Playing with my new toy:
A finger-sized Digital Logic Analyzer.
It's muselab's one, and it uses Pulseview's open-source visualization software.
👉 8 channels at 24 MHz for 15 €. Not bad!

Browsing through macOS config files, I found a mysterious one called 'com.apple.madrid.plist'.
It turns out that Madrid, the city where I come from, was the internal feature name for iMessage before it went public.
Fun fact of the day 😆

I've desoldered the batteries of my razor and replaced them. Now it's functional as new.
First, I thought of trashing it and paying 70€ for a new one. It would have been a shame since I fixed it for 2€.
In a few minutes, its life was prolonged by ~4 years.
Remember, when it breaks, just fix it 🔧☑️

For the next weeks, I'll be taking a 𝐃𝐚𝐢𝐥𝐲-𝐝𝐨𝐬𝐞 𝐨𝐟 𝐅𝐏𝐆𝐀 🥁🧪
The idea is simple:
As I dive into the exciting field of FPGAs, I'll log my learning journey. Each day, I'll share self-contained project with the contents from the day.
I'll share here and in my GH 👇

I think I finally understood intuitively how Fresnel lenses work 💡
(They're the lenses from lighthouses)
They are very 'thin' lenses, that can bend the light path a lot in a narrow space 🧪

Can you help me make sense of this weird moon shape? 👇🧪
It was sunset. The illuminated side of the moon was facing away from the sun.
I gave it a Google and found that it's called the "Tilted moon illusion" but I couldn't find a visual and intuitive explanation of it.
Moon and sun were at 90°

Random learning of the day 🧪:
In silicon, holes have lower mobility than electrons. To compensate for it, features in PMOS have a larger characteristic size than in NMOS.
For example, look at the transistors (red squares) 👇. The gate in the PMOS is larger than the NMOS (pic from K. Shirriff)

Another antiquity:
While today C is seen as low level, in the times when people were coding assembly manually in worksheets, it was considered mid-level (vs the real low level: assembly)
Plus, it seemed to rival yet another mid-level language called FORTH.

Reading old tech books is very fun. One frequently finds gems like this one:
👉"A question often raised by electronics students is: Why are we learning about programming microprocessors?"
Makes you remember that what's considered common sense today was mind-bending little time ago.

From the new Swift 🐦 website:
"Swift eliminates entire classes of bugs and vulnerabilities by its design"
I wonder if our human-verbal-languages also have, by design, entire classes of incommunicable realities. Not in practice, but theoretically.
The unspeakable.

For the next weeks, I'll be building an 8-bit breadboard PC around the 6502 CPU.
I'm very curious about the interface where software meets hardware!
Along the way, I'll learn about microprocessor architecture, assembly programming, digital design, etc.
The final goal is...🥁 to run Fibonacci!

There's something about nature that makes it very pleasing for humans, and in general, for organic life beings. I wonder if AIs will develop the need to disconnect from time to time in their own little corner of peace.
