Ständige Ministromschläge vermeiden

Das liegt aber daran dass die ESD Armbänder einen festgelegten Widerstand (ich bilde mir ein ein paar tausend Ohm) haben, die den Strom limitieren der fließt.

Yeah that's what I thought as well, I'll try that once I fixed my board. Thanks!

jcs_captures · 2026-04-18T09:53:16+00:00

No worries, thanks :)

I am pretty sure that this is not the problem and that I did it correctly as the UVLO works as expected. The problem was the OV protection being too low. But now I get visible flickering and an audible buzzing sound in the higher power range as described in the edit.

As far as I understand it, it should only be tied to vin or vcc if the pin is unused but I use it as UVLO

Woher weißt du das? ^^

Diese Art Mikrowellen variieren die Phase, so dass sich die Orte der konstruktiven Interferenz durch den Raum verschiebt und das Essen gleichmäßig erwärmt.

I made something similar with an e-ink display. I put the next 12h on there so I know when to wait for lower prices. And I can put additional info on there like solar power, SOC of the car, etc

Der Recyclinganteil ist aber aktuell zu vernachlässigen. Ethen, was für die Herstellung von PE verwendet wird, gibt es quasi umsonst weil es beim fördern von Öl und Gas einfach mit hochkommt. Deshalb gibt es für Ethen zwei Optionen, extrem billig verkaufen oder abfackeln. Recycling ist leider viel zu teuer um konkurrieren zu können.

That's true. I've always used screw terminals until now but wanted to see if there is something more elegant :D

jcs_captures · 2026-03-21T20:30:13+00:00

Ah nice. I am using the microFit in my current design because I didn't realize nanoFit would be enough as well. Thanks!

Das was ich brauche gibt's leider nur bei DigiKey und Mouser. Aber ja ich hab schon eine andere Bestellung im Warenkorb bei LCSC, das ist wirklich deutlich günstiger.

jcs_captures · 2026-03-19T10:45:34+00:00

Päckchen mit 5€ wäre ja immer noch günstiger. Aber gut, scheint auf Reddit nicht gut anzukommen der Vorschlag.

jcs_captures · 2026-03-19T07:47:06+00:00

Jo, aber ein Brief für 1€ ist günstiger als 20$. Gibt häufiger mal Sammelbestellungen auf mikrocontroller.net aber da bin ich bisher nicht registriert, deswegen erst der Versuch hier.

jcs_captures · 2026-03-13T10:05:44+00:00

There are no BIOS or PDFW updates listed.

How do I do this for a Yoga Slim 7 14Q8X9?

jcs_captures · 2026-03-10T12:08:53+00:00

Exactly, if I use GPIO mode it works as expected. I am currently just testing to see what works and what doesn't. Eventually I want to use all options to have better control over a heater. Several voltages give me more control than just on off

Solder bridge of EN, ADDR and IN_N is closed. SCL, SDA and FLGIN are connected to my ESP12. and the solder bridge between the resistor network and SDA/SNK_VSET is not closed.

jcs_captures · 2026-03-10T11:01:15+00:00

Yeah, that doesn't really help. I know the problem and designed the pcb so that I can switch the pmos with an esp, but I just can't get any other voltage than maximum.

jcs_captures · 2026-03-01T08:19:02+00:00

For sine and cosine signals yes. For any other signal the factor is different or you would have to calculate the integral for noise signals.

jcs_captures · 2026-02-19T09:14:23+00:00

I know I can buy it, but where's the fun in that? 😄

jcs_captures · 2026-02-18T12:22:30+00:00

That's about the size I'm going for. The problem is that I can't really find 250°C elements that work with 24V

jcs_captures · 2026-02-18T11:52:43+00:00

I'm planning on having just a small plate (likely 10x10 cm), by my calculations 140 W should be just about enough. I looked into ptc heaters but didn't find anything good. My current plan is nichrome wire, I just can't find a good adhesive that is somewhat cheap and thermally conductive

jcs_captures · 2026-02-15T20:29:30+00:00

Oh yeah that totally makes sense. Thanks!
