@tsetoras After 7 years of soldering, I got my blood checked for lead, and there wasn't a detectable amount... other friends say that lead accumulates in the bones, but I don't think I'd like to have a biopsy just to check this 😅

@Reelix the tubing is just teflon tube I got separately from the silvered copper wire

[NNNI @NNNILabs]

@AislerHQ and I hope it gets you more customers too 🤪

@DasBoes what scope was it exactly? I have a DS1054Z, and I tried various input frequencies and settings, but I was not able to get a satisfactory XY plot

[NNNI @NNNILabs]

@scribblesonnapk interesting, there are many things I can't imagine doing without a digital scope, but even in 2025 we haven't been able to figure out the CRT's sharp traces among other things

[NNNI @NNNILabs]

@jkadofo for sure! in this case, I would prefer the tactility of a physical model

[NNNI @NNNILabs]

@CNC_Kitchen finally!

[NNNI @NNNILabs]

@MarcoReps is this 20th century TMT 🤔

[NNNI @NNNILabs]

@AislerHQ hotplate got too hot😅

the parts on the other side are fine and the other four boards came out perfectly and work fine

[NNNI @NNNILabs]

@GoldenMuffin69 it's a cap for an ADR1399 reference

[NNNI @NNNILabs]

@MarcoReps heh, fascinating that even static (?) can set it off to some extent

[NNNI @NNNILabs]

@wojtess @AislerHQ something a friend came up with: https://t.co/koLkV4udOp

[NNNI @NNNILabs]

@Alex_Gromoff correct!

[NNNI @NNNILabs]

@Scott_Holmes @DanielBogdanoff scope has been unlocked, can go down to 5ns/div...

since I have three channels running, sample rate is 250Msps, with just one channel it would be 1Gsps, so I'm pretty sure the sample rate of the scope is limiting me...

[NNNI @NNNILabs]

@Scott_Holmes @DanielBogdanoff ah, I see... I don't have that setting luckily

[NNNI @NNNILabs]

@Scott_Holmes @DanielBogdanoff it's not the noise (at least, not in this case, although that would be a nice bonus fix), I'm being limited by the sample rate cause my signals are so fast

tell me more about the 500μA setting 👀

[NNNI @NNNILabs]

@PhillipGoik more of a stupid experiment, only the first capacitor really made any difference

[NNNI @NNNILabs]

@Metaforest 0402 is usually X5R, that is pretty bad in terms of DC bias effects among all manufacturers

[NNNI @NNNILabs]

@MacroWorld21 I don't get you

[NNNI @NNNILabs]

@OnyxCrack supply ripple reduction (which does not decrease much after the first cap)
