Fast zum halben Preis

Amazon bietet aktuell die Doppelpackung des Shelly RGBW PM für 27,75 € an, kaum mehr als das Einzelpaket für 26,00 €.

Wer sich also für 12- oder 24-Volt-LED mit einem Vierkanal-PWM-Dimmer für 4 Einzel- oder kombinierte RGB- oder RGBW-Kanäle eindecken will, bekommt das aktuell kaum günstiger.

Ich hab mich nochmal mit 4 Stück eingedeckt, um die 24V-Hausanlage mit Home Assistant zu komplettieren.

Endlich, jemensch der #mitDenken't!

Da hätten wir eine tolle #COOPdesigne Aktion bei der wir befruchtendes PingPong betreiben könnten.

Erde ist Minus, ein Pluspol wie im Bild 12v, der zweite kann dann #24V sein. Minus ist gleich. Wenn eine Nase des Steckers abgefeilt wird und die betreffende Nut in der Dose zugePoxipol't
passt's.

I took so much power from our solar batteries that not only did the batteries go into protection mode for 30 seconds but it doesn't know the %

For context I was using a uk induction stove at 2kw even though we don't have enough 12v batteries to support it in this realm

@jasoncoon great suggestion with splitting the channels to multiple pins. After a bit of fiddling with the code and piecing together examples I got three letters on different pins of the rp2040 feather (will add more tomorrow). Thanks to Jason's handy dandy Pixel mapper, I mapped em so rainbows go from top to bottom an side to side of the letters.

I think those residual flickers are from the crappy connectors. Still not sure where to get good LED strips. 3 and 24 VDC is way more persnickety than 8kvAC :)

Time for bed now. Sooo much neon to bend tomorrow and LEDs to program.

@realkrzysiek Do #notatnik:

Ponieważ nie dysponuję popsutym zasilaczem Dell-a żeby wygrzebać tę linię danych, skłaniam się do przejścia na ładowanie z USB-C. Ale by było uniwersalnie, #DIY i bez kupowania "gotowych" zasilaczy za milion monet, znalazłem płytkę z przetwornicą i procesorem, która ma szansę dostarczyć te 60W w standardzie PD, gdy będzie zasilana z 24V (w moim przypadku dokupienie drugiego #akumulator-a żelowego, co i tak planowałem).

Electric Wheelchair Dump Truck Hack Really Hauls

Have you ever looked at a derelict electric wheelchair and thought "I bet I could make something great with that!" Of course you have- this is Hackaday, after all! And so did [Made in Poland], who managed to get a hold of a broken down electric wheelchair and put the full utility of his well equipped metalworking shop to work. The results? Lets just say it hauls.

What we really enjoyed about the build was that there wasn't much that couldn't be done by an average garage hacker with a drill press, angle grinder, and a stick welder. While it's definitely nicer to have a lathe and a high quality welding table, plasma cutter, and everything in between, nothing that [Made in Poland] did in the video is such high precision that it would require those extensive tools. There may be some parts that would be a lot more difficult , or lower precision, but still functional.

Another aspect of the build is of course the control circuitry and user interface. Keeping the skid steer and castor approach meant that each motor would need to be controllable independently. To achieve this, [Made in Poland] put together a purely electromechanical drive controlled with momentary rocker switches and automotive relays to form a simple H-Bridge for each motor.

Of course you just have to watch until the end, because it really proves that a man will do anything to get out of hauling wood around! Old electric wheelchairs can also make a great base for big robots, as it turns out.
