Accelerometer Dice with 123D Circuits

This is the project that got Autodesk's CEO Carl Bass a little extra attention from the TSA on his way to MakerFaire Tokyo.  Here's an article about that... We made this as way to demo a few things you can do with our apps, 123D Circuits and 123D Design :  Design circuits.  Simulate the circuits online.  3D Model online and prepare for 3D Printing. Here's how it works - pick up the die, shake it, watch whil ...

DIY Cycle Speedometer

This project came to my mind when doing my MEM (Mechanical Engineering Measurement) project, a subject in my B.tech. The idea is to measure the angular velocity of my bicycle's wheel. Thus knowing the diameter and the all time mathematical legend the pi(3.14) the speed can be calculated. Also knowing the number of time the wheel has rotated, the distance traveled can be easily known. As an added bonus, I de ...

Portal 2 Turret – Master Turret Control

This project is an extension or remix of my original Portal Turret on Instructables (Portal-2-Turret-Gun). It can also be used as a cheap controller to control anything that uses the nRF24L01 radio chip. The LCD screen is particularly useful when customizing. https://youtu.be/8gPdsQ2TPBI (It turns out to be quite useful in checking when my radios establish and lose connections with other nRF24L01's on the " ...

The Chug-O-Meter

Isn’t it nice when you can hit two birds with one stone? That’s exactly what we’ve done as we approach both Arduino Day and Saint Patrick’s Day with our version of the Chug-O-Meter! We absolutely loved what the circuit.io team did with their Chug Meter but thought that we could add more to its survivability while surrounded by inebriated merrymakers. To do this we changed the force sensor to regular switche ...

Arduino Projects: Audio VU Meter

Presented here is an Arduino based audio meter that uses a liquid crystal display (LCD). A VU meter or standard volume indicator (SVI) is a device that displays a representation of signal level in audio equipment. In this project, the intensity of left-channel and right-channel audio signals provided as input to Arduino UNO board is displayed as bars on the 16×2 LCD. In this circuit, analogue input pins of ...
