Dog Collar Hack

I am wondering where to go to get some help shrinking the size of our dog training collar. We only use the beeper but it has vibration and shock elements. The collar is too big for our Chihuahua and I am trying to figure out how to remove the unwanted items and print a new, smaller enclosure. We would still need the transmitter, beeper and battery.Thanks, Steve

Glow in the Dark collars for Kitties

This is my first actual post though I've loved the site for a long time now. Anyhow I have two new cats, beautiful friendly, I love them to bits. The only trouble is they are very dark furred and there's been a couple of times they've hidden in plain sight. Me and my fiance are both worried about stepping on them I thought some glowing type collar would be cool. I've been searching the web for an answer and I can't really find anything so I decided to make one of my own. I have limited experience with electronics, I saw the post with an ewire I think it was called collar for dogs. I should be able to figure that out however the cat collar would be much smaller and I don't think it would comfortably sport the battery unit. I ditched the idea of glow in the dark paint (flaking and the cats probably wouldn't appreciate the fumes). I considered some glow-in-thedark hot glue.. but I don't know how to do that without making a collar look lik ea stiff, plasticy, mess. Maybe weaving some of the glow in the dark plastic laces into a collar kinda like the paracord bracelets? Anyone have any other ideas? Anyone heard of some glowing material or even glowing material dye? Thanks :)

How to make a lighted dog collar? Answered

Need a shock type collar for a fixed male cat to stop him from attacking a fixed female cat when he gets too close. Answered

Our 8 year old fixed male cat has decided he hates a fixed female in the house. He only attacks her, we thought fixing her would help, but it did not...he stalks her, and attacks her and bites her around the neck. We thought if we could put a low frequency shock type halter on him so when he gets within a few feet of her it would give him a small shock so he would avoid her. She of course would also have to have a collar on to "see" him coming. We have tried many different things, at this point she is safe in a separate room with a screen door, but that isn't fair to her or the other cats. Thank you and no I do NOT like the idea of shocking him, but I also do no like the fact she can be laying sleeping in a window, doing nothing wrong and he just jumps her. BTW..he is a very large Maine Coon/Siamese mix..about 18 lbs and she is a domestic short hair about 8 it is never fair.

Shock Collar activated by mobile phone call/text?

Hi,  I want to convert an electric shock collar to be activated by a call or text sent from my mobile phone. It has to operate long distance, so I assume some sort of stripped-down mobile device will be needed that can receive a mobile signal.  I have no idea how ot go about this, anybody have a solution for me? Does a device like this already exist, here or on the market?  I tried shopping about but could find no commercial device of this nature, only 'long range' RF shock collars with a maximum range of 1000 metres.

Found old dog collar, can i make it into a sort of taser? Answered

I found an old dog shock collar on my street with a broken collar(not reciever), can i make a remote to make it shock, or turn it into a taser? Basically i want something that i can have fun with, to shock my friends, or my other idea (since i have a mildly aggressive pit bull, would be to make a remote, so when he is outdoors and goes after strangers i can send the small shock it outputs to help train him to not act that way. Please help me figure this out, as i am a geek but know little about electronics when it comes to building them. Thanks. oh also the collar is a " Petsafe PIF-275" collar if this helps at all in figuring out how to do this.

Finding the center of an elipse (I guess) with random points on the circumference? Answered

First thing to note is that this is NOT an assignment for school, it is a real life issue. I'm trying to make a collar for a little laser diode module which has proved to not be centered (as expected, it was only about £5). After sticking it in a lathe pointing at a wall (the wall isn't parallel with the lathe thus making it an elipse problem) and spinning it by hand, I get a wobbly circle/elipse shape which i then marked out on a sheet of paper to find a center point from which I can find how many degrees off it is which will allow me to make a proper laser re-alignment collar.

Using TEC chips and heatsinks for personal cooling - heating collars or pads

I've been toying with using TEC chips (facinating devices that are cheap - applying voltage make one side hot - the other cold, Inversely, appling any existing temprature differential to the sinks PRODUCES POWER). They are used most commonly by consumers in auto beverage coolers and heaters. It  started when a car ran me down on my bike, and I was wearing a neck brace for months. I thought about how misserable I'd be if it were summertime. I also thought of those poor people that always wore them... Anyway, there's a thousand different easy ways to do this - I took fluid-filled plastic sections of a beverage cooler and attached them to a belt, which hangs around my neck. applied the heat  sink of the TEC and there you go - just wrap it in something. Now if I were on a motorcycle in summer and stopped in traffic, the cool collar would be a lifesaver, as well as a myriad of other apps. I cannot figure out the best (inexpensive) way to control this. It's easy enough to turn on and off - you can hardly forget it! But if I allow the chip to get too much wattage it will get too hot and self-destruct. Also, if I limit the wattage correctly, it would just need adjusting, and could be left on most of the time. The idea here is there are many ways to do this but they are too expensive... I want everyone to be able to afford it. If you use a Pot or resistor, the excess goes to heat and ruins battery life, and other controllers of DC current are expensive. Any help? I am almost 60 and have earned the nickname Misc. Expert among my family and friends, and I must say I'm very impressed with what y'all do here in this newsletter - Congrats!

Remote controlled Pager/vibrating device-compact and light

I am new to Instructables and was hoping for some help. I have been reading through many posts and projects to find what I need, but still need help. I am trying to build a vibrating remote controlled collar to signal to my deaf dog. I would like something very compact that has a small vibrating motor in it that also works at a small distance, not more than 50 yards or so. I only need one setting, two would be great if possible. I just want a small transmitter, (size of a garage door opener) with a single or two buttons to produce a small vibration, and maybe a more intense vibration, to get the dogs attention when he is not looking at me. From there, he is trained to visual hand signals. Any help on how to build this, and build it as LEAST bulky as possible? I have seen a few instructables I am trying to piece together, but I am not an electronics person, have done a few projects like building an egg incubator...So far I know I need a transmitter and a receiver, a power source, which I was hoping could be smaller than a 9volt battery, and a small vibrating motor, possibly the minidisc or bullet type that runs off 3V? Not sure if that would even be strong enough, but my dog is pretty sensitive. I am not opposed to spending a little money, as the dog collars on the market are either cheap garbage for around $20 or good quality but have way more unnecessary features than I need and cost a whopping $200. Thank you very much!

Micro Invisible fence transmitter

I am looking to have a Micro transmitter for an invisible fence made. This will need to trigger the invisible fence shock collar when it gets within 2 feet. I have a dog with a shock collar that attacks a smaller, older dog in the house. I want a transmitter that will fit on the collar of the smaller dog, run off of batteries with a LED to show it is powered on. I have an extra receiver to test with, and i can send photos of the transmitter and what information i have. Willing to pay COD for delivery.

Dog bark sensor

Hello!  I'm looking to experiment with a DIY dog bark control/training system, but I'm not sure where to start on the bark sensing front.  I know that commercial bark control collars (don't worry -- I'm not building a shock collar) use a combination of mics and vibration sensors together to reduce false positives and prevent the system from triggering if it is another dog doing the barking.  Any ideas how I could build something that performs a similar function?
