    I wonder if would be easier to just order a replacement speakjet or have one sent and test that since they are in a socket I believe?

     

    Send the SpeakJet chip back to Albert and he will re-program it.

     

    I've got a feeling the chip's baud rate is slightly off.

    I am wondering whether Richard's 3D print design will work for the first batch of controller kits.

     

    Are the latest boards quite a bit smaller than the first batch ?

     

     

     

     

    Can you roughly estimate the printing cost/volume of used material?

     

    I'll do that. I just need to alter the design to make it a bit stronger first.

     

    It just fitted on the bed of my printer. Took 1 hour 26 minutes on fast print (0.3mm layers).

    Are you saying this is likely a power issue?

     

    Could be. I think it's definitely worth trying.

     

     

     

     

    Run a new wire from the negative leg of C3 to the center post off the audio jack?

     

    Yes. Don't forget, the volume pot on the AtariVox is also being bypassed.

  4. To save power, you could try disabling the amp in the AtariVox. If you're using amplified (independently powered) speakers you won't need it.


    Remove the LM386 (should be in a socket) and tap your amp to the negative side of capacitor C3.

  5. Richard H. wanted to do some 3D printing experiments, as far as I remember. Maybe he can tell us, if he had the time to do something like that.

     

     

    I got side-tracked onto other projects, but I'll be back on it soon.

     

    I more or less finished the top half of the case (see pic).
