Excellent.

I think I've finally caught up with everyone that was supposed to get one of these modules. The second version seems to be working well.

If anyone else wants one of these just send me a PM with your address. If anyone still has the old 3-wire design and would like to swap it out let me know as well.

Ken
You have mail.

I always have mail.

None of it seems to be from you though.

Ken, my check is now in the mail. Thanks! You ROCK!!

Hmm, well, not sure how I missed this post, but didn't find it in search until today. (weird.)

I was thinking about adding a circuit to the rear wiper as well... but on my 16 hour long drive down to New orleans last week, the entire time it rained, from moderate to hellaceous downpour... so i had some time to think as i dodged soccer moms driving in the thick rain while still talking on their cellphones...

If the front wiper delay could be tied to the rear wiper, that would work great for me. Don't have a wiring guide, but would it be as simple as running a relay off the front wiper wiring and interrupting a rear wiper wire?

I watched my driving in the rain, and ya know, the rear on my X gets about as nasty as the windshield does at the same time.. so tying the front to back makes sense to me.

Not knowing the wiring on the 02's... what do ya think?

(PS - I'm a technogeek and love the PIC idea too! But if it's this simple I'd have a hard time going with the controller.

It's possible, but don't forget a way to get the rear washer to work as well. A couple of things you'll need to know:

1) The wiper motors get one side pulled to ground to run them. The same thing goes for the 2 washer pumps. The + sides are tied to 12V.

2) The delay module for the front wipers is attached to the front wiper motor on the outside of the firewall.

Nuf said... I think I'll save up for one of your modules instead.

I guess the current design makes sense from Nissan's point of view... If I had to make as many XTerras as they do, removing extra expense is always a top priority.

Thanks for the info Ken - you rule!

The wiper delay modules have taken off in a way I never anticipated. I never expected to make more than a few but the 50th module shipped today. Because of its popularity, the module and Poor Boy Engineering must now change.

The module will get a real printed circuit board instead of the vector board used in the present modules. It's the only way I can make them fast enough. It will also get a newer microcontroller (PIC12F675). Nobody will see a difference in the look or performance.

The price of the module will rise to $25 on 12/21/02. I didn't mind making almost nothing on them when I thought there would only be 10 of the things ever made.

The biggest change is that Poor Boy Engineering will become a real company, registered in Connecticut. Sooner or later the state will figure out what I'm doing and I don't want to end up in jail with a boyfriend named Bubba.

Web based, I'm assuming?? And let us know as soon as you have a web site set up so we can have a one-stop shop for all of the goodies you have!!!

Your module went out today. It was #50. Anyone who has already asked for one still gets 'em for $20.

It's always interesting to see how others have approached similar problems. During a rare free moment I disassembled the original Nissan front wiper delay module. Here are the guts:


It's a nice design but probably more complex than it needs to be. It looks like it will last as long as the rest of the truck if the relay holds up. Here is what some of the stuff is:

IC1 is the brains, a Microchip PIC16FR711. No doubt chosen for it's A/D converter but has way more pins than are needed here.

IC2 is a reset minotor for the micro. This is redundant, the PIC has most of this built-in.

IC3 is a voltage regulator

The blue thing is a 4 MHz ceramic resonator, the master clock.

The box with "3059 BC" on it is the relay that ultimately drives the motor.

Q1 is the transistor that allows the PIC to drive the relay coil.

I suggest that if Electroken's Xterra ever dies, everyone here chip in and buy him a new one.

Ken,

Check yuor e-mail, just sent you payment via PayPal for the wiper delay module. It looks great! Can't wait to install it! What other electrical mods do you have available for the 2002 Xterra?

Thanks,
Jim

I did Ken's mod and it was easy to do,especially from someoe like myself that isn't crafty with wiring at all...took me a total of maybe 15 minutes to do and that's with stopping to go back in the house to grab a beer..

But it works great and love having it on my truck,it certainly beats having ther rear wiper going constantly....

Nothing. Even the wiper delay was someone else's idea. Got any ideas for new widgets?

How about a Flux Capacitor?

Yeah Ken help me out with my foglights...

I wanna get them to stay on when I use my high beams...

Wreckerboy is going to mail me a couple of 2002 wiring diagrams including the fog light circuit. Once I get them it will be a snap to figure out.

The flux capacitor will take a bit more work...

Sounds good to me..Also I have a donor vehicle if you need one...*hint,hint*

How about and auto down feature for other windows? Instead of a 3 position switch like the driver window, we could use a switch where in one position, it would cause the driver door window buttons to act normally and in the other position they'd all be express down. Just a thought. I always wondered why they didn't make this feature for more than one window.

Any good aftermarket alarm window controller will give you this. Don't need an alarm if all you want is the one-touch.

DEI's is around 90.

In the switches or the remote?

Oops... missed your reply...

DEI's window controller is about $90 at best buy. It interfaces between the switch and motor, and reads the inputs from the switches, giving you one touch up and down. That's by itself.

If you hook up the ground-while-armed (used for starter kill relays, for example), the module will also roll up the windows.

If you also hook up a second channel ground input, you can either roll the windows down totally when disarmed, or crack them one inch within 20 seconds of arming.

You can insert the module between the drivers door switch and windows, but the passenger window switch will then be on the "motor side" of the wire, and passenger wont have one-touch control. If you run the passenger window wires over to the passenger door and tie the module in there, then passenger would also have one-touch.

It's a pain, and most people only connect everything in the drivers door... but it's an option.

I don't think there is a suitable ground-while-armed trigger outside the SMART entry module to use this with the factory system. You could use the ground-during-key-lock trigger wire from the front doors to roll them up (its a wire that tells the SMART module you locked the doors with a key). But who uses keys to get into an Xterra anymore?

If you want to discuss further, this should probably be a new thread.

The wiper delay module finally has a real PC board. After building 64 units on vector board I had enough. Just because it's built in a basement doesn't mean it has to look like it!



Hey Xterradon, see what you started?

Sorry about the crappy picture. It's difficult to get a good shot of a 1.3" X 1.6" object with a point-n-shoot camera.
