Making A Mini AM Transmitter Better
The chances are that many of you will have made an FM “bug” style transmitter, a simple one-transistor oscillator usually driven by a small electret microphone. It’s also relatively straightforward to do the same for AM, and if you take a look through AliExpress you’ll find some modules which do just that. [Doz Television Workshop] has one, and he’s treated us to a thorough run-down of its design before addressing some of its shortcomings.
An AM transmitter is simple enough, in this case an oscillator and buffer driving a class C power amplifier. The modulation is applied by a transistor in series with the power amp, driven from an audio amplifier. Some attention has gone into the design of this one, with a proper output filter and plenty of room for tweaking to achieve proper levels and modulation density. There are some problems though — The modulator transistor is mounted upside down for the heatsink, and the frequency stability leaves something to be desired. [Doz] fixes the heatsink mounting and incorporates a DDS frequency synthesizer with an Arduino for control.
More after the break…
The resulting transmitter is better, but there’s still a problem. The limitations of AM broadcasting demanded both limiting and pre-emphasis, which he applies in software through one of the more powerful Teensy boards. We have to admit we’d have tried to do the job the analogue way, but that’s merely preference.
This board looks to be a good solution for an AM radio collector wishing to use their sets in an age of declining AM transmission. It should be legal under Part 15 for Americans, but as he points out it’s not for Brits. We suspect such a low-powered device wouldn’t attract adverse attention though. The video is below the break.
If you don’t need so much quality, it’s possible to do the job in a much less elegant manner.

Well it's my 23rd birthday and didn't realize when I open my 'create a note' it shows up confetti 🥳... God I love this software, Going to have to see if I can learn the code base behind it and add my little improvements that I've always wanted.

Sweet Yoba, I pushed my ActivityPub patch to production.
I'm not even going to test it yet. I'm too tired and probably scared. I'll just leave it overnight and see if it catches on fire or something.

"...the CDC is working with us... That's not a negative..."
also, mentions TWICE that people can get back to work quickly after they get treatment. Well, thank god for that, our nation's most important priority.

Da neo abbonato del Post posso ascoltare i podcast ed io lo faccio in auto
Ho trovato di particolare interesse l'Ep. 87 di "Amare parole" di Vera Gheno dove ho scoperto che conosco termini che i neolaureati citano a memoria senza sapere però il significato.
E puntualmente la Prof.ssa Gheno li smaschera...
@paoloparti quando mi sono abbonato al Post non sapevo del fatto che i podcast, che prima non ascoltavo, sarebbero diventati un bonus per gli abbonati.
L'ho scoperto poi, quando ho visto che con l'app li potevo sentire in auto; non mi sono abbonato per i contenuti extra o eliminare la pubblicità, ma per sostenere un progetto editoriale equilibrato che mi soddisfa.
@paoloparti d'altro canto è come su Mastodon. I pochi che fanno donazioni tengono in piedi la baracca.
Anch'io ci ho ragionato 🤭
Chi si abbona al Post li aiuta ad offrire molti contenuti a chi non si abbona, ma i conti devono tornare e senza soldi, la baracca non sta in piedi.
E' anche vero che a molti (non a me) serve uno stimolo (vedi bonus) per abbonarsi.
Quindi delle due, l'una: o la pubblicità o l'abbonamento. Potendo, ora, meglio la seconda opzione.
Got this done on my livestream today. It's an illustrated "polyptych" referring to the folktale, Sleeping Beauty.
It was done entirely in Procreate, with no AI.

And you can also watch the three livestreams it took me to complete it here:

I'm really loving these images inspired by Margaret Macdonald Mackintosh and the Glasgow Four. I'm finally starting to feel a bit more confident in the process and torquing it toward my own sensibilities. I'm having so much fun!
Next up is either Goldilocks & the Three Bears or Little Red. Haven't made up my mind which one yet. Woohooo!!
