Ik zit meer in het Suske en Wiske kamp. Koop ze nog wel eens bij de kringloop om mee te nemen op vakantie.

Yes, the reason it feels like a gimmick is that there’s so much to be gained in other important (safety related) areas. Probably not sexy enough.

Why no (buffer) chip or something?

I've never understood this fascination with full self-driving cars. Nice for about 80% of orderly roads, forget about most downtown European cities. Driver assist and other car tech innovations are more important I think. That said, I couldn’t imagine reusable rockets to work either.

Investeerders maar vooral ook kleinere ondernemers die hun opgebouwde appeltje voor de dorst willen stallen voor later, durven niet meer te verhuren. Tijdelijke huurcontracten mogen niet meer dus als ze willen verkopen dan moet dat in verhuurde staat. En dat brengt zo’n 30% minder op.

Idd een vak apart. Ervaren prikker helpt.

Understand. My shack is small too so I went with the FT-710 which has all the bells and whistles. I did look for vintage at start but good old equipment can be very expensive and still lack some modern features.

I have an old o’scope in my lab and love the looks of it, not for practical use. Guess it would be the same for an old radio. I would love to have one for the looks and occasional play.

I sometimes use the product selector to see what chip version to use: products.espressif.com#/

The ESP32 chip series includes the ESP32, ESP32-S2, ESP32-S3, and ESP32-H2 which support the hardware Pulse Counter (PCNT) peripheral.
Also see for c3 there is no pcnt: github.com/espressif/ar...

I don’t know what you’re doing. What is the relation of a light measurement unit (lux) with a pulse counter?

Yes, no easy task sometimes. It takes a lot of time.

tommyjones.bsky.social @tommyjones.bsky.social · 6d

Here’s a general version of my code. It’s an early version and I probably tweaked it but perhaps it helps. I avoid libraries where possible to be able to maintain my code and to know what’s going on.

Are you talking about a “Post Processor” of a CAD program like Fusion 360?

tommyjones.bsky.social @tommyjones.bsky.social · 6d

Why difficult? Some ESP32’s have a dedicated peripheral for it. The PCNT module. I used it for the frequency counter for the Power Nanny. It handles frequencies up to 30 MHz.

I used this hack on my MPCNC for years and it worked flawlessly without loosing its shape. But for the new CNC with thicker cables I needed to switch to real drag chains.

Nou, ook vaders hebben dat knagende onrust gevoel hoor. Hopelijk snel een telefoontje na de landing.

Ah, dat is dan weer jammer. Maar hopelijk heeft moeders dampo recept geholpen.

Beterschap. En ik ben ook een dampo gelovige. Maar meer voor als m’n keel/longen symptomen vertonen. ‘S nachts flinke laag dampo op keel en borst met een t-shirt erover en (belangrijk) een sjaal om de nek.

Misschien naïef, en ik heb me er nooit echt in verdiept, maar ik vraag me soms af waarom we geen kunstmatig eiland vliegveld hebben net als Japan.

Scratching your own itch works best. It’s what drives my little projects too. And sometimes it turns into something useful for a wider audience (as a nice bonus).
