You can isolate the Raspberry Pi’s power from the power on the Voice HAT Drivers. This will prevent the connected device from draining too much power from the Raspberry Pi. The external power solder jumper is marked JP1 (it is near the Servos 5 connection on the board). Cut the connection to allow two power sources to be used by the Hat.

Hi, I recently bought the AIY kit and excitedly constructed it, however, I was somewhat disappointed to discover the note on page 49 of the instructions -

At this time, the Cloud Speech API is not available to use with the AIY Projects Voice Kit. In the European Union, Google Cloud Platform services can be used for business purposes only, including the Cloud Speech API.
Learn more here: cloud.google.com/free/docs/ frequently-asked-questions.

As I'm in the UK does this mean that I'm somewhat crippled as to what I can do with the device?

Can anyone please advise?

Thanks,

Andrew

"multi-microphone options for Pi"

would like to know, other than Audio Injector (which is not just for microphone)

I know that there were other Posts to this Thread, but sometimes they do not show up. Anybody experience this? AAR This Google AIY is a "portal" to the Google AI Machine in the "Cloud". By phrase-ing your Query differently/alternately, One might get different/Better Answers. AAR2 has any e14 commenters know-of/ever-taken a MOOC on AI/Machine-Learning/Neural-Networks? Any Recommendations? I forsee the possibilty of Google/Amazon "opening" their AI offerings for more specific/directed Queries that use particular AI Algoritms. For $$$ of course.Shades of the 1970's/80's Computer Time-Sharing. It would be nice to be on-top-of/ahead of this "next-big-thing".

Thank you so much for this blog post.

Do you think i can connect some 5v DC motors directly to the Servo Pins?

Or do I need to put a L298N in between?

With kind regards,

Thomas van Latum

Hi all,

I wrote up a tutorial for those who want to experiment with AIY but do not want to spend on the kit or magazine. It is on hackaday.com at How to Build Your Own Google AIY without the Kit | Hackaday

A special thanks to [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05] sir for the kit and support.

Cheers,

To Ray S. Here I (we?) go again! If we ALL state what country we are residing in, the Q's raised would have Direct answers. AAR, not knowing what country you are in, I can Only speak for myself. AAR I am in the USA. My local Barnes & Noble Booksellers (Union Sq. NYC) was sold-out of MagPi Issue 57 (this had the Google AIY Kit). I was able to buy one ($14.99 USD) at the Brickn'Mortar Micro Center Store (Queens County NYC) - 16MAY17

Where can I get the "VOICE HAT" and the "VOICE HAT MICROPHONE" ( I might be able to use the "Adafruit I2S MEMS Microphone")

But I much rather use the OG equiptment....

I was not lucky enough to have gotten one of the KITs...

I am looking at the tear down..... I can NOT locate it ANYWHERE....

Anyone know???

I wonder why do Google need to use an EPROM on the audio output section of the Voice Hat?

Excellent work, that's what i've been looking for! I will try to solder it myself

A couple comments, now that I have been running this thing for a while I've noticed a few things, it works well, but after a couple of days it gets lazy -- it still goes into recognition mode after aclaptrigger, but it fails to decode the voice commands and just says ' not recognized '. After you restart the program it works fine again. This won;t due for controlling my Iron Manwheeled exosuit.

So I am looking into Mycroft as a possible substitute. This platform is OPEN SOURCE so when there are problems like this we can try to actually solve them. I asked them if you have to remain tethered to WiFI like Google after initialization, and that's where the communications channels went dead so this may be an issue here too. This platform can run without any HAT board, although I think they already have it workingwith some parts of the HAT, like the button.

Hey Shabaz,

I work for the Raspberry Pi Foundation, and I'm making a kids educational resource on using the Voice Kit to make an LED blink. I'd really like to use the schematic that you posted here. Did you draw it yourself? If so could I have your permission to use it in the resource. You can contact me at marc(at)raspberrypi.org.

To FV: I was ab[e to buy this Coogle AIY (MagPi(issue7?)) At Micro Center Store (Queens loc.) NYC USA for $14.99 USD. Thx for info. The local B&N (Barnes & Noble Booksellers) sold out on this item.

To Shabaz: WRT this Google AIY Project, Would there be any Benefit to using a Faster ARM processor. I saw on sale at Micro Center (Brick & Mortar, and Web-Store) USA, an ASUS RaspPi-3 Form Factor SBC (Single Board Computer)? I have an Up SBC (RaspPi 3B Form Factor) for another Project - am trying to get WIN10 on this SBC (having an Atom uProcessor).

BTW WRT RaspPi-Zero-Wireless, I got RPi-Z-W to work w/ Raspbian 2017-04-10. The RPi-Z-W's Wifi works fine. BTW2 there is Reverse-Polarity DC Protection on the RPi-Z-W, I saw it on a schematic (Dual Zener Diodes). AND I accidentally crossed my 5Vdc, this RPi-Z-W still works.

Thanks for posting the output drive. I already fried 2 channels on 2 boards trying to guess. How does one reset or speed up resettling of the fuse????

What is preferred way to drive a regular relay on this output, or for that matter, an opto-isolated relay?

thanks all.

also, does the stero mic permit sound localization and/or distance discrimination via timing differences so that external noise can be discriminated by phase/timing and triaged out? how does one access this I wonder??

Note added: fuse may take a while to reset:

via https://en.wikipedia.org/wiki/Resettable_fuse

This cooling usually takes a few seconds, though a tripped device will retain a slightly higher resistance for hours, slowly approaching the initial resistance value. The resetting will often not take place even if the fault alone has been removed with the power still flowing as the operating current may be above the holding current of the PPTC. The device may not return to its original resistance value; it will most likely stabilize at a significantly higher resistance (up to 4 times initial value). It could take hours, days, weeks or even years for the device to return to a resistance value similar to its original value, if at al
