[time-nuts] Frequency counter recommendation

[Mark Sims]

A much simpler solution is to dedicate a $20 "obsolete" laptop to the Tbolt.  I use a 200 MHz Compaq Armada with 1024x768 screen.  I have also run Heather on a 90 MHz Fujitsu Milan with a 640x480 passive matrix screen.  

For bonus points,  tap off the internal laptop CDROM power connections (and possibly an internal -12V line) and power the Tbolt from that (you may want to filter the wazoo out of it).  Voila,  battery backed up Tbolt.  I know of one person who has an ancient,  steam powered laptop that had enough room inside it to mount the Tbolt circuit board totally inside the machine.
-----------------Just as an example, in my spare time I'm trying to port the great Lady
Heather to the "mini STM32":

so my thunderbolts will not be more depending on an always turned-on PC.
