On 2nd May 2015, Alex from United Kingdom made a world record of covering 52.937 Kms in one hour on a bicycle. That means he must have been at a speed of 52.937 km/hr. Wow!
A tachometer usually shows you revolutions per minute on a calibrated analogue dial or a digital screen. But Nikodem here, from Poland, made a bike tachometer which not only shows you your speed, but your average speed, the temperature, trip time and total distance covered. That’s not even the best thing. The best thing is, it is DIY-able. Oh and also, he is just 15 years old. So either this guy is a genius, which he is, or this project is not as difficult as it sounds.
He has furnished a complete list of instructions, with videos and pictures included. You will need Arduino, bike with a reed switch, 16×2 LCD display, a servo, breadboard, thermometer, resistor, switch, button, a 10 ohms potentiometer, battery, cables, a box to hold all of this and some drilling and soldering tools. All the things are easily available.
A little bit of curiosity was all this lad needed to build this really cool bike tachometer. In his blog, he has shown complete connections and if we were to go by the video he has shared, it took him less than 5 minutes to assemble all of it.
Excuse us, while we go and build our own Bike Tachometer. And break some records!
