Homemade radar screamer

[Dschubba]

Gidday, sorry to be a killjoy but I found a few problems with that circuit

The Solid State Relay you used is for an AC load, so it has an SCR type output.
Once an SCR starts conduction and input is removed, it will continue to conduct until the load is removed, or with AC until the voltage waveform crosses zero (which happens 50x a second).

The SSR you used seemed to work with a small load, but once I attached a grunty screamer she kept on screaming! Did a search on the net and a few other people had this question.

Also the capacitor was inline with the load, where i think I would put it across the screamer if you wanted a longer tail on the scream. With the big screamer I haven't bothered with the capacitor.

I used these parts from Jaycar:
CAT. NO. LA5255 (Tweetie Pie Screamer 116db)
CAT. NO. SY4092 (Solid State Relay )
I put a small diode IN4004 in series with the mono 3.5mm plug with the white end of the diode attaching to the +ve input and the other wire from the plug to the -ve or the SSR.

Then from the battery to the red wire of the screamer, the black wire of the screamer to +ve load, and from the -Ve load to ground.

Now just to work out where to mount the screamer on the triple. Mind you it so !@#$% loud, probably mount it anywhere.

Any chance of a circuit diagram ? Tis a bit late .. perhaps it will look clearer in the morning!

Just wired this up on wifes triple. Her bike has no protection, mine in shop, and i got stung on way home from work on hers... Blah.

Anyhow, this was simple and seems to work reliably.

Note its important that you get the SSR for a DC load Part SY4092 i tried a few others and they sometimes stayed on.

Good luck

On a similar topic, I have a question-- I've got a passport escort x50 from the states, and in testing it, I can't seem to get any audible volume. (over the sound of my bike, which is decently loud.) I don't know if my head phones are shot, if I've got the volume set the wrong way (the dial on the left). or if I just can't hear it over the sound of my aftermarket exhaust.

I've got a honda firestorm as well as the OP. Same bike, same radar detector. You mentioned that it puts out 5 volts when triggered? So 5 volts out of the head phone jack? Could you run an LED off of that, how many milliamps do you figure it can handle?
Cheers,

Try another pair

....if I've got the volume set the wrong way (the dial on the left).

try it all the way clockwise, then all the way anticlockwise

...or if I just can't hear it over the sound of my aftermarket exhaust.

Turn the bike engine off, leave the key on accessory or whatever makes the detector turn on.

Maybe I'm missing something here, but do you mean that you think the unit has a problem or just that it's not loud enough and you are thinking of a screamer? It should be easily loud enough in your headphones with the bike engine off.

You can not run an LED from the headphone output directly. You need an interface circuit. You could run an LED (with resistor) from the solid state relay circuit that has been shown on this thread, either with or without the piezo screamer. There are better interface circuits, but it will work.

Interesting read thanks for that

Thanks to this thread, I have realized that re-purposing a smoke detector is the ideal solution to something I have been meaning to get round to for a while - a laundry flood detector!

It's easily installed, has a low battery warning, loud enough to be noticed, and CHEAP :-)

nt i use a standard 12 v automotive relay instead of this 4 pin relay? im not sure what the difference is? anyone help?

[rapid van cleef]

hi. well ive finally got the relay today and im stumped. the relay(5v solid state relay from jaycar)

so, as im looking at the printed markings on the front, do they correspond with the terminals that are immediatly oppositte them on the rear? thats how ive wired it. and when the ignition is switched on, the sirens goes off, no switching occurs, its just on!

Or,

Are the terminals actually the oppositte way round ,so the top left terminal which is marked pin 2 neg on the printed side corresponds with the top left pin when i turn it around? so it is in fact oppositte?

does that make sense?

thanks

well finaly got the correct relay and finished the screamer as per Dschubba's diagram above. had a few issues with the relay not being labelled. but it works great. i even wired in an on off switch mounted on the L/H side of the bars to turn it off in town. all home made and works a treat! now to add an LED alrt to it too.........just for the hell of it.

i know this is an ancient post but wanted to thank you for posting the diagram, just made one for my escort 8500ci and it works amazingly well. i actually used a $45 floyd bell twin turbo LED/Screamer combo that is top notch.

if you are still around, can you add the switch after the fuse on the batt side? im using a lighted switch so when i wired the switch to the red wire like you suggested, the light only comes on when the radar goes off.

thanks

I find my ear piece works perfectly well.
