Or you can do it with Opto22 boards from eBay - 24 port boards go real
cheap and you can install one of 4 modules for AC or DC

Subject: Re: [Owfs-developers] 1 Wire Switch & Solid State Relay
Donald,
I used an opto-isolated relay board from www.futurlec.com
(http://www.futurlec.com/Opto_Relay_4.shtml) and attached four DS2405
chips to it. Here is a link to the manual for the board:
http://www.picbasic.it/ETTe/ET-OPTO%20RELAY4%20Manual.pdf
And here is some text I sent to someone else describing what I did:
If you have the manual that comes with the relay board you'll find that
to be helpful. Also the data sheet for the DS2405 (from Maxim's web
site). I just soldered a terminal block (3 terminals) and the four
DS2405 chips to the empty area on the relay board. The terminal block
is for connecting GND, +5V, and 1-wire data to the board. If you
arrange the chips one directly above the other in every other row you
can just use solder bridges to connect all of the GND pins together and
then all of the 1Wire pins together. Refer to my crude diagram below.
The DS2405 chips are arranged with the flat side towards the top of the
diagram (so the pins are 3-2-1 from left to right).
....[] <-- +5V terminal
..__[] <-- 1-wire data terminal
..|_[] <-- GND terminal

.ooo.. <-- DS2405
..||..
.ooo.. <-- DS2405
..||..
.ooo.. <-- DS2405

.ooo.. <-- DS2405
......
I removed one of the connectors from the opposite end of the board and,
using the manual as a reference, soldered wires from the +5V and GND
terminals I added, and from pin3 of each DS2405, all to the appropriate
spots where the connector had been. The connector I removed was a
single row connector with 6 pins (I think). It was the one that the
included cable does not fit on. It doesn't matter which connector you
use, since they all carry the same signals. Just refer to the manual
for the pinout.

Can anyone point me to some materials on using the DS2405 with a
solid state relay. Basically what I am trying to do is control some
lights.
