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

The cookie-to-business-card ratio at Maker Faire Hannover was perfect. Lovely to meet so many of you at the HCC. Waves to @blinkyparts.bsky.social, @nnnilabs.net, unsurv, Freie Maker, and the Infineon folks. #MakerFaireHannover #MFH26 #electronics #PCB #maker

this is actually such a nice prototyping method

The current progress on the RC car project: Transmitter has two working oscillators and working summing amp. I used 2xAA batteries as a 0V reference (buffered) to create a +-3V for it. The 555 oscillators are 6V-0V. Then ac-coupled. Modeled it first in LTSpice, this is working out quite well.

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

They can if you think about the architecture of the underlying computer a bit harder 🧌

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

just like the render (jumped the gun on the inductances)

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! 😳)
