Build a simple CO2 meter using Raspberry Pi 3!   This short tutorial shows how to build simple CO2 meter using CJMCU-8118 board and Raspberry Pi 3. This board uses CCS811 sensor. This sensor supports intelligent algorithms to process raw sensor measurements to output a TVOC value or equivalent CO2 (eCO2) levels, where the main cause of VOCs is from humans. CJMCU-8118 includes HDC1080 sensor. There is also list of available alternative boards with CCS811 sensor on the end of this video.   Read Build a simple CO2 meter using Raspberry Pi 3 via Adafruit   An interesting link found among my daily reading

Animated GIFS are everywhere these day, so you might as well have an easy way to make them. I am in the middle of checking out this app today! — Douglas iOS: Making GIFs yourself has always been a pretty involved process either made too simple to suit my desires or too complicated to be intuitive. GIF Toaster blends the best of both worlds, offering more than enough control over the GIFs you’re trying to create in an interface that’s simple to use and unobscured by ads (if you pay). It’s a must have app on your iOS device and has been praised by users familiar with the apps available for GIF-building. If you ever want to make a GIF with some pro-level tools, or desire more flexibility to customize your creation just the way you want it, GIF Toaster is a more than capable tool.

Arduino is on open-source electronics prototyping platform that lets you make interactive stuff without having a degree in electrical engineering. For about $25 you can buy a credit card sized circuit board that has input connections (for buttons, knobs, light sensors, microphones, humidity sensors, fart detectors, Internet signals, etc) and output connections (for servo motors, LEDs, buzzers, speakers, stepper motors, vibrators, etc). You write programs on your computer to tell the Arduino how to process the input signals and how to activate the output components. This program is uploaded to the Arduino's microprocessor, making it self-contained.

A demanding and yet really, really cool project. There is something special about the retro sound of an old school typewriter and to see it being used as a modern input device is mind-blowing. — Douglas I modified a vintage type writer to function as a USB keyboard using an Arduino and 50 phototransistors. The typewriter is a German Olympia Monica that I bought at a local flea market. For this project I created a simple PCB that carries the phototransistors and several multiplexers and decoders. The PCB is connected to the Arduino through a ribbon cable. I used an Arduino Leonardo, which can function as a USB input device.
