So interesting.

Plastic dome with sensors and wireless hub.

Been working on this (in spare time) for nearly a year. Finally finished. Evaporation sensor system. Wireless hub foreground. Microcontrollers in box on left. Motorbike battery powers fans inside dome. Intended to help get a better understanding of factors that affect environmental evaporation.

I once shared a lift with David Boone in Launceston.

Socialist Realism at Posts and Telecommunications Institute of Technology.

In Hanoi for IEEE ICOIN. Interesting place. Venue is PTIT.

Thank you.

The link isn’t opening. Could you post the reference please?

LOGICOMIX: An epic search for truth.

This is worth a read. Talks about Russell, Gödel and others who worked on foundations of mathematics.

Christchurch

Christchurch for IEEE ITNAC. itnac.org.au

Yes. A great injustice.

First Sparks album I bought.

I’m guessing he’s talking about a comms network with a fibre optic core and Ethernet access.

Zone E contains the Australian state of Tasmania.

E but only because of the Tasmanian scallop pies.

Thesis is that population stabilizing more quickly than projected and for many countries will soon decline. Don’t recall “scarcity” but says reduced population should make some problems easier to address but new ones will emerge. Interesting read but not a demographer so can’t comment on validity.

Cover of book “Empty Planet”.

Really interesting.

Always something interesting in IEEE Spectrum bsky.app/profile/spec...

Katie Mack “The end of everything”.

A fun read.

Nice cafe near hotel.

Beautiful place Mallorca. Sadly came down with a cold on the way over and spent most of my visit asleep in my hotel room. Nice hotel.

I have so many backpacks I don’t know what to do with.

Certificate saying I’ve presented a paper at Edulrarn25.

At Edulearn in Mallorca. Presenting paper about teaching wireless comms.

Extract from Deighton’s novel “Horse Underwater”.

My favourite Deighton is “Horse underwater”. Here’s the narrator (same character as in “The Ipcress File”) describing the first lesson of a navy diving class. I was impressed with CPO Edwards’ classroom management style.

Numbers App output of humidity plot.

Want to be able to access data via webserver on RPi as a plot. Stop gap is to use the very good Numbers App but interface with webserver a bit clunky. Might look at JavaScript plotting.

Four battery powered sensors.

Four of them talking to the Raspberry Pi.

Battery powered temperature and humidity sensor with ESP32 microcontroller.

Electronics and programming done. Still some coding to do on the Pi.

Motorbike battery and step down transformer.

I’ve got a 12V motorbike battery but the step down transformer I’ve got has an output current limit of 2.1A. Raspberry Pi5 likes 5A. Will need a different transformer.
