Motion Triggered Horns

I'm starting this one over, I made a mess of the last topic. Essentially what I'm starting with is a driveway wireless alert system (  and a car horn. The car horn is wired to a push button switch. ( What I'm trying to do is replace the [S] (switch) with this wireless trigger. The alarm speaker outputs at a very low voltage, ~0.08v: The alarm LED's output 1.75v (measured from + on the one LED and - on the other, there are three total, in series) What would be the best place to tap in to get voltage from to trigger the relay? I think from the previous post I'll need a transistor switch of some sort? This is the part I need help with. Usage: Tractor pulling hayrack riders over a bridge, I'll place the sensors ahead of the horns so by the time the tractor is at the sensor the hayrack is right at the horns. Hope I posted in the right spot. Thanks

How to make a mp3 car horn?

I have only seen one consumer product on the market and it retails about $200. I'm not up for spending that much for what seems like such a simple goal. Is there some kind of  MP3 chipset/micro-controller with a USB input where you can load a .mp3 onto a flash drive (or onboard memory) and then wire it up to a speaker/horn? This all seems really simple in writing but is this something one could actually do?

What to use for making a laser- or otherwise fascinating lightshow come out of an old (big) gramophone horn?

Hi there, I have an old gramophone horn, quite big, which I would like to use as a prop in a show. My initial idea was to have one of those laser-tunnel-effects come out of it (and I would still be interested in doing that) but so far anyone I spoke to said it was pretty much impossible, as it would have to be a wireless prop (so it can be moved around freely onstage) The other option would be to have a laserbeam coming out of both ends, but here the maker of the particular double head laser seemed dodgy and my guess would be that if you buy a laser you want to buy quality in order to not endanger someone. At the moment I am at a loss, so if anyone has an idea what to look for or what to research into I would be very grateful. The criteria for the... light would be: -wireless (battery powered) -somehow interesting effect (a laser pointer would not be enough, unless there is a way of turning it into something more exciting) -small enough to fit snugly into the inside of a gramophone horn (max. 10cm high and 10cm deep, or adaptable to that size) It also wouldn't necessarily have to be a laser, I am interested in any (light)effect that would be visible on a stage. Thank you very, very much for taking the time to read this and if you have any thoughts - I would love to hear them :)

Fishing the traditional way

A while ago I had a very bad day of fishing in terms of catching something for my frying pan or freezer.Same story for the old bloke sitting a few meters away from me.So we decided to pass some time with useless chats about our previous record fish we caught.While the old bloke changed bait I noticed that he did not have a hook at the end of the line.....What is that contraption and how do you catch fish with it?Old bloke laughed and said he goes hunting a lot too and always keeps the antlers from deer and such.Instead of a hook he used a round and pointy bar with a little notch slightly off the middle.Couldn't figure out how this possibly could hook a fish, so got a bigger laugh for it this time :("Make a loose fist, put it in and then pull on the line." he said and I was dumb enough to assume it would not work :(Figure it out by getting two bleeding pricks...Fish swallows the "stick" inside the bait and one there is some pull one pointy end will always get stuck.The other moves until there is no room to move anymore and the fish is spiked up for good.Only downside is that one you get a fish too big it might not grab - bad luck then LOLThis approach instead of steel hooks reminded me of the bamboo fishing poles my grandfather used to make.Be it for eel, trout, carp or even from the boat for pollock and sardine - he loved his bamboo.Even made me my fisrt fly fishing rod from a piece of bamboo :)The old guy however had more than hand made rods or horn needles as hooks.When his hands were still as good as his eyes he even made flies from these horn sticks!He explained the process to me but I never had the patience for normal flies and doing this with horn sticks and estimating how big the biggest fish might be while making sure it is neither too heavy nor fails to float...What I really liked about this otherwise wasted fishing day was the stories I got from the old man."You don't need fancy or oversensitive gear to fish, a safety pin and some packing coad do just fine if you are hungry!"Best story was how he caught a 2m gummy shark with a hand line meant to catch some sardines for bait.I could really his 3 hour struggle to get the thing on board LOLWhat are your most successfull old school or just plain weird catches with something a real sports fisherman would not even touch to cast?

Matching speakers to amplifier

Wiring motion sensing light to include a 120V AC siren?

Here's the goal: to have a wired, outdoor, motion sensing flood light that includes a 120V AC siren that will also sound whenever the light is triggered.  The proposed setup would start with some sort of switch or hidden switched outlet (possibly WeMo so only I can control it and I can also tie in some IFTTT recipes) that the whole system would run through.  Power would then run to an off-the-shelf motion sensing flood light not unlike this one.  From there, one of the light fixtures would be rewired to run power to a 110V AC horn/siren not unlike this industrial unit.  Is there any glaring reason that this would not work, and what considerations should be made vis-à-vis the fixtures wattage rating and the rating of the siren?  The final product should be something that when switched off is just, and when switched on would trigger a light and a very audible siren.  Finally, any ideas on where to look for a siren/horn like the one described?  The industrial unit in the link might be a bit too big. fdsafdsa   fdsaf(not un From
