better' so I used Linux. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
