So I spent this sunday afternoon doing some field research and soldering in order to be able to drive a #LEGO #train #motor via #ESP32forth using a #L293D motor driver and a nifty #rechargable #9V Lo-Ion #battery that holds a whooping 1300 mAh. I use this to power the #ESP32 (with a #LM2596 regulator) and the motor (via L293D).

And the best thing: the setup works, the code works and yes the motor runs.

Suomalaisomisteinen sipsifirma julkaisi sipsimaun, joka maistuu ... 9 voltin paristoille

Yhtiön mukaan tarkoitus on tuoda takaisin osa siitä "nostalgiasta", joka monella liittyy 9V pariston päihin kielellä koskemiseen.

Leckt Ihr auch manchmal, wenn keiner schaut, 9V Batterien an, nur um zu sehen ob die noch gut sind? Dann gibt es gute Nachrichten für euch. Guy Dupont hat da was entwickelt, so dass ihr nie wieder selber 9v Batterien anlecken müsst.

Today, I #repaired two old #LEGO #Technic #9V #cables, luckily having a suitable one at home. It's not the original color, but that's fine as long as it works. I #extended the #wires significantly.

The #process was straightforward. I opened the LEGO #connector #housing, removed the old #cable, inserted the new one, and then closed the housing, pushed back in the contact pins with a #hammer and an old #screwdriver. lol

I #checked continuity after each connector to quickly #identify any #issues.
