I have been researching the whole RFID system for motorcycles and although I think I would probably move my ignition down under then tank or the seat this is an interesting set up.
Don't know how practical it would be if your phone dies but still a cool concept.

The solid state relay takes the very weak signal pulse from the RFID and turns it into something you can latch a standard 12v relay with. I tried to have the RFID latch a standard relay but it simply doesnt have enough power. So from the battery the power goes to the RFID. You swipe the 'key' it sends a positive pulse out. The solid state relay takes this and can do a number of things depending on how you set it up(can even have timer delays etc). Mine instantly latches on which I use to trip the HD relay for my power. If I swipe again it unlatches power and the HD relay opens and turns off my bike. Ill post video soon. My bike is done, but i haven taken good photos or video of it yet.

Thanks for bringing this to my attention. I'm definitely going to use this on my upcoming build. Have you had any issues with this set up?

Yes. And to answer the above. The RFID receiver does constantly pull a small amount of power because it is always searching for a keyfob. That said, if you are going to run your bike infrequently, install an inline toggle for the receiver. I did that on my CB. Kinda like a storage switch to keep the battery topped off.

I never even thought of this, such a sick idea. It goes perfectly with the "feel" I am shooting for with this build. Modern tech in a vintage wrapper. How long have you run this set up on your bike? Ever run into any problems with it? Is it waterproof, or do you have to seal it up? How does it handle the vibration of your jockey rocket?

Dyrden can you help me work out if this solution is possible for the RFID setup?
1. RFID triggers relay to activate ignition (on only)
2. Switch triggers relay off
I was thinking of using an LED switch on the triples that would illuminate when the ignition was on, and would trigger the relay to close if it was turned off.
That way there would be a clear indication if the bike was on, and no risk to turning it off again if the RFID was close to the antenna.

Latching relay makes all the difference. Most RFID systems with proximity actuation are not going to work unless you are very careful wher the tag and Rx are located.
You could also do it with a remote control to turn ignition on, starter and even light effects. Keep the remote in your pocket and as you walk up to the bike, click button A to turn on the neons or flashing strobes or whatever. Button B = ignition on and push C to start it. Just don't forget the steering lock or the disk lock or other mechanical anti theft devices.

Does the relay accept 2 inputs for switching on/off?
I was thinking tag would activate relay via on input which would in turn supply voltage to bike. Switch would be setup in line with ignition which could be setup to supply low voltage back to relay as a continuous off supply trigger.
Then relay is set to reset if this off voltage changes (when switch is turned off).

A latching relay will turn ON with one press of the button and OFF with a second push.
Push once and the relay connects. Push it a second time and the power is switched off.
I was trying to work out how to use a combination of NC and NO (Normally Closed and Normally Open) and not getting anywhere. I knew there was a type of relay that stayed in the new position without keeping power to it, but didn't know the term and it took me forever to find them - fortunately Dyrden saved us there.

It sounds like the relay can be setup to accept differing inputs to change the output stage too, hence my questions.
Just not sure if a relay exists that you can have 2 different inputs to separately control on/off, or even if its required for what I want to do?
Given a voltage would be supplied once the relay has been activated maybe I could combine the switch/tag so that the tag initiated the relay to turn on the ignition, the feedback low voltage from the switch would keep the relay activated until it was switched off, where the relay would return to normal. No need for a latching relay.
Thoughts?
Also does the input signal have to be low voltage? I would assume the tag/RFID is so matching it with the switch output should be fairly easy (or does it not matter and could I feed straight 12v back?)

Im ahead of you. The nut on my triple tree houses a stainless waterproof elevator switch, which is my momentary switch for the starter solenoid. This also has a green halo around it. The green halo is my neutral safety switch so the bike will only start in neutral. Im planning on getting some good photos this weekend so you can see what it looks like. So, I walk up, swipe my keyfob, the tail light comes on and if its neutral the green halo around the switch lights up. At that point open the petcock and press the button which trips my ford style solenoid sending power to my starter.
There are lots of possibilities and options when wiring relays and you can get creative. I took about 45 minutes one night and sketched my bike with the necessary wiring and figured things out on paper before I broke out the wire spools and connectors. I was also going to do a super basic angle trip switch for a little alarm. Something like, tip the bike up off its side stand when the keyfob hasnt been passed and set off a little horn. I was going to use a ball bearing activated switch from ebay for 5 bucks but I started running out of room to hide things on my bike.
Neevo,
I tried to have the reader/RFID trip a relay but the pulsed output while the keyfob is around is super low voltage and doesnt trip a standard 12v relay(I even tried 'high efficiency" relays but it didnt work) Thats why I used the solid state relay/switch. It can take this signal pulse and then acts like a regular relay. I then stepped that to a HD relay to act as my key on power. From there you can do what you want with the signal. I can swipe the bike off if I want, use a kill switch to cut power to the ignition or use the 'storage' switch to cut power to the relay. There might be a more elegant or simple solution than mine but this set up works well for my needs.

There's a couple of alternatives:

As far as I can tell, yes. They are pretty cool little boxes.
Heres my under tail in the testing phase:
Untitled by bailey_james62@ymail.com, on Flickr
The black box on top of the battery is the RFID reader. It also has a little red LED that lights up when you pass the key fob but I dont use it since my tail light lights up when my key fob is passed. You should note the distance from the pick up antenna(which is like 30 inches long or something) to the keyfob cant be more than 7 cm, which isnt far but it works through things like fiberglass tails, so I get to wave my hand over my bikes tail and it magically turns on. Kinda like my gf...
