NNNI

populated some more breakout boards from @aislerhq@aisler.social , bonus picture taken with a microscope

(psst: NNNI26 gets you €10 off throughout the year, multiple times!)

okay so now I have like a very expensive clock

feels like a good time to do some pcbposting, so here's another run from @aislerhq@aisler.social that I assembled using stencil-and-paste, and then a few minutes in the ultrasonic bath to get them super clean

fresh set of PCBs from @aislerhq@aisler.social
more to come

the HMC8043 completes my all-LAN all-SCPI setup! to celebrate, I wrote a script that loads a few useful voltage/current configurations without having to fiddle with the front panel controls

I just realized that my new signal generator has adjustable rise and fall times, so here's a demonstration of I/C = dV/dt using a 10 nF / 1 kΩ highpass filter

phase one of my LAN upgrade is complete - scope, sig gen and dmm are now all connected to LAN 🎉

I finally got myself a 34410A! I impulse-purchased this because:
1. it has a multislope IV ADC which I've always wanted
2. it has LAN, so the first step towards converting my bench to LAN + SCPI

JFETs are underrated

the restorative power of good anime is highly underrated

I played with the 34410A for the entire day yesterday and scripting for it is so painless

here, I measured the RMS noise at different NPLC settings and compared it to what it should "ideally" be (decrease with sqrt of integration time, normalized to lowest NPLC)

thanks to LAN and sockets, I can run the exact same script on both my PC and RPi 4B with 0 changes

fun little project, thanks @aislerhq@aisler.social for making this happen

I swear to god, no ulterior motives!

being able to RELIABLY read back 50,000 data points is amazing
