Cobra 148 Digital Display


There's a .96" RGB OLED display available. Not surprised they didn't put that in the kit, though. Costs a few bucks more.
 
For giggles I went back to the site and tried to order a kit. Couldn't find a link to anything I recognized as a "shopping cart" or "checkout". They may not sell to the US, or it could just be that I can't read Portugese.

You can, however, download all the firmware as hex files and install it on your own arduino board. You can find that here: http://kitdds.blogspot.com/

Well, color me embarrassed.

I totally missed Adafruit selling a module with the Si5351 chip installed and ready to hook up.

You should be able to put together your own "kit" from an Arduino pro-mini board, the above-mentioned "clock oscillator" board, encoder and OLED display.

He shows the hookup in the PDF.

The file to download into the Arduino is apparently the binary only, and not the source code.

Bummer. Would save me trouble. But I'm thinking Browning Mark 4, Mark 3, etc here.

Kept procrastinating a setup with the AD9851 DDS chips from Chinabay.

But hacking this setup for the old tube radios looks less intimidating.

So far. Ordered a few of the Si5351 boards from Adafruit. Already have some pro-mini board, and the serial interface to program them.

Pretty sure you'll find the whole shopping list at Adafruit. Didn't search for the stuff we already have on hand.

No more excuses.

For now.

Source code would have been nice. Too lazy to learn Portuguese to ask him if I can have a copy.

Aren't OLEDs prone to early failure by design?
Sure I'd read that somewhere . . .

Couldn't say as I don't keep up with materials science. I can say Apple uses them in their iPhone X series. Which doesn't tell you anything about this application.
