This project was created on 03/02/2015 and last updated 2 months ago.
The Beavis Audio Heterodyne Space Explorer, based on the CD40106 hex inverting Schmitt trigger.
It seems to be finished. I put it all together and it worked fine, except for two pots that occasionally shorted against the lid.
See the updated video link for a really long test drive.
I rest my case (almost).
This poor fruit cake tin already has fourteen holes in it, but I still need to decide where to put the power switch and the output jack.
I'm one knob short. Fortunately, they haven't shut down all the Radio Shacks in this town yet. I wanted to use the 3/4" fluted hex knobs from RS, but they're too short for the pot shafts. I happened to have a single RS control knob, which is a healthy 18.88mm tall. These will leave just enough room for movement.
The current picture is just a teaser. The board is all done except for connecting up the panel mount components of which there are several. Okay, so the board is half done.
I can't remember how many I bought. It probably wasn't enough. I have some 4040Ns and 4051Ns coming soon, and I may use those to add a waveform generator to this project.
I meant to tell you on the other thread--I was in the middle of learning about them on my own by way of the immense resource that is Beavis Audio (see project links) when the Logic Noise column appeared. I couldn't believe the timing!
Modifying an off the shelf baseboard thermostat to add WiFi capability without loosing any other functionality. Cheap.
