Things I've Built

Decimal Clock

A Clock that keeps time in decimal fractions of a day. Made before microcontrollers--all TTL. My mom made a stained glass box. It works out that 15 minutes is pretty close to 1% of a day.

Hi Bill, thank you for liking the one transistor flipflop, https://hackaday.io/project/112126-one-transistor-flipflop ! And thank you for your inspirational One Transistor Latch !

  Are you sure? yes | no

I like your blog, there is a lot of good stuff there.

  Are you sure? yes | no

Bill Smith wrote 10/24/2015 at 20:35 • point

Thanks!  I haven't checked the sources that i used 8 or 9 years ago to see if they still exist.    I've got 6 vendors so far in my list

  Are you sure? yes | no

Saw your comment about PCB fabs. Check out PCBWay. Fast and cheap, plus they can do 4-mil trace and space. I used them for the CAT board because none of the other low-cost fabs could get below 5-mil.

  Are you sure? yes | no
