£5 Friday: ISD1820 Voice Recorder

£5 Friday, a silly series where I take a look at interesting things you can pick up for £5 or less from the interwebs.
Don't judge, this is just a bit of fun, I felt like I needed a change so I dragged this old thing out. I am sure you will have a hundred different uses form a module like this.

This is hilarious - what a great video of learning how something works and showing all the normal mistakes we all do at times ( instead of editing them out) - so cool! Thanks for posting this

[@StephenMcLeod]

I am going to have to try one of these. I've had the board sitting in my drawer for about a year. Thanks for sharing! Appreciated that you kept in the various screw ups/minor hiccups!

[@samuelgonzalez7783]

thank for adding more on my favorite module list. I would really like to get one of these.

[@stevemaherart]

Hey David, this was super useful for me, thanks!

[@mankee2211]

I find it easier to solder cables on pinheaders on the backside, where there already is solderpaste.

[@jeffjgale]

David, Great mate, I'm using these on my n scale train layout, one for each section eg; waterfall, sawmill, station etc. solder on a switch to the playl switch.

[@nrdesign1991]

i had a similar module as a kid - we used to play around with it, screaming and making weird noises. Good times.

[@urameshix15]

Hi, is it possible to send a short sound effect to ISD1820 instead of recording with the microphone? Regards

[@EpicProvider]

FT mode, when short FT jumper, that means all sounds to MIC will direct playback to Speaker.

[@erisamehmeti2241]

Hi! We're doing a project with PIC877a and isd1820 ,its a RF transmitter receiver circuit. i wanted to ask if you could make a video on how to program the isd module with pic. Thanks!

[@zsombor_99]

Actually if you remove the microphone and connect an audio input instead it works just fine, it can record what you playing into it.

[@loekhove1084]

Could you make a list of items that you need for this?

[@ishahakeem]

Hi, quick question. How do you change the batteries? I have this music box (not a traditional one, one with this module in it) and it won't play well, I think it's because of the battery but they are in this metal casing that I can't get into...

[@DavidWatts]

Hmmm, I haven't seen a setup like that before. It sounds like you will just need to replace the batteries, cutting it out potentially.

[@Bruceleeeroy]

Cool! If you press the PLAYE button again before the recorded audio has run its length, will it immediately start over? For example, could you do a rapid fire laser sound if you press the PLAYE button rapidly?

[@DavidWatts]

I would have to hook it up again to check but I believe so.

[@asdasdgification]

Is there any way i can record audio to pc at wav form with an arduino and an sound sensor. I don't want to save it on an sd i want real time record

[@wrongsideof40]

I've just found one of these units languishing in a draw. I have a use for it but there seems to be quite a lot of (not so) background noise on the recorder's playback. Is this normal, do you know, and can it be tamed? Enjoyed your video - thanks!

[@hasancuhadar4866]

Is it possible to raise the sound?

[@iceberg789]

cool ! feed the transmitter 1kHz music & get an oscilloscope to probe into it. and you will understand everything ! :)

[@pierreminvielle]

Magical voice mirror. Evolution whith pieces of stones. And some dust.

[@saifmm7423]

hi can i use SD and arduino with the isd1820 for long time recording?and how? thanks

[@DavidWatts]

Sorry I don't think that is possible.

[@nor4277]

Can I ask what pins you used to hook your power,my module looks very simaler,my speaker has a dedicated jack,and doesn't have the side switchs,but the rest is the same ,I notice you used 4.5 volts good to no,I just need to no what pins you used,I found the ground pin,did you hook up the plus to FCC.anyone please

[@johncoops6897]

Simply connect to the VCC and GRD pins that are clearly marked on the board that you own. Everything you need to know will be listed on the webpage from where you purchased it.

[@johnhardig9754]

I am having trouble using the FT feature (feed through). Does anyone know how to wire up this function? maybe use a switch? Please help me KZbin!

[@douro20]

I wish I could remember who makes those chips now as Integrated Speech Devices is no longer in business.

[@olegmalyarenko2624]

Which type the battery and the wires it needs?

[@gamerhalim4717]

Can recoding about 4 minutes?

[@SuperLittleTyke]

The battery box supplies 6 volts. Is that not too high for the board? With my ISD1820 I took 5V regulated power off a Basic Stamp board.

[@DavidWatts]

Those were NiMh cells, so would likely have been kicking out around 5-5.5v. The ISD1820 can run from up to 7v according to the datasheet but that is a maximum value, normal operation is stated as 2.7-4.5v.

[@SuperLittleTyke]

@@DavidWatts Thanks. What is the theory behind the Pringles tube that causes the volume to increase to such an extent? (Using the supplied speaker.) Could I use a small wooden box from e.g. thin plywood and cut a hole in it for the supplied speaker?

[@DavidWatts]

I think it just increases the area that reverberates giving a louder base sound.

[@lordpitnolen2196]

It will soon be (or is already) a legal requirement in Europe to have some sound emanating from electric vehicles at very slow speeds. You mention speech recording but, presumably, a low frequency recording of a motor sound could be made. Also, would it be possible to tap into the PLAY switch to have a remote button on the vehicle dashboard? Thanks.

[@DavidWatts]

Sure that sounds possible. The car running off 12v would be your biggest stumbling block. A playing card in the spokes worked well on my bike, we need a 2020 car version!

[@lordpitnolen2196]

@@DavidWatts Thank you..We couldn't afford playing cards, just scraps of cardboard :-) If used incorrectly it would unscrew the valve !

[@DavidWatts]

@@lordpitnolen2196 same, I said playing cards for the visual clue. Really it was bits of old cereal boxes 😂

[@rdarchitect]

sir what happen if PLAYL pressed all the time, is that looped sound?

[@LeapFrog_Radio]

This depends on jumper configuration and button pressed, please refer to the datasheet.

[@juniorengineersk4859]

Where can i get that mat

[@DavidWatts]

Amazon is where I got mine - amzn.to/2BVnNYL

[@giorgioa.tsoukalos3653]

Alien's technolgy is much better

[@rksoftwareltd]

I assume they were 4 x 1.5V batteries you used to give 6V, and it was ok? (Unit is rated 3-5V.)

[@DavidWatts]

I believe they were rechargeable batteries so 4.8-5.2v is a reasonable figure for them.

[@karlng2691]

Is this going to be a weekly series?

[@DavidWatts]

It will be a reoccurring series but I am not sure if I have the spare time to make it weekly.

[@karlng2691]

+David Watts Thank you so much David!

[@martijnvdbrakel7578]

ouchhhh, why solder when U can use cables

[@nazmulhassan7008]

Only for 10 sec😀😀😀

[@amitsheryaar8470]

I want to recorde my voice for max 20 seconds and fit it in a box so whenever my girlfriend taps on box it plays my voice so i want a recorder with sensor. Is it possible and do you do shipping as well. Can you ship it to me. Reply asap 😅

[@giorgoszampetas7875]

It doesn't worth.. the sound is too low and short time.. if u use the resistor then the quality will be too bad..

[@DesertVox]

So, you couldn't get a proper female header to solder those wire to, right? Sloppy electronics.
