Displaying Temperature Using RCX Sensor

The project uses an RCX temperature sensor to be able to display the temperature correctly with the aid of negative temperature coefficient (NTC) resistor.

Homemade Seismometer for Earthquake Recording

This project describes how a seismometer is sensitive enough to detect and record earthquakes by constructing it using readily available parts with accurate time marker ticks.

Shipping Scale Converted from Bathroom Scale

The project shows how a digital bathroom scale has been converted to a shipping scale in order to weigh medium to large items and boxes for shipping.

PIC Based Portable LCR Meter

The LCR meter project is based on dsPIC39F4012 microcontroller which can be used to analyze the analog performance of any analog device.

Electronic Counter with Quadrature Encoder

The counter project was created to read one or two digital or analog sensors and display the running total on an organic LED display.

Temperature Sensor for Veggie Oil Applications

Cars and trucks that are running on veggie oil would benefit on this easy to install temperature monitor since any veggie oil used in a diesel engine needs to be heated to ideally at least 160°F to achieve a low viscosity.
