How do I select a transformer for superhet? in c/[email protected]

[–] [email protected] 1 points 5 hours ago* (last edited 5 hours ago)

Sorry for the ambiguity, I intend to use this for audio applications (specifically I want to shift 20 kHz to 100 kHz down to human hearing range, tunable by a pot.)

Given the price and low supply I think I'll go ahead and try to wind my own transformers--thanks for the video, seems perfect!

How do I select a transformer for superhet? (programming.dev)

I've recently been learning about superhet and frequency mixing and wanted to start tinkering. Specifically I'd like to try using two heterodynes in series to first frequency shift then uninvert the original audio, sort of like an analog frequency shifter.

To do this, I'd need a frequency mixer. I've been looking at a ring modulator (like https://upload.wikimedia.org/wikipedia/commons/1/1b/Diode_DBM.png) which should require 4 shottky diodes and 2 center-tapped transformers. I've had difficulty locating an affordable transformer, with good enough fidelity for audio, that also includes a center tap.

I have a few questions:

Where can I locate affordable, good-enough-for-audio transformers?
Is the ring mod approach good enough? I see there's also a gilbert cell.
Any general advice for someone just starting a project like this?

Thanks!

[–] [email protected] 4 points 1 month ago

For a country with a huge amount of land and shore, that makes sense for them. But some form of nuclear (uranium fission, thorium fission, fusion?!) continues to be an important part of the world's weaning off of fossil fuels

For the majority of human history, we've eaten around wood (around a campfire, a hearth, etc), it makes sense it would become intertwined with our food palette

All bark no bite again. That incident where areola put the ball down and Gakpo ran up to it should've been a goal, should've just lashed it and let var figure it out
