New Project! Apollo Pi Thermal Camera

This vintage Apollo microwave detector now has a shiny new purpose as a thermal camera, powered by a Raspberry Pi Zero with an Adafruit thermal camera sensor taking the temperatures, displaying the results in real-time on a bright 1.3″ TFT display.

It has a Preset and a Dynamic mode – in the first the colours shown on screen are based on hard-coded temperature thresholds, and in the second the colour range can be adjusted using temperature sliders on an Adafruit.io dashboard.The dashboard also instantly displays any snapshots uploaded by the device, which are captured using the original thumb button on the grip.

The whole system is powered by a thin, cylindrical USB battery pack concealed in the hand grip, which can be easily recharged by popping off the nose cone and plugging in a USB lead.

Just three Python scripts control the menu logic, sensor and Adafruit.io integration, with the display handled by PyGame.

Working on this project has really helped keep me positive during lockdown, and with the extra time on our hands the kids & I have found many interesting things around the house to point it at!

The write-ups are available on Instructables and Hackster, and the scripts are on GitHub as usual.
