Landing Gear Light Relay

Very cool and thanks loads..

I can't wait to see the final. I'm learning a lot of new skills lately, but it would have taken me weeks to MAYBE figure out some relay. I hope I can return the favor one day. Since I've been part hunting, maybe I could help you there.

Here is the final schematic. This version has open collector outputs, which lets you drive any kind of load for the Up, Down and Transition outputs (up to 500ma each).

If you have questions about building this or hooking it up let me know. If you know electronics and see mistakes or have suggestions for improvement please let me know.

This circuit is pretty easy to build on perf or proto board but if there is enough interest I could do a run of printed circuit boards. These would cost $10US plus postage to your location. PM me if you are interested.

I am interested in your landing gear light relay board. How do I go about buying one ?

This is the first request so I have never had any PCBs made (it costs around $60 per run of 10-20 boards). I could possibly do a one-off build for you on protoboard, check your email.

I would be very interested as well. Andre.nordheim@hotmail.com

This is an ancient thread but a user contacted me with problems he was having with the schematic and I wanted to post an updated version. After a little more testing I will also be ordering some PCBs if anyone is interested (PM me). Once they are ordered I will have an idea on cost, but something like $10 (USD). Attached is an updated schematic as well as some renderings I made of the proposed PCB (shown populated but only the bare PCB will be available for purchase).

Happy landings

The gear indication is "true" as it monitors each wheel position so the "stagger" is what is actually taking place.
The gear commands are a true "up" and "down" and not a toggle.
There is no need to wire up what you don't want.
The card it'self is only about $25 and available at lots of good hobby / robotics / electronic shops

Cool project, thanks for sharing.

Thanks William but also thanks to you for your great website.
It's on my bookmark list from months and months ago. :)
Lots of info there and your site is one of the very few that supplies source code for other people to use. VERY rare now-a-days. Well done . !! :)

A lot of people haven't heard of the Arduino cards and being so cheap and versatile (and available world-wide) I just though I would fire that in. It may help.(or not ?)

Thanks again William ,,, Jim
