Youβll find a 555 doing that in the spindle motor control on cheaper cnc mills among other things. Two diodes, a variable resistor and capacitor plus the 555.

Good afternoon from downtown Chicago, where despite heavy snowfall, thousands have gathered for an anti-ICE/CBP demonstration in solidarity with the Twin Cities. More are still streaming in.
Lt. Illinois Gov. Juliana Stratton just addressed the crowd, and called for ICE to be abolished.

A cartoon of a news report. The picture shows a government official doing a press conference flanked by goons.
The headline reads βA man attacked federal bullets with his bodyβ
Underneath the picture is a quote saying βthose bullets had familiesβ

There is far more outrage from tech leaders over a wealth tax than masked ICE agents terrorizing communities and executing civilians in the streets.

The rise of the right had left me sickened and withdrawn for some of the previous year, so I tried to stop reading the news. But to be honest - it's in my face. People I work with, rely on, spent time with are being threatened and hurt. WE need to get off this dark path.

I want to remain talking about robotics, 3d printing, Lego and so on. But what is going on in the world has me increasingly concerned. The US appears to be turning into terrifying right wing dystopia, and the far right in the UK (through Reform) are trying to follow suit.

If you were computing in the 1980s then these books were a must! Still have my originals from back in the 80's when I started with a #ZXSpectrum.

Now that's an interesting challenge. Perhaps I could tame it to 52 robot projects in 52 weeks - where "project" means improving/fixing an existing robot as much as getting around to building a new one from my parts stores?

Childish drawing of a tubby dragon riding a motorcycle. Drawn in a combination of felt tip pens, and pencil crayons.

Use them as part of a "shonky" filament system to try keep them dry? At least until i get a "real" filament drying system - lots of dessicant with the filament in the enclosure.

In 2026 that I still find it crazy that schools send word documents in emails, and fail to put actual content in the email.
Often, that word document has less than 4 paragraphs of text - it really could just be email body. Sort out teacher digital literacy in the UK!

Smart Robot Localisation with Python and Raspberry Pi
Last week, I managed to build a python 2d robot physics simulation using PyGame and Pymunk - something I wanted to do for year. I connected it to the code I'm building for Learn Robotics Programming 3rd Edition - I think the result is pretty cool. www.youtube.com/watch?v=XbNH...
