Also, the rate of hardware Kickstarters that have been or will be funded, but won't deliver anything is going to get through the roof.

Now is probably a great time for distributed manufacturing of essential devices using as much locally sourceable components as possible, and applying the OSHW principles not only to the device itself pour also to tools for validation, manufacturing, QA testing and repair.

#juketodon A gem, from Ye Olde 2007's Youtube, by artist Equalibrum.

« We all know that time is limited
That a day's worth has to be accomplished in the same finite 24 hours that we have
Some of us do it
Most do some of it
Some others procrastinate
And some never get around to it
Those that get things done, and do them well, know the right way
And that's time management
Time

Anybody has pointer on how to do "test farm" to automate parts of firmware validation on low-power wireless devices?
From what I've found so far, seems the concept has only been applied to Linux embedded stuff and other "big" targets.

More than four decades after this tech was introduced we could have had a Europe-wide dense network, cross-linking all regional centers from Oulu to Seville, Edinburgh to Athens, Brest to Luhansk. Maybe we could have had sleeper high speed trains. Maybe we could have closed many airports, and made flying very unappealing, without antagonizing families and friends that live scattered away.

But we don't have any of that.

Instead of building and operating infrastructure for the common good, we have elected and non-elected moronic bean-counters forcing what should be public utilities to compete with each other in a race to the bottom.

"Tailpipe" emission is zero, lifecycle emission is around 3 grams CO2 equivalent per passenger*kilometer, significantly less emissions that a _mechanical bike_ ridden by someone with a _fully vegan diet_.

Hypothetical medium range "clean" planes, or plans for highway with hydrogen refill stations, are a foolish distraction from the fact that **sustainable transcontinental long distance mobility is a solved problem, with well defined advantages, limitations and a proven track record**.

#POV #train #TGV
You're traversing a continent at nearly 300 kilometer per hour, in relative silence, high comfort and with an incredibly high level of safety.
This is a double-deck double-train, so around 900 passengers are enjoying the same journey.

This specific Lyon-Paris line was opened in 1981, one year after I was born. From the rolling stock to the infrastructure, most of this technology is more than 40 years old, with small incremental improvements here in there.

I have also added a WN30 remote temperature sensor to the system to monitor the temperature inside the fridge and it made me realize quickly that our fridge is dying and can't maintain a temperature below 10°C which is not at all acceptable for food safety.

I plan to add a second one to monitor the freezer separately.

Overall, I'm quite pleased by the Ecowitt system so far. It's basic, mostly unencrypted, open-ish, low-cost and low-friction.

New weather station installed at the family home. Hardware is by Ecowitt, it's quite low-cost, I'm curious to see how robust it is.
For Europe they recommend to order the 868 MHz version but because it's low-power and each sensor sends only a few bytes every minute, I've chosen to order the 433MHz version. I have thick walls and metal shutters to go though, so I thought it would help to use a lower license-free frequency. So far, it's working great.

The GW2000 base station (connected to the internet router) gives temperature, humidity inside the house and atmospheric pressure. I have chose the GW2000 because it has an Ethernet port and can be plugged into my router instead of the cheaper GW1100 that can only work through wifi.

The sensor on the left of the picture is a WH32 outdoor sensor giving temperature and humidity, it's under a radiation shield. The one on the right is a WH40 rain gauge with additional protection against birds. In the future I plan to install a wind speed and direction sensor (WS68 most probably) but they will be separated from the rain sensor and mounted on the roof, a must to get accurate wind measurement as the garden is full of trees and big shrubs.
Ecowitt has several "all in one sensors" but they won't work for me: if I put them on the roof, it becomes hard to clean the rain gauge regularly (and this is more or less mandatory), if I put them in the garden the wind measurement will be garbage.

All data is pushed to https://www.ecowitt.net/ in my private account and I can decide to share some of the channels on the public map.

A decade ago, the #OLPC had a screen that could work in 2 modes: normal LCD with colour, and low-power sun-readable monochrome. The techno was by #PixelQi. That company tanked but apparently https://www.tripuso.com/index.html is still selling 7 inches screens with the techno. Anyone bought some from them? Do you know of any other tech that is similar (fast color & e-ink-like monochrome)?

News from the UK: the real estate mafia is acting in plain sight and unimpeded. 🧐

Can they torch a building they just bought? Yes.
Can they bring heavy equipment on a crime scene a day latter, and erase all evidence without being bothered by the police? Yes, they also can.

The RX/TX way naming of nets is inherited from a previous era, when there were a clear distinction between DCE and DTE, terminals and modems. Now that all electronics systems are like matryoshka dolls of smart-ish subsystems and that it's not always clear who is "in charge" of a serial communication, shouldn't we use different names altogether to put the old way of naming things to a final rest?

How about ASI/ASO for pins and ASAB/ASBA for nets:
- Asynchronous Serial In
- Asynchronous Serial Out
- Async Serial A to B
- Async Serial B to A

ASO --> ASAB -->ASI
ASI <-- ASBA <-- ASO

Short, unambiguous, we just have to pick arbitrarily who's A and who's B amongst the two sides of a given interface.
No "crossover point", over a jumper or a connector, where the TX net *has to* become the RX net for the communication to work.

Also, no collision with the recommended new terminology for SPI https://www.oshwa.org/a-resolution-to-redefine-spi-signal-names/
