RFID ignition plans

Going completely keyless!

This is my plan. The only downside is the killswitch will turn off the bike completely. No big deal really, happy with that rather than adding another switch onto the bars

Planned it using brake light switch so RFID doesnt drain battery. Also this circuit will turn it off the reader after its done its job and so it doesnt rely on electronics to keep power on when actually riding

Think this will be alright, bout the simplest way to acheive what I want I think

Ahh typical simulation does not meet reality.

Reality = relay buzz and not the right result. I think I need to add a cap in somewhere but not worked out where yet
 
Sonrier (moderator of this section) on the board has RFID ignition switches. Sparck Moto (ad on left side of screen).
 
I dont doubt it and I am sure they are excellent (certainly compared to mine). However I like the DIY approach to electrical stuff, I know I'm weird but I like electric stuff :)
 
Matt's pretty good about making suggestions too, so perhaps he'll chime in here. We all appreciate the DIY spirit, to be sure!
 
My question's somewhat related if sonreir chimes in. I see you can get a harness with RFID added, but is there a kit to add RFID to an existing harness? I.E. stock one isnt bad.
 
Man, using the brake switch is a great idea!

I implemented my own RFID using a toggle switch under the seat. Flip it on, only thing it powers up is the RFID. Once the RFID key is swiped, will power up the main relay whos signal lead is grounded through that toggle switch. Stays powered up regardless of RFID activity until the toggle switch is flipped off again. Also put in a hidden keyed switch in case the $10 RFID unit ever fails.

Instead of using the kill switch as the main switch, you could hide a momentary toggle switch to kill the power.
 
See I always figured if someone wants my bike, chances are it will be pushed away. So mine just has a big old toggle switch on the bucket to turn the whole thing on.

But it's an SR500, so unless you know the secret handshake needed to kickstart the bike, you're not riding it away that's for sure :p

We just switched setups to a new unit that takes up less space and it can be retrofitted to an existing setup.

The ignition switch, instead of turning on the bike, turns on the RFID unit. The RFID unit then turns on power to the rest of the bike. Turn off the ignition switch and the whole bike is turned off as well as the RFID unit.

If you're wanting to go keyless, the other option is to either co-opt the kill switch (like cheese monkey is doing) or to install a toggle switch instead of the keyed ignition.

Dammit, I was hoping I could find a unit that was smaller. I had to zip tie the big black box up under the tank. Any chance you want to share what unit you are using? :)
 
Yup. This one:
http://www.amazon.com/dp/B016D6GPI0

Needs to be wired into the bike and also needs an automotive relay, though.
 
Ah ok, nice, I was looking at that one too. Glad to see it works well enough for you to be using it.
 
I've got one of those units on order too! I'm hoping I can simplify my design when it turns up, depends how it works.

Getting my head around the relay buzz problem. Basically I think the NC contacts are breaking too quickly so I need a capacitor in there to hold the relay briefly. Well it will hold all the relays but that's fine

I think thieves will find this harder to steal than bikes with an easily hotwireable ignition barell on show.
 
Using the brake switch is an ok idea, but means I have to use a NC relay so that the RFID doesnt power up every time the brake is pulled.

So, the sequence would be, pull brake lever. Voltage goes across NC contact and powers up RFID. Swipe tag, RFID then powers up all the relays. They all latch, due to the loop from the first NO contact. The NC contact is now broken so RFID is switched off and brake lever will no longer power it up. Systems trundles along until killswitch is hit and all relays are powered down and system reset.
 
On a vintage bike, these aren't a "true" security feature.

Anyone who is familiar with the electrics can get the bike running with about two or three minutes worth of work. Maybe faster depending on how much of the system you want operable.
 
Yep, under 2 minutes tops on ANY vintage carbed bike. Regardless of your whizbang gizmos.

And again, no self respecting bike thief is even going to TRY to start your bike. Theyre just gonna walk off with it and you're never gonna get it back. Keep em inside!

A pvc lined cable and a lock, locked to a permanet fixture is your best protection against theft. Try to remember that when thieves go out to take something they want it to be quick and easy. Locks are the only way to slow them down or make them look for an easier target.

Cool stuff nonetheless.
 
I guess I've known a few thieves without any self-respect. :p

Around here it's fairly common for the thieves to get the bike started and ride away on it.

A good lock on the rear wheel is definitely a security feature that should be considered.
