Instructable on Cricket Chirp

Is there a Instructable on how to do that cricket chirp with your mouth? I've seen other people do it and I really want to know how it's done.

how can I make a cricket chirping sound w/o electronics?

I'm trying to figure out a way to produce a realistic cricket chirping sound, using something mechanical (i.e., not electronic).  So far, I'm not having much luck.  The only examples I've found of what people are calling "cricket noisemakers" are either big carved wooden cricket-shaped toys with a serrated part that you rub a stick against (which doesn't sound remotely like a cricket) or the WWII metal clicker that was called a cricket, but sounds even less like one. A cork twisting in a tapered wooden hole produces a squeak, but crickets use "stridulation" which, if you slow the sound down, is actually comprised of about 6 individual tones in rapid succession.  That's a complication I'm still trying to wrap my head around. Any suggestions? Point of reference: https://youtu.be/CQFEY9RIRJA

First I'm still a newbie at electronics. I know there are schematics for the "annoying cricket" out there.

Is there a schematic or explanation telling me how to make the device give a double chirp then silent for a seond before another double chirp, turning off in the light and then back on in the dark?

The body...and electricity

So a few years back, my teacher had this toy chick, that had two contacts on the bottom. When you touched both, it chirped. Whn you touched one, and you touched a friend who touched the other, it chirped. So if electricity can run through you like that, why cant the same thing work with a battery and something that takes that battery? (leave the +side in, touching the - side, and then touching the contact for the - side)

Looking to activate a loud buzzer with a board speaker...

I have a home security system (fortress SO2) and the door chime only comes thru the little board speaker.  We have a loud shop and sometimes we are in the back and cannot hear when someone enters.  I would like to activate an external buzzer with the speaker chirps.  I've search the interweb :-) and haven't been able to find something that will for sure work. I'm no electronics guru but I can follow instructions or would pay if someone wanted to build me something that would basically activate a momentary switch every time the the little speaker chirps and I could wire up the buzzers from there.  edit: I can solder if needed

I am looking for a device that will listen for a smoke alarm to go off.

All it needs to do is have an indicator that trips when the alarm goes off.  I replace smoke detectors that give faulse alarms but I am never there to hear them.  There are two sounds they make, one is a chirp (low Battery) and a full alarm very loud.?

IR laser detector alarm

With the new Infrared laser pointers etc. there is no way to tell if light is on or not. I think there is a need for a IR laser light detector that is small enough to fit in your pocket and could be clipped to your shirt. If a IR laser was pointed in your direction the sensor would chirp or make a noise. I've noticed several places selling IR laser pointers. I think they are dangerous and very little use for them, since they are invisible. Anybody want to make one? If you do I want one.

The New Pollution

A green revolution is supposed to lead us to a utopia where the birds chirp and the human stain is smaller on the planet, but sometimes the new looks a little too much like the old.Take this story about biofuel plants dumping glycerin into rivers. Sure, it can be broken down by organisms, but it still causes big problems when dumped into ecosystems, just like the black stuff."They're really considered nontoxic, as you would expect," said Bruce P. Hollebone, a researcher with Environment Canada in Ottawa and one of the world's leading experts on the environmental impact of vegetable oil and glycerin spills."You can eat the stuff, after all," Mr. Hollebone said. "But as with most organic materials, oil and glycerin deplete the oxygen content of water very quickly, and that will suffocate fish and other organisms. And for birds, a vegetable oil spill is just as deadly as a crude oil spill." Link to nytimes articlevia treehugger

How can I make a wake-up light? Answered

You must've seen them before, those alam clocks that simulate the "rise and shine" feel when you need it the most: winter. Now instead of wasting money on one with chirping bird sounds and other stuff I don't need, I want to build one myself. The problem is that this would be my first design of an electronic device, and I don't know where to start. Should I get an arduino for being the clock + alarm clock part? Is there a more elegant way of having a 1Hz alarm clock triggering a light dimmer circuit? Is using an LED bulb a good idea? Where do I start? The fundamentals don't seem that complex, but it's putting it in practice and actually drafting the design and picking the right components that's hard.

Talking Clock

Hi Everybody, I'm new to the forum of inscrutables, but I've been bored at work recently and been thinking of things to brighten the place up. I've come up with an idea, but have very limited technical skills, if somebody could just point me in the right direction so that I could start this project I would be really appreciative and would post up pictures and videos of the final product. Idea: Essentially, I work at a pool where the lifeguards rotate every 15 mins, which they forget to do OFTEN! Me and a few others have decided to make a clock to replace our current one that would, every 15 mins make a noise, or say "rotate" to remind them to rotate on time. It would also be fun if we could have several different voices saying "rotate" of different employees. I'm pretty sure this can be done because I've seen clocks that make bird chirping noises, But I can't figure out how they work. Any help would be awesome, I really want to learn new things, which I think is everybody's reason for being on instructables anyway. Thanks, George

remote controlled light - revisited

Hello, Instructibles gang…. I originally posted a similar question over the weekend, and then got some feedback telling me that there wasn’t enough information to bring in worthwhile responses. My intention wasn’t to be secretive.  Rather, it’s a project that’s still in the planning stage and there aren’t yet many specifics. But I think I can still flesh it out a little bit, and hopefully gather some more specific suggestions. I’m planning a sort of a scavenger hunt thing coming up in October. Most of the stops/stations will be fairly straightforward “orienteering”-type scenarios: “20 paces at 250 degrees,” “north to the hollow stump,” that sort of thing. But I still want to mix it up a little bit. One of the ideas that’s swimming around in my noodle is that, at one stop, folks will be told to “push the button.” It will be dark, so they’ll have to hunt for the “button”… basically a doorbell… and maybe secured to a tree (in such a way as not to harm the tree). When they press the button, a light will be illuminated at a short distance, leading them to their next stop. I know that I could easily do a simple circuit with actual wire, but it would be far nicer to achieve the same result wirelessly… and even though I’m not very electronics-savvy, I imagine it would also reduce the problem of resistance in the circuit. This only needs to operate over a relatively short distance… almost certainly less than 100 feet… probably much less. And while it must be able to operate out of doors (a woodland trail in a rural/suburban park) it only needs to last for a few hours. An LED… or maybe a chirping sound effect… something that would draw seekers from one spot to another. Thanks for any suggestions. And please let me know if more information is needed.

Caring for a toad with a broken and infected arm? Answered

Last weekend I found a toad with his arm trapped in a mousetrap.  I don't know exactly how long he was there, but I discovered him when I heard this shuffling sound from the back of my garage and heard flies buzzing.  Upon investigating, I found poor Toady.  The flies had already laid eggs on his wound.  He was trying to hop away attached to the trap.   His arm is clearly broken.  He didn't have significant blood loss, but when I first opened the trap his tiny bones were visible at the injury site. I put Toady in a small bucket lined with moss and vegetation, along with adding a little bit of water, and covered the bucket with a dishtowel.  I used cotton swabs dipped in saline to clean the wound and applied antibiotic ointment (Neosporin without painkiller).  I also tied a thread slightly above the injury site to act as a tourniquet and prevent further infection, and possibly allow for his limb to naturally come off. Below the injury site is swollen, discolored and infected, growing a fuzzy fungus.  I've been checking on Toady every other day (I wasn't wanting to stress him out too much with frequent visits), cleaning his wound and infection and applying antibiotic ointment.  His arm is clearly dead weight and can't be salvaged.   I've put various bugs, slugs/snails and worms in there with him but I haven't seen him eat.  I put a june bug in there, and the june bug ended up trying to climb onto him but Toady seemed to try and squash the bug with his chest and then hopped over the bug to the other side.  Maybe the beetle is too big for him.  I haven't checked to see if the other goodies I gave him are just hiding under the moss. He doesn't appear to be losing or gaining weight.  He gets stressed whenever I visit, breathing rapidly and either trying to make himself look larger or do the opposite and huddle down, despite how careful and gentle I try and be around him. I'm worried about predators and infection if I were to release him now.  What should I do/not do?  I think I'll try Craigslist here to see if there happens to be an experienced amphibian owner with the proper supplies to care for him.  I doubt any vet here would be able to do anything, and I don't have the money to do so. Is this toad a male?  I thought he was based on his size since he's on the small size, but perhaps it's a youngster?  He doesn't make any noises with me, but I'm not sure if it was him chirping in his bucket or a nearby toad.  I know there's several right in the immediate vicinity.
