LimitlessLED: diychristmas.com is no good, they are only 120AC
Not true... I checked, and they are in fact 240V capable.
1A switching capability, basically just for low current christmas lights, not giving enough headroom for lightbulbs and switching other power supplies..
Agreed that these are low power... they were designed to be a cheap solution for low power requirements like Xmas lights. But 1A at 230V = 230W (depending on power factors and stuff like that). So enough capacity for a lightbulb or two, and maybe ten if they are LED or fluoro.
http://n7xgshop.net are more expensive than you think, and it just comes in many non-assembled parts. this is from their own website:
Yes, it is a kit, so you have to assemble it and solder it yourself. This shouldn't be beyond the average geek, IMHO.
Average Cost to build including board
$75.00 $75.00 $68.0 $70.00 $88.00 $50.00 $60.00 $78.00
I couldn't find those figures on their site. And I couldn't find a BOM for the 4-channel board. But I did find one for an 8-channel board. Total cost of components for 8 channels from Mouser (not the cheapest of suppliers) was $46. Leaving out the expensive RJ45 connector and terminal blocks (not needed in a hard-wired setup) took that down to $NZ$13.76. So I figure that components for a 4-channel board should be about $7, plus US$5 for the board itself, plus shipping. So I'd say I could build one for $15 plus an hour or two of my time.
