Yep, this is not the AI Revolution we were sold. Remember, the one that would solve globally critical issues like cancer and climate change? The world was not on the brink because of programmer productivity .. but hey, since that's the only nail it seems good enough for, then hammer away!

LEAP#162 LM2577S/LM2596S Boost/Buck Converter Module A quick test of an LM2577S/LM2596S Boost/Buck Converter Module, with a fresh look in 2026 to verify its current control behaviour and mount it in a laser-cut case.

I took a fresh look at the specs and behaviour of this buck-boost module and laser cut an open case for better mounting

Swan Lake: love demands truth, loyalty, and moral clarity - and even a moment of deception or weakness can have devastating consequences.

This week's @cassidoo.co challenge: find the maximum sub-array sum. Using #lua this time.. and realising this is probably also a proof for the sunk cost fallacy!

Nakajima A6M2-N beached with the help of two ground crew in the water as the pilot stands in his seat looking on. a Couple of palm trees provide some shade for a small lean-too on the beach with perhaps the promise of a cool drink

Nakajima A6M2-N making a pit stop on an isolated Pacific island. A very old ARII kit, but great fun for a little dio.

They'd rather invent an entire mythology of "Western Civilisation verses Big Bad China and Non-white People of a Certain Faith", than just deal with the consequences of neoliberal capitalism gone wildly off the rails

Side-quest: who on earth is using an 8" floppy as an icon?? That's even more retro than the 3.5" I see most of the time!

thanks, happy you like it😀

Even more annoying for those of us who travel rarely, and have not had a British passport since forever. Think I'll just cancel all plans of visiting the UK until the home office fixes this (it's not a policy or legal issue, just short-sighted design of the new ETA system)

"Annoy" is putting it mildly!

cheers Roberto!

LEAP#833 Solving cassidoo's moveNums on Arduino Using an Arduino to interactively solve cassidoo's interview question of the week (2026-02-09): using a rotary encoder to enter an array on an LED 8x8 matrix, dial-in a target digit on a 7-segment dis...

Another solve for this week's @cassidoo.co challenge: this time with an #Arduino and LED matrix to animate the in-place moveNums algorithm🎉

Making the US less attractive for migrants (or tourists, or non-billionaires), one stupid decision at a time.

Er, mystery? Lanzhou is a hub for lots of AI unis, labs, conferences, and startups. Singapore also. Smells like AI just doing AI stuff

This week's @cassidoo.co challenge: rearrange an array to push all the matching numbers to the end. Using #factor this time and it turns out ideally suited for solving this as a one-liner.

Takes alot to get me excited about AI these days. But now I'm hoping MSFT will just buy AISLE and stick it in GitHub (and fix their Windows release pipeline while they're at it)

I recently updated my HamClock on the Raspberry Pi with BME280 sensor and alarms.. only to learn of the project's sad demise. Still working as of now, but updated my notes with some promising alternatives..

Singapore Airshow 2026. I'm trying to take my own pics, but don't think I can better this. The F16 & AH64 display is something else! I've seen it before, but in HD it is AWESOME! This doesn't get old;-)

fyi, just got this running on Ubuntu. Couldn't get PICkit 3 to work on my latest macOS, so I script sending the hex to linux and flash the pic there😂 Inconvenient, but works while I dig deeper on the macOS/pk3 issue! leap.tardate.com/pic/gettingb...

Updated a few projects to MPLAB X IDE 6.2.0 - the last rev to support PICkit 3. Sadly seems PK3 no longer working on macOS (win/linux OK). For now I'm using a script on macOS to send the hex file and program the PIC remotely on Ubuntu! Anyone with PK3+macOS advice?

The President of the United States and the dumbest motherfucker on Earth should be two different People

Yes they should.

"suspect" is the word😆 Only detail on the schematic I'm not sure of are the actual winding details of the transformer.

hmmm, good question. Measured and HV out seems fully floating, perhaps due to C2. Checked and if I connect HV-LV grounds, HV+ out remains the same but now referenced to input ground.

Thanks, I missed that. It's in the seller notes that I quoted verbatim, but I'll fix it for accuracy!
