#

i do indeed yes

timber geode Dec 18, 2023, 7:31 AM

#

i am playing around with it myself.

#

what i could not find out yet are the specs of the audio out - if i can drive the google home mini speaker with it or if it will burn the chips.

#

if you have any insight in that, i would appreciate it

peak saffron Dec 18, 2023, 7:33 AM

#

thats exactly what i was looking at , at the moment... yes the details for it are a bit 'sketchy' i was just about to see if I could hunt down a schematic

#

i drive the google minis off a max 98357 ok... so hopefully it will be of a similar spec. if i cant get the schematic i will get it under the microscope and see if i can identify any of the ic's

#

that's definitely a level of detail that's above my paygrade. 😁

i tried it out shortly, and it was working fine and had definitely a better sound than the noname speakers you see in the picture

#

ah - and i am working on a 3d printed case for respeaker + rpi0 + google home mini speakers
if you are interested, i will share as soon as i finished it (which could take some time)

#

the google spekers are pretty decent to be fair.

timber geode Dec 18, 2023, 7:40 AM

#

agree. and as i had some old laying unused around i gave them a try

peak saffron Dec 18, 2023, 7:41 AM

#

yes ive salvage mine and some out of an obsolete ipod dock that were going to end up in e-waste and they are of similar quality

#

too bad that those devices are unhackable ..

peak saffron Dec 18, 2023, 7:43 AM

#

i wont use it once it's deployed with a speaker as I output to speakers sepratley. just so i can position mics optimally for max range . but want the output in a different area... so when i eventually start playing with a setup for myself it will be seperates. but for testing i'd certainly like to see what this thing is capable of .

timber geode Dec 18, 2023, 7:46 AM

#

how do you plan to manage that on the software side ?

peak saffron Dec 18, 2023, 7:56 AM

#

i've not figured that bit out with the pi yet, but i'm also using ESPHome mics and media players, which I can do within the device configs. but in general things like 'i've turned it off' responses i dont wnt , as if a lights on or off .. i can see it is lol

timber geode Dec 18, 2023, 8:01 AM

#

yeah, ok, that's propably not the best example.
but i regularly ask for example how full the battery of the car is. Or the weather forecast. And it is a good response to play a small "ding" bell sound or similar to signal either that it's now listening because it understood the wakeword or that it now is finished listening and is now executing the command.

#

or that it now starts charging the car. thats something where i definitely want a response.

#

i am experimenting a LOT currently with the software, mainly docker driven, if i manage to find a working solution, i will let you know

#

documenting everything anyway ...

peak saffron Dec 18, 2023, 8:04 AM

#

to be honest i have purely been concentrating on the hardware side and the 'diy' aproach so I've not even started to look into the intent side of things. I have have been testing different esp boards and configs to try and get something that both listens well and outputs well. and have not got that perfect balance yet. once i have i will then work towards planning how i will do the next stage

timber geode Dec 18, 2023, 8:05 AM

#

yeah, you have to start somewhere, and thats usually the side where you feel more comfortable. So for me it's the software side. 😉

peak saffron Dec 18, 2023, 8:06 AM

#

absolutley... i am not a software man 🙂 really... i can get by and usually figure it out ... but i'm far more comfortable around the hardware side

#

if i figure anything out with the pi regarding the speaker I will be sure to let you know... it's jumped to the top of my todo list

timber geode Dec 18, 2023, 8:11 AM

#

ah ... one question, perhaps you know:

i bought some PAM8403 - are they of any use in this situation ? i am nearly a complete noob regarding audio hardware ...

peak saffron Dec 18, 2023, 8:15 AM

#

it could most likely be used as a manual volume control. i'm not overly familiar with audio stuff.. but for something like the echo's or other mic/speaker diy device you have no volume control. only if its configured as a media player

#

so that could interface to allow volume control at the minimum

timber geode Dec 18, 2023, 8:17 AM

#

hmmm i was more hoping in getting more umpf out compared to the direct speaker of the seeed mic hat.
the volume control i would do on the software side anyway

peak saffron Dec 18, 2023, 8:20 AM

#

with the pi's then possibly yes.... just need to figure out what its got already. I have no knowledge of configuring pi hardware , this will be my first go. my whole house is esp based

timber geode Dec 18, 2023, 8:24 AM

#

hm, impressive i have to say. the sheer amount of work you must have put in it.
i just went the easy route with zwave and zigbee and off-the-shelf actors

peak saffron Dec 18, 2023, 8:27 AM

#

no i'm fully diy with regards to controllers etc... a few off the shelf bits for touch panels and a couple of bulbs and wall sockets.

#

i have to dash off now... but it was good to have a chat , and i will look more into the pi hat now that its up and running with the basics i can build on it. whenn i get some infor regarding speaker output. i'll drop a message and a ping in this thread
