I've been going out with a guy for about a day now. We were best friends and then he started to like me. I think that it's so weird to go from best friends to girlfriend and boyfriend! I want him to understand do I wrote him a note. It mostly said that i would feel more comfortable being friends.

Hai guys.. I'm doing a project to get the heart beat through a mic... So I connected the top end of a stethoscope to a tube and the other on of the tube to mic (seal tight). The mic is an Arduino mic module. Using anlogread function I'm getting an input with lots of numbers and when plugged into to direct audio to my Mac I hear the heart beat. What I want is to see the bpm from the reading that I'm getting from the Arduino not just random numbers. Is there any way from doing this? Thank You in advance...

I've got a Polar heart rate monitor, which includes a chest strap and a watch. The strap sends out an RF pulse for each heartbeat it detects. These pulses then get counted and then displayed by the watch on your wrist. I would like to be able to intercept this RF pulse and do my own thing with it. My initial idea is a treadmill-mounted device that displays the current heart rate and at least some sort of min/max display, indicating when you are in the ideal HR zone. I think I know how to build the device, but the first step of intercepting the pulses has got me stumped. Anybody know the specifications of the strap and how to get the signal? Thanks!

Hey, just wanted to let you all know (so, maybe I put this in the wrong forum) that I am up this early in the morning ( 6:30 am ) because I have to go to the hospital for a complete cardiac / pulmonary workup and battery of tests. Yeah, getting older stinks, especially if you let you physically self atrophy. Anyway, just wanted you all to know, in case you don't see me for a few days or longer (the tests only last about 4 hours or so, but they could potentially bring on cardiac arrest, or trigger a severe asthma attack, depending on the kind of shape I am in ( it is kind of a pregnant pear shape actually ). See you all when I am back from the hospital....Addendum: I have a lowered amount of blood flow to my heart. What this means is that I am a borderline heart attack candidate if it gets any worse. Cholesterol was a little high, triglycerides way high. I will find out details on Friday I suppose when we discuss options...Addendum 2: The pulmonary tests ( 05/21/2008 ) were horrible, but there doesn't seem to be anything overly wrong that is obvious to the tech, with my lungs.....will have to wait for the doc's report thoughAddendum 3: Well, I am afraid things have progressed to the next step... I have to have a heart cauterization to see what may be blocking the lower artery, and how bad the blockage is. If not too bad, they will simply do a quick angioplasty and open it up, but if bad, I will then be scheduled for a bypass. *sigh* as we age the fun just never ends, eh ? Addendum 4: It will not be THIS coming week, but most likely next week, they will do the double bypass. Because of the location of the blockage at a major branch which would end up cutting off flow to the other artery, they have decided I best have the bypass done. PS: there was hardly ANY pain in the cath procedure.....I am going to give the person that told me that a hard time next time I see them :-) But I have experienced broken bones already, so I know the next step is not going go be a picnic. Addendum 5:I may be able to get the bypass done as early as Monday the 9th Yay ! Addendum 6:I am now into my second week of recovery, and things are progressing so well, my wife is afraid I will want to go back to work early and she will be alone again.

Hey all! Me again :D. So I was messing around with my electronics and decided to make a pulse sensor, but I ran into a couple of problems along the way! My project is based off of this, http://makezine.com/projects/ir-pulse-sensor/, but I didn't have a LM324, so I was trying a workaround. So grabbing my infrared light detector, and new multimeter, hooked my IR sensor up between 5V and and A0 and a 10k resistor from A0 to GND, just like with a light sensor, but obviously, it wasn't sensitive enough, so I kicked it up notch. Since I didn't have the specific amplifier that MAKE used I decided to use what I had, which was a LM358. After visiting the datasheet and finding a schematic, I came up with this circuit (image below). Now it's not sensitive enough yet to measure pulses. The circuit from MAKE makes use of the the 2 of 4 internal op amps in the LM324, and I thought I could make the same circuit on my LM358, since it had two op amps inside of it. So basically, replacing the LM324 int the circuit with a LM358. The image below is a circuit I made up using just one of the LM358's op amps. Tonight I will try to use both just like in the MAKE circuit. If you guys could just give me a few pointers and set me on the right track that would be great, or if I even need two amplifiers! Why can't I just make the first one more powerful? And the capacitor between the - and the output varies. I'm still trying out different caps. The 0.1uf is too much, so I'm experimenting. Thanks!

I have never done any wire crafting but i want to make my friend a gift of maybe a Celtic heart knot made of wire. I figure wire would be the easiest to work with. if anyone has any ideas of where i should start....?
Asked by timenight113 8 years ago
Ohkay, so I have an idea for a cute gift. The idea is to make two heart pendants that get brighter depending on how close they are to each-other. The problem is, I have no idea how to go about the dimming aspect. I've never even held a soldering gun, let alone used one. But I'd be willing to pick it up for this if I had a good tutorial/instructable to go off of. Even a general idea of what to look into would be great. I've seen similar things like the WiFi detector t-shirt at ThinkGeek, but again I'm a n00b when it comes to this stuff, so I don't know how useful that is when applied to something like this. Any help would be much appreciated, this is most definitely a burning question that's been bothering me.

I got a premade heartbeat sensor which uses an IR led and an IR receiver to sense heartbeat. It gives out an analog signal, which i have connected to my Arduino's A0 pin, and uploaded the analogRead sketch to it(sends values to serial port too). Then to visualize the heartbeat i used a processing graph program that took the values from the serial port. When i place my finger on the sensor, i get this graph shown below: Yes its very clear, but can anyone help me with the code? it just needs to measure the beats per minute, and store it in a variable. ** The spike in the grph showing the pulse varies in height sometimes. So the code should calbrate and all. Also there is a 1-2 second delay before the clean pulse comes...

I love to graph things. Everything from outside temperature to server room temperature to the number of users on the network to my weight.I just read an article in Make magazine about DIY ECGs, and it got me thinking.. i want to graph more things about my body :)Would a microphone embedded in the bed be able to pick up the heart beats and calculate the BPM? This way I could graph development in resting heart rate over time. The microphone would pick up lots of noise from the person moving around etc.. but that doesn't mather. It only needs to get a few clean heart beats in order to calculate the bpm, right?What hardware and software would be suitable to create something like this?Any ideas?Yeah, of course there are other more traditional ways of measuring heart beat.. but I'm to lazy to do that.. I'd rather spend some time making a fully automagickal system.

I was thinking that the headphone jack could be used as an input for a 3-lead ECG (EKG) and used to cheaply monitor arrhythmias in remote areas (or in the field) and record and/or send these to health professionals. It needs to be able to detect milivolt impulses from a pos/neg/ground input.

After seeing hay_jumper's post office art and revenge of the post office art instructables, I decided to give it a whack. Just so proper respect is given where due please note that l read hay's instructables once and remembered the ideas several months later that's how awesome this idea is.I wanted to make a creative valentine's card for a special friend who happens to be very very talented at all that creative stuff that I tend to suck at. I figured the best way to impress her was to FAKE IT!I basically copied what hay did except l most importantly used a heart-shaped fence to make a specific shape and a (much) smaller stylus than his second project. The pictures should explain most of this madness. The stylus was made with two square layers of foam i cut and PLENTY of glue (in between layers as well as in/around pencil holes.Aftermath: I decided to send it anonymously and she called the middle man (who I used to add further anonymity as well as shipping time) and told her how awesome it was and asked for my phone number. THIS SHIT WORKS, GENTLEMEN. TAKE NOTE!

Got a frozen beef heart at the Food Bank (times are kinda tough here in Gorframville (just like everwhere else..)), and I'm not sure how best to cook it. A slow roast to keep it tender? Sear & grill to seal the juices? Broil with salt, pepper, and a dash of balsamic vinegar; or stew up with half the contents of the pantry? I've never cooked (and only rarely eaten) beef heart before, so I'm kind of nervous about it. Any help or suggestions?

Hello, I got this watch Polar FS1C as a gift, unfortunately without sensor which is necessary to collect data from heart rate. I would like to ask you, clever guys, if is it possible to (home)made cheap sensor suitable for Polar FS1C? I could not buy this sensor in Slovakia in reasonable price so I am trying last chance here, to built it on my own. Thank you for reply. Mx.

The circuit's purpose is to be able to listen to heart sounds and output it in a PC and the heart sound frequencies usually fall under 20 to 100hz. The problem is when i plug it in my laptop, i start to hear the hums. But when my laptop is just powered by the battery it completely removes it. Is there another way to eliminate the hum without having to run my laptop on my battery?

Hello, I am designing and making a prop for a music concert and would like some advice on the best way to go about it. The prop needs to be a glowing/lit heart that starts off on stage as a series of glowing rods. The artist then constructs the shape onstage and it becomes this glowing heart. I am thinking of using some sort of plastic tubing and LED lights, but Im not sure how to construct them so that they can: - start of as individual rods then fitted together in a specific shape - they need to turn on and off an be able to have the batteries replaced. - must be bright red glow - lightweight and low heat. If anyone has some good ideas or advice on how to construct it I would be really grateful. Thanks guys!

This is for my final project for one of my university papers and what I want to do is to make a object that can amplify or create the sound of the heart and can either worn on the hand or the neck like a necklace, as a form of communication and/or self expression. Visual aesthetics are important for this one so ideally, if its possible Id like to make this wearable object portable and super simple since I'm an amateur when it comes to anything electrical like this! I did see another question on this site which was practically the same as mine, amplifying the sound of the heart beat for a project and one of the comments mentioned using piezoelectric elements to pick up the movement of the veins and therefore create a sound through an amp and a speaker. This would be perfect for my project even though its not the exact sound of the heart but its doable, except connecting it to an amp etc isn't exactly small or compact enough for it to be wearable. (Here's the web address to the other question I mentioned above: https://www.instructables.com/answers/How-do-I-connect-a-stethoscope-to-a-speaker-How-/) So...is there any other way to use piezoelectric elements to pick up the movement of the veins and output it somehow preferably through sound, but representing it visually through LED lights could also be an option, but again, how do you make this inexpensive, wearable and simple to make?? Any suggestions anyone?? Thanks :)
