Somehow I ended up obsessed with 80s pocket computers. Unfortunately, their weird protocols can make some of them almost impossible to develop for. This project uses the #RaspiPico and no doubt some fantastic use of its PIO, to make a universal interface for a whole lot of them. I need to get a hold of one of these! https://n1ugk.com/2025/12/pocket-computer-universal-interface/ #vintagecomputing #retrocomputing

Pocket Computer Universal Interface

I began development of a Universal Pocket Computer Interface for use with Sharp, Casio, and Texas Instruments pocket computers and graphing calculators.

Erstkontakt leider erst im für den Jahrgang letzten Unterricht: Controller programmieren mit schlankem Toolset: Linux, #MecrispForth auf #RaspiPico.

Made a lil frequency sweeper in #rustlang for #RaspiPico to see resonant frequencies of components. It works, mostly?

#raspiPico im Einsatz: Blitz-Steuerung als Teil der Wettermacher-Station in 5 Wochen Kindertheater „Thalia-Fasching“.
Beim nächsten Mal gibt's eine schickere Box. 🙂

„Zeus' Wetterküche“ ist Teil des aktuellen Kinder-Mitmach-Theaters am #thaliaTheater in #halleSaale. Seit mittlerweile drei Wochen sorgt ein kleiner #raspiPico dabei für die angemessenen Blitze der Gewitter-Installation.

Problem with low power timer for #Arduino & co:

In case anyone has the same problem - we use the little TPL5110 based low power board by #adafruit to drive a #RaspiPico, and this does _not_ turn on in a stable manner each time the timer is triggered. We guessed that the pico has a cap at the supply which draws too much peak current turning on. I now tried the super elegant solution of putting a 1 Ohm resistor in series with the #RaspiPico, and voila, it works just fine ;)

The official reference manual for the RP2040 says that the I2C protocol was originally defined "in the Dead Sea Scrolls" and gleefully declares the PIO peripheral to be Turing-complete after showing that it can add two 32-bit integers in under a minute. Basically the whole thing reads like 20something me wrote it, and I'm here for that. #raspiPico #rp2040

Leider viel zu schnell zuende: zwei Tage Programmieren lernen mit Mikrocontrollern an der lokalen Medienanstalt mit netten, aufgeweckten Leuten und (fast) nur freier Software. Im Tohuwabohu habe ich ganz vergessen, mal Fotos zu machen.
