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.
Mini Speaker Attached Audio Amplifier using TS4871
This Mini Audio Power Amplifier is capable of delivering 1W of continuous RMS Output Power into 8 ohms load @ 5V.
PHmeter – Arduino pH meter
pH meters are scientific instruments used for measuring the activity and concentration of hydrogen-ions in water-based solutions, with the aim of indicating its acidity or alkalinity expressed as pH values.
