    Hi Is it possible include an option to reverse the direction of the encoders? I have two teensybats with encoders that work in opposite directions - very confusing. I know you posted v0.90 in two versions with opposite...

    Hi Edwin Can you clarify where the 100 ohm resistor bodies go between teensy and audio board please. Do the main resistor bodies go between the teensy and the audio board or under the audio board and the main pcb with...

    Hi The build with resistors in data lines looks intriguing. The noise improvement is definite. I am collecting components for a second op amp based build to compare it with my original 1 transistor model so I think I...

    Hi Thanks for that. I am not any sort of expert on analogue electronics so impedance matching is something I don't know anything about. I obviously misunderstood that you can improve impedance matching by simply...

    Hi I have built and am using the 1 transistor amplifier version and running 0.92 with no problems so far. I note that you can get rid of the annoying 23Khz noise peak by altering a resistor to match the microphone...

    HI. Many thanks for posting the short manual. I have been thinking that a manual is a good idea, TeensyBat is getting a bit complicated to carry it all in your head, especially when, like me, your the wrong side of 70....

    Hi AS requested a photo of my build. I use an external PSU, easy to change if it runs out, less electrical noise in the case. Case was one I had spare from a previous project.
