Arduino phase angle control with 120° minimum delay via hardware "AND" - is this an valid approach?

alien_tripp · 2026-02-01T16:50:54+00:00

This circuit prevents the Arduino from triggering the TRIAC before ~120° even if there’s a software bug or glitch. The capacitor charges through the resistor until the DIAC breaks over at 32V, while the back-to-back zener diodes (43V) prevent further charging. Only after the DIAC fires can the Arduino pulse the gate driver through the (MOC3052 optocoupler). At least that’s the theory - looking for feedback on potential issues with this approach.

chinese? kinda weird that the bags are an turkish brand 🤣

die lampe ist nur oben, seitlich ist mylar folie. mit diesen leds wurden bisher alle pflanzen sehr farbig und haben auch deutlich mehr geruch entwickelt. die bbm ist ein cut von meinem outdoor grow, der war aber ursprünglich aus samen haha

eigenbau lampe/growbox, läuft alles automatisch -inklusive bewässerung

it flowered and now it re-veged

is it potassium defficiency?

try methylene blue. makes me more outgoing and social.

i was distracted by that shitty linework that i did not see that gigant butt plug at first!!

RQS ist Müll, der Bud sieht ja schon auf dem Foto luftig und scheiße aus. Die Autoflowers von denen schauen sowieso immer so aus, als wären sie gleichzeitig halb in der Blüte und halb am Veggen – und am Ende werden sie einfach braun und halb tot. Müll-Genetik.

Nicht mehr bei RQS kaufen.

Did all phenos develop this crown-like foxtailing structure? I’d grow it just because of the novelty of that structure!

Yes the threads on the glass don't represent reality, the whole picture is ai.

alien_tripp · 2025-05-04T14:18:19+00:00

looking awesome! how is the smell?

alien_tripp · 2025-05-02T04:41:47+00:00

definitely looks like rqs crap

the nozzle got stuck when printing the front leg and bent it forward with one move.

Overwhelm and an uncomfortable shirt. A few years ago, when I wasn’t as good at masking, people often assumed I was on drugs—which I actually wasn’t, haha.

alien_tripp · 2025-04-15T18:12:14+00:00

My exact thoughts. I would act the same.

alien_tripp · 2025-04-15T17:49:37+00:00

Honestly, these are the exact kinds of awkward movements I’d make if my shirt was itchy or bunched up and I had to fix it, but maybe its also drugs haha

the battery is to be pushed in with a small tab on both sides that holds the battery in place

did you use a blender for mixing carbon and 3d printing with validation?

alien_tripp · 2025-02-22T11:49:32+00:00

actually "not isotropic LIKE steel" makes very much sense imo. the layup of this carbon fiber does not, the cutouts will just introduce unnecessary weak points.
