News Raspberry Pi computer, is it rational?

This looks like its useful if you are going vertical!

I'll use hot glue with glitters for that :lol:

Pi 3B+ is out of stock, practically everywhere. Seriously? A lot of people still have a lot of concerns about the Pi 4, and the previous model goes out of production immediately?
This could actually be a problem.

Still you could also get comparable boards from other brands...

 

[jedidia]

Yeah, but they'll have quirks we don't know yet, we're not sure whether our CD works with their OSes without hickups, we have to put them through environment testing... sigh.

Not after i have spent quite a bit of effort making low-level software working with RPi (and around all it's quirks)...

Something for the road!

Well, that makes sourcing really easy, if you exploit the quirks of certain boards...

Does anybody have an original SID chip around, BTW?

 

[jedidia]

Ok, apparently not so bad, just some supply difficulties until January. Not sure why, but apparently there will be new stock next year.
Meanwhile, we found a batch to bridge the time until then. That means we can take time testing the Pi4, which is great.

Sure, two actually! But they are not for sale :nono:

I know, those with the proper design error are already so rare, that you can only inherit them. :lol:

Perhaps this is why they're out of stock? :lol:

Handy little board if you are into pollution?

You can put one in the bathroom and write the highscores to an online leaderboard? :lol:

 

[Notebook]

Well, I'm not sure if the gas-analyser does Methane...?

You can implement Enviro+ in IoT applications as well. By connection it to Alexa you can get information about the temperature and humidity of the air by simply asking, or there's also an option to set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level etc.

So you could get a sound and light show if a guest exceeds set levels in the bathroom?

 

[Marijn]

If you add one of these: https://www.seeedstudio.com/Grove-Gas-Sensor-MQ2.html
you'll get LPG, i-butane, methane, alcohol, Hydrogen etc.

and one of these: https://www.seeedstudio.com/Grove-Air-quality-sensor-v1-3-p-2439.html
adds carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases.

So it can be done..

 

[Notebook]

Wow, you could do complete gaseous analysis of someone!

I am looking for a way to control a Bluetooth Low Energy RGB LED bulb from a single board computer.

This article describes a method: https://medium.com/@urish/reverse-engineering-a-bluetooth-lightbulb-56580fcb7546

I bought a bulb (Eglo Crosslink), but the values I get are much more cryptic than in the tutorial. I can't recognize anything which looks like a color definition.

Anybody here on the forum who could help me hacking these bulbs?

Germany is launching ESP32's (my new hobby) and Raspberry Pi Zero W's into space from Sweden to test high speed sensors and intensive computing tasks:

Seems fun
