Hot Camera Contest: Build A Battery Powered Thermal Camera

Here’s a challenge for all you hardware hackers out there. Peter Jansen has opened up the Hot Camera Contest on Hackaday.io to use a thermal imaging camera in a battery-powered project.

The challenge here is simple. Use a Flir Lepton thermal imaging camera module in a battery-powered configuration. There’s a catch, though: this is a project to use the Lepton in radiometric mode, where the camera spits out an actual temperature value for each pixel. Yes, this is a documented feature in the Flir Lepton module, but so far very few people are using it, and no one has done it with a small, battery-powered device.

The rules for this challenge are to use the Flir Lepton 2.5 in radiometric mode using either the Raspberry Pi Zero W or ESP32. Any software in this challenge must spit out absolute temperature values in a text format, and there must be a demonstration of putting the Flir Lepton into low-power mode. There are two challenges here, one for the Raspi and one for the ESP32; and winner will be named for each.

Micro TV-B-Gone

Micro TV-B-Gone

The Micro TV-B-Gone is based off of Adafruit’s original TV-B-Gone kit, except made to be as small as possible, using an LIR-2032 coin cell.

I based this project off of the Adafruit TV-B-Gone kit. I wanted to start getting into using surface mount components on my projects, and seeing as the TV-B-Gone was my first foray into soldering, I figured that it would be a great project to work on.

The device takes a rechargeable LIR-2032 battery, and is activated pressing the single button on top. It will run through all TV power codes, and then go into a low power mode, waiting for the next button press. The battery will last around 40 full cycles, before being reduced down to 3.5 volts.

SIS-2 Universal Remote Receiver

Jeremy Cook writes on the Tindie blog about this IR receiver board by Atomsofttech:

SIS-2 Universal Remote Receiver

When you think of a “universal remote,” you generally picture an infrared (IR) emitter that can be setup to control your TV, AV receiver, and any other number of devices that work using IR signals. On the other hand, what’s to keep someone from doing the opposite, and having a universal receiver that can be programmed to accept codes from a remote that you just have lying around?
