Quick tip for improving the code: instead of useing those rather compilcated switches just replace the filename with String(audiofile)+".wav" and you can record an unlimited number of files.

If you want a spy bug, just use your smartphone. Everyone has one and they are smaller.

Impressive presentation - one of the best I have seen, great job!

Great work! It's always nice watching a product of yours.

Another week, another great video!

Thats the kind of video why i subscribed to your channel I ordered my first bpc at jlcbpc just a half week ago trough you.

I had been looking for this for month haha, your videos are really good

The cool spy-bugs on TV send the audio through a radio. This gives me an idea for a "DIY or Buy": a walkie-talkie. There are a few very basic walkie-talkie tutorials based on arduino, but nothing really nice. You could try the analog version too, but a digital one would be more fun: sample the audio with the ADC, then send it over the air somehow (LoRA module maybe, or a cheapo 433mhz ook module pair), then receive and play it back with a DAC from resistors (or use a DAC chip, or a micro that has a DAC built-in like the SAMD21 found in the Adafruit Feather M0).

why not using the onboard led for notification, it would consume less power and you don't a extra led

Unless you PWM it (and given the inherent complexity of recording audio on something so much not designed to do so), I think that would be a higher current draw than is desirable.

@@ninovitaliano7943 I'm honored someone noticed, thanks. It's true though, isn't it? The onboard LED is rather bright and it takes around 10-20 mA, and if you're running off a battery you want to cut down on the current draw as much as you can so this is something you would disable first. The other option is to use PWM to modulate the LED, but AFAIK pin 13 doesn't have hardware PWM, so you have to spend processor cycles on this, and I bet that there's not much free processor time left over from "recording audio on something so very much not designed to do so".

for a "spy bug" I wouldn't use a push button with led. With a normal switch you can determin the state of the bug based on the position of the switch and you can use it as wake up signal to save battery when the device is off.

Your videos are always really nice, thank you very much.

Finally, you made the video i asked for;-)

This was awesome! I always wanted to make something like that but I could'nt

16khz is a very odd sampling rate. So make sure you always have subtraction of 44.1kHz or 48khz. (32khz, 22khz or 11khz) Also it's good to use some input filtering to prevent extra distortion (Shannon theorem).

You can probably keep the power consumption even lower by downclocking the arduino and pushing it into deep-sleep when not recording. In deep sleep, one can get the power consumption in the micro amp region.

Hello Scott, great and very helpful videos you have there! May I ask you where you order your LiPo batteries from as a fellow German? Chinese traders don't ship here as far as I know. Thank you!

some micro FPV cameras i use on tiny drones can record and broadcast medium fidelity analog video and audio at a tenth the size. they only require the camera/Tx bundle and a gumstick battery to operate, meaning its about 27g and 5-6cm^3.

no, and if it's cheaper I don't see the point. I've made my own microcams before CMOS sensors had a processor and body that small, but i have no practical use for a spy bug, just a suggestion. no need to be so pretentious.

Really..... Ur videos are really informative.....!!!!!😘😘😘😘

I've found using standalone AVR chips plus a crystal to be cheaper and smaller than using even Arduino nanos, plus an ftdi USB to serial adapter only for breadboarding. I use a pro mini as an ISP since some vendors who claim their AVR chips already have the Arduino bootloader are less than reliable in their claims.

Please make a videos about galvanic isolation, safety and upgrading video for your peltier module cooler 😀. Nice to see you continue making videos for us 😃😃😃.

Hey GreatScott how about a DIY Sunrise Alarm clock. Or maybe even a DIY or Buy Episode about it?

Thanks for sharing 😀👍

Hey nice video also build this on myself. But one question whats the programm you use to record on your pc with this extrem high frequencies. Thank you

How about a VOX function so it only records when there is sound, and mostly powers down otherwise. Could dramatically improve battery life.

Nice video as always, GreatScott never fails to deliver. The only thing that i disliked was the fact that i cant create SD card projects with good frequency of sampling and theres no explanation on hows that solved in this project. How to write on a SD so fast??

bro u r the best......

Please make a DIY or buy video! That would be great! Great video by the way, but make it send the audio over the air (somehow). =)

nice vid bro

i built this and workss great.im having an issue working out how to debounce the switch because i will click once and it wont turn off it takes a few clicks to turn off but it is still capturing audio files

good idea

Oh ya! This is what we want

Amazing

GreatScott! Have you tried to desolder this small mic, solder 3.5mm jack input (l and r channel connect to make mono) and connect any better mic?

This cool, I like so much.your video, Maybe next time can u try use ESP or ProMini make something like Mini GoPro?

You should try a DIY Digital Usb multimeter like the one you have show in previous videos :).

Nice Video Great Scott!! How is ur thesis going? Can you give tips to beginners in general , as to how one can start writing research papers? It seems very hard because most people don't have in depth knowledge . Any advice would be great :)

Why not replace the arduino with an esp-12f, or esp32, and directly beam the recordings across the network to a local PC for storage?

I'm not sure why, but this has made me want to make a combat robot. 😂

Is there a way to Not use an audrino board in this project? And can we store the audio in a SD card?

Disguise as a functioning USB charger and use that to also charge it, allowing the battery to mainly function as a backup?

Could you do some sort of FM broadcaster that uses either headphone jack in or sd in?

How do you know such a wide range of things? What are your qualifications? Btw love your videos and watch them even during exams like right now.

Awesome

Is there a pre-made amp circuit that uses an 3.5mm audio jack as an input rather than a microphone?

"I created a Spybug, but please dont use it for spying" xD

That’s very good project. I am searching for project like this, but my use case is slightly different instead of storing audio files into the sd card I want to print the data into the console. For example I press a button then it will listen my voice and then when I stop for 2-3 seconds it will print the recorded voice in the console or terminal can you help me on that

This would be good to use on a motion activated circuit. I can see this as a crude DIY Security system. It would be interesting to make it only record when sound is louder than a given threshold.
