Program ATtiny 0-Series Chips with a Miniature UPDI Dongle
Thanks to their tiny size and improved capabilities, the ATtiny-0-Series of microcontrollers have been a delight for designers and DIYers looking for a microcontroller with the ease of use associated with the Arduino boards, but with a way smaller form factor associated with ATtiny microcontrollers.
Portable Fine Dust PM10 Analyzer with Large OLED Digits
In one of our previous articles, we built a DIY air quality monitor which was based on measuring the amount of Hydrocarbon concentration in the air using the BME680 VOC Whisker.
60V to 5V @ 3.5A Buck converter with USB output
This is a 60V to 5V – 3.5A step down DC-DC converter based on TPS54360B from Texas Instruments.
New and Improved Geiger Counter – Now With WiFi!
In one of our previous tutorials, we examined the development of a DIY-Geiger Counter showing the efforts of “Instructable” user Prabhat who combined the ESP8266 with a touch screen display to create a truly intuitive version of his Geiger Counter.
Capacitive Touch Sensor Toggle Switch
Touch sensors are used in many applications, from remote controls, LED light controls to appliance control panels.
IoT: Log Sensor Data to Google Sheets using NodeMCU
Data is regarded as the major value proposition of IoT.
Current Limit Solid State Power Switch with Latch
The project published here is a solid-state power switch with current limiting that prevents damage to host devices from faulty load conditions.
USB Powered Audio Amplifier using MAX4298
USB powered mini speaker amplifier is conveniently powered by USB and it is simple to set up.
Arduino Air Quality Meter
Recent campaigns around environment pollution helped increase the awareness around it with more people beginning to monitor their pollution footprint while also paying attention to the quality of air they breathe in.
Tiny Reflow Controller with OLED display
Last time we examined how to build a DIY Reflow Oven controller using the Tiny Reflow Oven Controller v1 by Rocket Stream.
Lithium Coin Cell Charger for Rechargeable Coin Batteries
This versatile charger has been designed to charge Lithium Coin Cell Rechargeable CR2016/CR2025/CR2032 Coin Batteries.
Temperature Controlled FAN using ATtiny10
The electrons movement in electronic components lead to the generation of heat which when beyond certain thresholds, prevents some components from functioning properly and in others could lead to a catastrophic breakdown.
