For the electronic geeks! A Guru lid open / fan off timer

Recommended Posts

Here are my plans (till the nice folks at Guru build the accessory timer):

- Multi-mode timer kit - operating in mode 4 - ( http://www.electronics123.com/s.nl/it.A/id.375/.f ) (specs - http://electronics123.net/amazon/datasheet/k141.pdf )

- Mercury or non-mercury tilt switch ( http://www.philmore-datak.com/Page%20149.pdf )

- 9v battery and battery clip - BC-100 ( http://www.philmore-datak.com/EDS27.pdf ) Ended up not using - pulled power from Guru instead

- small enclosure to house device w/ mount

- 5.5mm od; 2.5mm id plugs /w leads and panel mount jacks ( http://www.philmore-datak.com/Page%2062.pdf )

This would allow you to plug your fan into this box, then plug the cord coming out of this box into your fan output from the guru. The device operates off the 9v battery (or power split from Guru plug). It would energize normally closed relay causing contacts to open when lid is lifted (tilt switch activates), thus killing power to fan. When lid is closed, tilt switch deactivates, relay is still energized and timing circuit begins. When timing circuit times out, relay de-energizes and normally closed circuit allows power back to fan. The timer used in this circuit is fully adjustable to allow for whatever time delay is needed for your cooker to equalize before allowing the fan to turn back on.

In lieu of tilt switch, any kind of reed or snap action lever switch could work depending on your mounting situation. ( http://www.philmore-datak.com/Page%20138.pdf )

Please, any suggestions or comments welcome.

You suck Curly, you know that! I went through the trouble of moving the thread to another section (since you cannot post to the links section) and you post no comment!!! :twisted: I love it - that was funny - but you still suck! :P I should have known better than to think you had something useful to post - haha! :roll:

Re: Mounting a switch..

I could have the metal boys make a lil' bracket for the tilting switch back on the hinge. Keep your wires away from the working area..

As I said, I'm actually in the happiness business

:lol::lol::lol:

See, that is what I love about this place!! 8) That is exactly what I was looking at doing on the back hinge too!

:shock:you'll :shock:

Hard to believe anyone is north of you. Real Southerners know how to use y'all :P

Damn, I did not even notice - but I usually do use 'y'all'! Well, your north of me also; so now that finger goes to you now too (I'll just turn slightly north-west to catch you)! :shock::P

Now back on topic! An Update!

Well, just a little update on the project. It works like a champ! I ended up buying everything from http://www.partsexpress.com/ and http://www.electronics123.com/s.nl/it.A ... ategory=44 . While I am sure when the Guru folks makes one it will probably be cheaper, smaller and nicer looking, this one will work in the mean time. A few changes I made; I ended up using a car alarm tilt switch (which is encased and mountable), so I was able to keep it external to the timer box and therefore able to mount the timer box on the fan with the controller. I placed the tilt switch on a plug so it can be more permanently mounted on the grill hinge or lid and just plugs and unplugs for use. Since the timer box is right next to the controller, I also decided just to split the power in from the controller instead of using the battery. I am also adding a green LED to the normally closed side of the relay to get an indication when the relay is active (lid open tilt switch active or currently timing).

As soon as I get everything mounted in the box I will take some pics!

FYI, there are some companies out there that sell the timer kit already soldered for a few bucks more for those who cannot or do not want to solder.

Off timer too!

Another thing I did not think about; for those whose Guru does not have an off timer, just change the timing mode on this little timer (mode 6 or add a tilt bypass switch and use mode 1) and it would cut your grill off automatically at whatever time interval you set (timer operates from 1 sec to over 42 hours with only a 15 second deviation at max time)!

First Pics!

Well, the mount is still curing and I have not made up my labels, but I could not resist posting some pics! I know it looks huge in these pics but it is only 1x2x4 and will mount perfectly on the backside of my ProCom's controller. Then you run the tilt switch to whatever location you like via plug/cable/clip. Oh yeah, it's a little messy inside the box, but who looks in there anyway! Once you set your equalization time, you should rarely have to go in it anyway.

This is the tiny tilt switch with an aligator clip mounted to it for easy placement anywhere you need it!
