Raspberry Pi in July
Emphasis: Get it working and do stuff!
F5 to full size the slide.
Talking about 2 Raspberry Pi’s
R Pi 3 + $35 using it to run slide show
R Pi Zero W $10 get it working.
Both of these often available at MicroCenter five bucks off.
On March 14 I got the Pi Zero W for $3.14 1

First 3 make it a W.
The rest are R Pi Zero specs 3

4. Hardware for a Raspberry Pi
Monitor – TV with HDMI
Micro SD card
HDMI cable (one end mini for Pi Zero)
USB Mouse and Keyboard (end micro for Pi Zero)
Power – 5 volts, 2 amps – micro USB
CTRL – Shift – 5 to get back to
Have Pi Zero in camera – explain focus
Monitor: I’m using a projector
How many of you have a projector at home with HDMI
So I brought along a TV
Micro SD: must have an OS on it (got some 32g from MicroCenter for 8 bucks)
HDMI cable: since I’m working with a Zero I have a special one miniHDMI
USB Mouse and Keyboard: for Pi Zero micro USB and only one.
Power: microUSB
Wall wart
battery 4

5. Software for the Pi: Raspbian
Install Raspbian
Configure Raspbian
sudo raspi-config or navigate the menus
sudo reboot
sudo apt-get update
sudo apt-get dist_upgrade
Raspbian: the official Raspberry Pi Linux OS. 32 bit.
Where to get Raspbian
How to install Raspbian
Use Etcher
Configuing Raspbian:
Latest Raspbian it’s just a wizard 5

6. Python learning tool (as in Monty, not snake)
Programming  Python That brings up IDLE (Eric Idle)
That gets you the REPL (Read Evaluate Print Loop)
File  New File that gets you to the editor
Show that it comes up on the Pi Zero
Go over slide
Demo on the Pi 3+
Show language selections
Go to Python3 do some math 6

Show the python code
Talk about Antenna Analyser
Need ADC – Pi has no analog pins MCP3008
If going to 5v need optocouplers to protect Pi 7

8. TAPR’s WSPR hat for the Raspberry Pi
Download and compile code:
sudo apt-get install git
git clone
cd WsprryPi
make
Install to /usr/local/bin:
sudo make install
 Run
sudo ./wspr N9NNN EM m
Go through slide
Show Pi with WSPR hat
Go to WSPR Map website 8

9. How to set up the RTLSDR
sudo apt update
sudo apt install gnuradio libvolk1-bin libusb gr-iqbal
sudo apt install qt5-default libqt5svg5 libportaudio2
sudo cp udev/*.rules /etc/udev/rules.d/
Configure Input output Device
Device: Realtek
Input Rate: 2,400,000
FFT Settings:
FFT Size: 1024
Rate: 5
