    Aw shucks, thanks, mate!

    I'm even considering an adaptive output, so no matter what type of headphones you use, the volume level will be "correct", and the volume control range will work to provide roughly the same range of loudness. So folks with high-impedance (>600R) phones, who would normally not hear well at all, could be accomodated as well as more "professional" phones (4,8, 16, or 32 ohm). It's not a lot of extra circuitry, but it's probably overkill for this right now. Regardless, I'll be designing something very similar for my own detector...

    Um, I've struck a problem. My Arduino has gone up in a puff of smoke (quite literally). I have no idea exactly what happened, but I think my star ground point shorted the onboard USB regulator, and immediately the ARM-3 developed a hot spot and is dead as a doornail. There goes $61.06 that I didn't need! And because it's my fault, it's not covered under warranty. (Oh, I suppose I *could* claim that it was DOA, but that's not how I do things in the open source community).

    So I'm stuffed until a replacement arrives, hopefully early next week. It would be sooner, but everyone seems to have run out of stock of the genuine Due! So I'm getting a very well-designed clone (slightly different features) from Hong Kong. There's another delay due to Paypal, it always takes a few days to clear out of the cheque account... But I'm hoping either by the weekend, or more likely early next week.

    I can't even work on my own design... And I'd just got the Stingray hooked up. Grrr...

    I'm sorry about the delay. I wasn't expecting this of an experimenter's board, but there you go. Too many electrons in the wrong place.

    I'll shoot an update as soon as I've got the new module working. I'm still going to tinker (pardon the pun) with the circuit for the audio, so all's not completely lost, I just won't be able to test stuff for the time being.

    My apologies,
    Pete

      Hope it gets dispatched before 4th Feb (start of the Chinese New Year). All factories will be closed until 16th Feb.

        this is sad to hear.
        When experimenting little smoke is usual anyway. This is why I like to experiment with cheap 8 bit PIC-s and always order more of them than nessesary. Some PIC-s have died too because of my connecting error, but then it is only about 1-2€.

        Do not give up because of this little setback!

          Pete,
          once you start again, just make sure you check the Don Lancaster's "Magic Sinewaves" as an approach.
          There are some other very simple approaches too, but they involve multiple PWM outputs simultaneously.

            Thanks guys! I've been assured by the HK distributor that the parts were shipped prior to CNY.

            Oh, and Happy year of the Snake to everyone!

            -Pete
