Creator of Elektrosluch over here. Thank you very much for this :)) I am super glad you like it!

[keatontaylor]

So I wonder if the Elektrosluch could be used to hear the processing on a digital locking safe? Would be an interesting experiment just like when you tried to hack into one by analyzing the power input.

[pcuser]

The sound created with the access led is the cpu writing to the sd card.

[GadgetAddict]

Please do a 20 minute repair video on the laughing track toy.

Remote boot thing - groundplane under the antenna...?
Also looks designed to mount inside, but would need extrenal antenna....

[Mnyut]

29:26 not only stereo please listen to the Elektrosluch via a surround sound audio system, amazing!

[LarsBgildThomsen]

Come on - you have GOT to get that laughing box going :) Never mind fixing plasma TV's, scopes and what have you not - that one is classic!

[pikadroo]

That laughing thing... I had a friend who had one of those from a VHS release of "Throw Momma from the Train" and it was a really effective way of getting a simple cardboard display for the video release to be interactive if you pushed a button. Man... that is amazing, the unit looked just like that!

[mikeselectricstuff]

With that inductor and sound chamber I bet that alarm is loud enough to really piss off your neighbours.

Love Mailbag! And tell Sagan the Internet approves of his mailbag shout!

[AlexTaradov]

That thing probably picks up actual SD card access, not the LED control signal.

[Uncle_Buzz]

Those are some killer quality header pins on the powerbricks. Nothing bodgey there. Cheers, Chris!

[RoyHess]

I totally love that Elektrosluch 3 thing, need to get one too!

[benespection]

Those mini record player things were common in old toys from the era - amazing little hacks. I had a "talking" robot toy from childhood with the same thing built into its chest, pretty much the same sized module as the one sent in.

"I won't show you the voucher code" - Not sure you realise how good your camera is Dave ;)

[mrandmrsliamrussell]

i wonder how that inductor microphone thing would sound next to an electric guitar? +EEVblog can you give it a go?

[rentAscout]

Damn, 13 years old. I can't imagine how many EE careers started because of your blog.

[EpicLPer]

12:17 - Someone pressed the shuffle-button in Dave's head :D

[drusha]

Dave, high pitched voices are strong in your family :D

[doubleROT]

I bought the Arty for working with the SDDDR3RAM. Working nicely, but hope they'll complete the documentation in their wiki.
