fortune.com/2026/02/24/s... oh my god, why is this stuff not dead yet? stop talking about "holistic AI education" and burn this down already

I nerdsniped @dmytroengineering.com into helping me out with something and here are the results (a friend in need is a friend indeed!) github.com/diminDDL/pic...

adapters!!! thanks @aisler.net! (NNNI26 for €10 off, works multiple times!)

I like this

ready for the next prototype github.com/macaba/TheMa...

did I just say "coilcraft capacitors"? I mean coilcraft transformers 😅

got some PCBs for a small project from @aisler.net the coilcraft capacitors have < 1 pF interwinding capacitance 👀

after further investigation: - the 1 mV step remains unexplained, but I suspect ground current issues - the 100x gain causes the amplifier to slow down by a lot - the 400 ns comparator delay was caused by the large 32 mV hysteresis I seem to have forgotten about

"analog circuits are fun" analog circuits:

shoutout to Coilcraft Inc. for their insane generosity in this age of corporate stinginess

istg this is the last time I'm pulling this trick (using one of the RP2040's pins to signal itself)

the only hope that keeps me going is that I am an adult with €€€ and I can walk into a Five Guys any day

turned out pretty decent, though using solder paste would have saved time and looked even better

the reason the current source looks so small and weird is because I want to cheap out on shipping when I send this out for characterization

I will be testing various current sources - boards from @aisler.net! (NNNI26 for 10€ off year-round 👀)

it's breakout board season😭 (NNNI26 for €10 off at @aisler.net!)

Rapid Registration stencils are highly recommended

is there anything to look forward to in the mid-long-term (20 or 30 years)? I need some motivation ig

@aisler.net 's PCBs under the microscope - the sharpness of the solder mask is amazing (1 mm ruler on the side for scale in the second picture)

first PCBs of the year from @aisler.net are here! 🎉 (NNNI26 for €10 off this entire year!)

happy new year! I hope 2026 is filled with a ton of cool electronics and I have a new @aisler.net coupon code: NNNI26 for €10 off! 🥳

this has got to be my funniest TMT creation

can't have too many of these

what do I do when I quickly need to order adapter boards for a project? @aisler.net, of course! (last two weeks of NNNI25 for €10 off!🤗)

@aisler.net 's amazing PCBs 😗 (NNNI25 is valid till the end of 2025!)

I look at this thing I (re)created and I say to myself "I wish Ronald Swerlein was alive"

does this explain why when asking for help with programming, people get flamed and end up start a tribal war amongst the "experts", who then devolve into personal name-calling, but when asking for help with electronics, 3 EEs civilly discuss ideas and present one unified solution

👀

thanks @aisler.net !

nothing brings me more joy than working on a project

Currency.

I get the new announcement and all that, but does anyone seriously still use Arduino boards or the IDE? (RP2 shill here)

huge shout-out to @gimpofficial.bsky.social, it's made my obsessive scope shot editing possible, pixel-by-pixel (trying to replicate what AoE did, maybe with my own twist) (colours are just me playing around)

have the people who keep recommending FPGAs for fast ADC sampling never heard of the RP2 family and PIO😒 (processing at that speed becomes a question mark though 🥴)

today I embraced chaos and started a new project despite having 39203342 unfinished ones

meanwhile rpi be like: "who wants to buy my cheap chips/boards?" *everyone* "who wants to install my lightweight (open-source) SDK?" *everyone*

just tested the TLV1871, looks like it's a worthy successor to the LM311! the package is a bit of a handful to solder though, but otherwise I love the ±15 V capability and the push pull output

now I can have another shot at testing the comparator... thanks @aisler.net 😋 (NNNI25 for €10 off!)

treats from @aisler.net 😋 (NNNI25 for €10 off)

I made a silly noob mistake and fried a brand new comparator... but that's another chance to redo the board (with input dividers so I can set a threshold!) and send it off to @aisler.net 😋

it never fails to amaze me how uni turns something as interesting as electronics into THE most boring mathematical slop

thanks @aisler.net ! (NNNI25 for €10 off 😜)

this one ended up slightly weird because I want MAXIMUM decoupling for the LT1016 ultrafast comparator

this idea might be a dud, at least the way I've implemented it here... whoops!

the sampling voltage tracker samples voltages and tracks!

another weekend another side project

ddl.red/hate-ai 👀

it feels so nice to finally have a project for parts I've had lying around for ages... I need adapters though, I wonder where to go😏

here's another waveform, I've posted a spice simulation of this before and it's so cool to see this in real life (feedforward pending)
