Re: Enhanced graphics for Raspbian Lite

Ok, headless mode not X11, never noticed that before. The default font can be changed? That Ubuntu font still looks like pixels so different rendering would not make any difference. It is also a san serif font, which will look different than the Raspbian font. Does anyone know how to change the defa...

Re: Enhanced graphics for Raspbian Lite

It is probably the X11 Desktop Design that makes it look better. You can start with Raspbian Lite and install a X11 Desktop. Many choices of X11 Desktops based on different Windowing managers. A search will find how too and some images. https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=133691&...

Re: The much heralded "Buster"- When?

Been a lot of testing and more Pi stuff has been up-streamed into Linux. Mid year was what I had been hearing last year/start of this year, getting close to that now. Buster freeze was in March 2019. So we are about half way though the 6 months the last one took? Before Xmas anyway? Making Raspbian ...

Re: A better raspian 4 pi zero

PiCore Linux runs pretty fast, very small too.
Even the TC Desktop is not too bad.

Raspbian is where you start learning , then you move on to other options.
If I need the Raspbian OS I update on a Pi3B then move the SD card to the Zero.

Re: "Security" camera.

For Zero's I usually start the SD cards in B+'s and once it is all working then plug it into a Zero
The WiFi is a bit of a pain. to setup.

All mine are Ethernet connected fixed installs with power.
Going to have to try Zero' Ws and 3A+ now.

Re: Simplest, smallest way to light a single led with a wind turbine

For a mini hydro generator demo unit I used a 100mm/4" dia disc with a bunch of magnets around it. The coil was removed from a 24V relay, it was able to light a LED at a few hundred RPM. But wind generators can go faster, so perhaps use the brushless motor from a DVD player. The model plane/drone ve...

Re: My own 8-bit RETRO Homecomputer: RhoCoCo

most modern monitors still accept VGA, and there are literally millions of VGA capable monitors still in use, so not having HDMI isn't much of a compromise. This was in my head when I saw a HDMI to VGA dongle in Daiso the other day. Did not even know they make those sorts of things. $25 AUD a bit h...

Re: Simplest, smallest way to light a single led with a wind turbine

Stepper motors make good generators as they are designed for lower speed.
But a single LED is not much power unless it is one of those 5W ones ;)
To get more power out of a DC motor you need to gear up the speed, those toy motors are 10,000+ RPM.

Re: Blue Robotics Bar 100

I found i2c a bit unreliable with Python on Linux. More of my python code was for error checking, trying many times until it got a value. Or waiting some time and trying again.
