Can The Iotiny Be Made Into An Openai Chatbot Connected To ARC?

@Jeremie I agree, there is a little porting tick to make the stock system perform surprisingly well. I didn't try anything like you show above, just a simple box.

So, you can solder an off board amp directly to C11 and use the IoTiny's speaker pins? Where would the amp's output attach to? Are you saying "amplify from the speaker pins" of the attached amp?

ex1: You could solder a small amplifier board's input to C11 and GND and the amp output to a larger speaker (or to the IoTiny speaker up to 0.5W). The IoTiny SPKR pins would be empty in this case.

ex2: You could solder a small amplifier board's input to the IoTiny SPKR+ and GND and the amp output to a larger speaker (or to the IoTiny speaker up to 0.5W). This method would further boost the audio from the onboard 0.3W amplifier, which would be louder but more static would be present.

ex3: Leave the IoTiny speaker as-is on the SPKR pins and amplify the audio the old-fashioned way with porting

@Jeremie Here is what I did in my inmoov. Just a simple box for the 2 ohm speaker. Made a huge difference.

Thanks @Jeremie for the explanation. I tried both your example 1 & 2 on a EZB and did not like the results of #2. Like you said, poor sound and static. I ended up #2 and soldered in a pig tail to the proper points on the EZB board and plugged in a 20w amp to it. Gave booming and clear sound.

Your porting box is a wonderful idea. I can validate that this really works! I did do something like this on a Bradford Exchange Nightmare Before Christmas Cuckoo Clock that I redid the sound system on. When I got it I was very disappointed with both the sound quality and the music it played. However unlike you, I did upgrade to a new small speaker and a new amp. After trying a couple different speakers I ended up using a full range laptop speaker. By doing this it really amplified the sound and had a lot better quality. Here's the link to Mouser and the final speaker I used: Speakers & Transducers 3.2 cm (1.3") fullrange speaker, 150 20000 Hz, 220 Hz, 24-5W

I guess my point is that I used the small space inside the clock to enhance the sound like you are doing in your porting box that you've designed. However, even with the new amp and nicer speaker that I used my sound was underwhelming until I placed the speaker inside the clock.

Here are a couple pictures and videos if the process and result if anyone is interested.

Here is the build video:

@smiller29, Sorry. I guess I kinda hijacked your thread with my project above. I did however want to point to the speaker I used and validate how sound can be enhanced in many ways.

@Dave,  All good man BTW I got this clock for my wife for Christmas so who knows I may use your project!

Well I ended up using the Sound servo (EZB) skill for the mouth on along with a script to control the LED's and it seems to work really well.  There is a link at the bottom to view a video of it working.  I now have OpenAI ChatGPT3 working, Bing Speech, Camera and Face tracking working and it seems to be working very well.   I also did not have to add an amp the I just added a 2" speaker and got the sound output I needed.

The following was the script I used:

# Variables (do not adjust)
# $Soundv4Value = auto
$pwmlow = 0
$pwmmid = 0
$pwmhigh = 0

# Main script
# Set the start point for the never ending loop
:loop
# Check the variable from the Sound servo control 
# against a list of pre-determined levels (you may 
# need to change these) and set the PWM value to suit.
if ($Soundv4Value < 10)
  $pwmlow = 0
  $pwmmid = 0
  $pwmhigh = 0
ELSEif ($Soundv4Value < 20)
  $pwmlow = 0
  $pwmmid = 0
  $pwmhigh = 10
ELSEif ($Soundv4Value < 30)
  $pwmlow = 0
  $pwmmid = 0
  $pwmhigh = 20
ELSEif ($Soundv4Value < 40)
  $pwmlow = 0
  $pwmmid = 5
  $pwmhigh = 30
ELSEif ($Soundv4Value < 50)
  $pwmlow = 0
  $pwmmid = 20
  $pwmhigh = 40
ELSEif ($Soundv4Value < 60)
  $pwmlow = 5
  $pwmmid = 25
  $pwmhigh = 50
ELSEif ($Soundv4Value < 70)
  $pwmlow = 10
  $pwmmid = 30
  $pwmhigh = 60
ELSEif ($Soundv4Value < 80)
  $pwmlow = 20
  $pwmmid = 40
  $pwmhigh = 70
ELSEif ($Soundv4Value < 90)
  $pwmlow = 30
  $pwmmid = 60
  $pwmhigh = 80
ELSEif ($Soundv4Value < 100)
  $pwmlow = 40
  $pwmmid = 75
  $pwmhigh = 90
ELSE
  $pwmlow =50
  $pwmmid = 100 
  $pwmhigh = 100
endif 

# Set the PWM with the value chosen above (you may need 
# to change the port to suit)
PWM(0.D4, $pwmlow)
PWM(0.D5, $pwmmid)
PWM(0.D6, $pwmhigh)
# Add any other PWM ports above this line with PWM(PortNo, $pwmvalues)

# Sleep for 100ms to avoid saturation (you may need to adjust this 
# to increase accuracy or increase stability. Reduce the delay for 
# better accuracy, increase for better stability)
Sleep(100)

# Jump back to the start
Goto(loop)

Hey Dave on your clock mod is there anyway to do it without needing AC power?
