Teardown Tuesday
Sorry, this was meant to be just a fun supplementary video. Was going to have another teardown ready as well, but it never made it unfortunately. So this one will have to suffice for this week.

its for the motor when it stalls or is starting up, basically when it requires more current and the supply cant match the draw

[rogertopful]

Was the audio out of sync for anyone else?

[gnagyusa]

Not a tear-down, a bear-down!
Sorry, couldn't resist...

[Chlorate]

Love the outatime plate in the background.

For cleaning up battery corrosion on contacts, I soak the battery holder in a solution of white vinegar and salt. Scrub with an old tooth brush, rinse in a solution of water and baking soda, then a good rinse under plain water and a good dry.

Those 2 Chinese characters are the phonic equivalent of "John" in Chinese. The "J" in this case is pronounced like a "Y" though, perhaps a Hebrew thing, I'm not sure.

I'd love to know how this "ChipCorder" encoding works.Any chance of a quick explanation?

[Sqwaush]

Could of just put a piece of crumpled foil instead of redoing the battery pack.

nice job sneaking in that 3 AA holder in place of the 4 AAA with that edit, not gonna trick me Dave

You can say it is a beardown tues... ;D

For noise suppression a ceramic capacitor would be used, instead of a electrolytic one, right?

[MattJBaugh]

Awwwh, he's grown loads since the last video I saw him in!

[RetroGamerVX]

I like it, looks like mini you wasn't so sure he did lol

Sagan was thinking, "dumb adults, bears don't sing"!

[RandyLott]

Sagan will understand in time... in time.

My family has some animated Christmas Decorations that sing We Wish You A Merry Christmas and they got damaged by rats, I pulled one of them apart and discovered that it had a similar box inside it. You should try and get your son a Teddy Ruxpin, he'd probably love it.

9:58 "I must know how this device works"

[banjax]

I'd say the capacitor would be for noise supression...

[UberAlphaSirus]

The things you have to do for the kids aye! I had to do a teardown and rebuilld of a my 4 year old daughters toy called jo jo from waybaloo, after the washing machine incident...

I'm always up for teardowns, but I'm also really interested in older electronics and want to learn about how well various components cope with the aging process. I know that capacitors can dry out over the years and go pop, but how about other components?
