After just having responded to the third #curl security report for the evening I noticed a post that cheered me up...

Have a good Friday everyone!

Tested various micros running this program. It derives Pi to 20 decimal places. Interesting stats.

1 N=20: L=INT(10*N/3): DIM A(255): Z$="000000":T$="999999"
2 FOR I=1 TO L: A(I)=2: NEXT I: M=0: P=0: FOR J=1 TO N: Q=0: K=2*L+1
3 FOR I=L TO 1 STEP -1: K=K-2: X=10*A(I)+Q*I: Q=INT(X/K): A(I)=X-Q*K: NEXT I
4 Y =INT(Q/10): A(1)=Q-10*Y: Q=Y: IF Q=9 THEN LET M=M+1: GOTO 7
5 IF Q=10 THEN PRINT STR$(P+1);LEFT$(Z$,M);: P=0: M=0: GOTO 7
6 PRINT STR$(P);LEFT$(T$,M);: P=Q: M=0
7 NEXT J:PRINT STR$(P)

Today I finally started the “real” work on my #RFIDReader project!

The goal is to get this RFID reader that I was gifted by a friend working almost from scratch. I’ll be running it off a Pi Pico with my own #TinyGo code to see if I can get it to recognize cards and send me the data over serial.

First step is to get it powered and hopefully get the LEDs and beeper working before I attempt to read the real data. I’m trying to get both the Pico and the reader powered off 1 USB-C source - so today was the first step on that.

It’s not my finest soldering work, but not awful considering I’m a little rusty. Ground isn’t wired up yet on the USB-C breakout - I need to go grab my wire cutters and grt that solved - but otherwise this setup should work for powering the Pico off USB-C and being able to read serial data off the built in port simultaneously. I did check that I didn’t brick the Pico as soon as I finished the soldering 😅 and it seems to still work okay!

End goal for today is going to be proving that I can do that simultaneous connection with this setup. If that goes well - tomorrow I’ll wire up the power and one of the LED lines for the reader and try and get that working!

It was a rocket day in Minnesota... I have been mentoring the 12 year old son of a friend for almost 8 years, today he flew his rocket on an H motor to 2400 ft, at over 450 mph. This earned him the cerification level 1 and he is now allowed to fly high power rockets.

The beauty of the Fediverse, to me, is our rich diversity of experiences, abilities, and needs.

Everyone brings something unique of themselves into this place, and everyone needs something different from it.

That is a strength, not a weakness. Many come here with expectations that are different from mine ~ on any number of topics: AI, encryption, money, and more.

None of us are “wrong“.. we all just need different things from this place.

And that is beautiful.

I let a Commodore 64 run for three and a half days straight. 87 billion instructions, 303 billion clock cycles, 5.9 million candidate settings tested. It cracked an Enigma message in German without knowing a single character of the plaintext.
