fun fact - the SOIC-8 and 0805/0603 TMT breakout boards are the ones I end up consuming the fastest! @aisler.net always provides a quick refill, and gives you €10 off multiple orders with the code NNNI26!

I've made something similar before, but this time I'm getting a custom inner and outer shield made thanks @aisler.net (NNNI26 for €10 off till the end of this year, plus coupon works across multiple orders!)

tell me why I like analog again

this unusual experiment from @aisler.net is yet another PCB capacitor - the outer layers form the driven plate which shields the inner plate formed by the inner layers from interference! (NNNI26 for €10 off similar sketchy experiments!)

@aisler.net actually managed these super thin guard traces! I used KiCAD's solder mask expansion to create them! (NNNI26 for €10 off this year on all Aisler orders!)

oscillators don't, but amplifiers always seem to 😖

the next one is something I've been looking forward to for a while, an open-source DSOXLAN board! github.com/aewallin/DSO... thanks @aisler.net !!! (NNNI26 for €10 off this year!)

first project is a dielectric tester designed by a friend! the idea here is to sandwich a dielectric between the exposed copper plates with a fixed distance between them, and measure using an LCR meter at various frequencies! thanks @aisler.net

I've been gone for 3 weeks and I got no less than SIX packages from @aisler.net ! contents will be revealed over the coming days

anyone see the problem here?

Maker Faire Hannover 2026 Post 3: The number of people who walked by mumbling "Messtechnik..." (instrumentation) and "Hochfrequenz..." (RF) was rather large 💔

Maker Faire Hannover Post 2: @dmytroengineering.com helped me unbrick an MSO-X 3034A! NAND flash corruption is a known issue and repairs are well-documented, but we came up with a method that uses ethernet to load the flash, plus this gives us an opportunity to bypass future NAND degradation!

Maker Faire Hannover 2026 Post 1: I had a blast displaying my projects! However, it was interesting and slightly disappointing to note that the majority of visitors to my stand were old men who had done analog in the yesteryears, very few young people

👀

this is actually such a nice prototyping method

breakout board friday! if you want cheap(er) boards from @aisler.net, use my top secret discount code for €10 off - NNNI26

I sincerely wish those "AI" suckers burn in the deepest depths of hell

NNNI26 for €10 off till the end of the year 👁️‍🗨️

this is now my favourite engineering/science demonstrations

mogged

I love the RP2 but unfortunately even they can't do certain things

off to fab

please tell me there is a way to automate this... I had to do this by hand + kicad's vertical and horizontal distribution tool

used the oven at work with very clean results, board is finally fully populated; next step - programming!

bodges are inevitable 😖

I wonder how reliable this measurement is

so not labelling the parts was a mistake, and making a test board as dense as the final product is always a mistake, so I added more test points! (boards from @aisler.net, NNNI26 for €10 off year-round, multiple times!)

two D flip-flops give me I/Q signals at any frequency (assuming the FF is fast enough, I'm using an 'ACT74)

routing using planes is something I enjoy, especially for power stuff

it's been a few years since I ordered something halfway complicated, but thanks to @aisler.net's rapid registration stencil, it should be easy (NNNI26 for €10 off throughout the year! 😎)

always remember to order a stencil with your PCBs! I tried smearing paste on the board here, but the results were blobby 🤰 (if you get your PCBs from @aisler.net, use NNNI26 for €10 off year-round! 😳)

one of the best moves I've made in the recent past is blocking the uni's "AI center" nonsense, I don't need that slop in my uni inbox every day, please crash and burn

@aisler.net to the rescue with some TMT SOIC-8 adapters! The year 2026 still has 7 months where you can use my discount code NNNI26 to get €10 off multiple times!

modern oscilloscopes are universally pretty meehhh, but the @rohdeandschwarz.bsky.social MXO38 is an exception - compact, dense (I love density), the display is amazing, the UI is ACTUALLY USABLE

hello followers, I would like to announce my exhibition at the Maker Faire Hannover 2026 this year in Hannover, Germany! if you can make it, I'd be glad to meet you and bore you with analog thingies

my long-awaited follow-up article is finally out! nnnilabs.net/trash/2026/0...

attoamperes?

today I'm testing the dielectric absorption test stand

populated some more breakout boards from @aisler.net , bonus picture taken with a microscope (psst: NNNI26 gets you €10 off throughout the year, multiple times!)

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

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

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

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

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

😤

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
