Je me rends compte que je parle ici de mon émetteur bricolé, sans jamais avoir expliqué comment il fonctionne 😮
Donc voici un synoptique pour comprendre son fonctionnement. Le chef d’orchestre : une #RaspberryPi
Elle commande en SPI un module DDS, qui génère numériquement une sinusoïde. Viennent ensuite deux étages d’amplification, pour une sortie à 20W 😎
La Raspi coupe aussi la polarisation du transistor de sortie quand on n’émet pas, et envoie du +5V pour commander un (éventuel) ampli.

So it seems everyone loved the #PiDay #RaspberryPi @fedora images of #f44 for the #RPi5 as the blog has had well over 3500 hits in 36 hours and 500 odd downloads of the images and we even even hit well up on hacker news! I have a few more things to try and get working before the freeze for 44 as time permits. What do people like the most? What needs polish?

Uh oh... things got a little spicy 😅
I accidentally DDoS'd myself – let's troubleshoot! 🔴
We're diving into Unifi, Raspberry Pi projects, and Zero Trust progress. Expect some cybersecurity rants and Linux shenanigans.
Come watch the chaos unfold! #Cybersecurity #Linux #RaspberryPi

I accidentally DDoS'd myself – you HAVE to hear about it. 🔴
We're diving into Unifi, Raspberry Pi projects, Zero Trust progress, and of course, plenty of cybersecurity rants & Linux love.

I accidentally DDoS'd myself – let's figure it out!
Unifi tinkering, Raspberry Pi projects, Zero Trust progress, and plenty of cybersecurity rants. Linux is involved, naturally.
Watch the chaos unfold! 🔴

I spent the weekend nerding out on my Jetson Nano.
I am working on depth estimation with stereo vision and car detection using YOLO.
The pipeline is a bit slow at the moment, but it is getting there !
