printer networked light control

[Andy] sent in his ‘Network Something‘ hack. For his proof of concept, he used a parallel port printer network adapter to create a set of network controllable LEDs. The virtual printer was implemented with a set of shift registers and a set of nand gates. (and a power regulator). Old print servers can be had pretty cheap – my HP $8 on ebay. Definitely an interesting way to get inexpensive network control of your projects.

Note: We’ll be making some server changes today and tomorrow, so comments will be offline for a bit. They’ll be back.
