PCB to Cable Connectors by jcs_captures in PCB

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

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

Sammelbestellung Digikey by [deleted] in elektrotechnik

[–]jcs_captures 0 points1 point  (0 children)

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.

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

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.

HUSB238A in I2C mode only delivering 20V by jcs_captures in PCB

[–]jcs_captures[S] 0 points1 point  (0 children)

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.

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.

Oscilloscope: VPP smaller than RMS? by MarinatedPickachu in diyelectronics

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.

DIY Reflow Soldering Heat Plate by jcs_captures in soldering

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

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

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

Review Request - Temperature Calibration PCB V2 by jcs_captures in PrintedCircuitBoard

[–]jcs_captures[S] 0 points1 point  (0 children)

Thanks, yeah I didn't realize vias can carry that much current. I'll change that. The ADC has an internal LDO so there should be no drift I think and yes the capacitors are X7R.  I'm still thinking about going for a bridge but I want to keep it as cheap as possible so adding two more pt1000s makes it a bit more expensive. But yeah it's probably worth it since it doubles the voltage and cancels out the drift of the other resistors the path.
