nnnilabs.net @nnnilabs.net · 22/09/2026the 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!) 041
nnnilabs.net @nnnilabs.net · 20/09/2026first 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 071
nnnilabs.net @nnnilabs.net · 19/09/2026I'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 041
nnnilabs.net @nnnilabs.net · 18/08/2026Maker Faire Hannover 2026 Post 3: The number of people who walked by mumbling "Messtechnik..." (instrumentation) and "Hochfrequenz..." (RF) was rather large 💔 020
nnnilabs.net @nnnilabs.net · 17/08/2026Maker 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! 021
nnnilabs.net @nnnilabs.net · 17/08/2026Maker 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 020
nnnilabs.net @nnnilabs.net · 07/08/2026breakout board friday! if you want cheap(er) boards from @aisler.net, use my top secret discount code for €10 off - NNNI26 040
nnnilabs.net @nnnilabs.net · 01/08/2026I sincerely wish those "AI" suckers burn in the deepest depths of hell 010
nnnilabs.net @nnnilabs.net · 30/07/2026this is now my favourite engineering/science demonstrations 010
nnnilabs.net @nnnilabs.net · 28/07/2026I love the RP2 but unfortunately even they can't do certain things 020
nnnilabs.net @nnnilabs.net · 16/07/2026please tell me there is a way to automate this... I had to do this by hand + kicad's vertical and horizontal distribution tool 020
nnnilabs.net @nnnilabs.net · 15/07/2026used the oven at work with very clean results, board is finally fully populated; next step - programming! 140
nnnilabs.net @nnnilabs.net · 28/06/2026so 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!) 081
nnnilabs.net @nnnilabs.net · 19/06/2026two D flip-flops give me I/Q signals at any frequency (assuming the FF is fast enough, I'm using an 'ACT74) 040
nnnilabs.net @nnnilabs.net · 17/06/2026routing using planes is something I enjoy, especially for power stuff 041
nnnilabs.net @nnnilabs.net · 13/06/2026it'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! 😎) 040
nnnilabs.net @nnnilabs.net · 12/06/2026always 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! 😳) 031
nnnilabs.net @nnnilabs.net · 03/06/2026one 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 030
nnnilabs.net @nnnilabs.net · 01/06/2026@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! 041
nnnilabs.net @nnnilabs.net · 29/05/2026modern 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 030
nnnilabs.net @nnnilabs.net · 27/05/2026hello 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 061
nnnilabs.net @nnnilabs.net · 25/05/2026my long-awaited follow-up article is finally out! nnnilabs.net/trash/2026/0...nnnilabs.netThe "AI" Era - The Grit that Keeps on (being) Gritty 020
nnnilabs.net @nnnilabs.net · 15/05/2026populated some more breakout boards from @aisler.net , bonus picture taken with a microscope (psst: NNNI26 gets you €10 off throughout the year, multiple times!) 171
nnnilabs.net @nnnilabs.net · 15/05/2026I 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 062
nnnilabs.net @nnnilabs.net · 14/05/2026the 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 061
nnnilabs.net @nnnilabs.net · 04/05/2026phase one of my LAN upgrade is complete - scope, sig gen and dmm are now all connected to LAN 🎉 080
nnnilabs.net @nnnilabs.net · 03/05/2026being able to RELIABLY read back 50,000 data points is amazing 030
nnnilabs.net @nnnilabs.net · 03/05/2026I 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) 240
nnnilabs.net @nnnilabs.net · 02/05/2026thanks to LAN and sockets, I can run the exact same script on both my PC and RPi 4B with 0 changes 020
nnnilabs.net @nnnilabs.net · 02/05/2026I 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 160
nnnilabs.net @nnnilabs.net · 23/04/2026fun little project, thanks @aisler.net for making this happen 150
nnnilabs.net @nnnilabs.net · 22/04/2026feels like a good time to do some pcbposting, so here's another run from @aisler.net that I assembled using stencil-and-paste, and then a few minutes in the ultrasonic bath to get them super clean 150
