nice project. would it be viable to add a charge circuitry for the 3 Ni-MH cells while being connected serially in the battery holder or can these type of cells only be charged per cell ? I've always charged Ni-MH cells individually because otherwise one might be overcharged while another still needs charge so I doubt it could be done.

[@ChunkySteveo]

Wicked little project, the kid will love it!

[@amishjim]

Remember those old Heinz ketchup commercials? Anticipation, annnnnnnticippapaaaation. That's how watching you drill that hole felt 🤣🤣

[@ctonew6155]

Thank you for showing me how easily cut holes in plastic.

[@DavidWatts]

ha ha ha

[@jasonharrington7521]

I searched high and low for this exact tutorial...thank you thank you thank you!

[@leglessinoz]

David, I tend to drill a smaller hole than what I need for plastic (slow drill speed so it doesn't melt) then use a tapered hand reamer to make the hole bigger.

[@UnexpectedMaker]

Watt's at his finest! That was super fun to watch and a clever idea indeed. It's a shame those buttons don't light up more though.

[@kashifmahmood6999]

Would you please provide me Only play back circuit of ISD 1820 IC chip? Thanks in advance.

[@bluedeath996]

Step drills are best for making holes in sheet material, and a bit of water does a lot to stop it melting, as does oil or other coolant but they are often harder to clean up.

[@anglosaxon1622]

Nice little project. I got two of the modules and was looking for tips/ideas. ? Curious, where do you get your components from, after the demise of Maplins? 😥

[@DavidWatts]

UK ebay sellers, Farnell and Aliexpress if I really cannot find something or I want a cheap kit.

[@Ittybittythetwofacedkitty]

Enjoyed! Thank you

[@CassetteMaster]

That is fun!

[@charlesdorval394]

Great video, I'm sure the kid will love it About the plastic drilling, I use some stepper bits for that now, let's just say I had a very similar experience as the clip you showed ;)

[@DavidWatts]

I think I got the same advice the last time 😂 eventually it will sink in.

[@charlesdorval394]

I should have thought that was likely, for me it was as much as a revelation as flux was for soldering hehehe :)

[@DustinWatts]

"I manhandeld some of the holes". A dirty Watts is a joy forever! ;) Seriously nice project! And about the bassyness... a little kid doesn't have any bass in it's voice so doesn't matter.

[@DavidWatts]

Well, the kid it turns out mostly enjoyed the on/off switch deciding that switching it off broke it and he could fix it again, less so the concept of the recording.

[@DustinWatts]

I have to admit... the ON/OFF switch is usually my favourite part of a project too...

[@DigicoolThings]

A cool kids project. They’ll love playing with that! Only issue I see is that 2 year olds don’t turn things off. So you might need to check battery life. Logical behaviour really. Switching something on makes it work. But turning things off does nothing. :-)

[@connorchapman4223]

We haven't seen you for a while.

[@DavidWatts]

I have been undercover

[@AttitudeGames]

Should call it "Crap Box" or "Crap Recorder" lol I remember using one of those chips about 25+ years ago when I did my HNC in Electronics and Communications, you can also do multiple addressable recordings and play each one back separately.

[@Davedarko]

hmm, maybe spray paint it from the inside with something colourful?

[@DavidWatts]

It would look better wouldn't it. Might see what I can get this afternoon.

[@caroman6761]

With this box infront of your Door you'll get some Visit from Goerge Cowly of the CI5 ;-)

[@followthetrawler]

a small hole saw would have been better than the wood bit

[@davidlegault9745]

I obviously have more faith in the destructive powers of a 2 year old than you do. Go for the waterproofing. Regards, Dave

[@Dust599]

hotglue is evil, avoid if you wish to be taken seriously as a maker.

[@DavidWatts]

HOT GLUE ALL THE THINGS

[@BrianLough]

I'm not sure what you are talking about, hot glue is holding the maker community together...

[@MkmeOrg]

Hot glue is life

[@CassetteMaster]

I will never give up my hot glue!
