Re: an offline page w/Apache - can I connect without internet? please help a newbie understand...

Can I configure the RPI 3b+ as an "access point" so users could connect directly to the page with their smartphones?
Yes. See https://www.raspberrypi.org/documentati ... s-point.md

Re: Arduino does not recieve value from raspberry pi

Should

Code: Select all

 s1.write(z.enocde())
actually be

Code: Select all

 s1.write(z.encode())
?

p.s. It greatly helps to put your code (especially Python which is sensitive to indentation) between code tags (click "Code" on formatting menu when creating your post, then paste in your code).

Re: Apollo Guidance Computer on Pi

As the 50th anniversary of Apollo 11 approaches, I had to check this out. Thanks to Davespice's original post and dgordon42's updated link to the code, I was successful in setting it up and running it on a Pi 3B+ running Stretch (appeared to be version issues with the prerequisite packages on Buster...

Re: Dropped packets over wifi between Pi Zero W and Pi 3B+

... Does anybody out there have a 3B+ and a Zero W - and the time and inclination - to try to replicate what I'm seeing? I don't have exactly the same configuration as you, but here's a little data in case it's helpful (dropped 2 of 1000 packets): RPi3B+ (CoconutCream) as WiFi AP connected to I'net...

Re: Anyone using a Pi (as a tablet) as their main computer?

I have a Raspberry Pi 7" touch screen, but I haven't really used it much. It was originally for a project to replace a sea chart (they are absurdly expensive), and while it worked, it unfortunately wasn't good enough because we couldn't find a good sea map, which lead to the image being very blurry...

Re: hardware pinouts

https://www.raspberrypi.org/documentation/hardware/raspberrypi/README.md is probably the place to start. https://pinout.xyz/pinout is very helpful for identifying the different GPIO pins. If you're looking to connect another computer running a terminal emulator to the RPi's console, see https://pin...

Re: Issue #57 Hack a Dash Button

Thank you rpiMike ! This works (much better) on my Pi Zero W running Raspbian Stretch. There does seem to be an issue where the first press of a button after a long interval (couple of minutes) doesn't seem to be detected, but subsequent presses are. I modified the code to scan for any of multiple b...

Re: Restart network without reboot

Thanks for that info pcmanbob.

On my headless Pi Zero W running Raspian Stretch, I tweaked it a bit in a shell script to:

Code: Select all

sudo ifconfig wlan0 down
sleep 30
sudo ifconfig wlan0 up
The 30 second delay lets me turn on the WiFi hotspot on my laptop that I want the RPi to reconnect to.
