Robot list

Iv'e been building robots lately, because I'm forgetful this is a checklist of stuff to install on SD cards.

1 Flash raspbian
2 Add ssh file to boot menu (so I can immediately login from SSH)
3 Add WiFi config file (so I dont have to set up on gui).
4 Add python files such as line follower program and set preferences to run as program

Boot and login via SSH

1 Run sudo raspi-config ...
change password
enable camera
enable SSH
enable I2C
enable remote gpio

2 Install explorer hat (or whatever motor controller your using)
3 Install inputs (sudo pip install inputs)
4 Update and reboot
5 Check everything works.


My WiFi config for quickness: (wpa_supplicant.conf)

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network=
{
ssid="your ssid"
psk="your ssid password"
key_mgmt=WPA-PSK
priority=10
}

My favorite Raspberry Pi projects

A list of my favorite Raspberry Pi projects.

PiDP-8
A clone of the PDP-8 computer, the face plate and switches are available as a kit from "Obsolesence guaranteed" website, it's an expensive kit at just over £100 (Raspberry Pi not included) with lots of tinkering longevity, avoid if you don't like soldering and a good few hours work, but the end result will give you a thing of retro beauty.


ISS-Above
A simple ISO image from ISS-Above, which you copy to an SD card, put in your Pi, connect to a monitor or TV for an out of this world live feed from the International space station, watching the sunrise it truly magnificent. 


Volumino
Limitless internet radio stations to listen to whatever your taste in music. I found "volumino" to be a great choice to write to an SD card, you will need some sort of Pi add-on to connect to speaker/s such as a Pirimoni speaker hat or for more power a Hi-Fi Berry amp, a nice simple interface, set your board type and wireless settings from your PC, phone or tablet, then lay back and enjoy a bit of Zen radio, bliss!


Retro Pi
The amount of games available for the Retro Pi image is staggering, I have a 32gb SD card almost full! Add different rom's once you have set up the main Retro Pi image for a trip back in time to Sonic the hedgehog or a classic ZX Spectrum game.


Pi Desktop
The latest Raspbian pixel image is perfectly usable for an every day computer now, the early Pi's were slow but the Pi 3 with Raspbian is a lot more polished, decent learning software by default and Minecraft is always great fun.
