Switching? Close

Some parts arrived today!


Looking to see about switching power to some Pi’s via some kind of web-usable API.  I’m using 74HC255’s to drive the relays – Arudino writes 8-bits at a time into them.  And then 74HC244’s to read the current state of the latches so that the PI’s will cleanly survive an arduino reboot..   Once that’s sorted, I can build a management API that something like WHMCS can talk to 😉


Managed to get an Arduino talking to it, but not quite correctly.  Must have fudged something. Will look at it again later 🙂
