    hmm. the left side makes me think actuator for a morse transmitter, but im sure those cylinders are ginormous capacitors and not simply support posts, and there doesn’t appear to be the range of motion for such a device. But the right does look like an electronic doorbell, so it COULD be a transmitter reciever…. cant get a close enough look at the board to see what it might be.

    It’s actually a Western Union 1880s-era telegraph sounder, connected to a BASIC Stamp microcontroller, and a Russian Cold War era telegraph key.

    What is the BASIC Stamp doing?

    The idea is the BASIC Stamp will pull RSS feeds (via serial) and sound them out the sounder. The key can be used to send commands to it via Morse code.

    Eventually, the idea is to connect a radio, and allow the key and sounder to be used as a speed keyer, with the sounder signalling dots and dashes.

    Ugh! Did you drill through the base of that sounder?!?! I don’t think those philips screws are stock. Please tell me those screws went through holes already there.

    I know better than that. There were holes already in those places for screws.
