OK so you might know who i am or you might not, I’m not on lumenlab alot but I love my projector, and I hope to make a new one right away, but being a college student kind of puts a hurt on the money flow. But over the years I have been doing my research because I have always wanted to be able to control things from my computer. What I have come up with a 6 relay controller. It works really great, and I have found a program called Relais Timer, it allows you to control the outputs on the port. I will do my best to try and explain my process and how I did it, and hopefully if you want you will be able to build your own. I also have posted most of what I have done already on my projector page. Well lets get started, first I want to explain how it works. Basically it works by using the ports 5 volt output on pins 2, 3, 4, 5, 6, 7, 8, and all the pins 18 to 25 as a ground. You must also supply a 5 volt voltage for the IC, I just used the USB port, if you cut open a USB cable red is positive, black is negative (obvious) the white and green cables are data. The heart of this controller is the 74LS367A, it’s basically a buffer, to help protect the port. After that comes a fairly basic relay driver.

Here is the basic schematic for the design.

These are the parts that i orderd from jameco:

Jameco # Description
108599 RESISTOR NET,16PIN,1K OHM, 1
139977 RELAY,DIP,DPDT,5VDC,2A CONT 6
99398 CONNECTOR,5mm TERM BLK(3)RTAG 6
38236 TRANSISTOR,2N2222A,NPN,GP 6

47562 IC,74LS367 1
37402 SOCKET,IC,16PIN,MACHINE TOOLED 2

I believe it came up to like $32 CAD

Here is the link to the software i use

This is a picture of my finished board. I like to use wire wrap method it seems to work really good for me.

Here is another picture of my box except im missing one of the recipicals at the moment.

One thing i should point out is that there are some recipicals, or at least the ones i have, that you will have to cut a small piece of conecting material, to allow you to control all six outlets, otherwise you will be hooking up two relays to one wire and it just wont work. The circled part on these next pictures should show you what i mean. But be careful because you only want to cut on side not both if you cut both you might have to run extra wires. I just cut the black/red (positive side), i just lef the white (negative) side alone.

Carls Electronics (eletronickits.com) sells a few kits similar to this. The cost is a bit more, but you can get them preassembled as well. I cant begin to count how many goofy little projects I've done with boards similar to the one that you've made. Good work!
