Re: A Light OS for PI Zero / Browser

Great tips and ideas guys thanks!

I've never been brave enough to actually even build a binary from source never mind an entire OS but you only live once...

Re: A Light OS for PI Zero / Browser

It may be an irrational distrust of clutter or the aesthetic desire for neatness and order and an efficient bare-bones purpose-built computer.

The old engineer‘s adage is: build it, make it work and then... take bits off it until it stops working. Replace last bit and you’re done. ;-)

Re: A Light OS for PI Zero / Browser

Thanks, I'll be checking that out.

Raspbian is pretty weighty. What percentage of users need Mathematica? (700MB) and yet it takes nearly a fifth of the install!

A Light OS for PI Zero / Browser

I want to use the Pi Zero as an info board to display a web page. The (old fashioned) engineer in me balks at the idea of needing multi-Gigabyte sized OS in order to achieve this.

What is the smallest, lightest conceivable OS for Pi Zero that can display HTML, CSS and some images?

Re: GPIO22 Toasted - Remapping JSTEST

I finally managed to remap inside EmulationStation. One more issue though: I had LEFT on GPIO27 (pull-up). I measure HIGH (3.2V) at rest and LOW (0V) when I push the JoyStick Left. My Python program confirms this as does a GPIO UI. The left axis looks fine electronically and via software. HOWEVER, j...

Re: GPIO22 Toasted - Remapping JSTEST

My code only sets the ports as inputs with pull-ups. Where is the mapping?

Why will the CPU fail soon??

GPIO22 Toasted - Remapping JSTEST

I've wired a joystick and 6 buttons to my Pi (3B) using GPIO pins. At some point I think fried GPIO22 which was previously working fine as RIGHT. Never solder while your Pi is on kids... I've been baffled by the default mapping which jstest just seemed to know: GPIO04 = UP GPIO17 = DOWN GPIO27 = LEF...

Re: Preloaded Retropie Image won't Boot

Booting with pins 5-6 shorted made no difference at all. Did the Pi3 completely remove any way to "safe boot" as is indicated http://elinux.org/RPI_safe_mode?

Preloaded Retropie Image won't Boot

Procured a preloaded Retropie Image and wrote it to a brand new, formatted SanDisk 32Gb Class 10 micro SD. When I boot there are several errors and then it just hangs indefinitely. If I press Ctrl+Alt+Del it reboots to the same point. No prompt just stops. The Pi3b is working perfectly with another ...

Re: Removing OS's post Noobs installs

It seems the new location of the OS file is /media/pi/SETTINGS/installed_os.json (note the /pi subdirectory).

Also, I did not have any partition 3.

I've made a small guide for future reference here:

Startup Scripts

I'm having 2 issues with startup scripts. I have 2 requirements: 1) I want a keyboard key remapped so I want a "xmodmap" run on each boot 2) I want a basic 3-choice menu run when I boot which I have done with a simple bash script (using read) I added both commands to ~/.bashrc but it's not working a...

Re: NOOBS vs NOOBS Lite

If you want to save 1.2GB use plain Raspbian image and get rid of NOOBS completely.
It seems, from the current Raspian download page, that Raspbian is 4Gb:
"The Raspbian with PIXEL image contained in the ZIP archive is over 4GB in size..."
So I'm wondering: isn't Noobs actually smaller?
